Objective To observe the image features of high myopia with retinoschisis by spectraldomain optical coherence tomography (SD-OCT). Methods The clinical data of eight patients (eight eyes)of high myopia with retinoschisis were retrospective analyzed. All patients were diagnosed by SD-OCT (Topcon 3D OCT-1000), had no macular holes and underwent vitrectomy including internal limiting membrane (ILM) peeling and gas tamponade. All patients also underwent visual acuity, refraction,pre-mirror fundus examination and A/B-mode ultrasound examination. Visual acuity and SD-OCT were followed up at one, three and six months after surgery. Before surgery, pre-mirror fundus examination revealed shallow foveal detachment in 3/8 eyes, posterior scleral staphyloma in 7/8 eyes. SD-OCT showed concave arc stripes in 7/8 eyes, and outer retinoschisis in 8/8 eyes, middle or inner retinoschisis in 5/8 eyes and foveal detachment in 5/8 eyes. Results Six months after surgery, posterior retinoschisis disappeared in six eyes, foveal detachment still presented in one eye and parafoveal hole occurred in one eye. The corrected visual acuity improved from the 0. 15 to 0. 8 in one eye which had a restored continuous inner segment/outer segmen (IS/OS) line by SD-OCT. The corxected visual acuity improved from 0. 01 to 0. 1 in one eye, from 0. 05 to 0. 15 in one eye, not changed in five eyes. There was no continuous IS/OS line in those patients by SD-OCT. Conclusions SD-OCT shows a variety of morphological features of myopic retinoschisis which could be cured anatomically and functionally by vitrectomy combined ILM peeling. The continuity of IS/OS layer from SD-OCT could help to interpret the vision recovery after the operation.

Objective To investigate the risk factors related with postoperative complications following radical gnstrectomy for gastric cancer in cirrhotic patients. Methods In this study, 1474 cases underwent radical gastrectomy for gastric carcinoma in the past six years and the postoperative complications were retrospectively reviewed. The risk factors related with postoperative complications of cirrhotic patients were analyzed by Logistic regressive analysis. Results The postoperative morbidity rates of the 2 groups with or without liver cirrhosis were 51.22% and 23.94% (X2 = 15.955, P<0.01), and the mortality rate was 7.32% and 0.91% (P = 0.009), respectively. The main complications of the group with liver cirrhosis were postoperative aseites (5 cases), hepatic failure (4 cases), wound infection or dehiscence (4 cases), intra-abdominal infection (4 cases), etc, and three patients in the group died from extensive bleeding, jejunal fistula and hepatic failure respectively. Univariate Logistic analysis revealed that age (OR = 1.277, 95% CI:0.991 ～ 1.646), preoperative nscites (OR = 20.900,95% CI: 2.349 - 185.933), the albumin level (OR =0.160,95% CI:0.041 ～ 0.629), Child classification (OR = 9.500,95% CI: 1.046 ～ 86.261), portal hypertension (OR = 4.000,95% CI: 1.057 ～ 15.138), esophageal variees (OR = 4.400,95% CI: 1.095 ～ 17.676), transfusion (OR =3.714,95% CI: 1.021 ～ 13.511) and blood loss (OR = 1.442, 95% CI:1.023 ～ 2.034) were the main factors associated with postoperative complications of the group with liver cirrhosis. Muhivariable Logistic analysis showed that preoperative ascites (OR = 19.213,95% CI: 1.569 ～ 231.255), Child classification (OR = 12.661,95% CI: 0.721 ～ 222.458), esophageal varices (OR =6.008,95% CI:0.857 ～42.097) and blood loss (OR = 1.574,95% (7,1:0.938 ～ 2.640) were the independent risk factors. Conclusion Gastrectomy for gastric carcinoma in cirrhotic patients engenders considerably high postoperative mortality and morbidity. Preoperative ascites, Child classifation, esophageal variees and intraoperative blood loss were factors closely related with postoperative complications.

The urothelium is a transitional epithelium which lines on the renal pelvis, ureter, bladder and proximal urethra adjacent to the bladder. It’s a permeability barrier. In the process of urothelial development or injury repair, the mature urothelial cells expressing uroplakin appears after the hierarchical transcription of a series of transcription factors in basal stem cells. Understanding normal urothelial differentiation process of the urothelial cells could be beneficial to uncover the development of urothelial carcinoma so that to provide targeted therapy options and the study of the urinary tract repair process after injury. In addition, the study of stem cell differentiation microenvironment also provides important theoretical support for tissue engineering and tissue reconstruction. In this review, we discuss the latest findings on urothelial cell differentiation and its clinical significance.

Objective To investigate the clinical efficacy of heat-sensitive point moxibustion in treating functional dyspepsia. Methods Fifty-six patients with functional dyspepsia were randomly allocated to treatment and control groups, 28 cases each. The treatment group received heat-sensitive point moxibustion and the control group took domperidone tablets. The symptoms were scored and plasma motilin was measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 89.3% in the treatment group and 82.1% in the control group; there was a statistically significant difference between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the symptom score and plasma motilin in the two groups (P<0.05). There were statistically significant post-treatment differences in the symptom score and plasma motilin between the treatment and control groups (P<0.05).Conclusion Heat-sensitive point moxibustion is an effective way to treat functional dyspepsia.

Objective To investigate the reaction of the limbs treated with different concentration of Trichostatin A(75?mol/L,750 ?mol/L,1.5mmol/L),a histone deacetylase(HDAC)-inhibitor.This may be useful to improve our understanding of the role of chromatin remodelling and epigenetic control of gene expression patterns and ultimately the development of drugs against cancer. Methods Using the chicken embryonic limb as an experimental model.The embryos received grafts of TSA soaked beads or PBS control beads into the right forelimb buds.Then they were submitted to in situ hybridization with probes and apoptosis test.Results TSA could modulate the expression of some myogenesis related genes,MyoD and Myf5 during chicken myogenesis.Using apoptosis staining methods,there was no significant apoptosis in the TSA(75?mol/L) treated embryos.However the induction of morphological changes and apoptosis at specific stage was possible with high concentration of TSA.Conclusion TSA(75?mol/L) regulates certain important transcriptional targets and strongly control muscle differentiation.Increasing the concentration of TSA(≥750?mol/L) can induce apoptosis and embryonic limb malformations.Chicken limb development can serve as a convenient in vivo model for studying the effect of HDAC inhibitors.
