? AlM: To evaluate the efficacy of the method of vitrectomy combined with posterior sclera reinforcement for retinal detachment due to macular hole in high myopia.
?METHODS:From January 2012 to December 2013, in 45 eyes of 45 high myopic patients with retinal detachment due to macular hole, 28 eyes were in group A of vitrectomy with posterior sclera reinforcement and 17 eyes were in group B of vitrectomy. Preoperative examinations included visual acuity, intraocular pressure, indirect ophthalmoscopy and OCT were performed. ln follow - up 6 to 12mo, postoperative examinations of visual acuity, OCT were performed and effects of retinal reattachment and macular hole closure were compared between the two groups.
?RESULTS: ( 1 ) Postoperative examinations: visual acuity was 1. 19±0. 39 in group A and 1. 51±0. 34 in group B. The differences were statistically significant(P<0. 05). (2) The retinal reattachment rate was 100% in group A and 88. 24% in group B. There was no statistical significance between them(P>0. 05). (3) The macular hole closure rate was 82% in group A and 53% in group B. The differences were statistically significant(P<0. 05).
? CONCLUSlON: The treatment of vitrectomy with posterior sclera reinforcement is safe and feasible, which could improve visual acuity and increase the rate of macular hole closure in treating retinal detachment due to macular hole in high myopia.

Objective To investigate the relationship between the number of colonies and the luminous intensity of two kinds of platelets contamination bacteria,Escherichia coli(ECO)and Pseudomonas aeruginosa(PAE)in single platelets, plasma and phosphate buffered salines(PBS), and to explore their growth and proliferation in different biological fluid media.Methods The two luminescent bacteria were constructed before the correlations between the number of colonies and the luminous intensity in different media in vitro were observed with a small animal bioluminescence imaging instrument, and correlation analysis was carried out.By recording the luminous intensity at serial time points in different media, a growth curve was drown to reflect the proliferation of bacteria.Results There was a significant positive correlation between the number of colonies and luminous intensity of ECO and PAE in single platelets,plasma and PBS.The larger the number of colonies was,the stronger the luminous intensity was.The results indicated that single platelets significantly inhibited the proliferation of ECO and PAE,and that plasma also had some inhibitory effect,but not so strong.Conclusion For the two luminous bacteria,luminous intensity can represent the growth and proliferation of bacteria.Single platelets have obvious inhibitory effect on the growth of ECO and PAE, and the plasma also has some inhibitory effect, but the effect is not so strong as that of single platelets.

This study is to explore new lead compounds by inhibition of Pin1 for anticancer therapy using temperature sensitive mutants. As Pin1 is conserved from yeast to human, we established a high-throughput screening method for Pin1 inhibitors, which employed yeast assay. This method led to the identification of one potent hits, 8-11. In vitro, 8-11 inhibited purified Pin1 enzyme activity with IC50 of (10.40 +/- 1.68) micromol x L(-1), induced G1 phase arrest and apoptosis, showed inhibitory effects on a series of cancer cell proliferation, reduced Cyclin D1 expression, was defined as reciprocally matched for protein-ligand complex in virtual docking analysis and reduced cell migration ability. In vivo, we could observe reduction of tumor volume after treatment with 8-11 in xenograft mice compared with vehicle DMSO treatment. Altogether, these results provide for the first time the involvement of 8-11 in the anticancer activity against Pin1.

BACKGROUNDProteins or peptides can be directly transferred into cells when covalently linked to protein transduction domains (PTDs). TAT is one of the most widely studied PTDs. The effect of fusion protein TAT and heme oxygenase-1 (HO-1) on liver sinusoidal endothelial cells (SECs) apoptosis during cold storage is unknown. The present study aimed to determine whether fusion protein TAT-HO-1 would transduce efficiently into liver during cold storage, and, if so, to determine whether TAT-HO-1 would attenuate SECs apoptosis during preservation injury in rat.

METHODSLivers of Sprague-Dawley rats were harvested and randomly assigned to group 1 (HTK solution) and group 2 (HTK solution containing TAT-HO-1 fusion protein) according to the type of the preservation solution. The transduction efficiency of TAT-HO-1 was examined and the impairment of SECs was assessed during the period of cold storage followed by 1 hour of reperfusion.

RESULTSTAT-HO-1 can transduce efficiently into liver during cold storage. A significantly lower apoptotic index of SECs was observed in group 2, at 6, 12 and 18 hours of cold storage after 1 hour reperfusion, when compared with group 1. TAT-HO-1 reduced HA and ET levels in liver at each time point. Both Bcl-2 and Bax protein were expressed in hepatocytes and SECs at the periphery of the sinusoidal space. Moreover, higher Bcl-2 expression and lower Bax expression were observed in group 2.

CONCLUSIONSTAT-HO-1 can transduce efficiently into rat livers and shows a protective effect on SECs by attenuating apoptosis during cold ischemia/reperfusion injury. Protein transduction will be a novel therapeutic strategy to reduce the risk of preservation injury in liver transplantation.

Objective To explore the method of health education to guide medication for the senile patients. Methods Fifty senile patients were divided into two groups;control group(n =25) and study group (n=25). The control group was given routine medication instruction while the study group performed medication instruction by using image pictures. Results The patients in the study group had dramatically improved the cognitive level of medicine. Conclusions The medication instruction of using image pictures is superior to the routine medication instruction.

OBJECTIVETo summarize the phenotypes and identify SCN1A mutations in families with generalized epilepsy with febrile seizures plus (GEFS(+)), and analyze the genotype- phenotype correlations in GEFS(+) families.

