Objective To investigate the effects of ulinastatin on pro- and anti-inflammatory cytokines and respiratory index during open heart surgery under CPB. Methods Twenty ASA Ⅱ- Ⅲ patients of either sex (9 males, 11 females) scheduled for elective valve replacement under CPB were randomly divided into two groups of 10 each : control group (C) and ulinastatin group (W) . Patients with hepato-renal dysfunction or taking glucocorticoid were excluded. The patients were premedicated with intramuscular phenobarbital 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with midazolam 0.1 mg?kg-1 , fentanyl 10?g?kg-1 and vecuronium 0.1mg?kg-1 . After tracheal intubation anesthesia was maintained with midazolam and fentanyl. The patients were mechanically ventilated. VT was set at 8-12 ml?kg-1 , RR 10-12 bpm and I: E 1:2. PETCO2 was maintained at 35-45 mg. In ulinastatin group, the patients received ulinastatin 12 000 U?kg-1 of which half was given i.v. before CPB and half was added to the priming fluid, while group C received normal saline instead of ulinastatin. Blood samples were taken from radial artery for determination of plasma TNF-?, IL-6, and IL-10 concentrations and blood gas analysis before operation (T1 ) , 30 min after initiation of CPB (T2), 1 h (T3 ) , 4 h (T4 ) and 24 h (T5 ) after CPB. Respiratouy index (PA-aDO2/ PaO2) was calculated at T1-5 .Results There were no significant differences in sex, age, weight, height, duration of CPB, and aortic cross-clamping time between the two groups. In group C the plasma levels of TNF-?, IL-6 and IL-10 were significantly higher than the baseline values (T1 ) during and after CPB (P

Objective To understand the epidemiological characteristics of imported malaria in Luoyang City,so as to pro-vide the evidence for malaria prevention and control in this city. Methods The Epidemic situation data from network reports, as well as the case survey and the epidemiological investigation data of imported malaria were collected and analyzed in Luoyang City from 2010 to 2013. Results A total of 98 imported malaria cases were reported in Luoyang City from 2010 to 2013,includ-ing 35 cases of vivax malaria,57 cases of falciparum malaria,4 cases of ovale malaria and 2 cases of quartan malaria. All the cases were confirmed by laboratory detection. Seventy-one cases(72.44%)returned from African countries,and 27(27.55%) cases returned from Southeast Asian countries. The majority cases were young man,and 78.57%of the cases were diagnosed by different levels of centers for disease control and prevention. There was no significant seasonal variation in onset time. The medi-an time from onset to seeing doctor was 6 days. Conclusions The epidemic situation of imported malaria is quite serious in Luoyang City. It is necessary to further strengthen the professional training and multi-sectoral cooperation ,and take effective pre-vention and control measures to reduce the hazard of imported malaria.

BACKGROUND: The relationship between liver cancer recurrence and hepatitis B virus recurrence remains poorly understood and it is considered to be related to application of immunosuppressive agent after liver transplantation. OBJECTIVE: To investigate the effects of tacrolimus (FK506) on the proliferation of HepG2.2.15 cells and the replication of hepatitis B virus in vitro. METHODS: HepG2.2.15 cells were in vitro cultured. After passage 3 HepG2.2.15 cells were cultured for 24 hours, they were interfered with different concentrations of FK506. 0 g/L FK506-interfered group served as control group, 50 g/L FK506-interfered group as low-concentration FK506 group, 100 g/L or 500 g/L FK506-interfered group as medium-concentration FK506 group, and 1 000 g/L or 3 000 g/L FK506-interfered group as high-concentration FK506 group. RESULTS AND CONCLUSION: Moderate- and high-concentration FK506 exhibited inhibitory effects on the proliferation of HepG2.2.15 cells, while low-concentration FK506 exhibited no inhibitory effects with correlation. High-concentration FK506 made HepG2.2.15 cells arresting at G0/G1 stage. FK506 decreased CyclinA expression in HepG2.2.15 cells in a dose-dependent manner. Higher concentration of FK506 leaded to lower expression of CyclinA. FK506 did not produce effects on the replication of hepatitis B virus in HepG2.2.15 cells. These results indicate that FK506 inhibits the proliferation of HepG2.2.15 cells in vitro, which occurs possibly due to Cyclin A, but it would not affect the replication of hepatitis B virus in vitro.

