Autosomal dominant optic atrophy(ADOA),also called Kjer-type optic atrophy,is the most decrease of visual acuity,color vision deficit,visual field defects,and it is also characterized by temporal pallor of the optic disc.Deafness,cataract,ophthalmoplegia,ptosis and so on,can also accompany ADOA.Up to now,it has been verified that four known genetic loci are associated with ADOA,including OPA1(3q28-29),OPA3(19q13.2-13.3),OPA4(18q12.2-12.3)and OPA5(22q12.1-13.1).The OPA1 and OPA3 genes have been cloned.But genotypephenotype correlations and pathogenic mechanisms of ADOA are not very clear.The recent researches about clinical features,relevant candidate gene and loci,differentiation diagnosis were reviewed.

In recent years, the incidence and mortality of colorectal cancer have gradually increased in China. This review sum-marized the differences in pathogenic factors, clinical manifestations, pathological features, gene expression, therapeutic modalities, and other aspects between left-and right-sided colon cancers. Results showed that the onset of both left-and right-sided colon cancers is associated with gender and age. Significant differences existed among the clinical manifestations and pathological features. Differenc-es in gene expression, allelic deletion, and DNA mismatch repair affected the occurrence, metastasis, and prognosis of left-and right-sided colon cancers. Moreover, the location of primary tumor is a potential predictor of targeted drug efficacy. Differences in survival rates are possibly related to TNM stage. Hence, new ideas for individualized treatment should be provided by analyzing the differences between left-and right-sided colon cancers.

OBJECTIVETo study cellular and humoral immune status on prophase of severe hepatitis B (PSHB).

METHODS56 cases of PSHB patients, 40 cases of chronic hepatitis B (CHB) patients and 20 cases of healthy volunteers were enrolled for detection of CD3+, CD4+, CD8+ and CD3-/CD19+ (B cells) lymphocyte subsets in peripheral blood by flow cytometry. Serum IgG and complement C3 was detected by immunoturbidimetry and analyzed statistically.

RESULTSCompared with CHB group and healthy control group, percentage of lymphocyte subsets CD8+ were significantly lower in PSHB group (P < 0.01 or P < 0.05). While the percentage of lymphocyte subsets CD4+ and ratio of CD4+/CD8+ in PSHB group was obviously higher than those in CHB group (P < 0.+01 or P < 0.05). In addition, There was no significant difference on the percentage of B cell and level of serum IgG between PSHB group and CHB group (P > 0.05, while the level of serum complement C3 in PSHB group were significantly lower than those in CHB group and healthy control group (P < 0.01, P < 0.05).

CONCLUSIONPSHB has a certain degree of cellular immune dysfunction, which characterized by cellular immune function hyperfunction and humoral immune suppression.

Objective To explore clinical diagnosis and surgical treatment for the traumatic liver rupture.Methods The clinical data of 60 cases with traumatic liver rupture were retrospectively cralyzed to explore the diagnosis and surgical treatment.Results 45 injury patients were diagmosed by,patient history,signs and imaging studies.15 cases of blunt injury,five cases diagnosed by above methods,10 cases of diagnostic peritoneal puncture are positive diagnosis.28 cases received the left hepatic lobe partial resection,20 cases right lobe partial resection,12 cases had the left hepatic lobe and right lobe partial nephrectomy.Among 60 patients,5 cases(8.33％) were dead and the other 55 patients,8 cases occured postoperative complications,were discharged after symptomatic treatment,the average length of stay was (15.6 ± 3.5) days.Conclusion Traumatic liver rupture is a critical illness,rapid and correct diagnosis before surgery,and choose the correct surgical approach,focusing on merger deal with injuries to postoperative complications,and improve the treatment success rate.

Objective To evaluate the effect of therapeutic touch on continuous positive airway pressure titration with obstructive sleep apnea hypopnea syndrome (OSAHS) patients.Methods Fortyeight patients diagnosed with OSAHS were randomly allocated to the therapeutic group and the control group with 24 patients in each group.Therapeutic touch was used in the therapeutic group before CPAP titration and the control group received usual care.Anxiety was measured post intervention with State-trait Anxiety Inventory(SAI) and Visual Analogue Scale(VAS).CPAP therapy satisfaction was also evaluated by VAS.Results Compared with the control group,those patients with therapeutic touch showed significant reductions in SAI scores,better sleep quality,and higher satisfaction with CPAP treatment.Conclusions Results suggest that 15-min of therapeutic touch pre CPAP titration night significantly reduced anxiety and improved sleep quality in patients with OSAHS.

Objective To investigate the change of plasma cholinesterases (CHEs) in the people with diabetes or fatty liver or overweight , and explore the role of CHE in these diseases .Methods The plasma CHEs in 2834 subjects were detected , and these subjects were divided into five groups , including diabetes , fatty liver , overweight , diabetes with fatty liver , and the normal groups . Results The plasma CHE activities in diabetes group , fatty liver group , overweight group , and diabetes with fatty liver group were all higher than the normal group [(8943 ±1896)U/L, (9716 ±1673)U/L, (8798 ±1710)U/L, (9385 ±1687)U/L vs (8028 ±1621) U/L], and the CHE level in the fatty liver group was highest among five groups .However, the CHE level in diabetes group or fatty liv-er group was not significantly different from that in the diabetes with fatty liver group .The CHE level of the people with components of metabolic syndrome (MS) was significantly higher than that without MS component [(8786 ±1514)U/L, (9141 ±1771)U/L, (9705 ±1628)U/L, (9138 ±1768)U/L, (9530 ±1607)U/L vs (7821 ±1324)U/L]),but the CHE level was not increased gradually with the increased MS component.The plasma CHE had a negative correlation with age ( P =0.00),but it had a positive correlation with triglyceride (TG), total cholesterol (TC), and body mass index (BMI)( P =0.00).Conclusions The plasma CHE activity was el-evated in diabetes group , fatty liver group , and overweight group , which might be a risk factor in these diseases .Controlling the plas-ma CHE might help to treat the metabolism diseases .

Objective To study the mechanism of FTY720 on type Ι diabetic rats. Methods The typeⅠdiabetes rat model was established by feeding male SD rats with high energy urea and injecting into the abdominal cavity with low dose cephalosporins (STZ, 30 mg/kg). In the following, the treated rats were divided into two groups: model group and FTY720 group. Another group of untreated rats was assigned as normal control group. FTY720 group was given 1 mg/kg FTY720, the normal control group and model group was given the equal amount of water. Results The cardiac function of FTY720 group was recovered markeyly. FTY720 activated the expression of vascular endothelial cells S1P1 , diabetes and reduced the expessions of S1P3 and PKCβ Ⅱand it restored the migration ability of diabetes cardiovascular endothelial cell , as well as the abnormally elevated cardiovascular endothelial cells induced by high sugar permeability. Conclusion The S1P1 and S1P3 cut is an important reaction pathway to the complications of diabetes and cardiovascular dysfunction. FTY720 may reduce the damage to core blood vessels caused by diabetes , and pathological angiogenesis which functionally depends on the PKCβⅡ signaling pathways. Therefore, FTY720 may provide a potential therapy for cardiovascular function impaired by diabetes.
