Objective To observe the effect of "Jingu Tongxiao Wan" on blood stasis and cold coagulation type gonarthrosis.Methods 160 patients with blood stasis and cold coagulation type gonarthrosis were divided into the "Jingu Tongxiao Wan" group(group A)with 120 cases(treated with "Jingu Tongxiao Wan" 6 g/time,2 times/d)and "Guci Pian" group(group B)with 40 cases(treated with "Guci Pian" 3 tablets/time,3 times/d).Indexes of effect and safe were observed after one month.Results 23 cases were healed,63 cases were excellent,9 cases were utilitied,9 cases were invalid,total effective rate was 93.8% in the group A.While,in the group B,7 cases were healed,21 cases were excellent,9 cases were utilitied,3 cases were invalid,total effective rate was 92.5%.There was no significant difference between two groups(P>0.05).Scores of sings and symptoms before and after treatment were 8.98±2.24 and 2.15±1.71 respectively in the group A,and 8.29±2.35 and 2.25±1.25 respectively in the group B.The scores after treatment were significantly different from that before treatment in each group(P<0.01),and no significant difference between scores of the group A and group B after treatment(P>0.05).Conclusion The treatment of "Jingu Tongxiao Wan" shows an obvious effect and safe on blood stasis and cold coagulation type gonarthrosis.

Objective To observe the inhibitive effect of electro-acupuncture (EA)at Zusanli points (ST36)on inflammatory mediators of postoperative intra-abdominal adhesions and study the relationship between EA and cholinergic anti-inflammatory pathway.Methods Forty-eight male Wistar rats were divided into 6 groups (each =8):Group A (control),Group B(abdominal adhesions model),Group C (abdominal adhesions plus EA),Group D(sham acu-point control),Group E (abdominal adhesions plus α-bungarotoxin )and Group F (abdominal adhesions plus EA after α-bungarotoxin).Animal models of abdominal adhesion were produced by Chiang’s path.Bilateral Zusanli points (ST36) and shame acupoints were electro-acupunctured at a constant voltage for 1 hour while rats were awake.The ɑ-BGT(1 μg/kg)was injected into the abdominal cavity after surgery.All the rats were sacrificed on the 3rd day,and the levels of inflammatory mediators (TNF-ɑ,NO and NOS)in tissues were evaluated.Results Three days after surgery,the damaged cecum of abdominal adhesion groups developed obvious edema that did not adhere with other tissues.Compared with sham control,the abdominal adhesion resulted in significant elevation of inflammatory mediators (TNF-ɑ,NO and NOS).EA at Zusanli points obviously lowered the elevated levels of inflammatory mediators (P <0.01 and P <0.05).EA at Zusanli points following the injection of ɑ-BGT showed less anti-inflammatory effect(P <0.01).Conclusion EA at Zusanli points significantly lowers the elevated levels of inflammatory mediators after abdominal adhesion challenge.The activation of cholinergic anti-inflammatory pathway might be one of the mechanisms by which Zusanli points exert anti-inflammatory effects.

Bilingnal teaching has been practiced to undergraduate eduction at medical university.At the initial period,the bilingual teaching to undergraduate.eduction is not so acceptable for lack of the experionce,textbooks and insufficient commnication between teachers and students.This paper discussed the benefits and applience of bilinqual teahing to undergraduate eduction at ncedica university.

AIM:To investigate the role of microRNA-486-5p (miR-486-5p) in the apoptosis of human bone marrow mesenchymal stem cells (hMSCs) induced by hydrogen peroxide (H2O2).METHODS: The hMSCs were cul-tured in vitro and exposed to serum-free medium and H2O2(10 mmol/L).The changes of miR-486-5p expression in oxida-tive stress-related apoptosis of hMSCs were measured by real-time PCR.The hMSCs were transfected with miR-486-5p mimic or inhibitor at concentration of 30 nmol/L by Lipofectamine RNAiMAX.The effect of miR-486-5p on H2 O2-induced decrease in cell viability was evaluated by MTT assay.Hoechst 33342 staining and flow cytometry were applied to determine the role of miR-486-5p in the apoptosis of hMSCs.The protein expression was evaluated by Western blotting.Caspase-3 ac-tivity was determined using a caspase-3 activity kit.RESULTS:Compared with control group, the expression of miR-486-5p significantly decreased after treated with H2O2(P<0.05).In addition, over-expression of miR-486-5p in the hMSCs reduced the cell viability, accelerated apoptosis, down-regulated Bcl-2/Bax ratio, caspase-3 enzyme precursor content and phosphorylation of Akt, and activated caspase-3 activity.Conversely, down-regulation of miR-486-5p significantly inhibited H2 O2-induced cell apoptosis and the caspase-3 activity, increased cell viability and up-regulated Bcl-2/Bax ratio and phos-phorylation level of Akt.CONCLUSION:Over-expression of miR-486-5p promotes H2 O2-induced hMSCs apoptosis, and repression of miR-486-5p protects hMSCs from H2 O2-induced cellular apoptosis, which may be mediated by regulating Akt signaling pathway.

