Since the China's new healthcare reform has launched , beneficial policies introduced by the central and local governments has promoted the rapid development of private hospitals .This paper taking Sichuan Province as an ex-ample analyzes the development of private hospitals from four points of view:hospital amount, scale, location and services package, using 2002—2014 hospital-level data, which provides decision support for formulating and improving relative pol-icies.As per the analysis of the data at hand , it has been confirmed that private sector has developed quickly during the 13 years, with the number of hospitals increasing by 19.2%annually.Private hospitals were mainly of small-scale.Although the proportion of services provided by privates sector has grown yearly , it was merely 14.5%in 2014.The hospital location that the private sector selected concentrated mainly in developed regions , but the proportion of private hospital in the un-derdeveloped region has risen steadily .In terms of types of service provided , there were certain differences between private and public sector.Compared to the public sector, the private sector provided a higher proportion of specialized medical services, concentrating on otolaryngology , cosmetic plastic surgery , cardiovascular services , etc.

Aim To explore the changes of protein expression pattern of myocardial tissues in mini-pig with coronary heart disease. Methods Based on the model of mini-pig with coronary heart disease,the total proteins of myocardial tissues from each group were separated by two dimensional gel electrophoresis (2-DE).Protein exeprssion pattern in normal and model group was contrasted by Image Master 2D Elite 6.01 analysis software. Then the different proteins were identified by MALDI-TOF-MS. Results Compared with normal group,14 proteins had been determined to change:13 proteins were up-regulated and 1 proteins specifically expressed in mini-pig myocardial tissues of the disease. With the search engine MASCOT,4 proteins including HSPA8 (Hsc70)protein,apolipoprotein A-Ⅳ(apoA-Ⅳ),albumin and desmin were identified.Conclusions These four proteins may play an important role in the occurrence and development of coronary heart disease. The result will be further validated by other biological methods.

Objective:To evaluate the rehabilitation efficacy of early mobilization based on collaboration care model for patients with laparoscopic colorectal surgery.Methods:Cluster sampling method was used in the department to recruit colorectal cancer patients with laparoscopic surgery. The control group (49 cases) received routine perioperative care and exercise, and the intervention group (47 cases) received the coordinated early mobilization combined with routine perioperative care and exercise, from January to March 2019. Primary outcome were health status and the proportion of patients returning to preoperative functional walking capacity (6-min walk test) at 4 weeks after surgery. The in-hospital mobilization (time out-of-bed), time to achieve discharge criteria, time to recover gastrointestinal function and complication rate were explored.Results:In intervention group,89.4%(42/47) of patients achieved mobilization target on 4 days after surgery compared with 42.6%(20/47) on the day of surgery. Time out of bed were greater in the intervention group compared with the control group, and there were differences between the two groups( Z values were -8.437--7.381, P<0.01). Time to recover gastrointestinal function and the recovery of energy on 3 days after surgery were (58.74±17.41) h, (59.02±9.46) points in the observation group, and (71.82±21.53) h, (62.61±7.68) points in the control group, and there were significant differences between the two groups ( t values were -3.263, -2.046, P<0.05). But other outcome measures were not different between the two groups ( P>0.05). Conclusions:For colorectal laparoscopic surgery patients, the coordinated early mobilization improved the adherence to ambulation, in-hospital mobilization, time to recover gastrointestinal function and recovery of energy to promote rehabilitation.

There were 3 000 Zhuangs,1 102 Miaos, and 1 283 Yaos in Baise City of Guangxi,who were enrolled in this population sampling stratfying survey. Height, weight, blood pressure, fasting blood glucose, and lipids were determined, and compared with those of 2 000 Hans of the same town. The prevalence of hypertension and metablic syndrome in Zhuang inhabitants was high, so were the disorders of glycemia and lipidemia, while in Miao and Yao minorities, the prevalences were comparatively lower. The awareness, treatment, and control of hypertension in these minorities were insufficient.

Objective To evaluate diagnostic value of pit pattern analysis on detection of early colorectal carcinoma. Methods 4176 patients were examined with colonoscopy and had the mucosal lesions stained with 0.4% indigo carmine, and part of them observed with magnifying endoscope and stereomicroscope, then compared the mucosal crypt patterns (the pit patterns Kudo classification) with pathologic diagnosis. Results There were 955 protruded and flat lesions on the large intestine mucosa in 752 patients, and among them there are 14 early cancers, 209 advanced cancers, 76Ⅱa、Ⅱb、Ⅱc、Ⅱa+Ⅱc lesions. We also found 43 laterally spreading tumors (LST) ranging from 16 to 110 mm in diameter, 2 for pit Ⅱ,18 for pit Ⅲ L, 19 for pit Ⅳ, 1 for pit Ⅴ A, 1 for Ⅴ N. The pit pattern of the most non neoplastic lesions was type Ⅰ or Ⅱ, which is about 85.4% (303/355), and the type of the adenomas was type Ⅲ or Ⅳ, about 86.0% (504/586). All the invasive carcinomas'pit patterns were type Ⅴ and there were 8 for type Ⅴ (2 Ⅴ A, 6Ⅴ N) among 14 early carcinomas. Conclusion Pit pattern analysis is a very important tool to determine the nature of lesions, which helps to decide the kinds of later therapeutic intervention.

