Background Excimer laser corneal refractive surgery is widely used because it reduces the dependency of refractive error eye to glasses.However,the adverse effects of anti-inflammatory drugs is a problem after operation.Lotemax eyedrops is a kind of steroidal anti-inflammatory drug,with a good effect on the operative eye.But its influence on intraocular pressure(IOP) after long-term topical administration is less studied.Objective This study was to investigate the influence of lotemax eyedrops on IOP after long-term topical administration in myopic eyes received excimer laser corneal refractive surgery.Methods An one-month retrospective case serial study was adopted.The case history data of 1552 eyes from 1552 Patients who received excimer laser corneal refractive surgery were collected in Tangshan Eye Hospital from 2011 January to 2012 January,including 321 eyes with laser in situ keratomileusis(LASIK),608 eyes with sub-Bowman keratomileusis (SBK) and 623 eyes with femtosecond laser for flap excimer laser in situ keratomileusis(FS-LASIK).Lotemax eyedrops was topically administered after operation 4 times per day initial and then decreased 1 time weekly for 1 month.IOP was measured in before,1 week,2 weeks,3 weeks,4 weeks after operation with non-contact tonometer.The increasing range of IOP was divided into ＜5 mmHg,5-15 mmHg and ＞ 15 mmHg after operation.Optical head parameters were measured by Heidelberg retina tomography when IOP increasing after operation.Results Within 1 month,elevated IOP was found in 47 of 1552 eyes after administration of lotemax eyedrops,including 3.12％ (10/321) in the LASIK group,3.29％ (20/608) in the SBK group and 2.73％ (17/623) in the FS-LASIK group,without significant difference among them(x2 =1.95,P＞0.05).The IOP elevated 1 week after operation and remained normal after that till drug withdrawal in all eyes.There were no significant differences in the disk area (1.65 ±0.44) mm2 vs.(1.66 ±0.44) mm2,disk volume (0.40 ±0.09)mm3 vs.(0.39±0.08) mm3 and mean nerve fiber layer thickness (0.28 ± 0.08) mm vs.(0.29 ± 0.07) mm in IOP elevation duration compared with 1 month after IOP recovery(t =0.34,0.81,0.48,P＞0.05).Conclusions Topical administration of 0.5％ lotemax eyedrops after excimer laser corneal refractive surgery leads to reversible high IOP.It is very important to monitor the IOP during use of the drug.

Objective To study the prevalence of thrombocytosis in patients with non-small-cell lung cancer (NSCLC) and its correlation with clinicopathological features.Methods 156 patients with advanced NSCLC were retrospectively analyzed.The platelets degree between the groups with different sex,age,smoking,histological type of advanced NSCLC was compared and analyzed statistically.The relationship between the platelet count and chemotherapy effects was analyzed.Single analysis and Cox regression analysis were used for TTP and OS.Results Compared with the healthy persons,Plt significantly elevated in group with advanced NSCLC (36.5 ％,57/156 vs 5.0 ％,5/100) (P ＜ 0.01),and thrombocytosis group responded poorly to chemotherapy (22.8 ％,13/57 vs 39.4 ％,39/99) (P ＜ 0.05).The TTP (3.0 months vs 5.2 months) and OS (11.2 months vs 14.2 months) of Plt elevated group were significantly shorter than those of normal group.Conclusion Thrombocytosis is closely related to progress and metastasis of advanced NSCLC.Platelet count can be used as an assistant index in the prognosis judgment of patients with advanced NSCLC.

