OBJECTIVETo investigate the long-term clinical effects of modified double Endobutton technique for the treatment of acromioclavicular joint dislocations of Tossy type III.

METHODSA retrospective study was done in 42 patients with acromioclavicular joint dislocations of Tossy type III treated with modified double Endobutton technique from December 2008 to December 2010. There were 24 males and 18 females, ranging in age from 21 to 56 years old (averaged, 32.5 years old). All the patients were treated with open reduction, coracoclavicular ligament reconstruction using double Endobutton technique, and repair of acromioclavicular ligament. The Karlsson system was used to evaluate therapeutic effects. The distance from coracoid to clavicle was measured to evaluate reduction loss.

RESULTSAll the patients were followed up, and the duration ranged from 2.0 to 3.2 years (averaged,2.4 years). According to Karlsson system, 32 patients got an A degree and 10 patients got a B degree at three months post-operatively; 26 patients got an A degree and 16 patients got a B degree at the latest follow-up; 6 patients got an A degree at 3 months after operation lowered to B degree at the latest follow-up. The coracoid-clavicle distance increased from (26.91 +/- 0.91) mm at 3 months after operation to (27.41 +/- 1.10) mm at the latest follow-up. Te patients treated with over-reduction during operation or with heavy physical labour work after operation had obvious widened coracoid-clavicle distance. Bone absorption was found around the plate in most cases, mainly in the clavicular side.

CONCLUSIONTreatment for acromioclavicular joint dislocations of Tossy type III with modified double Endobutton technique has satisfactory early clinical results. But with time passing, loss of reduction and bone absorption around the plate could be observed, and clinical outcomes of some cases downgrade during the long-term follow-up.

OBJECTIVETo explore the treatment of chronic calcaneal osteomyelitis with bone defect after debridement and evaluate its clinical outcomes.

METHODSFrom June 2009 to June 2011, 52 patients with chronic calcaneal osteomyelitis were treated with stage-one compound grafting of antibiotic-impregnated calcium sulfate and autogenous cancellous bone,including 12 females and 40 males with an average age of 43 years old ranging from 18 to 67. According to Cierny-Mader classification, there were 34 cases with stage III and 18 with stage IV. There were 32 cases on right side and 20 on left,with a course of 6 months to 3 years. The area of soft tissue wound ranged from 3.0 cm x l.5 cm to 23.0 cm x l2.0 cm. The clinical effects were evaluated according to infection controlling, calcium sulfate absorption,bone defect repair and heel functional recovery.

RESULTSAll patients were followed up for 2 to 3.8 years (averaged 2.8 years). Primary healing was achieved in 52 patients. Two cases of recurrence were found post-operatively, 1 case in 3 months and another in 5 months,which were cured after a second operation. Bone repair healing was gained in 1.5 to 3.5 months (averaged 2.5 months). Complete radiological absorption of calcium sulfate was found in 1.2 to 3 months(averaged 2.2 months). Local exudation after removal of drainage tube had been persisting in 10 patients for 2 to 3 months, which was consistent with the time when cacium sulfate were totally absorbed. Flap had partial necrosis in 4 cases,and the wounds were closed after appropriate treatment finally. The mean Maryland score was 88.15±7.70. There were excellent results in 32 cases, good in 14, fair in 6.

CONCLUSIONA satisfactory short-term clinical results can be gained by one-stage compound grafting of antibiotic-impregnated calcium sulfate and autogenous cancellous bone in chronic calcaneal osteomyelitis, but the long-term results need further follow-up. And much more study is also demanded to reduce the exudation of calcium sulfate.

Objective To study the relationship between erythromyein sensitivity and ermB gene in 143 Ureaplasma urealyticum (Uu) clinical isolates. Methods We detected the minimum inhabit concen-trations (MICs) of Uu to erythromycin by broth dilution method and MIC≥8 μg/ml was used as standard concentration of resistance to erythromycin. Polymerase chain reaction was used to detect the ermB gene and biotype Uu with primers based on multi-band antigen gene. Results The MICs, MIC50 MIC90 of Uu to erythromycin were ≤0. 125 μg/ml to ≥128 μg/ml, 16 μg/ml, and ≥128 μg/ml, respectively, with a high resistance rate of 64.38%. ermB gene, which was mainly detected in Uu with MIC≥8 μg/ml, was positively detected in 40 out of 143 Uu strains (27.97%). No significant differences of the resistance to erythromycin and positive rate of ermB gene were found between the two biovars in the study . Conclusion ermB gene may probably be one of the important genes conferring resistance to erythromycin in Uu. Further studies are needed to discover the difference of resistance and mechanism of erythromycin between the two bi-ovars.

