Objective To understand the issues in the conversion of private medical institutions and explore the possible options.Methods Case study and in-depth interview were employed in 6 converted medical institutions.Results The reasons for conversion were diversified,and the process was not standardized.The attitudes towards how to deal with the net assets differed so much among the executives.The legislation and supervision by the government were still under-developed.Conclusion The process for the conversion should be standardized and the ownership of the net assets should be clearly defined.The legislation and supervision on private medical institutions should be enhanced.

In the face of conversions of private medical institutions in the United States,the federal and state governments of the United States have developed corresponding laws and policies to adapt to the situation.The paper made an analysis of the profile and causes of the changed business nature of such institutions,and an introduction to the laws on which such change took place,the roles and responsibilities of government departments,the assets disposal and tax exemption status as well as the pricing policies.

Objective To evaluate the clinical application value of local injections of carbon nanoparticle in gastrectomy of stomach neoplasms.Methods Forty cases of stomach neoplasms with local injections of carbon nanoparticle in gastrectomy of stomach neoplasms were as experimental group,and 40 cases of stomach neoplasms with conventional gastrectomy of stomach neoplasms were as control group.The number of removed tiny lymph node and transferred tiny lymph node was compared.Results There was significant difference in the average number of removed tiny lymph node N1,N2,N3 between experimental group and control group (5.120 ± 0.455 vs.2.900 ± 0.245,3.890 ± 0.367 vs.1.750 ± 0.256,1.790 ± 0.224 vs.0.590 ± 0.054)(P ＜ 0.01).There was significant difference in the average number of transferred tiny lymph node N1,N2,N3 between experimental group and control group (1.090 ±0.087 vs.0.430 ± 0.044,0.550 ± 0.052 vs.0.340 ± 0.027,0.410 ± 0.044 vs.0.130 ± 0.013)(P ＜ 0.05).There was no significant difference in postoperative complications,mortality and length of hospital stay(P＞ 0.05).Conclusion Carbon nanoparticle in gastrectomy of stomach neoplasms is a simple,safe,easy method,and it has certain supplementary role in conventional gastrectomy of stomach neoplasms.

Objective To evaluate the safety and validity of an early steroid withdrawal protocol including cyclosporine (CsA) and mycophenolate mofetil (MMF) in middle aged and elderly renal transplant patients. Methods Between September 2000 and April 2008, the prospective, randomized study design was used in 80 middle aged and elderly renal transplant patients. Steroid withdrawal group (n=39) with primary cadaveric kidney transplants received a protocol consisting of CsA 4～6 mg·kg~(-1)·d~(-1) beginning at postoperative day 3, MMF 0. 75 g twice a day from the next postoperative day, and methylprednisolone (MP) 500 mg daily from day 0 to 3. Then prednisone (Pred) 20 mg daily was gradually tapered and withdrawn after postoperative day 30. Conventional steroid treatment group (control group, n=41) received a regimen consisting of CsA, MMF and MP, and Pred 20 mg daily. Pred was tapered to 5 mg daily over a period of 6 months, then maintained thereafter. Outcome parameters were patient and graft survival rates, renal function, acute rejection ( AR), arterial hypertension, hyperlipidemia or diabetes mellitus, weight gain and infection. Results The incidence of AR in the steroid withdrawal group was similar to the control group (23. 1% vs. 19. 5%, χ~2=0. 15,P>0. 05). Patient survival rates at 12, 24, 36 months were 97. 4%, 94. 8% and 88.0% in the steroid withdrawal group and were 97.6%, 97.6 and 87.8% in the control group, respectively (χ~2=0. 17, P>0. 05). And graft survival rates were 94. 9%, 88. 6% and 83. 7% in the steroid withdrawal group and were 95. 1%, 91. 5% and 79. 5% in control group, respectively (χ~2 = 0.07, P>0. 05). Conclusions In middle aged and elderly renal transplant patients, early steroid withdrawal is feasible and may not significantly increase the risk of acute rejection episodes.

Objective To discuss the clinical application of noninvasive positive pressure ventila-tion for patients with acute respiratory distress syndrome (ARDS) as a result of cytomegalovirus (CMV) interstitial pneumonia after renaltransplantation. Methods There were 371 renal transplan-tation from March 2003 to October 2006, 27 patients were diagnosed as CMV pneumonia postopera-tion. Ten patients were treated with noninvasive positive pressure ventilation within the 11 patients who aggravated to ARDS. The clinical data of before and after mechanical ventilation were reviewed. Results Among patients received noninvasive positive pressure ventilation, 1 died of complication. Seven patients were cured by noninvasive positive pressure ventilation. Significant difference of the physiological index presented between the 7 patients cured with noninvasive positive pressure ventila-tion before and after the use of ventilation(P<0.05), and significant difference of the renal function also existed(P<0.05). Conclusion The major value of noninvasive positive pressure ventilation is to correct the hypoxemia.

