Objective To compare the changes of corneal endothelial cells in early recovery period after 1.8 mm small incision phacoemulsification nucleus chopping and conventional incision phacoemulsification for cataract.Methods Fifty-three patients with cataract were divided into the observation group and control group according to different operation methods.The observation group was treated with 1.8 mm small incision phacoemuisification nucleus chopping while the control group was treated with routine incision phacoemuisification.The visual acuity,degree of astigmatism,corneal endothelial cell indexes and complications were observed.Results The effective ultrasound time and average ultrasonic energy of the observation group were significantly less than those of the control group (all P ＜ 0.05).Compared with 1 day before operation,the visual acuity,degree of astigmatism,corneal endothelial cell area (ECA) and coefficient of variation (CV) were significantly increased at 1 week and 4 weeks after operation,and corneal endothelial cell density (ECD) was significantly decreased (all P ＜ 0.05).The visual acuity and ECD levels of the observation group at 1 day,1 week and 4 weeks after operation were significantly higher than those of the control group,while the degree of astigmatism,ECA and CV were significantly lower than those of the control group (all P ＜ 0.05).Conclusion Compared with the traditional incision phacoemulsification,the damage of 1.8 mm small incision phacoemulsification nucleus chopping to corneal endothelial cells is significantly milder,can reduce the effective ultrasound time and average ultrasonic energy,decrease the degree of astigmatism,improve the visual acuity and decrease the corneal edema.

Through the questionnaire survey of 2,000 patients with dysmenorrhea, the clinical characteristics of dysmenorrhea were investigated, and the reference basis for preventing and controlling dysmenorrhea was provided. The results found that the age of menarche, short menstrual cycle, by volume, long period of time has no obvious relationship with the occurrence of dysmenorrhea. Dysmenorrhea main influence factors to feel cold; syndrome (symptoms) characteristics for the actual situation inclusions mainly, with severity, deficiency symptoms more obvious; in different degrees of dysmenorrhea, frequency of belly chills symptoms appear most, and cold coagulation and blood stasis syndrome (symptoms) appear higher frequency; The type of cold coagulation and blood stasis dysmenorrhea was 53.2%. Dysmenorrhea measures to select bed rest most, accounting for 79.6%. For severe dysmenorrhea in patients with drug choice to traditional Chinese combined with western medicine accounted for 43.4%. Selection of Chinese medicine formulations in patients with dysmenorrhea Decoction formulation accounted for the most 26.5%. The survey results, to avoid cold and have a positive effect on the prevention of dysmenorrhea, dysmenorrhea treatment should pay attention to warming channels to dispel cold.

Objective To observe the effects of aging on liver and heat shock protein (HSP)70 expression in rats,and explore the role of HSP 70 in the changes of aging liver. Methods 24 healthy Sprague Dawley rats were divided into 4 groups according to age:21-day-old group,3-monthold group,12-month-old group and 18-month-old group (n=6 per group).Routine blood tests and biochemical tests were tested. Liver tissues were observed under light microscopy. The mRNA expression of HSP70 was detected by real-time PCR. Results The ratios of liver weight to body weight were decreased gradually with aging in 4 groups (0.073,0.050,0.025,0.019,respectively,t=78.016,P =0.000).Compared with those of young rats (21-day-old and 3-month-old),serum albumin levels of aged rats (12-months and 18-months) were declined [(35.0±2.7) g/L and (39.8±3.5) g/L vs.(27.3±9.3) g/L and (20.6± 1.7) g/L,t=12.233,P=0.000].Nevertheless serum alkaline phosphatase (ALP) levels were increased with aging [(68.8± 23.3) U/L,(71.6 ± 19.2)U/L,( 185.9 ± 41.5) U/L,(418.6 ± 140.6) U/L,respectively,t =35.454,P=0.000].The differences in other routine biochemical indexes were not found among the age groups (P＞0.05).Liver histological changes including hepatocytes disordered and vacuolization or fatty changes were detected with aging,especially in 18 month-old rats. Real-time PCR results indicated that the expression level of HSP70 mRNA was much lower in 18-month-old rats than in 12-month-old and 3-month-old rats (0.218 vs.0.220 and 0.230,P=0.000). Conclusions HSP70,as a stress protein,may play an important role in the procedure of injury and senescence of liver cell,and then can serve liver aging as one of the influential markers.

Objective To preliminarily explore the delineation of clinical target volume in intensity-modulated radiotherapy for para-aortic lymph node metastases in patients with gynecological malignancies.Methods A retrospective analysis was performed on 56 gynecological tumor patients with para-aortic lymph node metastases who were admitted to our department from January 2010 to September 2016.The number and distribution of metastatic para-aortic lymph nodes were determined by imaging method.Results A total of 108 positive para-aortic lymph nodes were found in the 56 patients,with 1-4(mean,2) positive para-aortic lymph nodes per patient.The mean diameter of positive para-aortic lymph nodes was 2.3 cm (1.2-4.0 cm).A total of 20 metastatic lymph nodes (19%) were located at the L4 level,38(35%) at the L3 level,44(41%) at the L2 level,and 6(5%) at the L1 level.There were 71 metastatic lymph nodes (66%) at the left side of the para-aortic region,20 metastatic lymph nodes (19%) between the abdominal aorta and the vena cava,and 17 metastatic lymph nodes (15%) at the right side of the inferior vena cava.Conclusions For patients with gynecological malignancies,nodal contouring for the para-aortic region should not be defined by a fixed circumferential margin around the vessels.The left side of the para-aortic region should be covered adequately;the upper target should be extended up to the renal artery,and needs to be further extended for patients who have nodal involvement near the renal arteries and veins.

OBJECTIVE: To study the antidepressant effects of total flavone of A( TFA) on post stroke depression ( PSD) in rats. METHODS: Middle cerebral artery occlusion ( MCAO) followed by isolation feed and irritable stimuli was used to induce PSD. Behaviours of rats were detected by open- field test . The effects of TFA on the indexes of hemorheology and brain homogenate lipid peroxidation were also tested. RESULTS: TFA could increase the crossing and rearing scores in open- field test, inhibit the elevation of whole blood viscosity as well as plasma viscosity at high- middle- low shear rates, increase the erythrocyte deformation, enhance the activities of Superoxide Dismutase ( SOD) and Glutathione Peroxidase ( GSH- Px) , and reduce Malondialdehyde ( MDA) content in brain homogenate in PSD in rats. CONCLUSIONS: TFA produces an antidepressant- like effect in PSD rats. This mechanism may be in association with attenuating hemorheological parameters and decreasing lipid peroxidative damage.

OBJECTIVE:To study the effect of the extracts of Paederia scandens (EPS) on acute gouty arthritis induced by monosodium urate in rats. METHODS: Monosodium urate crystals were used to establish gouty arthritis model in rats, with ankle joints' swelling degree at different time after modeling measured using paw volume measuring meter and gaits of rats scored at 24h after modeling. Pathological changes of articular tissues of rats were observed with HE staining and TNF-? and IL-1? levels were monitored by Radioimmunoassay. RESULTS:EPS could significantly inhibit joint swelling of rats and improve the gaits; histopathologically, EPS could abate tissue swelling of ankle joints, reduce inflammatory cell infiltration of articlar tissues and improve the pathological changes of synovial membranes. Radiommunoassay revealed that EPS could reduce levels of TNF-? and IL-1? in rats' synovial membranes. CONCLUSION:EPS have remarkable efficacy in improving symptoms of acute gouty arthritis induced by monosodium urate crystals in rats, which might be related to its inhibition on levels of IL-1? and TNF-?.
