ObjectiveThe mechanisms underlying therapeutic efficacies of Detumescence Analgesic Plaster was analyzed based on "effect-target" associations. MethodBased on CNKI and PubMed databases， the chemical components of Artemisia seed， bastard speedwell， and menthol in Detumescence Analgesic Plaster were collected. The capacity of transdermal absorption was predicted based on the Encyclopedia of Traditional Chinese Medicine （ETCM 2.0）. Golden Triangle of compounds with Accepted used for candidate target prediction based on the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP v2.0）according to the similarity of chemical structures. At the same time， the SoFDA data platform was employed to collect the symptoms related to the efficacy of Detumescence Analgesic Plaster and its related genes information. In addition， based on the interaction between the above-mentioned candidate targets and their efficacy-related genes， the "effect-target" interaction network of Detumescence Analgesic Plaster was constructed. The key targets by topological features calculation， and functional mining was carried out to explain the efficacy mechanism of Detumescence Analgesic Plaster. ResultA total of 165 candidate targets were obtained based on ETCM 2.0 and TCMIP v2.0 databases， and symptoms related to the efficacy of clearing heat， detumescence， and relieving pain， as well as 1 744 related genes were collected based on the SoFDA database. Network construction and analysis showed that the core effect targets of Detumescence Analgesic Plaster were mainly involved in regulating the "immune-inflammation" balance of the body and maintaining the homeostasis of material and energy metabolism， blood circulation， and nervous system functions， and they were closely related to the efficacy of this prescription in clearing heat， reducing detumescence， and relieving pain. Among them， the heat clearing group of Detumescence Analgesic Plaster had the functions of heat clearing， detoxifying， antibacteria， and anti-inflammation. The biological function of its key effect target group was related to correcting the imbalance of "immune-inflammation" induced by pathogens. The detumescence group of Detumescence Analgesic Plaster had the functions of reducing water and swelling and resolving hard lumps， and the biological function of its core effect target group was related to improving microcirculation disturbance. The pain relieving group of Detumescence Analgesic Plaster had the functions of removing stasis， promoting blood circulation， and relieving pain， and its core effect target group was related to correcting the nervous system and the disorder of material and energy metabolism. ConclusionThe heat clearing， swelling reducing， and pain relieving effects of Detumescence Analgesic Plaster may be closely related to its act on related candidate targets， so as to correct the imbalance of "nerve-immunity-vascular-axis"， regulate neuronal excitability and inflammatory response， and intervene in material and energy metabolism. The relevant research results lay a theoretical foundation for clarifying the advantages of Detumescence Analgesic Plaster and assisting its clinical precise positioning.

Pathological vascular remodeling is a hallmark of various vascular diseases. Previous research has established the significance of andrographolide in maintaining gastric vascular homeostasis and its pivotal role in modulating endothelial barrier dysfunction, which leads to pathological vascular remodeling. Potassium dehydroandrographolide succinate (PDA), a derivative of andrographolide, has been clinically utilized in the treatment of inflammatory diseases precipitated by viral infections. This study investigates the potential of PDA in regulating pathological vascular remodeling. The effect of PDA on vascular remodeling was assessed through the complete ligation of the carotid artery in C57BL/6 mice. Experimental approaches, including rat aortic primary smooth muscle cell culture, flow cytometry, bromodeoxyuridine (BrdU) incorporation assay, Boyden chamber cell migration assay, spheroid sprouting assay, and Matrigel-based tube formation assay, were employed to evaluate the influence of PDA on the proliferation and motility of smooth muscle cells (SMCs). Molecular docking simulations and co-immunoprecipitation assays were conducted to examine protein interactions. The results revealed that PDA exacerbates vascular injury-induced pathological remodeling, as evidenced by enhanced neointima formation. PDA treatment significantly increased the proliferation and migration of SMCs. Further mechanistic studies disclosed that PDA upregulated myeloid differentiation factor 88 (MyD88) expression in SMCs and interacted with T-cadherin (CDH13). This interaction augmented proliferation, migration, and extracellular matrix deposition, culminating in pathological vascular remodeling. Our findings underscore the critical role of PDA in the regulation of pathological vascular remodeling, mediated through the MyD88/CDH13 signaling pathway.

Objective To explore the genetic etiology of a child with autism,mental retardation and epilepsy.Methods Conventional G-banding chromosomal analysis was carried out.Chromosomal variation was also detected by single nucleotide polymorphism microarray (SNP array).Pathogenic mutations were screened by high-throughput sequencing and validated by Sanger sequencing.Pathologic significance of the candidate mutations was analyzed through search of database and literature review.Results No karyotypic abnormality was found with the child and his parents,while SNP array has detected a 460 kb deletion in the 14q11.2 region in the child.High-throughput and Sanger sequencing revealed a novel mutation of the NALCN gene in the child,in addition with a hemizygous mutation of the COL4A5 gene in the child and his mother.Conclusion The 14q11.2 microdeletion and NALCN mutation may contribute to the autism,mental retardation and epilepsy in this child.

