By means of the indirect-enzyme conjugation method, we studied the enke-phalin immunoreactivity in the brain of the guinea pigs.A number of brown granules were found to be distributed in the cell body and nerve fibers as well as in the nerve terminals .They are the product of immunoreactions between the leu-enk and the anti-leu-enk-serum or between the met-enk and the anti-met-enk-serum respectively .Some necessary conditions required for the success of the re-action were discussed

ObjectiveTo sum up the diagnosis and differential diagnosis of concealed penis,analyze the indications and advantages of different operative methods for concealed penis.Methods62 children with concealed penis were treated by different surgical operations according to the different types,and the effect of surgical treatment was arelyzed.ResultsOpertaions were successed in all 62 cases,children were discharged after 5 ～ 10 operation days.After follow-up for 3 months to 2 years,62 children had received good recovered with an effective exposure of penis and no severe edema and other complications.ConclusionChildren with concealed penis should be given personalized scheme,choose the best method to extend the length of the penis and improve the penis appearance.

Objective To evaluate β1、β2 and β3-adrenoreceptor mRNA expression in the sepsis rat model and to investigate the influence of the levels of β1、β2(especially β3AR)on heart dysfunction of sepsis rats.Methods The rats were randomly divided into two groups:control group and sepsis group,either group was then divided into four subgroups:6 h,18 h,24 h,36 h,RT-PCR was used to determined β1、β2 and β3-adrenoreceptor mRNA expression.Results The ratio of β1-AR/β-actin mRNA was lower in sepsis groups as compared with control.Among the two groups,the control group had the highest ratio(1.07±0.13)and sepsis 36h group had the lowest(0.59±0.13)with significant difference(P＜0.05).The ratio of β2-AR/β-actin mRNA was lower in sepsis group as mmpared with coatrol,but there was no statistical significance.The ratio of β3-AR/β-actin mRNA was higher in sepsis group as compared with control.Sepsis 36 h group was the highest with an increase of 73%as compared with control(P＜0.05).Conclusion These data suggest that the reduction of β1-AR mRNA and the increase of β3-AR mRNA might contribute to sepsis-related cardiac dysfunction.

Obsessive-compulsive disorder (OCD), which has the main clinical features of intrusive obsessions and compulsive behaviors, is listed as one of the top ten disabling diseases by the World Health Organization.Error related negativity(ERN) is a neurocognitive alarm signal in the case of errors.The individual differences in the ERN reflect the variability in reactivity to errors and to an internally generated threat.More and more studies have reported that ERN amplitudes in OCD have significantly increased.As a result, overactive error-monitoring is a core dysfunction disorder in OCD, which is closely related to the key symptoms of OCD including worry, doubt, repeating check behaviors.In addition, the increased ERN amplitudes are expected to serve as a diagnostic or predictive marker of OCD as well as a potential intervention target of this disease.Therefore, further understanding about the relationship between ERN and pathophysiology of OCD plays an important role in the effective diagnosis and treatment of OCD.The current paper aims to review the research results of ERN in patients with OCD and explore the following issues: the common experiment paradigms of ERN in OCD, the brain region sources of ERN in OCD, the characteristic manifestations of ERN in OCD, influencing factors of ERN and clinical value and application of ERN in OCD.In a word, it will provide reference for clinical practice and scientific research in the future.

Objective To verify the performance of the ADVIA Centaur XP automatic chemiluminescence analyzer produced by the Siemens company in quantitative detection of serum insulin (IRI) and C‐peptide(CpS) .Methods The blood samples from 40 in‐dividuals undergoing the physical examination were detected for calculating the imprecision and bias of IRI and CpS .The linear range of IRI was verified .The reference range of IRI and CpS was verified .Results The intra‐batch variable of coefficient of IRI and CpS was less than 6 .25% ,the inter‐batch imprecision were less than 8 .33% ;the bias of IRI and CpS detection was less than 12 .5% ;the linear range of IRI was 0 .50 - 307 .76 mIU /L ;the detection results of 40 serum samples showed that all IRS were with‐in the reference range provided by manufacturer ,the results in 2 cases of CpS was out of the reference range provided by manufac‐turer ,indicating that it conformed to the relevant requirements .Conclusion The main performance of the ADVIA Centaur XP auto ‐matic chemiluminescence analyzer for detecting IRS and CpS meets the requirements ,which could be used for clinical detection .

Objective To study the effects of cyclooxygenase( COX)?2 selective inhibitors on post?endoscopic retrograde cholangiopancreatography ( ERCP ) pancreatitis ( PEP ) and hyperamylasemia for common bile duct stones. Methods A total of 128 patients with normal serum amylase underwent ERCP from June 2014 to February 2015 in our hospital and were given corresponding drugs to prevent PEP.The pa?tients were divided randomly into four groups:combination group( n=33) , celecoxib group( n=34) , nitro?glycerin group(n=32) and control group(n=29). The serum amylase(AMS), C?reactive protein(CRP) and direct bilirubin( Dbil) after ERCP were measured. Abdominal pain was observed, and the incidence of PEP and post?ERCP hyperamylasemia were recorded. Results The incidence of PEP in combination group, celecoxib group were lower than those in nitroglycerin group and the control group ( 3?03%, 2?94% VS 15?63%, 17?24%),but the difference was not statistically significant(P=0?078).The incidence of post?ERCP hyperamylasemia in combination group and celecoxib group were lower than that in the control group ( 3?03%,5?88% VS 31?03%) with statistically significant difference( P=0?003, P=0?010) . There was no significant difference between nitroglycerin group ( 25%) and control group. The abdominal pain grades of combination group and celecoxib group were lower than those in nitroglycerin group and control group with significant difference(P<0?05). Celecoxib may reduce CRP after ERCP(P=0?001) and nitroglycerin may reduce Dbil after ERCP(P=0?016). Conclusion Celecoxib may reduce the incidence of hyperamylasemia and can help to reduce the abdominal pain and inflammatory reactions after ERCP . Nitroglycerin can help to reduce the Dbil after ERCP .

OBJECTIVE:To investigate the role of clinical pharmacists in the therapy for patient with pulmonary aspergillosis complicated with rhabdomyolysis(RM). METHODS:Clinical pharmacists participated in the therapy for RM patients with pulmo-nary aspergillosis,and assisted physicians to optimize and improve therapy plan from RM therapy,anti-infection and liver protec-tion:stop taking Bicyclol tablet,continue Micafungin for injection 50 mg,ivgtt,qd for anti-infection;suspend liver-protective drug Compound glycyrrhizin;closely monitor therapeutic efficacy and ADR. RESULTS:Physicians adopted the suggestions of clini-cal pharmacists,and the situation of RM were improved. The patient were discharged from hospital 24 d later. CONCLUSIONS:Clinical pharmacists participate in therapy for RM patient with pulmonary aspergillosis and assist physicians to improve therapy plan,which contribute to rational drug use and the safety of drug use.

Objective To discuss treatments of femoral intertrochanteric fractures by external fixators which can prevent complications caused by lying in bed for long periods after operation. Methods After proper closed reduction had the fragments maintained in good position, the fracture was fixed by external fixators through closed pinning under the roentgenoscopy. After the operation the patients with femoral intertrochanteric fractures could conduct early exercises to recover the functions of the fractured limb. Results Compared with traction or inner fixation, this method to treat femoral intertrochanteric fractures showed significant superiority in trauma, healing time, expenditure, functional recovery and complications for the majority of the patients. Conclusion The external fixators are recommendable for patients with femoral intertrochanteric fractures when their bone matrix and physical conditions are good enough.
