Objective To study the effect of early enteral nutrition(EN) and total parenteral nutrition(TPN) in patients with severe acute pancreatitis by a mata analysis.Methods Randomized controlled trials of TPN and early EN in patients with severe acute pancreatitis were searched in Medline,Pubmed and Embase from Jan 1970 to June 2009,and Cochrane Library(Issue 2,2009).Seven studies were enrolled into the analysis.The detail about the trial design,characters of the subjects and results of the studies were reviewed by two independent authors and analysed by using Revman 5.0.18 software.Results Compared with TPN,early EN was associated with a significantly lower incidence of pancreatic infections(OR =0.38,95% CI :0.18～0.82,P =0.01),organ failure(OR =0.43,95% CI :0.23～0.79,P =0.007),fewer surgical interventions(OR =0.34,95% CI :0.18～0.63,P =0.0006) and mortaily(OR =0.41,95% CI :0.19～0.88,P =0.02).However,there was no significant difference in total infections [ OR =0.43,95% CI(0.17,1.10),P =0.08]between patients with TPN and early EN.Conclusions Early EN could be the preferred nutrition feeding method for patients with severe acute pancreatitis.

Objective 　To investigate the factors associated with long-term efficacy of microvascular decompression for hemifacial spasm. Methods　253 cases of hemifacial spasm treated with microvascular decompression were followed 13 to 144 months (mean 73 months). Results　Hemifacial spasms were obliterated in 232 cases (91.7%) and were partially relieved in 10 cases (4%). However, hemifacial spasm recurred 11 cases (4.3%). We re-operated on those who had recurrent hemifacial spasm and found that the material used for previous decompression had moved. The movement of decompression material could be the cause of spasm recurrence. Conclusions　Upholding of depression material around the blood vessels against movement near the facial nerve plays an important role for improving the long-term efficacy of MVD for hemifacial spasm.

Objective To investigate the therapeutic effects and mechanism of biliopancreatic diversion (BPD) surgery on type 2 diabetes mellitus(T2DM) in GK rats.Methods 16 GK rats were randomly divided into 2 groups:BPD surgery group included 10 rats undergoing BPD surgery,sham-BPD group included 6 rats undergoing a sham operation.Fasting plasma glucose,insulin,glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide(GIP)were detected one week before BPD surgery and the 1st week,4th week,10th week,26th week after BPD surgery.Oral glucose tolerance test(OGTT) and insulin tolerance test(ITT) were done in the 10th week after BPD surgery.Results There was no statistical difference in fasting plasma glucose,insulin,plasma GLP-1 or GIP between the 2 groups before surgery.Plasma glucose had significant reduction in BPD group compared to that in the sham group(P ＜0.05) and insulin level had no significant difference between the 2 groups.Rats in BPD group had significant improvement in glucose tolerance and insulin sensitivity compared to those in the sham group.Serum level of GLP-1 was significantly elevated in BPD group compared to that before surgery (P =0.0337 at the 1st week after surgery; P =0.0002 at the 4th week after surgery,P ＜ 0.0001 at the 10th week after surgery,P ＜0.0001 at the 26th week after surgery) and that in sham-BPD group(P =0.0354 at the 1st week after surgery,P =0.0032 at the 4th week after surgery,P =0.0001 at the 10th week after surgery,P ＜0.0001 at the 26th week).Serum level of GIP was significantly lowered in BPD group compared to that before surgery(P =0.0189 at the 1st week after surgery; P =0.0007 at the 4th week after surgery,P =0.0003 at the 10th week after surgery,P ＜0.0001 at the 26th week after surgery) and that in sham-BPD group(P =0.0089 at the 1st week after surgery,P =0.0002 at the 4th week after surgery,P =0.0006 at the 10th week after surgery,P ＜0.0001 at the 26th week after surgery).The difference had statistical significance (P ＜0.05).Conclusion BPD surgery can significantly reduce fasting plasma glucose,improve glucose tolerance and insulin sensitivity.The change of serum levels of GLP-1 and GIP may play the major role in BPD treatment of diabetes mellitus.

Objective To detect the expression of BP1 gene in thyroid cancer and its relationship with clinicopathological features of thyroid cancer.Methods BP1 gene expression in 60 cases of thyroid cancer tissues and 20 cases of normal thyroid tissues were detected by in situ hybridization and immunohistochemistry.Results The positive expression rate of BP1 mRNA was 78.3 ％ (47/60) in the 60 cases of thyroid cancer tissues while it was 20％ (4/20) in the 20 cases of normal thyroid tissues detected by in situ hybridization.The difference had statistical significance (P ＜ 0.05).Of the 3 pathological types of thyroid cancer,the positive expression rate of papillary carcinoma was 81.6％ (40/49),follicular carcinoma 85.7％ (6/7),and medullary carcinoma 25.0％ (1/4).The expression of BP1 mRNA had statistical difference between medullary carcinoma and other pathological types like papillary carcinoma and follicular carcinoma (P ＜ 0.05).The positive expression rate of BP1 protein was 93.3％ (56/60)in the 60 cases of thyroid cancer tissues while it was 10.0％ (2/20) in the 20 cases of normal thyroid tissues detected by immunohistochemistry.The difference had statistical significance(P ＜0.05).Conclusion BP1 gene expression is up-regulated in human thyroid cancer and it is related to tumor stage and pathological type but not related to patients' age,sex or lymph node metastasis.

