Objective To make an epidemiological investigation on traditional Chinese medicine(TCM)dampness syndrome manifestations in the population at risk of cerebrovascular diseases in Guangdong area.Methods A cross-sectional study was conducted to analyze the clinical data related to the risk of cerebrovascular diseases in 330 Guangdong permanent residents.The diagnosis of dampness syndrome,quantitative scoring of dampness syndrome and rating of the risk of stroke were performed for the investigation of the distribution pattern of dampness syndrome and its influencing factors.Results(1)A total of 306(92.73%)study subjects were diagnosed as dampness syndrome.The percentage of dampness syndrome in the risk group was 93.82%(258/275),which was slightly higher than that of the healthy group(48/55,87.27%),but the difference was not statistically significant(χ2 = 2.91,P = 0.112).The quantitative score of dampness syndrome in the risk group was higher than that of the healthy group,and the difference was statistically significance(Z =-2.24,P = 0.025).(2)Among the study subjects at risk of cerebrovascular disease,evaluation time(χ2 = 26.11,P = 0.001),stroke risk grading(χ2= 8.85,P = 0.031),and history of stroke or transient ischemic attack(TIA)(χ2 = 9.28,P = 0.015)were the factors influencing the grading of dampness syndrome in the population at risk of cerebrovascular disease.Conclusion Dampness syndrome is the common TCM syndrome in the population of Guangdong area.The manifestations of dampness syndrome are more obvious in the population with risk factors of cerebrovascular disease,especially in the population at high risk of stroke,and in the population with a history of stroke or TIA.The assessment and intervention of dampness syndrome should be taken into account for future project of stroke prevention in Guangdong.

Endometriosis is a chronic,relapsing disease that requires long-term management.Ado-lescent endometriosis is a group that can be ig-nored,and the drug treatment is an important method for long-term management and fertility preservation.There are many kinds of drugs to treat endometriosis,such as NSAIDs,combined oral contraceptives(COC),progesterone,GnRHa.For the drug treatment selection,the characteris-tics of adolescents should be carefully considered and individualized treatment should be provided.In order to better long-term management,it is nec-essary to develop new treatments,which can effec-tively relieve endometriosis without damaging fer-tility.This review focuses on the drug treatment op-tions and research progress of basic drug treat-ment for adolescent endometriosis,so as to delay disease progression,reduce adverse reactions,pre-serve fertility,and improve quality of life.

Objective To investigate the characteristics of gut flora related to dampness syndrome in the population at risk of cerebrovascular disease and to explore their influencing factors.Methods Based on the results of epidemiological investigation of damp syndrome in at-risk population of cerebrovascular disease in Guangdong from October 2021 to February 2023,60 subjects(including 41 at-risk cases of cerebrovascular disease and 19 healthy controls)were included in the study.The identification of dampness syndrome and the risk rating of stroke were carried out for the subjects,and fecal samples were collected.High-throughput 16S rRNA sequencing technology and bioinformatics methods were used to analyze the characteristics of gut flora.Results(1)A total of 53 cases(88.33％)were identified as dampness syndrome.There was significant difference in the quantitative score of dampness syndrome between the risk group and the healthy group,and between the low-,medium-and high-risk groups(P=0.016;P=0.041).(2)There was no statistical difference in the species and abundance of gut flora between the dampness syndrome group and the non-dampness syndrome group.(3)In the population identified as dampness syndrome,there was no significant difference in Alpha diversity between the healthy group and the risk group,but there was significant difference in Beta diversity analysis;LEfSe analysis found that Fusobacterium and Lactobacillus were enriched in the risk group;correlation analysis showed that the differential bacteria were related to the three risk factors of diabetes,dyslipidemia and obesity and carotid intima-media thickness(IMT).(4)In the population identified as dampness syndrome and having the risk of cerebrovascular disease,there was no significant difference in Alpha diversity among three groups with different levels of risks,while significant difference in Beta diversity was observed;LEfSe analysis showed that Acidaminococcaceae,Phascolarctobacterium and Butyricimonas were enriched in the low-risk group,Veillonellaceae was enriched in the medium-risk group,and Ruminococcus 2 and Alloprevotella were enriched in the high-risk group;correlation analysis showed that the differential bacteria were associated with high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),white blood cell count(WBC),and neutrophil count(NEUT).Conclusion In the Guangdong population predominated by dampness syndrome,the severity of dampness syndrome is related to the risk of stroke,and the specific flora associated with sub-clinical atherosclerosis,inflammatory response and lipid metabolism are presented.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Objective: To evaluate the effect of multidisciplinary cooperative pain management on the rapid recovery of patients with total hip and total knee arthroplasty. Methods: A total of 120 patients, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 20-64 yr, with body mass index of 18-25 kg/m², were divided into 2 groups using a random number table method: test group (group T, n=66) and control group (group C, n=54). Multidisciplinary cooperative pain management mode was adopted for pain management in the perioperative period in group T, while traditional pain management was used in group C. Numeric rating scale scores were recorded at 4 h and 1, 2, 3 and 7 days after surgery and on discharge from hospital.The postoperative joint recovery time, length of hospital stay and satisfaction were recorded in two groups. Results: Compared with group C, the numeric rating scale scores were significantly decreased at 4 h and 1, 2, 3 and 7 days after surgery and on discharge from hospital, the postoperative joint recovery time and length of hospitalization were shortened, and the degree of satisfaction was increased in group T (P<0.05). Conclusion Multidisciplinary cooperative pain management can effectively promote the rapid recovery of patients with total hip and total knee replacement.

