Alveolar echinococcosis is a kind of parasitic disease caused by Echinococcus multilocularis infecting the human body. It is characterized by tumor-like, invasive growth, serious disease and high fatality rate. Even though the number of patients is limited, they require life-long treatment because of the serious condition, many complications, and treatment difficulties. At present, there are three clinical treatment options for alveolar echinococcosis, including surgical treatment(radical hepatectomy, palliative resection, liver transplantation), intervention treatment(ultrasound or CT-guided intervention, endoscopic intervention), and anti-infective drug treatment. This article analyzes the advantages and disadvantages of the above-mentioned schemes, and provides a basis for correct selection of treatment methods for alveolar echinococcosis.

OBJECTIVE:To study risk factors for carbapenem-resistant Acinetobacter baumannii(CRAB)infection,and to provide reference for its clinical prevention. METHODS:In retrospective study,302 A. baumannii(AB)infection patients were collected from our hospital during Dec. 2012 to Jun. 2017. According to the results of drug sensitivity test,those patients were divided into CRAB group(116 cases)and non-CRAB group(186 cases). Risk factors for CRAB infection were analyzed by using univariate analysis. Multivariate Logistic regression analysis was performed for variables with significant difference between 2 groups. RESULTS:Univariate analysis showed that the factors of significant difference in 2 groups including patients suffering from septic shock(P=0.003),sepsis(P=0.000),combined with other infection(P=0.006),diabetes(P=0.029),malignant tumors(P=0.036),patients suffering from infection of other site except for pulmonary infection,intraabdominal infection and skin infection(P=0.009)before AB isolation,patients given carbapenems(P=0.002)and antifungal drugs 28 d before AB isolation(P=0.002). Multivariate Logistic regression analysis showed that the factors of significant difference in 2 groups including patients suffering from sepsis(P=0.033)or diabetes(P=0.011)before AB isolation. CONCLUSIONS:Independent risk factors for CRAB infection include patients suffer from sepsis or diabetes before AB isolation.

Background：Global Handwashing Day (GHD) is a handwashing promotion campaign organized by the Global Public-Private Partnership of Handwashing with Soap. In China, it has been promoted by the Chinese public health authorities, international organizations and multinational corporations through various channels including social media such as Sina Weibo, the leading Chinese microblogging site similar to Twitter. The objective of this study is to qualitatively assess Chinese social media users’ reactions to a health promotion campaign using Global Handwashing Day (GHD) 2012 as an example.Methods：We conducted a qualitative content analysis of 552 Weibo posts generated on GHD 2012 by Weibo users with 1000 or more followers with the Chinese keyword for “handwashing.” We categorized the Weibo posts into groups by keywords that frequently appeared in the data set. These groups were either exact reposts of an original post, or they conveyed similar information.Results：We observed the interconnections between traditional media and social media in handwashing promotion. Social media were found to serve as amplifiers of contents provided by traditional media. We observed the contextualization of global hygiene messages in a unique national social media market in China.Discussion：Our study showed that social media and traditional media are two interconnected arms of the GHD campaign in China. Our analysis demonstrated that public health campaigns in China can be evaluated using social media data. The themes and topics identified in this study will help public health practitioners evaluate future social media handwashing promotion campaigns.

Objective:To evaluate the long-term health-related quality of life (QOL) in pediatric patients with acute leukemia after hematopoietic stem cell transplantation (HSCT) and to analyze potential influence factors.Methods:Patients with acute leukemia aging 8-18 years who received HSCT in the Hematology Oncology Center of Beijing Children′s Hospital from June 2009 to June 2012 with more than 80 months survival postoperatively were recruited.All of them were subjected to a short-term QOL survey in 2013.PedsQL? Transplantation Module 3.0 in Chinese mandarin version was completed.QOL data and influence factors were analyzed.Results:Forty-one patients completed the questionnaires, involving 32 males and 9 females with the mean age of(14.29±2.72) years.The mean scores of overall long-term QOL after HSCT were above 75 (total scores: 100), which was above the average.The age, disease status before transplantation, donor sources, post-transplant complications and the parental education level were the influential factors for the long-term QOL in pediatric patients with acute leukemia at post-HSCT, which could affect a certain dimension in QOL.Conclusions:The overall long-term QOL of pediatric patients with acute leukemia who survived for more than 80 months at post-HSCT is acceptable, which is significantly better than the short-term QOL after 4 months of HSCT.The age, disease status before transplantation, donor sources, post-transplant complications and the education level of parents could affect a certain dimension of QOL.

