The quality evaluation of the blind method is to evaluate the clinical blind data obtained from clinical trials adopting the blind method and judge the effectiveness of the blind method by investigating the blind effect of different blind objects. A successful blind method can avoid the influence of subjective factors on the test results of subjects and researchers to a certain extent. The quality evaluation of the blind method can reflect not only the effectiveness of the blind method but also the accuracy and credibility of clinical trial results. In recent years， randomized controlled trials have been widely used in the evaluation of the clinical efficacy of traditional Chinese medicine （TCM）， but the quality of the implementation of blind methods is uneven， and the evaluation criteria have not yet been formed. In this paper， the data collection methods， calculation principles， advantages， and disadvantages of two quantitative quality evaluation methods of blind methods， namely James Blinding Index （JBI） and Bang Blinding Index （BBI）， were introduced. The two indexes were analyzed in a randomized controlled trial of acupuncture and moxibustion to relieve postoperative oral pain. The calculation process of the results was demonstrated by R software and visualized by forest map. At the same time， a tool table was designed to facilitate the collection of evaluation data of blind methods in TCM clinical trials at different stages. Finally， the necessity and feasibility of quality evaluation of blind method in TCM research were discussed to provide a basis for evaluating and improving the quality of blind method implementation in TCM clinical trials.

Objective To study the safety and effectiveness of chloral hydrate in children undergoing ABR tests.Methods From December 2015 to March 2022,5 513 children under the age of 12 were selected for ABR ex-amination in West China Hospital of Sichuan University,who received chloral hydrate sedation(dose of 30 mg/kg).Data on administration method(mixed or direct),sleep deprivation(yes or no),failure performance(such asfailure to sleep,insufficient sedation,superficial sleep),adverse events(vomiting,irritability,etc.)were retrospectively analyzed.Total sedation failure rate,sedation failure rates in different age groups(≤0.5 years,0.5～3 years,3～12 years)and adverse event rate were calculated.Results Among the 5 513 ABR tests,199(3.61％)failed seda-tion.The sedation failure rates in different age groups(≤0.5 years,0.5～3 years,3～12 years)were 3.03％,4.31％and 3.11％,respectively.In the sedation failure tests,insufficient sedation was found in 81.91％of the tests.The incidence of adverse events was 10.55％,with most commonly vomiting.Conclusion The sedation fail-ure rate and the incidence of adverse events of chloral hydrate at 30 mg/kg were relatively low,thus chloral hydrate can be considered safe and effective at this dose.

ObjectiveTo evaluate the methodological quality of traditional Chinese medicine （TCM） diagnosis and treatment guidelines/consensus of constipation with Appraisal of Guidelines for Research and Evaluation Ⅱ （AGREE Ⅱ）tool， and to study the attention situation of the included Chinese patent medicines in China's National Reimbursement Drug List in the guidelines/consensus. MethodThe data of CNKI，VIP，Wanfang Data，SinoMed，PubMed and Cochrane from the inception of the databases to October 2021 were searched to collect the TCM diagnosis and treatment guidelines/consensus of constipation. Then，the diagnosis and treatment standards and recommended Chinese patent medicines were extracted. Two researchers assessed the methodological quality of the guidelines/consensus with AGREE Ⅱ tool independently. The quality of reports was evaluated by Reporting Items for practice Guidelines in HealThcare （RIGHT） Statement. The recommended Chinese patent medicines in the guidelines/consensus were compared with those in the National Reimbursement Drug List. ResultEleven consensus and 2 guidelines were included，involving 794 experts. The scores of AGREE II were clarity of presentation（59.0%），scope and purpose（44.0%），stakeholder involvement（23.1%），rigor of development （12.1%），applicability （11.1%），and editorial independence （8.3%） from high to low. Five articles were recommended at B level（recommended after revision） and 8 articles were at C level （not recommended）. The average scores of RIGHT Statement were as follows：basic information （93.59%），background （57.69%），evidence （18.46%），recommendations （20.88%），review and quality assurance （19.23%），funding，declaration and management of interests （0.00%）， and other information （0.00%）. The included guidelines/consensus recommended a total of 27 Chinese patent medicines，among which 20 were included in the National Reimbursement Drug List，with 4 species of Class A and 16 species of Class B， accounting for 74.1% of all recommended Chinese patent medicines. Ten purgative Chinese patent medicines in the National Reimbursement Drug List were recommended by the guidelines/consensus，accounting for 50% of all purgative drugs， and 8 were not recommended. There were prescriptions for purgation， for promoting digestion and removing food stagnation， for clearing heat and purging fire，and for warming the middle and dissipating cold，Tibetan medicine and Mongolian medicine. ConclusionBy the AGREE Ⅱ assessment，the methodological quality of the TCM diagnosis and treatment guidelines/consensus of constipation included in this study needed to be improved in the future. The report quality evaluated with RIGHT Statement was low. Most drugs included in the National Reimbursement Drug List were paid attention in the TCM diagnosis and treatment guidelines/consensus of constipation. Moreover，the drugs included in the National Reimbursement Drug List could basically fulfill the clinical needs reflexed from the guidelines/consensus recommendations. However， the reasons of some drugs failing to be included in the National Reimbursement Drug List needed to be studied in the future.

