AIM: To evaluate the efficacy and safety of vitrectomy combined with internal limiting membrane ( ILM) peeling for treating foveoschisis in high myopia.
METHODS:Thirty high-myopia patients (30 eyes) with foveoschisis from March 2011 to March 2013 were divided two groups: the treatment group ( 16 eyes ) was treated with vitrectomy combined with ILM peeling, and the control group (14 eyes) was treated only with vitrectomy. The foveoschisis reattachment and and best spectacle-correction were measured preoperatively and 2mo after surgery.
RESULTS: The improvement of foveoschisis reattachment and best spectacle - correction in the treatment group was significantly better than those in the control group (P<0. 05).
CONCLUSION: Vitrectomy combined with ILM peeling is a safe and effective treatment for foveoschisis in high myopia.

Objective　To evaluate the safety and primary outcomes of transumbilical laparoendoscopic single-site radical nephrectomy (LESS-RN) by using home-made single-port device.　Methods From July 2010 to November 2011,we had performed transumbilical LESS-RN on eleven renal cell carcinoma patients by using the home-made single-port device.There were 5 males and 6 females in this group.The mean age was 49 (37 -68) years and mean body mass index was 24.2 (18.4 -30.4) kg/m2.Ultrasound and CT scan revealed 11 renal tumors (7 on left and 4 on right),with 3 on the upper pole,4 in the middle and 4 in the lower pole.There were 2 cases with suspicious lymph node metastasis and one case with renal cyst.There was no distant metastasis.The intracorporal procedure was similar to conventional laparoscopic radical nephrectomy.　Results　Except two cases converted to conventional laparoscopic RN and one case converted to hand-assisted laparoscopic RN,the other procedures were completed successfully without open conversion.The mean operative time was 225 min (155 -297 min) and mean estimated blood loss was 271 ml (50 -900 ml).Postoperative results showed that all cases were renal cell carcinoma and there were 3 cases in T1a,5 cases in T1b and 3 cases in T2a.The mean visual analog pain scale (VAPS) was 4 (3 -6),and mean hospital stay was 10 d (5 -15 d).With the mean follow-up of 17 months (8 -24 months),all patients were alive with no evidence of local recurrence or metastasis.Patients were satisfied with the cosmetic results of the wound recovery.　Conclusions　Transumbilical LESS-RN using home-made single-port device is a safe approach in selected patients and has excellent cosmetic results. Primary oncologic outcomes are good.However,we will still need large clinic trials to further evaluate the efficacy and safety of LESSRN.

Objective:To describe a feasible surgical technique for patients with renal cell carcinoma associated with a supradiaphragmatic tumor thrombus that avoids cardiopulmonary bypass procedure. Methods:We retrospectively analyzed 2 cases with right kidney tumor and tumor thrombus above the dia-phragm treated in April and August,2015.The two patients were both female,aged 73 and 67 years. The tumor sizes of right kidneys were 7.0 cm ×6.3 cm ×5.7 cm and 8.7 cm ×7.0 cm ×5.2 cm,and the tumor thrombuses were 1.3 cm and 1.8 cm above the diaphragm.The second patient had synchro-nous metastasis in right adrenal gland ,and the tumor thrombus arose from the adrenal vein but not the renal vein.Intraoperative transesophageal echocardiography (TEE)was used to assess real-time mobility of the thrombus.A modified chevron incision was used,the right kidney was mobilized laterally and pos-teriorly,and the renal artery was identified,ligated,and divided.The infradiaphragmatic inferior vena cava (IVC)was exposed and isolated by mobilizing the liver off the diaphragm or to the left (piggyback liver mobilization,case 2).The central diaphragm tendon was dissected or incised in the midline until the supradiaphragmatic intrapericardial IVC was identified and gently pulled beneath the diaphragm and into the abdomen.The tumor thrombus was then “milked”downward out of the intrapericardial IVC un-der the guidance of TEE.The distal and proximal IVC to the tumor thrombus,porta hepatis,and left re-nal vein were clamped.Tumor thrombus was removed from the IVC.The IVC was sutured and vascular clamps were placed below the major hepatic veins.Pringle’s maneuver was then released and hepatic blood drainage was permitted during closure of the remaining IVC.Related literature was reviewed.Re-sults:Complete resection was successful through the transabdominal approach without CBP in both pa-tients.Estimated blood loss was 1 500 mL and 2 000 mL,and 1 200 mL and 800 mL of blood were trans-fused.The postoperative courses were uneventful.Both patients subsequently underwent tyrosine-kinase inhibitor therapy.Both patients were alive without tumor recurrence or new metastasis during the follow-up of 6 months and 9 months.Conclusion:In selected cases,renal cell carcinoma extending into the IVC above the diaphragm can be resected without sternotomy,CBP or DHCA.

