OBJECTIVETo compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).
METHODSForty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.38 ± 4.24) and (26.90 ± 3.14) years, with BMIs of (27.77 ± 0.77) and (28.07 ± 2.28) kg/m² and penis lengths of (3.51 ± 0.46) and (3.50 ± 0.59) cm, respectively. The operations were performed under local anesthesia with lidocaine plus ropivacaine mesylate.
RESULTSThe operation time of circumcision was (28.04 ± 2.65) min and that of FDSF was (45.45 ± 3.49) min. At 6 months after surgery, normal penile erection was found in all the patients, the penis length was significantly longer in the FDSF than in the circumcision group ([5.01 ± 0.73] vs [3.70 ± 0.47] cm) , and the rate of satisfaction with penile appearance was markedly higher in the former than in the latter group (3.25 ± 0.71 vs 2.83 ± 0.56).
CONCLUSIONThe foreskin-deglove plus shaft-fix procedure under local anesthesia with lidocaine and ropivacaine mesylate may achieve desirable penile erection and appearance in the treatment of phimosis or redundant prepuce in obese adult patients.

Type 2 diabetes is a complex metabolic disease, accompanied by insulin resistance and elevated blood glucose. As the disease progresses, hyperglucagonemia will occur. Glucagon has a significant effect on glucose increase and energy expenditure. In recent years, several glucagon receptor (GCGR) antagonists were developed. They lowered blood glucose in clinical studies, along with side effects, such as increased blood lipids and elevated liver transaminase. In order to solve these problems, glucagon like peptide 1 receptor (GLP-1R)/GCGR co-agonists were developed, which not only lower blood glucose, but also reduce weight and promote lipolysis. In this review, we will focus on the biological effects of glucagon, the treatments of GCGR antagonists, and GLP-1R/GCGR co-agonists on type 2 diabetes.

Objective To determine the effect of calmodulin-dependent kinase Ⅱ (CaMK Ⅱ ) -ryanodinereceptor pathway signaling in rabbits with left ventricular bypertrophy (LVH) and triggered ventricular arrhythmia.Methods Forty New Zealand rabbits were randomized into four groups ( n =10 per group):the sham operation group,LVH group,KN-93 (CaMKⅡ inhibitor) group (LVH + KN-93),and the ryanodinegroup ( LVH + ryanodine).Rabbits in the LVH,KN-93,and ryanodinegroups were used to establish a left ventricular hypertrophy model by the coarctation of the abdominal aorta,while the rabbits in the sham operation group did not have the coarctation.After eight weeks,action potentials (APs) were recorded simultaneously in the endocardium and epicardium,and transmural electrocardiogram (ECG) was also recorded in the wedge shaped models of rabbits' left ventricular myocardium.Drugs were administered to animals in the KN-93 and ryanodinegroups respectively,and the frequency of triggered APs and ventricular tachycardia were recorded after isoprenaline ( 1 μmol/L),and high-frequency electrical stimulation were given to rabbits.Results The incidences (animals/group) of triggered APs were:sham,0/10 ; LVH,10/10; KN-93,4/10; and ryanodine,1/10.The incidences of ventricular tachycardia induced were 0/10,9/10,3/10,and 1/10,respectively.The incidences of triggered ventricular arrhythmias in the KN-93 group and ryanodine groups tachycardia or ventricular fibrillation were 0/10,7/10,2/10,and 1/10,respectively.The incidences of triggered ventricular arrhythmias in the KN-93 group and ryanodine groups were much lower than that in the LVH group (P < 0.05).Conclusions KN-93 and ryanodinecan effectively reduce the occurrence of triggered ventricular arrhythmia in rabbits with LVH.The CaMK Ⅱ-ryanodine signaling pathway can be used as a novel target site of treating ventricular arrhythmia.

