Objective To study clinical features, treatment and prognosis of nasal NK/T cell lymphoma associated Hemophagocytic Syndrome (HPS).Methods Retrospectively analysis method was used to analyze the clinical data of 3 patients with nasal NK/T cell lymphoma associated HPS. Results 3 patients with nasal NK/T cell lymphoma fulfilled the criteria of HPS. All patients had adverse prognostic factors of lymphoma.1 patient developed HPS as the main primary manifestations of underlying lymphoma,the other 2 patients developed HPS during lymphoma progression. In three cases, bone marrow was infiltrated with lymphoma cells.When HPS occurred,the disease progressed rapidly.The most obvious clinical features were fever,pancytopenia,hypofibrinogenemia,hyperferritinemia,and hemophagocytosis in bone marrow. After being treated according to the HLH-2004 combined with chemotherapy, all patients showed a clinical response,but with the progression of lymphoma,HPS quickly relapsed,and all patients died of severe hepatic dysfunction,coagulopathy,or DIC.Conclusion Nasal NK/T lymphoma associated HPS is an invariably fatal disease with poor prognosis,typically occurring at advanced stage or the terminal phase of the disease.HLH-2004 based protocol in combination with chemotherapy is helpful for nasal NK/T cell lymphoma associated HPS,which may delay disease progression and provid opportunities for the treatment of primary disease.

Objective To explore the influence of antidepression therapy on symptom score and quality of life in elderly benign prostatic hyperplasia with depression.Methods A total of 94 elderly patients with benign prostatic hyperplasia and depression were randomly divided into two groups:control group (regular drugs) and therapy group adding citalopram 20 mg,once daily for 3 months.The changes of internatio nal prostate sympeom score (IPSS) symptom score,hamilton depression (HAMD) and scores of short form (36) health survey before and after treatment were compared between the two group.Results After treatment,IPSS symptom score [(10.74 ± 4.72) vs.(16.42±8.09)] was much lower in therapy group than in control group (t=4.16,P＜0.05).Each dimension of quality of life was increased after antidepression treatment [physical function (67.75 ± 9.99) vs.(63.09±7.90),SF-36 role physical (70.90±10.85) vs.(62.81±9.16),bodily pain indices (72.75± 10.59) vs.(63.13 ± 9.47),general health (62.59 ± 9.38) vs.(53.67 ± 7.52),vitality (64.09±8.96) vs.(58.11 ± 7.87),social functioning (71.84 ± 6.87) vs.(64.99 ± 7.21),roleemotional (70.15±9.93) vs.(65.01±9.18),mental health (68.74±8.23) vs.(61.77±7.83),all P＜0.05].Conclusions More attention should be paid to antidepression therapy in the elderly with benign prostatic hyperplasia and depression.

Objective To investigate the relationship between the expression of eonnexin 43 (Cx43) and clinicopathologieal characteristics of gastric cancer, and to study the role of Cx43 in peritoneal metastasis of gastric cancer. Methods Thirty-two patients who had gastric cancer and with peritoneal metastasis had been admitted to Southwest Hospital from January 2000 to December 2008. Gastric cancer tissues, adjacent tissues and metastatic peritoneal tissues were obtained postoperatively, and the expression of Cx43 was detected by immunohistochemistry. The relationship between Cx43 expression and clinicopathological characteristics of gastric cancer was analyzed. All data were analyzed via Spearman rank correlation coefficient, Fisher exact probability and chi-square test. Results The expression of Cx43 was mainly detected in the cell membrane and cytoplasm. The positive expres-sion rates of Cx43 in gastric cancer tissues, adjacent tissues and metastatic peritoneal tissues were 34% (11/32), 100% (32/32) and 94% (30/32), respectively. There were significant differences in the Cx43 expression between gastric cancer tissues and adjacent tissues (X~2=28.350, P < 0.01), and between gastric cancer tissues and metastatic peritoneal tissues (X~2 = 21.989, P < 0.01). The expression of Cx43 did not correlate with age and sex of patients (r = -0.030, - 0.169, P > 0.05), but with tumor differentiation, histological type and lymph node metastasis (r = 0.750, 0.642, - 0.357, P < 0.05). Conclusions There is a decreased expression of Cx43 in gastric cancer tissues and a up-regulated expression of Cx43 in metastatic peritoneal tissues. Cx43 may play a positive role in the peritoneal metastasis.

