Objective To evaluate the therapeutic efficacy of neoadjuvant chemotherapy in cervical carcinoma. Methods TAC(DDP, EPI and BLM) was applied in 68 patients with cervical carcinoma. Therapeutic efficacy and side effects were documented. Results After 1～3 cycles of neoadjuvant chemotherapy, clinical symptoms remission rares reached 100% ,response rate were 100% (40/40) in Ⅰ b～Ⅱ a,90.9% (20/22) in Ⅱ b and 50% (2/4)in Ⅲ a, respectively. Radical resection reached 91.2 %, and only 6 patients of advanced disease failed to radical resection and turned to radiotherapy. Conclusion Neoadjuvant chemotherapy is a safe and effective therapeutic option which could alleviate clinical symptoms, decrease tumor size, down-staging and increase the radical resection rate.

Objective To study the effect of small diameter graft (0.8 cm) splenocaval or mesocaval shunts combined with pericardial devascularization in the treatment of portal hypertensive variceal bleeding. Methods Splenocaval shunts were performed in 14 patients and mesocaval shunts were done in 24 patients, in combination with pericardial devascularization. Results The average decrease of free portal pressure was 6.6±1.2 cm. There was no significant changes in liver function postoperatively (P>0.05). Platelet counts and leukocyte counts were back to normal in splenocaval shunt patients postoperatively (P< 0.05). Operative mortality was 3%. Pyrexia developed in 4 patients, intractable ascites in 1 patient, chylons ascites in 1 patient, hepatic encephalopathy in 1 patient, intraabdominal infection in 1 patient and stress ulceration in 1 patient. All patients recovered after expectant treatment except one who died from severe intraabdominal infection. 35 patients received follow-up between 6 months and 3 years, total effective rate was 89%, 2 patients died from recurrent variceal bleeding, the shunt potency rate was 80% in 1 year and 75% in 3 years. Esophagogastric varices disappeared or alleviated as shown by endoscopy in 25 patients on 6 months postoperatively. Conclusions Small diameter portosystemic graft shunts combined with poricardial devascularization is an effective therapy for bleeding esophagogastric varices with a low rate of hepatic encephalopathy. Splenocaval shunt alleviates hypersplenism concurrently.

Background and purpose:It has been confirmed that homozygous deletion of p16/p15 gene and its co-deletion of p16/p15 genes were related to the occurrence, progress and prognosis of epithelial ovarian cancer. However, the mono-deletion and co-deletion of the genes has been detected with tissue but not in serum DNA of the epithelial ovarian cancer. In this article, we studied the relationship between homozygous deletion of p16/p15 gene and its co-deletion of p16/p15 genes in serum DNA of the epithelial ovarian cancer.Methods:Primers were used to amplify exon 2 of p16 and exon 2 of p15 gene by polymerase chain reaction. Homozygous deletions of the p16, p15 and co-deletion of p16/p15 genes were studied in either serum DNA of 165 patients with epithelial ovarian cancer, their counterpart lymphocytes DNA, serum DNA of 25 benign ovarian cyst or of 15 health donors.Results:The homozygous deletion rates of either p15 or p16 gene were 27.9%(46/165)and 27.3%(45/165)serum DNA in the patients with epithelial ovarian cancer respectively, while the co-deletion rate of p16/p15 genes was 24.2% (40/165). However, the deletions of p15/p16 genes and its co-deletion were not found in serum DNA of the counterpart lymphocytes,25 benign ovarian cyst and 15 health donors (The P values were 0.000、0.000 and 0.000 respectively). The deletions of either p15 or p16 gene for the patients with stage Ⅰ~Ⅱ were 14.3%(5/35) and 11.4%(4/35), 33.3%(25/75) and 32.0%(24/75) for the patients with stage Ⅲ, 29.1%(16/55) and 30.9% (17/55) for stage Ⅳ, respectively. Although there was no significant differences among the groups, the deletion of p15 and p16 genes in the patients with advanced stage were higher than that with early stage. The deletion was not found to be associated with histopathology of epithelial ovarian cancer.Conclusions:Homozygous deletions of the p16, p15 genes and its co-deletion of p15/p16 genes were commonly found in the serum DNA of epithelial ovarian cancer and might be associated with clinical stage of the disease. It was suggested that detection with serum DNA may be used as a micro-invasive approach and the deletion of genes might served as biological markers for the development and prognosis of the patients with epithelial ovarian cancer.