Objective:To investigate radiation-induced somatic mutations and variations and provide theoretical basis for clarifying radiation-induced genetic changes and long-term effects by whole-genome sequencing analysis of the genetic variations of the victim of the " 5.7" 192Ir radiation accident in Nanjing. Methods:Normal back skin tissue, irradiated bone and soft tissues, and peripheral blood were collected from the victim 2 047 days post-irradiation. DNA of these samples was extracted and sequenced with high-throughput genomics and analyzed by bioinformatics method. The genetic variations of between irradiated and normal tissues were compared.Results:Compared with normal back skin tissue, there are large amounts of genetic variations in the irradiated bone and soft tissues and peripheral blood, including base substitution (transition, transversion), small insertion, small deletion, copy number variation (gain, loss) and structure variation (large deletion, large duplication, inversion, intra-chromosomal translocation, inter-chromosomal translocation). There were 10 666 genetic variations in the irradiated bone and soft tissues and 11 233 genetic variations in peripheral blood, where thousands of genes were involved in. These variations occurred in the exons, introns, UTR′3, UTR′5, splicing sites, within 5 kb upstream of transcription initiation site, within 5 kb downstream of transcription termination site, ncRNA and intergenic region. All chromosomes had genetic variations.Conclusions:There were a large number of genetic variations in the irradiated tissues and blood of the victim at 2 047 days after irradiation, which may affect the body function and cause the long-term effects.

Objective:To investigate the role of concurrent chemoradiotherapy in the treatment of limited-stage small cell lung cancer (LS-SCLC) and the impact of the number of chemotherapy cycle during radiotherapy (RT) on clinical prognosis.Methods:Patients with LS-SCLC treated with definitive radiotherapy from May, 2008 to September, 2016 were included in the study. The primary endpoint was overall survival (OS), which was calculated from the start of treatment to the date of death or last follow-up. The effect of the number of concurrent chemotherapy cycle and other clinical factors on clinical efficacy was analyzed. Survival analysis was performed with Kaplan- Meier method, and multivariate analysis was performed with Cox regression model. Results:Three hundred and seventeen patients were eligible for the analysis. Among them, 129 patients received sequential chemoradiotherapy and 188 patients received concurrent chemoradiotherapy. Among patients receiving concurrent chemoradiotherapy, 86 patients received 1 cycle of concurrent chemotherapy and 102 cases of 2 cycles of concurrent chemotherapy. The median follow-up time was 22.47 months. Multivariate survival analysis showed that only clinical stage, timing of RT administration and prophylactic cranial irradiation (PCI) were the independent prognostic factor for OS. The median OS in patients who received 1 cycle and 2 cycles of concurrent chemotherapy during RT were 33.8 months and 30.4 months ( P=0.400). No matter in elder patients or in younger patients, in early RT group or in late RT group and application of PCI or not, the number of concurrent chemotherapy cycle exerted no significant impact on OS. The incidence of grade 3 or above adverse events was 20% in the 1-cycle concurrent chemotherapy group, and 13.7% in the 2-cycle concurrent chemotherapy group. Conclusions:Concurrent chemoradiotherapy is the standard treatment of LS-SCLC. Two cycles of concurrent chemotherapy during RT is not necessarily superior to 1 cycle of concurrent chemotherapy. The optimal number of concurrent chemotherapy cycle during RT need to be studied in a large prospective randomized clinical trial.

