		                        			ObjectiveTo observe the possible mechanism of Dihuang Yinzi Decoction (地黄饮子) for improving cognitive dysfunction in Alzheimer's disease (AD) from the perspective of retina. MethodsForty-five APP/PS1 mice (AD model mice) were randomly divided into model group, Dihuang Yinzi Decoction group, and memantine group, with 15 mice in each group, while 15 wild-type C57BL/6J mice from the same litter were used as blank group. Mice in Dihuang Yinzi Decoction group were given Dihuang Yinzi Decoction 30.03 g/(kg·d) by gavage, mice in the memantine group were given memantine hydrochloride 6.1 mg/(kg·d) by gavage, and mice in the blank group and the model group were given normal saline 2 ml/(kg·d) by gavage for 4 consecutive weeks. Fasting blood glucose was measured weekly. After 4 weeks of intervention, oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were performed; Morris water maze was used to detect the changes in spatial memory ability of mice; glucose oxidase method was used to detect retinal glucose content of mice; enzyme-linked immunosorbent assay (ELISA) was used to detect serum and retinal insulin content of mice, and Homeostatic Model Assessment of insulin resistance (HOMA-IR) was calculated. Hematoxylin-eosin (HE) staining was performed to observe the histopathological changes in the retina, and the retinal thickness and ganglion cell number were counted; protein immunoblotting was performed to detect the retinal pathway-associated proteins [insulin receptor substrate 1 (IRS1), phosphorylated insulin receptor substrate 1 (pIRS1), phosphatidylinositol-3-hydroxykinase (PI3K), protein kinase B (Akt1), phosphorylated protein kinase B (pAkt1)] expression; retinal glucose transporter protein 4 (GLUT4) expression was detected by immunohistochemistry. ResultsCompared with the blank group, fasting blood glucose of mice in the model group at weeks 1, 2, 3, and 4, blood glucose and area under the curve (AUC) at different time point of OGTT and ITT test, fasting serum insulin, and HOMA-IR increased (P<0.05, P<0.01); in the Morris water maze experiment, the escape latency increased from day 3 to day 5, and the number of crossing platforms, the percentage of target quadrant distance, and the percentage of target quadrant time decreased (P<0.05, P<0.01); the outer nuclear layer of the retina became sparse, thinner, and the number of ganglion cells decreases (P<0.01); the expression level of retinal glucose increased, while the expression levels of insulin, pIRS1/IRS1, PI3K/β-Actin, pAkt1/Akt1, and GLUT4 proteins decreased (P<0.01). Compared with the model group, fasting blood glucose at week 4, blood glucose at each time point of the OGTT and ITT tests AUC decreased (P<0.05, P<0.01), and fasting serum insulin and HOMA-IR decreased (P<0.05) in Dihuang Yinzi Decoction group; In the Morris water maze test, the escape latency shortened on day 4 and day 5, number of platform crossings, target quadrant distance as a proportion of total distance, and target quadrant movement time as a proportion of total time decreased (P<0.05, P<0.01); retinal pathological changes alleviated, and retinal thickness and ganglion cell number increased (P<0.01); retinal glucose content decreased, and retinal pIRS1/IRS1, PI3K/β-Actin, and GLUT4 protein expression elevated (P<0.05 or P<0.01). ConclusionsDihuang Yinzi Decoction can improve cognitive dysfunction of Alzheimer's disease, which may be related to regulating retinal insulin content and insulin signaling pathway.