Objective:To investigate the effect of Suhuang Zhike Capsule on airway inflammation in patients with acute episode of allergic rhinitis and asthma syndrome.Methods:Eighty patients with allergic rhinitis and asthma syndrome were admitted to North China University of Science and Technology Affiliated Hospital from June 2016 to September 2017.A prospective cohort study was carried out and randomly divided into treatment group and control group with 40 patients in each group.The control group was treated with conventional anti-inflammatory, expectorant and antiasthmatic therapy, while the treatment group was treated with Suhuang Zhike Capsule.The changes of nasal symptoms and asthma clinical symptoms in the two groups were compared before and after treatment, and the changes of nitric oxide in exhaled air, eosinophils in blood and induced sputum were measured.Results:Compared with the control group, there was no significant difference in the number of eosinophils in the exhaled nitric oxide, eosinophil count in blood and induced sputum before treatment in the treatment group ((161.45±4.67)×10 -9 vs.(163.12±4.56)×10 -9, (1.59±0.53)×10 9/L vs.(1.60±0.51)×10 9/L, (1.11±0.06)×10 9/L vs.(1.18±0.09)×10 9/L; t values were 0.10, 0.44, 1.75, respectively, all P>0.05). After treatment, the exhaled nitric oxide, eosinophil count in blood and induced sputum in the treatment group were significantly lower than those before treatment((30.86±5.54)×10 -9 vs. (161.45±4.67)×10 -9; (0.32±0.05)×10 9/L vs. (1.59±0.53)×10 9/L; (0.06±0.02)×10 9/L vs. (1.11±0.06)×10 9/L, t values were 91.32, 41.63, 51.77, respectively, all P<0.01). In the treatment group, the effective rate of nasal symptom control was 85.0% (34/40) significantly higher than 62.5% (25/40) in the control group (χ 2=5.23, P<0.05), and the effective rate of asthma clinical symptom control was significantly higher than that in the control group(90.0%(36/40), 72.5%(29/40), χ 2=4.02, P<0.05). Conclusion:Suhuang Zhike capsule can obviously improve the airway inflammatory response of patients with allergic rhinitis asthma syndrome in the acute attack stage, and the combination of conventional treatment plan is helpful to improve the curative effect.

Objective:To investigate the effects of intra-articular injection of exosomes derived from dental pulp stem cells from hu-man exfoliated deciduous teeth(SHED-EXO)on subchondral bone homeostasis in rat temporomandibular joint osteoarthritis(TMJ OA)process.Methods:36 male SD rats were randomly divided into 3 groups(n=12):control(CON),sodium iodoacetate(MIA)-induced TMJ OA(MIA),and SHED-EXO injection into TMJ OA(SHED-EXO)groups.At 2 and 6 weeks post-treatment,Micro-CT,Double labeling,TRAP staining,and immunohistochemical staining were employed to detect osteoclasts and osteoblasts in the subchondral bone.Additionally,the mRNA expression levels of ADAMTs5,IL-1β,OCN and OPG/RANKL were analyzed by qRT-PCR.Results:The MIA group exhibited significant bone loss and an enlarged bone marrow cavity.In comparison with the CON group,BV/TV and Tb.Th were lower(P＜0.001),while BS/BV,Tb.Sp,and Tb.N were higher(P＜0.01).Additionally,the bone formation rate within 5 days was low-er than that of the control group(P＜0.001).When compared to the MIA group,the SHED-EXO group showed a significant increase in bone morphology and bone mass.BV/TV and Tb.Th were increased(P＜0.01),while BS/BV,Tb.Sp and Tb.N were decreased(P＜0.05).The bone formation rate was higher(P＜0.01).Compared with both the control and treatment groups,the MIA group exhibited a significant increase in the number of osteoclasts in the subchondral bone(P＜0.01),along with a notable decrease in H-type blood vessels and OCN-positive areas(P＜0.01).Conclusion:Intra-articular injection of SHED-EXO can reg-ulate condylar subchondral bone homeostasis in TMJ OA of rats by promoting osteogenesis and inhibiting osteoclasts.