To investigate the interaction and involvement of sodium hydrosulfide (NaHS), a H(2)S donor, on hippocampus of rats suffering from sepsis-associated encephalopathy, rats were subjected to cecal ligation and puncture (CLP)-induced sepsis. Adult male Sprague-Dawley rats were randomly divided into four groups: Sham group, CLP group, CLP+NaHS group and CLP+aminooxyacetic acid (AOAA, an inhibitor of H(2)S formation) group. The four groups were observed at 3, 6, 9, 12 h after treatment. We examined hippocampal H(2)S synthesis and the expression of cystathionine-β-synthetase (CBS), a major enzyme involved in the H(2)S synthesis in hippocampus. CBS expression was detected by reverse transcription polymerase chain reaction (RT-PCR). The concentrations of inflammatory cytokines (TNF-α, IL-1β) were determined in hippocampus by using enzyme-linked immunosorbent assay (ELISA). Neuronal damage was studied by histological examination of hippocampus. In CLP group, H(2)S synthesis was significantly increased in hippocampus compared with sham group and it peaked 3 h after CLP (P<0.05). Sepsis also resulted in a significantly upregulated CBS mRNA in hippocampus. The levels of TNF-α and IL-1β in the hippocampus were substantially elevated at each time point of measurement (P<0.05), and they also reached a peak value at about 3 h. Administration of NaHS significantly aggravated sepsis-associated hippocampus inflammation, as evidenced by TNF-α and IL-1β activity and histological changes in hippocampus. In septic rats pretreated with AOAA, sepsis-associated hippocampus inflammation was reduced. It is concluded that the rats subjected to sepsis may suffer from brain injury and elevated pro-inflammatory cytokines are responsible for the process. Furthermore, administration of H(2)S can increase injurious effects and treatment with AOAA can protect the brain from injury.

Objective To observe and comparatively analysize the effect of intraperitoneal injection of hydrogen and hydrogen-rich saline in neonatal rats with hyperoxia-induced lung injury.Methods Sprague-Dawley(SD) newborn rats were randomly divided into six groups(n=10).air group(A),air+ hydrogen-rich saline group(B),air+hydrogen group(C),hyperoxia group(D),hyperoxia+hydrogen-rich saline group (E) and hyperoxia+ hydrogen group(F).The group A,B and C were exposed to air and group D,E and F were exposed to 95 ％ oxygen.The group B and E were intraperitoneally injected with hydrogen-rich saline (10 mL/kg,twice daily),while the groups C and F with hydrogen (10 mL/kg,twice daily).The group A and D were injected with normal saline(10 mL/kg,twice daily).Lung tissue and serum samples were collected on 15 d of experiment.The pathological changes of lung tissue and radiate alveoli count (RAC) were observed by HE staining.The content of HYP in lung tissue was detected by the alkaline hydrolysis method,serum SOD and MDA levels were measured.The expression of α-SMA in lung tissue was detected by immunohistochemistry SP method.Results Compared with the A group,RAC and SOD activities in the D group were significantly decreased,while the HYP and MDA levels and α-SMA expression were significantly increased.Hydrogen intervention could significantly alleviate these changes caused by hyperoxia.while intraperitoneal injection of hydrogen got better effect than intraperitoneal injection of hydrogen-rich saline.Conclusion Hydrogen can extenuate the indexes of hyperoxia-induced lung oxidative damage,impairment development and fibrosis to a certain extent.Intraperitoneal injection of hydrogen has slightly better effect than hydrogen-rich saline.

Objective To identify the differentially expressed genes in cardinal ligament between patients with pelvic organ prolapse ( POP) and postmenopausal women without POP by Human Genome Expression Chip and explore the potential molecular mechanism involved in POP.Methods From January to May,2007,cardinal ligament samples were obtained from 3 postmenopausal patients with POP-Q stage Ⅲ and 3 postmenopausal patients underwent hysterectomy due to other benign gynecologic diseases without POP in Peking Union Medical College Hospital.HE and Masson's trichrome staining was used to verify tissue origin and inspect histological changes.Those differentially expressed genes in cardinal ligaments were identified by Human Genome Chip and further interrogated with Gene Ontology (GO) and Pathway Analysis.Those remarkable expressed genes were confirmed by qRT-PCR.Results Alterations of ligament architecture in POP patients included disarrangement and collapse of smooth muscle bundles and collagen fibers.A total of 179 differentially expressed genes were screened between POP and non-POP cardinal ligament tissue,including 20 functional unknown genes.A total of 107 genes were upregulated in POP group,while 72 genes downregulated.Those differentially genes were revealed associated with multiple functional proteins and metabolic pathways by biological analysis.Among these,Wnt signaling pathway exhibited the most remarkable changes.Real-time quantitative PCR showed the genes of COL1Al,DKK1,SFRP1,FZD5,WNT16b in POP group (2.98 ±1.40,3.03 ±0.48,8.13 ±4.42,5.19 ±3.50,12.40± 3.88) were upregulated significantly compared with non-POP group (1.09 ±0.08,1/20 ±0.18,0.41 ± 0.51,0.87 ±0.24,1.40 ±0.47; P < 0.05 ).Conclusions The pathophysiology of POP is complex and associated with multiple functional proteins and metabolic pathways.Among these,the antagonist DKK1,SFRP1 in Wnt signaling pathway may contribute to a neurodegenerative role in POP development.
