Small cell carcinoma of cervix (SCCC) is a rare and high malignant neuroendocrine tumor.Because of its strong invasion,metastasis in early stage and easy recurrence,the prognosis is poor.Its diagnosis is based on pathomorphology,and immune-histochemistry biomarkers can improve its diagnosis.Combined therapy is recommended.Postoperative platinum/etoposide (PE),vincristine/adriamycin/cyclophosphamide (VAC) or taxel/carboplatin(TP) chemotherapy can improve the prognosis.

Background and purpose:To evaluate the treatment regimens used for patients with yolk sac tumors of the ovary and prognostic factors in our hospital. Methods:Clinical data for the patients with yolk sac tumors of the ovary were analyzed retrospectively. Patients were divided into four groups: patients in A group received nonsparing surgery and platinum-based chemotherapy; in B group received nonsparing surgery and non-platinum-based chemotherapy; in C group received fertility-sparing surgery and platinum-based chemotherapy; in D group received fertility-sparing surgery and non-platinum-based chemotherapy. 5-year survival rate and prognostic factors were analyzed.Results:The overall 5- year survival rate was 69.2 %. The 5- years survival rates were 81.8 %, 40.0 %, 82.6% and 50.0% for A, B, C and D group, respectively. Platinum-based chemotherapy achieved significant survival benefit (82.4% vs. 44.4%, P0.05). Clinical stage, the size of residual tumor and Platinum-based chemotherapy were the mainly prognostic factors in multianalysis.Conclusions:Fertility-sparing surgery with a postoperative plainum-based chemotherapy should be the ideal modality for the treatment of yolk sac tumors of the ovary. Staging and tumor-reductive surgery were most associated with the prognosis of the patients.

Objective To investigate the clinicopathologic features,the complications of splenectomy and the survival of epithelial ovarian cancer patients with splenic metastasis.Methods A retrospective study was performed of 32 pailents with epithelial ovarian cancer who underwent splenectomy for tumor cytoreduction at Zhejiang Cancer Hospital between Jan 1998 and Jun 2006.Results Of 32 patients,23 patients(72%)were serous adenocarcinoma and 9 were non-serous adenocarcinoma.According to pathological grade,none was of G1,11 were of G2,21 were of G3.Postoperatively,20 patients were left with no residual tumor.7 were with≤2 cm and 5 were with＞2 cm residual tumor.Postoperative complications developed in 8 patients(25%),including subphrenic abscess,wound infection,gastric perforation,gastrorrhagia,phlebothrombosis,and bowel obstruction.The median follow up was 38 months,estimated 2-year and 5-year overall survival were 70%and 36%.Univariate analysis revealed that histological grade,residual tumor and courses of chemotherapy were influencing factors of the survival(P＜0.05),but multivariate analysis indicated that only residual tumor and courses of chemotherapy independently influenced survival(P＜0.05).Conclusions In epithelial ovarian cancer patients with splenic metastasis,low grade serous adenocarcinoma is most common.Splenectomy as part of cytoreductive surgery is associated with modest morbidity and mortality.Residual tumor and courses of chemotherapy are independent factors associated with the prognosis of the patients.

Objective To discuss the clinicopathologic characteristics and risk factors for lung metastasis of early-stage cervical cancer after radical hysterectomy. Methods The complete clinicopathologic data of patients with lung metastasis of cervical cancer after radical surgery from January 2008 to December 2013 admitted in Zhejiang Cancer Hospital were retrospectively analyzed by univariate and multivariate analysis. Results (1)There were 38 cases of early cervical cancer suffered from lung metastasis after radical hysterectomy during the period. The median age at diagnosis of cervical cancer was 46 years, the average lung metastasis time was 13 months after operation, 50.0%(19/38) cases occurred in the first year. Thirty-one cases were squamous cell carcinoma and 7 cases were non-squamous cell carcinoma.(2)Univariate analysis showed that age,clinical stage, manner of tumor growth, tumor grade, perineuronal invasion, para-aortic lymph node metastasis were not significant effect on postoperative lung metastasis(all P>0.05). But tumor size, histologic types, depth of stromal invasion, uterine body infiltration, lympho-vascular space invasion,pelvic lymph node metastasis, positive margin and abnormal tumor markers were significantly correlated with postoperative lung metastasis(all P<0.05). Multivariate analysis showed that only tumor size, histologic types and pelvic lymph node metastasis were independent risk factors for lung metastasis of cervical cancer(P<0.05). Conclusions Patients of early-stage cervical cancer with lung metastasis mostly occurs within 1 year after radical hysterectomy. Local large tumor lesions (tumor size>4 cm), non-squamous cell carcinoma and pelvic lymph node metastasis were more likely to have lung metastasis.

