ObjectiveTo characterize the evidence distribution and methodological quality of randomized controlled trials （RCTs） on oral Chinese herbal medicine （CHM） for atopic dermatitis （AD） based on evidence mapping. MethodsSeven databases （CNKI， Wanfang Data， VIP， CBM， Cochrane Library， PubMed， and Embase） and the Chinese Clinical Trial Registry were searched for the RCTs in Chinese and English. Evidence distribution was presented graphically and textually， and methodological quality was assessed via the Cochrane Risk of Bias tool （ROB 1.0）. ResultsA total of 168 RCTs were included. The number of annual publications showing an increasing trend， and 72.6% RCTs had sample sizes of 51-100 participants. The studies evaluated 108 distinct CHM interventions categorized as decoctions， granules， Chinese patent medicines， and extracts. Compound Glycyrrhizin was the most frequently used， followed by Xiaofengsan and Chushi Weiling decoction. Among the RCTs， 57.1% had the treatment courses of 4-8 weeks. Outcome measures predominantly focused on clinical response rate， skin lesion severity scores， and adverse events， with less attention to TCM symptom scores， skin barrier function， and relapse rates. The overall risk of bias was generally high. ConclusionWhile CHM for AD is a research hotspot and demonstrates clinical advantages， the related studies have problems such as unclear clinical positioning， poor research standardization and methodological quality， and insufficient prominence of TCM clinical advantages. Large-sample， methodologically rigorous， and high-quality studies are needed to enhance the evidence base for CHM in treating AD.

Objective To investigate the current status of radiation protection in non-medical radiation workplaces in Yantai, China, and to provide a scientific basis for occupational health management in non-medical radiation workplaces. Methods Non-medical radiation workplaces in Yantai were investigated using a questionnaire survey in 2022, including radiation source term, occupational health examination, personal dose monitoring, personal protective equipment, and radiation protection testing workplaces. Data were entered by a double-entry method and then analyzed. Results There were 56 non-medical radiation workplaces in Yantai, covering manufacturing, nonferrous metal ore mining, nuclear power plant, transportation, and technical services. There were 0 Class I radiation device, 150 Class II radiation devices, and 10 Class III radiation devices; there were 80 Class I radiation sources, 16 Class II radiation sources, 14 Class III radiation sources, 62 Class IV radiation sources, and 135 Class V radiation sources. There were 998 radiation workers, with an occupational health examination rate and personal dose monitoring rate of 98.3%. Among the 56 non-medical radiation workplaces, 47 (83.9%) were equipped with radiation protection monitoring instruments, 24 (51.1%) workplaces had verified the radiation protection monitoring instruments, with 2017 personal dose monitoring instruments and 2327 personal protective equipment in place, 42 (75%) workplaces carried out occupational health assessments, 44 (78.6%) workplaces carried out self-detection, and 53 (94.6%) workplaces carried out entrusting detections (monitoring pass rate: 100% [53/53]). The declaration rate of occupational hazard items was 87.5% (49/56). Conclusion There is still a gap between the current status and the requirements in the national regulations and standards regarding radiation protection in non-medical radiation workplaces. Therefore, the supervision and management of non-medical radiation workplaces should be further strengthened, especially the configuration and verification of radiation protection monitoring instruments.

[Objective]Using CiteSpace software to visualize and analyse the literature related to acupuncture treatment of post-stroke dysphagia in China,to reveal the dynamics of frontiers and the evolution of hotspots in this field,as well as provide suggestions and references for future research.[Methods]By searching the three major Chinese databases,China National Knowledge Internet(CNKI),Wanfang Data and China Science and Technology Journal Database(VIP),the literature related to acupuncture treatment of post-stroke dysphagia was retrieved between the establishment of these databases and June 2023.Then the data issuance,authors,institutions,keywords clustering and keywords emergence were analyzed and presented in a visualization map or chart with CiteSpace 6.1.R6 software.[Results]After searching and screening,a total of 1 585 relevant literatures were included,and the overall trend of the number of studies within the field showed a steady increase in terms of the number of publications.However,links among study authors are scattered and mostly intra-institutional.At the same time,the connection among institutions for cross-regional collaboration is not close enough.Keywords clustering analysis showed that the type of research in the literature mainly consists overviews and clinical randomized controlled trial(RCT).In terms of treatment approaches,the use of combination of multiple therapies is common.The time zone map reflects the continuous process of refinement of acupuncture therapies,from which the creation of a series of new types of acupuncture therapies could be observed.[Conclusion]The field of acupuncture for the treatment of post-stroke dysphagia is becoming increasingly sophisticated.It is predicted that the combination of acupuncture with other common therapies for the treatment of post-stroke dysphagia will remain a hot research topic in the coming years.Meanwhile,there will be a new trend towards integrating resources and conducting high-quality clinical studies with multi-centre collaboration.

