Objective To explore the value of multi-slice computed tomography (MSCT) on the typing and staging of bronchiolitis obliterans (BO) in children.Methods Twenty-eight BO patients were recruited and underwent X-ray and MSCT from August 2012 to August 2015.The classification of MSCT signs and radiological manifestations in different stages of BO were discussed.Results Mosaic sign and bronchial wall thickening appeared in all cases and pulmonary atelectasis in 6 patients.MSCT signs were divided into 18 cascs of simple type and 10 of pneumonic type,respectively.Radiological imaging undergone after treatment for 2 ～ 4 weeks indicated that 20 patients turned normal,but 8 patients to chronic stage,including pulmonary interstitial fibrosis (7 cases),bronchoiectasis (6 cases),calcification in bronchial distal (3 cases) and pleural adhesions (2 cases).Conclusion Mosaic sign is a distinctive MSCT manifestation for BO in early phase,and CT typing and staging contribute to guiding the treatment.

Objective: To evaluate the clinical effects of stripping resection plus hemorrhoidal artery ligation columnar suture in treatment of mixed hemorrhoids and Maren Soft Capsule in prevention and treatment of constipation after operation. Methods: Sixty patients were selected as control group A, treated with external dissection and internal ligation, and guided in diet and psychology after operation; sixty patients were selected as control group B, treated with peel resection hemorrhoid artery ligation suture, and guided in diet and psychology after operation; sixty patients were selected as observation group, and the operation method was the same as that of the control group B, but taking Maren Soft Capsule after operation, 2 capsules each time, twice daily. The effects and defecation after operation of patients in the three groups were compared. Results: The recovery rates and postoperative complications of patients in the three groups were compared, and there was no obvious difference between the observation group and the control group B, but there was significant difference in the observation group compared to the control group A (P < 0.05); The defecation after operation in the observation group was better than those in the control groups A and B (P < 0.05). Conclusion: Using stripping resection plus hemorrhoidal artery ligation columnar suture in the treatment of mixed hemorrhoids could achieve good results, with fewer complications after surgery, and it is a good way to treat the mixed hemorrhoids. Maren Soft Capsule could effectively prevent constipation after operation and reduce pain and other symptoms caused by defecation.

Objective To evaluate the diagnosis and treatment of acute superior mesenteric venous thrombosis (ASMVT).Methods Clinical data of 36 ASMVT patients admitted to our department from Jan 2014 to Oct 2017 were retrospectively analyzed,the differences of the clinical data and prognosis of nonsurgical group and surgical group were studied.Results All patients received anticoagulation therapy immediately after diagnosis,and recanalization rate was 42％.Surgical group included 21 cases,of which 9 cases received emergency surgery,12 cases received delayed bowel resection.There was significant difference between non-surgical group and surgical group (P ＞ 0.05) in hemoglobin level at admission (124 ±29)g/L vs.(93 ± 13) g/L,t =3.880,P =0.006.Compared with delayed bowel resection group emergency surgery group had longer bowel resection (65 ± 58) cm vs.(13 ± 6) cm,t =2.700,P =0.035,more loop ileostomy (6 vs.1,x2 =7.875,P =0.016),more postoperative complication rate (56％ vs.8％,x2 =5.619,P =0.046),but there was no significant difference in hospitalization time,hospitalization cost,postoperative recurrence and mortality rate (P ＞ 0.05).Conclusions Early anticoagulantion therapy is advised for ASMVT patients to avoid bowel resection or reduce the length of intestinal resection.It is advisable for those who can be tided over to delayed bowel resection with intestinal obstruction.

The incidence of adenocarcinoma of esophagogastric junction (AEG) is increasing at home and abroad, and surgical treatment is still the main treatment. At present, subtypes of AEG mainly include Siewert and Nishi types. According to the location and stage of the tumor, the appropriate surgical approaches and methods are different, and with the application of minimally invasive technologies such as laparoscopy and robot assisted surgery, there is a certain impact on the occurrence of postoperative complications. However, the postoperative complications of AEG have not been explained in detail. This article will review and summarize the research progress of different surgical methods for AEG postoperative complications, in order to provide some reference for clinical treatment.

Objective To explore the effect of Tuina combined with treadmill training on nerve regeneration after sciatic nerve transection. Methods Ninty-six Sprague-Dawley rats were randomly divided into normal group (n=32), model group (n=32) and treatment group (n=32). The sciatic nerve was transected and the epineurium was sutured in the latter two groups. The treatment group was given Tuina manipulation and treadmill training once a day. Eight rats from each group were detected their sciatic nerve conduction velocity (NCV), the number of axons and Schwann cells (SCs) two, three, four and eight weeks after intervention. Results Compared with the model group, the NCV accelerated in the treatment group four and eight weeks after intervention (P<0.05); while the number of axons was significantly different two and four weeks after intervention (P<0.05), and the number of SCs was not very different between the treatment group and the model group after intervention (P>0.05). Conclusion Tuina combined with treadmill training may promote the regeneration of peripheral nerve after injury in rats.
