Objective To investigate the causes, diagnosis and treatment of gastrolienal portal hypertension. Methods During recent 10 years, 32 cases of gastrolienal portal hypertension were admitted. Clinicopathological features were analyzed. Results The main causes of this entity was chronic pancreatitis or pseudocyst of the pancreas (14 cases), tuberculosis of lymph nodes in retroperitoneum (7 cases) , retroperitoneal malignant lymphoma (3 cases) and pancreatic tumors (8 cases). Definite diagnosis was made in all 32 cases during the hospitalization. Twenty cases underwent surgery including splenectomy (11 cases) , splenectomy plus portal-azygous disconnection (5 cases) , splenectomy plus distal pancreatectomy (4 cases) , endoscopic varicose vein ligation combined with partial splenic embolization (2 cases), and endoscopic varicose vein ligation ( 5 cases). Conclusion A definite diagnosis of gastrolienal portal hypertension lies in the surgeon's recognition of this entity. Splenectomy is the most effective symptomatic treatment.

AIM:To compare the efficacy and safety of intravitreal ranibizumab to those of triamcinolone acetonide ( TA ) injection for the treatment of macular edema secondary to central retinal vein occlusion ( CRVO) .
METHODS:This retrospective study included 40 eyes of 40 patients with macular edema associated with CRVO. Twenty patients 20 eyes were treated with intravitreal injection of triamcinolone acetonide (1mg, 0. 1mL), the other 20 patients 20 eyes accepted intravitreal ranibizumab (0. 5mg, 0. 05mL). The change of best corrected visual acuity ( BCVA ) , central macular thickness ( CMT ) , and intraocular pressure ( IOP ) before treatment and at 1, 2wk, 1, 2,3,6mo post-injection in the two groups were observed.
RESULTS:BCVA was improved at 1, 2wk, 1, 2,3,6mo post-injection in the TA group (P<0.05) and ranibizumab group ( P<0. 05 ). No significant difference was found between the two groups ( P > 0. 05 ). CMT decreased significantly within each group ( P < 0. 05 ), and no significant difference between groups was found ( P >0.05). In the TA group, the IOP was significantly higher at 2wk and 4wk than before treatment (P<0. 05). In the ranibizumab group, no elevated IOP was observed at 1, 2wk, 1, 2,3,6mo (P>0. 05). However, the IOP at 1mo was significantly higher in the TA group than that in the ranibizumb group (P<0. 05).
CONCLUSION:Intravitreal ranibizumab is an effective and safe treatment method for macular edema secondary to CRVO. It can effectively improve BCVA and reduce CMT without ocular and systemic complications compared with intravitreal TA.

Objective To study the bioavailability and bioequivalence of erythromycin ethylsuccinate granules in healthy male volunteers.Methods In a randomized two-period crossover study,20 healthy male volunteers received single 500 mg test and reference formulations of erythromyein ethylsuccinate granules.The plasma concentrations of erythromycin were assayed by microbiological method.Results The parameters of test and reference preparations were as follows:T_(max)(0.86?0.22)and (0.80?0.13)h,C_(max)(2.13?0.64)and(2.16?0.61)mg/L,t_(1/2)(2.04?0.2)and(1.97?0.4)h,AUC_(0-t)(4.96?1.73)and(4.63?1.52)mg?h/L,respectively.There was no significant difference between the two preparations.The rela- tive bioavailahility of the test granules was(109.1?22.8)%.Conclusions The two preparations of erythromycin ethylsucci- nate granules are bioequivalent.

Objective To reveal evolution characteristics and antigenic epitope variabilities of hemagglutinin (HA) gene of H3N2 viruses in Guangdong during 2014-2015.Methods The HA gene nucleotide sequence of influenza H3N2 virus isolated during 2014-2015 in Guangdong Province was selected by spatial-temporal distribution.The HA gene nucleotide sequences were compared with global HA genes downloaded from GenBank and GISAID and the gene nucleotide mutations were analyzed.The phylogenetic tree and the entropy chart were conducted.Results Compared with HA gene of vaccine strain A/Texas/50/2012,the substitutions of 25 amino acid sites occurred in the HA gene of the 17 Guangdong strains during 2014 to 2015.The epitope A,B,D and E of the HA1 gene developed mutations,which involved 11 amino acid sites.One glycosylation site deletion occurred in A/Guangdong/ 55/2015 in virtue of the N38K site mutation.The high mutation site was at 175 with entropy value of 1.16.The 363 site might be the positive selection while the 368 and 425 sites might be the negative selection sites by comprehensive evaluation of the screening results of the single likelihood ancestor countincy (SLAC),fixed effects likelihood (FEL) and internal fixed-effects likelihood (IFEL) model.Conclusions The mutations emerge in the epitopes A,B,D and E of HA gene of the Guangdong H3N2 stains.Evolution at 363 site is positive selection while those at 368 and 425 sites are negative selection.The mutation accumulation might lead to the epidemic of influenza H3N2.