BACKGROUND:Studies have shown that cytokine inhibitor pirfenidone can inhibit biological activity of fibroblasts by regulating a variety of cytokines. It has made good progress in the research and application of anti-fibrosis of internal organs, but the effect and mechanism for hypertrophic scars and skin fibroblasts are unclear. OBJECTIVE:To investigate the effect of pirfenidone on human hypertrophic scar fibroblasts. METHODS:Human hypertrophic scar fibroblasts were cultured using tissue culture method. Passages 3-6 cel s grew wel in the logarithmic growth phase were col ected. Cel s were divided into the control group (0 g/L pirfenidone), 0.15, 0.3 and 1 g/L pirfenidone groups according to different mass concentrations. Cel s were intervened for 12, 36 and 48 hours. RESULTS AND CONCLUSION:MTT, reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay results demonstrated that compared with the control group, cel proliferation, transforming growth factorβ1 mRNA expression, types I and III col agen secretion were decreased in the 0.15, 0.3 and 1 g/L pirfenidone groups (P<0.05), and the decrease was most significant in the 1 g/L pirfenidone group (P<0.05). At 24, 48 and 72 hours after intervention, significant differences in inhibitory rate of cel proliferation and the secretion of types I and III col agen were detected among 0.15, 0.3 and 1 g/L pirfenidone groups (P<0.05). Results confirmed that pirfenidone apparently inhibited the secretion of col agen of hypertrophic scar fibroblasts cultured in vitro, transforming growth factorβ1 expression and cel proliferation and viability.

Objective To investigatethe quality of life of patients with oral cancer in different period in a hospital, and to explore the impact of patients' psychological status on their quality of life. Methods 50 cases of oral cancer patients in our hospital were investigated in this study by Convenience sampling method. The scale of the hospital anxiety and Depression Scale (HADS, the Japanese version), the quality of life of cancer patients were measured by the scale (FACT-G); the functional evaluation of tumor therapy- head and neck questionnaire (FACT-H&N). Results The comparison of HADS score between patients before and after surgery showed that the improvement of mental status was not obvious in the postoperative patients.The scores of HADS between patients before surgery and after hospital showed that the improvement of mental status was obvious (t=-2.809, P=0.01; t=-3.828, P=0.003). There were significant differences in HADS anxiety and depression-related factors between different periods (F=7.644,P=0.001;F=6.442,P=0.002);Before surgery,patients with low anxiety and depression had higher scores in both emotional and physical functional dimensions, and the difference between the two groups was statistically significant (t=7.882,5.847,6.870,7.262, P<0.05 or 0.01). The scores of the two groups were higher in the whole life quality dimension after surgery,and the difference between the two groups was statistically significant(t=3.640-7.931,P<0.01 or 0.01).There were significant differences in body function and psychological function scores between different periods(F=8.569, P=0.000; F=10.250, P=0.003). Conclusions Oral cancer patients have a higher level of anxiety and depression before and after surgery, and psychological status of patients with a certain impact on quality of life, it should be targeted for individual characteristics of patients with targeted care measures to improve the psychological status of patients,thereby improving the quality of life of patients.

Objective:To investigate the status of secondary victim effect of nurses in tertiary hospitals after adverse events and analyze its influencing factors.Methods:This study was a cross-sectional study. The convenient sampling method was used to select nurses from tertiary hospitals in Beijing, Shanxi and Shandong Province from October to December 2019 as the survey objects. The general information questionnaire and the Second Victim Experience and Support Tool (SVEST) were used to investigate them. Through single factor analysis of variance and multiple linear regression analysis, influencing factors of second victims of nurses were analyzed. A total of 2 163 online questionnaires were distributed and 2 040 were effectively recovered, with an effective recovery rate of 94.3%.Results:Among them, 813 nurses reported adverse event experiences, which were included in the study analysis. The total score of second victim effect of 813 nurses was (58.01±15.32) . Among the average scores of each dimension item, the score of "psychological distress" was the highest and the score of "management support" was the lowest, which were respectively (3.20±1.04) and (2.02±0.90) . The results of univariate analysis showed that there were statistically significant differences in the total scores of the second victim effect of nurses in different departments, marital status, professional title and employment nature ( P<0.05) . The results of multiple linear regression analysis showed that department, professional title and employment nature were the influencing factors of the second victim effect of nurses. The employment nature, marital status and departments had effects on the physiological distress of the second victim, and adverse event classification and departments had an effect on the psychological distress of second victims. Conclusions:The occurrence of adverse events has a moderate impact on the second victim of nurses in tertiary hospitals. Nurses are faced with more serious psychological distress, and the support they feel mainly depends on "management support", which is affected by many factors. Hospital administrators should take a positive view of the second victim effect, pay attention to the physical and mental health of nurses experiencing the role of second victim and provide effective support for different influencing factors.

