Objective To evaluate the outcomes of transanal coloanal pull-through with resection of the internal anal sphincter in neonates and infants with Hirschsprung's disease.Methods Transanal coloanal pull-through with resection of the internal anal sphincter was performed on 101 neonates or infants with Hirschsprung's disease in our hospital.An incision slightly longer than one-half of the rectal circumference was made at the dentate line.Then,the muscular layer of the anterior rectal wall was dissected and separated upwards from the submucosal layer;meanwhile that of the posterior wall was also separated upwards along the rectal longitudinal muscles.After the muscular layer was separated to the level of the peritoneal reflection,a radial operation was performed by resecting the internal anal sphincter and muscle sheath of the posterior rectal wall.Results The operation was accomplished successfully in all the patients with less than 10 ml of intraoperative blood loss.The operation time ranged from 45 to 190 min(mean,90 min).No complications,including urine retention,incision infection,and anastomotic stenosis,occurred.Two patients(2/86,2.3%) developed enterocolitis after the operation.The incidence of fecal soiling was 27%(22/82) at 2 months after the operation,and then decreased to 4%(3/82) at 6 months.Anorectal manometry was performed on 78 patients at 1,2,3,and 6 months postoperatively.The results demonstrated that the anal resting pressure after the operation was significantly lower than that before the operation(P

Objective To identify clinical prognostic predicators and surgery indicator of stage IIIb-T_4 in patients with lung cancer patients whose tumor invaded heart, main vessel or carina. Methods From 1988 to 2000,151 patients with pathological stage IIIb-T_4 lung cancer who underwent resection by Shandong Provincial Hospital were analyzed as control samples, 112 patients with pathological stage IIIa-T_3N_1M_0 who underwent resection at the same time were also analyzed. Factors were estimated from the date of operation using the Kaplan-Meier and Log rank analysis. The Cox regression model evaluated the influence of factors on the survival. Results The median survival period were 26.1 months and the overall of 1-year, 3-year and 5-year survivals of the 151 patients were 73.5%, 33.1% and 16.6% respectively.The significant prognostic factors (P

OBJECTIVE:To provide reference for rational use of human serum albumin for surgical inpatients. METHODS:The utilization of human serum albumin for surgical inpatients in a hospital during Jan.-Mar. 2014 was analyzed and evaluated by UHC Guidelines for the Use of Album,Nonprotein Colloid,and Crystalloid Solutions(2010 edition)and European Immune Globu-lin and Albumin Use Recommendation. RESULTS:Among the 556 patients,totally 895 human serum albumin application were con-ducted,mainly involving development of gastrointestinal surgery(29.7%),hepatobiliary surgery(25.9%)and cardiothoracic sur-gery(13.1%). The main reasons were correcting hypoalbuminemia(62.9%),followed by albumin supplemented during major sur-gery(7.9%)and alleviating ascites in patients with cirrhosis(4.4%);only 95 applications(10.6%)were considered appropriate. The most prevalent inappropriate reason was for correcting hypoalbuminemia. CONCLUSIONS:Human serum albumin in the surgi-cal inpatients in the hospital shows a large amount,and low consistent rate between indications and guidelines. The rational stan-dardized utilization of human serum albumin should be strengthened.

Objective To observe the pathologic changes of ganglion cell and nerve plexus in internal anus sphincter of rats with congenital anorectal malformations (ARM).Methods Healthy and pregnant Wistar-Imammichi rats were induced to ARM by ethylene thiourea (ETU). There were 67 rats with ARM at all. The pelvis was continuously cut from the exactly midsagittal plane. The HE staining was performed, and the numbers of the ganglion cell and nerve plexus in the internal anus sphincter were observed under the microscope.Results The average numbers of the ganglion cell and nerve pluxes in the ARM embryos were (1.206±0.012) and (0.308±0.051). Those of the normal control embryos were (3.710±0.043) and (1.227±0.072) respectively. There was a significant difference between two groups ( P<0.05～0.01). While, those of the embryos without ARM which dealt with ETU were (3.012±0.032) and (1.187±0.004) respectively, didn't differ from the normal control embryos.Conclusion The decrease of the ganglion cell and the nerve plexus in internal anus sphincter is an important pathologic change of ARM.

OBJECTIVE:To systematically review the efficacy and safety of pirfenidone in the treatment of idiopathic pulmo-nary fibrosis (IPF),and provide evidence-based reference for clinical treatment. METHODS:Retrieved from Cochrane Library, PubMed,EMBase,CJFD,CBM,VIP Database and Wanfang Database,randomized controlled trials (RCT) about the efficacy and safety of pirfenidone (test group) versus placebo (control group) in the treatment of IPF were collected,and Meta-analysis was performed by using Rev Man 5.1.7 software after data extracting and quality evaluating by modified Jadad. RESULTS:Totally 4 RCTs were enrolled,involving 1 153 patients. Results of Meta-analysis showed the decrease value of lung capacity [WMD=0.39,95%CI(0.16,0.61), P<0.001] and decrease value of the percentage of forced vital capacity to expected value [RR=0.68, 95%CI(0.53,0.87),P=0.002] in test group were lower than control group,there was significant difference between 2 groups;there was no significant difference in the lowest oxygen saturation [WMD=0.53,95%CI(-0.78,1.84),P=0.43] between 2 groups,however,the results of subgroup analysis showed the remission degree of 1 200 mg/d PFD for the decrease of lowest oxy-gen saturation was superior to placebo group,there was significant difference between 2 groups [WMD=1.72,95%CI(1.33,2.10), P<0.001],but therewas no significant difference between the remission degree of 1800 mg/d and placebo;and there was no signifi-cant difference in the incidence of adverse reactions between 2 groups [RR=1.70,95%CI(0.46,6.31),P=0.43],but the incidence of photosensitivity veactions in test group was significantly higher than that of control group,there was significant difference [RR=9.35,95%CI(4.23,20.67),P<0.001]. CONCLUSIONS:The efficacy of pirfenidone in the treatment of IPF is good,but the inci-dence of photosensitivity reactions should be noticed.

Objective To compare the treatment effects between lymphatic chemotherapy and regional extended release chemotherapy (RERC) for rectal cancer lymph node metastasis. Methods The lymph nodes at or beside colon (first station), beside (second station) and at the root of mesentery blood vessel (third station) of the patients with rectal cancer in control group (20 cases), lymphatic chemotherapy group (20 cases) and RERC group (20 cases) were removed to compare proliferation index (PI), apoptotic index (AI) and AL/PI of cancer cells in the lymph nodes. Results The PI, AI, and AI/PI of cancer cells in correspondent lymph nodes were not statistically different between lymphatic chemotherapy group and the other 2 groups (F=4.973-7.394, 5.372-8.694, 4.527-5.436, P<0.05; t=3.128-7.688, 3.388-9.615, 6.518-13.180, P<0.05). The PI, AI, and AI/PI of cancer cells in the first and second station lymph nodes in RERC group were significantly different from those in control group (t=5.103, 4.927; 6.938, 6.450; 8.839, 9.021; P<0.05), and from those in the third station lymph nodes in RERC group (F=6.572, 8.964, 5.845, P<0.05; t=3.505, 3.353; 5.397, 4.701; 9.039, 8.629; P<0.05). Sorted by the treatment effects for cancer cells in lymph nodes, the first is each station of the lymphatic chemotherapy group, followed by the first and second station of the RERC group, and then the third station of the RERC group which was almost equal to any station of the control group. Conclusion Lymphatic chemotherapy is better than RERC in the treatment of rectal lymph node metastasis in the aspect of scale and degree.
