Acute intestinal obstruction has been treated with surgery in 437 patients in the Laboratory of Abdominal Surgery of our hospital during the rast 20 years. Of these, 40(9.19%) died. This paper analyses the causes of misdiagnosis and death, showing that in over 50% cases, adhesive intestinal obstruction was accompanied by volvulus which often caused intestinal gangrene. Operative history of the abdomen was overemphasized. Preoperative observation lasted too long(over 72 hours), leading to the loss of the chance of operation. In 13 out of 40 dead cases, death was caused by malignant matastases, and in others by suppurative peritonitis due to intestinal perforation, toxic shock, intestinal fistula, etc. It is suggested that emergency surgery be performed as soon as the findings of strangulated intestinal obstruction are noticed. Four measures for diagnosing strangulated intestinal obstruction are discussed.

Five patients with Peutz-Jeghers Syndrome(PJS) have been reported in this paper. One ofthem developed polypous malignancy in the rec-tum, one associated with bladder canaer. The au-thers have once performed multiple operations, in-cluded small bower Roux-Y anastomosis keepedpylorus for a patiet with duodenal obstruction in-duced by polyps. The questions related with surgi-cal management is PJS are discussed principally inthis paper.

Objective To explore the feasibility of carrying out the common imprecision range among different biochemical systems in different laboratories.Methods Biochemical professionals visited 18 third-grade class A hospitals in Hebei Province,investigated the internal quality control data of 21 biochemical tests and made classification according to certain parameter criterias.Data were collected from April to September,2010 and calculated for cumulative mean,standard deviation (s) and CV.Data were compared according to 1/3,1/4 of TEa established by CLIA'88 and allowable CVb％ derived from biological variants.Results Among 18 hospitals,5 (27.8％) set their target value by mean value of 6 months,5(27.8％) by continuous 20 days and 8(44.4％) by the given value of the supplier.CVs of 21biochemical tests were quite different among 18 biochemistry laboratories,in which LDH was 6.79 times and CK was 76.79 times different from one another.35.5％-94.1％ biochemical tests met the requirement of CV ＜ 1/3TEa and 0.0％-91.7％ met the requirement of CV ＜ 1/4TEa.0.0％-94.1％ of tests were below allowable CVb％ 16/21 (76.2％) tests could satisfy the requirement of CV ＜ 1/3TEa.The top five tests which didn't meet the requirements were Na,Urea,TBIL,ALT and Glu.Conclusions The internal quality control among biochemistry laboratories in Hebei Province has not been standardized yet.According to the survey data,biochemistry laboratories of third-grade class A hospitals may set 75％ point of imprecision as a reference.After a period of improvement,we will set common imprecision range among biochemistry laborotories in Hebei Province and even in China.

Objective To evaluate the prognosis in patients with hepatocarcinoma by examining the expression of α-fetoprotein (AFP) and des γ prothrombin (DCP).Methods Retrospectively analyzed the expression of AFP and DCP in 105 patients received curative hepatectomy.Divided the patients into three groups as follow:the tumor markers were both negative pre-and post-operation (Group N) ; the tumor markers decreased to normal after operation (Group D) ; the tumor markers kept positive or decreased but still higher positive after operation (Group P).Then combined the two markers and divided the patients into 4 groups:two markers both negative(AFP + DCP +)(Group A) ; AFP + DCP-(Group B) ; AFP-DCP + (Group C) ; AFP-DCP-(Group D).Results High AFP and DCP levels were significantly associated with poor tumor-free and overall survival.The presence of large size and advanced stage were significantly associated with Group P.Overall survival in the AFP-N group was significantly better than that of other groups and overall survival in DCP-N group were significantly better than that of the P group.After the combination,Group A had the best overall and tumor free survival rate while the D group had the worst.The differences between B and C group were not significant.Conclusions AFP and DCP can be both used solely as tumor markers and the expressions of them are associated with the prognosis.The combination of two markers can be used for better prediction of hepatocarcinoma.

Objective:To observe the efficacy of apatinib combined with capecitabine in the treatment of advanced esophageal cancer.Methods:A total of 101 patients with advanced esophageal cancer in Taixing People's Hospital of Jiangsu Province from June 2017 to February 2018 were enrolled, and all the patients were divided into the control group (50 cases) and the observation group (51 cases) according to the random number table. The control group was treated with capecitabine combined with radiotherapy, and the observation group was treated with apatinib on the basis of the control group. The therapeutic effects, adverse reactions and progression-free survival (PFS) time of the two groups were compared.Results:The overall response rate in the observation group was higher than that in the control group [90.2% (46/51) vs. 72.0% (36/50)], and the difference was statistically significant ( χ2 = 5.473, P = 0.019). There were no significant differences in leukopenia, neutropenia, thrombocytopenia, anemia, proteinuria and hypertension between the two groups (all P > 0.05). The median PFS time in the observation group was 18.49 months (95% CI 15.35-25.03 months), and that in the control group was 13.33 months (95% CI 10.36-18.24 months), and the difference between the two groups was statistically significant ( χ2 = 5.995, P < 0.01). Conclusions:The therapeutic effect of apatinib combined with capecitabine in the treatment of advanced esophageal cancer is accurate. No obvious adverse reaction occurs, and the PFS time is prolonged.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
