AlM:To study and investigate the change situation of trace elements and body comprehensive immune state of patients with viral keratitis.METHODS:Sixty-two patients with viral keratitis in our hospital from December 2011 to February 2014 were selected as observation group, 62 healthy persons with health education at the same time were the control group, then the serum and tear Zn, Cu, cellular immunity and erythrocyte immunity of two groups were compared, and the detection results of observation group with different types and severity degree were compared.RESULTS:The serum and tear Zn of observation group was all lower than that in control group, serum and tear Cu was higher than that in control group, cellular immunity and erythrocyte immunity indexes were all worse than that in control group, the detection results of observation group with mild, moderate and severe infection had significant differences (P<0. 05), while the detection results of observation group with herpes simplex keratitis and herpes zoster keratitis had no significant differences (P>0. 05).CONCLUSlON: The change of trace elements and body comprehensive immune state of patients with viral keratitis are obvious, and the severity degree for the detection levels of keratitis are greater.

Objective:To investigate the expression of wild type estrogen receptor(wER)and the ex-on-5 deleted ER(variant ER,vER)in human hepatocellular carcinoma(HCC)samples,and thereafteranalyze the possibility of HCC treatment by endocrine therapy.Methods:The mRNA expressions of wERand vER were analysed from 28 cases of HCC by RT-PCR.The expression of ER at the protein level wasdetected by immunohistochemistry(IHC).Results:IHC results showed that 39.3% of the HCC speci-mens expressed ER.The mRNA of wER was detected in 89.3%(25/28)of the HCC specimens whilethat of vER was detected in 96.4%(27/28).Twenty four out of 28 HCC cases(85.7%)expressedboth wER and vER.One out of 28 patients(3.5%)expressed only wER whereas 3 patients out of 28(10.7%)expressed vER only.Conclusion:Ninety six percent(27/28)of the HCC patients expressedvER,which suggests that the expression of vER is an important event in the development of HCC.

ObjectiveTo explore the feasibility, safety and clinical value of laparoscopic Rouxen-Y cystojejunostomy in the treatment of pancreatic pseudocyst. Method Four patients with pancreatic pseudocyst received totally laparoscopic pancreatic pseudocystojejunostomy. The data on intraoperative bleeding, operative time, postoperative time to get out of bed, time of first flatus/bowel motion, complication and duration of hospital stay were collected and analyzed retrospectively. ResultsAll operations were carried out successfully with laparoscopic surgery. The mean operative time was 90 min. The average intraoperative blood loss was 40 ml. The mean postoperative time to get out of bed was 1.5 d, and the mean time of first flatus/bowel motion was 2. 3 d. All patients recovered smoothly without any pancreatic fistula. The average hospital stay was 7 days. Fever, pancreatitis,adhesive intestinal obstruction and other complications did not occur. ConclusionsTotally laparoscopic Roux-en-Y pancreatic pseudocystojejunostomy was an efficacious, safe, and minimally invasive procedure.

Objective Myofascial pain syndrome (MPS) is a common muscle function disturbance.This study was to investigate the clinical value of acoustic radiation force impulse (ARFI) imaging in assessing the therapeutic effect of acupuncture for patients with trapezius MPS.Methods A total of 116 patients diagnosed with trapezius MPS received acupuncture therapy once a day for 10 days in Pudong Hospital from August 2015 to June 2016.Using ARFI imaging, we recorded the shear wave velocity (SWV) of the trapezius and obtained the short-form McGill Pain Questionnaire (SF-MPQ) scores of the patients before, at the end of, and at 7, 15 and 30 days after treatment.Then, we analyzed the interaction and correlation between the SWV values and SF-MPQ scores of the patients at different time points.Results Both the SF-MPQ scores and SWV values were first decreased, falling to lowest values (5.19 points and 1.43 m/s) at 7 days after treatment, and then increased again.The interaction between the SF-MPQ scores and SWV values were significantly different at different time points (Finteraction=2.553, Pinteraction=0.038), and there was a strong linear correlation between the two indexes (r=0.755, P=0.000).Conclusion ARFI imaging combined with SF-MPQ has a certain clinical value in assessing the effect of acupuncture on trapezius MPS.

