Objective To study the effect of oral chemotherapy on patients of pancreatic carcinoma undergoing Whipple′s procedure. Methods48 cases undergoing radical pancreaticoduodenectomy with regional lymphadenectomy were divided into two groups. 24 cases received oral chemotherapy consisted of 5′ DFUR and calcium folinate for a course of 6 months. ResultsThe clinicopathological features were similar between the two groups. During the period of follow up,5 cases in chemotherapy group died including motality caused by liver metastasis in 2 cases whereas 7 cases died of liver metastasis in the control group( P

ObjectiveTo evaluate the diagnosis and treatment of primary non-Hodgkin′s lymphoma (PNHL) of the pancreas. MethodThe therapeutic result of 6 cases admitted from January 1980 to March 2000 was reviewed retrospectively. ResultsThe lesion was located in the head of the pancreas in 2 cases and the body and/or tail in 4, respectively. Clinical manifestations included epigastric discomfort, loss of weight, abdominal mass and jaundice. Two cases underwent Whipple′s procedure and distal pancreatectomy respectively, the other 4 underwent laparotomy and biopsy. B cell non-Hodgkin′s lymphoma of 5 cases and T cell non-Hodgkin′s lymphoma of one were verified by pathology. One patient lost follow-up, the other 5 patients survived 58, 49, 22, 13 and 4 months respectively. Conclusion The clinical manifestation and radiological features of PNHL of the pancreas are not specific. Comprehensive therapy including surgery is beneficial to the long-term survival of patients with PNHL of the pancreas.

Objective To analyze the incidence and risk factors of microalbuminuria in newly diagnosed and hospitalized type 2 diabetes mellitus patients,and to provide the theoretical basis for therapy of diabetes and diabetic chronic complications.Methods The blood glucose,lipid profile,24h-urinaryalbumin,fasting and postprandial serum insulin and peptid C were measured in 286 newly diagnosed and hospitalized type 2 diabetic patients from Mar.2006 to Sep.2009.Microalbuminuria was defined as the 24h-urinary albumin between 30 to 300 mg twice.Insulin resistance index (HOMA-IR) was recorded and all the patients received fundus examination by ophthalmologists after expansion of the pupil to ensure whether there was retinopathy or not.Results (1)The incidence rate of microalbuminuria in this study was 19.58％ (56/286).(2)Normal albuminuria group and MA group combined DR were 19.57％ (45/230) and 33.93 ％ ( 19/56 ) respectively,and the difference was statistically significant( x2 =5.349,P =0.021 ).Compared with control,the FPG,HbA1c and HOMA-IR were significantly higher in microalbuminuria group ( FPG:[ 11.08 ± 1.76 ] mmol/L vs [9.24 ±1.65]mmol/L,t =-6.148,P ＜0.001;HbA1c:[11.54 ± 1.59]％ vs [9.39 ± 1.64]％,t =-7.533,P ＜0.001 ;HOMA-IR:[3.73 ±0.42] vs [3.50 ±0.30],t =-3.774,P ＜0.001 ).(3) Pearson correlation analysis revealed microalbuminuria was positively correlated with FPG( r =0.460),HbA1 c ( r =0.499),HOMA-IR( r =0.308)and combined DR(r =0.405)(P ＜0.01).(4)Stepwise multiple regression analysis revealed that FPG (ββ =- 0.804,P ＜ 0.01 ),HbA1 c (β =- 0.455,P ＜ 0.01 ) and combined DR (β =1.527,P ＜ 0.05 ) were independently risk factors of microalbuminuria.Conclusion The development of microalbuminuria in newly diagnosed and hospitalized type 2 diabetic patients is associated with FPG,HbA1c and HOMA-IR,and will be easier to merge diabetic retinopathy.

