Objective To investigate the changes and pathogenic significance of serum interleukin-12p70 (IL-12), intefferon-γ,(IFN-γ) and IL-4 in the course of hemorrhagic fever with renal syndrome(HFRS). Methods Twenty five eases were divided into mild group (14 eases) and severe group (11 cases) according to the severity of illness. Blood samples were collected in various stages(fever, hypotensian and oliguria,diuresis stage). Serum IL-12 and IFN-γ levels were determined by enzyme-linked immunoserbent assay(ELISA), IL-4 by radioimmunoassay (RIA), blood urea nitrogen (BUN) and platelet by automatic biochemical analyzer and blood analyzer. Results Serum IL-12 levels in mild and severe groups were significantly different during various stages of HFRS (F=5.765, P<0.01). The IL-12 level of both patient groups significantly increased(P<0.01) in fever[ (0.87±0.38), (1.08± 0.77)μg/L], hypotension and oliguria [ (0.77±0.21), (2.11±2.13)μg/L] ,and diuresis stage [ (1.42±1.10), (1.20±0.88)μg/L], compared with control group [(0.56±0.10)μg/L]. In various stages, IFN-γ levels of both case groups were respectively (8.04±13.05), (5.94±8.24), (15.95±18.05), (4.41±4.10), (1.09±1.24), (1.38±1.74), (1.12±1.26), (0.19±1.29)μg/L, and the difference was statistically significant compared with control [ (0.27±0.15)rig/L]. K,-4 levels did not change significantly in the stages(F=0.682, P0.05), while the ratios of IFN-γ and IL-4 contents in mild and severe cases were significantly higher than control [(0.36±0.26) μg/L] in fever[ (2.46±3.52), (16.92±22.77)p.g/L], hypotension and oliguria[(2.52±2.72), (1.77±2.06) μg/L],diuresis stage [(1.45±2.28), (2.32±3.98)μg/L], the difference had statically significant (P<0.05 or 0.01).The curve of IL-12 was similar to that of BUN, but was contrary to blood platelet count. Conclusions The elevated levels of IL-12 and IFN-γ, with the imbalance of Th1/Th2 might be the main cause of systemic inflammatoryresponse and involved in the pathogenesis of HFRS.

OBJECTIVETo compare therapeutic effects of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation in treating Tossy type III acromioclavicular joint dislocation.

METHODSForty-one patients with Tossy type III acromioclavicular dislocation treated by operation were retrospectively analysis from January 2012 to January 2014. The patients were divided into clavicular hook-plate fixation group (group A) and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation (group B) according to surgical procedures. In group A, there were 15 males and 6 females aged from 17 to 51 years old with an average of (31.60 ± 12.58) years old, preoperative Constant-Murley score was 40.25 ± 9.80, and treated with clavicular hook-plate fixation. In group B, there were 13 males and 7 females aged from 18 to 48 years old with an average of (29.40 ± 11.27) years old, preoperative Constant-Murley score was 41.45 ± 8.81, and treated with modified Weaver-Dunn surgery combined with clavicular hook-plate fixation. Operative time, blood loss, imaging changes before and after operation, postoperative complications were compared; Constant-Murley score at 3, 6 and 12 months after operation were evaluated.

RESULTSIn group A, operative time was 40.50 ± 24.36) min, blood loss was (75.30 ± 30.36) ml; In group B, operative time was (60.10 ± 23.55) min, blood loss was (100.70 ± 40.12) ml. Twenty-one patients in group A were followed-up from 12 to 18 months with an average of (14.8 ± 3.1) months; 20 patients in group B were followed-up from 12 to 14 months with an average of (13.6 ± 1.5) months. There were no significant differences in operative time, blood loss and follow-up time between two groups. Complications were in six patients of group A and 3 patients of group B, and there were no significant meaning between two groups. At 6 months after operation, Constant-Murley score in group A was 88.85 ± 4.23, 92.15 ± 3.82 in group B; and had significant meaning between two groups (t = -2.56, P = 0.022 < 0.05). While there were no differences in Constant-Murley score in other times.

CONCLUSIONBoth of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation are effective operative methods for the treatment of Tossy type III acromioclavicular dislocation. Clavicular hook-plate fixation has advantage of less trauma, while modified Weaver-Dunn surgery combined with clavicular hook-plate fixation could reconstruct coracoclavicular ligament more stronger, clavicular hook plate could take out earlier, also improve shoulder joint function earlier.

OBJECTIVETo explore the efficacy and the reproductive endocrinal mechanism of herbal-partitioned moxibustion in the treatment of primary dysmenorrhea.

METHODSOne hundred and seventy-one cases of primary dysmenorrhea were randomized into an herbal-partitioned moxibustion group (group A), an starch-partitioned moxibustion group (group B) and an acupuncture group (group C), 57 cases in each one. In the group A, moxibustion isolated with herbal medicine was applied to Shenque (CV 8). In the group B, moxibustion isolated with starch was used at Shenque (CV 8). In the group C, acupuncture was given at Sanyinjiao (SP 6). The changes of estradiol (E2), progesterone (P) and prostaglandin levels (PGF2alpha) were observed before and after treatment, and the therapeutic effects were compared among the 3 groups.

RESULTSThe therapeutic effect in the group A was better than those in the other two groups [compared the cured rate: 89.8% (44/49) vs 60.0% (30/50), 60.4% (32/53), both P < 0.05]. In the group A, E2 level [(110.99 +/- 12.90) pg/mL vs (83.94 +/- 8.91) pg/mL, P < 0.05] and PGF2alpha level [(24.58 +/- 3.01) pg/mL vs (14.34 +/- 1.48) pg/mL, P < 0.01] were decreased and P level was increased [(4.65 +/- 0.68) ng/mL vs (6.68 +/- 0.95) pg/mL, P < 0.05]. In the group B and C, PGF2alpha level were reduced. Concerning to the regulating of E2 and PGF2alpha levels, the results in the group A were better than those in the group B and C [(-30.16 +/- 10.20) pg/mL vs (10.79 +/- 15.01) pg/mL, (22.81 +/- 12.22) pg/mL; (-13.10 +/- 2.40) pg/mL vs (-6.52 +/- 1.88) pg/mL, (-3.14 +/- 1.19) pg/mL, (see text) P < 0.05]. Concerning to the regulation of P level, the results in the group A and B were better than that in the group C (all P < 0.05).

CONCLUSIONThe herbal-partitioned moxibustion achieves the significant efficacy on primary dysmenorrhea, which could be related to regulating the reproductive endocrinal level. It decreases E2 and PGF2alpha levels and increases P level.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.
