Objective To study the effects of small dosage insulin on intestinal inflammatory responses to endotoxin rats. Method Thirty two male SD rats were randomly divided into 4 groups (n = 8): control group, endotoxin (LPS,6 mg/kg i.p.)group, regular insulin(RI,0.5 IU/kg hypodermic) group and LPS(6 mg/kg i.p) + RI (0.5 IU/kg hypodermic)group. Six hours after LPS or saline injection,all rats were laparotomized to observe the congestion in intestinal mucosa with naked-eyes and photography.Then a segment of intestine was stained with HE to observe the pathological changes. The expressions of IL-6 and TNF-α were detected by RT-PCR.The systemic inflammatory response,blood sugar and food taken in rats were observed simultaneously. Software SPSS 13.0 was used to perform ANOVA and Chi-square test for statistical analysis. Results Compared with LPS group, the differences in hyperemia and inflammatory cell infiltration in intestinal tissue were not noticeable in LPS + RI group. The expression of IL-6 and TNF-α were significantly attenuated in RI + LPS group (P < 0.01). All rats in LPS group manifested systemic inflammatory response syndrome (SIRS) four or five hours after LPS treatment, while there was none in LPS + RI group. Rats in LPS group took less food than rats of other groups while the blood sugar had litter difference in all groups (P > 0.05). Conclusions Small dosage of insulin could reduce intestinal inflammation caused by endotoxemia. Early administration of insulin ould prevent the presence of SIRS while it has no obvious influence on blood sugar.

BACKGROUND: Neurological complications after coronary artery bypass grafting still have a high incidence rate, and the etiology is multiple.OBJECTIVE: To retrospectively investigate the occurrence and relevant factors of severe neurological complications after coronary artery bypass grafting (CABG).METHODS: A total of 761 consecutive patients with undergoing CABG were included in this study from September 2002 to August 2009 at the Nanjing Drumtower Hospital, including 443 males and 318 females, aged from 32-89 years. All patients were grouped according to age(more than or less than 70-year-old) and on pump or off pump coronary surgery. Disclose the relationship between the risk factors and the neurological complications by statistics analysis.RESULTS AND CONCLUSION: Totally 41 patients had serious neurological complications in this study. There was a higher complication incidence in 570-year-old group patients (n=22) than < 70-year-old group (n=19)(14.9% vs. 3.1%, P< 0.001). The neurological complications incidence was similar in on-Pump CABG group (n =7) and off-Pump CABG group (n = 34) (5.3% vs.5.4%, P=0.39). The incidence rate of severe neurological complications was high in carotid artery stenosis > 50% patients. A total of 8 cases died, 2 for massive hemorrhage of gastrointestinal tract; 1 for severe sepsis; 4 for multiple organ dysfunction syndrome;1 for epilepsia gravior postoperatively. Finally, 33 cases survived. The average time of follow up was 3 years, 3 cases died, 3 cases recovery from limitation of limb or hand movement partly, and 1 case had severe mental retardation. Results displayed that elderly patients(= 70 years) undergoing CABG are at higher risk of neurological dysfunction. Carotid artery stenosis is the most risk factor. There are no significant effects on postoperative complications between on-pump CABG and off-pump CABG.

Objective:To study the relationship between telomerase activity and the expression of proliferating cell nuclear antigen(PCNA) in oral squamous cell carcinoma (OSCC). Methods:Telomerase activity and expression of PCNA in 68 cases of OSCC,34 cases of epithelium immediately adjacent to carcinomas and 12 cases of normal oral mucosa were detected by TRAP-PCR-ELISA and immunohistochemical SP method. Results:The positive rate of telomerase in OSCC, the epithelium immediately adjacent to carcinomas and the normal oral mucosa was 67.65%(46/68), 8.82%(3/34) and 0(0/12) respectively. Telomerase activity in OSCC was related to the grade of the clinicopathology(P