Objective:To establish and verify a diagnostic model for distinguishing multiple sclerosis (MS) from other neurological diseases with similar symptoms by usingcerebrospinal fluid oligoclonal band (CSF-OCB)combined with IgG intrathecal synthesis indicators and biochemical markers.Methods:Multiple sclerosis (MS) patients admitted to the Neurology Department of Beijing Tiantan Hospital affiliated with Capital Medical University from January 2014 to December 2022 were selected as the case group, while patients with similar neurological symptoms were selected as the control group. Using the case-control study design, a retrospective analysis was conducted on the detection of age, gender, oligoclonal bands in cerebrospinal fluid, IgG intrathecal synthesis indicators and biochemical indicators for all study subjects. The differential diagnosis model was determined by the multiple logistic regression analysis, and the receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficiency of the differential diagnosis model for neurological diseases with similar symptoms to MS and other conditions.Results:This study included 167 patients in the case group and 335 patients in the control group, of which 128 patients in the case group and 265 patients in the control group were used to construct the model, and 39 patients in the case group and 70 patients in the control group were used for model validation. The differential diagnostic model constructed by a multivariate logistic regression model was Y=0.871×CSF-OCB-0.051×CSFprotein-0.231×CSFchloride+1.183×gender-0.036×LDH+35.770. The model showed that the area under the curve, sensitivity and specificity were respectively 0.916, 87.3% and 87.6%. The Delong test results showed that the diagnostic efficacy of the model was significantly different from OCB, IgG intrathecal synthesis indicators, and OCB combined with IgG intrathecal synthesis indicators ( P<0.05). The new model validation showed that the actual diagnostic consistency rate for the MS group was 84.6%, while the actual diagnostic consistency rate for the control group was 90.0%. Conclusion:This study combines OCB, IgG intrathecal synthesis indicators, and biochemical indicators to establish a diagnostic prediction model for neurological diseases with similar clinical symptoms in MS. This model may have good differential diagnostic value and can better assist clinical diagnosis in the early stages of disease progression in MS patients.

Objective: To propose reasonable suggestions to promote the standardization of clinical studies by reviewing the systematic reviews and meta-analyses of acupuncture-moxibustion treatment of essential hypertension (EH). Methods: Computer retrieval was conducted through Excerpta Medica Database (EMBASE), PubMed, China National Knowledge Infrastructure (CNKI), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), and Wanfang Academic Journal Full-text Database (Wanfang) to collect systematic reviews and meta-analyses relevant to treating EH with acupuncture-moxibustion therapy. The time range was from the database's inception till July, 2020. The studies were screened based on the inclusion and exclusion criteria and then data-extracted. The study's quality and evidence ratings were performed by referring to the preferred reporting items for systematic review and meta-analysis (PRISMA), a measurement tool to assess systematic reviews 2 (AMSTAR 2), and the grading of recommendations, assessment, development, and evaluation (GRADE). Results: A total of 14 studies, 10 in Chinese and 4 in English, published between 2012 and 2019, were included, involving 70 outcome measures. The methodological quality was rated as critically low, the reporting was relatively complete or had certain flaws, and the evidence strength was rated as low or very low. Conclusion: Regarding the acupuncture-moxibustion treatment of EH, the methodological quality and outcome measure evidence of existing systematic reviews and meta-analyses are relatively low, and the reporting quality also expects further improvements.

It is difficult to dissolve in water and has poor oral efficacy, but when combined with different substances or combined (forming phospholipid complex), its bioavailability can be improved, so as to improve its pharmacological efficacy.