Objective To research the effects of short-term intensive insulin treatment on regaining the sensitivity of sulfonylureas in diabetes patients. Methods Thirty patients from outpatient and emergency department,including 12 male and 18 female,who took regular-dose sulfonylureas but was high blood glucose level,were selected to suspend the sulfonylureas treatment and were given the BIAsp30 to control the blood glucose level for three months,then they were stopped the BIAsp30 and took the same sulfonylureas used before.Results The average fasting blood glucose(FBG) was(9.4?7.5)mmol/L and the average postprandial 2 h blood glucose(PG2h)(or random blood glucose) was(14.2?7.2)mmol/L in 3 months before stopping the sulfonylureas.The average FBG was(5.7?0.7)mmol/L and PG2h was(7.2?1.4)mmol/L at the beginning of the insulin getting the blood glucose under control.The average FBG was(6.0?0.8)mmol/L and PG2h was (7.8?1.2)mmol/L during the insulin treatment.The average FBG was(6.1?0.6)mmol/L and PG2 h was(7.7?1.3)mmol/L at the end of the insulin treatment.The average FBG was(6.5?0.5)mmol/L and PG2h was(8.1?(0.8))mmol/L when continuing the sulfonylureas treatment in one months.It increased significantly to compare the blood glucose before the treatment of insulin to that after the treatment of insulin(P

AIM: To observe the surgical effects of the taumatic lens subluxation and cataract after manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation.
METHODS: A 3. 0mm tunnel limbus incision was operated through the predicted bulbar conjunctiva and sclera on 26 cases ( 26 eyes ) with taumatic lens subluxation ( suspensory ligament rupture range less than 120 ) and cataract (Ⅰ ~ Ⅲ) . And after the manual fragmentation and emulsification of nucleus, foldable intraocular lens was implantated. Intraocular lens loop was imbedded in the middle of the lens zonular ligament breakup to reset the pouch. The surgical complications and postoperative vision changes were observed.
RESULTS:Three month after operation, 22 eyes had a intraocular lens centric position taking up 85% of the whole. Four eyes had a slightly eccentric position ( 1 ~2mm), taking up 15% of the whole. 21 eyes had their visual acuity 0. 5~0. 8, taking up 81% of the whole. Five eyes of visual acuity was 0. 2~0. 8. Within 24h intraocular pressure of 12 eyes (46%) after operation were elevated, and returned to normal after 2~7d. There was no severe complication during operation and postoperation.
CONCLUSION: The manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation of the traumatic lens subluxation and the cataract through the 3. 0mm corneal sclera limbus tunnel incision is a simple and effective surgery.

Objective To explore the satisfaction of nurses on the work and patients on the nursing service after implementing the model of continuous scheduling and group-responsibility system,so as to to provide theories for improving nursing quality and human management.Methods Self-designed satisfaction questionaire was used to investigate nurses and patients before and after implementing the model of continuous scheduling and group-responsibility system,and nurses'satisfaction on the work and patients'satisfaction on the nursing care were observed and compared.Results The comprehensive satisfaction of nurses on the work in sixth,ninth,twelfth month after implementing the model of continuous scheduling and group-responsibility system was 91.0％,91.6％,92.3％,respectively which was higher than 80.6％ before implementing,and the difference was statistically significant ( x2 =4.74,5.56,6.40,respectively ; P ＜ 0.05 ).The satisfaction of patients on nursing increased from 90.1％ to 95.7％ after the model was implemented three to twelve months,which was significantly higher than 78.5％ before implementing( P ＜ 0.01 ).Night shift period was shortened and the nurses' satisfaction was decreased from 76.2％ to 61.8％ after the model was implemented ( x2 =6.95,P ＜ 0.01 ),while there was no difference in the situation of their mental pressure.Conclusions The scheduling revolution and group-responsibility system can provide no-gap and excellent nursing,and stimulate nurses' potential,and improve the nursing quality.But the situation of nurses' mental pressure is not improved for the lack of clinical nurses.