Cardiac hypertrophy is an independent risk factor for sudden cardiac death in clinical settings and the incidence of sudden cardiac death and ventricular arrhythmias are closely related. The aim of this study was to determine the effects of the calmodulin-dependent protein kinase (CaMK) II inhibitor, KN-93, on L-type calcium current (I(Ca, L)) and early after-depolarizations (EADs) in hypertrophic cardiomyocytes. A rabbit model of myocardial hypertrophy was constructed through abdominal aortic coarctation (LVH group). The control group (sham group) received a sham operation, in which the abdominal aortic was dissected but not coarcted. Eight weeks later, the degree of left ventricular hypertrophy (LVH) was evaluated using echocardiography. Individual cardiomyocyte was isolated through collagenase digestion. Action potentials (APs) and I(Ca, L) were recorded using the perforated patch clamp technique. APs were recorded under current clamp conditions and I(Ca, L) was recorded under voltage clamp conditions. The incidence of EADs and I(ca, L) in the hypertrophic cardiomyocytes were observed under the conditions of low potassium (2 mmol/L), low magnesium (0.25 mmol/L) Tyrode's solution perfusion, and slow frequency (0.25-0.5 Hz) electrical stimulation. The incidence of EADs and I(ca, L) in the hypertrophic cardiomyocytes were also evaluated after treatment with different concentrations of KN-92 (KN-92 group) and KN-93 (KN-93 group). Eight weeks later, the model was successfully established. Under the conditions of low potassium, low magnesium Tyrode's solution perfusion, and slow frequency electrical stimulation, the incidence of EADs was 0/12, 11/12, 10/12, and 5/12 in sham group, LVH group, KN-92 group (0.5 μmol/L), and KN-93 group (0.5 μmol/L), respectively. When the drug concentration was increased to 1 μmol/L in KN-92 group and KN-93 group, the incidence of EADs was 10/12 and 2/12, respectively. At 0 mV, the current density was 6.7±1.0 and 6.3±0.7 PA·PF(-1) in LVH group and sham group, respectively (P>0.05, n=12). When the drug concentration was 0.5 μmol/L in KN-92 and KN-93 groups, the peak I(Ca, L) at 0 mV was decreased by (9.4±2.8)% and (10.5±3.0)% in the hypertrophic cardiomyocytes of the two groups, respectively (P>0.05, n=12). When the drug concentration was increased to 1 μmol/L, the peak I(Ca, L) values were lowered by (13.4±3.7)% and (40±4.9)%, respectively (P<0.01, n=12). KN-93, a specific inhibitor of CaMKII, can effectively inhibit the occurrence of EADs in hypertrophic cardiomyocytes partially by suppressing I(Ca, L), which may be the main action mechanism of KN-93 antagonizing the occurrence of ventricular arrhythmias in hypertrophic myocardium.

?AlM: To investigate repeatability and accuracy of a latest Keratograph for evaluating the tear film stability and to compare its measurements with that of traditional examination methods.
?METHODS: The results of noninvasive tear film break-up time ( Nl-BUT ) including the first tear film break-up time ( BUT-f ) and the average tear film break-up time ( BUT - ave ) were measured by Keratograph. The repeatability of the measurements was evaluated by coefficient of variation ( CV ) and intraclass correlation coefficient ( lCC) . Wilcoxon Signed-Rank test was used to compare Nl-BUT with fluorescein tear film break-up time ( FBUT) to confirm the correlation between Nl-BUT and FBUT, Schirmer l test values. Bland-Altman analysis was used to evaluate consistency.
?RESULTS: The study recruited 48 subjects ( 48 eyes ) (mean age 38. 7±15. 2 years). The CV and lCC of BUT-f were respectively 12. 6% and 0. 95, those of BUT-ave were 9. 8% and 0. 96. The value of BUT-f was lower than that of FBUT. The difference had statistical significance ( 6. 16±2. 46s vs 7. 46±1. 92s, P<0. 01). There was significant positive correlation between Nl-BUT and FBUT, Schirmer l test values ( P< 0. 01 ). The scope of 95% limits of agreement (LoA) was 4. 46s in BUT-f and FBUT, while the scope of LoA was 3. 64s in BUT-ave and FBUT.
?CONCLUSlON: Keratograph can provide Nl-BUT data that has a better repeatability and reliability, which has great application prospects in diagnosis and treatment of dry eye and refractive corneal surgery.