Objective To investigate the effect of early nursing intervention on severe complication of radical cystectomy and orthotopic ileal neobladder.Methods A total of 30 patients undergoing radical cystectomy with orthotopic ileal neobladder were randomly divided into the intervention group and the control group with 15 cases in each group,the control group received routine nursing,while the intervention group received psychological counseling,health education,sufficient preoperative preparation,postoperative strict tube care,nutritional support according to the serious complications after operation.The postoperative complications,indwelling time of tubes,hospitalization days between two groups were compared.Results Serious complications rate after surgery of the intervention group was lower than that in the control group.The indwelling time of tubes,length of stay in the intervention group were less than those of the control group,the two groups had significant difference.Conclusions Early predictive nursing intervention can reduce compli-cations rate after radical cystectomy and ileal neobladder,shorten the hospitalization time and improve the success rate of operation.

BACKGROUND:Buprenorphine transdermal patches have the characteristics of stable blood concentration, long duration of analgesia, respiratory depression and less side effects, which have been widely used in the treatment of moderate to severe chronic pain. OBJECTIVE:To observe the clinical outcome of preoperative analgesia by buprenorphine transdermal patches for pain management after posterior lumbar surgery. METHODS: Eighty patients scheduled for posterior lumbar decompression and interbody fusion under general anesthesia were enroled, 45 males and 35 females, aged 42-71 years, who were randomly divided into two groups, 40 cases in each group: experimental group and control group. In the experimental group, buprenorphine transdermal patches were given 2 days prior to the internal fixation, and intravenous injection of parecoxib was given for postoperative pain management. In the control group, placebo patches were given prior to the internal fixation, and self-control vein analgesia pump and intravenous injection of parecoxib were given for postoperative pain management. Visual analog scale scores were recorded at 6, 12, 24, 48 hours after surgery as wel as doses of tramadol hydrochloride and pethidine hydrochloride used postoperatively and side effects. The patient's satisfaction, drainage and blood count, erythrocyte sedimentation rate, C-reactive protein level at 48 hours postoperatively were detected and recorded in the two groups. RESULTS AND CONCLUSION:There was no significant difference between these two groups in visual analog scale scores, dosage of tramadol hydrochloride and pethidine hydrochloride used postoperatively, postoperative drainage amount, leukocyte count, erythrocyte sedimentation rate and C-reactive protein level (P > 0.05). Postoperative incidence of nausea, vomiting and delirium was lower in the experimental group than the control group (P < 0.05), but the patient's satisfaction in the experimental group was better than that in the control group (P< 0.05). These findings indicate that buprenorphine transdermal patches have better preemptive analgesia for posterior lumbar surgery, with less adverse effects and better patient's satisfaction.

Objective To observe the clinical efficacy of chemohyperthermia in the treatment of ovarian cancer com-bined with peritoneal effusion. Methods Forty patients with ovarian cancer combined with peritoneal effusion treated in our hospital from January 2006 to January 2013 were selected as the study subjects and randomly divided into the study group and the control group according to the random number method, with 20 patients in each group. All the pa-tients once went through surgical treatment, were diagnosed with epithelial ovarian cancer, received postoperative chemotherapy, had uncontrolled or recurrent tumor, and were complicated by peritoneal effusion. The control group was given conventional whole body chemotherapy and the study group was given intraperitoneal chemohyperthermia com-bined with whole body chemotherapy. The clinical efficacy of the two groups was observed. Results The study group had significantly higher treatment effective rate and life quality score than the control group (P<0.05), with statistical significance. Neither group had severe toxic nor side reactions; The existing toxic and side reactions were mild and re-mitted after symptomatic treatment. The 1-year survival rate of the study group was 85.0%and that of the control group was 65.0%. The study group had significantly higher 1-year survival rate than the control group(P<0.05), with statistical significance. Conclusion It is feasible to provide chemohyperthermia to the patients with ovarian cancer combined with peritoneal effusion and it can effectively improve the clinical efficacy and life quality, which is worthy of clinical appli-cation.