BACKGROUND: Renin-angiotensin-aldosterone system existed in bone tissue. Recent studies on antihypertensive drugs found that angiotensin converting enzyme inhibitor type antihypertensive drug was possibly effective for osteoporosis. Perindopril is one of the commonly used antihypertensive drugs. Whether perindopril affected bone metabolism or could be used in anti-osteoporosis has not been reported.
OBJECTIVE: To observe effects of perindopril on bone metabolism in a rat model of osteoporosis induced by retinoic acid.
METHODS: Fifty Sprague-Dawley rats were randomly divided into five groups, with ten in each group. In the model group and each perindopril groups, rats were intragastricaly administered retinoic acid solution 80 mg/kg per day. After successful model establishment, rats in different perindopril groups were intragastrical y administered perindopril 2, 4 and 8 mg/kg per day, once a day, for 42 consecutive days. In the normal control and model groups, rats were given an equal volume of distil ed water. Serum calcium, phosphorus, alkaline phosphatase, bone mass and bone mineral density were detected in each group. Expression of bone specific alkaline phosphatase and tartrate-resistant acid phosphatase mRNA in bone tissue was determined.
RESULTS AND CONCLUSION: Compared with the model group, after treatment with perindopril, serum calcium and phosphorus levels were increased, alkaline phosphatase activities were significantly decreased, bone mass and bone mineral density were obviously increased in rats with retinoic acid-induced osteoporosis. Expression of bone specific alkaline phosphatase mRNA was higher in the perindopril 8 mg/kg group than in the perindopril 2 and 4 mg/kg groups and model group. Tartrate-resistant acid phosphatase mRNA expression was higher in the perindopril 8 mg/kg group than in the model group. These results indicated that perindopril could improve partial bone metabolic biochemical markers in osteoporosis rats, promoted bone formation by up-regulating bone specific alkaline phosphatase mRNA expression, and had a certain preventive effect on retinoic acid-induced osteoporosis.

Objective To investigate the related factors of early liver cancer recurrence associated with elevated fasting glucose levels after radical resection of liver cancer.Methods The retrospective cohort study was adopted.The clinical data of 145 patients with liver cancer who were admitted to the Nanfang Hospital of Southern Medical University from October 2009 to June 2013 werc collected.After radical resection of liver cancer, 111 patients with average level of fasting blood glucose (FBG) ＜ 6.1 mmol/L and 34 patients with level of FBG ≥ 6.1 mmol/L were divided into the normal group and the hyperglycemic group, respectively.The blood glucose levels of patients during the period of hospital stay and follow-up were observed.The status of early recurrence and risk factors affecting recurrence in the 2 groups were analyzed.Follow-up of outpatient examination was applied to patients up to July 1, 2015 with the first recurrence as the end point.Patients had reexaminations once every month within postoperative month 6 and once every 3 months after 6 months.The general information [gender, age, FBG, underlying hepatopathy, preoperative AFP, alanine transaminase (ALT), aspartate aminotransferase (AST), Child-Pugh stage, Barcelona Clinic Liver Cancer (BCLC) stage, history of alcohol drinking], surgical data (surgical method, operation time, number of blood transfusion, volume of intraoperative blood loss), pathological data (histopathological differentiation, number of tumor nodules, diameter of maximal tumor, liver cirrhosis) and follow-up data (postoperative AFP, imaging findings, recurrence time, preventive chemotherapy) were collected.Measurement data with normal distribution were presented as-x ± s and analyzed by the t test.Measurement data with skewed distribution were presented as M (range) and analyzed by the non-parametric test.Count data were analyzed using the chi-square test.With the first recurrence as the end point, the tumor-free survival rate was drawn using the Kaplan-Meier method, and the comparison was analyzed by the logrank test.The risk factors affecting recurrence were analyzed using the Kaplan-Meier method for proportional hazards assumption test firstly, and then eligible factors were done using Log-rank test in the univariate analysis.The multivariate analysis was done using the COX model.Results The postoperative 1-, 2-year overall recurrence rates of liver cancer were 28.3％ (41/145) and 45.5％ (66/145).And 1-, 2-year recurrence rates of liver cancer were 21.6％ (24/111) and 36.9％ (41/111) in the normal group and 50.0％ (17/34) and 73.5％ (25/34) in the hyperglycemic group, respectively, showing significant differences between the 2 groups (x2=10.335, 14.053, P ＜ 0.05).The univariate analysis showed that FBG, Child-Pugh stage, volume of intraoperative blood transfusion and postoperative AFP were risk factors affecting tumor-free survival rate after radical resection of liver cancer (x2 =17.591,6.492, 10.690,12.820, P ＜ 0.05).The tumor-free survival rates at postoperative month 24 in the normal group and hyperglycemic group were 63.1％ and 26.5％ respectively, showing significant difference between the 2 groups (x2=17.591, P ＜ 0.05).The results of multivariate analysis showed that level of FBG ≥6.1 mmol/L, volume of intraoperative blood transfusion ＞ 200 mL and postoperative level of AFP ＞ 8.1 pg/L were independent risk factors affecting tumor-free survival rate after radical resection of liver cancer (RR =2.542, 2.028, 2.724, 95 ％ condifence interval : 1.529-4.225,1.183-3.479,1.635-4.538, P ＜ 0.05).Conclusions Elevated FBG level has a stimulative effect on early recurrence of tumor after radical resection of liver cancer.As a result, monitoring and controlling of blood glucose after operation is helpful in decreasing the early recurrence rate of patients with liver cancer.