OBJECTIVE: The aim of this study was to investigate voluntary wheel running behavior in the unilateral 6-hydroxydopamine (6-OHDA) rat model. METHODS: Male Sprague-Dawley rats were assigned to 2 groups : 6-OHDA group (n=17) and control group (n=8). The unilateral 6-OHDA rat model was induced by injection of 6-OHDA into unilateral medial forebrain bundle using a stereotaxic instrument. Voluntary wheel running activity was assessed per day in successfully lesioned rats (n=10) and control rats. Each behavioral test lasted an hour. The following parameters were investigated during behavioral tests : the number of running bouts, the distance moved in the wheel, average peak speed in running bouts and average duration from the running start to the peak speed. RESULTS: The number of running bouts and the distance moved in the wheel were significantly decreased in successfully lesioned rats compared with control rats. In addition, average peak speed in running bouts was decreased, and average duration from the running start to the peak speed was increased in lesioned animals, which might indicate motor deficits in these rats. These behavioral changes were still observed 42 days after lesion. CONCLUSION: Voluntary wheel running behavior is impaired in the unilateral 6-OHDA rat model and may represent a useful tool to quantify motor deficits in this model.

Objective To investigate factors that correlated to compliance of treatment in infertile patients with polycystic ovary syndrome (PCOS) to provide basis for clinical treatment, specialist consultation and health education. Methods Compliance was assessed by a questionnaire designed by reference to Morisky-Green test and therapeutic principles for PCOS. Interviews were performed in 128 infertile patients with PCOS in Renmin Hospital of Wuhan University, Wuhan, Hubei in China during March 2009 to September 2010. Data were analyzed with logistic regression. Results Logistic regression analysis revealed that a total of 41 (34.2% ) of 120 participants investigated showed good compliance. Factors that might significantly (P ＜ 0.05 ) correlate compliance of treatment included body mass index (BMI) of the patients ( OR = 2.426, 95% CI = 1.428 - 4.121 ), length of their marriage ( OR = 0.398, 95% CI =0.225 - 0.704) and their concerns for adverse drug reactions ( OR= 0.216, 95% CI = 0.067 - 0.694).Conclusions Patients with obesity, shorter length of marriage and concerns for adverse drug reactions show lower compliance. Publicity and intervention to those patients should be strengthened in clinics to improve their treatment compliance in patients with PCOS.

One hundred and twenty-two infertile women with polycystic ovary syndrome (PCOS) and 112 infertile women without PCOS were interviewed with symptom checklist 90 ( SCL-90) and questionnaire of demographic and clinical characteristics to understand their psychological health status. Results demonstrated that scores of depression, interpersonal sensitivity, obsessive-compulsive and aggressive symptoms in infertile patients with PCOS were significantly higher than those in non-PCOS infertile ones (P < 0. 05 ). Acne had negative effect on their psychological health status (OR =3. 379, 95% CI = 1.096 ±10.419) . Scores of somzatization, interpersonal sensitivity, anxiety, obsessive-compulsive, aggressive and paranoid ideation symptoms were significantly higher in secondary infertile patients with PCOS than those in primary infertile ones (P<0. 05). Patients with PCOS had obviously psychological problems, especially in secondary infertile patients with PCOS ( P < 0. 05 ). Thus, it is suggested that psychological health status be evaluated in clinical diagnosis for infertile women so that they can be predicted and treated to improve its effectiveness.

This study examined the impact of luteinized unruptured follicle (LUF) on endometrial receptivity. The menstrual cycle of 17 LUF patients (LUF group) and 13 ovulatory women (control group) was monitored by measuring LH level in urine and by ultrasonic examination. An endometrial biopsy at the sixth to tenth day after LH surge was taken in all the patients. The expressions of endometrial ER, PR and integrin ανβ3 were immunohistochemically determined. At the same time, the serum levels of E(2) and P were detected by chemiluminescence. The results exhibited that (1) The mean serum P level in LUF group (7.32±2.56 ng/mL) was significantly lower than that in control group (11.17±3.17 ng/mL) (P<0.01). But there was no significant difference in the mean serum E2 levels between LUF group (179.35±81.60 pg/mL) and the control group (198.58±75.23 pg/mL) (P>0.05); (2) The mean expression intensities of ER, PR in endometrium of LUF group (183.86±2.43, 167.94±3.04) were significantly higher than those in control group (109.35±6.31, 105.98±4.07) (P<0.01); (3) The mean expression intensities of integrin ανβ3 in endomtrium of LUF patients (114.90±11.38) were significantly lower than those in control group (191.34±1.82) (P<0.01); (4) The change profile of integrin ανβ3 expression in the endometrium of LUF patients was in positive relation with serum P level (r=0.77, P<0.01), but bore no significant relationship with serum E(2) level (r=0.01, P>0.05). It was concluded that the depression of serum P levels in LUF patients was closely related to the failure of the down-regulation of ER and PR, and the low expressions of integrin ανβ3 also suggested that the delayed implantation and the impaired endometrial receptivity had impact on embryonic implantation.