Objective To explore the feasibility of mechanical chest compression to establish a rat model of car?diopulmonary resuscitation ( CPR) . Methods 4?month old healthy male Sprague Dawley rats were randomly divided into control group ( n=6 ) and model group ( n=10 ) . After induction of anaesthesia with 10% chloraldurate ( 3 ml/kg, i. p. ) , tracheal intubation and left femoral artery cannulation were performed. Under electrocardiographic and artery blood pressure monitoring, tracheal obstruction ( TO) was performed to rats in model group. At 2 min after the cardiac arrest ( CA) occurred, CPRs were administered to the rats using a self?made animal chest compressor, which provided chest?com?pression at a rate of 200 bpm. Results Shortly after TO, rats in the model group had respiratory arrest, cyanosis and ar?rhythmia. Electrocardiography indicated that CA occurred within 4-5 min, with a decreased artery systolic blood pressure ( <40 mmHg) and a zero pulse pressure. Return of spontaneous circulation ( ROSC) after the CPR was successfully a?chieved in 8 rats (80%), with a transient reperfusion arrhythmia. Finally, 60% of the rats (n=6) recovered to con?sciousness and survived for 24 hrs. The serum biochemical analysis indicated that there were electrolyte disturbances, aci?dosis, impaired renal functions and increased myocardial enzyme spectrum. Pathological examination revealed cardiac rhab? domyolysis, no?reflow phenomenon in renal glomeruli, decrease of neurons and pulmonary congestion in the model group rats. Conclusions Mechanical chest compression can provide minimal cardiac output for the requirement of CPR incardiac arrestin rats. It is feasible to establish rat CPR model with the mechanical chest compression.

Objective To study the effect of interventional treatment of iliac and femoral vein stenosis concomitant with deep venous thrombosis. Method Fifty-three patients were divided into 5 groups. In group A after placing into inferior vena cava a filter,11 patients adopted Amplatz Trombectomy Device for thrombolysis or ORSIS thrombolysis and persistent thrombolysis through popliteal vein. In group B thrombus was taken out through guiding catheter and then persistent thrombolysis through popliteal vein after placing into inferior vena cava filters in 9 cases. In group C 13 patients adopted persistent thrombolysis through femoral arteries. In group D 8 patients received persistent thrombolysis through popliteal vein. In group E persistent thrombolysis through foot veins was carried out in 12 patients. Seventeen patients received implanted stents and balloon-expansion in iliac and femoral veins. Results Symptoms disappeared in 26 patients(49.0%), significantly improved in 21 patients (39.6%), improved in 3 patients (5.7%), did not improve in 3 patients (5.7%), respectively. The repatency of iliac and femoral vein was achieved in more than 80% of the 17 patients. Complications developed in 3 cases in the course of thrombolysis. Conclusion The effect of mechanical removal of thrombus, persistent thrombolysis through catheter and transluminal angioplasty is safe and satisfactory.

Objective To investigate the antiproliferative effect of rosiglitazone, a thiazolidinedione (TZD) on autosomal dominant polycystic kidney disease (ADPKD) cystic lining epithelial cells and to explore the underlying molecular mechanism. Methods ADPKD cysticlining immortalized epithelial (WT9-12) cells were stimulated by rosiglitazone with different concentrations. After treatment, MTT method was performed to detect the level of proliferation; flow cytometry was used to determine the cell cycle distribution and the apoptosis rate. Western blotting was used to detect the protein expressions of mTOR, p70S6K, 4E-Bp1, PPARγ PPARγ siRNA was transfected into WT9-12 cells to knock down the expression of PPARγ Results Treatment of WT9-12 cells with rosiglitazone resulted in a dose-dependent and time-dependent strong inhibition of cell proliferation, an accumulation of cells in the G0/G1 phase (rosiglitazone 50 μmol/L 65.43%,rosiglitazone 100 μmol/L 64.02%, control 49.65% ) and 6% apoptosis at high concentration (rosiglitazone 200 μmol/L). Rosiglitazone reduced the phosphorylation of p70S6K in a dosedependent and time-dependent manner. The levels of phosphorylated mTOR and 4E-Bp1, the latter being a downstream substrate of mTOR related mRNA translation initiation, were not changed by rosiglitazone. Cells were pre-incubated with GW9662, a PPARγ antagonist, before the treatment with rosiglitazone, the inhibition of p70S6 kinase phosphorylation by rosiglitazone was partially prevented by GW9662 (P＜0.01). Then PPARγ siRNA was transfected into WT9-12 cells, in contrast to untransfected control or cells transfected with an irrelevant siRNA, rosiglitazone did not cause an obvious inhibition of p70S6 kinase phosphorylation in PPARγ knock-down.Conclusion Rosiglitazone inhibits the proliferation of ADPKD cystic lining epithelial cells, and down-regulates p70S6 kinase phosphorylation through mTOR-independent and PPARγ-dependent signal pathway.

