Objective:To investigate the effect of early enteral nutrition combined with Bacillus in the treatment of patients with digestive tract perforation.Methods:59 patients with emergency digestive tract perforation were randomly divided into experimental group (EN plus Bacillus,n =31) and control group (TPN,n =28).The patients in the experimental group were given enteral nutrition plus Bacillus after first days (＜ 24 h),and the control group was treated with parenteral nutrition support on the first day after surgery.The average hospitalization time,length of ICU stay,incidence of complications,and serum C-reactive protein in the two groups were analyzed.Results:The average length of hospitalization time,ICU stay,recovery of bowel function and eating time were significantly shorter in the experimental group than in the control group(P ＜ 0.05).There was no significant difference in nutrition index between the two groups during the perioperative period (P ＞ 0.05).The C-reactive protein in the experimental group was significantly lower than that in the control group fourth days after operation (P ＜ 0.05).The incidence of postoperative wound infection in the experimental group was significantly lower than that of the control group (P ＜ 0.05).There was no significant difference in the incidence of other complications.Conclusion:Early administration of enteral nutrition combined with Bacillus can significantly shorten the intestinal function recovery time,decreasethe average hospitalization days,reduce the postoperative wound infection rate and thus improve the outcome of patients with digestive tract perforation.

Objective To explore the clinical feature,suitable treatment and prognosis of soft tissue leiomyosarcoma of the trunk and extremities.Methods Clinical data of 18 cases of pathologically confirmed soft tissue leiomyosarcoma of the trunk and extremities from January 1999 to December 2012 were analyzed retrospectively.Primary tumors in 7 cases were marginally excised before admitted to our hospital,2 had open biopsy before admission to our hospital,and 8 cases had local relapse at admission; Only one patient took our institute as the first visit.Seventeen cases were performed extended excision of tumors and 1 case underwent marginal resection.All the patients were followed up and the follow-up period was from 16 to 158 months.Results During follow-up period,9 patients developed lung metastasis,and local recurrence occurred in 5 patients.Ten patients died and 8 survived.Of the ten dead cases,seven died of tumor progression and 3 died from non-tumor factors.In the 8 patients survived,2 survived with tumor.The 5-year overall survival rate was 59.2％.Conclusion Soft tissue leiomyosarcoma of the trunk and extremities are rare malignant tumors,mostly occurred in elder patients and presenting soft tissue mass.Local recurrence and distant metastasis are common and associated with a poor prognosis.Surgical excision combined with adjuvant radiation is the common treatment strategy.

Objective To evaluate the value of intermittent splenic artery occlusion in the treatment of iatrogenic splenic injury and the cause of ischemia reperfusion injury.Methods Experimental animals using dogs were divided into experimental group and control group according to whether the splenic artery was blocked.The animal model of iatrogenic splenic injury was established by general anesthesia.Experimental group was treated with intermittent splenic artery blockage combined with gelatin sponge oppression of the wound to stop bleeding.The first time of splenic artery occlusion was 15 min and continued for 10 min and for another 5 rmin if still bleeding.Then hemostatic effect after removing blocking and oppression was observed.Control group was only treated with gelatin sponge compression to stop bleeding.Blood samples and tissue samples were collected before blocking and after reperfusion for 2 hours in experimental group,and before compression and relieving the compression for 2 hours in control group.IL-1 (interleukin),SOD (superoxide disproportionation enzyme),MPO (myeloperoxidase),MDA (malondialdehyde) and caspase-3 (aspartame acid cysteine protease) were detected.Results The control group still had bleeding,while the experimental group had successfully stopped bleeding.Serum markers before and after occlusion in the experinental group were IL-1 (124.4 ± 106.8 vs.121.2 ± 105.1),SOD (4.7 ± 2.7 vs.5.2 ± 1.8) and MDA (8.8 ±6.5 vs10.8 ±7.5).There were no significant differences on serum markers in two groups after occlusion/oppression including IL-1 (121.2 ± 105.1 vs.162.8 ± 73.8),SOD (5.2 ± 1.8 vs.4.7 ± 2.8) and MDA (10.8 ±7.5 vs.9.6 ±6.6) (P＞0.05).Histological indicators before and after occlusion in the experimental group included MPO (0.62 ±0.23 vs.0.68 ±0.21) and Caspase-3 (0.90 ±0.29 vs.0.86 ± 0.26),and there was no statistical difference on MPO (0.68 ±0.21 vs.0.86 ±0.23 after two sets of experiments) and Caspase-3 level (0.86 ± 0.26 vs.1.21 ± 0.18) (P ＞ 0.05) in two groups after occlusion/ oppression.Conclusion The therapeutic effect of intermittent splenic artery occlusion combined with gelatin sponge compression hemostasis is safe and effective and without obvious ischemia reperfusion injury.

Objective To explore the indications and clinical effects of simultaneous mandibular angleplasty on the unaffected side, performed using preformed titanium mesh combined with mandibular angle bone graft, for the treatment of hemifacial microsomia (HFM). Methods The study group included 11 patients between 2013 and 2021 with HFM who underwent simultaneous mandibular angle reduction of the unaffected side and augmentation of the affected side using resected bone scaffolds within the titanium mesh. A series of mandibular linear measurements such as ramus height(RH)and mandibular body length(BL), angular measurements, and asymmetry index combined with clinical photographs and postoperative complications were used to assess the therapeutic effect. Results Postoperatively, all patients were satisfied. Significant improvement in mandibular contour was shown, with no obvious complications. Postoperative data, such as BL and angular measurements, showed no statistically significant differences(P>0.05) between the affected and unaffected sides with improvement in symmetry, except for RH(P<0.05). The preoperative and postoperative asymmetry index were (17.11±4.56)% and (4.81±1.73)%, respectively, with significant improvement(P=0.002). Conclusion This approach provides satisfactory results and significantly improves facial asymmetries for unilateral HFM with hypertrophy of the contralateral mandibular angle.

