AlM:To study the refractive status characteristics aftser cataract surgery and the correlation between preoperative anterior chamber depth ( ACD) and refractive status.METHODS: Ninety-six cases of patients with cataract were randomly divided into two groups. The patients in phacoemulsification group were treated with phacoemulsification combined intraocular lens ( lOL ) implantation while the patients in small incision group were treated by small incision extracapsular cataract extraction combined with lOL implantation. Changes in ACD and postoperative refractive status and refractive fully corrected value were counted and the correlation of them were analyzed .RESULTS: ACD of the phacoemulsification group s deepened 0. 74mm while that of the small incision group deepened 0. 78mm after treatment and there was no significant difference (P>0. 05). After operation, the ACD of two groups significantly deepened ( P<0. 05 ). The postoperative visual acuity of two groups were significantly better than the uncorrected visual acuity of two groups (P<0. 05). The postoperative refraction of two groups patients were mainly 0 ~ +1. 0D ( 41. 67% and 54. 16%) and+1. 25~+2. 0D (43. 75% and 33. 33%) (P>0. 05). CONCLUSlON: ACD is significant deepened after operation. Surgeon needs full consideration of changes to improve the refractive lOL calculation accuracy.

The expression of tumor suppressor gene p16INK4a in mouse endometrium during early pregnancy and its possible role in blastocyst implantation were investigated in the present study. Real-time fluorescent quantitative PCR (FQ-PCR) and immunohistochemistry were applied to detect p16INK4a mRNA and protein expressions in endometrium of un-pregnant and pregnant mice on day 2, 3, 4, 5, 7, respectively. In addition, p16INK4a antibody was injected into the horns of uteri in pregnant mice on day 3 and its effect during blastocyst implantation was detected in vivo. The higher expressions of p16INK4a mRNA and protein were observed in pregnant mice compared with that in un-pregnant mice, with a steady increase from day 2 to day 5 and reaching the maximal level on day 5 of pregnancy and then decreasing. p16INK4a antibody decreased the number of implanted blastocysts compared with that of saline-injected group. The results suggest that p16INK4a may be associated with apoptosis of luminal epithelial cells and decidual cells, coordinating decidualization of endometrium and invasion of trophoblastic cells. Thus, we presume that p16INK4a participates in the process of blastocyst implantation in mice.

OBJECTIVETo compare therapeutic effects of moxibustion at "heat sensitive points" and western medicine on perennial allergic rhinitis.

METHODSOne hundred and twenty cases were randomly divided into a moxibustion group and a western medicine group, 60 cases in each group. The moxibustion group were treated with moxibustion at "heat sensitive points" on the head-face, abdomen, waist and back, once a day; and the western medicine group with oral administration of Cetirizine Hydrochloride, 10 mg each session, once daily, 10 days constituting one course.

RESULTSThe total effective rate and the total effective rate for the cases of over effectiveness 3 months later were 85.0% and 86.3% in the moxibustion group and 63.3% and 50.0% in the western medicine group, respec tively, with significant or very significant difference (P < 0.05, P < 0.01).

CONCLUSIONMoxibustion at "heat sensitive points" is an ideal therapy for perennial allergic rhinitis with low recurrence rate.