Objective Investigate the frequency of loss of heterozygosity (LOH) at chromosome arm the short arm chromosome 3p14,25 in the serum DNA from ovarian cancer and its clinical application Methods Thirty eight ovarian cancer serum samples with 18 corresponding tumor tissues and 8 benign ovarian tumors were obtained,and DNA samples extracted from serum and tissue were examined for 3p14,25 LOH by using of polymerase chain reaction with four polymorphic microsatellite markers (D3S1029, D3S1228, D3S1300, D3S1481) Results Matched serum and tissue DNAs from 18 ovarian cancer patients showed significant concordance of 3p14,25 LOH ( P

BACKGROUND:Reduction quality is essential for the healing and function of limb. Traditional X-ray and CT scans have some limitationsin quantitatively and visualy observing the reduction quality of the remnant fracture in three-dimensional displacements. Mimics have advantages in bone rapid modeling and three-dimensional measurement, which offers the chance in quantifying the reduction quality of the displacement in three-dimensional methods.
OBJECTIVE:To measure residual displacement in femoral neck fracture patients with satisfactory reduction by using three-dimensional measurement method, and to evaluate the association between residual displacement and femoral head necrosis.
METHODS:We enroled 141 patients with femoral neck fracture, who were treated in the Third Department of Joint, Affiliated Hospital of Logistics University of People’s Armed Police Force from January 2012 to December 2013. Al patients were divided into undisplaced fracture group (n=44; Garden1&2) and displaced fracture group (n=97; Garden3&4). Based on DICOM data of CT files, three-dimensional models were constructed in each patient. Three parameters were measured: displacement of femoral head’s center, fossa capitis femoris and rotational displacement. Femoral head necrosis was folowed up. The correlation between residual displacement and femoral head necrosis was explored.
RESULTS AND CONCLUSION:(1) The duration of folow-up in those patients ranged from 25 to 43 months. Femoral head necrosis occurred in 7 cases from the undisplaced fracture group and 21 cases from the displaced fracture group. (2) The three parameters (displacement of femoral head’s center, fossa capitis femoris and rotational displacement) were respectively (7.44±2.84) mm, (11.75±4.12) mm and (17.68±8.99)° in the undisplaced group, and (6.51±3.75) mm, (9.34±5.27) mm and (14.67±7.43)° in the displaced group. Except displacement of femoral head’s center, significant differences in the other two parameters were detected between the two groups (P< 0.05). (3) These findings suggest that poor reduction quality is the main factor causing femoral head necrosis. X ray is insufficient to describe the spatial shift and the angle, and has limitations in assessing the reductionquality of femoral neck fracture. Three-dimensional measurement has certain advantages to assess quality of fracture reduction.

Objective To evaluate the efficiency and safety of ultrasonic debridement therapy (UDT) and intelligence negative-pressure wound therapy(INPWT) for diabetic foot ulcers with Wagner 2-3degree.Methods Eighty patients with diabetic foot ulcers with Wagner 2-3 degree were divided into two groups according to the treatment method.The UDT and INPWT group (INPWT group) had 53 cases.Routine treatment group(routine group) had 27 cases.Both groups were given blood sugar and blood pressure control,anticoagulation,anti-infection and supportive treatment.The efficiency and complications were compared between two groups.Results In INPWT group,29 cases were healed,14 cases showed obvious effectiveness,7 cases were effective and 3 cases were inefficacy.The total effective rate was 94.34％(50/53).For routine group,they were 7,8,6,6 cases and 77.78％(21/27) respectively.The total effective rate between two groups had significant difference (P ＜0.05).Pain was found in 9 cases and hemoglobin decreased in 1 case in INPWT group.Conclusion INPWT after UDT for diabetic foot ulcers with Wagner 2-3 degree shows a good efficiency and safety.

