Objective To evaluate the relationship between 5,10-Methylenetetrahydrofolate reductase(MTHFR) gene polymorphisms and colorectal cancer(CRC).Methods Studies were selected based on the criteria for inclusion.The Meta-analysis software,REVMAN 4.2,was applied for checking the heterogeneity across the studies and calculating the pooled OR.The results were evaluated by the analyses of publication bias and sensitivity.Results A total of 9 787 cases and 12 986 controls from 18 studies for C677T and a total of 4 422 cases and 5 819 controls from 9 studies for A1 298C were included.No heterogeneity among the studies was found.For codon 677,the frequencies of CC,CT and TT genotypes were 46.48%,43.81% and 9.71% in cases,and 45.03%,43.08% and 11.89% in controls,respectively.The pooled OR of TT vs.CT+CC was 0.80(95%CI 0.74～0.87).For codon 1 298,the frequencies of AA,AC and CC genotypes were 53.60%,39.39% and 7.01% in cases,and 53.31%,38.67% and 8.03% in controls,respectively.The pooled OR of CC vs.AC+AA was 0.84(95%CI 0.72～0.97).Conclusions MTHFR 677TT is at lower risk of developing CRC and 1 298CC genotypes might be associated with the decreased risk of developing CRC.

Objective To explore the risk factors of diabetic nephropathy.Methods According to the excretion rate of proteinuria,90 patients were divided into 3 groups:normal diabetic proteinuria group (DM),diabetic micro-proteinuria group (DN1),and clinical diabetic proteinuria group (DN2).We compared patients'ages,diabetic course,cholesterol,triglyceride,glycosylated hemoglobin,high density lipoprotein cholesterol (HDL),low density lipoprotein cholesterol (LDL),serum p-selectin,serum C-reactive protein,urinary monocyte chemotactic protein,and proteinuria excretion rate.Logistic regression analysis was used to analyze the relation between DN and various factors.Results Differences among these groups were statistically significant in type 2 diabetic course,HDL,LDL,p-selectin,C-reactive protein,glycosylated hemoglobin,and urinary monocyte chemotactic protein (P ＜ 0.05).Logistic regression analysis showed that diabetic course,LDL,C-reactive protein,p-selectin,and urinary monocyte chemotactic protein were independent risk factor (OR values were 2.238,1.062,6.723,1.166,and 1.046).Conclusions Occurrence and severity of DN had relationship with course of diabetes,microvascular lesions,and inflammatory reaction.Emphasis on monitoring and evaluation of the DN-related factors would contribute to the prevention and treatment of DN.

Objective To investigate the effects of multiple doses of propofol or/and monosialotetrahexosyl ganglioside (GM1) on cognitive function and caspase-3 expression in immature rats.Methods Seventy-seven immature SD rats,17-18-day old and weighted 33-40g,were randomly divided into 7 groups (11 each):control group (NS),propofol 50mg/kg group (P50),propofol 100mg/kg group (P_ 100 ),propofol 200mg/kg group (P_ 200 ),GM1 10mg/kg group (G),propofol 100mg/kg and GM1 10mg/kg group (P_ 100 G),and propofol 200mg/kg and GM1 10mg/kg group (P_ 200 G).Each group received normal saline,propofol 50mg/(kg?d),100 mg/(kg?d),200mg/(kg?d),GM1 10mg/(kg?d),propofol 100mg/(kg?d) and GM1 10mg/(kg?d),or propofol 200 mg/(kg?d) and GM1 10mg/(kg?d) intraperitoneally in a bolus or divided doses,respectively,for 6 consecutive days.The tests of learning and memory were performed in Morris water maze everyday at the 3rd hour after the rats waked up from anesthesia.The animals were sacrificed on the 6th day after the Morris water maze test to obtain the brain specimen,and the expression of caspase-3 was detected by immunohistochemistry and Western blotting.Results Latency period of water maze test was significantly longer in groups P_ 100,P_ 200 and P_ 200 G than in group NS,and the frequency of crossing platform were fewer in P_ 100,P_ 200 and P_ 200 G groups (P

OBJECTIVE To investigate the resistance of clinical isolated strains to the commonly used antibacterials in our hospital 2007-2008.METHODS Clinical isolated strains and sensitivity of drugs were detected by ATB system.The result of drug sensitivity was judged by CLSI standard and analyzed with statistical software WHONET5.3.RESULTS Altogether 3150 strains bacteria were isolated,17.4% were Gram-positive strains and 82.6% were Gram-negative strains,and the top five isolates were Pseudomonas aeruginosa,Escherichia coli,Klebsiella pneumoniae,Acinetobacter baumannii,and Staphylococcus aureus.The reasistance rate of Gram-positive strains to minocycline was 15.4%.Five VRE strains were isolated.Various Enterobacteriaceae bacteria were sensitive to imipenem meropenem,cefoperazone-sulbactam and piperacillin-tazobactam,and their rate was 86.5% to 97.7%.Some of Acinetobacter and Stenotrophomonas maltophilia were multidrug resistant.CONCLUSIONS It is serous that multidrug resistance of isolated strains of the patients exists in our hospital.