AIM:Nitroxyl ( HNO) increases myofilament Ca 2+responsiveness relative to increases in intracel-lular Ca2+in cardiac muscle.In this study, we further investigated this effect of HNO on trabecular muscles from phospho-lamban knockout ( PLB-KO) and wide-type ( WT ) mice using a novel HNO donor , 1-nitrosocyclohexyl acetate ( NCA ) . METHODS:Trabecular muscles were dissected from the right ventricles of the rat hearts and mounted between a force transducer and a motor arm.The muscles were superfused with K-H solution (pH 7.4) at room temperature.Fura-2 was loaded into the trabecular muscles via electrophoresis .The length of the sarcomere was set to 2.2~2.3μm.During stead-y-state activations, the maximal Ca2+-activated force and Ca2+required for 50% activation were measured.RESULTS:The intracellular Ca 2+transients and force of the PLB-KO muscles at baseline were higher than those of the WT muscles and exhibited a negative force-frequency relationship (FFR).NCA (2.5μmol/L) increased systolic force in both PLB-KO group and WT group at any given [Ca2+]o.However, there was more dramatic increase in the force development due to moderate increases in the intracellular Ca 2+transients in the WT muscles when external Ca 2+increased from 1.5 to 4.5 mmol/L under NCA.NCA did not affect the negative FFR in PLB-KO muscle.Steady-state force-Ca2+relations obtained from skinned muscles were not different between the 2 groups, while NCA increased Ca2+responsiveness in skinned mus-cles from both PLB-KO and WT mice.CONCLUSION:HNO increases force development in both PLB-KO and WT mus-cles as a result of increases in myofilament Ca 2+responsiveness .The increased intracellular Ca 2+transients are accompa-nied by greater force development in WT mice , suggesting that HNO improves Ca 2+activation and establishes HNO as a positive inotropic agent with novel mechanisms .

Stereotactic radiotherapy (SRT), also known as stereotactic ablative radiotherapy (SABR), includes stereotactic radiosurgery and stereotactic body radiotherapy (SBRT). This technique has the characteristics of large single fractional dose, few fractions, high equivalent biological doses, and rapid fall off-target doses. It can be implemented by relatively special equipment such as Gamma knife, Cyberknife, Tomotherapy and Vero 4D RT system, etc. In many cases, SBRT technique is employed based on linear accelerators. SRT differs from conventional radiotherapy in terms of the plan design and plan evaluation. Consequently, it is necessary to discuss the differences and provide guidance for clinical application and research.

ObjectiveTo observe the effects of acupuncture combined with massage on shoulder subluxation and motor function recovery of the upper extremities in patients with hemiplegia after stroke.Methods60 hemiplegic patients were randomly divided into two groups for treatment with acupuncture cooperates with massage or usual rehabilition, respectively. The recovery of the patient's shoulder subluxation and movement function of upper extremities were evaluated 2 months after treatment. ResultsThe shoulder subluxation and movement function of the upper extremities were improved after treatment with both therapies (P<0.01), and acupuncture cooperates with massage showed better effect (P<0.01). ConclusionAcupuncture cooperates with massage can facilitate the recovery of shoulder subluxation and motor function of the upper extremities after hemiplegia.

[Objective]The oxidative injury of retinal pigment epithelium(RPE)plays a key role in the pathogenesis of age-related macular degeneration(ARMD). This study is to investigate the effects of endoplasmic reticulum stress and the vital transcriptional factor X-box binding protein 1(XBP1)in acrolein-induced oxidative damage of RPE.[Methods]RPE cells were treated with acrolein (75μmol/L)for 2~24 h,expression of glucose regulated protein 78(GRP78)and XBP1 was determined by Western blot analysis. After being transfected with XBP1 siRNA with 24 h,the expression of XBP1 was knocked-down in RPE cells. Protein level of Nrf2 and SOD2 was then determined by Western blot analysis and intracellular Reactive Oxygen Species(ROS)generation was determined by DCF staining. Acrolein was added for 8 h after being transfected with XBP1 siRNA or control siRNA for 24 h. Apoptosis was detected by TUNEL assay before and after the treatment. Subretinal injection of Cre or GFP adenovirus was performed in XBP 1flox mice. After 1 week the mice were sacrificed. Total RNA was extracted from mice eyecups using TRIzol and real-time RT-PCR was performed to determine the two XBP1 down-stream genes,ERdj4 and p58IPK. Cryosectioning and immunofluorescent staining were performed to look at the expression of XBP1,Nrf2 and SOD2 in mice RPE.[Results]Protein level of GRP78 was significantly un-regulated after exposure to acrolein for 2 and 4 h. XBP1 was activated after acrolein treatment for 6 h. Knock-down of XBP1 by siRNA down-regu?lates anti-oxidant genes expression and increased ROS generation in RPE cells. Loss of XBP1 exacerbates acrolein-induced cell apoptosis. XBP1 was knocked-down in the RPE of XBP1flox mice after subretinal injection of Cre adenovirus. Decreased mRNA level of ERdj4 and p58IPK,and decreased Nrf2 and SOD2 expression were seen in the Cre-injected group.[Conclusions]Acrolein induces ER stress and activates XBP1 in RPE cells. Knock-down of XBP1 down-regulates anti-oxidant genes expression ,increases ROS generation,and exacerbates acrolein-induced cell apoptosis. XBP1 plays a role in the anti-oxidant defense in the RPE cells.