Objective The prosthesis used for aortic valve replacement (AVR) can be too small in relation to body size,thus causing valve prosthesis-patient mismatch (PPM).The aim of this article was to summarize the preventive strategy of PPM during AVR.Methods A total of 357 patients [203 males,154 females; mean age (54.9 ± 18.7 ) years ] underwent AVR between February.2010 and December 2011.The weight and body surface area (BSA) of the group is( 60.1 ± 11.4 )kg and (1.67 ± 0.21 )m2 respectively.The aortic valve prosthesis effective orifice area (EOA) was divided by body surface area (BSA) to obtain the EOA index (EOAI).PPM was then defined as none or mild if EOAI was ＞ 0.85 cm2/m2,as moderate for (0.65 - 0.85 ) cm2/m2 and as severe for ＜ 0.65 cm2/m2.To avoid PPM,a simple three-step algorithm was applied:Step 1,Calculate the patient's BSA from weight and height;Step 2,Calculate the minimal valve EOA required based on the BSA to ensure an EOAI ＞0.85 cm2/m2 ; Step 3,Select the type and size of prosthesis that has reference values for EOA greater or equal to the minimal EOA value obtained in step 2.For patients with a small aortic root,the following three methods was used:( 1 ) Replace aortic valve with simple interrupted suture technique ; (2) Apply new type and high-performance prosthetic valves such as St.Jude Medical Regent mechanical valve ; (3) Enlarge the narrowed aortic root when necessary.Results Of all 357 patients,272 patients received mechanical AVR and 85 bioprosthetic AVR.Among the 49 patients who received AVR with simple interrupted suture technique.St.Jude Medical Regent mechanical valve was implanted in 38 patients and the aortic root enlargement was performed in 11 patients.The total prevalence of PPM was 6.4％ and there was no severe PPM.The prevalence of PPM with mechanical AVR and bioprosthetic AVR was 1.8％ and 21.2％ respectively.There were 4 deaths during early period of operation,and the operative mortality was 1.1％.Conclusion Prosthesis-patient mismatch can be effectively prevented at the time of AVR with appropriate measurement.

Objective To investigate the surgical efficacy for the treatment of ruptured anterior communicating artery aneurysms with different dome projections in acute phase via supraorbital lateral approach.Methods From January 2014 to March 2017,the clinical data of 79 patients with acute ruptured anterior communicating artery aneurysm with different dome projections in acute phase treated via supraorbital lateral approach in the First Affiliated Hospital of Soochow University were retrospectively analyzed.The operative efficacy was analyzed.The Glasgow outcome scale (GOS) score was used to evaluate the prognosis at 3-36 months after procedure.Results In the 79 patients,34 were superior dome projections,37 was inferior dome projections,and 8 were complicated dome projections.All the anterior communicating artery aneurysms were successfully clipped.The patients were followed up for 3-36 months after procedure.GOS showed good prognosis in 70 cases (88.6％),of which 26 were superior dome projections,36 were inferior dome projections,and 8 were complicated dome projections;9 suffered mild disability (11.4％),of which 8 were superior dome projections and 1 was inferior dome projection.There were no severe disability,persistent vegetative state,and death.The prognosis in patients with inferior dome projection was better than that of superior dome projection (97.3％ [36/37] vs.76.5％ [26/34]).The difference was statistically significant (χ2=5.19,P<0.05).Conclusions The lateral supraorbital approach is an effective option for treating ruptured ACoAA with different dome projections in acute phase.The prognosis in patients with inferior dome projection is better than that of superior dome projection.
