Objective To evaluate the endometrium receptivity of endometriosis (EMs) infertile patients, and observe the influence of TCM treatment to endometrium receptivity and IVF-ET pregnancy outcome. Methods Fifty EMs infertile patients were randomly divided into two groups. The reatment group (30 cases) kept taking TCM for 3 month continuously before IVF-ET embryo transplantation, and the control group (20 cases) received no treatment, with 30 healthy women as normal control. Using transvaginal color doppler ultrasound to detect and compare the endometrial thickness, endometrium and endometrial blood flow distribution types, and uterine artery blood flow parameters in window transvaginal stage. Results There was no difference in endometrial thickness between the EMs infertility patients and the normal group, and the endometrial thickness also had no obvious changes before and after treatment (P>0.05). RI and PI of EMs infertility patients were significantly increased, compared the with normal control group (P<0.05). In treatment group, the persentage of type Ⅰ blood distribution was 23.33%(7/30), in control group was 25.00%(5/20), and 66.67%(20/30) in the normal group, significantly higher than that of the EMs infertility patients (P<0.01). Uterine artery blood flow parameters RI, PI value were significantly decreased after treatment in treatment group, endometrium and endometrial blood flow type Ⅰ distribution increased to 60.00%(18/30). The rate of normal pregnancy was 46.67% (14/30) in treatment group, and control group was 30.00% (6/20). Conclusion EMs may affect uterine artery hemodynamic status and endometrium receptivity. TCM treatment can improve the endometrium receptivity of EMs infertile patients and improve the success rate of IVF-ET.

Objective:To investigate the clinical application and adverse events of vinpocetine injection. Methods:The application of vinpocetine injection in the patients in neurology department during December 2013 and December 2014 in a hospital was statistically analyzed. The adverse reactions of the injection reported in the professional literatures and relevant documents were also retrieved and statistically analyzed. Results:The infusion concentration of vinpocetine injection for 363 patients was more than 0. 06 mg·ml -1 ,and 3 cases of adverse reactions appeared with the main symptoms of rash and drug fever. Among 28 published literatures,19 articles were with the infusion concentration of vinpocetine injection above 0. 06 mg·ml-1 and 8 articles reported adverse reactions in varying degrees. Conclusion:Clinicians should pay attention to the instructions in the clinical course of medication in order to improve the safe and rational use of drugs.

Objective:To analyze the consistency of HER-2 expression among endoscopic biopsy and radical operation specimens of gastric adenocarcinoma and to investigate the clinical application value of HER-2 detection in trastuzumab treated patients. Methods:From March 2013 to February 2014, 167 patients from Shanghai Changhai Hospital were diagnosed with gastric adenocarcinoma using endoscopic biopsy specimens. The corresponding surgical specimens were collected for pathological analysis. The relevant clinical and pathological data were collected. HER-2 protein expression of endoscopic biopsy specimens was detected by immunohistochemistry (IHC). HER-2 protein expression and gene amplification status of the corresponding tumor resection specimens were detected by IHC and fluorescence in situ hybridization (FISH). Results were analyzed for clinicopathological characteristics. Results:Among the 167 cas-es, 18 cases (10.8%) were HER-2 positive, including 10 cases showing IHC3+and 8 cases showing IHC2+with FISH positive. The consis-tency rate result among endoscopic biopsy and surgical operation specimens was 82%. Excluding the cases showing IHC2+, the true positive rate and the true negative rate were 73.3%and 97.0%, respectively. Conclusion:HER-2 detection of endoscopic biopsy speci-men by IHC shows great predictive value. The main reason for the difference of surgery and biopsy specimens is the heterogeneity of tumor expression. Increasing the number of specimens and combined testing with FISH are important methods to reduce misjudge-ment.

Objective: To investigate whether Vigconic VI-28 capsule, a formulated traditional Chinese medicine containing radix Ginseng, cornu cervi pantotrichum and semen cuscutae, can assist tumor chemotherapy in a mouse model. Methods: Female C57BL/6 mice were s. c. injected with viable Lewis lung cancer ( LLC) cells (106 cells/mouse) . The mice were then treated with cyclosposphamide (Cyp, 40 mg/kg bodyweight, once every other day). One group was intra-gastrically given 2% VI-28 (0.5 ml/mouse, every other day) during the course of the chemotherapy. By day 28, the mice were sacrificed and their thymic indices and tumor indices were calculated and compared. Splenocytes were collected for analysis of their immunological status. Histological study was carried to examine the solid tumors. Results: Fourteen days after the injection of LLC cells, solid tumors developed in most of the animals, reaching 1 ~ 1.8 cm diameters by 28 th day Compared with mice of the LCC + Cyp group, thymus glands from the LLC + Cyp + VI-28 group were significantly heavier. Splenocytes of the same group responded better to ConA stimulation in vitro. Histochemical examination of the tumor tissues revealed that tumors of the Cyp + VI-28 group were better differentiated (less aggressive) than that of the Cyp group. Conclusion: Vigconic VI-28 capsule can promote recovery of immune system in mice undergoing chemotherapy and help Cyp to control the growth of tumor cells in vivo.

Purpose To explore the effect of Levothyroxine on spatial working memory in patients with subclinical hypothyroidism (SCH) using blood oxygenation level dependent-functional MRI (BOLD-fMRI). Materials and Methods Sixteen patients with SCH before and after 6 months levothyroxine (LT4) treatment and 16 matched euthyroid volunteers underwent n-back task fMRI scanning. AFNI software was used for localization and quantification. Results All the subjects demonstrated activated areas including bilateral dorsolateral prefrontal cortex (DLPFC), bilateral premotor area (PreMA), supplementary motor area/anterior cingulate cortex, bilateral parietal area (PA) and right caudate nucleus/thalamus, with right hemisphere dominance. Quantitative analysis of regions of interests showed that all these regions had load effect related to memory load in the control group (P<0.001), whereas only left DLPFC, left PA, bilateral PreMA and right caudate nucleus/thalamus showed the same effect in SCH group. After 6-month treatment with LT4, BOLD signal change was observed in SCH patients within the right DLPFC, right PA and anterior cingulate/supplementary motor cortex (P<0.001). The activation intensity of working memory related brain regions was lower in SCH group compared with that of the control group. Conclusion Spatial working memory impairments in SCH patients are likely related to decreased right DLPFC and right posterior parietal function. LT4 replacement therapy is important to improve and reverse the memory impairment.
