Objective To explore the change of plasma orexin A concentration and the correlation between plasma orexin A concentration and energy intake in obese children.Methods Fasting plasma orexin A concentrations,boaly mass index(BMI) and energy intake were measured in 48 obese children(obese group) and 48 healthy children(healthy control group),and these indexes were compared,the correlation between plasma orexin A concentration and BMI,energy intake were analyzed.Results 1.The plasma orexin A concentration in obese group was significantly lower than that in healthy control group(F=5.632 P=0.008).2.In obsess group,there were negative correlation between plasma orexin A concentration and BMI(r=-0.478 P=0.012),positive correlation between plasma orexin A concentration and total energy intake(r=0.503 P=0.007),fat intake(r=0.659 P=0.006) and protein intake(r=0.381 P=0.026),and there was negative correlation between plasma orexin A concentration and carbohydrate(r=-0.316 P=0.022).3.In healthy control group,there were negative correlation between plasma orexin A concentration and BMI(r=-0.491 P=0.018),positive correlation between plasma orexin A concentration and total energy intake(r=0.512 P=0.009),fat intake(r=0.406 P=0.005),protein intake(r=0.313 P=0.020),and carbohydrate(r=0.432 P=0.025).Conclusions Orexin A may be involved in regulation of energy metabolism in obese children,and the interaction between plasma orexin A and energy intake might be different in different nutritional status in children.

OBJECTIVETo analyze the efficacy of adefovir dipivoxil combined with bicyclol in treatment of HBeAg-positive chronic viral hepatitis B (CHB).

METHODSA total of 91 patients with CHB were randomized into experimental group and control group to be treated. The patients in experimental group (46 samples) received adefovir dipivoxil orally 10 mg daily and bicyclol orally 150 mg daily for 48 weeks and those in control group (45 samples) received adefovir dipivoxil orally 10 mg daily alone for 48 weeks. The serum aminotransferace (ALT/ AST), HBV-DNA, HBeAg/antiHBe were observed before and after treatment.

RESULTSCompared with pretreatment, the serum aminotransferace were all decreased obviously in two groups, the experimental group is better (P < 0.05). HBVDNA negative conversion rate was significantly higher in experimental group than in the control group (47.8% vs. 31.1%, P < 0.05). There were nostatistically differrence between the two groups in the portion of HBeAg loss rate and HBeAg seroconversion rate. There were no obvious adverse reaction in the study.

CONCLUSIONAdefovir dipivoxil combined with bicyclol is efective in the treatment of chronic hepatitis B.

OBJECTIVETo research the application and clinical effect of titanium elastic nails (TEN) for the treatment of closed clavicular fracture in elder children.

METHODSFrom October 2010 to December 2012,16 elderly children with clavicular fracture of elder children were treated with internal fixation, including 9 boys and 7 girls with an average age of 14.2 yeats old ranging from 9 to 17 years. The mean time between injury and surgery was 2 to 6 days. Thirteen patients had a transverse fractures; 3 patients had a oblique fractures, excluding the long-oblique patients. Neer function score after 3 months follow-up and the shoulder activity degree after 3 weeks followed were compared respectively between the injured side and healthy side. Fracture reduction and healing were followed up by X-rays to analyze internal fixation with TEN technique.

RESULTSAll patients were healed well after surgery. There were 2 cases with soft tissue irritation. No cases of infection, TEN broken, delayed healing or skin bursting were observed. All patients were followed up for 3 to 10 months,with an average of 7.2 months. There were no significant differences (t=2.12, P>0.05) between the healthy side (98.75±2.70) and injured side(96.69±6.22)of Neer score at 3 months during followed up. The shoulder activity at 3 weeks during followed up was different between both sides (P<0.05). The intramedullary nail was removed after X-rays at 12-18 weeks during followed up showed good bone healing,and the shoulder function was recovered well.

CONCLUSIONInternal fixation with TEN for the treatment of clavicular fracture has advantages of a limited invasion, beauty, safety and reliability. This technique provides an ideal fixation option for the treatment of clavicular fracture in elder children.