Objective:To evaluate the clinical effectiveness and safety of Jiuwei-Zhuhuang San plus amoxilcillin sodium and sulbactam sodium in the treatment of bacterial pneumonia in children. Methods:A total of 120 patients with bacterial pneumonia in children from 1 year to 14 years old were randomly divided into the study group ( n=90) and the control group ( n=30) with ratio 3 to 1, the random sequence created by SAS software. Both groups were treated with amoxilcillin sodium for basic treatment, the observation group was treated with Jiuwei-Zhuhuang San. Both groups were treated for 1 week and followed up for 1 week. The cough frequency, clinical effective rate, symptoms and signs score, Traditonal Chinese medicine (TCM) pattern scores and adverse event rate were observed. Results:Eighteen cases were dropped and eliminated in the observation group, and 4 cases were dropped and eliminated in the control group, so 72 of observation group and 26 of control group were analyzed. After treatment, the clinical effective rate of the observation group was 27.8% (20/72), and the control group was 0% (0/26), where the difference was significant ( χ2=7.445, P=0.006). The difference of TCM syndrome score before and after treatment in the observation group (-16.8 ± 8.2 vs. -11.0 ± 5.8, t=-3.858) was lower than that of the control group ( P<0.01). There was significant difference between the two groups ( Z=-2.347, P= 0.019) in the TCM syndrome. The cough frequency of the observation group was 41.7% (30/72), and the control group was 26.9% (7/26). There wasn’t any significant differences in the cough frequency between two groups ( P>0.05). There was no statistical difference in symptoms and signs score or adverse event rate between two groups ( P>0.05). Conclusion:On the basis of amoxicillin sodium and sulbactam sodium, combined use of Jiuwei-Zhuhuang San can improve the clinical effectiveness of children with bacterial pneumonia.

Objective: To evaluate the parabiotic tissue protection concept in the repairment of acute radiation-induced skin injury. Methods: Seven patients(3 males and 4 females) with acute radiation injury treated in the Department of Plastic Surgery of the Second Affiliated Hospital of Soochow University from February 2014 to January 2018. The ages of patients ranged from 45 to 76 years. The wound areas include perineum and buttock (n=3), chest(n=2), and thigh(n=2). In the early stage, subregional " sandwich" surgical dressing was used to protect the probiotic tissue. Two months later, the necrotic tissue was clearly demarcated, the debridement was underwent, and the parabiotic tissue was preserved as far as possible. Vacuum sealing drainage(VSD)was applied to cover and soak wound with normal saline to moisturize the wound and promote the benign transformation of ecological tissue. Ten days later, the granulation grown well, and the skin flaps and myocutaneous flaps with good blood supply were designed to repair the wounds. The VSD device was continued to be used, to drain effusion under flap and promote the growth of cystic cavity granulation, with the purpose to promote blood supply of the skin flap, perform the final biological cleaning effect on the parabiotic tissue of the wound surface, promote the benign transformation of parabiotic tissue, and reduce the further necrosis. Results: Seven patients with Ⅳ degree acute radiation-induced injury wounds were treated 6-10 weeks for surgery preparation, and 2-4 weeks for VSD-application after debridement. Except for part of flap was necrotized on 10th day after the first operation in one patient, all the other patients achieved satisfied outcome in a surgery. There was no further radiation-induced ulcer occurred during the 0.5-3 years of follow-up. Conclusions The concept of parabiotic tissue protection during preoperative, intraoperative and postoperative recovery phase can promote parabiotic tissue transformed to a good result after acute radiation injury, and reduce the size and depth of soft tissue necrosis, which can provide a good foundation for the secondary repair with flap and reduce complications.
