Objective To inquire clinical effects of hysteroscopic electroresection in the treatment of submucous hysteromyoma. Methods A retrospective analysis regarding curative effects of hysteroscopic electroresection in 72 cases of submucous hysteromyoma was carried out. Results The resected myoma was 1.5~7 cm in diameter, and the number of resected myoma was 1~3. The operation time was 10~90 min (mean, 30 min). The operation was accomplished on one session in all the 72 cases. No uterine perforation, bleeding and bowel injuries took place. Postoperative follow-up for 4~20 months in the 72 cases reported a satisfaction rate of 97 2% (70/72). Out of 6 patients who had pregnancy desire, 2 were pregnant with child and 1 of them had a delivery. Conclusions Hysteroscopic electroresection in the treatment of submucous hysteromyoma is safe and effective. It can markedly improve the menstruation and elevate the pregnancy rate.

Objective To build a simulation model for outpatients queuing,using data from a general outpatient cardiovascular clinic of a general hospital in Shanghai and different rules in the process.The study employs time-interval controlled mode for appointment registration,for the purpose of analyzing characteristics of different queues.Methods Extraction of data of the clinic in a given month by means of HIS system to determine the parameters of the queuing models.Building the simulation model with Matlab to develop the plan of mixed queues and that of discrete queues,for analyzing the waiting time variations,with different number of doctors on duty and different number of appointments in one time interval.Resnlts In the Monday mornings for example,the mean waiting time of appointments or no-appointments are calculated by simulation with different queuing rules,different number of doctors on duty and different appointment quantities of one time interval.Conclusion The mean waiting times of appointments and no-appointments can be both sizably cut short by means of time-interval controlled appointment; different queuing plans are recommended for different departments; the simulation model should be further verified and optimized in practice.

Objective To observe the influence of tumor necrosis factor-alpha(TNFα) on skeletal muscle protein catabolism in rats with chronic obstructive pulmonary disease (COPD) and the effects of indomethacin (IND) on it. Methods Duplicated COPD model rats were divided into two groups: the malnutrition group and the normal nutrition group. The malnutrition group were further divided by randomized block design into four groups. Isotonic physiologic saline was administered to group A, the control and the normal nutrition group, and different doses of oral IND were administered to groups B, C, and D weight, concentrations of TNFα, contents of 3-methyl-histidine ( 3- M H ) and tyrosine (Tyr) in the diaphragm and extensor digitorum longus muscle homogenates were measured before and after the intervention. Results Before the intervention, the concentrations of TNFα in the serum of malnutrition groups were all significantly higher than those of normal nutrition group and the control group. After the intervention: (1) The concentrations of TNFα in the serum of the rats of group B, C and D were significantly lower than the group A, especially in group C. The levels of TNFα in serum and body weight of model group rats were negatively correlated ( r = -0. 846, P ＜0. 01 ), as well as the diaphragm and extensor digitorum longus muscle weights ( r = - 0. 778, P ＜ 0. 01; r = - 0. 772, P ＜ 0. 01 ). (2) The levels of 3-methyl-histidine in the diaphragm and extensor digitorum longus muscles of the intervention group C was lower than the COPD normal nutrition group, as well as the intervention groups B and D. The contents of tyrosine in the diaphragm and extensor digitorum longus muscles of the intervention group C was lower than that of the COPD normal nutrition group,as well as the groups B and D. The body weight growth value of the intervention group B were slightly higher than the group A, without significant difference( P ＞ 0. 05 ), while the group C was significantly higher than the group A ( P ＜ 0. 01 ). Conclusions TNFα is involved in the occurrence of COPD malnutrition and skeletal muscle amyotrophy. IND can reduce the TNFα levels in the serum and the catabolic rates of the skeletal muscle proteins in malnutrition rats with COPD, so as to improve partly the skeletal muscle atrophy.

Abstract? AIM: Through the establishment of penetrating keratoplasty model of rats, to detect the role and its mechanism of immature dendritic cells with IL-10 gene modified.? METHODS: Allogeneic penetrating corneal transplantation in rat model was performed. SD rats were randomly divided into positive control group, GFP-DC group, 8-DC and IL-10-GFP-DC group.At 3d before keratoplasty, the rats were given tail intravenous injection with the same amount of PBS, bone marrow 8-DC ( DC had cultured for 8d ) from donor Wistar rats, GFP-DC after 48h transfection and IL-10-GFP-DC.Rats were observed under slit-lamp for corneal graft cases every day, and recorded rejection index and corneal graft survival time.At 14d after keratoplasty, pathologic and immunohistochemical examinations were performed.?RESULTS:Compared with GFP-DC group and 8-DC group, corneal graft survival time of IL-10-GFP-DC group was significantly longer ( P<0.01 ); at 14d after keratoplasty, corneal opacity, edema, neovascularization and rejection index of IL-10 -GFP-DC group were significantly lower (P<0.01).Pathological examination showed that in the three experimental groups corneal inflammation was lighter than the positive control group without significant central graft neovascularization. Immunohistochemistry showed: compared to the positive control group, GFP-DC group and 8-DC group, CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cells in IL-10-GFP-DC group were lower(P<0.01).? CONCLUSION: After donor -derived immature dendritic cells pretreated, corneal graft survival was significantly prolonged, successfully induced corneal transplantation tolerance. CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cells are involved in corneal allograft rejection regulation, IL-10-GFP-DC may reduce CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cell infiltration, inhibit corneal transplant rejection.

?AlM: To investigate the clinical characteristics and influencing factors of chronic renal failure ( CRF) patients with dry eye, and to provide clinical reference.?METHODS:Sixty-one cases (122 eyes) of patients with CRF ( CRF group ) and 61 cases ( 122 eyes ) of healthy persons ( control group) were carried out on Schirmer ▏test ( S▏t ) , break-up time of tear film ( BUT ) , corneal fluorescein staining ( FL) , test results of two groups were compared and related factors of dry eye in CRF patients were analyzed.?RESULTS: The results of S▏t and BUT in CRF group were lower than that in the control group (P<0. 05). The proportion of tear secretion reduce in CRF group ( S▏t<10mm/5min) was 49. 2% ( 60/122 ), which was higher than that in the control group ( 10. 0%, 12/122 ), the difference was statistically significant ( X2 = 45. 39, P <0. 05). The percentage of instability of tear film in CRF group (BUT≤10s) was 75. 4% (92/122), which was significantly higher than that in the control group (27. 0%, 33/122) (X2=57. 1, P<0. 05). The positive rate of corneal FL was 37. 7% (46/122), which was higher than that of the control group (10. 7%, 13/122), there was a statistically significant difference (X2= 24. 34, P<0. 05).?CONCLUSlON:CRF patients with a decrease in tear film stability and tear secretion are susceptible population to dry eye, clinically should be paid attention to the treatment.

Clinical features and thyroid-stimulating antibody(TSAb)in 32 newly diagnosed patients with Graves' ophthalmopathy(GO)were compared with those in 27 Graves' disease(GD)patients without GO(as control group).All of the patients with GO received intravenous glucocorticoids.The level of serum TSAb in patients with GO was significantly higher than that in patients without GO.TSAb was also associated with the prognosis.It suggests that TSAb seems to be the most active component among the TSH receptor antibodies related to ophthalmopathy and may act as a predictive parameter.