Objective To observe expression of resistin gene in adipose tissue of SD rats fed with high-fat diet and its correlation to insulin resistance, diabetes mellitus and leptin. Methods Using RT-PCR to mRNA from adipose tissue, the products were obtained, purified, constructed and squenced. Once its squence was verified, semi-quantitative RT-PCR and Northern Blot were employed to study its expressions in adipose tissues of rats with different diets. Oral glucose tolerance test and insulin release test were performed in 2 groups of rats. Results (1) The resistin gene was successfully constructed and sequenced, which was in accordance with the data of genbank. (2) Compared with the control, the expression of resistin in adipose tissue of high-fat diet rats was significantly enhanced, and blood glucose, serum insulin and leptin levels were also elevated in high-fat diet rats (P

Objective To observe the effect of berberine on glucose transport in 3T3-L1 adipocytes and to investigate its mechanism. Methods The glucose consumption of the cells was determined by the glucose oxidase method. The glucose transportation rate of the cells was assayed by the uptake of 2-deoxy-〔 3H〕-D-glucose. Protein kinase B (Akt) activity was detected by immunoprecipitation and Western blot. The gene expression of c-Cbl-associated protein (CAP) was detected by Northern blot. Results 0.1～200 ?mol/L berberine significantly increased glucose consumption in 3T3-L1 adipocytes with a dose-dependent effect, which was independent of insulin. The glucose transportation was significantly increased in adipocytes incubated with 0.1～10 ?mol/L berberine; the action began at 2 h and reached a peak value at 12 h. The results of immunoprecipitation and Western blot showed that berberine did not enhance Akt activity. The result of Northern blot indicated that berberine significantly decreased CAP mRNA expression. Conclusion Adipocytes are the important target cells of berberine. Berberine significantly increases glucose transportation and consumption in adipocytes, the action appeares to be independent of insulin signal pathway.

OBJECTIVETo optimize pre-coated multiple-probe fluorescence in situ hybridization (FISH) to improve its efficiency in cytogenetic diagnosis of acute leukemia.

METHODSThe original multiple-probe FISH techniques were optimized by adjusting the cell density and adding a process of protease digestion. Cytogenetic anomalies were detected in 141 patients with acute lymphocytic leukemia (ALL) or acute myeloid leukemia/ myelodysplastic syndromes (AML/MDS) using the modified technique, and 35 of the patients were also examined using the original technique. The successful detection rate and positive site detection rate were compared between the modified and original techniques.

RESULTSModification of the pre-coated multiple-probe FISH technique resulted in an significant increase of the successful detection rate (from 85.3% to 100%) and the positive site detection rate (from 5.1% to 8.6%) in ALL patients; in AML/MDS patients, the successful detection rate was significantly improved from 67.4% to 99.8% and the positive site detection rate from 3.5% to 6.0% (P<0.01).

CONCLUSIONThe modified pre-coated multiple-probe FISH technique can significantly increase the diagnostic efficiency of cytogenetic abnormalities in leukemic patients.

Objective:To explore the mechanism of Dahuangfuzi decoction on intestinal motility disorder by observing its effect on serum motilin, Cajal interstitial cells and motilin receptor in rats with severe acute pancreatitis (SAP).Methods:Eighteen clean male Sprague-Dawley rats were randomly divided into the control group, SAP group and Dahuangfuzi group ( n=6 each group). The SAP rat model was prepared by retrogradely injected 4% sodium taurocholate into cholangiopancreatic duct. The rats in the SAP group were given 2 mL normal saline (37℃) enema at 12 and 24 h after operation. The rats in the Dahuangfuzi group was given 2 mL Dahuangfuzi decoction (37℃) enema at 12 and 24 h respectively. For the control group, the pancreas was exposed in the same way and then the abdomen was closed. Forty-eight h after operation, the abdominal aorta blood samples were taken for determination of serum endotoxin and amylase, and for detection of serum motilin by enzyme-linked immunosorbent assay (ELISA); the pathological changes of pancreas and ileum were observed by hematoxylin-eosin (HE) staining. The expression of c-kit and motilin receptor protein in ICC in ileum tissue was detected by immunohistochemistry. Results:Compared with the control group, the levels of serum endotoxin and amylase in the SAP group were significantly higher [(504.98±88.81) pg/mL vs. (17.76±5.01) pg/mL; (532.28±66.53) vs. (69.45±3.61) U/L, P<0.05], while the levels of serum motilin were significantly lower [(195.4±6.7) ng/L vs. (301±8.10) ng/L, P<0.05], and the scores of c-kit and motilin receptor protein were decreased ( P<0.05); compared with the SAP group, the levels of serum endotoxin and amylase in the Dahuangfuzi group were significantly reduced [(189.9±38.23) pg/mL vs. (504.98±88.81) pg/mL; (294.23±25.66) vs. (532.28±66.53) U/L, P<0.05], while the levels of serum motilin were significantly increased [(264.2±8.3) ng/L vs. (195.4±6.7) ng/L, P<0.05], and the scores of c-kit and motilin receptor protein were increased ( P<0.05). Conclusions:Dahuangfuzi decoction can improve the intestinal motility of SAP rats by promoting the secretion of motilin, increasing the activity of ICC cells and the expression of motilin receptor.
