Objective To study the effect of cholecalciterol cholesterol emulsion(CCE)in the zymosan(Z)-induced acute hepatic injury. Meth-ods A total of 36 C57 BL/6 mice were randomly divided into 4 groups,namely negative control(CON)group,CCE group,Z group and CCE+Z group,respectively. There were 9 mice in each group. Mice from CON group and Z group were fed with pure water. Mice from CCE group and CCE+Z group were fed with cholecalciterol cholesterol emulsion 20μL dissolved in 200 mL pure water which was kept in darkness. After 14 days, Z group and CCE+Z group were injected with zymosan at a dose of 500 mg/kg. After 18 hours,all the mice in each group were sacrificed. The liver tissues were harvested for histopathological examination. The serum ALT levels were determined. The molecular expression of IL-6 and IL-18 in liv-er tissue of mice were evaluated by Western blotting and real-time quantitative PCR method. Results The results of histopathological examination showed that liver tissue damage in CCE+Z group was lighter than that of Z group ,and heavier than that of the CON group. Compared to the CON group,Z group had the highest serum ALT level,followed by CCE+Z group,while in Z group was significantly lower than that in CON group(all P<0.05). The expression of IL-6 and IL-18 protein and mRNA showed level of Z group was apparently higher than those of CON group and CCE+Z group(all P<0.05). Conclusion Cholecalciterol cholesterol emulsion can play certain protective effect on zymosan-induced liver injury in mice.

Objective To investigate the correlation between vitamin A and surfactant protein (SP)-B, SP-C in human body,and to explore the effects on lung development and pulmonary function of neonates. Methods We collected the blood samples of 170 pregnant women and umbilical cord serum of their neonatal babies. The levels of vitamin A in pregnant women and their neonatal babies,and the levels of SP-B and SP-C in neonatal umbilical cord serum were detected by ELISA. We conducted a follow-up by standard telephone questionnaire,which we concerned was the number of respiratory tract infection within six months,in order to assess the neonatal pulmonary functions. Results (1) There was a positive correlation between the vitamin A levels in neonatal umbilical cord blood and in the blood of pregnant women(r=0. 866,P<0. 05). (2) There was a positive correlation between the vitamin A levels in neonatal umbilical cord blood and the levels of SP-B,SP-C in the blood(r=0. 817,P<0. 05). (3)In the follow-up of 170 cases of infants within six months,three cases with pneumonia hospitalized more than once,but no respiratory distress syndrome hap-pened. Conclusion Vitamin A can be used as an important biological marker to evaluate the neonatal pul-monary maturity. If we detect the vitamin A levels of pregnant women,increase the intake of vitamin A,we can improve the content of SP-B,SP-C,improve the development of neonatal lung function in growth.

OBJECTIVETo explore the value of magnetic resonance enterography (MRE) for diagnosis of small intestinal diseases in children.

METHODA total of 92 children who received MRE from July 2009 to January 2014 were included into this study. The clinical value of MRE in children was evaluated by describing the image presentation of MRE based on clinical diagnosis.

RESULTAll the 92 cases (average age was nine year and one month, among whom 61 were boys, and 31 were girls) received MRE examination with good tolerance and had no complications. Eleven cases (12%) did not show good distension of small bowel loop during MRE and could not evaluate the bowel wall pathologies correctly. A total of 66 cases (72%) showed pathological MRE images. All patients with Crohn's disease showed pathological gut and 53% (16/30) showed extramural changes with MRE, 97% (29/30) showed colon lesions with colonoscopy, 73% (20/22) showed small intestine lesions with capsule endoscopy. All patients with intestinal obstruction (7 cases) showed abnormal gut distension, 4 of whom showed obstruction point. Five patients with small intestinal neoplasms showed the mass with MRE. One of the patients with intestinal tuberculosis showed enlarged lymph nodes with ring strengthening. Nine cases with eosinophilic gastroenteritis (75%) and 1 case of gastrointestinal bleeding showed increased contrast enhancement for small bowel. The main finding of MRE were abnormal wall thickening and enhancement, gut stricture, bowel expansion, etc.

