OBJECTIVE: To observe the clinical efficacy of electroacupuncture (EA) at "four points of sacral region" for mild-to-moderate benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). METHODS: A total of 58 patients with BPH/LUTS were randomly divided into a sacral four-point EA group (29 cases, 1 case dropped out) and a conventional EA group (29 cases, 1 case dropped out). EA was applied at bilateral points 0.5 cun lateral to the sacrococcygeal joint and Huiyang (BL35) in the sacral four-point EA group; and was applied at Guanyuan (CV4), Zhongji (CV3), Qugu (CV2) and bilateral Shuidao (ST28), Sanyinjiao (SP6), Zusanli (ST36) in the conventional EA group. Both groups received continuous wave, 2 Hz in frequency, 30 min a time, once every other day, 3 times a week for 4 weeks. Before treatment, after 2 and 4 weeks of treatment, and in follow-up of 1 month after treatment completion, the international prostate symptom score (IPSS), the overactive bladder symptom score (OABSS), the quality of life (QOL) score were observed; before and after treatment, the prostate volume (PV) was measured by abdominal ultrasound; and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: Compared before treatment, the scores of IPSS, OABSS and QOL were decreased after 4 weeks of treatment and in follow-up in both groups (P<0.01, P<0.05). In the sacral four-point EA group, the scores of IPSS and QOL after 4 weeks of treatment and in follow-up were lower than those in the conventional EA group (P<0.05, P<0.01), and the OABSS score in follow-up was lower than that in the conventional EA group (P<0.05). After 4 weeks of treatment and in follow-up, the reductions of IPSS and OABSS scores compared before treatment in the sacral four-point EA group were larger than those in the conventional EA group (P<0.01, P<0.05); After 2, 4 weeks of treatment and in follow-up, the reductions of QOL score compared before treatment in the sacral four-point EA group were larger than those in the conventional EA group (P<0.01). No significant difference in PV was observed after treatment between the two groups (P>0.05). The total effective rate was 75.0% (21/28) in the sacral four-point EA group, which was higher than 39.3% (11/28) in the conventional EA group (P<0.01). CONCLUSION EA at "four points of sacral region" can effectively improve the LUTS, overactive bladder symptom and quality of life in patients with mild-to-moderate BPH, and has good short-term and long-term efficacy, although it can not reduce prostate volume.

OBJECTIVE Optimizing the water extraction technology of Xiangqin jiere granules. METHODS The orthogonal test of 3 factors and 3 levels was designed， and comprehensive scoring was conducted for the above indexes by using G1-entropy weight to obtain the optimized water extraction technology of Xiangqin jiere granules with water addition ratio， extraction time and extraction times as factors， using the contents of forsythoside A， baicalin， phillyrin， oroxylin A-7-O-β-D-glycoside， wogonoside， baicalein and wogonin， and extraction rate as evaluation indexes. BP neural network modeling was used to optimize the network model and water extraction process using the results of 9 groups of orthogonal tests as test and training data， the water addition multiple， decocting time and extraction times as input nodes， and the comprehensive score as output nodes. Then the two analysis methods were compared by verification test to find the best water extraction process parameters. RESULTS The water extraction technology optimized by the orthogonal test was 8-fold water， extracting 3 times， extracting for 1 h each time. Comprehensive score was 96.84 （RSD＝0.90%）. The optimal water extraction technology obtained by BP neural network modeling included 12-fold water， extracting 4 times， extracting for 0.5 h each time. The comprehensive score was 92.72 （RSD＝0.77%）， which was slightly lower than that of the orthogonal test. CONCLUSIONS The water extraction technology of Xiangqin jiere granules is optimized successfully in the study， which includes adding 8-fold water， extracting 3 times， and extracting for 1 hour each time.

