OBJECTIVETo compare the efficacy differences between fire needling therapy and oxycycline tablets for the treatment of moderate to severe acne vulgaris.

METHODSSixty cases of moderate to severe acne vulgaris were randomly divided into a fire needling group and a medication group, 30 cases in each one. The pricking method of fire needling at Ashi points around damaged skin was applied in the fire needling group, once every five days for totally 4 times. The oral administration of oxycycline tablets, 100 mg, was applied in the medication group, twice daily for 20 days, also external application of adapalene gel before sleep was adopted. The fading time of skin damage, including papule, pustule, nodule and cyst in the two groups was recorded and clinical efficacy was compared. After the treatment, two-month follow-up was performed to observe the recurrence rate in the two groups.

RESULTSThe curative rate was 69.0% (20/29) in the fire needling group, which was statistically different from 40.0% (12/30) in the medication group (P < 0.05). The fading time of each type of skin damage in the fire needling group was shorter than that in the medication group [papule: (2.67 +/- 0.66) d vs (4.36 +/- 0.61) d; pustule: (2.47 +/- 0.57) d vs (4.27 +/- 0.55) d; nodule: (7.76 +/- 1.06) d vs (9.88-1.30) d; cyst: (11.81 +/- 1.54) d vs (14.79 +/- 0.89) d, all P < 0.05]. The recurrence rate was 46.4% (13/28) in the fire needling group, which was not significantly different from 44.0% (11/24) in the medication group (P > 0.05).

CONCLUSIONThe acne vulgaris could be fast and effectively treated by fire needling therapy, which has shorter fading time than oxycycline tablets. However, the preventive effect is not different between the two theraies.

Objective To observe the anesthesia and analgesia effect of ultrasound guided inter-scalene brachial plexus block (ISPSP)on upper extremity surgery.Methods Fifty-four patients (male 34 cases,female 20 cases,aged 37-73 years,ASA grade Ⅰ or Ⅱ)scheduled for elective upper limb surgery under ISPBP combined with general anesthesia were randomly assigned into two groups:magnesium sulfate group (group M,n =27)and control group (group N,n =27).0.5% ropivacaine 8ml (40 mg)+10% magnesium sulfate 2 ml (0.5 g)were used in group M ,0.5% ropivacaine 8 ml+ normal saline 2ml (40 mg)were used in group N.After the effects of ISBPB were confirmed,pa-tients were inserted laryngeal mask under intravenous induction.Anesthesia was maintained by inha-ling sevoflurane(MAC 0.8)during the operation.The onset time of sensory and motor block,duration of sensory and motor block,duration of analgesia,pain visual analogue digital score (VAS)4,8,12, 24 hours after operationand complications were recorded.Results Duration of sensory block and du-ration of analgesia of group M was significantly longer than those of group N (P <0.05).The patient`s VAS score of 8,12,24 hours after surgery in group M was significantly lower than that on group N (P <0.05).Onset time of sensory and motory block of both groups was similar.Conclusion 0.5%ropivacaine combined with magnesium sulfate in ultrasound-guided ISPBP can extend the duration of sensory block,reduce postoperative pain,as well as prolong analgesia time.

OBJECTIVETo investigate the effects of total flavonoids of propolis (TFP) on apoptosis of myocardial cells of chronic heart failure and its possible mechanism in rats.

METHODSSix male SD rats were randomly selected as normal control group, the remaining rats were made as chronic heart failure (CHF) model by intraperitoneal injection of adriamycin. The rats in the successful model were randomly divided into five groups (n = 6): CHF group, total flavonoids of propolis low dose group (LD group), total flavonoids of propolis middle dose group (MD group), total flavonoids of propolis high dose group (HD group), digoxin group (DIG group). After six week treatment, cardiac function indexes of rats were recorded by signal acquisition system; brain natriuretic peptide (BNP), cardiac troponin I (cTnI), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) content in plasma were detected; Myocardial morphological changes and collagen fiber hyperplasia by HE and Masson staining were observed; Myocardial apoptosis was detected with TUNEL method and protein connexin 43(P-Cx43) expression was detected by Western blot method.

RESULTSCompared with NC group, left ventricular systolic pressure(LVSP) and maximal rise/fall velocity of left ventriculad pressure (± dP/dt(max)) absolute value in CHF group were significantly lowered (P < 0.01) while left ventricular end diastolic pressure (LVEDP) was increased significantly (P < 0.01); Contents of plasma BNP, cTnI, TNF-α and IL-6 in the CHF group were significantly improved (P < 0.01). Compared with CHF group, LVSP, ± dP/dt(max) absolute value in MD and HD groups were increased (P < 0.05), and LVEDP was significantly lowered (P < 0.01); LVEDP in LD group was significantly lowered (P < 0.01), changes in LVSP and ± dp/dt(max) absolue value were not obvious (P > 0.05). BNP, cTnI, TNF-α and IL-6 contents in MD and HD groups were significantly reduced (P < 0.01), but those plasma indicator changes were not obvious in LD group (P > 0.05). Western blot showed that P-Cx43 expression in CHF group was significantly higher than that in NC group (P < 0.01) and that in all TFP treatment groups it was decreased compared with CHF group (P < 0.05, P < 0.01), among which pairwise comparisons also showed differences (P < 0.05), myocardial apoptosis index (%)(22.62 ± 3.39) in CHF group was higher than that in NC group( 1.12 ± 0.24) (P < 0.01); compared with CHF group, the apoptosis index of myocardial cells (%) in LD,MD and HD groups, (15.79 + 2.8), (9.28 + 2.1) and (4.73 + 1.14) respectively, were significantly lower than those in the CHF group( P < 0.01). The expression level of P-Cx43 positively correlated with the apoptotic index (r = 0. 861, P < 0.01).

CONCLUSIONTotal flavonaids of propolis have inhibitory effect on apoptosis of myocardial cells of chronic heart failure induced by adriamycin in rats, and the mechanism may be closely related to the regulation of Cx43 expression, especially the regulatory phosphorylation status.

OBJECTIVE: To investigate the effect of androgen on nitric oxide synthase activity and kidney function in the kidney of rats with ischemic injury. METHODS: Fourty-eight adult healthy male SD rats were randomly divided into the renal ischemia group (n = 24 ) and the orchidectomized group with renal ischemia (n = 24). The two groups were randomly divided into 4 groups by the survival time: 0, 1, 3 and 7 days. NADPH diaphorase histochemistry was used to measure the nitric oxide synthase activity of the kidney with ischemic injury in the orchidectomized group and the control group. The image analysis technology system was used to quantify the NOS. BUN and BCr in the plasma were detected when the rats were executed. RESULTS: The NOS histochemical staining of the kidney was mainly distributed in the renal tubule, macula densa and low in the renal glomerular. The NOS activity of macula densa significantly decreased in the orchidectomized group compared with that in the control group (P < 0.05) . BUN and Bcr have no significant difference on 0, 1 and 7 days (P > 0.05) , but on the third day the data markedly increased (P < 0.05). CONCLUSION Androgen can adjust the blood flux of glomerular by regulating the NOS activity of macula densa, and affect the kidney function.