OBJECTIVETo explore the clinical results of postoperative rehabilitation of patellar fracture by modified seated position of different knee flexion angles, thereby enrich the therapeutic tool of orthopaedics of traditional Chinese and western medicine and provide the evidences for refinement and modernization of traditional Chinese exercise therapy.
METHODSFrom January 2009 to June 2012,90 patients with patellar transverse fractures were treated with open reduction and internal fixation by tension band wire and rehabilitation exercises. There were 52 males and 38 females, aged from 21 to 77 years old with an average of 50.0 years old. Three methods of rehabilitation exercises were adopted in the patients after fractures clinical union. There were 21 males and 14 females in group A (trained by modified seated position of knee flexion about 60 degree), 21 males and 14 females in group B (trained by modified seated position of knee flexion about 30 degree), 10 males and 10 females in group C (trained by walk). The rehabilitation-training time was 1 month. Fracture healing informations were observed by X-ray films. The Böstman patellar fracture function scores were compared before and after training among three groups.
RESULTSPostoperative follow-up time was 6 months. All fractures obtained bone union and the average healing time was 3 months (ranged,2 to 4 months). Böstman patellar fracture function scores in group A, B, C before training were 18.89 ± 2.19, 18.74 ± 2.03, 18.85 ± 2.92, respectively; there was no significant differences in among three groups (P > 0.05). After training, Böstman patellar fracture function scores in group A, B, C were 29.40 ± 1.14, 26.09 ± 3.86, 25.70 ± 4.09, respectively; group A was highest than other two groups; and there was no significant differences between group A and group B.

Objective To evaluate the functional changes of visual cortex (V1) in patients with primary open angle glaucoma (POAG) by fMRI retinotopic mapping technology. Methods Fifteen POAG patients and 15 healthy volunteers underwent stimulations with fMRI retinotopic mapping stimulus and contrast-reversing checkerboard patterns stimulus on a Siemens Trio 3.0 T MRI whole-body scanner for functional data collection. Comparisons of V1 fMRI responses between the glaucomatous eyes and the healthy eyes of the patients were carried out using paired samples t-test, while independent samples t-test was used to compare V1 fMRI responses and activations between the healthy eyes of patients and the age-, gender- and side- matched eyes of normal people. Differences of V1 cortical functions and visual functions were analyzed by linear correlation analysis when the glaucomatous and the healthy eyes were simulated individually. Results (1) V1 fMRI responses of the individually stimulated glaucomatous eyes[(1.24±0.72)%]were weaker than those of the healthy eyes[(2.18±0.93)%](t=4.757,P<0.01). Comparisons of V1 fMRI responses between the glaucomatous eyes and matched eyes of normal people, as well as between the healthy eyes of patients and the matched eyes of normal people, were performed respectively: the responses in the glaucomatous eyes[(1.24±0.72)%]were weaker than those in the matched eyes of normal people[(2.01±0.65)%](t=-3.011,P<0.01). There was no statistical difference of the responses between the healthy eyes from patients[(2.18±0.93)%]and the matched eyes of normal people[(1.95±0.75)%](t=0.742,P>0.05). (2) Differences of V1 cortical functions were negatively correlated with those of visual functions in the individually stimulated glaucomatous and healthy eyes (r=-0.887, P<0.01). (3) The activated area indexes of V1 cortexes in the healthy eyes from patients (0.72±0.12) were lower than those in the matched eyes of normal people (0.85±0.09) (t=-3.801, P<0.01). Conclusion Cortical function impairment was in accordance with visual function impairment in glaucoma. Located and quantified measurement with fMRI retinotopic mapping was a useful method for clinical follow-up and evaluation of functional alteration of glaucomatous visual cortex, and a potentially useful means of studying trans-synaptic degeneration of visual pathways of in vivo glaucoma.
