Objective To observe the effect of eradication of helicobacter pylori (Hp) combined with comprehensive rehabilitation treat-ment on patients with non-alcoholic fatty liver disease (NAFLD). Methods From December, 2015 to April, 2016, 219 patients diagnosed as NAFLD with Hp infection were enrolled, in which 119 patients (observation group) were treated with anti Hp quadruple therapy. They were tested with 13C urea breath test one month after drug withdrawal. The other 100 patients were as control group. The severity of NAFLD was observed with abdominal ultrasound after six months. Results After treatment, Hp was eradicated in 107 cases (90.68%) in the observation group, one dropped out for pulmonary infection. After six months, the severity of NAFLD improved better in the patients eradicated Hp in the observation group than in the control group (χ2=8.397, P<0.05). Conclusion Eradication of Hp combined with comprehensive rehabilita-tion treatment can improve the severity of NAFLD.

Objective To prepare an antiserum of human putative magnesium transporter protein (HPT protein) to study its biological effects on the drug resistance of gastric cancer cell by observing its expression level. Methods The cDNA encoding HPT protein was cloned and sequenced. Prokaryotic expression vector was constructed and HPT protein fused with histidine tag was expressed. Mice were immunized with the polyacrylamide gel particles containing the fusion protein, and the antisera of them were detected for antibody activity by Western blot. Using the antiserum, HPT protein expression level was assessed in different gastric cancer cell line. Results The sequence of cloned cDNA fragment was consistent with that of HPT. After BL21/pRSETB bacterium was induced with IPTG, a new protein band with a relative molecular weight of 55kD was showed on SDS PAGE profile, and further proved to be fusion protein with histidine tag by Western blot. The antiserum of immunized mice only recognized a unique protein band with a relative molecular weight of 50kD. HPT protein expression level in SGC7901/ADR was higher than in SGC7901. Conclusion The antiserum of HPT protein was successfully prepared, and HPT was found to probably take part in the gastric cancer cell MDR

BACKGROUND:Percutaneous transforaminal endoscopic discectomy combined with radiofrequency annuloplasty is a minimaly invasive therapy for chronic discogenic low back pain, especialy suitable for lumbar disc herniation. OBJECTIVE:To evaluate the safety and short-term efficacy of percutaneous transforaminal endoscopic discectomy combined with radiofrequency annuloplasty for treatment of lumbar disc herniation. METHODS:Thirty-two patients with lumbar disc herniation were subjected to percutaneous transforaminal endoscopic discectomy combined with radiofrequency annuloplasty. Visual analogue scale and modified Macnab criteria were used to evaluate the relief of low back pain, and the Oswestry Disability Index was used for daily life evaluation of patients. Al the patients were folowed for 1-6 months, with an average of 3.5 months. RESULTS AND CONCLUSION:The operation was successfuly completed in al patients, and no complications such as damage to nerve and vascular systems occurred. Low back pain and living ability of the patients were improved obviously. Visual analog scale score and the Oswestry Disability Index were improved significantly after operation (P < 0.01); according to Macnnab's criteria, the results showed that at 1 week after the operation, the effective rate reached 94%; at 3 months after the operation, the effective rate was up to 97%. These findings indicate that percutaneous transforaminal endoscopic discectomy combined with radiofrequency annuloplasty in the treatment of lumbar disc herniation is confirmed in the short-term efficacy, and characterized as fewer complications and stable functional recovery.

The replicase genes of five isolates of Cucumber green mottle mosaic virus from Jiangsu, Zhejiang, Hunan and Beijing were amplificated, sequenced and analyzed. The similarities of nucleotide acid sequences indicated that 129 kD and 57 kD replicase genes of CGMMV-No. 1, CGMMV-No. 2, CGMMV-No. 3, CGMMV-No. 4 and CGMMV-No. 5 were 99.64% and 99.74%, respectively. The similarities of 129 kD and 57 kD replicase genes of CGMMV-No. 1, CGMMV-No. 3 and CGMMV-No. 4 were 99.95% and 99.94%, while they were lower between CGMMV-No. 2 and the rest of four reference sequences, just from 99.16% to 99.27% and from 99.04% to 99.18%. All reference sequences could be divided into six groups in neighbor-joining (NJ) phylogenetic trees based on the replicase gene sequences of 129 kD, 57 kD protein respectively. CGMMV-No. 1, CGMMV-No. 3 and CGMMV-No. 4 were clustered together with Shandong isolate (Accession No. KJ754195) in two NJ trees; CGMMV-No. 5 was clustered together with Liaoning isolate (Accession No. EF611826) in two NJ trees; CGMMV-No. 2 was clustered together with Korea watermelon isolate (Accession No. AF417242) in phylogenetic tree of 129 kD replicase gene of CGMMV; Interestingly, CGMMV-No. 2 was classified as a independent group in phylogenetic tree of 57 kD replicase gene of CGMMV. There were no significant hydrophobic and highly coiled coil regions on 129 kD and 57 kD proteins of tested CGMMV isolates. Except 129 kD protein of CGMMV-No. 4, the rest were unstable protein. The number of transmembrane helical segments (TMHs) of 129 kD protein of CGMMV-No. 1, CGMMV-No. 2, CGMMV-No. 3 and CGMMV-No. 5 were 6, 6, 2 and 4, respectively, which were 13, 13 and 5 on the 57 kD protein of CGMMV-No. 2, CGMMV-No. 4 and CGMMV-No. 5. The glycosylation site of 129 kD protein of tested CGMMV isolates were 2, 4, 4, 4 and 4, and that of 57 kD protein were 2, 5, 2, 5 and 2. There were difference between the disorders, globulins, phosphorylation sites and B cell antigen epitopes of 129 kD and 57 kD proteins of tested CGMMV isolates. The current results that there was no significant difference between the replicase gene sequences, it was stable and conservative for intra-species and clearly difference for inter-species. CGMMV-No. 1, CGMMV-No. 3, CGMMV-No. 4 and CGMMV-No. 5 had. a close genetic relationship with Shandong and Liangning isolates (Accession No. KJ754195 and EF611826), they are potentially originate from the same source. CGMMV-No. 2 was closer with Korea isolate. High sequence similarity of tested samples were gathered for a class in phylogenetic tree. It didn't show regularity of the bioinformatics analysis results of 129 kD and 57 kD proteins of tested CGMMV isolates. There was no corresponding relationship among the molecular phylogeny and the bioinformatics analysis of the tested CGMMV isolates.

