There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Radiotherapy is one of the main treatments for head and neck Carcinoma. The incidence of radiotherapy-related adverse events is greater than 90%, and severe adverse events may lead to the interruption of radiotherapy. Interruption of radiotherapy on the one hand affects the efficacy of tumor treatment, on the other hand seriously affects the quality of life of patients. Investigators intend to conduct a randomized, controlled clinical study of multidisciplinary nutritional and psychological care for patients receiving radiotherapy for head and neck carcinoma, with a view to reducing the rate of radiotherapy interruption and improving the quality of life of patients with radiotherapy for head and neck carcinoma through a whole-course multidisciplinary care model.
1. Androgenic alopecia (AGA) is a clinically common non cicatricial, progressive hair follicle microminiaturization disorder that begins in puberty or after puberty. The latest epidemiological survey shows that the prevalence rate of males in China is about 21.3%. In 2021, Nature published an article stating that stress hormones can inhibit hair growth by regulating hair follicle stem cells. This research conclusion provides new evidence for the impact of stress on hair growth. The trend of receiving AGA patients in the investigators' outpatient department is increasing. How to provide rapid, safe, and effective treatment for AGA patients is currently a hot topic for clinicians. 2. Studies have shown that phototherapy can effectively improve androgenic alopecia, alopecia areata, and hair loss after chemotherapy, and promote hair growth. At the same time, phototherapy can also be adjusted by adjusting the expression of reductase genes and vascular endothelial growth factor genes, as well as some endogenous epidermal growth factors, such as fibroblast growth factor and insulin-like growth factor, are also upregulated, which can stimulate hair growth. 3.1565 nm non-ablative fractional laser has the effects of inhibiting sebaceous gland secretion of oil, regulating collagen metabolism, and delaying changes in scalp collagen after hair loss. Previous studies have confirmed that 1565 nm non-ablative fractional laser therapy for alopecia areata has a good effect. Its possible mechanisms include increasing local blood flow, stimulating growth factors and cytokines during hair growth. At the same time, in order to achieve low energy, safe, and effective treatment without the need for hair cutting, the investigators had for the first time improved the 1565 nm non non-ablative fractional laser treatment tool, removing the original sapphire crystal cooling contact. This improvement can make the treatment head fully fit the scalp, and the excitation beam acts vertically on the treatment area, reducing energy attenuation.
1. Striae distensae (SD), also known as stretch marks, are common, permanent dermal lesions that can be symptomatic and are considered aesthetically undesirable; thus, they pose a significant psychosocial and therapeutic challenge. SD arise in areas of dermal stretching and most commonly occur on the abdomen, breasts, buttocks, and thighs. Most literature has described SD during pregnancy(striae gravidarum) and puberty, with reported prevalences varying from 11% to 88%. Hormonal influences, reduced genetic expression of fibronectin, collagen, and elastin, and mechanical stretching of the skin have all been postulated to contribute to SD formation. In the acute phase, SD appear as red/violaceous lesions (striae rubrae; SR) that can be raised and symptomatic. The chronic form (striae albae; SA) exists as hypopigmented dermal depressions. 2. Polylevolactic Acid(PLLA) is at present one of the most promising biodegradable polymers (biopolymers) and has been the subject of abundant literature over the last decade. PLLA can be processed with a large number of techniques and is commercially available (large-scale production) in a wide range of grades. 3. Previous studies have found that 1565-nm laser can promote the synthesis of types I, III, and VII collagen and elastin, as well as the remodeling of dermal collagen. According to previous studies, dermal collagen deposition and remodeling may be related to the mechanism by which 1565-nm laser improves SD.
This trial was conducted in a prospective, multicenter, randomized withdrawal design at a designated clinical trial facility. The total sample size for this trial is expected to be 59-62 patients. One to two subjects were conducted in each study center as a preliminary test. A total of about 3-6 subjects were selected for the pre-test. The pre-test subjects used the test equipment (on state) and were not randomized. The study was divided into screening/baseline period, treatment period (including test period, random withdrawal period and observation period) and follow-up period. All subjects underwent a 7-day baseline assessment (VAS score for at least 4 days) during the screening/baseline period. Eligible subjects underwent Peripheral Nerve Stimulation(PNS) surgery and implanted electrode leads and entered the 7-day test period. During the test period, subjects with an average VAS score improvement of ≥30%(VAS score for at least 4 days) will be randomly assigned to the experimental group (on state) or the control group (off state) in a 1:1 ratio for 7 days observation. All subjects were enrolled in the observation period until 28 days after implantation. Safety assessment was performed at a 14-day follow-up after removal of the device.