Objective To evaluate the recovery rate of erectile function (EF) and identify various factors predicting the recovery of EF in men undergoing laparoscopic radical prostatectomy (LRP) in our center.Methods From January 2011 to December 2012,a total of 106 men with localized prostate cancer underwent LRP in our center by one surgeon were included,and we gathered the preoperative EF condition and perioperative factors,such as patients' age,comorbidity and surgical procedure,et al.We followed up all the patients by telephone in August 2013 to collect the EF recovery data of these paticnts after LRP,with the mean follow-up of 18 (8-31) months.We analyzed the perioperative factors in order to predict the EF recovery after LRP.Results A total of 60 patients with preoperative sexual activity were included,and there was no difference in baseline data compared with other cases.Recovery of potency was defined as postoperative penile erection.The recovery rate of EF was 46.7％ (28/60) without the use of any drugs or devices for erection assistance.In our study,the recovery rate of EF in age ≤60 years was 90.0％ (9/10),and it was better than other two older groups (P =0.001).In patients whose preoperative IIEF-5 score was 22-25,the recovery rate of EF was 66.7％ (8/12),and it was better than those with IIEF-5＜22 (P=0.006).The recovery rate of EF in patients with preserved neurovascular bundle was 53.1％ (26/49) and it was 83.3％ (5/6) in patients with preserved accessory pudendal artery,which was better than those without preservation (P=0.036 and P =0.023).Conclusions In our study,age and preoperative EF were the significant factors to predict potency recovery,and preservation of neurovascular bundle and accessory pudendal artery during LRP were the positive predictor factors.

Objective:To study the HLA-DPB1 allele polymorphism in Ewenki from Inner Mongolian.Methods:HLA-DPB1 allele polymorphism in normal Ewenki were determined by PCR with sequencing-based-typing(SBT).Results:20 HLA-DPB1 alleles were observed and compared with other ethnic groups,the allele frequency of HLA-DPB1*02012(24.4%) and DPB1*0402(22.6%),DPB1*0401(20.2%),DPB1*0501(10.7%) are highest,while others are lower.Conclusion:The distributions of HLA-DPB1 alleles frequencies in normal Ewenki from Inner Mongolia has a unique style.It is most important to further study anthropology and related to illness in Ewenki nationality.

Objective: In order to investigate the effect of Shufeng Jiedu Capsule (SJC) compatibility on anti-inflammation of pneumonia model rats. SJC whole prescription and its components with effect of heat-clearing and toxin-removing and exterior-releasing were studied. Methods: The pneumonia model of rats induced by Streptococcus pneumoniae was used, divided into control group, model group, cephalexin group, SJC whole prescription group (whole prescription group), SJC exterior-releasing group (exterior-releasing group), and SJC heat-clearing and toxin-removing group (heat clearing and detoxifying group). After administration for 6 d, the colony count of peripheral blood and alveolar lavage fluid (BALF), the number of white blood cell (WBC) and its classification in peripheral blood and alveolar lavage fluid, the contents of nuclear transcription factor-kappa B (NF-κB) and cyclooxygenase (COX-1 and COX-2) were tested to evaluate the compatibility rationality. Results: Compared with model group, the whole prescription group, exterior-releasing group, and heat-clearing and toxin-removing group significantly reduced the colony count of peripheral blood and alveolar lavage fluid, significantly reduced the number of WBC in peripheral blood, significantly increased the proportion of eosinophils and reduced the proportion of basophils. The Q values of rats in the whole prescription group were beyond 1 on two indicators, which were the number of WBC and the proportion of eosinophils. The number of WBC in alveolar lavage fluid and the contents of NF-κB and COX-2 decreased significantly in the whole prescription group, exterior-releasing group and heat-clearing and toxin-removing group. Conclusion: SJC has significant anti-inflammatory effect and therapeutic effect on Streptococcus pneumoniae infection in rats. The exterior-relieving component and the heat-clearing and toxin-removing component have significant synergistic effects.

Aim To investigate the effects of tamoxifen on the proliferation and DNA synthesis of cultured human pituitary adenoma cells and make a further investigation of the mechanism of the inhibitory effect of tamoxifen on the proliferation of pituitary adenoma cells. Methods The techniques of MTT colorimetry, 3H-TdR, flow cytometry, PKC activity detection and cAMP/ cGMP levels detection were used to detect or observe the effects of tamoxifen on proliferation, DNA synthesis, cell cycle, PKC activity and cAMP/ cGMP levels of cultured human pituitary adenoma cells, respectively.Results ①Tamoxifen (0.1,1 and 10 ?mol?L -1) inhibited the proliferation and DNA synthesis of cultured human pituitary adenoma cells in a dose-dependent manner.② tamoxifen (1,10 and 20 ?mol?L -1) increased the ratio of G_1 phase of pituitary adenoma cells, and decreased the ratio of S and G_2 phase markedly;②compared with control, PMA, a PKC activator, increased the activity of membrane and total PKC in human pituitary adenoma cells. However, after a 15-min treatment with tamoxifen (10 ?mol?L -1),a significant reduction of the activity of cytoplasm, membrane and total PKC in human pituitary adenoma cells was observed;③tamoxifen (1 and 10 ?mol?L -1) increased the amount of cAMP in the cytoplasm of human pituitary adenoma cells, but had no effect on that of cGMP. Conclusion These data provide an important clue to explore the molecular mechanisms of the inhibitory effect of tamoxifen on the proliferation of pituitary adenoma cells, and suggest that the modulating effect of tamoxifen on the proliferation of pituitary adenoma cells results from interactions of several cellular signaling pathways.
