Background Many surgical techniques are used to improve the postoperative visual acuity for rhegmatogenous retinal detachment(RRD)during recent decade,and scleral buckling surgery is one of these operations.Whether the visual function after operation can be rescued is an important issue. Objective The aim of this study was to analyze the risk factors of influencing the postoperative vision following scleral buckling surgery for primary macula-off RRD. Methods The clinical and follow-up data from consecutive series of 116 eyes of 116 patients received scleral buckling surgery for primary maeula-off RRD were retrospectively reviewed.The relationship of multiple factors,including age,preoperative best corrected visual acuity(BCVA),duration of disease,refractive error,location of retinal hole,number of retinal hole,area and height of retina detachment,management of subretinal fluid and intravitreal gas injection,with visual acuity were analyzed respectively by χ2 test.The correlations among statistically significant factors with postoperative vision were analyzed by multivariate Logistic regression analysis.Written informed consent was obtained from any patient before surgery. Results The postoperative vision outcome was found with significantly difference among different preoperative vision groups(P=0.002)and different course (P=0.009).There were significant differences between the groups with different preoperative BCVA(P=0.002)and duration of disease(P=0.009).Multivariate Logistic regression analysis showed that the preoperative BCVA was the only variable affecting postoperative visual result(r=0.400,P=0.009).Considerable linear correlation wag seen between preoperative vision and postoperative vision(r= 0.400,P=0.000).The probability with postoperative vision of t>0.4 in the eyes with preoperative≥0.05 was 3 folds more than that of preoperative<0.05(OR=2.992).The better visual outcome after scleral buckling surgery was seen in the eyes with the course≤7 days. Conclusion Preoperative BCVA and duration of disease are the key factors associated with the postoperative BCVA.Scleral buckling surgery should be performed within the first week for primary macula-off RRD.

Background The pathogenesis of pterygium has been in the study.Relative molecular biology study showed that pterygium is a tumor-like lesion,and based on overseas literatures,human papillomavirus (HPV) is positively expressed in 100％ patients with pterygium in some region.However,if this result is suitable for Chinese patients is unclear.Objective This study was to identify the role of human HPV in the pathogenesis of pterygia in Wuxi area.Methods Forty-eight pterygium specimens including 7 recurrent pterygia and 41 primary pterygia were collected during the operation,and these patients were from Wuxi area.Two cervical carcinoma specimens and 2 conjunctiva specimens from normal donors were obtained as positive control and negative control respectively.The fluorescent quantitative polymerase chain reaction (FQ-PCR) was used to detect HPV DNA of specimens.Results The amplified curves of HPV 6,11 of pterygium specimens,cervical carcinoma specimens and normal specimens were all below the positive quality control curve,but the amplified curves of HPV16,18 were above the quality control curve in cervical carcinoma specimens; while those of pterygium specimens and normal conjunctival specimens were all below the quality control curve.HPV16/18 was identified in 2 cervical carcinoma specimens,but no HPV6/11 was detected in 2 cervical carcinoma specimens.However,HPV DNA expression in primary and recurrent pterygias were absent.Conclusions According to these results,HPV is not the primary cause for the pathogenesis of pterygium in Wuxi region.

AlM:To compare the functional and cosmetic effects of two different surgical techniques for congenital ptosis.
METHODS: The patients were divided into four groups according to the operation method: Patients undertook bilateral fascial suspension surgery as Group A ( 42 eyes of 21 cases ); Patients undertook bilateral levator muscle shortening surgery as Group B ( 38 eyes of 19 cases );Patients undertook unilateral fascial suspension surgery as Group C ( 24 eyes of 24 cases ); Patients undertook unilateral levator muscle shortening surgery as Group D (29 eyes of 29 cases). Each group patients were followed for postoperative function and appearance effect.
RESULTS: 1 ) Early postoperative of two operation function success rate was up to 100%, the function of levator muscle shortening surgery was 97. 01% in the late postoperative, was higher than bilateral fascial suspension surgery (87. 88%), with statistical difference in both surgerys (P<0. 05). 2) Appearance effect of two kinds of operation method in early postoperative had no statistical difference (P >0. 05); ln the late postoperative, the mean grades for “Lid Contour” and “Lid Crease” of Group B were better than that of Group A (P<0. 01). While the mean grades for “Lid Contour”, “Symmetry of Lid Height” and “Lid Crease” of Group D were similarly better than that of Group C (P<0. 01).
CONCLUSlON: Two kinds of operation method have good effects on the treatment of congenital ptosis. ln terms of cosmetic effect, levator muscle shortening surgery is better.

Spermatogenesis is a complex developmental process in which a diploid progenitor germ cell transforms into highly specialized spermatozoa. During spermatogenesis, membrane remodeling takes place, and cell membrane permeability and liquidity undergo phase-specific changes, which are all associated with the alteration of membrane lipids. Lipids are important components of the germ cell membrane, whose volume and ratio fluctuate in different phases of spermatogenesis. Abnormal lipid metabolism can cause spermatogenic dysfunction and consequently male infertility. Germ cell membrane lipids are mainly composed of cholesterol, phospholipids and glycolipids, which play critical roles in cell adhesion and signal transduction during spermatogenesis. An insight into the correlation of membrane lipids with spermatogenesis helps us to better understand the mechanisms of spermatogenesis and provide new approaches to the diagnosis and treatment of male infertility.