Objective To investigate clinicopathological features、diagnosis and surgical treatment of duodenal stromal tumors. Methods A retrospective clinical analysis was made in 23 cases of duodenal stromal tumors admitted from 1995 to 2004. Results Melena and abdominal pain was the most common presenting symptom. Complete resection was achieved in all cases, including pancreatoduodenectomy in 13 cases, by pylorus-preserving pancreatoduodenectomy in 3 cases, and tumor enucleation in 7 cases. The mean size of the tumor was 6. 6 cm (2 - 21 cm) , among them 10 cm in 6. Pathologically tumors less than 5 cm were all of potential malignancy, whereas those larger than 5 cm were malignant. Follow-up of 2 months to 9 years found all cases alive and healthy except for one who died of liver metastasis one year postoperatively. Conclusion Duodenal stromal tumors were low malignancy tumors. Aggressive surgery is the choice of treatment. Favorable prognosis is expected after complete surgical excision.

AIM:To investigate the effects of osteogenic induction media and the medias containing different concentration of calcium on the induction of osteogenic differentiation of human renal fibroblasts in vitro.METHODS: Culturedhuman renal fibroblasts were divided into 5 groups in this experiment: osteogenic induction group (osteogenic inductionmedia), CaⅠgroup (0.5 mmol/L Ca2 + media), CaⅡgroup (1.5 mmol/L Ca2 + media), Ca Ⅲ group (2.5 mmol/LCa2 + media) and control group (PBS).The cell activity in each groups was measured by MTT assay .At 9th day, the cellcalcium Alizarin red S staining and alkaline phosphatase (ALP) Gomori calcium cobalt staining were performed respectivelyto observe the formation of calcium nidus and the expression of ALP .In addition, the expression of Runt-related transcriptionfactor 2 (Runx2) at mRNA and protein levels was determined by real -time PCR and Western blot, respectively.RE- SULTS: The remarkable positive signs which represented the formation of calcium nidus and the deposit of calcium objectsin all experiment groups were observed .The mRNA and protein expression of Runx2 in osteogenic induction group increasedin accordance with the induction time .Compared with control group, the mRNA and protein expression of Runx2 inthe CaⅠ ~Ⅲ groups increased gradually in a calcium concentration dependent manner at the 9th induction day.CON- CLUSION: Human renal interstitial fibroblasts show the potential activity in osteogenic differentiation induced by osteogen -ic induction media or high level calcium in vitro, which may be account for the cytological formation of the Randall ’splaque in the kidney.

Hepatotoxicity is one of the most common adverse reactions during anti -hyperlipidemia treatment .Mechanisms of anti-hyperlipidemia drug-induced hepatotoxicity are not clear yet , but most of the toxic reactions are dose-related hypersensitivity and could be released after drug withdrawal .It is accepted that clinical risk factors for the development of hepatotoxicity during anti -hyper-lipidemia treatment are high age and chronic illnesses .Treatment of anti-hyperlipidemia drug-induced hepatotoxicity has not been uni-fied and most of the treatments are non-specific and symptomatic .Researching hypotoxicity and hepatoprotection antihyperlipidemia drug, especially TCM and pharmaceutics will become a promising direction .

Acute gastrointestinal dysfunction is a common and important complication of sepsis. As no exiting formal definition and classification of gastrointestinal dysfunction, most of the treatment strategies for gastrointestinal dysfunction are not based on clinical evidence, but on their own clinical experience. Experts of traditional Chinese medicine, integrated traditional Chinese and Western medicine and Western medicine from various disciplines in Shanghai are organized by the Shanghai Society of Integrated Traditional Chinese and Western Medicine and the Emergency Department Branch of Shanghai Physicians Association. After repeated discussion, literature search and formulation of the outline, we developed consensus on gastrointestinal dysfunction secondary to sepsis with integrating Traditional Chinese Medicine and Western medicine by consulting extensively on clinical experts in the fields of emergency medicine, gastroenterology, general surgery, infectious medicine and traditional Chinese medicine, and holding several expert forums and consultation meetings. This clinical expert consensus focused on acute gastrointestinal injury (AGI) classification and inducer of sepsis. In this consensus, the common symptoms, diagnosis, classifications, treatment strategies and suggestions of acute gastrointestinal injury or dysfunction secondary to sepsis were explored from the aspect of both Traditional Chinese Medicine and Western medicine.

