Objective:To investigate the difference of clinical characteristics of children and adults with brucellosis osteoarthritis in Yinchuan, Ningxia.Methods:The clinical data of patients with brucellosis osteoarthritis who were diagnosed in General Hospital of Ningxia Medical University from January 2009 to September 2019 were collected retrospectively. According to age, the patients were divided into two groups: children (0-14 years old, 50 cases) and adults (≥15 years old, 236 cases). Epidemiological characteristics, clinical manifestations and laboratory examination results of the two groups were compared and analyzed.Results:Among children, 39 were males and 11 were females, school age children (8-14 years old, 25 cases) were more common; among adults, 179 were males and 57 were females, middle-aged and elderly people (46-65 years old, 128 cases) were more common. The peak incidence of both groups was from March to August (39 children and 142 adults). In the two groups, a total of 266 patients (40 children and 226 adults) were recorded with a history of exposure, of which 226 patients (28 children and 198 adults) had contacted with cattle, sheep and other live animals. In clinical manifestations, compared with children, adults had higher incidences of low back pain [38.00% (19/50) vs 63.98% (151/236)], hyperhidrosis [6.00% (3/50) vs 30.08% (71/236)] and fatigue [8.00% (4/50) vs 34.75% (82/236)], and lower incidences of single joint pain [70.00% (35/50) vs 19.49% (46/236)], fever [72.00% (36/50) vs 49.15% (116/236)], and lymph node enlargement [30.00% (15/50) vs 2.54% (6/236)], and the differences were statistically significant ( P < 0.05). Among children, the knee joint involvement (62.00%, 31/50) and hip joint involvement (42.00%, 21/50) were more common, but spinal involvement was not found; while among adults, spinal involvement (55.51%, 131/236) was the most common. The incidences of elevated white blood cell count [18.00% (9/50) vs 6.36% (15/236)], elevated percentage of lymphocytes [82.00% (41/50) vs 27.12% (64/236)], elevated platelet [24.00% (12/50) vs 8.90% (21/236)], elevated aspartate aminotransferase [64.00% (32/50) vs 30.08% (71/236)], elevated alanine aminotransferase [38.00% (19/50) vs 20.76% (49/236)] and anemia [42.00% (21/50) vs 16.53% (39/236)] in children were higher than those in adults; the incidences of elevated percentage of neutrophils [0 (0/50) vs 9.75% (23/236)], hypoalbuminemia [2.00% (1/50) vs 14.41% (34/236)], low sodium [2.00% (1/50) vs 10.17% (24/236)], elevated C-reactive protein [50.00% (25/50) vs 77.12% (182/236)] in children were lower than those in adults, and the differences were statistically significant ( P < 0.05). The positive rate of blood culture in children (65.22%, 30/46) was higher than that in adults (40.54%, 60/148), and the difference was statistically significant ( P < 0.05). Conclusions:There are differences in clinical characteristics between children and adults with brucellosis osteoarthritis in Yinchuan, Ningxia. In particular, there is a significant difference between children and adults in the location of bone and joint involvement.

OBJECTIVE: To investigate the factors influencing sterility in males undergoing routine sperm inspection by masturbation. METHODS: Scales for demographic data, self-compiled infertility questionnaire, Symptom Checklist-90 (SCL-90) , and sexual life subscale of Olson Marital Quality Questionnaire (ENRICH) were assessed in 220 cases of sterility in males who had undergone sperm examination after ejaculation. RESULTS: The total SCL-90 scores and the factor scores of anxiety, phobia, somatization, obsessive compulsive behavior, interpersonal-sensitivity, hostility, and depression were significantly higher than the norm (P<0.05). The total SCL-90 score of 69 males was higher than 160, implying that 31.36% of the sterile males had negative emotions. The total score was related to wife's attitude, semen collecting room, ejaculation situation, and the general state of sexual life. The ejaculation situation was subjected to a multivariate linear regression model. CONCLUSION About 1/3 of males with sterility problems undergoing routine semen examination by masturbation have negative emotions such as anxiety, phobia, somatization, and interpersonal sensitivities. The defective ejaculation may be the influential factor at the stage.

Objective:Based on the clinical indicators of severe community-acquired pneumonia in emergency department, the early warning indicators of critical condition were constructed.Methods:The general information, vital signs before entering ICU, laboratory indexes and the survival rate in 30 days of 118 patients with community-acquired pneumonia were retrospectively collected in the emergency care unit of Peking Union Medical College Hospital from January to December 2018. The indexes of death patients (24 cases) and alive patients (98 cases) underwent comparative analysis, using ROC curve to predict the clinical outcome and reliable parameters of emergency patients with community-acquired pneumonia. The best cutoff value was determined according to Youden index and then undergoing multiple factors Logistic stepwise regression analysis. Then early warning model of critical degree was finally built.Results:Eleven indicators were used to predict the criticality of patients with acute community-acquired pneumonia, including AVPU (alert, voice, pain, unresponsive) score, Glasgow Coma Scale(GCS), heart rate, pulse oxygen saturation (SpO 2), fraction of inspiration O 2, oxygenation index,potential of hydrogen, blood potassium (K +), bilirubin, urea nitrogen, and C reactive protein, the optimal cutoff values were 2 points, 8 points, 91 times per minute, 0.94, 41%, 81.20%, 7.38, 4.0 mmol/L, 10.90 μmol/L, 2.23 mmol/L, and 41.5 mg/L. Multiple Logistic stepwise regression showed that the independent factors for predicting death were GCS score, SpO 2 and urea nitrogen, and the predictive ability of the early-warning model was 83.7%. Conclusions:GCS score, SpO 2 and urea nitrogen are effective early warning indicators for the severity of severe community-acquired pneumonia in emergency department, which are conducive to the rapid and efficient early identification and treatment of critically ill patients. Therefore, they are worthy of promotion and application in clinical practice.