Objective To observe the clinical effect of surface electrical stimulation on bladder spasm among patients with spinal cord injury,and compare it with that of therapy combining electrical stimulation with bladder function training.Methods Forty-two patients with bladder spasm after spinal cord injury were randomly divided into an experimental group (n=21) and a control group (n=21).Patients in the experimental group were further divided into three subgroups:patients with cervical spinal injury (n =7),thoracic spinal injury (n =9) and lumbar spinal injury (n =5).Both the experimental group and control group were given normal bladder function recovery exercise,while the experimental group was given the extra electrical stimulation on the surface of the sacral nerve.Urodynamic tests including the maximum detrusor pressure,bladder capacity,residual urine volume and bladder compliance were conducted for both groups before the treatment,after the first and the second 18-days of treatment and during a follow-up visit 2 months after the intervention.Results After the first course of treatment,significant differences were found in all measurements in the experimental group and most measurements of the control group except for the residual urine volume.Significant differences were found in all measurements after the second course of treatment compared to those after the first course in both groups.After the two courses of treatment and during the follow-up visit the average residual urine volume of the experiment group was significantly better than that of the control group.After the second course of treatment the average maximum detrusor pressure and bladder compliance of the experimental group were significantly better than those of the control group.Conclusion Surface electrical stimulation significantly improves the urodynamics and bladder function of patients with bladder spasm after spinal cord injury and its therapeutic effect is greater for patients with cervical and thoracic spinal injury than for those with lumber spinal injury.

Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

The bleeding again of the control group 7. 81% ( 5/64 ), higher than the treatment group was 5. 19% (7/135), the difference was statistically significant (P<0. 05).CONCLUSlON: Evidence-based treatment of traditional Chinese medicine for high myopia macular hemorrhage has good clinical effect, can shorten the treatment time, and is beneficial to the recovery of postoperative vision, worthy of clinical popularization and application.

?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

Objective To evaluate the role of early cleavage embryo in combination with embryo growth rate and morphology scoring in embryo selection in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods Six hundred and ten IVF/ICSI cycles were randomly assigned to group A(269 cycles) and group B(341 cycles). In group A, transferred embryos were chosen according to embryo growth rate and morphology scoring by 72 h(D3) after fertilization, while early cleavage embryo was added to the selecting system in group B. The pregnancy rate and implantation rate were compared between two groups, and the clinic outcomes were compared between transfers with early cleavage embryos and without early cleavage embryos in group B. Results The pregnancy rate and implantation rate in group B were significantly higher than those in group A (P < 0.05). Transfers with early cleavage embryos also achieved much higher pregnancy rate and implantation rate in group B (P < 0.01). Conclusion Compared with embryo growth rate and morphology scoring, early cleavage embryo in combination with embryo growth rate and morphology scoring can improve the clinical outcomes in IVF/ICSI cycles.

Cross-talk of intracellular signaling pathways that share common components (hubs) is organized in form of a bow-tie network topology.Signaling cross-talk is functionally pleiotropic for target genes regulation, resulting in functional redundancy, synergism and antagonism, which should be precisely controlled to prevent signaling 'leaking' or 'spillover'.Thus, the biological system has evolved multiple insulating mechanisms to achieve stimulus-specific response that maintains intracellular homeostasis.The insulation mechanism of signaling cross-talk suggests: (1) the functional duality of cross-talk molecules that determine cell fate requires selectively targeting dysregulated cross-talk molecules while protecting the normal ones from off-target or unintended effects, and we propose them as the targetable cross-talk molecules;(2) cross-talk molecules are usually carried on the macromolecular complex as their functional platforms, thus the structural plasticity of conformational changes at the interaction surface of cross-talk molecules asks for intensive work on the relationship study between drug binding and biological activity, which we propose as the accessible cross-talk molecules.Therefore, signaling cross-talk and its insulation mechanism play instructive leading roles in resolving the bottlenecks of current drug R&D and improve the clinical outcome.
