Objective Different methods were used for the analysis of different medical and health institutions in Henan Province in 2012 of hospital bed utilization,to find bed utilization problems,and provide reference for the rational allocation of resources.Methods Static beds utilization model method (SBMA)and the method of rank sum ratio(RSR)were used for planning of data in“2012 health statistics yearbook of Henan province”,for comprehensive analysis of bed utilization efficiency.Results Among the medical and health institutions in Henan province in 2012,general hospitals,maternal and children hospitals(centers)are found with higher utilization of hospital beds,while other institutions (nursing homes),community health service centers(stations)are found lower.Conclusion Henan Province in 2012 was found on the whole with efficient utilization of hospital beds,yet with rooms of improvement for different medical institutions,especially those at the primary level.

Objective To find out the possession and utilization of urban medical resources in Henan as well as other factors like medical quality, service level and human resources. Methods A general investigation was made of the possession and structure of health resources and the level of medical services in second tier urban hospitals and above in 18 cities of Henan Province. Results There are altogether 182 second tier urban hospitals in the province, with a total of 51 107 beds and a total of 22 859 doctors. The ratio of doctors to nurses is 1∶1 04, the bed utilization rate is 65 55%, the bed workdays are 234 63 days, the average bed turnover frequency is 15 51 times, and the average length of stay is 13 87 days. The average income surplus per hospital is 1 502 700 yuan, with the income from the sale of pharmaceuticals accounting for 44 67% of the total income. Conclusion The operating efficiency of second tier urban hospitals and above in Henan Province is close to the average national level, the structure of hospital allocations needs readjustment, and the percentage of income from the sale of pharmaceuticals is on the high side.

Objective To study the health state and service of the elderly in the Tongbai community. Methods The educational degree, disease histories, daily living capability, health care demand and the controlled state of hypertension and diabetes were recorded by questionnaires and physical examination. Results Overweight or obesity (66.1%) was the common disease, hypertension (42.2%) next, then coronary disease (10.0%) and diabetes (9.1%). Nearly 43.3% hypertension patients never or seldom measured their blood pressure. The rate of ideal blood pressure was lower than 25%. 30.4% diabetes patients never or seldom measured their fasting glucose and 69.3% patients never or seldom measured their post-meal glucose. 46.1% of the elderly required one or more kinds of community health services, in which annual health examination was 32.6%, and the next was health guide (23.0%), 53.9% of the elderly had no requirement of community services except medical care. Conclusion The elderly in community had high prevalence and poor control of chronic diseases. They did not fully understand the community health services, which brought the challenges to the medical care, health prevention, health education and reasonable utility of hygiene resources in community health services.

Objective To evaluate the efficacy and outcomes with the use of a saline-coupled bipolar sealer during liver resection.Methods 101 patients underwent liver resection for primary hepatic carcinoma at the People's Hospital Affiliated to Zhengzhou University from August 2015 to December 2016.The patients were divided into two groups according to whether the Aquamantys(R) system was used or not.In group A (n =62) the clamp crushing technique was used for liver parenchymal transection.In group B (n =39) the Aquamantys(R) system was used.The intraoperative and postoperative complication rates were compared.Results The operation time in group B was significantly longer than group A (216.4 min vs.253.5 min,P ＜ 0.05).The intraoperaitve blood loss in group B was significantly less than group A (381.1 ml vs.257.2 ml,P ＜ 0.05),and less blood transfusion was required (211.3 ml vs.90.9 ml,P ＜ 0.05).The volume of abdominal drainage fluid in group B in the first and the 5th day was significantly less than group A (242.6 ml vs.199.2 ml,P＜0.05;84.3 ml vs.70.4 ml,P＜0.05,respectively).The drainage tube in group B was taken off earlier than in group A (8.1 d vs.7.0 d,P ＜ 0.05).The average hospitalization stay after surgery in group B was also significantly shorter (13.4 d vs.11.6 d,P ＜ 0.05).There was no significant difference in the overall postoperative complication rate (P ＞ 0.05) between the 2 groups,and no death was observed.Conclusion The use of a saline-coupled bipolar sealer (Aquamantys(R)) in liver resection for hepatocellular carcinoma was associated with less intraoperative blood loss and was better for the patients' postoperative recovery.