Objective To study the therapeutic effects and prognosis of advanced pancreatic carcinoma treated with iodine-125 seeds implantation.Methods The records of 98 patients with unresectable advanced pancreatic carcinoma admitted from Mar.2004 to Oct.2008 were analyzed.There were 53 cases treated by supportive treatment,24 cases by palliative operation and 21cases by palliative operation combined with iodine-125 seed implantation.Results Pain partial and complete relief rate in palliative operation combined with iodine-125 seeds implantation radiotherapy group(84.21% and 15.79%,respectively) was better than other two treatment groups(P

Objective The risk of current pancreaticojejunostomy is carefully considered from the perspective of the morphology of remnant pancreas,and we aimed to discuss the clinical outcomes of selecting different pancreaticojejunostomy techniques based on pancreatic morphology.Methods This was a prospective cohort study.The histopathology of remnant pancreatic tissues was categorized into four types based on preoperative radiological images and intraoperative palpation:Type Ⅰ:pancreas with hard texture in palpation,pancreatic atrophy,dilated pancreatic duct larger than 5 mm and remnant pancreatic surface ＜3 cm;Type Ⅱ:pancreas with hard texture in palpation,pancreatic atrophy and mild dilatation of pancreatic duct with the diameter of 3-5 mm and remnant pancreatic surface ＜3 cm;Type Ⅲ:pancreas with slightly hard texture,no atrophy,and normal or slightly dilated pancreatic duct with the diameter of 3-5 mm and remnant pancreatic surface ≥3 cm;Type Ⅳ:pancreas with soft texture,normal morphology and pancreatic duct.Results From January 2008 to August 2017,116 consecutive patients underwent pancreaticoduodenectomy in our center.Among them,10 patients with type Ⅰ underwent classic pancreatic ductal mucosa to mucosa anastomosis.19 patients with type Ⅱ underwent classic end to end invaginated pancreaticojejunostomy.45 patients with type Ⅲ underwent classic end to end invaginated pancreaticojejunostomy with overlapping U sutures;42 patients with type Ⅵ underwent total invaginated pancreaticojejunostomy.The post-operative pancreatic fistula occurred in 6 patients (5.2％) with one patient died.Postoperative bleeding occurred in 10 patients (8.6％),and gastroparesis occurred in 22 patients (19.0％).Overall complication rate was 33.6％.Conclusions Classification of pancreatic morphology based on preoperative radiological images and intraoperative palpation and the selection of corresponding pancreaticojejunostomy technique is theoretically rational and has the advantage of potentially reducing the risk of remnant pancreatic tissue.

Objective To understand the situations of departments of intensive care units (ICUs) of different level hospitals in Guizhou Province, and to provide directions and evidences for improving quality control in critical care medicine.Methods A county-level hospital and a provincial-level hospital's comprehensive ICU in Guizhou Province were selected to record and analyze and compare the structural indicators, patient admission and transfer, disease distribution, ventilator associated pneumonia (VAP), intravascular catheter related blood stream infection (CRBSI) and catheter-associated urinary tract infection (CAUTI) of the two hospitals' comprehensive ICU in 2017.Results The ICU of the People's Hospital of Suiyang County (county hospital) was found in 2012, and the ICU of the Affiliated Hospital of Guizhou Medical University (provincial hospital) was found in 1994. Until 2017, there were 10 and 46 beds, 6 (all of them hold bachelor's degree) and 18 physicians (6 of them hold PhD, 5 of them hold master's degree, 7 of them hold bachelor's degree), 17 (4 of them hold bachelor's degree, 13 of them hold college degree or graduated from secondary school) and 69 nurses (2 of them hold master's degree, 53 of them hold bachelor's degree, 14 of them hold college degree or graduated from secondary school) in the two ICUs respectively, there were significant differences in the education background of the physicians and nurses between the two ICUs (bothP < 0.01). During 2017, 471 cases were admitted to the ICU of the county hospital while 1633 cases were admitted to the ICU of the provincial hospital. Compared with the ICU of the provincial hospital, the ratio of the patients with acute physiology and chronic health evaluationⅡ(APACHE Ⅱ) ≥ 15 at admission was lower (74.8％ vs. 85.1％,P < 0.01), the ratio of direct admission was higher (30.8％ vs. 17.4％,P < 0.01), the ratio of the patients admitted to the ICU more than once was lower (0.8％ vs. 5.0％,P < 0.01), the ratio of the patients whose the length of ICU stay less than 24 hours was higher (51.6％ vs. 13.7％,P < 0.01), the ratio of the patients whose the length of ICU stay more than 28 days was lower (1.1％ vs. 2.9％, P < 0.05), the ratio of the patients discharged against-advice (25.5％ vs. 20.5％,P < 0.05) was higher, the ratio of the patients transferred to other hospitals was higher (5.1％ vs. 0.3％,P < 0.05), and the ICU mortality was lower (4.0％ vs. 13.9％,P < 0.01) in the ICU of the county hospital. The top three kinds of diseases treated in the ICU of the county hospital were brain injury (27.4％), trauma (19.1％) and toxication (6.8％); while in the ICU of the provincial hospital were brain injury (18.6％), sepsis (16.2％) and severe acute pancreatitis (4.8％). In addition, the incidences of VAP, CRBSI and CAUTI in the ICU of the county hospital were 10.0/1000 ventilator days, 1.4/1000 catheter days, 0.5/1000 catheter days; while in the ICU of the provincial hospital were 5.8/1000 ventilator days, 2.0/1000 catheter days, 3.7/1000 catheter days, respectively.Conclusions There are short of physicians and nurses in the ICU of the provincial and county hospitals in Guizhou Province, and the educational level of the medical staff in the ICU of the county hospital is relatively low. Moreover, there were significant differences in the admissions and treatments and the outcomes of the critically ill patients between the two ICUs. The characteristics of the ICUs of county hospitals should be fully considered when the quality control of critical care medicine and continuing medical education are done.