Objective To evaluate the accuracy of bioelectrical impedance analysis(BIA)in measurement of appendicular skeletal muscle mass(ASM)of adults.Methods A total of 836 adults aged 18-42 years were recruited in Guangzhou using a convenient sampling method from April 2021 to September 2022.ASM was measured using BIA and Dual-energy X-ray absorptiometry(DXA).Using DXA as the standard method,the consistency between the BIA and DXA measurements was evaluated by intra-class correlation coefficients(ICCs)and Bland-Altman analysis in logarithmically transformed data,in order to evaluate the accuracy of BIA in ASM measurement.Receiver operating characteristic curve was plotted to evaluate the diagnostic value of BIA for screening low muscle mass.Results A total of 774 individuals were included for analysis finally.ICCs for ASM measured by BIA and DXA were 0.774 and 0.667 in males and females,respectively.Mean ratios(limits of Agreement)of ASM were 0.94(0.80-1.10)and 0.91(0.78-1.05)in males and females,respectively.Area under curve of BIA for screening low muscle mass were 0.91 and 0.94 in males and females,respectively.The optimal cut-off values of Z-score by BIA for males and females were-0.57 and-0.66,respectively.Sensitivity and specificity for males were 82.5%and 86.0%,while being 86.8%and 93.8%,for females.Conclusion BIA shows a moderate consistency with DXA for measuring ASM in adults.Furthermore,BIA yields a good diagnostic value in identifying low muscle mass in adults aged 18-42 years.

Objective:To investigate the relationship among mental health,maternal negative emotion and mother-child attachment in preschoolers.Methods:A total of 591 mothers of preschoolers from 8 kindergartens were selected.The Preschoolers Mental Health Scale(PMHS)was used to evaluate mental health of the preschool-ers,the Self-rating Depression Scale(SDS)and Self-rating Anxiety Scale(SAS)were used to evaluate maternal negative emotions,and Maternal Object Relationship Scale-Short Form(MORS)was used to evaluate mother-child attachment.Results:The scores of SDS and SAS were positively correlated with the total scoresand scores of each dimension of PMHS(r=0.69-0.93,Ps＜0.001).The maternal SDS and SAS scores were positively associated with total PMHS scores(β=0.38,0.52).The products of maternal SAS scores and MORS scores were negatively associated with the total PMHS scores(β=-0.12).Conclusion:Preschoolers mental health is closely related to a maternal negative emotion and mother-child attachment.

Objective: To investigate the factors influencing parents willingness to vaccinate their children against influenza in Guangzhou, and to provide a scientific basic for effectively improving the coverage rate of influenza vaccine in children. Methods: According to economic level, one secondary school and one elementary school in each of the central administrative and peripheral districts of Guangzhou were selected by stratified cluster sampling. A questionnaire survey was conducted among 5 133 parents of the school students. Questionnaire content included the basic characteristics of children and their parents, and parents knowledge of influenza vaccination for children. Results: A total of 14.57%(748/5 133) of parents were unwilling to have their children vaccinated against influenza. The results of the multivariate Logistic regression analysis found that, compared with parents aged ≤35 years old, parents aged 41-45 years and ≥46 years were 49% (adjusted OR=1.49, 95%CI =1.11-2.00) and 86% (adjusted OR= 1.86 , 95%CI =1.33-2.60), respectively, more likely to refuse vaccinating their children. Parents with an annual income ≥ 200 000 yuan were 52% more likely to be unwilling to vaccinate their children than those with annual income <100 000 yuan (adjusted OR=1.52, 95%CI =1.12-2.06). Parents living within a walking distance ≥30 minutes from the vaccination clinic were 52% more likely to be vaccinereluctant than those living within a walking distance of ≤10 minutes (adjusted OR=1.52, 95%CI = 1.16- 1.99). Compared with parents who regarded the vaccine as safe, parents who did not believe that it was safe or who were unsure of its safety were more likely to refuse vaccinating their children, with adjusted OR(95%CI ) of 12.75(9.44-17.23) and 3.37(2.73- 4.15 ), respectively( P <0.01). Conclusion Parents age, annual income, recognition of the safety of influenza vaccines, and walking distance to the vaccination clinic are associated with parents willingness to vaccinate children against influenza. Hospitals, communities and schools should cooperate to carry out vaccination and popular science propaganda, and arrange vaccination sites rationally to improve the coverage of influenza vaccines.