Objective To explore the increment of molluscicidal effect and reduction of the cost as well as increasing snail control area by complex commercial molluscicides. Methods Nicotinanilide and niclosamide were combined with the proportion of 1∶1 (The complex of short term was complex molluscicide), and then the snail control tests by immersion and spraying methods were performed using the complex molluscicide in laboratory and field. Meanwhile, the snails climbing from water as they contacted with molluscicide was observed. Results Under the temperature 23-25℃ in lab and 8-19℃ in the field, 0.4 mg/L of the complex by immersion for 48 h, the mortalities of the snails were 100% and 97% respectively. Using 0.4 g/m 2 of complex by spraying for 48 h in lab and the field, the mortalities of the snails were 100% and 81.1% respectively. The rate of snails climbing from water in the complex group decreased by 72.1% compared with the nicotinanilide group. The difference between the two groups was obviously significant (P

Arginine Deiminase(ADI) was purified to homogeneity using ammonium sulfate precipitation,Q-Sepharose Fast Flow anion exchange chromatography and SephadexG-75 gel filtration chromatography. This purification protocol resulted in a 34.5-fold purification of ADI with 31.4% final yield. A molecular weight of about 190 kD determined by native gradient polyacrylamide gel electrophoresis. The enzyme has only one kind of 46 kD subunit determined by SDS-PAGE. Combining the results from the two kinds of electrophoresis,the authors deduce that the enzyme may be a tetramer. The optimum pH and temperature for lipolytic activity of ADI was pH 6.5 and 50℃,respectively. It was extremely stable at 45℃ and retained 97.9% of its original activity for 30 min. The stability declined rapidly as soon as the temperature rose over 50℃. ADI was highly stable in the pH range from pH 5-8. ADI acted on L-arginine but not on D-arginine. ADI catabolism was dependent on metal ions. At their adequate concentration,Mn2+,Mg2+ and Co2+ were the effective promoter,while superfluous Zn2+and Co2+ inhibited ADI activity. L-citrulline did not act on ADI,but L-ornithine inhibited ADI activity. The degradation of L-arginine with ADI catalysis was according to simple Michaelis-Menten equation. The Michaelis constant was 3.2686 mmol/L and the maxi-mum velocity was 2.44 ?mol/min.

Objective To analyze the clinical characteristics, risk factors, prevention, and treatments of de novo malignant tumors after orthotopic liver transplantation (OLT). Methods The clinical data of 4 patients with de novo malignant tumors out of the 726 patients undergoing OLT from October 2003 to December 2008 were analyzed. Results The morbidity of de novo malignant tumors after OLT was 0.6 % (4/726), and all of them were men. The 4 de novo malignant tumors were respectively diagnosed as acute myeloid leukaemia, gastric carcinoma, lung cancer, undifferentiated embryonal sarcoma of the liver. The age of patients during OLT was 42-57 years (mean 52 years). The age of patients' onset was 45-60 years (mean 53 years). The length was 6-38 months from liver transplantation to diagnosis of de novo malignant tumors (mean 31 months). All of the 4 patients died of tumor progression and multiple organ failure. The survival time was 12-48 months after OLT (mean 39.5 months), and that was 6-10 months after diagnosis of de novo malignant tumors (mean 8.5 months). Conclusion The incidence of de novo malignant tumors after OLT in China is lower than in abroad. The delayed diagnosis time is a main cause of death for patients with de novo malignant tumors after OLT. To think highly of precancerous lesions and high risk of factors, early diagnosis, and early treatment are the keys to improve the survival time.
