BACKGROUND: As the first long-acting atypical antipsychotics, the therapeutic effect and safety of risperidone microsphere have been proved. However, it may lead to serious pain due to the deep intramuscular injection.OBJECTIVE: To evaluate the pain levels by 12-week injection of rispeddone microsphere and to explore the relationship among dose and times of injection of risperidone microsphere and pain levels.METHODS: A total of 57 patients diagnosed as schizoprenia by DSM-Ⅳ, aged 18-65 years, were selected and injected risperidone microsphere once every 2 weeks with doses of 25, 37.5 and 50 mg. The pain levels were evaluated using 100 mm visual analogue scale during injection and at the injected sites. The effects of injected dose, injected frequency and injected sites on the pain were analyzed by the nurse questionnaire.RESULTS AND CONCLUSION: The pain levels among the different doses groups had no notable differences (F=1.35,P> 0.05), which demonstrated that the pain had no relationship with injected dose. However, the pain level of injected sites had correlation to injected doses. The pain level of the 50 mg group was greater than that of the 37.5 and 25 mg groups. Accordingly,patients who treated by high dose of risperidone microsphere should be intervened by nurses.

Objective To investigate the optimum target plasma concentration of propofol in preventing the adverse effects of carboprost tromethamine in the patients undergoing caesarean section.Methods One hundred and twenty-eight nulliparous parturients who were at full term with a singleton fetus,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 24-37 yr,weighing 54-78kg,scheduled for elective caesarean section under combined spinal-epidural anesthesia,were randomly divided into 4 groups (n =32 each) using a random number table:control group (group C),and different concentrations of propofol groups (P1-3 groups).Carboprost tromethamine 250 μg was injected into the body of the uterus,and propofol with the target plasma concentrations of 0.8,1.2 and 1.6 μg/ml was simultaneously given by target-controlled infusion in P1,P2 and P3 groups,respectively,and normal saline was infused at a rate of 0.5 ml · kg-1 · h-1 in group C.The occurrence of cardiovascular events was recorded from the end of carboprost tromethamine administration until the end of surgery.The relatedadverse effects after carboprost tromethamine administration,and Ramsay sedation score at 15 mm after carboprost tromethamine administration were recorded,and satisfactory sedation was defined as Ramsay sedation score of 2.The occurrence of complications associated with combined spinal-epidural anesthesia was recorded during the postoperative follow-up.Results Compared with group C,the incidence of carboprost tromethamine-related adverse effects was significantly decreased in P2 and P3 groups,the rate of satisfactory sedation was significantly increased in P1 and P2 groups,the incidence of hypotension and tachycardia was significantly decreased in group P1 (P＜0.05),and no significant change was found in the incidence of carboprost tromethamine-related adv erse effects in group P1,and in the rate of satisfactory sedation in group P3 (P＞ 0.05).Compared with group P1,the incidence of carboprost tromethaminerelated adverse effects was significantly decreased in P2 and P3 groups,the rate of satisfactory sedation was significantly increased in group P2,and the rate of satisfactory sedation was significantly decreased in group P3 (P＜0.05).Compared with group P2,the rate of satisfactory sedation was significantly decreased (P＜0.05),and no significant change was found in the incidence of carboprost tromethamine-related adverse effects in group P3 (P＞0.05).No cardiovascular events were found in group P2,and the incidence of hypotension was 9％ in group P3.Conclusion The optimum target plasma concentration of propofol in preventing the adverse effects of carboprost tromethamine is 1.2 μg/ml in the patients undergoing caesarean section.

