Objective:To explore the medication regularity and prescription rule of Chinese herbal medicine in the treatment of cardiac failure.Methods:The China Patent Publication Notice of the State Intellectual Property Office (http://epub.sipo.gov.cn/) was rearched and retrievedfor Chinese herbal medicine for the treatment of heart failure. The Traditional Chinese Medicine (TCM) inheritance support system (V 2.5) was used to input the prescription information and establish the database. The association rules, mutual information method, entropy clustering of complex systems and other data mining methods were used for commonly used drugs, combination rule and new prescription of core group.Results:A total of 101 prescriptions were included, involving 316 drugs. The frequency of commonly used drugs were Astragali Radix (59.41%), Poria (41.58%), Salviae Miltiorrhizae Radix et Rhizoma (40.59%), Descurainiae Semen Lepidii Semen (34.65%), Aconiti Lateralis Radix Praeparata (33.66%), and the medicinal properties were mainly warm, and the sweet taste. The main flavors weresweet, bitterness, and pungency, and the main sources of meridians belonged to liver, spleen, heart, lungs and kidneys. The most commonly used drug combinations contribute to supplement Qi, invigorate blood circulation and stasis, warm Yang, remove moisture. There were 12 core drug groups and 6 new prescriptions for heart failure. Conclusions:Analysis on formulas for heart failure shows that the prescriptions focus on supplementing qi and activating blood circulation, warming Yang reducing dampness, invigorating spleen, and nourishing Yin, dispel turbid, solid Yang. It can provide reference for clinical treatment to improve curative effect and standardize prescription medication.

Objective:To examine the association of blood uric acid (UA) and cognitive impairment (CI) among oldest-old adults in China.Methods:Data was collected in 9 longevity areas of China from Healthy Aging and Biomarkers Cohort Study (HABCS) conducted during 2017-2018. Finally,1, 622 elderly aged 80 years and older with complete information on blood UA and cognitive function score were included in this study. Information on demographic characteristics, lifestyle, and health status were collected through questionnaire and physical examination. Venous blood samples of the participants were collected to test blood UA level. Cognitive impairment (CI) was assessed using the Chinese Mini-Mental State Examination (MMSE) according to personal educational level. Generalized Estimating Equations (GEE) model for binary data was used to analyze the association of blood UA and CI, and further compared the associations among different age and body mass index (BMI) groups.Results:Of the 1 622 oldest-old, the mean age was (92.2±8.1) years, 656 (40.4%) were male, the mean level of blood UA was (343.3±86.2) μmol/L, and 482 (29.7%) oldest-old had CI. Compared with the lowest quartile of UA, the risks of CI in the second, third and highest quartiles were gradually reduced, the corresponding ORs and 95% CI were 0.99 (0.71-1.33), 0.87 (0.68-0.94) and 0.69 (0.48-0.85), respectively; and the linear trend test was statistically significant ( P<0.001). Subgroup analysis showed that the effects of higher UA associated with lower risk of CI were stronger in younger oldest-old (aged 80-89 years) and thinner group (BMI<24) ( Pinteraction<0.05). Conclusions:Blood UA was negatively associated with the risk of having CI in the oldest-old among the nine longevity areas of China.

Objective:To investigate the relationship between the neutrophil-to-lymphocyte ratio (NLR) and the risk of depression symptoms among older adults aged 65 and above in 9 longevity areas of China.Methods:Data was collected in 9 longevity areas of China from Healthy Aging and Biomarkers Cohort Study (HABCS) conducted between 2017 and 2018. Finally,2018 elderly aged 65 years and above with complete information on neutrophil count, lymphocyte count and depressive symptoms were included in this study. Information on demographic characteristics, lifestyle, and health status was collected through questionnaire and physical examination. Complete blood counts which included lymphocytes and neutrophils were obtained by testing venous blood samples. Participants were divided into four groups by the quartile of NLR level, i.e. Q1, Q2, Q3, Q4. Logistic regression model was applied to analyze the association of NLR with depression symptoms. Results:Among 2 018 older adults, the mean(±SD) age was 82.6(±10.73), 1 032(51.14%) were male, 390(19.33%) were detected with depressive symptoms. Compared with participants of NLR in the 1 st quartile, the OR(95% CI) of risk for depressive symptoms was 1.47 (0.99, 2.19), 1.67 (1.13, 2.47) and 1.95 (1.32, 2.89), respectively. Conclusion:Increased NLR level is significantly related to depressive symptoms among elderly aged 65 years and above in 9 longevity areas in China.