Anaplastic lymphoma kinase (ALK) rearrangement is one of the most potent carcinogenic genes in non-small cell lung cancer (NSCLC).The first-generation ALK inhibitor such as crizotinib is superior to chemotherapy for NSCLC patients with ALK rearrangement.At the same time,more and more studies have reported ALK inhibitors in brain metastases of NSCLC patients with intracranial efficiency.However,despite the initial clinical data of first-generation ALK inhibitors in the treatment of ALK-positive NSCLC with brain metastases,different degrees of recurrence of tumors after acquired resistance have posed new challenges for follow-up treatment of cancer patients.A new generation of ALK inhibitors,such as alectinib;ceritinib,AP26113 and PF-06463922 have emerged to solve this problem.

Berbamine ( Ber. ) is a bis-benzyl-isoquinoline alkaloid isolated from the traditional Chinese medical herb, Berberis poiretis, and has Vide pharmacological effects. Clinical studies have demonstrated that Ber. had an effect of ingreasing the number of leukocytes in various leukocytopenia. But, up till now it has not been reported that Ber. take effect on enzymic metablism of inner cell and isoenzyme in the process of increasing leukocyte. The experiment observed the mice dynamic change of LDH in leukocyte and LDH isoenzyme of serum by cytochemistry and plane polyacrylamide gel electrophoresis tech-nigue. The result indicates that LDH enzyme reaction of granulocyte have increased in Ber. group and intensity of enzyme reaction has a positive interralation with the time of administrations. All specimen show 5 zones after LDH isoenzyme pattern analyse. The proportion of LDH-5 was changed and LDH-5 sub-band was detected in control and combination group. The experiment indicated that Ber. can affeet enzymic metablism of inner cell in the process of increasing leukocyte. There was simultaneously with a change in ratio of LDH isoenzyme pattern.

Objective To assess the clinical efficiency of percutaneous coronary intervention (PCI) on cor-onary artery disease patients with complicated lesions (CAD-CL). Methods A total of 252 patients of CAD-CL treated with PCI from August,2002 to September,2009 were enrolled in the study. Clinical data on prognosis e. g, success rate, complication occurrence and major adverse cardiac events were observed. Results Two hundred and forty-four patients with CAD-CL(including chronic obstruction, bifurcation lesion, long lesion and restenosis) were implanted stent successfully(96.83%), with no residual stenosis or residual stenosis less than 20%. There were col-lateral obstructions in 32 patients and artery secret compartment in 48 patients, and restenosis in 15 patients. One patient of acute anterior myocardial infarction complicated by cardingenic shock was in low blood pressure status after two anterior descending artery stent placement, and died after temporary pacemaker implantation and other positive rescue measures. One patient occurred subacute stent thrombosis on the third day, and was cured after occlusive vas-cular recanalization through emergency PCI. Conclusions Percutaneous coronary intervention for coronary artery disease patients with comphcated lesion is safe and effective.

Objective To investigate the clinical and epidemiological characteristics of pulmonary thromboembolism (PTE) and deep venous thrombosis (DVT). Methods The clinical data of 114 200 inpatients from June 2002 to June 2008, including gender, age, smoking history, primary disease and risk factors, were reviewed. Results There were 1445(1.27%) cases with venous thromboembolism (VTE), while 1433(1. 25%) patients suffered from DVT and 153(0. 13%) patients suffered from PTE, 16(11. 11 %) patients were dead of PTE. Of all the DVT patients, there were 1348(94. 1%) cases with DVT of lower limbs with no significant difference between left or right lower limb (P>0. 05). There were 49(3.4%) cases with inferior vena cava, 23(1.6%) cases with cavitas pelvis veins and 13(0. 9%) cases with upper extremity veins. The peak ages of morbidity were between 51 to 60 years. Conclusions The incidence of VTE is increasing with ageing and there is no significant difference between males and females. The most common risk factors for thromboembolism include trauma, surgery, cardiac and pulmonary disease, age over 50 years, deep phlebitis, long-term smoking, cancer, pregnancy, childbirth, braking, history of VTE, etc. We may lower the incidence and mortality of VTE by strengthening prevention work according to the high risk factors.