1 Materials and methods 1.1 Subjects From September 2021 to August 2022, the patients who received induction of labor by cervical double balloon combined with oxytocin in a Grade III A Maternal and Child Health Hospital in Changsha were included in the study. A double balloon and oxytocin induced labor at a tertiary maternal and child health centre in Changsha. Inclusion criteria: 1 age ≥18 years; 2 Singleton; 3 no vaginal infection, fetal membranes intact; 4 according with the indication of induced labor [5] ; These included delayed pregnancy, hypertensive disorder complicating pregnancy, diabetes mellitus, cervical Bishop score < 6, and negative oxytocin provocation test (Oct) . The exclusion criteria were: 1 abnormal head and pelvis, unable to be delivered vaginally; 2 twins; 3 maternal contraindication of vaginal delivery; 4 severe placental dysfunction, unable to tolerate vaginal delivery; 5 there were contraindications for the use of cervical balloon. 1.2 Methods 1.2.1 Operation Method First of all, pregnant women to introduce the procedure of placing the balloon, ease their fear, tension. Assist the patient to take the stone position, sterilize vulva 3 times, spread aseptic towel, expose cervix with vaginal speculum, sterilize vagina and cervix 3 times with iodine cotton ball, after sterilizing the cervical tube 3 times with iodine-complexed cotton swab, insert the disposable dilatation balloon (Henan Bonding Industry Co., Ltd., Yusheng Medical Supervision Machine No. 20180029, model: Type II 18F) into the cervical tube, until the two sacs into the cervical canal and ensure that the double sacs are through the cervical mouth, sub-turn to the cervical inside and outside sacs slowly injected saline 80 ml each. The end of the balloon catheter was fixed to the inner thigh of the pregnant woman with 3m adhesive tape, without restricting the physical activity of the pregnant woman. The operation process is smooth, the pregnant woman has no discomfort, before and after the operation monitoring fetal heart is normal, instructs the pregnant woman to test the fetal movement, closely observes the pregnant woman labor sign and the fetal intrauterine situation. The balloon is usually inserted between 16:00 and 18:00. The balloon is taken out at 8:00 am the next day, oxytocin (Ringe 500ml + oxytocin 2.5 U) was given intravenously to the patients who were not in Labor 1 hour after rupture of membranes. According to the frequency of uterine contractions, if there is no uterine contractions, increase the rate of dripping 8 drops/min, maximum dose not more than 40 drops, until regular uterine contractions, after every half-hour assessment. 1.2.2 Observation indicators Using the hospital electronic medical record information system to search and review the medical records of these women, the age, number of pregnancies, number of parturients, weight gain during pregnancy, height, weight, pre-and post-pregnancy body mass index (BMI) , indication of induced labor, pregnancy complications, gestational age at the time of balloon induced labor, neonatal weight, cervical Bishop score before and after balloon dilatation, occurrence of acute Chorioamnionitis, fetal distress, NST typing, mode of delivery, etc. . The clinical data of the patients who were induced by cervical double balloon combined with oxytocin were analyzed, and the related factors of pregnancy outcome were also discussed. 1.3 Statistical credits SPSS 25.0 was used to analyze the data. The mean ± standard deviation was used for statistical description and t-test was used for statistical analysis. The frequency was used for statistical description and chi-square test was used for statistical analysis. Binary logistic regression analysis was used to determine the influencing factors of different pregnancy modes, and the difference was statistically significant with P < 0.05.
Functional dyspepsia(FD) is most common in functional gastrointestinal disorders whose rick factors include sleep disturbances. The medication treatment for functional dyspepsia with sleep disturbances has disadvantages such as addiction and withdrawal symptoms. Transcutaneous auricular vagal nerve stimulation(taVNS) is a new therapeutic method to improve dyspepsia and sleep. Study on taSNS for FD with sleep disturbances has not yet been explored.
