Chinese Journal of Biologicals 2023;36(3):281-
ObjectiveTo explore the protective effect of Sox11 gene on cerebral ischemia reperfusion injury(CIRI)in mice and its mechanism,so as to provide a new target for the treatment of CIRI.MethodsThe mouse middle cerebral artery occlusion(MCAO)model and Neuro2A cell oxygen glucose deprivation reperfusion(OGDR)model were established and detected for the temporal and spatial distribution of Sox11 in the models by real-time quantitative PCR,Western blot,immunohistochemistry(IHC)and immunohistofluorescence(IHF).The altered expression of some crucial genes in the pathway of apoptosis and inflammation in OGDR model after the disruption of Sox11 expression was detected by Western blot.ResultsThe expression level of Sox11 mRNA and protein increased significantly in both MCAO and Neuro2A OGDR models(P = 0.000 1 ~ 0.038 8);After CIRI,Sox11 expression was elevated in the hippocampal dentate gyrus(DG)region of mice;After interfering with the expression of Sox11 in OGDR model,the expression of apoptosis-related protein Cleaved Caspase 3 significantly increased,while the expression of anti-apoptosis protein Bcl-2 significantly decreased,and the expression of phosphorylated NF-κB(p-NF-κB)protein related to inflammatory reaction also up-regulated significantly.Conclusion Sox11gene had a protective effect against CIRI in mice,and was involved in the regulation of apoptosis and inflammation pathways after CIRI.

Objective To establish a new and convenient assay for whole blood lead concentration. Methods Whole blood sample was digested by nitric acid-perchloric. Under the condition of pH 0.8~1.0, lead concentration was examined by Hydridegeneration Atomic Fluorescence Spectrometry.Results The method had good linearity when lead concentration were between 0 to 600 ?g/L, r =0.999. The within-run CV of the method for high, middle and low lead level were 4.1%, 3.6% and 3.5% respectively. The between-run CV were 4.9%, 4.6% and 4.7% respectively. The recovery rates were 105.4%, 98.5% and 94.8% respectively. The single-blind test result of series standard lead samples provided by Chinese Academy of Preventive Medicine were within the acceptable range. The detecting Limit of this method was 0.3 ng. There was no significant interference from main two-valence positiveion. The sample can be storage at lest for 1 months at 4℃. Samples of 869 children from Tianjin were tested by this method. The mean value was 91.9 ?g/L, median was 83.8 ?g/L, all data were within 23.1~386.3 ?g/L. The result showed out positive skewness distribution.Conclusion This method were sensitive, accurate, precise, quick and low-cost. It was suitable for use in clinical laboratories.

Objective To study the clinical and pathological features, diagnosis and treatment of malig-nant mesothelioma of the tunica vaginalis testis. Methods One case of malignant mesothelioma of the tuni-ca vaginalis testis was reported. The patient was a 73 years old man, presented with a history of aggravated hydrocele for 1 year. B-ultrasound showed 7.5 cm×4.1 cm liquid anechoic area around the testis. The Pubmed and CBM databases were searched for related articles, and the clinical data were reviewed. Results An operation was performed to incise the tunica vaginalis. The pathology showed fecal caneeration in the tunica vaginalis testis and the immunohistology showed CK5/6, Calretinin and E-cadlberin positive. Right or-chiectomy was performed after three weeks. Local tumor recurrence and inguinal lymph nodes metastasis were found 11 months after operation, and local tumor and lymph nodes were resected. The tumor was diagnosed as malignant mesothelioma of the tunica vaginalis testis and CK5/6 and Calretinin fecal positive. Conclu-sions Malignant mesothelioma of the tunica vaginalis is a rare disease of the testis with potentially aggres-sive behavior. Due to the lack of tumor markers and characteristic symptoms, correct preoperative diagnosis is extremely difficult. Radical surgical treatment is of major importance to the survival of the patients. Life-long follow-up should be offered to patients with malignant mesothelioma of the tunica vaginalis.

Objective To explore the medication rules of Professor WEI Pin-kang in treating gastric cancer; To provide references for clinical medication. Methods Gastric cancer cases treated by Professor WEI Pin-kang in TCM outpatient department of Shanghai Changzheng Hospital from January 2008 to December 2015 in WEI Pin-kang TCM Studio Outpatient Medical Cases (including electronic database and paper medical cases database). TCM Inheritance Support System V2.5 was used to build database. Frequency analysis, association rule analysis, complex system entropy clustering and other data mining methods were used to analyze frequency, medicine association rules and core medicine combination. Results Totally 305 clinical prescriptions including 185 kinds of Chinese materia medica were collected. The Chinese meteria medica with the high frequency were Pinellinae Rhizoma Praeparatum, Arisaematis Rhizoma Preparatum and Galli Gigerii Endothelium Corneum, etc. High frequency Chinese materia medica were with the properties of warm and cold, and with the flavors of bitter, spicy and sweet, to Stomach Meridian of Foot-Yangming, Spleen Meridian of Foot-Taiyin, and Liver Meridian of Foot-Jueyin. The medicine combinations with high frequency were Pinellinae Rhizoma Praeparatum and Arisaematis Rhizoma Preparatum,Pinellinae Rhizoma Praeparatum and Galli Gigerii Endothelium Corneum, and Galli Gigerii Endothelium Corneum and Arisaematis Rhizoma Preparatum. The common medicine pairs were Aurantii Fructus and Aurantii Fructus Immaturum and Scorpio and Scolopendra. Analysis showed 36 association rules of the confidence > 0.99. 70 core medicine combinations and 11 new prescription were obtained. Conclusion Professor WEI Pin-kang treats gastric cancer based on phlegm theory. The dissolving phlegm and eliminating stagnation medicine, regulating qi-folwing for harmonizing stomach medicine and heat-clearing and detoxifying medicine are commonly used.
