Objective To evaluate the therapeutic effect of lentinan combined with conventional antituberculous therapy in women with pelvic tuberculosis.Methods A total of 90 women with pelvic tuberculosis were enrolled and recruited into a control group and a treatment group by random number table,45 in each group.The control group was treated with anti-tuberculosis program (2HRZE/4HRE),while the treatment group was treated with lentinan tablets on the basis of the control group.Both groups were treated for 6 months.Serum levels of carbohydrate antigen 125 (CA125) and erythrocyte sedimentation rates (ESRs) were determined before and after treatment,and the therapeutic effect was evaluated.Results After treatment,the serum CA125 level (28.61 ± 9.08 U/ml vs.39.72 ± 12.13 U/ml;t=4.919,P＜0.01) and the ESR (36.13 ± 8.33 mm/h vs.41.35 ± 12.45 mm/h;t=2.338,P＜0.05) in the treatment group were significantly lower than those in the control group.The negative rate of serum CA125 after treatment than before treatment in the treatment group (93.3％ vs.20.0％;X2=46.335,P＜0.01) and the control group (82.2％ vs.8.9％;X2=37.396,P＜0.01);but there was no difference in negative rate of serum CA125 after treatment between two groups (X2=1.6571,P=0.198).The total effective rate in the treatment group was significantly higher than that in the control group (93.3％ vs.77.8％;X2=4.406,P=0.036).Conclusion Lentinan combined with conventional antituberculous therapy is effective in treatment of pelvic tuberculosis in women.

Objective: To assess the relationships between nutritional risks, nutritional support, and doctors' knowledge related to nutritional risks. Methods: 217 pre-operative patients and 41 doctors in the same general surgical wards were surveyed by using NRS2002 and self-developed questionnaires in a Beijing hospital. Results: The overall prevalence of pre-operative nutritional risks was 15.7%. Patients with gastrointestinal and/or malignant diseases had higher risks than others(P values were both less than 0.001). The nutritional support rates were 14.7% among patients with nutritional risks, and 2.2% among those without risks. The EN: PN ratio was 1∶ 2. A majority of doctors had misconceptions in nutritional risk screening and the effectiveness of nutritional supports. Their clinical practices were not consistent with their knowledge. Related trainings were required. Conclusions: Patients with gastrointestinal and/or malignant diseases have higher possibilities of nutritional risks. The nutritional supports rates are generally low. Doctors' knowledge related to nutritional risk screening is insufficient. More training opportunities are suggested to enhance the application of NRS2002 and appropriate nutritional supports.

Objective To evaluate the preoperative undernutrition, nutritional risks, and nutritional support in general surgical wards. Methods The nutritional risks of 217 new in-patients in general surgical wards in a Beijing-based hospital were assessed using nutrition risk screening 2002 ( NRS 2002 ) and the medical records were reviewed. Results The overall prevalence of preoperative undernutrition and nutritional risks was 7.4% and 14.7% respectively, most of which occurred in patients with gastrointestinal diseases and malignant diseases. Nutritional supports were provided to 18.8% of patients with undernutrition, 12.5% of patients with nutritional risks,3.0% of patients without undernutrition, and 2.7% of patients without nutritional risks. The enteral nutrition:The application of nutritional support should be further improved in general surgical wards.

Objective:To investigate the correlation between white matter hyperintensities (WMHs) and stroke etiology classification in patients with acute isolated penetrating artery territory infarction.Methods:Patients with first-ever acute isolated penetrating artery territory infarction admitted to the Department of Neurology, the Affiliated Hospital of Xuzhou Medical University from January 2017 to May 2020 were enrolled retrospectively. According to the Chinese Ischemic Stroke Subclassification (CISS) system, they were divided into large artery atherosclerosis (LAA) and perforating artery disease (PAD). According to the distribution of infarcts, they were divided into lenticulostriate artery (LSA) territory infarction and paramedian pontine artery (PPA) territory infarction. The demographics, vascular risk factors, baseline clinical data, WMHs location, and Fazekas Scale scores were documented. Multivariate logistic regression analysis was used to identify the independent influencing factors of stroke etiology classification. Results:A total of 440 patients with acute isolated penetrating artery territory infarction were enrolled, including 120 (27.3%) in the LAA group, and 320 (72.7%) in the PAD group; 213 (48.4%) with LSA territory infarction, and 227 (51.6%) with PPA territory infarction. The proportion of patients with total Fazekas score 3-6 and periventricular WMHs (PWMHs) score 2-3 in the PAD group was significantly higher than those in the LAA group (all P<0.05). In patients with LSA territory infarction, the proportion of the patients with hypertension, WMHs total Fazekas score 3-6 and PWMHs score 2-3 in PAD subgroup was significantly higher than those in the LAA subgroup, while the proportion of the patients with hyperlipidemia was significantly lower than that in LAA subgroup (all P<0.05). In patients with PPA territory infarction, the levels of low-density lipoprotein cholesterol and homocysteine in the PAD subgroup were significantly lower than those in the LAA subgroup. Multivariate logistic regression analysis showed that PWMHs score 2-3 was an independent correlation factor of PAD (odds ratio [ OR] 2.220, 95% confidence interval [ CI] 1.085-4.541; P=0.029). In patients with LSA territory infarction, hyperlipidemia was independently correlated with LAA ( OR 0.432, 95% CI 0.192-0.972; P=0.042), and PWMHs score 2-3 was independently correlated with PAD ( OR 3.846, 95% CI 1.193-12.397; P=0.024). In patients with PPA territory infarction, higher low-density lipoprotein cholesterol ( OR 0.660, 95% CI 0.494-0.883; P=0.005), homocysteine ( OR 0.958, 95% CI 0.930-0.987; P=0.005) and C-reactive protein ( OR 0.987, 95% CI 0.977-0.997; P=0.008) were independently correlated with LAA. Conclusions:WMHs are common in patients with acute isolated perforating territory infarction caused by LAA and PAD, and more severe PWMHs suggest that PAD is more likely to be the cause of the acute isolated perforating territory infarction, especially in patients with LSA territory infarction.

