Journal of Chinese Physician 2009;11(7):917-918
Objective To investigate the expression of COX-2, VEGF, MMP-2 and P-g]ycoprotein in carcinoma of stomach and its significance. Method The expressions of COX-2, VEGF and P-glycoprotein inside and beside the tumor tissues of 57 cases carcinoma of stomach were detected with immunohistochemistry method. Result The expressions of COX-2, VEGF, MMP-2 and P-glyeoprotein inside the tumor tissues were significantly higher than that beside the tumor(χ2 = 5.29,5.37,5.62,4.87 ; P < 0.05). The expressions of COX-2, VEGF and MMP-2 were different among different carcinoma metastasis (χ2 = 5.97, 6.17,6.09 ; P < 0.05). P-glucoprotein expressions were positive correlated with gastric cancer(rs' = 0.674,0.65,0.67 ; P < 0.05). Conclusion COX-2, VGEF, MMP-2 and P-glyeopretein were some correlated and overexpressed in stomach carcinoma, which may take part in the genesis, development and multi-drug resistance of this cancer.

Objective To explore the correlations between the levels of serum 25 ( OH) D and age, blood sugar, blood lipid, blood pressure and insulin levels in patients with subcortical arteriosclerotic encephalopathy . Methods A total of 100 patientswith subcortical arteriosclerotic encephalopathy ( SAE) and 50 healthy persons were enrolled in the study.ELISA was adopted to determine serum 25(OH)D levels in two groups.Meantime, fasting glu-cose, blood lipid, blood pressure and insulin levels were measured and compared between two groups .Results The systolic blood pressure , diastolic blood pressure , fasting glucose , total cholesterol and insulin levels in SAE patients were significantly higher than those in the healthy control (p<0.05).The serum 25(OH)D levels in SAE patients were significantly lower than that in the healthy control (p<0.01).There were no significant differences in triglycer-ide and lipoprotein between two groups (p>0.05).The serum 25(OH)D levelswere negatively related with age, SBP, DBP and fasting glucose(p<0.05,p<0.01) but not correlative with TC, TG, LDL, HDL, and insulin levels in SAE patients.Conclusion The serum 25(OH)D levels in SAE patients are reducedby playing a regulative role in the occurrence and development of SAE throughaffectingthe energy metabolism .

ObjectiveTo compare therapeutic effects of the bone-guided tissue regeneration in combination with a composite bovine-derived xenograft versus flap surgery only on intra-bony defects in elderly patients with periodontal disease. MethodsThirty elderly patients with periodontal disease were randomly divided into two groups. One group was treated by the bone-guided tissue regeneration in combination with a composite bovine-derived xenograft (experimental group). The other group was treated by flap surgery only (control group). Probing depth (PD)and clinical attachment level (AL) were determined before surgery and six months after treatment in two groups. The change of bone amount was also determined before surgery and six months after treatment through computer-assisted densitometric image analysis(CADIA). ResultsThe changes of PD and CADIA were (3.8+1.7)mm, (20. 3+11.1)g/mm2 in experimental group and were (2.5+1.1)mm, (9.4+8. 6)g/mm2 in control group. The differences between two groups were significant (P.<0. 05). The change of AL was (3.5+ 1.6)mm in experimental group, compared with control group(2. 3 1.7)mm, which showed more obvious regeneration of alveolar bone (P< 0. 01). ConclusionsGuided tissue regeneration in combination with a composite bovine-derived xenograft appears to be more effective than flap surgery only for intra-bony defects in elderly patients with periodontal disease.

7.Single cell RNA sequencing technology applicated for drug discovery
Acta Pharmaceutica Sinica 2023;58(9):2551-2559
Single cell RNA sequencing (scRNA-seq) is an advanced technology to study the transcriptome information at the single cell level. The application of this technology can attribute to analyze the heterogeneous map of cells in the process of disease development, and precisely identify the specific cell subsets that are responsive to pharmacological therapy. Currently, scRNA-seq technology has been widely applied in the field of drug research, including studies on therapeutic targets, drug-induced adverse reactions, drug resistance and vaccine. This work reviews the application of scRNA-seq technology in drug discovery, which offers a scientific basis for personalized and accurate medication therapy.

Partial deletion of the long arm of chromosome 7 is a rare disease and is prone to missing the diagnosis or being misdiagnosed.Here we present a case of a 13-year-old boy that showed symptoms such as growth-retardation,moderate intellectual disability,hypotelorism,microcephaly,epicanthal folds,genu varum and lumbar vertebral cleft,but it did not show serious symptoms like cleft lip,urogenital malformation and hypotonia.He was eventually diagnosed as partial deletion of the long arm of chromosome 7 syndrome through gene analysis.Considering the rare incidence of this disease and more rarely for being hospitalized to endocrine ward due to growth retardation,this case report can provide more information for clinic diagnosis and differential diagnosis for growth retardation.

OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.
METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.
RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).
CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.

Objective To discuss the ultrasound imaging of acardia twin before and after spontaneously blood blocked in twin reversed arterial perfusion sequence (TRAP), and to analyze the inlfuence factor for the prognosis of pump twin. Methods Seven TRAP with pump twins and acardia′s blood lfow blocked were diagnosed by US and autopsy in Hubei Women and Children′s Hospital between 2001 January to 2012 September. The ultrasound images, clinical data and pump twin’ outcome were analyzed. Results Ultrasound images showed skin edema, acardia, spine and lower limbs in seven acardia cases before blood blocked, among which 4 were acardius acephalus, 3 were acardius anceps. Single umbilical artery were detected in 7 cases with reversed umbilical artery perfusion toward fetus. Four cases had rare blood lfow (UA-PI ratio<0.7. Five acardia cases had slower growing rate than the pump twin. Ultrasound images showed no growing, no blood lfow in the acardia, the acardia twin became vagued in the second and third trimester, and ifnally developed into a paper fetus. A linear umbilical cord extend from umbilical region to placenta were found in 7 cases whose blood lfow were spontaneously blocked. Pump twin′s outcome:3 pump twins survived, 3 died in uterus, and 1 was induced labor due to hydrocephalus and cardiac failure. The most important factors that affected the prognosis of pump twin included:faster growing in acardia twin with less blood supply, abnormal brain and heart function in pump twin, chromosome abnormalities, abnormal amniotic fluid and cord entanglement. Conclusions Less blood flow and slow growth speed prompt in acardia twin suggested spontaneously acardia blood block. It is mandatory to monitor the pump twin after the spontaneous block of acardiac’s blood lfow.
