OBJECTIVETo study the relationship between body mass index (BMI), hypertension and all-cause mortality in the elderly population in Beijing.

METHODSIn 1992, a cohort of 3 257 people above 55 years old was selected from 3 different areas of Beijing, i.e. urban and suburbs (both plain and mountain areas). Information on physical condition, history of chronic diseases, self-perceived health, as well as smoking and drinking status was collected. Blood pressure, body height and weight were measured among 2 086 of 3 257 subjects.

RESULTSBMI was decreasing with age, while the prevalence of hypertension increased with age. Meanwhile the prevalence of hypertension increased with age as well as with BMI. There was a reverse relationship between BMI and all-cause mortality, i.e. the risk of death was 39.0% lower for those with BMI = 20.0 - 24.9 kg/m(2) (Hazard ratio: 0.61, 95% Confidence interval: 0.49 - 0.75) and 62% lower for those with BMI >/= 25.0 kg/m(2) (Hazard ratio: 0.38%, 95% Confidence interval: 0.29 - 0.49) than those with BMI < 20.0 kg/m(2). After controlling for age, gender, residential place, hypertension as well as self-perceive health status and cognition function, low BMI remained a significant and independent predictor to death.

CONCLUSIONThe distribution of BMI was different in elderly from the youth. The findings suggested that it was important to control the body weight among the elderly hypertensives.

Objective:To explore the effect of digital technology and 3D printing technology combined with non-vascularized ilium bone in repairing post-traumatic bone defect in maxillary anterior area.Methods:A retrospective case series study was performed to analyze clinical data of 8 patients with severe bone defect in maxillary anterior area after trauma admitted to First Affiliated Hospital of Zhengzhou University from June 2013 to January 2018. There were 6 males and 2 females, with the age of 18-43 years [(31.9±9.0)years]. The maxillary bone was reconstructed before surgery by employing digital technology. The intercept range of ilium was determined according to the best form of defect to be recovered. Then the model and guide plate was printed out by employing 3D print technology. The titanium mesh was prebended on the model. The bone was extracted and Onlay bone grafting was performed according to the guide plate. The implant restoration was performed 6 to 9 months after operation, and porcelain crown restoration was performed 4 to 6 months later. The iliac bone survival and postoperative complications were detected 6 months after bone grafting. The near-middle-far and vertical bone elevation of the alveolar ridge as well as bone elevation of lip palatal were measured before implantation. The condition around the implants was observed 6 months after porcelain crown restoration. The visual analogue score (VAS) was used to evaluate the pain after iliac bone transplantation and implantation. The implant stability coefficient (ISQ) was applied to assess the stability of the implants on the day and 4 months after operation.Results:All the patients were followed up for 24-48 months [(33.3±9.7)months]. Eight patients with non-vascularized iliums were all survived. There was one patient with mild infection after bone grafting and one patient with gingival inflammatory hyperplasia after implantation, both of whom were healed after treatment. There was no obvious peri-implant inflammation or absorption of the grafted bone. The increase in height of the alveolar on the mesial and distal bone, vertical bone and labial-palatal bone was 30.28-39.67 mm, 9.58-11.32 mm and 2.06-7.41 mm, respectively. All the implants showed good osseointegration. The VAS after implantation was (3.4±0.7)points, significantly alleviated compared with the preoperational level [(7.3±2.0)points] ( P<0.05). The ISQ was 84.4±1.9 at postoperative 4 months, showing no significant difference from that on the day after operation (72.9±1.4) ( P>0.05). Conclusions:In repair of severe bone defect in maxillary anterior area after trauma, the digital and 3D printing technology combined with non-vascularized ilium can improve the survival rate of bone grafts. The implant restoration after operation can reduce pain, restore the patients' facial appearance and achieve satisfactory oral physiological function.

Objective: To evaluate an assay permitting amplification of target 5′-untranslated region (5′-UTR) sequences directly from clinical specimens and distinction among serotypes of enterovirus (EV). Methods: A total of 518 rectal swabs and 148 nasal swabs tested positive by pan-enterovirus real-time PCR were collected. 5′-UTR and the viral protein 1 (VP1) gene fragments were amplified and sequenced separately for serotyping. The inconsistent samples by 5′-UTR and VP1 serotyping were further determined by using the serotype-specific RT-PCR. Results: A total of 553 (83.0%) samples were detected by 5′-UTR serotyping and 318 (47.7%) were detected by VP1 serotyping in all 666 positive specimens, and there was significant difference in the detection rates between two methods in rectal and nasal swabs (P<0.001). For the rectal swabs, the mainly detected serotypes were CoxA6 (217), CoxA16 (88), EVA71 (40), CoxA10 (28) and CoxA4 (27) by 5′-UTR serotyping. Compared with the VP1 serotyping, the sensitivity and specificity of 5′-UTR serotyping were 57.1%-100% and 67.4%-98.1% respectively, with varied consistence with serotypes (kappa value 0.214-0.283). For the nasal swabs, the most frequently detected serotype was EVD68, with the sensitivity of 100%, the specificity of 91.1%, and the poor consistence (kappa value 0.217). CoxA6, CoxA16, EVA71, CoxA10 and EVD68 were further confirmed by serotype-specific RT-PCR. Using VP1 serotyping combined with serotype-specific RT-PCR as a reference method , the effect of performance of 5′-UTR serotyping on diagnosis was increased. Conclusions The performances of 5′-UTR serotyping in enterovirus vary with serotypes. The application of 5′-UTR serotyping should be considered comprehensively according to the purpose of the study.