Objective To investigate the expression of osteopontin ( OPN) in epithelial ovarian cancer tissue and its prognostic value. Methods The immunohistochemistry method was used to detect the expression of OPN in 64 cases of epithelial ovarian cancer tissue, and 20 cases with ovarian benign tumors and 10 normal ovarian tissues as well. The relationship between the OPN expression and clinical pathological characteristics and its prognostic value were analyzed statistically. Results The positive expression of OPN case was confirmed in 52 cases in 64 epithelial ovarian cancer. The expression level of OPN in epithelial ovarian cancer tissue was significantly higher than that in benign ovarian tumor and normal control (P <0. 01). The OPN expression in epithelial ovarian cancer tissues was associated with the pathological grading, lymphatic metastasis and production of ascites. The survival time is longer in OPN negative patients than the positive group. Conclusions OPN plays an important role in the tumorgenesis and development of epithelial ovarian cancer and correlates with its prognosis.

Objective To analyze the clinical and molecular features of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infection in neonates and to investigate their antibiotic resistance profiles.Methods A total of 35 invasive CA-MRSA strains were collected from six hospitals in 2014.Multilocus sequence typing (MLST), staphylococcal cassette chromosome mec (SCCmec) typing and spa typing were used to analyze these isolated CA-MRSA strains.In vitro antibiotic susceptibilities of those strains to 15 antibiotics were analyzed by using agar dilution method.Results Up to 88.6% patients were late-onset infection and septicemia (24, 68.5%) was the most common infection among the 35 cases.A total of 16 patients (45.7%) suffered from complications.Caesarean section and premature birth were risk factors for invasive CA-MRSA infection.ST59-MRSA-SCCmecⅣa-t437 (14, 40%) was the most predominant CA-MRSA clone, followed by ST59-MRSA-SCCmecⅤ-t437 (13, 37.1%).The incidence of severe complications caused by ST59-MRSA-SCCmecⅤ-t437 was higher than that caused by ST59-MRSA-SCCmecⅣa-t437 (P<0.05).Up to 85.7% of the isolated CA-MRSA strains were multidrug-resistant strains.Conclusion This study shows that neonatal invasive CA-MRSA infections mainly result in septicemia and are often accompanied by complications and involve multiple organs.Multidrug-resistant CA-MRSA strains are prevalent in neonates.ST59-MRSA-SCCmecⅣa-t437 is the predominant clone causing neonatal invasive CA-MRSA infection.

Objective To detect the expression levels of interleukin (IL)-25 and IL-33 in peripheral blood of patients with chronic urticaria.Methods Ninety-three patients with chronic urticaria were included in this study along with 30 healthy individuals.All the patients were treated with loratadine for four weeks.Blood samples were collected from the healthy controls and patients before and after the four-week treatment.Enzyme-linked immunosorbent assay (ELISA) was performed to detect the serum levels of IL-25 and IL-33.The relationship between the expression levels of the two cytokines and urticaria severity was analyzed.Results The serum levels of IL-25 and IL-33 in the patients before treatment were significantly higher than those in the healthy controls (IL-25,139.86 ± 28.48 vs.114.41 ± 34.00 ng/L,P ＜ 0.01; IL-33,91.95 ± 21.88 vs.79.80 ± 30.72 ng/L,P ＜ 0.05),and positively correlated with the severity of urticaria (r =0.38,0.42,respectively,both P ＜ 0.01).After four weeks of treatment,clinical improvement was observed in 81.72％ of these patients with a significant decrease in the serum IL-25 level (116.48 ± 21.94 vs.139.86 ± 28.48 ng/L,P ＜ 0.01),but no obvious changes in the serum IL-33 level (90.88 ± 20.62 vs.91.95 ± 21.88 ng/L,P ＞ 0.05) compared with those before treatment.Conclusions The expressions of IL-25 and IL-33 are elevated in peripheral blood of patients with chronic urticaria,and positively correlated with the severity of urticaria.