Objective To analyze the performance of adsorbing CO2 with zeolite 5A molecular sieve in crew module. Methods Fitting analysis was based on experimental data of adsorbing CO2,O2 and N2 with zeolite 5A molecular sieve and the suitability of isotherm adsorbing equation of Langmuir,Freundlich and BET models to be conducted with Origin software. Then using obtained equations and competitive adsorbing theory,the adsorbed amounts of these three kinds of gas under competitive condition were calculated. Results The constants in equations for adsorbing CO2,O2 and N2 with zeolite 5A molecular sieve were determined,and adsorbed amounts for above three kinds of gases under competitive condition were calculated. Conclusion The adsorbed CO2 amount is affected by high fraction of N2. Therefore zeolite 5A molecular sieve should be modified technically so that its adsorption in N2 might be reduced to an ignored amount.

BACKGROUND: Electroacupuncture has a good clinical effect on Alzheimer disease, but its mechanism remains unclear.OBJECTIVE: To observe the effect of electroacupuncture on number of synaptic numeric density (Nv), surface density (Sv) and average size of synaptic conjunction and ultrastructure in hippocampal CA3 area of neurons of model rats with Alzheimer disease (AD).DESIGN: Completely randomized grouping and controlled study.SETTING: Department of Traditional Chinese Medicine of Sichuan Provincial People's Hospital; College of Acupuncture & Moxibustion and Massage of Chengdu University of Traditional Chinese Medicine.MATERIALS: A total of 50 male SD rats of 24-month old weighing (480±20) g and 6 male rats of 3-month old weighing (250±15) g were selected in this study. Passage water maze (2.1×1.7×0.6) m3 was made of black glasses with 40 cm deep water and 4 caecums. WQ1002F Hans electrically heated distilling apparatus was used.METHODS: The experiment was carried out at the Grade Ⅲ Animal Experimental Center of Chengdu University of Traditional Chinese Medicine between, September 2002 and June 2003. ① Old SD rats were grouped on the basis of water-maze test results. Firstly, 6 young rats were submitted to water-maze test at 8 days before modeling for 4 continuous days to obtain average escaping latency. Secondly, 50 old rats were accepted in the water-maze test at 4 continuous days before modeling to obtain average escaping latency. A total of 36 rats whose latencies were less than average values plus one standard deviation of young rats were regarded as normal old rats. Among them, 12 rats were randomly divided into control group and sham operation group with 6 in each. Another 24 rats were transected at fornix-fimbria AD modeling. Thirdly, 24 modeling rats were all adopted in the water-maze test at 2 days after modeling. Rats whose latencies were more than average value plus two standard deviation of young rats were chosen as AD model. Twelve AD models were randomly divided into model group and electroacupuncture group with 6 in each.② On the 6th day after modeling, rats in electroacupuncture group were acupunctured at Baihui (Du20) of 0.5 inch in slope, Yongquan (K1),Taixi (K3) and Xuehai(Sp10) of 0.3 inch in depth with No. 30 milli-needle (3.33 cm); Then, electrically heated distilling apparatus was used with successive waves, 20 Hz in frequency and 2-4 V in voltage. Tolerant stress of rats at quiet state was regarded as the standard value (2 mA),the needle was maintained for 30 minutes, and the acupuncture was done once a day for totally 20 successive days. Rats in control group sham operation group (cerebral cortex was exposured at the same site as model rats, and fornix-fimbria was not cut off) and model group were only fixed but treated with nothing. ③ After treatment, ultrastructure in hippocampal CA3 area of rats was observed with transmission electron microscope;synapse numbers and cross-point numbers between synaptic conjunction and test line were counted with stereological technique; stereological parameters, such as numeric density (Nv), area surface (Sv) and average size of synaptic conjunction, which could reflect plastic changes of synaptic form, were calculated at the same time. ④ Differences between every two groups were compared with t test at regular variance and t'test at irregular variance.MAIN OUTCOME MEASURES: Comparisons of numeric density (Nv),surface density (Sv) and average size of synaptic conjunction.RESULTS: A total of 24 old rats were involved in the final analysis with 6 in each group. ① Ultrastructure: Synaptic density of control and sham operation group was higher than that of model group, and average area of synapse was smaller;, synaptic density of electroacupuncture group increased compared with that of model group, and average area of synapse was smaller. ② Numeric density and surface density in hippocampal CA3 area in model and electroacupuncture group were lower than those of control group and sham operation group (P ＜ 0.05). There was no significant difference between sham operation group and control group (P ＞ 0.05), and those of electroacupuncture group were higher than those of model group (P ＜ 0.01). ③ Average size of synaptic conjunction in hippocampal CA3 of model and electroacupuncture group was higher than that of control and sham operation group (P ＜ 0.05). There was no significant difference between sham operation group and control group (P ＞ 0.05), and the value of electroacupuncture group was lower than that of model group (P ＜ 0.01). CONCLUSION: Electrotherapy can repair synaptic form and inhibit synaptic degeneration of hippocampal neurons in AD rats.