CONCLUSIONMRE for children was safe and reliable. It can be a suitable method for determining the location and extent of gut for small intestinal diseases, especially suitable for Crohn's disease in children.

OBJECTIVETo explore the effect of combined preoperative chemotherapy with radiotherapy on locally advanced lower rectal carcinoma.

METHODSThirty- five patients with locally advanced lower rectal carcinoma were received a new regimen of combined preoperative chemotherapy with radiotherapy. Routine fr action of radiation was given with total dose of 46 Gy,2 Gy per fraction,five ti mes a week. Patients received oxaliplatin 130 mg/m(2) (infusion) on day 1, plus leu novorin 200 mg/m(2) and 5- FU 500 mg/m(2)(intravenous bolus) from day 1 to day 3 eve ry 3 weeks for total two cycles before irradiation. Operation was performed 4 to 6 weeks later after neoadjuvant therapy.

RESULTSAfter neoadjuvant therapy,all patients underwent surgical resection with complete pathologic response in 7 patients,average tumor size decrease of in 34.4%, tumor stage decrease in 65.7% o f patients and nodal- negative change rate of 55.6%. Radical resection was per formed in 34 patients,in whom 18 patients received abdominoperineal resection(AP R) and 16 patients received sphincter- preserving surgery with 45.7% of anal preservation rate. One patient received palliative resection. No local recurrence occurred in all patients who received radical resection,but two cases had liver metastasis.

CONCLUSIONCombined preoperative chemotherapy with radiotherapy is a better neoadjuvant therapy for lower advanced rectal cancer,which can decrease tumor stage,improve resectability and anal sphincter preservation rate,therefore ,this new neoadjuvant therapy with tolerable toxicity will has a promising application in the clinical setting.

OBJECTIVETo investigate the prognostic significance of metastatic lymph node ratio in patients with colorectal cancer.

METHODSThe clinicopathological data of 303 surgically treated patients with colorectal cancer were retrospectively analyzed. Spearman correlation analysis was used to determine the correlation coefficient. The survival was analyzed using Kaplan-Meier method, and the survival difference was assessed by Log-rank test. Multivariate analysis was performed using Cox proportional hazard regression model in forward stepwise regression. Receiver working characteristic curve was used to compare the accuracy of the metastatic lymph nodes ratio in predicting the death of patients at 5 years postoperatively with that of the number of metastatic lymph nodes.

RESULTSThe MLR was not correlated with the total number of dissected lymph nodes (Spearman correlation coefficient: -0.099, P > 0.05), but the positive rate of metastatic lymph nodes did (correlation coefficient: 0.107, P < 0.05). Kaplan-Meier survival analysis revealed that the MLR significantly influenced the postoperative survival time (Log-rank chi(2) = 42.878, P < 0.01), even in the patients with less than 12 resected lymph nodes. The 5-year survival rates for rN0, rN1, rN2 and rN3 were 90.9%, 68.9%, 54.7% and 39.4%, respectively. There was a significant difference between the different stages (P < 0.01). Cox proportional hazard regression model analysis showed that the metastatic lymph node ratio was an independent prognostic factor. (EXP(B) = 7.809, P < 0.01). There was no significant difference between metastatic lymph node ratio and the number of metastatic lymph nodes in predicting the death of patients at 5 years postoperatively based on the area under the receiver working characteristic curve.

CONCLUSIONThe metastatic lymph node ratio in colorectal cancer patients is not correlated with the total number of dissected lymph nodes. The metastatic lymph node ratio is a major independent prognostic factor for patients with colorectal cancer. The ability of metastatic lymph node ratio in predicting the death of colorectal cancer patients at 5 years postoperatively is the same as that of the number of metastatic lymph nodes.

OBJECTIVETo investigate clinical effects of coracohumeral ligament reconstruction with autologous double-strand of long palmaris longus tendon and artificial ligament for the treatment of acromioclavicular joint dislocation.

METHODSFrom April 2006 to June 2009, 31 patients with acromioclavicular joint dislocation were treated with coracohumeral ligament reconstruction using autologous double-strand palmaris longus tendon and artificial ligament. There were 18 males and 13 females, ranging in age from 18 to 60 years, with an average of 35 years. Twenty-six patients were acute trauma and other 5 patients were chronic trauma. Preoperative symptoms included different degrees of pain, restricted movement, and instability of acromioclaviecular joint. The X-ray showed acromioclavicular joint dislocation.