Inflammatory response is an important immune mechanism of the body, formyl peptide receptor (FPR) 1 is a pattern recognition receptor expressed in immune cells, and its binding with ligands is the basis for immune cells to realize various physiological functions in infectious inflammation. FPR1 plays an important role in inflammatory response, and changes in amino acids caused by its gene polymorphism affect a variety of diseases. Plague is an inflammatory disease caused by Yersinia pestis. Yersinia pestis, its pathogen, has a strong ability of immune escape and attacks on host immune cells. In this paper, FPR structural characteristics, expression and distribution, FPR1 gene polymorphism, ligand and its relationship with plague are reviewed, with a view to further understanding the role of FPR1 in the occurrence and development of plague.

Objective: To assess the effectiveness of radiofrequency ablation (RFA) in the treatment of multiple pregnancies. Methods: In this retrospective study, 84 cases (total 174 fetuses) of complex monochorionic pregnancies treated with RFA for selective fetal reduction were analyzed. All cases were managed in the Guangdong Women and Children Hospital from January 2015 to January 2018. Indications for offering RFA, details of the procedure and pregnancy outcomes were collected and analyzed. Results: (1)The rate of miscarriage and fetal intrauterine death was 21% (18/84), termination of pregnancy because of fetal malformation or oligohydramnion occurred in 10% (8/84) of cases. Total live birth rate was 69% (58/84) and the gestation age at delivery was (35.0±3.0) weeks. (2) The live birth rate of twin reversed arterial perfusion sequence (TRAPS) was the lowest (6/11), followed by twin to twin transfusion syndrome (TTTS; 66%, 27/41), structural or genetic abnormalities of one fetus in monochorionic twin pregnancy (10/14), triplet pregnancy reduction (4/6) and selective intrauterine growth restriction (sIUGR) (11/12). (3) The live birth rate was 67% (20/30) in stage Ⅲ of TTTS and 7/11 in the stage Ⅳ of TTTS (P>0.05). The average gestational age was (33.6±3.0) weeks in stage Ⅲ of TTTS compared with (36.5±2.4) weeks in the stage Ⅳof TTTS (P<0.05). Conclusions RFA appears to be a reliable option for selective fetal reduction in monochorionic multiple pregnancies. The indication of RFA is an influencing factor on its pregnancy outcomes. Type Ⅱand type Ⅲ sIUGR may choose this technique as a priority. Compared with stage Ⅲ of TTTS, the live birth rate and the gestation age at delivery in stage Ⅳ of TTTS, there are no significant differences.

OBJECTIVETo investigate the reversing effects of curcumin on hepatocellular carcinoma drug resistance Bel7402/5-Fu cell line.

METHODSThrough the exposure to gradual increased concentrations of 5-fluorouracil (5-Fu), the cell line Bel7402 was induced to establish a multi-drug resistant sub-cell line Bel7402/5-Fu. The sensitivity to 6 chemotherapeutics of Bel7402 and Bel7402/5-Fu were detected using methyl thiazolyl tetrazolium (MTT) assay. The 50% inhibitory concentration (IC50) and resistant index (RI) were calculated. The differences of the inhibition ratio of Bel7402/5-Fu by curcumin, 5-Fu, curcumin combined with 5-Fu were detected using MTT assay. The effects of curcumin, 5-Fu, curcumin combined with 5-Fu on the Bel7402/5-Fu apoptosis were detected using flow cytometry.

RESULTSThe Bel7402/5-Fu cell line showed multi-drug resistance (MDR) to various chemotherapeutics, with the highest RI shown of 5-Fu (being 109.55 +/- 14.30 times). The inhibition ratio of 5, 10, and 20 microg/mL curcumin combined with 5-Fu (50% IC50) was respectively 21.47% +/- 1.49%, 27.10% +/- 2.32%, and 59.37% +/- 2.45%. The Bel7402/5-Fu apoptosis ratio of 5, 10, and 20 microg/mL curcumin combined with 5-Fu (50% IC50) was 30.92% +/- 2.10%, 44.87% +/- 2.24%, and 50.36% +/- 2.58%, respectively, which was obviously higher than that of the curcumin group and the 5-Fu group. Besides, the apoptosis rate increased along with increased curcumin concentration in the range of 0 -20 microg/mL.

CONCLUSIONCurcumin could induce the apoptosis of Bel7402/5-Fu. Meanwhile, it showed favorable reversing effects on MDR.