Objective:To investigate the clinical characteristics in older adult patients with sepsis and heart failure, and to analyze the influential factors of prognosis.Methods:Eighty-eight older adult patients with sepsis and heart failure who received treatment at Lishui Central Hospital from January 2020 to December 2022 were retrospectively included in the heart failure group. Eighty-eight older adult patients with sepsis, who did not have heart failure, were selected in a 1:1 ratio to form a non-heart failure group. Based on their survival status during hospitalization, the patients in the heart failure group were divided into two subgroups: the survival group and the death group. Logistic regression analysis was performed to identify the risk factors associated with the development of heart failure and adverse disease outcomes in older adult patients with sepsis.Results:There were no statistically significant differences in sex, smoking history, alcohol consumption history, history of hypertension, and history of diabetes between the heart failure group and the non-heart failure group (all P > 0.05). However, the proportion of patients aged 75 years or older in the heart failure group was 52.27% (46/88), which was significantly higher than the proportion in the non-heart failure group [34.09% (30/88), χ2 = 5.93, P < 0.05]. The proportion of patients with respiratory system infections in the heart failure group was 53.41% (47/88), which was significantly higher than the proportion in the non-heart failure group [29.55% (26/88), χ2 = 10.37, P < 0.05]. Logistic regression analysis showed that advanced age and respiratory system infections are independent risk factors for the development of heart failure in patients with sepsis. Among patients with sepsis and heart failure, 45 survived and 43 died, resulting in a mortality rate of 48.86%. The average age of patients in the death group was (76.27 ± 4.14) years, which was significantly higher than that in the survival group [(72.29 ± 4.06) years, t = 4.55, P < 0.05]. The brain natriuretic peptide level and the Acute Physiology and Chronic Health Evaluation II (APACHE II) score in the death group were (636.70 ± 70.29) pg/mL and (31.93 ± 3.08) points, respectively, both of which were significantly higher than those in the survival group [(552.80 ± 54.66) pg/mL, (27.06 ± 3.80) points, t = 6.27, 6.59, both P < 0.05]. The lactate clearance rate and serum albumin level in the death group were (13.63 ± 4.84)% and (26.09 ± 4.77) g/L, respectively, both of which were significantly lower than those in the survival group [(19.94 ± 5.07)%, (30.55 ± 5.17) g/L, t = 5.97, 4.20, both P < 0.05]. Logistic regression analysis showed that in patients with sepsis and heart failure, advanced age, elevated serum brain natriuretic peptide levels, and high APACHE II scores are risk factors for poor prognosis and death. A high lactate clearance rate at 24 hours and elevated serum albumin levels are protective factors for survival. Conclusion:Advanced age and respiratory system infections increase the risk of heart failure in patients with sepsis. Advanced age, elevated brain natriuretic peptide levels, and high APACHE II scores are associated with an increased risk of death in these patients. High lactate clearance rates and elevated serum albumin levels are indicative of a reduced risk of death in patients with sepsis.

OBJECTIVETo investigate the relationship between two polymorphisms immediately upstream of the cyclooxygenase 2 (COX2) gene and preeclampsia in a South West Han Chinese population.

METHODSBlood samples from 205 patients with preeclampsia and 276 normal pregnant women as controls from Han Chinese in Chengdu area were analyzed by polymerase chain reaction-restriction fragment length polymorphisms.

RESULTSG and A allele frequencies for -1195G>A site were 48.54% and 51.46% in the patient group, respectively, and 40.40% and 59.60% in the control group, respectively. G and C allele frequencies for -765G>C site were 94.15% and 5.85% in the case group, respectively, and 94.38% and 5.62% in the control group, respectively. The AA genotype and variant A allelic frequencies of the -1195G>A SNP were significantly lower in patients with preeclampsia than in the control group (P<0.05), and the odds ratio for the risk of preeclampsia was 0.665 (95% CI: 0.444-0.982) in women homozygous for the variant COX2 A allele ( x²=4.233, P=0.047). The genotype and allele frequencies of the -765G>C polymorphism in patients with preeclampsia and controls showed no significant differences (P>0.05). Additional subgroup analyses (mild vs severe preeclampsia) of the two polymorphisms failed to reveal significant correlation for either genotypic or allelic frequencies. Furthermore, there was no significant association between the polymorphisms and blood pressure levels in the patient or control groups.

CONCLUSIONCOX2 -1195A homozygosity is associated with a decreased risk for preeclampsia in a South West Han Chinese population. On the other hand, the -765G>C polymorphism has no effect.