Objective To evaluate the clinical outcome of a method of renconstruction of Type Ⅱb defect of thumb both and reserving the length of the donor toe.Methods From March 2012 to Febrary 2014,there were 11 cases of thumb defect treated in our hospital.According to Gu Yudong's classification,all were type Ⅱ b.Three were open defect and others were closed defect.All were treated with combined transfer of big toe wrap-around flap and autogenous iliac graft for thumb reconstruction while a superficial circumflex iliac artery perforator flap was used to resurface the donor defect.The donor site of the belly was sutured directly.Results All of the reconstructed thumb survived.Among 11 flaps,arterial crisis occurrred in 1 case,venous crisis occurred in 2 cases,and all survived after operative treatment.The patients were followed-up from 3 mooths to 15 months,all the thumbs had a good appearance.The thumb opposition function was good and sensation recovery to S3 + and two-point discrimination from 6-8 mm.The donor big-toe was preserved.All the flaps had satisfactory color and texture,but looked a little plump.All the patients had no effect on walking and running.Four flaps had more beautiful appearance after flap plastic.There was only one linear scar on the belly donor without any discomfort.Conclusion It is an effective method of combined transfer of big toe wrap-around flap and autogenous iliac graft while a superficial circumflex iliac artery perforator flap was used to resurface the donor defect used to reconstrucution of Type Ⅱ b defect of thumb is very good.

Objectives To investigate the clinical characteristics and diagnosis of Gaucher disease. Methods The clini-cal features, enzyme activities and genetypes of an infant with Gaucher disease II were analyzed. Results The main clinical manifestations of the infant included hepatosplenomegaly, ocular dyscinesia and mental retardation. Gaucher′s cells could be seen in the bone marrow aspirates. Glucocerebrosidase activity was low (0.3 nmol/g/min). Serum chitotriosidase activity was high (87317 nmol/L/min). GBA mutations were M85T (c.371T>C) and R120W (c.475C>T). Conlusions Main features of Gau-cher disease II are hepatosplenomegaly with nerve system injury. Glucocerebrosidase activity and gene analysis are important for the diagnosis of Gaucher disease.

Objective To explore the metabolic characteristic of prostate cancer (PCa) in central gland with magnetic resonance (MR) spectroscopic, and evaluate the value of MRS in the differential diagnosis of benign prostatic hyperplasia nodus. Methods MR images were performed in 38 cases with prostate disease by 3.0T MR, 11 cases with PCa in central gland and 27 cases with benign prostatic hyperplasia nodus. All the cases were scanned by routine, then by the combined MRS. MRS findings were reviewed in 27 cases with benign prostatic hyperplasia (BPH) and 11 cases with PCa (3 in central gland origin, 8 with large tumor invading both peripheral zone and central gland). (Cho+Cr)/Cit ratios of PCa and BPH were retrospectively measured, (Cho+Cr)/Cit of PCa voxels were compared with that of BPH voxels. Results Significantly higher choline levels and lower citrate levels were observed in central gland of PCa compared with BPH. In the glandular BPH region, the amount of Cit was high; while in the stromal region, the Cit and Cho level was much lower. The average (Cho+Cre)/Cit values of PCa and BHP were 1.94±1.43 and 0. 83±0. 28 respectively, the difference in ratio between both was statistically significant (P＜0. 01). Conclusions The combined use of MRI and MR spectroscopy is propitious for differentiating prostate cancer in central gland and benign prostatic hyperplasia nodus and for increasing the diagnostic accuracy of prostate cancer.