Objective To assess the reliability of auto-shimming line width (LW) and water suppression rate (WS), and the correlation between them. Methods GE Signa Excite HD 3.0T system and eight-channel torso phased-array coils with PRESS sequence were performed in 38 volunteers. Liver spectra were collected with TR of 1500 ms, TE of 30 ms, VOI of 2 cm×2 cm×2 cm, NSA of 64 times. Spectroscopy routine auto-shimming pre-scanning program was executed and the values of LW and WS were recorded. Then another spectroscopy routine auto-shimming pre-scanning program was performed repeatedly and 38 groups of data were obtained totally. Intra-class correlation coefficients (ICC), coefficient of variation (CV) and significance test were conduced on 38 groups of LW and WS data. Spearman rank correlation analysis was used to assess the correlation of LW and WS. Results ①The ICC of LW and WS was 0.862 and 0.961 (both P＜0.0001), respectively, while the value of CV was 0.20, 0.18, 0.09 and 0.08, respectively. Significant difference was not observed; ②The value of correlation coefficient was -0.659, -0.485 (both P＜0.0001), respectively. Conclusion ①The reliability is excellent for in vivo liver 3.0T 1H-MRS and WS appears relatively stable; ②Indexes of LW correlate with WS moderately, and it seems the smaller the value of LW is, the easier to achieve higher WS.

OBJECTIVES To analyse the diagnosis and treatment of 24 hereditary nonpolyposis colorectal cancer (HNPCC) kindreds and report mismatch repair gene mutations. METHODS The diagnosis, treatment and follow-up of 24 HNPCC kindreds were reviewed retrospectively, cancer incidence and spectrum were recorded. Clinical characteristics and treatment were analyzed. Peripherial blood and genomic DNA were extracted from family members who had provided informed consent. PCR and SSCP were used to screen coding regions of the hMLH1 and hMSH2 genes. Variant bands were sequenced by 377 DNA sequencer after purification. RESULTS One hundred and 25 malignant neoplasms were diagnosed in 75 patients (multiple cancers in 24) with an average age of 51 years in 24 pedigrees. The onset of the disease occurred earlier than expected with the passing of each generation within large kindreds. The neoplasm mainly included colonic cancer (63 patients), rectal cancer(21), stomach cancer(13), endometric cancer(7), and esophageal cancers(6). 84% patients received radical operations. Of 64 patients with colorectal cancer 16 had metachronous colorectal cancer. 24% colorectal patients developed metachronous cancer within 10 years after initial operation and received re-operation. In 3 detected families with germline hMSH2 and hMLH1 mutations resulting in truncated protein, 12 carriers were found. CONCLUSIONS The main characteristics of hereditary nonpolyposis colorectal cancer include early onset and frequence of cancer; predominance of colorectal cancer, especially right-sided colonic cancer; frequency of multiple primary cancer, especially colorectal cancer; and age anticipation in large HNPCC pedigrees. Segmental resection of colorectal cancer is not suitable for colorectal cancer patient in HNPCC kindred. Intensive follow-up is important for all patients and possible gene carriers.

OBJECTIVETo investigate the correlation between tissue factor (TF) expression and hepatic metastasis and prognosis in rectal cancer.

METHODSTF expression was retrospectively studied by immunohistochemical method in specimens of 40 rectal cancer, 3 hepatic metastasis and 6 benign adenoma with relation to their clinicopathologic data.

RESULTS1. TF expression was detected in 20 (50%) of the 40 primary rectal cancer specimens and all the 3 hepatic metastatic specimens, but not in the 6 benign adenoma or normal mucosa of rectum, 2. Significant correlation was observed between TF expression and synchronic hepatic metastasis (P = 0.002) and heterochronic hepatic metastasis (P = 0.001) and 3. TF was a risk factor for the prognosis of primary rectal cancer (P = 0.024).

CONCLUSIONTissue factor expression may play a role in the process of developing hepatic metastasis. It may be considered as a new clinical indicator for monitor of hepatic metastasis and prognosis of primary rectal cancer.