METHODGenomic DNA was extracted from peripheral blood lymphocytes of the proband and other available members in the GEFS(+) families. The phenotypes of the affected members were analyzed. The coding regions and flanking intronic regions of the SCN1A gene were screened for mutations using PCR and direct DNA sequencing.

RESULTIn 39 GEFS(+) families, there were 196 affected members, ranging from 2 to 22 affected members in each family. Their phenotypes included febrile seizures (FS) in 92(46.9%), febrile seizures plus (FS(+)) in 62(31.6%), FS or FS(+) with partial seizures in 12(6.1%), afebrile generalized tonic-clonic seizures (AGTCS) in 11(5.6%), myoclonic atonic epilepsy in 8(4.1%), Dravet syndrome in 2(1.0%), childhood absence epilepsy in 1 (0.5%), FS(+) with myoclonic seizures in 1(0.5%), AGTCS and myoclonic seizures in 1 (0.5%), partial seizures in 1 (0.5%), unclassified seizures in 5 (2.6%). Four families were found with SCN1A mutations, including three families with missense mutation (N935H, R101Q, G1382R) and one family with truncation mutation (C373fsx378). In three families with missense mutations, the phenotypes include FS, FS(+), FS(+) with partial seizures, and AGTCS. In one family with truncation mutation, the phenotypes included FS, FS(+), and Dravet syndrome. The mother of proband in the family with missense mutation (R101Q) and the father of proband in the family with truncation mutation (C373fsx378) were both somatic mosaicism. Both of their phenotypes were FS(+).

CONCLUSIONThe most common phenotypes of GEFS(+) were FS and FS(+), followed by the FS/FS(+) with partial seizures and AGTCS. The most severe phenotype was Dravet syndrome. SCN1A mutation rate in GEFS(+) was about 10%. Missense mutation was common in GEFS(+) families, few with truncation mutation. Few members of GEFS(+) families had somatic mosaicism of SCN1A mutations and their phenotypes were relatively mild.

BACKGROUNDThe prognosis for patients with gastric cancer and synchronous liver metastases is very poor. However, a standard therapeutic strategy has not been well established. The clinical benefit and prognostic factors after hepatic surgical treatment for liver metastases from gastric cancer remain controversial.

METHODSRecords of 105 patients who underwent gastrectomy regardless of hepatic surgical treatment for gastric cancer with synchronous liver-only metastases in our center between 1995 and 2010 were retrospectively reviewed.

RESULTSThe overall survival rate for the 105 patients was 42.1%, 17.2%, and 10.6% at 1, 2, and 3 years, respectively, with a median survival time of 11 months. Multivariate survival analysis revealed that the extent of lymphadenectomy (D) (P < 0.001), lymph node metastases (P < 0.001), extent of liver metastases (H) (P = 0.008), and lymphovascular invasion (P = 0.002) were significant independent prognostic factors for survival. Among patients who underwent D2 lymphadenectomy, those who underwent hepatic surgical treatment had a significantly improved survival compared with those who underwent gastrectomy alone (median survival, 24 vs. 12 months; P < 0.001). However, hepatic surgical treatment was not a prognostic factor for patients who underwent D1 lymphadenectomy (median survival, 8 vs. 8 months; P = 0.495). For the 35 patients who underwent gastrectomy plus hepatic surgical treatment, D2 lymphadenectomy (P < 0.001), lymph node metastases (P = 0.015), and extent of liver metastases (H1 vs. H2 and H3) (P = 0.017) were independent significant prognostic factors for survival.

CONCLUSIONSD2 lymphadenectomy plus hepatic surgical treatment may provide hope for long-term survival of judiciously selected patients with hepatic metastases from gastric cancer. Patients with a low degree of lymph node metastases and H1 liver metastases would make the most appropriate candidates. However, if D2 dissection cannot be achieved, hepatic surgical treatment is not recommended.

OBJECTIVETo study the expression changes of tumor necrosis factor-alpha (TNF-(alpha), interleukin-6 (IL-6), C-reactive protein (CRP), monocyte chemotactic protein 1 (MCP-1), and their correlation with obesity in 20 -50 years old population of phlegm-damp constitution (PDC) and of normal constitution (NC) using Luminex technique.

METHODSTotally 101 population were recruited from Health Examination Center of Puren Hospital from April to December 2011. Based on body mass index (BMI), the subjects were assigned to four groups, i.e., the obesity of PDC group (Group OBT, BMI > or = 24 kg/m2, 30 cases), the non-obesity of PDC group (Group NOBT, BMI < 24 kg/m2, 25 cases), the obesity of non-PDC group (Group OBNT, BMI > or = 24 kg/m2, 28 cases), the NC group (Group P, BMI < 24 kg/m2, 18 cases). The BMI and body fat percent (FAT%) were compared among the 4 groups. Serum levels of TNF-alpha, IL-6, CRP, and MCP-1 were measured with Luminex technique.

RESULTSBMI was significantly higher in Group OBT and Group OBNT than in Group NOBT and Group P (all P < 0.05). The FAT% was significantly higher in Group OBT and Group OBNT than in Group P (P < 0.01). The serum TNF-alpha level in Group OBT was higher than in Group P (P < 0.01). The serum CRP and MCP-1 levels were significantly higher in Group OBT, NOBT, and OBNT than in Group P (P < 0.05, P < 0.01). The score for PDC was positively correlated with TNF-alpha, IL-6, and MCP-1 levels (P < 0.05).

CONCLUSIONSAbnormal higher levels of inflammatory factors exist in 20 -50 years old population of PDC. Chronic inflammation exists in population of PDC and obesity people.