Objective To investigate the personality traits, anxiety and depression in patients with leukemia. Methods A cross-sectional survey was performed in 120 patients with leukemia and 118 age and gender-matched controls. Personality was assessed using the Type A Behavior Pattern Questionnaire (TABPQ). Emotion was ascertained using the self-rating anxiety scale (SAS) and self-rating depression scale (SDS). The relationship between personality type A and anxiety and depression was evaluated by Pearson correlation analysis. Results The prevalence of personality type A was significantly higher in patients with leukemia than healthy controls [71.67 % (86/120) vs. 30.51 % (36/118), P< 0.01]. Patients with leukemia also had higher prevalence of anxiety and depression compared with healthy controls [36.67%(44/120) vs. 9.32%(11/118), P< 0.01; 29.17 % (35/120) vs. 5.93 % (7/118), P< 0.01]. Pearson correlation analysis showed that time-hurry (TH) and competition-hostility (CH) of personality type A correlated positively with anxiety (r=0.292, r= 0.277, respectively; both P< 0.05). Conclusion TH and CH of personality type A are associated with anxiety in leukemia patients.

Objective To study the spinal neurocyte apoptosis and the changes of p53 in chronic fluorosis rats,and the improvement after drinking no fluoride water.Methods One hundred twenty Wistar rats were divided into 4 groups by random number table method according to body mass,30 rats in one group fed with high concentration NaF water (200 mg/L) to make fluorosis model and classified as high fluoride group;other 30 rats were fed with distilled water as control group;another 30 rats were fed with high concentration NaF water (200 mg/L) for 12 weeks,then fed with distilled water for 12 weeks and classified as defluorination group;the rest 30 rats were classified as defluorination control group.The content of fluoride in urine was tested after the 4th,8th,and 12th weeks.Then the content of fluoride in urine of defluorination group and defluorination control group was tested.The high fluoride group rats and control group rats were killed after 12th week.Defluorination group rats and defluorination control group rats were killed after 24th week.Their spinal cord was collected.The expression of p53 protein in spinal cord was detected by immunohistochemistry and Westem blotting.Apoptosis of the neurocyte was quantitatively analyzed by flow cytometry (FCM).Results By FCM,apoptosis of neurocyte was increased in both high fluorosis group rats and defluorination group rats compared with those in control group rats [(3.36 ± 0.71)％ vs.(0.78 ± 0.65)％;(3.47 ± 0.56)％ vs.(0.83 ± 0.64)％,t =14.680,17.003,all P ＜ 0.01)],but no difference was found between these two groups [(3.47 ± 0.56)％ vs.(3.36 ± 0.71)％,P ＞ 0.05)].Immunohistochemistry and Western blotting revealed that p53 expression in spinal cord of high fluorosis group rats was increased compared with those in control group rats (422.69 ± 12.35 vs.177.82 ± 14.16;253.37 ± 10.42 vs.87.14 ± 7.39,t =77.212,72.988,all P ＜ 0.01).And p53 expression in spinal cord of defluorination group rats was increased compared with those in control group rats (418.75 ± 11.84 vs.163.47 ± 8.57;248.29 ± 10.23 vs.98.74 ± 11.52,t =95.663,53.167,all P＜ 0.01).But the differences were not statistically significant (418.75 ± 11.84 vs.422.69 ± 12.35;248.29 ± 10.23 vs.253.37 ± 10.42,t =1.261,1.906,all P ＞ 0.05).Conclusions There is apoptosis of neurocytes in the spinal cord of chronic fluorosis rats;overexpression of p53 probably plays an important role in the mechanism of damage induced by excessive fluorine.Apoptosis can not be recovered after defluorination for a short time,and persistent overexpression of p53 may be one of the reasons that apoptosis of neurocytes in the spinal cord can not decrease.