OBJECTIVE To investigate the effects of total glucosides of paeony （TGP） on enhancing efficacy and reducing toxicity of Tripterygium wilfordii polyglycoside （TWP） in the treatment of eczema. METHODS Totally 50 SD male rats were collected to establish eczema model by sensitizing with 2，4-dinitrofluorobenzene-acetone olive oil solution （volume ratio was 4∶1） on the abdominal area and provoking on the back and ear. Model rats were randomly divided into model group， loratadine group （0.9 mg/kg）， TWP group （9.45 mg/kg）， TGP group （162 mg/kg） and compatibility group （TWP 9.45 mg/kg+TGP 162 mg/kg）， with 10 rats in each group. Other 10 rats were collected to set as normal group. Three days after the first sensitization， administration groups were given relevant medicine intragastrically， and normal group and model group were given constant volume of 0.1% CMC-Na solution intragastrically， once a day， for consecutive 21 d. Twenty-four hours later after the final administration， the general condition of rats in each group was observed， and the eczema area and severity index （EASI） were scored； ear swelling degree of rats was measured， and the skinhistomorphology observation and pathological score were performed； protein expressions of p38 mitogen-activated 13938427612@126.com protein kinase （p38 MAPK）， phosphorylated p38 MAPK （p- MAPK） and phosphorylation level of p38 MAPK in rat skin tissue were detected； the levels of inflammatory indexes （interleukin-4， interferon- γ）， liver and kidney function indexes [glutamic-pyruvic transaminase （GPT）， glutamic-oxaloacetic transaminase （GOT）， serum creatinine （SCr） and blood urea nitrogen （BUN）] and oxidant stress indexes [total superoxide dismutase （T-SOD） and malondialdehyde （MDA）] were measured. RESULTS Compared with normal group， EASI score， ear swelling degree， pathological score， protein expressions of p38 MAPK and p-p38 MAPK， phosphorylation level of p38 MAPK， the levels of inflammatory indexes and BUN were all increased significantly in model group （P＜0.05）. Compared with model group， EASI scores， ear swelling degree， pathological scores， protein expressions of p38 MAPK and p-p38 MAPK， phosphorylation levels of p38 MAPK and levels of inflammatory indexes were all improved significantly in administration groups （P＜0.05）. The levels of GPT， GOT， SCr and BUN were increased significantly in TWP group， while the serum levels of GOT and SCr in TGP group and serum level of SCr in loratadine group were all decreased significantly （P＜0.05）. The levels of T-SOD in liver and kidney tissue were all decreased significantly in TWP group and compatibility group， while the levels of MDA were increased significantly （P＜0.05）. The compatibility group showed more obvious effect in improving the ear swelling degree， pathological score， p38 MAPK expression and its phosphorylation level and levels of inflammatory indexes， and could reverse the abnormality of liver and kidney indexes caused by TWP （P＜0.05）. CONCLUSIONS The combination of TGP and TWP has the effects of anti-inflammatory， synergistic and hepatorenal detoxification in eczema model rats. Its mechanism may be associated with down-regulating the expression of serum proinflammatory indexes and inhibiting the activation of p38 MAPK pathway.

Objective:To explore the correlation between frailty and foot care behavior in elderly patients with high-risk diabetic foot.Methods:From January to June 2022, 220 patients with high-risk diabetic foot who were admitted to the Department of Endocrinology and Department of Geriatrics of Xuanwu Hospital of Capital Medical University were selected by convenience sampling as the research object. The patients were investigated with the General Information Questionnaire, Gavin's Weighted Scale for Diabetic Foot Risk Factors for Progression to Ulceration, the Chinese version of the Frail Scale and the Foot Care Behavior Questionnaire for Diabetic Patients. Spearman correlation analysis was used to explore the correlation between frailty and foot care behavior in elderly patients with high-risk diabetic foot. Multiple linear regression was used to analyze the influencing factors of foot care behavior in elderly patients with high-risk diabetic foot. A total of 220 questionnaires were distributed, and 210 valid questionnaires were collected, with an effective response rate of 95.45% (210/220) .Results:The standardized score of the Foot Care Behavior Questionnaire for Diabetic Patients among 210 elderly patients with high-risk diabetic foot was (56.65±11.27), which was in the middle to low level. Among them, 126 patients (60.00%) were at a low level, and 80 patients (38.10%) were at a middle level. The incidence of frailty in 210 elderly patients with high-risk diabetic foot was 27.14% (57/210). The results of correlation analysis showed that the frailty score of elderly patients with high-risk diabetic foot were negatively correlated with the scores of the foot and footwear examination, foot cleaning and maintenance, footwear selection, and the total score of Foot Care Behavior Questionnaire for Diabetic Patients ( P<0.05). The results of multiple linear regression analysis showed that gender, frailty, foot risk classification and living conditions were the influencing factors of foot care behavior in elderly patients with high-risk diabetic foot ( P<0.05) . Conclusions:The foot care behavior of elderly patients with high-risk diabetic foot needs to be improved. The higher the degree of frailty, the lower the level of foot care behavior. Medical and nursing staff should formulate targeted intervention measures according to the characteristics of patients to improve or delay the progression of patients' frailty, thereby improving their foot care behavior and preventing the occurrence of diabetic foot.