Objective:To investigate the association of blood arsenic level with hyperuricemia among elderly aged 65 years and older.Methods:Data was collected in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study between 2017 and 2018. 2 438 participants aged 65 years and older with complete information on blood arsenic and uric acid were included in this study. Information including demographics characteristic, life style and health status was collected by questionnaire and physical examination. Meanwhile, venous blood was collected to detect the levels of blood arsenic and uric acid. Subjects were stratified into three groups (low, middle and high) by tertiles of blood arsenic level.

Objective To investigate the effect of taurine transporter in the process of protection of brain edema in rats with severe traumatic head injury. Methods A total of 24 Male Sprague-Dawley rats were randomly divided into 4 groups. Except the control rats (Group Sham), all other three groups were subjected to lateral fluid percussion head injury. The TBI (Traumatic brain injury) models (Group TBI) and surgical control rats (Group Sham) were injected with saline through caudal vein after surgery, while the Taurine prevention and Taurine treatment models (Group Pre Tau and Group Tau) were injected with 120 g/L taurine solution before or after surgeries respectively. Water content in each brain, mRNA and protein expres?sion of aquaporin 4 and taurine transporter in the injured rat brain hemispheres were all evaluated over the time course of the study (7 d) in each group. Results Compared with rats in Group Sham, water content in each brain increase, mRNA tran?scription and protein expression of AQP4 were both up regulated but the mRNA transcription and protein expression of TauT were both down-regulated in rats in TBI group. Compared with rats in TBI group, brain water content, mRNA transcription and protein expression of AQP4 all decrease while mRNA transcription and protein expression of TauT all increase in rats in Pre tau and Tau groups. There is no statistical difference of TauT expression between rats in pre-tau group and Tau group. Conclusion Taurine exert its neuron protection role through draining water content from brain and down regulating expres?sion of AQP4 but rising expression of TauT after TBI.

Objective To analyze the clinical effects of individualized comprehensive physiotherapy interventions for temporomandibular disorders (TMD).Methods Data of 307 patients with TMD treated between April 2011 and March 2012 in the authors' department were collected and reviewed.All the patients were treated with individualized comprehensive physiotherapy approach based on the patient's category in research diagnostic criteria for TMD (RDC/TMD),such as patient education,ultrashort-wave diathermy,ultrasound therapy,soft tissue massage,joint mobilization and stabilization exercise.The treatment was administered for 3 weeks.The baseline and endpoint outcome assessment measures were maximum active mouth opening (mm),visual analogue scale (VAS) score and joint clicking (100％ before treatment).Results At the end of treatment,the patient's maximum active mouth opening [(36.95 ± 6.59) mm],VAS score (1.21 ± 0.62) and joint clicking [(29 ± 17) ％] improved significantly (P ＜ 0.05) compared to baseline.Conclusions Individualized comprehensive physiotherapy interventions can improve symptoms of TMD,such as joint clicking,pain,limited mouth opening.

AIM: To investigate the effect of berberine (Ber) on the activation and proliferation of T lymphocytes and its mechanism of action. METHODS: Whole peripheral blood from normal subjects was stimulated with phytohemagglutinin (PHA) or phorbol ester (PDB) plus ionomycin (Ion) and the expression levels of CD69 and CD25 were evaluated with flow cytometry after the staining with appropriate fluorescent monoclonal antibody. The distribution of cell cycles was analyzed by propidium iodide staining and dead cells by 7-aminoactinomycin live staining. RESULTS: 100 ?mol/L and 50 ?mol/L of Ber had significant inhibition of the expression of CD69 on T cells stimulated with PDB plus Ion or PHA, while effect of 25 ?mol/L Ber was not significant. And as time of action extended, the extent of inhibition decreased. For the expression of CD25, Ber at the concentrations as above all exerted significant inhibitory effect in a dose-dependent manner. Moreover, Ber could block lymphocytes cell cycle progression from G_0/G_1 phase to S and G_2/M phase without phase specificity. Besides, live staining analysis revealed that Ber did not have significant cytotoxicity on lymphocytes. CONCLUSIONS: Ber significantly inhibits the expression of early and mid activation antigens of T cells and also blocks the progression of lymphocytes cell cycles. These results suggest that Ber exerts immunosuppression effect through inhibiting the activation and proliferation of T cells.