Objective To study the treatment of abdominal compartment syndrome(ACS) secondary to fulminant acute pancreatitis (FAP).Method A retrospective study was conducted from Jan.2009 to Dec.2011 to analyze the therapeutic results of 18 patients with ACS secondary to FAP.Results Three out of 7 patients who received non-operative therapy died (mortality rate 42.9％).Three out of 11 patients treated with early surgery died (mortality rate 27.3％),which was significantly better than those patients treated conservatively.Conclusion A reduction in intra-abdominal pressure improved the function of the viscera in the treatment of ACS secondary to FAP.The decompressive effects of early surgery was efficacious,and it reduced the mortality rate.

Objective To discuss the diagnosis and surgical treatment of solid pseudopapillary tumor (SPTP) of the pancreatic head.Methods From January 2008 to August 2013,the clinicopathological data of 12 patients who were diagnosed and surgically treated in our hospital for this condition were analyzed retrospectively.Results There were 11 women and 1 man,the mean age was 28.7 years,with a range from 11 to 43.The mean diameter of the tumor was 7.5 cm(2 ～ 15 cm),6 of 12 of these tumors were more than 10 cm.Seven patients underwent pancreaticoduodenectomy,2 duodenum-preserving pancreatic head resection,2 local resection of tumor,1 palliative resection,1 pancreaticoduodenectomy combined with resection of part of the portal vein.All the diagnoses were confirmed by postoperative histopathology.In a follow-up which ranged from 3 to 65 months,all the patients were alive with no evidence of disease recurrence.Conclusions Most of the SPTPs of the pancreatic head were huge.The diagnosis was difficult.Complete tumor resection is the best treatment.

Objective To evaluate the procedure and the therapeutic efficacy of duodenumpreserving pancreatic head resection (DPPHR) in treating benign lesions in the head of the pancreas.Methods From February 2003 to August 2011,DPPHR was performed in 21 patients with benign lesions in the head of the pancreas.Thirteen patients were male and eight were female.Age ranged from 30 to 48 years,and the lesions ranged from 2.0 cm to 5.6 cm in diameter.Posterior superior pancreaticoduodenal artery was conserved in all patients.Results There was no hospital death.Pancreatic fistula was the main and the most often morbidity,occurring in 33.3％.After operation all patients with preoperative abdominal pain were completely pain free.Preoperative hypoglycemia in 2 patients turned to eugycemia.There was no recurrences report during following up.Concl~ions DPPHR was safe and effective in treating benign lesion in the head of pancreas.It was important in preserving blood supply to the duodenum by posterior superior pancreaticoduodenal artery.

AIM: To investigate the effects of caveolin-1 (Cav-1) scaffolding domain peptide, cavtratin, on lipopolysaccharide (LPS)-induced mouse acute lung injury and heme oxygenase-1 (HO-1) activity.METHODS: Adult male BALB/c mice were randomly divided into 6 groups (n=8 to 10): control, Antennapedia internalization sequence (AP), LPS, LPS+hemin, LPS+ hemin+cavtratin and LPS+hemin+cavtratin+zinc protoporphyrin IX (ZnPP) groups.After LPS administration for 24 h, the lung pathological changes, the wet/dry weight (W/D) ratio of lung tissues, total cell number in bronchoalveolar lavage fluid and serum lactate dehydrogenase activity were measured.The co-localization of HO-1 and Cav-1 was displayed by immunofluorescence, and the HO-1 activity were detected.The mRNA expression of pro-inflammatory cytokines IL-1β, IL-6, TNF-α, MCP-1 and iNOS was detected by real-time PCR.RESULTS: The mice in LPS+hemin+cavtratin group had the decreased interaction between HO-1 and Cav-1, and the increased HO-1 activity compare with LPS group (P<0.05).Compared with LPS group, the pulmonary damage was attenuated in LPS+hemin+cavtratin group, and the injury indexes, including W/D ratio, total cell number in bronchoalveolar lavage fluid and lactate dehydrogenase activity in the serum, and the mRNA expression of inflammatory cytokines all decreased (P<0.05).HO-1 activity inhibitor ZnPP abolished the above protective effect of cavtratin on the lung tissues with LPS-induced acute lung injury.CONCLUSION: Cavtratin has beneficial effects on the lung with LPS-induced acute injury by restoring the HO-1 activity.