Objective To explore the therapeutic effect,advantages and shortcomings of pleural effusion controlled by interrupted drainage via central venous catheter.Methods The research group had 52 cases with pleural effusion controHed by interrupted drainage via central venous catheter,and the control group had 50 cases with pleural effusion controlled by conventional pleuracentesis.Pleural effusion disappearing time,average hospitalization time,pleuracentesis frequency,related therapy expenses and complications of two groups were observed and compared.Results The pleuracentesis frequency,pleural effusion disappearing time,average hospitalization time,related therapy expenses and per capita incidence of complications of the research group were(1.06±1.30)times,(4.31±2.20)days,(9.87±2.30)days,(264.77±37.20)yuan and 9.62%and in the control group were(4.20±2.60)times,(9.92±3.70)days,(15.08±5.80)days,(487.62±55.56)yuan and 38.00%.The differences between two groups were particularly remarkable.Conclusion The method of pleural effusion controlled by interruptod drainage via central venous catheter is safe,eonvenient,economical and microtraumatic,and it is worth using more widely.

To investigate the effects of rennin angiotensin system blockade on the microvessel density in islets of diabetic rats and its relationship with islet function, diabetes model was created by feeding of high-caloric laboratory chow plus intraperitoneal injection of a small dose of streptozotocin (30 mg/kg). After 8 weeks intervention with perindopril (AE, n=10) or valsartan (AR, n=10), the islet function of the animals was evaluated by intravenous insulin release test (IVIRT). The pancreases were immunohistochemically stained to analyze the content of insulin and vascular endothelial growth factor (VEGF) in the islets. The microvessel density (MVD) of islets was detected by counting CD34 positive cells. The hypoxia inducible factor (HIF)-1alpha mRNA expression in the islets was detected by RT-PCR. Compared with normal control group (NC, n=10), the area under the curve for insulin from 0 to 30 min (AUCI(0-30)) of diabetes group (DM, n=8) was decreased by 66.3%; the insulin relative concentration (IRC) of betacell was decreased significantly; the relative content of VEGF was increased obviously [(-4.21+/-0.13) vs (-4.06+/-0.29)]; MVD in islets was decreased by 71.4%; the relative expression of HIF-1alpha mRNA was increased by 1.19 times (all P<0.01). Compared with DM group, the AUCI(0-30) of AE and AR group was increased by 44.6% and 34.9% respectively; IRC was also increased significantly; the relative content of VEGF was decreased by 21.2% and 21.7% respectively; MVD was increased by 62.5% and 75.0% respectively; the relative expression of HIF-1alpha was decreased by 27.2% and 29.0% respectively (all P<0.01 or P<0.05). There were no significant differences in the said indexes between group AE and AR. It is concluded that the blockade of RAS may ameliorate islets function of diabetic rats by increasing the MVD in islets.

Objective To study the pros and cons of two methods of infusing itraconazole injectionand prevent the blockage of peripherally inserted central catheter (PICC) and improve patients' satisfaction with nursing technology.Methods 172 patients infusing itraconazole were divided into two groups by random digital table method.86 cases established an independent infusion pathway as the control group,another 86 cases using PICC for itraconazole injection and withdrawing plunger of the syringe about 0.5 ml before and after the infusion and then pulsing-flushing it with 10 ml normal saline as the experimental group.Then compared the blockage rate of PICC and the patients' satisfaction with nursing technology.Results The blockage rate of the two groups had no significant difference (x2 =0.206,P ＞ 0.05) while patients' satisfaction with nursing skills was distinct,and the experimental group's was 96.51％ (83/86),much higher than 16.28％ (14/86) of the control group.Conclusions Withdrawing taken before and after the infusion of itraconazole injection could effectively prevent catheter blockage and improve patients' satisfaction with nursing technology.

The expression of musclin gene in skeletal muscle of rats fed with high-fat diet and its correlation to insulin resistance.diabetes mellitus and GLUT4 were explored.The results showed that musclin expressin was up-regulated(1.39±0.36 vs 0.31±0.07,P<0.01)in skeletal muscle of rats fed with high-fat diet, suggesting that this finding may be related with insulin resistance and involvement of GLUT-4 expression(1.27 4± 0.32 vs 1.84±0.24.P<0.01).
