Objective To summarize the complication of clinical characteristics, factors causing misdiagnosis, and diagnosis of large intestine tuberculosis (LIT). Methods The data of twenty cases of LIT misdiagnosed preoperatively in our hospital were analyzed retrospectively. The difficulties of LIT diagnosis and management were studied and analyzed. Results Abdominal pain, mass, and the alteration of stool habit were the most common symptoms. LIT was most commonly confused with malignant tumor, Crohn's disease, and periappendicular abscess. Ten of 17 patients, who were performed exploratory laparotomy, were misdiagnosed as tumor or Crohn's disease. Most of our cases were not definitively diagnosed until the histopathologic examination after surgery. Three cases were diagnosed by other methods. Gastrointestinal X ray series, colonoscopy, endoscopic fine needle aspiration cytology(FNAC) and laparoscopic exploration may improve the diagnosis. Exploratory laparotomy with biopsy was the final procedure for diagnosis. Final diagnosis mainly depends on histology. Conclusions LIT lacks special clinical manifestations and has a high misdiagnosis rate. But if correct diagnosis is established, most patients can be cured and unnecessary exploratory laparotomy can be avoided. Six months antituberculosis treatment is effective for LIT whether the lesion is excised or not.

Objective To sum up the experience in the diagnosis and treatment of pancreatic duct stone developed as a result of long-term chronic pancreatitis. Methods The clinical data of 11 patients with pancreatolithiasis treated in our hospital from 1996 to 2002 were retrospectively analyzed. Results The main clinical manifestations included abdominal pain, back pain as well as exocrine and endocrine functional disturbance. The disease can be diagnosed by B-mode ultrasonography, CT and ERCP. Nine of 11 cases were treated by pancreaticojejunostomy, 1 case suffering from concurrent carcinoma of the head of the pancreas received pancreaticodudenectomy and 1 case underwent distal pancreatetomy. Ten patients who were followed up were free of pain . Conclusions B-mode ultrasonography is the best choice for the diagnosis of panceatolithiasis, and pancreaticojejunostomy should always be attempted for cases with duct dilatation .

Objective:To evaluate the prediction value of preoperative Fibrinogen(FIB) in combination with neutrophil-lymphocyte ratio(NLR)for the prognosis of operable pancreatic cancer patients.Methods:The clinical data of 124 patients who underwent radical resection for pancreatic cancer in our hospital from Jan 2010 to Dec 2018 were retrospectively analyzed.The patients were divided into three groups according the high and low NLR, FIB value which defined by the receiver operating characteristic curve (ROC). The clinicopathological data and overall median survival time were compared between the three groups.Results:Univarate analysis showed that age, tumor stage, NLR, FIB and F-NLR score were associated with the prognosis( P<0.05), while multivariate analysis showed that high F-NLR score was the independent prognostic factor. The median survival time of patients with F-NLR scores 0, 1 and 2 group was 30.6, 20.3 and 13.9 months( P<0.05). The prognosis of high F-NLR score was significantly worse than that of low F-NLR score( P<0.05). Conclusions:A high preoperative F-NLR score was a promising predictor for the prognosis of pancreatic cancer patients after radical resection.

Objective To evaluate surgical management of pancreatic duct stones.Methods From 1997 to 2007, 24 cases of pancreatic duct stones underwent surgical treatment, the clinical data were retrospectively analyzed. Results In this study, 17 cases underwent lithotomy by longitudinal pancreatic duct incision, Roux-en-Y anastomosis(side-to-side) of pancreatic duct to jejunum, extra drainageof the main pancreatic duct was done in two cases, hepaticojejunostomy in three cases, pancreaticcystojejunostomy in one case. One case suffered from postoperative bleeding at pancreatic ojejunostomy, one from stress ulcer, and both were cured by conservative treatment. Three cases underwent pancreaticeduodenectomy, anastomosis bleeding occurred in one patient, and was cured by conservative method. One case underwent duodenum-preserving resection of the head of the pancreas, 2 cases underwent distal pancreatectomy, one case underwent lithotomy by pancreatic duct incision and primary closure, no postoperative complications occurred among those patients. 21 cases were followed up, results were excellentin 17 patients. Conclusions Lithotomy by longitudinal pancreatic duct incision, Roux-en-Y anastomosisof pancreatic duct to jejunum is the main and effective surgical procedure, while duodenum preserving pancreatic head resection and lithotomy by pancreatic duct incision and primary closure are also rational for the treatment of pancreatic duct stones.

Thymopentin (TP5) and bursopentin (BP5) are both immunopotentiators. To explore whether the TP5-BP5 fusion peptide (TBP5) has adjuvant activity or not, we cloned the TBP5 gene and confirmed that the TBP5 gene in a recombinant prokaryotic expression plasmid was successfully expressed in Escherichia coli BL21. TBP5 significantly promoted the proliferation of thymic and splenic lymphocytes of mice. The potential adjuvant activity of the TBP5 was examined in mice by coinjecting TBP5 and H9N2 avian influenza virus (AIV) inactivated vaccine. HI antibody titers, HA antibodies and cytokines levels (IL-4 and IFN-γ) were determined. We found that TBP5 markedly elevated serum HI titers and HA antibody levels, induced the secretion of both IL-4 and IFN-γ cytokines. Furthermore, virus challenge experiments confirmed that TBP5 contributed to inhibition replication of the virus [H9N2 AIV (A/chicken/Jiangsu/NJ07/05)] from mouse lungs. Altogether, these findings suggest that TBP5 may be an effective adjuvant for avian vaccine and that this study provides a reference for further research on new vaccine adjuvants.

Objective: To observe the effects of manganese( Ⅲ ) meso-tetrakis (N, N'-diethylimidazolium-2-yl) porphyrin (MnTDM) in treatment of early Parkinson's disease(PD) mouse model induced by subcutaneous injection of 1-methyl-4-phenyl1, 2, 3, 6-tetrahydropyridine(MPTP) and to discuss its possible mechanism. Methods:Forty male C57BL/6 mice were evenly randomized into 4 groups: MPTP model group(subcutaneous injection of 25 mg/kg MPTP for 3 days), MnTDM+ MPTP group (15 mg/kg MnTDM was subcutaneously injected 1 h before MPTP injection), MnTDM control group, and normal saline group. Performance of animals in the pole and swimming test was observed 3 days after the last injection. Levels of dopamine (DA) and its metabolites(3,4-dihydroxyphenylacetic acid [DOPAC] and homovanillic acid [HVA]) in the striatum of animals were measured by high-performance liquid chromatography with an electrochemical detector(HPLC-ECD). Thiobarbituric acid (TBA) method was used to examine the levels of malondialdehyde(MDA). Results: Acute injection of MPTP could be used for establishment of PD model. The striatal levels of DA, DOPAC and HVA in MPTP group were significantly lower(P<0.01)and the striatal level of MDA was significantly higher(P<0.05) than those of the control group. MPTP had no obvious effect on the behavioral performance of the animals in a short term. MnTDM could partly inhibit the above effects of MPTP. Compared with MPTP group, MnTDM+ MPTP group had significantly higher DA, DOPAC, and HVA levels and significantly lower MDA level(all P<0.05). There was no significant difference in the behavioral indices of animals between the 4 groups. Conclusion:MnTDM can inhibit lipid peroxidation and promote DA production; it has preventive and therapeutic effects on MPTP induced PD.