Objective: To explore the clinical effect of minimally invasive treatment of C type pilon fracture with single main plate combined with multiple planar screws for supporting fixation. Methods: From January 2013 to March 2017, data of 22 patients treated by minimally invasive treatment with single main plate combined with multiple planar screws for supporting fixa-tion were retrospectively analyzed. There were 17 males and 5 females, aged from 23 to 69 years (average, 51.2 years). All cases were closed fractures involving fibula including weight hitting (5 cases), traffic accident (7 cases) and fall injury (10 cases). There were 3 cases of 43-C1 type, 11 cases of 43-C2 type and 8 cases of 43-C3 type according to AO/OTA classification. According to the Rüedi-Allgöwer classification, there were 5 cases of type Ⅱ and 17 cases of type Ⅲ. Complications were recorded postopera-tively and the articular surface reduction was evaluated using the Burwell-Charnley score. At the last follow-up, Tornetta’s pilon fracture clinical treatment outcome criteria was used to evaluate ankle joint function. Results: All the patients were followed up for 13 to 25 months (average, 17.3 months). There were 20 cases of anatomical reduction, 1 case of fair reduction and 1 case of poor reduction according to the Burwell-Charnley score. All the 22 patients were healed with healing time of 3 to 6 months (aver-age, 4.8 months). The efficacy was evaluated according to the evaluation criteria of the clinical treatment results of pilon fracture by Tornetta: excellent in 8 cases, good in 10 cases, fair in 3 cases, and poor in 1 case. The excellent and good rate was 81.8% (18/22) . All patients had no complications such as wound edge blistering, skin necrosis and infection. Among them, 1 case of internal fixa-tion rejection occurred, and the incision was well healed after removal of the internal fixation after 3 months. Conclusion Mini-mally invasive treatment of C type pilon fracture with single main plate combined with multiple planar screws for supporting fixa-tion not only provides a better anatomical reduction of the articular surface, but also effectively reduces or even avoids incision complications. The long-term clinical results are satisfactory.

Objective: To evaluate the efficacy of articular compression molding techniques in the surgery for acetabular posterior wall fracture. Methods: A retrospective study was conducted of the 28 patients (28 hips) with fracture of acetabular posterior wall plus comminuted compression of articular surface who had been treated using the articular compression molding techniques at Department of Orthopedics, The Hospital of 81 Group Army of PLA from January 2014 to January 2018. They were 25 males and 3 females, aged from 26 to 63 years (average, 49.3 years). The time from injury to surgery ranged from 4 to 12 days (average, 7.8 days). According to the Letournel-Judet classification, all were single element (simple) posterior wall fractures combined with posterior dislocation of the femoral head and articular compression of different degrees; transient sciatic nerve injury was complicated in 12 cases. The posterior hip dislocations were timely and successful reset at emergency treatment. The compression fractures of the posterior wall and hip joint were treated by open reduction and internal fixation via the acetabular posterior (K-L) approach. The articular compression was treated by 4 stabilization techniques: absorbable screwing and blocking technique in 10 cases, indwelling screwing in 12 cases, indwelling Kirschner wiring in 2 cases and die push and squeeze tamping in 4 cases. The operation time, intraoperative bleeding and complications were recorded. The therapeutic efficacy was evaluated by the modified Merle d’Aubigne & Postel scoring criteria at the final follow-up. Results: The operation time lasted from 76 to 118 minutes (average, 94.2 minutes); the intraoperative bleeding ranged from 100 to 320 mL (average,220.8 mL). No incision liquefaction, infection or other complications occurred. The 28 patients were followed up for 10 to 36 months (average, 17.6 months). According to the Matta scoring criteria, 24 cases achieved anatomical reduction but 4 dissatisfactory reduction. By the modified Merle d’Aubigne & Postel scoring criteria at the final follow-up, the efficacy was evaluated as excellent in 26 cases and as good in 2. Heterotopic ossification was observed in 3 cases and microscopic free dense shadow in the joint cavity (about 2 mm in the round ligament) in 3 cases. There were no cases of obvious traumatic arthritis or osteoarthritis, femoral head necrosis, walking pain, lameness or hip abduction weakness. The 12 patients complicated with preoperative transient sciatic nerve injury recovered within 3 months after surgery. Conclusion The articular compression molding techniques can effectively treat severely comminuted articular compression in the acetabular posterior wall fracture and improve reduction of articular surface and hip joint matching, leading to stability and good joint function.