OBJECTIVETo observe the efficacy and safety of Yigu capsule (YGC, a Chinese herbal compound preparation) in treating postmenopausal osteoporosis (PMO) and to explore its possible mechanism.

METHODSThe clinical study was conducted adopting prospective, randomized, double blinded method for 6 months with placebo and positive controls. Two hundred and ten PMO patients with confirmed diagnosis were divided into the YGC group, the osteocalcin group and the placebo group, they were treated with YGC, osteocalcin capsule and placebo capsule, respectively. The symptoms, as new fracture and ostealgia, bone mineral density (BMD) of the 2nd to the 4th lumbar vertebrae (L24) and upper segment of femur, blood and urinary indexes for bone metabolism, sex hormone level and adverse reaction were observed.

RESULTSIn the YGC group, the total effective rate was 95.50%, no new fracture occurred, which was significantly better than that in the other two groups (P < 0.05). The increase of BMD was 9.83% in L2-4, 4.09% in femoral neck, 4.60% in Wards triangle, 3.00% in greater trochanter, which were better than those in the placebo group (P < 0.05, P < 0.01). As compared with the placebo group, in the YGC group, levels of urinary oxyproline hydroxyproline/creatinine, urinary calcium/creatinine were lower, serum and bone alkaline phosphatase, osteocalcin, estradiol, and estradiol/testosterone were higher, but with no difference in level of testosterone. In the observation period, no abnormal findings in blood and urine routine examination as well as in liver and renal function were found. Mild, transient gastro-intestinal response occurred in individual patients but it didn't affect the treatment.

CONCLUSIONYGC could treat PMO effectively, it could obviously increase the BMD of lumbar vertebrae and hip, elevate the alleviating rate of ostealgia and incessant motion time, without new compressive fracture of vertebrae, and without any related adverse reaction. YGC could not only promote the formation, but also inhibit the absorption of bone, and increase the sex hormone level, therefore, it is a pure Chinese herbal compound preparation that worths further deep research and development.

OBJECTIVETo investigate the incidence of JAK2V617F gene point mutation in patients with myeloproliferatives diseases (MPD) and its clinical significance.

METHODSGenomic DNA from bone marrow and peripheral blood cells were extracted from 68 patients with MPD. Allele specific polymerase chain reaction was used to amplify the exon 12 of JAK2 gene which harbours V617F mutation. The PCR products were identified by DNA sequencing. JAK2V617F gene point mutation and its impact on peripheral blood cells were analyzed.

RESULTSThe incidence of JAK2V617F mutation in 68 patients with MPD was 65.28 %. The positive rate of JAK2V617F point mutation was 77.77 % in patients with PV (36/59), 56.52 % in patients with ET (23/59) and 44.44 % in patients with IMF (4/9). In all groups, the incidence of JAK2V617F point mutation in bone marrow and peripheral blood were equal. Patients with JAK2V617F mutation in PV group had higher counts of white blood cell and hemoglobin in peripheral blood than patients without JAK2V617F point mutation (P <0.05). Patients with JAK2V617F mutation in ET group had higher counts of white blood cell than those without JAK2V617F mutation (P <0.05); there was no significant difference in platelet count.

CONCLUSIONJAK2V617F point mutation can affect the hematologic features, which may be of diagnostic value for MDP with negative BCR-ABL gene.