OBJECTIVE: To investigate the expression of microRNA-622(miR-622)in epithelial ovarian cancer,andanalyze its influence on tumor cell migration and invasion.METHODS:Epithelial ovarian cancer(n=125),benignepithelial ovarian tumors(n=45),and normal ovarian tissues(n=25)were obtained from January 2003 to December 2016 at Dongguan People's Hospital of Southern Medical University.The expression of miR-622 was determined by real-timePCR.The miR-622 mimics were transiently transfected into human ovarian cancer cells,and their influence on cellmigration and invasion was analyzed by Transwell assay.RESULTS:Higher miR-622 expression was found in epithelialovarian cancer tissues than in benign epithelial ovarian tumors and normal ovarian tissues(P<0.05).Expression of miR-622 was correlated with FIGO stage and lymphatic metastasis(P<0.05).Up-regulation of miR-622 promoted theinvasion and migration of SKOV3 cells in vitro.CONCLUSION:The expression level of miR-622 is increased in tumourtissues,which indicates that miR-622 might be involved in the progression of epithelial ovarian cancer by promotingcancer cell migration and invasion.

Objective: To compare the efifcacy of direct and pre-dilated atherectomy (RA) for treating the patients with calciifed coronary lesions. Methods: A total of 137 coronary artery disease (CAD) patients received RA treatment in our hospital from 2010-04 to 2014-09 were retrospectively studied. The ischemic related lesions were all deifned as calciifed coronary lesions. The patients were divided into 2 groups: Direct RA group,n=81 and Pre-dilated RA group, the patients received balloon dilatation followed by RA,n=56. The procedural features, complications, in-hospital and 1 year occurrence rates of major cardiaccerebral vascular events (MACCE) were compared between 2 groups. Results: Compared with Pre-dilated RA group, Direct RA group had the less pre-stent balloon application,P=0.000 and the higher maximum post-dilatationpressure,P=0.004; lower rate of in-operative complication (14.8% vs 32.1%),P=0.016; higher rate of acute lumen gain (128.52±75.77) % vs (77.12±27.01) %,P=0.004; lower MACCE occurrencerate(7.3% vs 23.6%) at 1 year period,P=0.006.Cox regression analysis presented that the following indexes were related to MACCE occurrence within 1 year of RA treatment: balloon dilatation before RA (HR=8.166, 95% CI 1.872-35.614,P=0.005), left main disease (HR=13.649, 95% CI 2.983-62.440,P=0.001), minimum post-operative lumen area (HR=0.583, 95% CI 0.378-0.879,P=0.010), post-dilatation (HR=0.066, 95% CI 0.013-0.332,P=0.001) and EF>40% (HR=0.019, 95% CI 0.002-0.158, P=0.000). Conclusion: Direct RA had the lower MACCE occurrence rate at 1 year period, this might be related to less operative complication and the optimal lumen gain.
