OBJECTIVETo explore the therapeutic effects of amiodarone and metoprolol, either alone or in combination, on chronic heart failure (CHF) complicated by ventricular arrhythmia.

METHODSA total of 110 NYHA class II-III patients with CHF complicated by ventricular arrhythmia were randomly divided into amiodarone group, metoprolol group and amiodarone + metoprolol group. The therapeutic effects was evaluated at the end of the 1-year follow-up.

RESULTSAmiodarone, metoprolol and their combination produced statistically different therapeutic effects (P<0.05). Compared with amiodarone and metoprolol used alone, amiodarone combined with metoprolol resulted in significant cardiac function improvement (P<0.05) and ventricular arrhythmia control (P<0.01). During the 1-year follow-up, the readmission rate and cardiac event rate in the amiodarone + metoprolol group were significantly lower than those in amiodarone group (P<0.01) and metoprolol group (P<0.05). The adverse reaction rates in the 3 groups were similar (P>0.05).

CONCLUSIONThe combination of amiodarone and metoprolol produces better effect than amiodarone or metoprolol alone in the treatment of CHF complicated by ventricular arrhythmia.

OBJECTIVETo investigate the spectrum of pathogens for community-acquired pneumonia (CAP) in children, and to provide a basis for the diagnosis and treatment of CAP.

METHODSRespiratory secretions and venous blood samples were collected from 1560 children with CAP aged from one month to 9 years within 2 hours after admission, for detection of multiple pathogens. Respiratory virus antigens in nasopharyngeal swab specimens were detected by immunofluorescence. Sputum was used for bacterial culture. Levels of Mycoplasma pneumoniae (MP)-IgM and Chlamydia pneumoniae (CP)-IgM in venous blood were measured by enzyme-linked immunosorbent assay.

RESULTSA total of 579 strains of bacteria were isolated from all respiratory secretions, including 213 (36.8%) Gram-positive strains and 366 (63.2%) Gram-negative strains. The five most common strains were Haemophilus influenzae (7.50%), Streptococcus pneumoniae (6.73%), Staphylococcus aureus (6.35%), Moraxella catarrhalis (5.19%), and Escherichia coli (3.46%), wherein the beta-lactamase-producing strains accounted for 3.3% of all strains. The non-bacterial pathogens mainly included respiratory syncytial virus (12.88%), MP (7.88%), and CP (8.91%). Mixed infection of pathogens was serious, and the mixed infection of respiratory syncytial virus with Haemophilus influenzae infections were the most common. For most pathogens, the infection rate was higher in children aged under one year than in those aged over one year.

CONCLUSIONSHaemophilus influenzae, respiratory syncytial virus, MP and CP are the main pathogens for children with CAP. For most pathogens, the infection rate is higher in children aged under one year than in those aged over one year. Mixed infection rate of pathogens is high.

OBJECTIVESTo compare the outcomes after liver resection for a single small hepatocellular carcinoma (HCC) (≤ 5 cm) between non-cirrhotic patients and cirrhotic patients, and to explore the influence of liver cirrhosis on recurrence and overall survival after liver resection in patients with a single small HCC.

METHODSA consecutive series of 256 patients with a single small HCC undergoing liver resection from April 2001 to October 2009 was retrospectively reviewed. Among the 256 patients, 227 patients were male, and 29 were female. The medium age was 49 years (ranged, 14 - 79 years); 224 (87.5%) patients were positive for hepatitis B surface antigen, 241 (94.1%) patients were with preoperative liver function of Child-Pugh grade A. The entire cohort were divided into non-cirrhosis group (n = 44) and cirrhosis group (n = 212). Univariate analysis and then multivariate analysis were performed to determine the prognostic factors of recurrence and overall survival after liver resection for all patients.

RESULTSThe 1-, 3-, 5-year recurrence-free survival rates after liver resection were 93.0%, 85.3%, and 68.5%, respectively, in non-cirrhosis group, while 81.1%, 58.6%, and 45.0%, respectively, in cirrhosis group. The 1-, 3-, 5-year overall survival rates after liver resection were 100%, 92.5%, and 92.5%, respectively, in non-cirrhosis group, while 93.8%, 78.7%, and 67.8%, respectively, in cirrhosis group. Both the recurrence-free survival and overall survival of non-cirrhosis group were significantly better than those of cirrhosis group (χ(2) = 8.756, P = 0.003; χ(2) = 8.603, P = 0.003). Cirrhosis, absence of tumor capsule, presence of microvascular invasion and moderate/poor tumor differentiation were the independent adverse prognostic factors for recurrence-free survival and overall survival in patients with a single small HCC after liver resection.

CONCLUSIONSCirrhosis is an important adverse prognostic factor for long-term survival in patients with a single small HCC after liver resection. Liver resection resulted in much worse survival for cirrhotic patients compared to non-cirrhotic patients.

BACKGROUND: Adiponectin is one of the adipocytokines that have been found to be negatively correlated with obesity in recent years. As an endogenous bioactive peptide, adiponectin is shown to be associated with insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and participate in the regulation of bone metabolism. OBJECTIVE: To describe the mechanism of adiponectin in bone metabolism, and mainly clarify the correlation of adiponectin with osteoblasts and osteoclasts. METHODS: The first author searched PubMed and CNKI databases for the articles addressing the experimental research and research progress of adiponectin in bone metabolism published from 2003 to 2017. The keywords were "adiponectin, osteoporosis, bone metabolism, osteogensis, bone absorption" in English and Chinese, respectively. Adiponectin, its receptors, bone metabolism, adiponectin effects on bone formation and bone resorption were reviewed. RESULTS AND CONCLUSION: Adiponectin exerts a comprehensive effect on bone metabolism, mainly through autocrine, paracrine and endocrine, insulin signaling pathways. Besides, it exerts biological effects mostly by regulating OPG/RANKL/RANK system, especially in bone formation and bone resorption. Therefore, adiponectin may prevent osteoporosis by regulating bone metabolism.

OBJECTIVETo study the diagnosis and treatment methods of Mullerian duct cyst.

METHODSThe records of 48 patients with Mullerian duct cyst were reviewed and the diagnosis and treatment methods were compared. From January 1993 to December 1997, eight patients visited the clinic, most of whom complained of the chronic prostatitis symptom. They all underwent the transrectal ultrasonography (TRUS). Seven patients were treated by transperineal TRUS-guided aspiration therapy. One patient with the large Mullerian duct cyst was extirpated by open operation. From January 2002 to December 2007, we treated forty patients. Most of them visited us complained of the obstructive azoospermia. All patients were diagnosed by the TRUS and twelve patients underwent MRI examine. Thirty-nine patients with smaller Mullerian duct cyst were treated by transurethral cyst incision therapy. One patient with large Mullerian duct cyst was extirpated by laparoscopic operation.

RESULTSOne of the eight patients, recurrence was detected at the half-year's follow-up and cured by transurethral cyst incision. All the 40 patients underwent TRUS at three months postoperative follow-up, no cysts recurrence. At the six months postoperative follow-up, ten of thirty-nine patients obstructive azoospermia patients had made their wives pregnant successfully. Nine patients of the other twenty-nine patients had sperms in semen. One 19 years old patient's symptom disappeared.

CONCLUSIONSThe patient with Mullerian duct cyst often complained of chronic prostatitis symptom and the obstructive azoospermia. TURS was the preferred examine method in the diagnosis of the Mullerian duct cyst. And MRI could offer more exact informations. Transurethral cyst incision was effective methods for Mullerian duct cyst. Laparoscopic Mullerian duct cyst resection was a good choice for the large cysts.