Objective:To investigate the clinical effects of free descending branch tissue flap of lateral circumflex femoral artery in repairing Wagner grade 3 or 4 diabetic foot wounds.Methods:A retrospective observational study was conducted. From October 2019 to January 2022, 12 patients (10 males and 2 females, aged 38-66 years, with an average of 52 years) with diabetic foot wounds who met the inclusion criteria were admitted to the First People's Hospital of Yulin, of whom 5 cases being Wagner grade 3 and 7 cases being Wagner grade 4. Wound debridement and vacuum sealing drainage were performed to control infection, and the wound area after debridement was between 13 cm×6 cm and 28 cm×11 cm. The wounds were repaired with free descending branch tissue flaps of lateral circumflex femoral artery. Among them, the wounds of 4 cases were repaired with single flap of musculocutaneous branch or intermuscular branch of descending branch tissue flap of lateral circumflex femoral artery, 1 case with lobulated flap, 1 case with bilateral tandem flap, and 6 cases with chimeric lateral femoral muscle flap. The area of resected tissue flap was 9 cm×7 cm to 21 cm×10 cm; end-to-end anastomosis was selected between vessels in the donor sites and the recipient sites, and pressurized treatment should be performed if necessary. The donor site wounds of 10 patients were treated with cosmetic tension-relieving suture, and the donor site wounds of 2 patients were repaired with split-thickness skin graft from head. After operation, the condition of wound repair was recorded. After wound healing, the level of 2-hour postprandial blood glucose of patients was measured. During follow-up, the wound healing of the recipient site and scar formation of the donor site were observed. Before and 6 months after operation, computer tomography angiography was used to detect and compare the blood perfusion of the affected limb. At the last follow-up, the walking ability of the patients was recorded.Results:The wounds of 9 patients healed well after operation; the flaps in the recipient site of 2 patients were infected on postoperative day 5 after surgery and were repaired by suturing in stage Ⅱ after open drainage and inflammation control; the distal end of the grafted tandem flap in 1 patient gradually developed purple necrosis on postoperative day 4 and was repaired with a skin graft after debridement. After wound healing, the 2-hour postprandial blood glucose value of all patients was controlled in the range of 8-12 mmol/L. During Follow-up of 6 months to 1 year, 3 patients had partial ulceration in the plantar compression area, which healed after decompression combined with dressing change or flap repair, while the other 9 patients had no ulceration in the recipient area; the appearance of the affected foot was plump after wound healing, the transplanted flaps had good blood supply and good fit with the surrounding tissue, and were wear-resistant, but insensitive. During follow-up, only linear scar remained in the donor area of direct suture in 10 cases, and the skin grafts in the donor area were completely survived in 2 cases. Compared with the patency of the main blood vessels of the ankle joint segment of the affected limb before operation, the vascular network of the flap transplantation area in the affected foot was formed 6 months after operation. At the last follow-up, 8 patients could walk independently, and 4 patients could walk with crutches.Conclusions:The free descending branch tissue flap of lateral circumflex femoral artery is effective in repairing Wagner grade 3 or 4 diabetic foot wounds, which can shorten the course of disease and improve local blood flow.

Objective To investigate the clinical effects of treating traumatic lesions of the popliteal artery by staged stretching.Methods From July 2011 to March 2016,29 patients with traumatic lesion of the popliteal artery underwent staged stretching after direct end to end anastomosis at Department of Orthopaedics,The 9th People's Hospital of Wuxi.They were 19 males and 10 females,with a mean age of 38.3 years (range,from 16 to 61 years).The average length of popliteal artery lesions was 3.7 cm (range,from 2 to 5 cm).After the keen joint was immobilized at flexion by external fixation,direct end to end anastomosis was performed with a proper segmental vascular freedom.From 4 weeks after operation,the popliteal artery was stretched stage by stage to its original length by gradual adjustment of the external fixation till the knee joint was fully extended.The color,skin temperature,pulp tension and capillary reaction of the toes were closely observed after surgery.CT angiography (CTA) was performed 6 months after surgery.The active range of motion was assessed at 12 months after surgery for the knee and ankle joints on the injured limb.Results All the patients were available for an average follow-up of 2 years (range,from 1 to 3 years).Blood supply was good for all the affected limbs.The staged stretching of the popliteal artery resulted in no rupture of any anastomotic stoma or no thrombus.CTA at 6 months after surgery showed fine patency of the popliteal artery and no formation of false aneurysm or arteriovenous fistula.At 12 months after surgery,the knee function was excellent in 15 cases,good in 10 and fair in 4;the ankle function was excellent in 18 cases,good in 8 and fair in 3.Conclusion Staged stretching is a safe,convenient and effective treatment of traumatic lesions of the popliteal artery.