Objective To compare the left ventricular function parameters of patients with sick sinus syndrome ( SSS ) and DDD pacemaker implantation during atrioventricular conduction ( AVC ) and right ventricular apex pacing ( RVAP ) mode . Methods Forty‐six consecutive patients with SSS who had undergone DDD pacemaker implantation were studied . Fifty volunteers were included as control group . Changing from AVC to RVAP mode ,the acute effect on echocardiographic parameters ,including LVEF , parameters of aortic/pulmonary artery pulse wave Doppler ,and parameters of left ventricular twist by speckle tracking imaging were measured respectively . Pacemaker implantation duration and cumulative ventricular pacing proportion ( Cum% VP) were recorded . The relationships of pacemaker parameter and above left ventricular function parameters were analyzed . Results Compared with control group ,values of peak rotation in LV apex and LV twist were significantly lower during AVC and RVAP mode . The value of peak rotation in LV base showed no significant difference between three groups .Apical‐basal rotation delay during RVAP was significantly longer than those during AVC and in control group respectively ( P <0 .05) . LVEF during RVAP decreased statistically ( P< 0 .05 ) ,but showed no difference during AVC , compared with the control group . The peak LV twist related positively with LVEF ,and negatively with Cum% VP . Conclusions RVA pacing decreases left ventricular function , which is independent of asynchrony contraction patterns caused by pacing . LVEF ,apical rotation and LV twist are more sensitive to demonstrate the LV dysfunction in patients with pacemaker implantation . LV twist related negatively with Cum% VP .

Objective To investigate a more perfect method for a nice outward appearance of the thumb(finger) reconstructed.Methods An artery pedicle composite flap from fibular side of the great toe is inlaid in the tibial(ventral) side of the free second toe for thumb reconstruction and the same free second toe with a distal part of metatarsal bone with a double-wings flap for finger reconstruction before transplantation. Results The reconstructed thumb(finger) gets a nice looking and normal function while no blight to the great toe occurred.Conclusion It is an effective new procedure in ameliorating outward appearance of the recon- structed thumb(finger) by transferring the free moulded second toe.

Objective:To observe the clinical efficacy of balance-impact tuina therapy for lumbar intervertebral disc herniation (LIDH).Methods:A total of 118 eligible LIDH patients were randomized into an observation group and a control group by the random number table method,with 59 cases in each group.The observation group was intervened by balance-impact tuina therapy,while the control group was intervened by conventional tuina therapy,both for consecutive two weeks.The scores of visual analog scale (VAS),Oswestry disability index (ODI),quality of life questionnaire-core 30 (QOL-C30) were observed before and after treatment;the relapse rate was estimated at the sixth month and twelfth month following the treatment.The data were statistically analyzed.Results:After intervention,the total effective rate was 96.6％ in the observation group versus 91.5％ in the control group,and the between-group difference was statistically significant (P＜0.05).The VAS and ODI scores declined significantly after treatment in both groups (all P＜0.05),and the observation group was markedly lower than the control group (P＜0.05,P＜0.01).The QOL-C30 score increased significantly after treatment in both groups (both P＜0.05),and the observation group was markedly higher than the control group (P＜0.05).The relapse rates at the post-treatment sixth month and twelfth month in the observation group were lower than those in the control group (P＜0.05,P＜0.01).Conclusion:Compared with the conventional tuina therapy,the balance-impact tuina therapy shows advantage in lessening pain,improving the function and enhancing the quality of life in the treatment of LIDH,and it has a lower relapse rate.Thus,this therapy is worth promoting in clinic.

OBJECTIVETo investigate the relationship between the polymorphic (AT)n repeats in 3ountranslated region of exon 4 of CTLA4 gene [CTLA4(AT)n] and Graveso disease (GD) in Zhuang nationality population of Guangxi province.

METHODSThe studied groups comprised 48 patients with GD and 44 normal controls. Amplification of target DNA was carried out by polymerase chain reaction (PCR). The amplified products were run by 8% polyacrylamide gel electrophoresis, and then followed by 0.1% silver staining. Some of amplified products were sequenced directly.

RESULTSNineteen alleles of CTLA4 gene microsatellite polymorphism were found in Guangxi Zhuang nationality individuals. The 106 bp long allele was apparently increased in patients with GD of Zhuang nationality but not in healthy controls (P< 0.05).

CONCLUSIONCTLA4 gene microsatellite polymorphism is strongly associated with Graveso disease in Zhuang nationality population of Guangxi province. CTLA4(AT)n 106 bp may be the susceptible gene in GD patients of Zhuang nationality in Guangxi; 19 alleles of CTLA4 gene microsatellite polymorphism were found in Guangxi Zhuang nationality individuals.