Objective:To investigate the characteristics and relationship between the location of lower extremity deep vein thrombosis (DVT) and the site of pulmonary embolism in hospitalized patients.Methods:The data of patients with lower extremity DVT diagnosed by ultrasound examination and pulmonary embolism diagnosed by CT pulmonary angiography from December 2017 to December 2021 were analyzed retrospectively. According to the location of lower extremity DVT, the patients were divided into mixed DVT, proximal DVT, and distal DVT which was further divided into anterior/posterior tibial vein or peroneal vein thrombosis and calf muscular venous thrombosis. Mixed DVT was referred to the presence of both proximal and distal DVT. According to the involved site of pulmonary artery, pulmonary embolism was divided into three types: main pulmonary artery, left or right pulmonary artery trunk embolism, lobar pulmonary artery embolism and segmental pulmonary artery embolism. The location of lower extremity DVT, the site of pulmonary embolism, the clinical manifestation (shortness of breath, chest tightness, chest pain, hemoptysis, cough, lower limb swelling, lower limb pain, syncope, fever) and risk factors (fracture/trauma, tumor, diabetes, hypertension, atrial fibrillation, infection, surgery, autoimmune diseases, paralysis, pregnancy) of venous thromboembolism (VTE), and the level of D-dimer were analyzed.Results:A total of 209 patients were enrolled finally, including 127 patients with left lower extremity DVT (60.8%) and 82 with right lower extremity DVT (39.2%). Mixed DVT accounted for 39.2%, proximal DVT accounted for 17.3%, and distal DVT accounted for 43.5% (anterior/posterior tibial vein and peroneal vein thrombosis accounted for 14.8%, calf muscular venous thrombosis accounted for 28.7%). The incidences of main pulmonary artery embolism, left or right pulmonary artery trunk embolism in the mixed DVT and proximal DVT were significantly higher than those in the anterior/posterior tibial vein or peroneal vein thrombosis and calf muscular venous thrombosis [41.5% (34/82), 38.8% (14/36) vs. 16.2% (5/31), 10.0% (6/60)], with statistically significant differences (all P < 0.05). The incidences of pulmonary segmental artery embolism in the anterior/posterior tibial vein or peroneal vein thrombosis were higher than those in the mixed DVT and proximal DVT [41.9% (13/31) vs. 26.8% (22/82), 30.6% (11/36)], but the difference was not statistically significant (both P > 0.05). The incidences of pulmonary segmental artery embolism in the calf muscular venous thrombosis were significantly higher than those in the mixed DVT and the proximal DVT [66.7% (40/60) vs. 26.8% (22/82), 30.6% (11/36)], and the difference was statistically significant (both P < 0.05). The levels of D-dimer in patients with calf muscular venous thrombosis combined with main pulmonary artery embolism, left or right pulmonary artery trunk embolism were significantly higher than those in patients with calf muscular venous thrombosis combined pulmonary segmental artery embolism (mg/L: 6.08±3.12 vs. 3.66±2.66, P < 0.05). There were no significant differences in D-dimer levels in other patients with DVT combined with pulmonary embolism in different sites. In terms of the clinical manifestations of VTE, the incidences of lower limb swelling in the mixed DVT and proximal DVT were significantly higher than those in the anterior/posterior tibial vein or peroneal vein thrombosis and calf muscular venous thrombosis [54.9% (45/82), vs. 29.0% (9/31), 15.0% (9/60), both P < 0.05], the incidences of lower limb swelling in the proximal DVT were significantly higher than those in the calf muscular venous thrombosis [41.7% (15/63) vs. 15.0% (9/60), P < 0.05], there were no significant difference in the other clinical manifestations among the DVT groups. There was no significant difference in the incidence of VTE risk factors among the groups. Conclusions:The DVT of inpatients mostly occurred in the left lower limb, and the incidence of distal DVT was higher than that of proximal DVT. Mixed DVT and proximal DVT combined with pulmonary embolism mostly occurred in the main pulmonary artery, left or right pulmonary artery trunk, while distal DVT combined with pulmonary embolism mostly occurred in the pulmonary segmental artery. The levels of D-dimer in patients with lower extremity DVT combined with main pulmonary artery or left and right pulmonary artery trunk embolism were higher than those in patients with pulmonary lobe and segmental artery embolism. The incidence of lower extremity swelling in patients with mixed DVT and proximal DVT was higher than that in patients with distal DVT.