OBJECTIVETo compare the effect and impact of holmium laser enucleation of the prostate (HoLEP) and 120-W thulium: YAG vapoenucleation of the prostate (ThuVEP) on erectile function in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe retrospectively analyzed 93 cases of symptomatic BPH treated by HoLEP or 120 W ThuVEP. We made comparisons between the two groups of patients in the baseline and postoperative clinical and surgical indexes as well as their IPSS, quality of life (QOL), maximum flow rate (Qmax), postvoid residual urine volume (PVR), and IIEF-EF scores before surgery and during the 12-month follow-up.

RESULTSThuVEP, in comparison with HoLEP, achieved a significantly shorter operation time ([57.6 +/- 12. 8] vs. [70.4 +/- 21.8] min, P = 0.001) and a higher laser efficiency ([0.71 +/- 0.18] vs. [0.62 +/- 0.19] g/min, P = 0. 021). At 1, 6, or 12 months of follow-up, no significant differences were observed in IPSS, OOL, Omax, and PVR between the two groups (P > 0.05). Both the HoLEP and ThuVEP groups showed low incidences of complications and remarkably improved IIEF-EF scores at 12 months postoperatively, but with no significant differences (both P > 0.05). However, in those with relatively normal erectile functions before operation, the mean IIEF-EF score was reduced from 22.8 +/- 2.2 preoperatively to 21.0 +/- 2.7 after HoLEP, (P = 0.036).

CONCLUSIONBoth HoLEP and 120W ThuVEP are effective and safe in the treatment of BPH. Compared with HoLEP, 120 W ThuVEP has even a higher laser efficiency. However, neither can significantly improve erectile function, and HoLEP may have a short-term negative impact on the relatively normal erectile function of the patient.

In the fast pace of modern life and under the heavy work pressure, the prevalence of depression has increased year by year. Meanwhile, the demands for antidepressant drugs have also grown, especially the high-efficiency and low-toxicity natural antidepressant drugs, mainly including polyphenols, flavonoids, organic acids, alkaloids and terpenoids. Cytochrome P450 (CYP450) is a type of enzymes involving oxidative metabolism of drugs in vivo, and can change the pharmacokinetics and efficacy of drugs. Therefore, it is of important significant to define the effect of natural antidepressant drugs on CYP450 in human bodies, in order to improve the rational clinical medication, avoid drug interactions and reduce adverse reactions.

OBJECTIVETo investigate the impact of hepatic steatosis on virologic response in chronic hepatitis B (CHB) patients treated with pegylated interferon-alpha (PEG-IFNa).

METHODSNinety-six naive patients positive for hepatitis B e antigen (HBeAg) and with biopsy-proven CHB were administered PEG-IFNa-2a or PEG-IFNa-2b for 48 weeks. Virologic response (HBeAg clearance and hepatitis B virus (HBV) DNA less than 5 log10 copies/ml) and biochemical response (alanine transaminase (ALT) normalization) were compared between patients with (n=34) and without (n=62) steatosis.

RESULTSThe HBV DNA titer in the steatosis group was significantly lower than that of the non-steatosis group (6.961.27 vs. 7.541.28 log10 copies/ml; t=2.161, P=0.033). After 48 weeks of PEG-IFNa treatments, there was no significant difference in HBeAg seroconversion or the percentage of undetectable HBV DNA (less than 3 log10 copies/ml) between steatosis and non-steatosis patients. However, the steatosis patients presented with a significantly lower complete response rate (virologic response plus biochemical response) compared to non-steatosis patients (26.5% vs. 48.4%; x² =4.373, P=0.037). Of the 45 CHB patients with undetectable HBV DNA after 48 weeks of treatment, seven did not achieve ALT normalization. The rate of patients with non-biochemical response was significantly higher in the steatosis group than in the non-steatosis group (33.3% vs. 6.67%; P=0.032).

CONCLUSIONHepatic steatosis does not affect the virologic response, but does affect the biochemical response in CHB patients treated with PEG-IFNa for 48 weeks.

This study is to offer a clinical pain-depression dyad therapy of ferulic acid, the pain-depression dyad induced by reserpine was established and the dose-effect relationship of ferulic acid on ameliorating pain-depression dyad was explored. Mice were randomly divided into control group, reserpine + vechile and reserpine + ferulic acid (5, 10, 20, 40 and 80 mg x kg(-1)) groups. The reserpine treated mice were tested with thermal hyperalgesia, mechanicial allodynia and forced swimming tests, and the SOD and NO levels of hippocampus and frontal cortex were measured. Moreover, the HPLC-ECD was used to detect the changes of central monoamines concentrations. Compared with control group, reserpine can induce a significant decrease in the nociceptive threshold and increase in the immobility time of the forced swimming test. The results suggested that reserpine significantly increased the level of nitrite in hippocampus and frontal cortex and reduced the levels of SOD, 5-HT and NE in these two brain regions. However, these indexes can be a dose-dependently reversed by ferulic acid (5, 10, 20, 40 and 80 mg x kg(-1)). Ferulic acid can reverse pain-depression dyad, especially at the dose of 80 mg x kg(-1). In addition, it can influence oxidative stress and monoamine level.