RESULTSThe patients had good incision union without vascular and nerve injuries. All the patients were followed up, and the average duration was 23 months. The JOA scores decreased from preoperative (38.8 +/- 1.5) to (73.2 +/- 1.1) at 1 month after operation,and (93.5 +/- 0.8)at the last follow-up. Twenty-eight patients got an excellent result, 2 good and 1 fair.

CONCLUSIONThe reconstruction of coracohumeral ligament using autologous double-strand palmaris longus tendon and artificial ligament is an effective method for the treatment of acromioclavicular joint dislocation.

OBJECTIVETo investigate into the changes of dietary patterns and their impacts on health of urban and rural residents in Jiangsu Province, China during the 1990s.

METHODSOn the basis of the results of food consumption survey, the calorie intake was calculated according to the balanced diet method and the quality of diet was assessed by scores of desirable dietary pattern (DDP).

RESULTSIt was found that food consumption and dietary patterns changed remarkably during the 1990s. Grain consumption was decreasing year by year, but the consumption of animal food was markedly increasing. Although the score of desirable dietary pattern (DDP) in urban residents was more than 90, the deducted score due to over-consumption of animal food increased. The mortality from infectious diseases evidently decreased in the whole province, while the death rates of some chronic diseases, such as diabetes, hypertension, colorectal cancer and breast cancer, were increasing rapidly in urban areas.

CONCLUSIONSSufficient attention should be paid to the negative effects of change in dietary patterns on people's health, especially in the urban residents.

Objective To systematically evaluate the effectiveness and safety of Gegen-Qinlian decoction in treating ulcerative colitis.Methods We searched Cochrane Library, PubMed, CNKI, VIP, CBM and Wanfang online Data bases June, 2017. All of the randomized controlled trials(RCTs) of Gegen-Qinlian decoction compared with sulfasalazine in treating for ulcerative colitis were searched. The quality of RCTs meeting inclusion criteria was evaluated and the data were extracted; meta-analyses were performed with RevMan 5.3 software, and then the GRADE system was used to rate the level of evidence and strength of recommendation.Results Totally 5 RCTs were included into the study. The group treated withGegen-Qinlian decoction or combined with sulfasalazine was superior to the control group in total effective rate (RR=1.18, 95％ CI(1.06-1.30),P=0.002). There were no significant differences between the two groups in clinical symptom curative effect [RR=1.09, 95％CI (0.72-1.64), P=0.69], adverse reactions [RR=0.11, 95％ CI (0.01-1.92),P=0.13], Symptom curative effect [RR=1.33, 95％CI (0.95-1.88),P=0.10], mucosal lesions curative effect [RR=1.33, 95％CI(0.95-1.88), P=0.10]. Based on the GRADE system, the level of total effective rate and adverse reactions evidence was Grade C, and the strength of recommendation was 2. the level of the rest of the evidence was Grade D.Conclusions Compared with sulfasalazine,Gegen-Qinliandecoction or combined with sulfasalazine can be used as a treatment option.

In maintaining normal function and activation processes, glycolysis, lipid metabolism, and amino acid metabolism play key roles in the energy demand of platelets. In the resting state, platelets primarily rely on glycolysis and aerobic oxidation to generate energy. Upon activation, platelets preferentially utilize glycolysis, as it can more rapidly provide the required ATP. In addition to glycolysis, platelets can also utilize glycogen and fatty acids as additional energy sources. The ATP provided by fatty acid oxidation is crucial for platelet activation. Additionally, during platelet storage, distinctive changes in energy metabolism occur. In the early stages of storage, platelets primarily rely on glycolysis and the pentose phosphate pathway (PPP) to generate energy. In the mid-storage phase, there is an increase in tricarboxylic acid cycle (TCA) metabolism. In the later stages of storage, cellular metabolism gradually declines. The regulation and flexibility of these metabolic pathways play a critical role in the survival and function of platelets in different states.