Objective To assess the risk factors that could influence the severity of esophageal inju- ry in patients with gastroesophageal reflux disease(GERD).Methods GERD patients diagnosed on the ba- sis of endoscopic reflux esophagitis or pathological results of 24 hour esophageal pH monitoring were divided into three groups as non-erosive reflux disease group(NERD)(n=83),mild esophagitis group(n=51) and severe esophagitis group(n=22).The clinic data and esophageal pH parameters were recorded in the three groups.A logistic regression was used to assess the joint influences of clinic characteristics,hiatus her- nia,and esophageal pH parameters on the severity of esophageal injury.Results Patients in severe esoph- agitis group were more likely to have advanced age and hiatus hernia.The number of supine long reflux epi- sodes measured by esophageal pH monitoring significantly increased with increasing grades of mueosal dam- age(P

Objective To explore the treatment experience and surgical strategy in papillary thyroid carcinoma (PTC) patients with parapharyngeal lymph node metastasis. Methods A retrospective review was performed on ten patients with PTC metastasis to parapharyngeal lymph node from January 2005 to August 2014. The treatment experience and surgical strategy were analyzed. Results Three patients accepted initial treatment and 7 patients had a history of surgical treatment prior to PTC. Parapharyngeal lymph node metastasis was diagnosed by imaging examination or fine needle aspiration cytology. Resection of lymph node metastasis was performed via transcervical approach and transmandibular approach. Total thyroidectomy and neck dissection were performed synchronously. All patients received 131I therapy after surgery and did not have recurrence in neck or parapharyngeal space. During follow-up, 3 patients died in 5 years because of lung metastasis, 3 patients survived with tumor , and 4 patients survived without recurrence. The 5-year overall survival rate was 7/10 and the 5-year disease-free was 4/10. Conclusions Parapharyngeal lymph node metastasis from PTC may occur in patients with previous neck dissection or widespread cervical metastases. CT and MRI is helpful for establishing the diagnosis. Surgical resection remains the mainstay of treatment for this disease. PTC patients with parapharyngeal lymph node metastasis have a poor prognosis.

Objective To investigate the effect of small interfering RNA (siRNA) mediated silencing of △Np73 on 5-FU chemotherapy sensitivity in SW620 colocancer cells and provide new treatment approach for the colon cancer.Methods siRNAs were transfected into SW620 colon cancer cells.The expression of △Np73 was observed.Cell viability of colon cancer cells were measured by MTr assay and cell apoptosis was assessed with flow cytometry after treatment of control siRNA or △Np73 siRNA or combined with 5-FU,respectively.The tumorigenesis was assessed by injecting △Np73 siRNA or control siRNA transfeeted SW620 colon cancer cells into nude mice,followed by treatment with 5-FU in the tumors.Results △Np73 siRNA was able to strongly inhibit △Np73 expression,however,it did not inhibit the growth of cells.Combination treatment with △Np73 siRNA and 5-FU produced significant higher apoptotic cell(42.9%) as compared with those with 5-FU treatment(18.9%) alone or those with △Np73 siRNA(8.8%) alone.The treatment with 5-FU in the xenngrafts derived from △Np73 siRNA transfected SW620 cells in nude mice can inhibitor tumor growth significantly (t=15.32,P<0.05).Conclusion △Np73siRNAs can specifically repress the expression of △Np73.Thus it sensitizess the cells to 5-FU chemotherapy in colon cancer.

Objective To probe into the operative techniques and clinical outcomes of treating bi-columnar acetabular fractures. Methods From April 2001 to December 2006, 609 cases undergoing operation for aeetabular fractures were followed up. Of them, 193 eases, 147 males and 46 females with an average age of 34.4 years, were of bi-columnar type. Their complications involved the articular cartilage of the femoral head in 37, eranioeerebral trauma in 31, injury to bladder and/or urethra in 27, injury to thorax and/or abdomen in 68, injury to pelvis and/or sacroiliac joint in 59, and injury to sciatic nerve in 11. The interval between injury and surgery was within 1 week in 15 cases, within 2 weeks in 121, within 3 weeks in 34, and beyond 3 weeks in 23. A single ilioinguinal approach was adopted for 4 cases and combined ap-proaches for 189. Results The mean operating time was 238 (150 to 330) minutes, and the blood loss averaged 1453 (450 to 4400) mL. The mean follow-up period was 44.2 (14 to 84) months. All the eases were evaluated by Matta reduction criteria, X-ray manifestations and the modified Merle d'Aubingne and Postel clinical scoring. One hundred and sixty-eight patients got anatomical reduction, 17 unsatisfactory reduction, and 8 poor reduction. The X-ray manifestations were excellent in 162 patients, good in 16, fair in 8, and poor in 7. The clinic results were excellent in 152 patients, good in 27, fair in 9, and poor in 5. The Kendall coefficient correlation between reduction and clinical outcome and that between reduction and X-ray manifes-tation were 0.74 and 0.77, respectively. Ectopic ossification happened in 77 eases and transient post-operative sciatic nerve paralysis occurred in 3. Conclusions The combined approaches facilitate exposure and synergetie reduction of the bi-colunmar fractures of acetabulum. Reduction of the acetabular roof is essential to restoration of the normal contour of the acetabulum. Reduction bears a positive correlation to the clinical results as well as experience of surgeons.

The effects of ultrafine grinding on the dissolution rates of the effective components in Sanjie Zhentong capsule (SZC) were studied in this experiment. Fine and ultrafine powder of SZC intermediates were made by ordinary grinding and ultrafine grinding technology, and then granulated by wet granulation. SZC were prepared by fine powder, ultrafine powder and ultrafine granules, respectively. With resveratrol and loureirin B as investigated indexes, dissolution rates of the four intermediates in SZC were determined by cup method and HPLC.
