[Excision of necrotic and infected tissues combined with induced membrane and external fixator technique for the treatment of chronic osteomyelitis in tibia after fracture operation].

OBJECTIVE: To investigate the clinical efficacy of excision of necrotic and infected tissues combined with induced membrane and external fixator technique to treat chronic osteomyelitis in tibia after fracture operation. METHODS: From June 2011 to June 2014, a total of 13 patients with tibia osteomyelitis were treated with excision of necrotic and infected tissues and external fixator technique in the first stage. There were 8 males and 5 females, ranging in age from 16 to 67 years old with an average of (37.3±14.3) years old. Within 6 to 8 weeks the induced membrane was formed and the induced membrane technique was applied to promote new bone forming in the second stage. RESULTS: Thirteen patients had no reinfection and achieved complete bone healing after 24 to 52 months follow-up. All the patients had satisfactory function. CONCLUSIONS: Excision of necrotic and infected tissues combined with induced membrane and external fixator technique to treat chronic osteomyelitis in tibia after fracture operation can provide satisfactory results.

Efficacy and safety of Wuling capsule, a single herbal formula, in Chinese subjects with insomnia: a multicenter, randomized, double-blind, placebo-controlled trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Wuling Capsule is a single herbal formula from mycelia of precious Xylaria nigripes (Kl.) Sacc and its pharmacological function have a tranquilizing effect on the central nervous system. The aim of the study to evaluate the efficacy and safety of Wuling capsule in treatment of insomnia. MATERIALS AND METHODS: We performed a multicenter, randomized, double-blind, placebo-controlled study. The participants received either placebo (n=92) or Wuling capsule (n=94) for 4 weeks and a follow-up period for 2 weeks. RESULTS: Compared between pre-treatment and post-treatment, the global Pittsburgh sleep quality index (PSQI) scores in both Wuling capsule group and placebo group improved significantly (P<0.01). However, there was no significant difference between Wuling capsule group and placebo group (P>0.05). Scores of clinical global impressions scale (CGI-I) at each week in Wuling capsule group was similar to those in placebo group (P>0.05). Compared between pre-treatment and post-treatment, scores of the four components of world health organization on quality of life brief scale (WHOQOL-BREF) in both Wuling capsule group and placebo group improved significantly (P<0.01). However, there were no difference between the two groups (P>0.05). The rate of adverse events was 10.10% in Wuling group, and 6.73% in placebo group (P>0.05). CONCLUSIONS: Wuling capsule can improve insomnia when compared with pre-treatment for 4 weeks and be a well tolerated by all the patients at the 6 weeks of study period. However, there are no significant in the results of the variables tested when compared with placebo control. Further additional rigorous randomized clinical trials are still required.

[Analysis of symptom compositions in sub-health insomnia patients of Yin deficiency fire hyperactivity syndrome and Xin-Pi deficiency syndrome].

OBJECTIVE: To study Chinese medicine syndrome features in sub-health insomnia patients, and to make clear the symptom compositions of each syndrome, thus providing references for main and minor symptoms selection, and establishing a syndrome differentiation system in clinical testing. METHODS: Chinese medicine syndrome information was collected by multi-centered large-sample clinical data. The information was statistically managed to get common syndrome types, symptoms compositions, and the Pittsburgh Sleep Quality Index (PSQI) scores of sub-health insomnia patients. RESULTS: The most common symptoms of sub-health insomnia patients of yin deficiency fire hyperactivity syndrome and Xin-Pi deficiency syndrome cover difficulties in falling asleep, early awakening, dreaminess, sometimes sleeping sometimes awake, failing in falling into sleep when wake up, failing in sleep all night. There was insignificant difference between the two syndrome types (P>0.05). Some unique symptoms occurred in the two syndrome types as minor symptoms. Fatigue, abdominal distension after eating occurred in patients of Xin-Pi deficiency syndrome. Burning sensation of five centers, irritability, etc. occurred in patients of yin deficiency fire hyperactivity syndrome. Significant difference was shown in minor symptoms (except irritability, vexation, frequent urine) (P<0.05, P<0.01). No significant difference was shown in PSQI score between the two syndrome types (P>0.05). But significant difference was shown in sleep disturbance factors (P<0.05). Patients of yin deficiency fire hyperactivity syndrome had severe sleep disturbance factors. CONCLUSION: There was no significant difference in main symptoms between the two syndrome types. Some unique symptoms occurred in the two syndrome types as minor symptoms. There was difference in sleep quality compositions.