Objective To investigate the effect of periurethral injection of insulin-like growth factor(IGF)-Ⅰ on the expression of IGF-Ⅰ and IGF-Ⅱ mRNA during regeneration period following urethral sphincter muscle injury in female rats. Methods Model of urethral sphincter muscle injury was made in female virgin SD rats (n=50) by intravaginal balloon inflation. Then the rats were divid-ed randomly into treatment group (n= 25) and control group (n= 25), treatment group accepted peri-urethral injection of 1.0μg human IGF-Ⅱ to the middle urethral muscle, control group accepted nor-mal saline injection. Five rats in each group were sacrificed at 2, 4, 6, 8, 14 day respectively and the whole urethra specimens were processed for RT-PCR to detect the expression of IGF-Ⅰ ,Ⅱ mRNA. A normal control group (n = 5) was set without intravaginal balloon inflation and injection. Results The expression of IGF-Ⅰ mRNA in control group increased at day 4, 6, 8, 14, the IGF-Ⅰ/β-actin ra-tios were 0. 58±0.15, 1.73±0.31, 2.30±0.29, 0. 46±0. 06. The expression of IGF-Ⅰ mRNA in treatment group increased at all time points, as 0. 69±0.21, 1.45±0.17, 2.25±0.45, 2.90±0.49, 1.92±0. 31. The difference was significant on day 4, 14(P<0.01), and day 8 (P<0.05) compared with the control group. The expression of IGF-Ⅱ mRNA in control group increased at day 4, 6, 8, as 0.42±0. 14, 1.51±0. 59, 1.31±1.04. The expression of IGF-Ⅱ mRNA in treatment group in-creased at day 4, 6, 8, 14, as 1.04±0.23, 1.94±0.29, 1.75±0.41, 0. 81±0.15. The significant difference was noted on day 4 (P<0. 01)compared with the control group. No expression of IGF-Ⅰand Ⅱ mRNA in the normal control group. Conclusions The expression of endogenous IGF-Ⅰ and IGF-Ⅱ mRNA was up-regulated by periurethral injection of IGF-Ⅰ during regeneration period follow-ing urethral sphincter muscle injury in female rat. Our findings suggest that IGF-Ⅰ facilitates the re-generation of the urethral muscles and may play a role in treatment of stress urinary incontinence in-duced by urethral sphincter muscle dysfunction.

Objective To investigate the P2X3 receptor expression in L6-S1 dorsal root ganglion (DRG)and bladder detrusor in a rat model of neurogenic bladder and urethra. Methods Eighty Sprague-Dawley rats wererecruited and randomly divided into a sacral injury group, a suprasacral injury group and a control group. Spinal tran-section was performed to establish the animal model of neurogenic bladder and urethra in rats of the sacral injurygroup and suprasacral injury group. Check the P2X3 receptor expression in DBG and bladder detrusor among thethree groups by Western blot test at 20 days after model establishment. Results P2X3 receptor expression in L6-S1DRG of sacral injury group was significantly less than that of the suprasacral injury group, which was in turn signifi-cantly higher than that of the control group. P2X3 receptor expression in bladder detrusor of sacral injury group wassignificantly lower than that of the suprasacral injury group, which was in turn significantly higher than that of thecontrol group. Conclusion There was close relationship between P2X3 receptor expression and dysfunction of blad-der and urethra.

OBJECTIVETo investigate the guidance role of preoperative nutritional risk screening in perioperative nutrition support for colorectal cancer patients in order to provide evidence for the rational clinical application of nutrition support.

METHODSNutritional risk screening was carried out in 290 hospitalized colorectal cancer patients from The Fourth People's Hospital of Wuxi City, Tongji Hospital of Tongji University and The Second Hospital of Soochow University with the nutritional risk screening(NSR) 2002 score summary table. Postoperative bowel function recovery and associated nutritional indices were compared between patients who received preoperative nutrition support according to the risk screening results and those who did not.

RESULTSAmong 110 patients at nutritional risk, 65 received perioperative nutrition support and had faster recovery of intestinal function [time to first flatus (2.3±0.5) d vs. (3.3±0.5) d, time to first defecation (3.5±0.5) d vs. (4.6±0.6) d, semi-fluid intake (10.1±1.2) d vs. (12.4±2.2) d], shorter postoperative stay [(15.7±1.1) d vs. (18.8±1.4) d], and higher albumin, prealbumin and transferrin [(33.2±4.5) g/L vs. (26.0±4.0) g/L, (0.28±0.05) g/L vs. (0.16±0.04) g/L, (1.92±0.33) g/L vs. (1.75±0.45) g/L] at 7-day postoperatively (all P<0.05) as compared to those without perioperative nutrition support(n=45). While among 180 cases without nutritional risk, there were no significant differences in the above indices between patients who received preoperative nutrition support and those who did not (all P>0.05).

CONCLUSIONIt is important to evaluate the nutritional risk in hospitalized patients with colorectal cancer, and to carry out nutrition support actively for those at nutritional risk.