Objective To discuss the treatment experience of adrenocorticotropic hormone independent macronodular adrenal hyperplasia (AIMAH).Methods The clinical data of 24 cases of AIMAH from August 1972 to December 2016 were retrospectively analyzed.The cases included 10 males and 14 females with a mean age of 43 (range 26 to 59) years.16 patients presented with typical Cushing syndrome (CS) and 8 patients had weight gain, hypertension or diabetes mellitus without any sign of CS.The circadian rhythm of serum cortisol was abnormal.Low and high dose dexamethasone suppression tests failed to suppress cortisol secretion.The preoperative CT scan showed bilateral enlargement of the adrenal glands with multiple macmnodules.14 patients underwent open surgery, including 5 cases of unilateral adrenalectomy, 6 cases of adrenalectomy combined with contralateral subtotal adrenalectomy and 3 cases of bilateral adrenalectomy simuhaneously.6 patients underwent conventional laparoscopic adrenalectomy,including 2 cases of unilateral adrenalectomy, 2 cases of adrenalectomy combined with contralateral subtotal adrenalectomy and 2 cases of bilateral adrenalectomy.4 patients underwent robot-assisted laparoscopic bilateral adrenalectomy.Results The postoperative pathological examination showed that all patients had bilateral adrenal macronodular or adenomatoid hyperplasia.During the mean follow-up of 68 months (range 3 to 192 months), the clinical symptoms of CS disappeared after surgery in all cases.7 patients who received unilateral adrenalectomy had urinary free cortisol and serum cortisol within normal ranges and no further enlargement of the contralateral gland was noticed.Among the 3 patients who received bilateral adrenalectomy simultaneously, 1 case died of adrenal crisis on the seventh day post-operation.The remaining 2 cases presented with adrenal insufficiency but returned to normal after glucocorticoid replacement therapy.Nelson's syndrome was not observed in other patients.Conclusions The use of bilateral adrenalectomy to treat AIMAH may involve risk.Unilateral adrenalectomy is recommended for an alternative treatment for AIMAH.Controlateral adrenalectomy with lifelong corticosteroid replacement or contralateral subtotal adrenalectomy may be performed if the symptoms have not improved or recurred after unilateral adrenalectomy.

Objective To investigate the infectious status,etiological spectrum and epidemiological characteristics of rotavirus (group A/B/C),calicivirus (novovirus Ⅰ/Ⅱ,sapovirus),astrovirus and enteric adenovirus in diarrhea cases below 5 years old from 2008 to 2015 in Henan provinces.Methods Totally 2541 stool samples were collected from cases below 5 years old in four sentinel hospitals.All stool specimens were tested for group A rotavirus by double antibody sandwich ELISA method.G/P genotyping of group A rotavirus was determined by nested multiplex PCR.Viral RNA was extracted from all samples and rotavirus (group B/C),calicivirus,astrovirus and enteric adenovirus were detected by two-step reverse transcription-polymerase chain reation (RT-PCR)/PCR.Results One thousand four hundred and twenty-one out of 2 541 samples were positive with a total positive rate of 55 .9%,among which,102 were mixed infection.The isolation rate of rotavirus was 36.0% (914 samples)(group A:785 cases,group B:36 cases,group C:93 cases),calicivirus was 12.1 % (308 samples)(novovirus Ⅰ:64 cases,novovirusⅡ:193 cases,sapovirus:51 cases),astrovirus was 5 .9% (151 samples),enteric adenovirus was 1 .9%(48 samples).The group A rotavirus gene type combinations were composed mainly of G9P[8],G2P[4], G3P[8 ],G1P [8 ]and most cases were identified from September to November and March to May. Novovirus Ⅱ was predominant in calicivirus and most cases were identifed between March and May. Rotavirus or calicivirus infection was mainly among children aged 4—12 months or 3—5 years, respectively.Clinical manifestations included fever,diarrhea,vomiting,dehydration.Gender and region distributions differed according to the types of pathogen.Conclusions Group A rotavirus and novovirus Ⅱare the major viral pathogen in diarrhea cases younger than 5 years old in Henan province.Different viral infections exhibit extinct epidemiologic and clinical characteristics.
