AIM: To study the clinical effect of implantation of multifocal intraocular lens ( lOL ) combined with cataract extraction and lOL in cataract patients.
●METHODS:A total of 86 cases ( 86 eyes ) of cataract patients admitted to our hospital from Feb. 2014 to Mar. 2015 were divided into two groups according to the order of admission, each of 43 cases. The 43 patients with cataract extraction combined with non spherical astigmatism correction type monofocal lOL implantation for the treatment as the control group, the other 43 patients with cataract extraction combined with aspheric toric multifocal lOL implantation were treated as the observation group. After 1y of follow- up, the visual acuity, astigmatism and the contrast sensitivity of the two groups were observed.
●RESULTS: There was no difference in visual acuity between two groups (P>0. 05). Postoperative observation group of uncorrected near visual acuity ( UCNVA ) was significantly better than the control group (P<0. 05), and the other indexes were not different (P>0. 05). There was no difference in astigmatism between the two groups before and after operation ( P> 0. 05 ). There was no difference in contrast sensitivity between two groups ( P>0. 05). The contrast sensitivity of the control group was better than that of the observation group (P<0. 05), and the rest had no difference (P>0. 05).
● CONCLUSION: Astigmatism correction multifocal intraocular lens on corneal astigmatism after surgery has a good effect, the naked eye near visual effect is better, the rest of the visual acuity is stable, good visual quality, worthy of clinical application and promotion.

Objective To investigate the association between carotid atherosclerosis(AS) and serum magnesium(Mg) in hemodialyzed (HD) patients.Methods Clinical index was measured,and intimamedia thickness (IMT) of extracranial common carotid artery and presence of atherosclerotic plaques were determined by high-resolution B-mode ultrasonography.The data were analyzed between plaque positive group and plaque negative group.Results The age,serum phosphate (P),total cholesterol (TCH),low density lipoprotein (LDL),serum C-reactive protein (CRP),serum albumin(Alb),and serum Mg all had significant difference between two groups(t =4.153,2.908,2.301,6.322,5.791,2.341,7.778,P ＜0.01 or P ＜ 0.05).The risk factors of HD patients with AS were serum Mg and CRP(P ＜ 0.01).Conclusions The occurrence of AS was related to low Mg and high CRP in HD patients.

OBJECTIVETo observe the efficacy of Modified Xiaoyao Decoction (MXD) combining clomipramine in treatment of depression.

METHODSOne hundred and five depression patients were randomly assigned to two groups. The treated group (53 patients), all were differentiated as Gan-qi stagnation syndrome type and treated with MXD combining clomipramine 25-50 mg/d. The control group (52 patients) treated with clomipramine 75-225 mg/d alone. The treatment lasted for 8 weeks in both groups. Scores of depression was assessed with Hamilton Depression Scale (HAMD) before treatment and at the 2nd, 4th, 8th week of the treatment, efficacy and adverse reactions were evaluated with Global Impression of Change (CGI) and Treatment Emergent Symptom Scale (TESS) respectively.

RESULTSAfter treatment the scores in both groups were significantly different from those before treatment (P < 0.01), but no significant difference was found between the two groups (P > 0.05). Main adverse reactions were dry mouth, constipation in the treated group, much less than those in the control group, which were mainly dry mouth, constipation, dizziness, insomnia, blurred vision and prolonged Q-T interval (P < 0.01).

CONCLUSIONMXD combining clomipramine has the efficacy on depression similar to clomipramine, but has less adverse reactions.

Metabolic engineering provide powerful tools for the systematic manipulation of cellular metabolic activities. The ptsG gene for glucose-specific transporter Enzyme II CBGlc of the phosphotransferase system was knock-out so as to reduce the accumulation of acetic acid in the high cell-density culture of Escherichia coli on excess glucose. The chloramphenicol-resistant cassette with short shared sequences on both ends generated by PCR was electroporated into Escherichia coli DH5alpha and JM109. Recombination between linear DNA cassettes and Escherichia coli chromosomes took place by Red recombinase functions. Therefore, the ptsG gene was disrupted to construct the mutants called DH5alphaP and JM109P. There was no difference between the mutants and parent strains in LB media.However, in LB media supplemented with glucose, the mutants of Escherichia coli deficient in ptsG showed greater biomass, together with exploiting more glucose. The maximal cell density obtained with DH5alphaP was approximately 3 times more than that of DH5alpha, then the result of JM109P increased fourfold. The products of recombinant protein TNF respectively accounted for 24.3% of total cellular protein in DH5alphaP with A600 8.28 and 20.8% of total cellular protein in JM109P with A600 7.62. The specific volume expression amount of TNF was greater in the ptsG mutant than in its parent strain. These results demonstrate that the ptsG-mutant strains will be available for high cell-density culture.

Objective To investigate the MRI features of supratentorial solid hemangioblastoma and to improve its diagnostic accuracy.Methods MRI image manifestations of 7 cases with supratentorial solid hemangioblastoma confirmed by operation and pathology were analyzed retrospectively.Results 7 cases of supratentorial solid hemangioblastoma were solitary.All tumors appeared as round or quasi-round masses with clear boundary, and showed equal or long T1 signal and slight long or long T2 signal,the obvious enhancement was seen in all tumors.There was mild to moderate edema around the tumors.The blood vessel was found within or around the tumors.Conclusion MRI manifestations of supratentorial solid hemangioblastoma have certain characteristics.

The purpose of this study is to systematically investigate the characteristics of absorption and metabolism of oxymatrine (OMT) using rat intestinal perfusion model. Ultra performance liquid chromatography (UPLC) and high performance liquid chromatography-electrospray ionization-quadrupole-time of flight mass spectrometry (HPLC-ESI(+)-Q-TOF-MS) were used to test absorption of OMT in intestine at 100, 200 and 400 µmol · L(-1). The absorption rate and permeability of OMT is not dependent on concentration, but through passive absorption in intestine (P > 0.05). In the rat intestine, the absorbed amount of OMT was significantly different in four sections of the intestine in an order of duodenum > jejunum > ileum > colon (P < 0.05). OMT is metabolized into two metabolites in duodenum and jejunum, and matrine (MT) is the major one.

Objective To study the relationship between the type of histopathology and prognosis of contained mucous adenocarcinoma(CMAC) of stomach and its clinical significance. Methods Eighty-seven cases of CMAC of stomach were observed by means of pathomorphology, histochemistry, immunohistochemistry and follow up etc. Results The malignant behavior of the cancer was significant difference according to the nature and quantity of the CAMC and the primary pathological type of the cancer.The clinical type in simple mucous carcinoma was mainly Borrmann type I;in tubular papilla mucous adenocarcinoma was mainly Borrmman type II; in signet-ring cell mucous carcinoma was mainly Borrmman type IV,and in mixed cell mucous carcinoma was mainly Borrmman type III. There was significant difference in the lymphatic metastasis and survival rate between the 4 groups. Conclusions Correct differentiation of the pathological type of contained mucous adenocarcinoma of stomach is important for guading the treatment and predicting the prognosis.Cathepsin D expression can help for understanding the biological behavior of CMAC of the stomach.
