The segment length,the length of dorsal root attachment of each segment of the spinal cord of 10 adult men were measured.The cross sections from 4 specimens were stained with 1% osmic acid and the area of each section was measured with a com- pensating polar planimeter after being magnified 10 diameters.The segment volume was obtained by multiplying the segment length by the cross-sectlon area. The results shows that the length of spinal cords in Chinese are essentially the same as those from European and Japanese.They are approximately 44cm.in length. The length of each part of the cord in Chinese,European and Japanese were compared. The length of each part of the cord in Chinese and European are essentially alike,but the length of lumbar cord of Japanese appears to be slightly longer. The results show that the weight of the segment was closely related to the segment length. The coronal diameter of each segment is longer than the sagittal diameter,especial- ly it is true in the cervical enlargement.The longest coronal and sagittal diameters are found in the cervical enlargement,the next are in the lumbar enlargement,and the shortest are in the thoracic segment. The volume of the cervical segment and the lumbo-sacral segment is closely rela- ted to their cross-section area particularly to the area of their white matter. The volume of the gray matter of the cervical and the lumbo-sacral segments has a close relation to the gray matter area of the same segment,but that of the thoracic segment is related to its length. It is quite obvious that the volume of the white matter of both the cervical and lumbar enlargements reaches its highest value at segments higher than that of the gray matter,which may indicate that the increase in volume in the gray and white matter are dependent upon each other.

Objective To compare the clinical result of Da Vinci robot-assisted distal pancreatectomy(RDP) and laparoscopic distal pancreatectomy(LDP), and to evaluate the clinical application experience of Da Vinci robotassisted spleen-preserving distal pancreatectomy.Methods From March 2013 to June 2015, totally 12 patients undergone RDP and 22 patients undergone LDP in our department were analyzed retrospectively.Results Intraoperative blood loss, hospitalization duration and postoperative fast time in RDP group was less than that in LDP group, the spleen-preserving rate and hospitalization expenses were higher in RDP group(P < 0.05).There was no statistically significant difference in the rate of surgery duration and incidence of postoperative complication between two groups (P > 0.05).The following-up period was 1-28 months with a mean of (9.94 ± 8.99) months, 1 case of peritoneal infection occurred in RDP group, 1 case of survival with tumor recurrence and 3 case suffered peritoneal infection in LDP group.Others were no metastasis, recurrence or death.Conclusions RDP is safe and feasible, the short-term prognosis is better than that of LDP.It has advantages of cleat 3 D visual field, stability in control,less invasive,and quick recovery.It is worth further clinical use.

Objective To investigate the effect of palliative surgical treatment and minimally invasive biliary drainage of hilar cholangiocarcinoma.Methods Retrospectively collected 244 hilar cholangiocarcinoma patients clinical data in Affiliated Hospital of Qiingdao University between Jan.1,2008 to Dec.31,2011.Survival accoding to different treatment methods was compared using Kaplan-Meier method.The continuous measurement data were analyzed using the one-way ANOVA and the U test.The categorical variable were analyzed using the chi-square test or Fisher exact test.Result Among 244 patients, the R1/R2 resection group in 93 patients, the endoscopic retrograde biviar drainage group in 69 patients, the percutaneous transhepatic cholangial drainage group in 82 patiens.Three groups of median survival time and l-, 2-, 3-year survival rate and median survival time were (13.5 months, 8.9 months, 8.6 months), (63.0%, 24.7%, 7.4%), (33.3%, 3.3%, 0), (32.4%,4.2%, 0), respectively.There was significant difference in the survival time between R1/R2-resections and endoscopic retrograde biviary drainage treatments (P < 0.001).R1/R2-resections and percutaneous transhepatic cholangial drainage treatments were statistical differences in survival time (P < 0.001).Endoscopic retrograde biviary drainage and percutaneous transhepatic cholangial drainage treatments were no statistical differences in survival time (P =0.971).Conclusions Palliative surgical treatment for hilar cholangiocarcinoma patients had a more significant effect.Endoscopic retrograde biviary drainage and percutaneous transhepatic cholangial drainage of minimally invasive jaundice reducing method for prognosis in patients with hilar cholangiocarcinoma was same.

Objective To analyse the possible reasons of early hydrocephalus after surgery for posterior cranial fossa tumors,and put forward the preventive messures against this complication.Methods Clinical data of 18 cases of early hydrocephalus after surgery for posterior cranial fossa tumors were analysed retrospectively.Results All the patients were in good state within 24 hours after surgery,but a series of symptoms,such as disturbance of consciousness,headache and vomiting,occurred.CT scanning showed hydrocephalus.After the comprehensive treatment including ventricular duainage,16 patients were healed.2 cases died.Conclusions Post-operative cerebellar edema,intracranial hematoma or hydrops,residual tumor,might be the possible cause of this disease.Preventive messures against this complication might include protecting brain tissues during operations,hemostasis and comprehensive treatment after operations.

ObjectiveTo observe the changes of high sensitive serum C-reaction protein (hsCRP) in macrovascular disease with or without type 2 diabetes.MethodsThere were 3 groups population in our study:148 type 2 diabetic patients were divided into 2 subgroups:77 patients with macrovascular disease and 71 without macrovascular disease, 73 non-diabetic patients with macrovascular disease and 75 health controls. The concentration of serum hsCRP of all patients were determined by ELISA.ResultsThere was significant difference in concentration of serum hsCRP between type 2 diabetes with or without macrovascular disease groups, non-diabetes macrovascular disease group and control(P<0.01 or P<0.001). However, there was not significant difference between 2 diabetes groups and non- diabetic macrovascular disease group(P>0.05). There was no significant difference in hsCRP between type 2 diabetes with and without macrovascular disease (P>0.05).ConclusionThere may be a chronic inflammatory reaction in patients with type 2 diabetes or macrovascular disease. hsCRP might be a well forecasting factor of the occurrence and development of type 2 diabetes and atherosclerosis.

Nine cases of mesenteric desmoid-type fibromatosis were diagnosed and treated in Taizhou Hospital, Wenzhou Medical University between January 2010 and May 2022, including 2 females and 7 males, aged 16 to 59 years. The lesions were in the mesentery of small intestine with 7 cases, ileocecal junction with 1 cases and transverse colon with 1 case. The tumors had an unclear boundary and no envelope, the section was solid, gray and tough. The mean maximum diameter was (10.7±8.5) cm (range 3.5-33.0 cm). Microscopically, fusiform fibroblasts and myofibroblasts were parallel, bunched or staggered, buried in a large amount of extracellular collagen. The cell morphology was relatively consistent, without obvious atypia, and mitosis was rare. Immunohistochemistry showed that the tumor cells were positive for vimentin (9/9), β-catenin (9/9), while smooth muscle actin (5/9) stains were focally positive. Ki-67 proliferation index was 1%-10%. Cytokeratin Pan, S-100, STAT6, CD117, DOG1, CD34, desmin and anaplastic lymphoma kinase stains were negative. Genetic analysis showed that there were 7 cases of c.121G>A(p.Thr41Ala) mutation of CTNNB1 gene, 1 case of c.121G>A(p.Thr41Ala) and 1 case of c.134C>T(p.Ser45Phe) double mutation, and 1 case of wild type. Tumors were surgically resected in all 9 cases. Eight cases had no recurrence or metastasis, 1 case had recurrence 6 months later, and no recurrence or metastasis after additional surgical resection.