BACKGROUND:There is lack of effective diagnostic methods for early knee osteoarthritis. Proteomics refers to the large-scale experimental analysis of proteomes from the overal level of intracel ular protein compositioon, expression and modification, based on which, we can understand protein-protein interaction and relationship, thereby revealing protein functions and cel activity patterns. OBJECTIVE:To apply the isobaric tags for relative and absolute quantitation (iTRAQ) to identify proteins differential y in serums of osteoarthritis Kel gren-Lawrence classification at each stage, and to find out potential molecular markers at each stage of osteoarthritis. METHODS:Sixty patients with knee osteoarthritis were enrol ed, and according to Kel gren-Lawrence (K-L) grading, they were subdivided into K-L 0, II and IV groups. There were 10 males and 10 females randomly selected in each group. Proteins differential y regulated in serums were identified by the stable isotopes 116, 117, 118 of the iTRAQ labeled, reversed-phase column separation, mass spectrometry and Swissport database search, after the serums were subjected to high abundance proteins depletion. Final y, we analyzed the proteins identified by using bioinformatics software. RESULTS AND CONCLUSION:Total y 169 proteins were identified through iTRAQ peptides experiments of different sample tags, Q-star mass spectrum identification and MASCOT library search. 153 proteins were identified as K-L 0 to K-L IV, 153 proteins were identified as K-L 0 to K-L II, and 145 proteins were identified as K-L II to K-L IV. iTRAQ technology may help to identify novel serum markers for early diagnosis of knee osteoarthritis, indicating iTRAQ technology for proteomics serum biomarkers of osteoarthritis study has good application prospect.

Objective To apply electrical impedance tnmography that is a new evaluation ap-proach to monitor the development of retroperitoneal injury. We used retroperitoneal inject blood model in pigs to study the feasibility on monitoring retroperitoneal bleeding and to provide premise in theory and practice for clinical application. Methods Five pigs were used on the experiment. We insert a vessel into the retroperitoneal and inject blood to simulate retroperitoneal bleeding. Sixteen electrodes were atta-ched on the abdominal region circumference of pigs and used for electrical current injection and surface voltage measurement. Then the monitoring images were performed by electrical impedance tomography. Results The images of electrical impedance tomography retroperitoneal inject blood model of five pigs were clear, the minimal impedance scale was decreasing significantly as the bleeding volume increasing and the images were changed significantly too. The computerized tomography and the dissecting results confirmed the blood was limited in retroperitoneal. Conclusions The establishments of pigs retroper-itoneal inject blood model was successful. The images of electrical impedance tomography retroperitoneal inject blood model were clear with significant contrast. It's feasible to use electrical impedance tomography system to monitor the retroperitoneal bleeding. This technique may become a useful tool for monitoring ret-roperitoneal injury in intensive care patients.

Objective To analyze of the risk factors for persistent pulmonary hypertension of newborn(PPHN) after resuscitation in neonatal asphyxia.Methods Total 92 cases of PPHN in neonatal asphyxia were admitted in NICU,Beijing Children's Hospital Affiliated to Capital Medical University from Jan.2009 to Dec.2013 as PPHN group.According to patients condition,to case-control study method were randomly selected 92 cases without PPHN in neonatal asphyxia in the same period as control group.Except for other serious complications with PPHN,such as respiratory distress syndrome,meconium inhalation,pulmonary hemorrhage,neonatal severe pulmonary infection and diaphragmatic hernia.Apgar score and rescue measures after asphyxia based on the newborn perinatal questionnaire and body temperature,blood sugar,arterial blood gas and echocardiography on admission were recorded.Results Respiratory treatment of PPHN group and control group were 71 cases (77.2％) vs 28 cases (30.4％),respectively.There was significant difference (x2 =6.380,P =0.012).On admission,mean arterial pressure [(32.36 ± 11.52) mmHg],temperature [(34.3 ±0.28) ℃],blood sugar [(2.56 ±0.77) mmol/L] and arterial blood pH value (7.16 ±0.21) in PPHN group were lower than those of the control group [(38.55 ± 9.18) mmHg,(36.5 ± 0.71) ℃,(3.46 ± 0.53) mmol/L,7.21 ±0.14].For mild and severe asphyxia cases in the PPHN group,blood gas and pulmonary hypertension had no statistical difference after rescucitation in the delivery hospital.Conclusions Acidosis,hypothermia,low blood pressure and hypoglycaemia after resuscitation in neonatal asphyxia are major risk factors for genesis of PPHN.This research shows that rescue after asphyxia timely,early and respiratory support effectively,monitoring closely,treatment of hypoglycemia and hypothermia,correct acidosis and maintain blood pressure can play a positive role in decreasing the morbidity of PPHN in neonatal asphyxia.
