OBJECTIVE To remove the bad effect of the supply voltage on the ultraviolet ray disinfection and using the intelligent controller to solve the problem of supply voltage on the ultraviolet intensity of the ultraviolet lamp.METHODS The method was to find the relationship between the voltage and disinfection time,use the intelligent controller to detect the supply voltage and use the computation to control the disinfection time,and then revise the disinfection time according to the variation of the voltage in time.RESULTS The method could compensate the bad effect of the variation of the supply voltage on the ultraviolet and can control the ultraviolet disinfection automatically.CONCLUSIONS That means this method has a good application in future.

Objective To evaluate the clinical efficacy of compound Sophorae Flavescentis Radix (Kushen) injection intravenous drip combining carboplatin intraperitoneal injection in treating advanced ovarian cancer with malignant ascites. Methods Totally 160 patients with advanced ovarian cancer with malignant ascites were randomly divided into compound Kushen injection intravenous drip combining carboplatin intraperitoneal injection group (observation group) and carboplatin intraperitoneal injection group (control group). Clinical efficacy observation and evaluation were conducted from malignant ascites condition, changes in living quality (KPS score), T lymphocytes subsets and changes of the NK cells in blood samples, pain-relieving efficacy, and toxicity response. Results There were significant differences in malignant ascites between the two groups (P<0.05), with treatment group showing better improvement than the control group. In improving quality of life, the observation group had precedence over the control group (P<0.01). After treatment, CD3+, CD4+, CD4+/CD8+, NK (CD16+CD56+) in control group were obviously less than the observation group (P<0.05). The pain-relieving efficacy in the observation group was superior to that in the control group. Compared with the control group, the observation group had less gastrointestinal reaction and bone marrow suppression, with statistical significance (P<0.05). Conclusion Compound Kushen injection intravenous drip combined with carboplatin intraperitoneal injection in treating advanced ovarian cancer with malignant ascites can effectively improve the immune function and quality of life, and can be used for adjuvant chemotherapy with less side effects.

Objective To observe the effects of combined use of PGE1 with benazepril on the treatment of early diabetic nephropathy.Methods 63 patients with early diabetic nephropathy were divided randomly into the combination treatment group with benazepril daily and PGE1 10?g daily for 14d,and the benazepril group with benazepril daily.Results Compared with the benazepril group,proteinuria and albuminuria significantly decreased in the combination treatment group from 2 weeks' therapy to 6 months after the therapy (P

Objective To investigate the role of glycogen synthase kinase-3β (GSK-3β) in the trafficking of NR1-containing N-methyl-D-aspartate receptor (NMDAR) and NR2B-containing NMDAR in the spinal cord in rats with incisional pain (IP) and remifentanil-induced hyperalgesia.Methods Twenty-four male Sprague-Dawley rats,aged 2-3 months,weighing 240-260 g,were randomly divided into 3 groups ( n =8 each):control group (group C),remifentanil group (group R) and GSK-3β inhibitor TDZD-8 group (group TDZD-8).A 1-cm longitudinal incision was made in the plantar surface of the left hindpaw in anesthetized rats.In group C,dimethyl sulfoxide (DMSO) 2 ml/kg was injected and then the normal saline (equal to the volume of remifentanil) was infused for 60 min via the caudal vein.In group R,DMSO 2 ml/kg was injected before IP was made and then remifentanil was infused at a rate of 1.2 μg· kg- 1 ·min- 1 for 60 min.In group TDZD-8,TDZD-8 2 ml/kg was injected before IP was made and then remifentanil was infused at a rate of 1.2 μg·kg-1 ·min-1 for 60 min.Paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) were measured 24 h before infusion of normal saline or remifentanil and at 2,6,24 and 48 h after intravenous injection.The rats were sacrificed after the last measurement of the pain threshold and L4-6 segment of the spinal cord was removed to determine the expression of NMDAR NR1 and NR2B subunits in cell membrane (s) and cytoplasm (i) in the spinal cord by Western blot analysis.The ratios of sNR1/iNR1 and sNR2B/iNR2B were calculated.Results Compared with group C,PWT was significantly decreased and PWL was significantly shortened,the expression of sNR1 and sNR2B was up-regulated,the expression of iNR1 and iNR2B was down-regulated,and the ratios of sNR1/iNR1 and sNR2B/iNR2B were significantly increased in groups R and TDZD-8 (P ＜ 0.05).Compared with group R,PWT was significantly increased and PWL was significantly prolonged,the expression of sNR1 and sNR2B was down-regulated,the expression of iNR1 and iNR2B was up-regulated,and the ratios of sNR1/iNR1 and sNR2B/iNR2B were significantly decreased in group TDZD-8 ( P ＜ 0.05).Conclusion GSK-3β is involved in the regulation of trafficking of NR1-containing NMDAR and NR2B-containing NMDAR from cytoplasm to cell membrane in the spinal cord in rats with IP and hyperalgesia induced by remifentanil.
