The current treatment of chronic pancreatitis(CP) includes medicine, endoscopy, extracorporeal shock wave lithotripsy (ESWL) and surgical methods. In this paper, a variety of treatments of chronic pancreatitis, mainly progress in surgical methods are reviewed.

Fluid therapy plays a quite important role in peri-operation period,however,conventional measurements are not sensitive to hypovolemia.Goal directed fluid therapy( GDT),which is based on balance of oxygen delivery and consumption,can achieve the aim of fluid therapy more efficiently.Many RCTs have proven that GDT could reduce morbidity,shorten hospital time of high risk surgical patients,therefore,it is a beneficial work.

Pustular psoriasis is not a rare inflammatory skin disease, and is characterized by sudden onset of generalized erythema and sterile pustules complicated by chills, high fever, neutrophilia and elevated levels of C?reactive protein. Due to frequent recurrence, it greatly impacts the quality of life in patients. Recently, it has been gradually found that IL36RN, CARD14 and AP1S3 mutations are associated with the occurrence of pustular psoriasis, and accordingly some new therapeutic approaches have emerged. This review summarizes recent advances in genetics of pustular psoriasis.

Objective To analyze mutations of the STAT3 gene in a patient with hyper-IgE svudrome (HIES) mainly manifesting as multiple cold abscesses.Methods Clinical data were collected and blood samples were obtained from a 17-year-old male patient with HIES and his parents.Genomic DNA was extracted and subjected to PCR for the amplification of the entire coding region and splice sites of the STAT3 gene followed by bidirectional sequencing.Results A heterozygous missense mutation C1427T,which caused a codon change from TCC to TTC and resulted in the substitution of serine by phenylalanine at amino acid residue 476 (p.S476F), was found in exon 16 encoding the DNA-binding domain in the STAT3 gene in the patient, but not in either of his parents.The results of amplified ribosomal DNA restriction analysis were consistent with the findings mentioned above.Conclusion A novel missense mutation S426F was found in the STAT3 gene in the HIES patient with generalized cold abscesses as the prominent clinical manifestation.

Objective To investigate effects of angiotensin Ⅱ receptor antagonist Losartan on the expression of TGF ? 1mRNA in rats with cirrhosis and the mechanism.Method Forty one male SD rats were divided into normal control ( n =10), cirrhotic control ( n =11), and Losartan treated cirrhotics ( n =20) with Losartan (10?mg?kg -1 ?d -1 ) treatment started on the first day along with CCl 4 administration and on the 5th week, respectively.Expression of TGF ? 1 mRNA was examined with reverse transcriptase polymerase chain reaction (RT PCR).The expression of TGF ? 1 protein was assayed with immunochemistry.Result Expression of TGF ? 1 mRNA and TGF ? 1 protein were up regulated in rats with cirrhosis (from 0 93?0 05 to 1 94?0 13, compared with the normal rats P

Objective To investigate the effect of L osartan, an angiotensin Ⅱ type receptor antagonist, on vascular endothelial gro wt h factor (VEGF) expression. Method Ｚ Liver cirrhosis was in duced by oral intake of 50% CCl4 at a dosage of 3?ml?kg-1?d- 1ⅹ 9 weeks in SD rats. In Losartan group,rats were given Losartan orally. Exp r ession of VEGFmRNA was examined with reverse transcriptase polymerase chain reac tion (RT-PCR) and the expression of VEprotein was assayed by immunohistochem istry. Result VEGF was highly e xpressed in cirrhotic group compared with control group (0.77?0.10 vs 1.94? 0.20, P=0.001) . In losartan treatment group, VEGF mRNA expression decreas ed to 1.02?0.1 and 0.86?0.15（P=0.001）. Concl usion Expression of VEGF increased in cirrhosis, Losartan inhibited this eff ect.

Objective To investigate the feasibility of reverse transcription_polymerase chain reaction (RT_PCR) to evaluate the inactivation efficacy of viruses in water, and to discuss the mechanisms of HAV inactivation by chlorine. Methods Cell cultrue, ELISA method and long_overlapping RT_PCR were developed to detect the infectivity, antigenicity and entire genome of HAV inactivated by chlorine. Results The cell culture results revealed that the infectivity was completely inactivated after exposure to 10 mg/L or 20 mg/L of cholrine for more than 30 minutes, the antigenicity was completely inactivated after exposure to 10 mg/L of chlorine for 60 minutes. The 5' nontranslated region (5'NTR) of neculear acids of HAV was the most sensitive to chlorine, which was confirmed with the inactivation of infectivity of HAV. Conclusions The results implied that the inactivation of HAV by chlorine was due to the loss the 5' NTR. It was believed that PCR could be used to assess the efficacy of disinfection of HAV by chlorine and also could be applied to research the inactivation mechanisms of viruses by disinfectants.

About 5％- 15％ patients suffered from gallbladder stones may have secondary bile duct stones.How to diagnose secondary bile duct stones in time preoperatively or intraoperatively has been a focus of research.In this paper,the advantages and disadvantages of a variety of diagnostic methods of secondary bile duct stones including B ultrasonography,computed tomography,percutaneous transhepatic cholangiography,endoscopic retrograde cholangiopancreatography,endoscopic ultrasonography,magnetic resonanced cholangiopancreatography,intraoperative cholangiography,intraoperative ultrasonography,choledochoscope,are reviewed.

Objective To investigate the distribution of pathogenic bacteria of vaginal discharge in bacterial vaginosis.Methods The results of bacterial culture and drug sensitive tests of vaginal discharge from patients with bacterial vaginosis were analyzed.Results The positive rate of bacteria culture of vaginal discharge was 79.3%(115/145).The dominant bacteria were staphylococcus epidermidis 27.0%(31/115),staphylococcus intermedius and staphylococcus aureus 13.0%(15/115),which were obviously higher than other germs.The drug sensitive tests showed that staphylococcus were relatively sensitive to vancomycin,fosfomycin,amikacin and rifampin.But the drug resistance to penicillin,tetracycline,erythromycin and oxacillin was the highest.Conclusion The kinds of pathogenic bacteria in vaginal discharge are various.The main bacterium is staphylococcus,and drug resistance is very severe.The isolation and drug sensitive test of pathogenic bacteria play an important role in diagnosis and treatment of gynecological disease.