Objective:To study the signaling pathway of the up-regulation of claudin-5 expression by Xuebijing injection.Methods:Animal and cell models of acute respiratory distress syndrome (ARDS) were induced by lipopolysaccharide (LPS). ① In vivo study, 20 male Sprague-Dawley (SD) rats were randomly divided into 4 groups: control group, LPS group (LPS injection 10 mg/kg for 12 hours), Xuebijing control group (Xuebijing injection 1 mg/kg, twice a day, for 3 days), and Xuebijing intervention group (LPS injection after pretreatment of Xuebijing injection), according to random number method with 5 rats in each group. The lung tissues were taken to detect lung dry/wet weight ratio (W/D) and the morphological changes in each group. Claudin-5, phosphorylated forkhead box transcription factor O1 (p-FOXO1), total FOXO1 (t-FOXO1), phosphorylated Akt (p-Akt) and total Akt (t-Akt) in lung tissues were detected by immunohistochemical staining (IHC) and Western blotting. ② In vitro study, human pulmonary microvascular endothelial cells (HPMECs) were divided into 6 groups (5 holes in each group): control group, Xubijing control group (incubated with 2 g/L Xubijing for 24 hours), phosphoinositide 3-kinases (PI3K) signaling pathway LY294002 control group (incubated with 10 μmol/L LY294002 for 1 hour), LPS group (incubated with 1 mg/L LPS for 12 hours), Xubijing intervention group (incubated with 2 g/L Xuebijing for 24 hours, then with 1 mg/L LPS for 12 hours) and LY294002 intervention group (incubated with 10 μmol/L LY294002 for 1 hour, then with 2 g/L and Xubijing for 24 hours, and then with 1 mg/L LPS for 12 hours). The expression levels of claudin-5, p-FOXO1, t-FOXO1, p-Akt and t-Akt of HPMECs in each group were assessed by Western blotting. Results:In vivo study: ① Compared with the control group, the lung W/D ratio increased significantly in LPS group (6.79±0.42 vs. 4.19±0.13), and decreased significantly after the intervention of Xuebijing (4.92±0.38 vs. 6.79±0.42, P < 0.01). ② Morphological changes of lung tissue: compared with the control group, the injury of lung tissue in LPS group was more serious, which was significantly improved after Xuebijing intervention. ③ Expression levels of claudin-5, p-Akt/t-Akt and p-FOXO1/t-FOXO1: the expression levels of claudin-5, p-Akt/t-Akt and p-FOXO1/t-FOXO1 in LPS group were significantly decreased as compared with the control group (claudin-5/GAPDH: 0.33±0.03 vs. 1.03±0.07, p-Akt/t-Akt: 0.18±0.02 vs. 1.01±0.13, p-FOXO1/t-FOXO1: 0.16±0.06 vs. 1.00±0.19, all P < 0.01). After the intervention of Xuebijing, the expression levels were significantly increased as compared with the LPS group (claudin-5/GAPDH: 0.53±0.05 vs. 0.33±0.03, p-Akt/t-Akt: 0.56±0.12 vs. 0.18±0.02, p-FOXO1/t-FOXO1: 0.68±0.10 vs. 0.16±0.06, all P < 0.01). In vitro study: compared with the control group, the expression level of claudin-5 in the LPS group was significantly decreased (claudin-5/β-actin: 0.45±0.03 vs. 1.01±0.15, P < 0.01), and the expression level of claudin-5 in Xuebijing intervention group was also significantly decreased (claudin-5/β-actin: 0.80±0.08 vs. 1.01±0.15, P < 0.01). After the intervention of LY294002, the expression of claudin-5 was significantly decreased as compared with the Xubijing intervention group (claudin-5/β-actin: 0.41±0.02 vs. 0.80±0.08, P < 0.01). Conclusion:Xuebijing injection improve pulmonary vascular barrier function in rats with ARDS by up-regulating claudin-5 expression through PI3K/Akt/FOXO1 signaling pathway.