In order to investigate the safety and efficacy of endoscopic retrograde cholangiopancreatograpy (ERCP) in liver cirrhosis patients with common bile duct stones, we retrospectively analyzed data of 46 common bile duct stones patients with liver cirrhosis who underwent ERCP between 2000 and 2008. There were 12 cases of Child-Pugh A, 26 cases of Child-Pugh B, and 8 cases of Child-Pugh C. 100 common bile duct stones patients without liver cirrhosis were randomly selected. All the patients were subjected to ERCP for biliary stones extraction. The rates of bile duct clearance and complications were compared between cirrhotic and non-cirrhotic patients. The success rate of selective biliary cannulation was 95.6% in liver cirrhotic patients versus 97% in non-cirrhotic patients (P>0.05). The bile duct clearance rate was 87% in cirrhotic patients versus 96% in non-cirrhotic patients, but the difference was not statistically significant. Two liver cirrhotic patients (4.35%, 2/46) who were scored Child-Pugh C had hematemesis and melena 24 h after ERCP. The hemorrhage rate after ERCP in non-cirrhotic patients was 3%. The hemorrhage rate associated with ERCP in Child-Pugh C patients was significantly higher (25%, 2/8) than that (3%, 3/100) in non-cirrhotic patients (P<0.01%). There was no significant difference between these two groups in the rate of post-ERCP pancreatitis (PEP) and cholangitis. ERCP is safe and effective for Child-Pugh A and B cirrhotic patients with common bile duct stones. Hemorrhage risk in ERCP is higher in Child-Pugh C patients.

OBJECTIVETo investigate the effect of operative treatment for anteromedial facet fracture of the coronoid process of ulna,and to study its surgical exposures and fixation techniques.

METHODSFrom March 2005 to March 2010,18 patients with anteromedial facet fracture of the coronoid process of ulna were treated with open reduction and internal fixation. There were 12 males and 6 females with an average age of 37.8 years. A single midline posterior incision was used to expose the entire elbow joint. After elevating the full-thickness skin flaps, a lateral incision was made to expose and repair the lateral collateral ligament. Three intervals in the flexor-pronator musculature were used to gain access to the coronoid,depending on the size of the fracture fragment and the planned fixation technique. Fractures were fixed by using mini-plate or with screws. The therapeutic effects were evaluated by Mayo Elbow Performance Score (MEPS) and system of Broberg & Morrey.

RESULTSSeventeen patients were followed up, no patient complained pain and elbow unstable at a mean follow-up period of 38 months(1 to 6 years). The fractures were clinically healed at an average time of 11.6 weeks(ranged from 8 to 16 weeks). The average MEPS was 95.4+/-4.6 (ranged, 82 to 100). The average functional rating of system of Broberg & Morrey was 92.3+/-5.8 (ranged,75 to 100).

CONCLUSIONOpen reduction and internal fixation is effective to reach anatomical reduction and strong fixation for the treatment of anteromedial facet fracture of the coronoid process of ulna.

This paper was aimed to study the effect of genistein (GST) on L-type calcium current (I(Ca,L)) in isolated guinea pig ventricular myocytes using whole cell patch-clamp recording technique. The results are as follows. (1) GST (10, 50, 100 micromol/L) reduced the voltage-activated peak amplitude of I(Ca,L) in a concentration-dependent manner. Daidzein (100 micromol/L), a structural analogue of GST which has little or no inhibitory effect on tyrosine kinase, produced no effect over the same concentration range on I(Ca,L) (n=5, P>0.05). (2) GST up- shifted the current-voltage (I-V) curve, but the characteristics of I-V relationship were not significantly altered, and the maximal activation voltage of I(Ca,L) was not different from that of control. GST did not affect the activation kinetics of I(Ca,L). (3) GST markedly shifted the steady-state inactivation curve of I(Ca,L) to the left, and accelerated the voltage-dependent steady-state inactivation of I(Ca,L). V(0.5) value was -28.6 +/-0.6 mV in the control and -32.8 +/-1.1 mV in the presence of GST. The kappa values were 5.8 +/-0.5 mV and 6.5 +/-0.9 mV, respectively (n=6, P<0.05). (4) GST markedly shifted the curve of time-dependent recovery of I(Ca,L) from the steady-state inactivation to the right, and slowed down the recovery of I(Ca,L) from inactivation (n=7, P<0.01). (5) Sodium orthovanadate (1 mmol/L), a potent inhibitor of tyrosine phosphatase, significantly inhibited GST-induced inhibition (n=6, P<0.01). From the results obtained it is concluded that genistein inhibits I(Ca,L) and acts on the inactivated state of L-type calcium channel. This inhibitory effect of GST involves protein tyrosine kinase inhibition in guinea pig ventricular myocytes.