OBJECTIVETo investigate the interval time to canceration, clinicopathological characteristics and prognostic factors of carcinoma in remnant stomach (CRS) in patients with primary benign diseases or primary malignant tumors.

METHODSBased on the criteria of the definition of CRS proposed by Japanese Gastric Cancer Association in 2017, a retrospective analysis was conducted on clinicopathological characteristics of patients diagnosed with CRS at Peking University Cancer Hospital from March 1992 to March 2017. Between patients with primary benign diseases (CBS-B group) and primary malignant tumors (CBS-M group), continuous variables were compared using the Student's t-test or the Mann-Whitney U test; categorical variables were compared using the chi-square test or Fisher's exact test. Spearmen-Rho was used to examine correlation. Survival was estimated and compared using Kaplan-Meier methods. Cox proportional hazards regression was applied to identify independent prognostic factors. Area under ROC curve(AUC) was used to evaluate and compare prediction accuracy.

RESULTSA total of 89 patients were included in the study with a male: female ratio of 5.4 to 1.0. The male: female ratio in CRS-B (n=46) and CRS-M (n=43) group was 14.3 to 1.0 and 2.9 to 1.0 respectively with significant difference (χ=6.091, P=0.019). The interval time to canceration in CRS-B and CRS-M group was 342(36-576) months and 47(12-360) months respectively with significant difference (t=8.887, P=0.000). The interval time to canceration was correlated with the first operative procedure in CRS-B group (r=0.398, P=0.006), while interval time to canceration was correlated with the age at the first operation in CRS-M group (r=0.337, P=0.027). After differentiating the pathological findings of the first operative sample and the second operative sample, 27 patients presented recurrence and 15 patients had new cancer, and the corresponding interval time to canceration was 46(12-132) months and 60(12-360) months respectively with significant difference (t=5.652, P=0.023). In CRS-B group, location of stump carcinoma in gastric intestinal anastomosis, gastric anastomosis, and non-anastomosis area was found in 60.9%(28/46), 23.9%(11/46) and 15.2%(7/46) respectively, and the corresponding percentage in CRS-M group was 39.5%(17/43), 16.3%(7/43) and 44.2%(19/43) respectively without significant difference (χ=4.726, P=0.096). Among 77 patients with radical gastrectomy, the overall surgical complication rate was 20.8%(16/77), including 8 cases of infection and 7 cases of respiratory system diseases. The 3-year survival rate was 78.4% and 62.6% in CRS-B and CRS-M group respectively with significant difference (χ=3.969, P=0.046), indicating better prognosis of CRS-B patients. The AUC for the lymph nodes ratio and N staging was 0.725 and 0.639 respectively. Multivariate analysis showed the pathological T staging was an independent risk factor of prognosis (HR=1.192, 95%CI:1.032-1.376, P=0.017).

CONCLUSIONSMen have more CRS than women. The interval time to canceration is correlated to the first operative procedure for CRS-B patients, while it is correlated to the age at the first operation for CRS-M patients. The major location of CRS is in the gastrointestinal anastomosis for CRS-B patients and in non-anastomosis area for CRS-M patients. Main postoperative complications include respiratory and infectious complications. Pathological T staging is an independent prognostic risk factor for CRS patients.