OBJECTIVE:To provide reference for promoting the rational use of Dexamethasone sodium phosphate injection in the clinic. METHODS:Special comment criteria and evaluation rules was formulated,medical records of 1273 inpatients receiving Dexamethasone sodium phosphate injection were collected from our hospital during Jul. 2014-Jun. 2015. Rationality of drug use was evaluated and analyzed retrospectively. RESULTS:The most use amount and case number of Dexamethasone sodium phosphate injection were in the departments of blood/oncology,obstetrics,emergency minimally invasive surgery,gastrointestinal surgery,emergency trauma of orthopedics and thyroid breast surgery;while much less were in departments of new pediatrics, infection and rehabilitation. There were 138 cases of irrational use of Dexamethasone sodium phosphate injection found in special comment, and the total irrational use rate was 10.84％ . The types of irrational use included inappropriate indication (contraindication,59.42％),inappropriate drug combination(18.84％),inappropriate drug selection (15.94％),inappropriate usage and dosage(3.62％)and inappropriate drug dosage forms or drug delivery methods(2.17％),etc. The irrational use rate of Dexamethasone sodium phosphate injection monthly declined steadily by month from 30.35％ in Jul. 2014 to 7.81％ in Jun. 2015 through the special comment;then a consensus of 5 points for the drug use formed in our hospital. CONCLUSIONS:There are irrational situations in the clinical use of Dexamethasone sodium phosphate injection in our hospital,especially in the cases of inappropriate indications. The rationality of the drug can be improved by the development of the special comment. This work should continue to be carried out in the future and perfected.

Objective:To investigate the clinical efficacy of 125I seed implantation combined with anlotinib hydrochloride in the treatment of non-small cell lung cancer (NSCLC). Methods:61 cases of NSCLC patients were enrolled, of which 30 cases (observation group) received 125I seed implantation combined with anlotinib treatment, and 31 cases (control group) received 125I seed implantation only. To evaluate the curative effect and adverse reactions of all patients, the carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA21-1), neuroendocrine enolase (NSE), squamous cell carcinoma antigen (SCC) in the peripheral blood of the two groups was measured before the treatment and at 1 and 3 months after the treatment. Results:The effective rates in the observation group were 90.00% and 93.33%, the effective rates in the control group were 67.74% and 74.19% at 1 and 3 months after the treatment, respectively, and the difference in efficacy between the two groups was statistically significant ( χ2=4.504, P=0.034 vs. χ2=4.075, P=0.044). There was no significant difference in the incidence of adverse reactions between the two groups of patients after treatment ( P=0.785). At 1 and 3 months after the treatment, the levels of CEA, CYFRA21-1, NSE and SCC in the peripheral blood of the two groups of patients were lower than those before the treatment (all P<0.05). Conclusions:125I seed implantation combined with anlotinib hydrochloride is safe for the treatment of advanced non-small cell lung cancer, and has promotion value.

Objective To construct the Hut78 cell line with EZH2 gene knocked into by CRISPR/Cas9 system. Methods The EZH2 expression vector pMD-18T-EZH2 with homologous arm and the sgRNA expression vector pSpCas9 (BB)-2A-Puro-sgRNA, which could cut the double stranded genomic DNA, were constructed, and the two vectors were co-transfected into Hut78 cells. Then the expression of EZH2 mRNA was detected by qPCR, and the expressions of EZH2 and H3K27me3 proteins were detected by Western blot assay. Results The pMD-18T-EZH2 and pSpCas9(BB)-2A-Puro-sgRNA recombinant vectors were confirmed by DNA sequencing. When Hut78 cells were transfected with the two recombinant plasmid, qPCR results showed that the expression of EZH2 mRNA was significantly increased, and Western blot analysis showed that the expressions of EZH2 and H3K27me3 proteins were significantly increased. Conclusion EZH2 gene is successfully knocked into Hut78 cells by CRISPR/Cas9 system.