Methods: A total of 406 dengue fever patients admitted to Zhujiang hospital during 2015 to 2018 were analyzed for the clinical manifestations and laboratory examination results, retrospectively. ZIKV, CHIKV and the serotypes of DENV were detected in some samples. Results: DENV serotypes were tested in 96 dengue fever patients and 69 cases were positive. Among them, 58 cases (84.1%) were DENV-1, 10 cases (14.5%) were DENV-2, 1 case (1.5%) was DENV-3, DENV-4 was negative and no co-infection with different serotypes of dengue virus was found. Of all the 406 patients, 371 (91.4%) were diagnosed as dengue fever and 35 (8.6%) were severe cases. The most common manifestations included fever, weakness and rash. Significantly higher incidence (P<0.05) of bleeding, coughing, expectoration, vomiting and abdominal pain were found in severe dengue fever. The most common laboratory findings were leucopenia and thrombocytopenia. Significant increase(P<0.05) of total bilirubin, aspartate aminotransferase, serum creatinine, high-sensitivity C-reactive protein and procalcitonin were observed. ZIKV and CHIKV nucleic acids were tested in 380 dengue fever patients and the result were negative for both. Conclusions The incidence of dengue fever in Guangzhou increased in 2017 and 2018.Most cases of dengue fever were mild and DENV-1 was the dominant serotype.

OBJECTIVE： To establish the fingerprint of Mahai zhitan capsule， to determine the contents of main components， and to provide scientific basis for the stability and quality control of the preparation technology. METHODS： The determination was performed on Inertsil ODS-3 column with acetonitrile-0.1％ phosphoric acid as mobile phase （gradient elution） at the flow rate of 1.0 mL/min. The detection wavelength was set at 250 nm （0-23 min and 31-120 min） and 230 nm （23-31 min）. The column temperature was set at 30 ℃. HPLC fingerprint for 10 batches of Mahai zhitan capsule was established by using “similarity evaluation software for chromatographic fingerprint of traditional chinese medicine” （2012 edition） and the similarity was evaluated. The chromatographic peaks were assigned and identified with reference substance， negative samples without ingredient and substance control respectively， and the identified main components were quantitatively analyzed. RESULTS： The similarity of 10 batches of sample was more than 0.99； 20 common peaks were found， and 10 common peaks were identified. Among them， No. 1，13，14，15，16，17，18，19，20 chromatographic peaks originated from Rheum palmatum； No. 3，4，6，7 chromatographic peaks originated from processed Strychnos nuxvomica； No. 8 chromatographic peaks originated from Angelica sinensis； the corresponding source of medicinal materials was not found in No. 2，5，9，10，11，12 chromatographic peaks. By comparing the reference substances， No. 1，4，6，7，8，16，17，18，19 and 20 chromatographic peaks were identified as gallic acid， loganin acid， strychnine， brucine， ferulic acid， aloe-emodin， rhein， emodin， chrysophanol and emodin methyl ether， respectively. In the determination of identified five main components （loganin， strychnine， brucine， emodin and chrysophanol）， the methodological investigation met the relevant standards.

CONCLUSIONS： The established method is reliable， accurate， stable and simple， which could provide reference for the preparation technology and quality control of Mahai zhitan capsule.

OBJECTIVES: To explore the factors that influence self-management behavior in cancer patients based on the theoretical domain framework. METHODS: Studies in Chinese and English about factors influencing self-management behavior in cancer patients were searched from Wanfang database, CNKI, VIP, SinoMed, PubMed, Embase, CINAHL, Web of Science Core Collection, Cochrane library and Medline from inception to June 2022. Two investigators independently identified, extracted data, and collected characteristics and methodology of the studies. Factors were analyzed with Nvivo12, and the theoretical domain framework was mapped to the theoretical domain. Then the secondary node was generalized by theme analysis. Finally, the specific influencing factors were summarized and analyzed. RESULTS: Thirty-four studies were included for analysis. A total of 194 factors were mapped to 13 theoretical domains, and 31 secondary nodes were summarized. Theoretical domains environmental context and resources, social/professional role and identity, and beliefs about consequences were the most common factors. Knowledge, age, self-efficacy, disease stage, social support, gender, economic status and physical status were the most influential factors for self-management in cancer patients. CONCLUSIONS The influencing factors of self-management of cancer patients involve most of the theoretical domains, are intersectional, multi-source and complex.