		                        			Objective: To assess the prevalence, risk factors and treatment of anemia in patients with chronic kidney disease (CKD). Methods: A descriptive method was used to analyze the prevalence and treatment of anemia in CKD patients based on regional health data in Yinzhou District of Ningbo during 2012-2018. The multivariate logistic regression analysis was used to identify independent influence factors of anemia in the CKD patients. Results: In 52 619 CKD patients, 15 639 suffered from by anemia (29.72%), in whom 5 461 were men (26.41%) and 10 178 were women (31.87%), and anemia prevalence was higher in women than in men, the difference was significant (P<0.001). The prevalence of anemia increased with stage of CKD (24.77% in stage 1 vs. 69.42% in stage 5, trend χ2 test P<0.001). Multivariate logistic regression analysis revealed that being women (aOR=1.57, 95%CI: 1.50-1.63), CKD stage (stage 2: aOR=1.10, 95%CI: 1.04-1.16;stage 3: aOR=2.28,95%CI: 2.12-2.44;stage 4: aOR=4.49,95%CI :3.79-5.32;stage 5: aOR=6.31,95%CI: 4.74-8.39), age (18-30 years old: aOR=2.40,95%CI: 2.24-2.57, 61-75 years old: aOR=1.35,95%CI:1.28-1.42, ≥76 years old: aOR=2.37,95%CI:2.20-2.55), BMI (<18.5 kg/m2:aOR=1.29,95%CI: 1.18-1.41;23.0-24.9 kg/m2:aOR=0.79,95%CI: 0.75-0.83;≥25.0 kg/m2:aOR=0.70,95%CI: 0.66-0.74), abdominal obesity (aOR=0.91, 95%CI: 0.86-0.96), chronic obstructive pulmonary disease (aOR=1.15, 95%CI: 1.09-1.22), cancer (aOR=3.03, 95%CI: 2.84-3.23), heart failure (aOR=1.44, 95%CI: 1.35-1.54) and myocardial infarction (aOR=1.54, 95%CI:1.16-2.04) were independent risk factors of anemia in CKD patients. Among stage 3-5 CKD patients with anemia, 12.03% received iron therapy, and 4.78% received treatment with erythropoiesis-stimulating agent (ESA) within 12 months after anemia was diagnosed. Conclusions: The prevalence of anemia in CKD patients was high in Yinzhou. However, the treatment rate of iron therapy and ESA were low. More attention should be paid to the anemia management and treatment in CKD patients.

		                        			This study aimed to explore the characteristic role of Puerariae Lobatae Radix(PLR) in Gegen Decoction for the treatment of primary dysmenorrhea(PD). Estrogen(E_2) was combined with oxytocin to establish a mouse model of PD. The mice were randomly divided into a normal group, a model group, a Gegen Decoction group, a PLR-free Gegen Decoction group, a PLR group, and a positive drug group(ibuprofen). Writhing response times and writhing incubation of mice in each group were tested by behavio-ral assessment, and the serum levels of prostaglandin F_(2α)(PGF_(2α)), prostaglandin E_2(PGE_2), E_2, and progesterone(PROG) were detected by ELISA kits. Western blot method was adopted to detect cyclooxygenase-2(COX-2) and estrogen receptor alpha(ER_α) expression levels in uterine tissues. Doppler ultrasound was employed to detect changes in uterine artery blood flow in mice, including peak systolic blood flow velocity(maximum velocity), end-diastolic velocity(minimum velocity), peak systolic blood flow velocity/end-diastolic velocity(S/D), pulsatility index(PI), and resistive index(RI). Histopathological changes in the uterus were detected by HE staining. Based on the oxytocin-induced isolated uterine contraction model, the effects of Gegen Decoction, PLR-free Gegen Decoction, and PLR on the amplitude, frequency, and activity of isolated uterine contraction were compared to investigate the role of PLR in Gegen Decoction for the treatment of PD. The results showed that compared with the Gegen Decoction group, the PLR-free Gegen Decoction improved the indicators of PD except for E_2 content, ER_α expression, and uterine artery blood flow. PLR could significantly down-regulate the serum content of E_2 and the protein expression of uterine ER_α, and improve the uterine artery blood flow. The data suggested that PLR, as the sovereign drug of Gegen Decoction, might function in Gegen Decoction for the treatment of PD by mediating E_(2 )and improving the uterine artery blood flow.

		                        			Zerumbone(ZER), one of humulane-type sesquiterpenoids, showed its unique advantage against tumor activities. The main underlying mechanisms include inhibiting the growth and proliferation of cancer cells, inducing apoptosis of cancer cells and differentiation of cancer cells, regulating immune function, inhibiting invasion and metastasis of cancer cells, and reversing multidrug resistance of cancer cells. Studies on ZER focusing its cytotoxic or anti-tumor is one of hot topic. Currently, with the increasing studies on ZER, the clarified mechanisms are getting rich. The present paper describes a summary of its anti-tumor mechanism of action and helps to provide significant reference to more in-depth research.

		                        			OBJECTIVE:
		                        			To investigate the clinical significance of tissue factor (TF) and vascular endothelial growth factor (VEGF) expression on peripheral blood CD14 positive monocytes in patients with diffuse large B cell lymphoma (DLBCL).
		                        		
		                        			METHODS:
		                        			The expressions of TF and VEGF on peripheral CD14 monocytes in 41 patients with DLBCL (DLBCL group) before chemotherapy and after 4 chemotherapeutic courses, and in 20 healthy subjects (control group) were detected by flow cytometry respectively, meanwhile, the relationship of the expression of TF and VEGF with international prognostic indexes (IPI) and short-term effects were analysed.
		                        		
		                        			RESULTS:
		                        			The expression levels of TF and VEGF on peripheral CD14 monocytes in DLBCL group were significantly higher than those in control group (P<0.01), and a positive correlation was found between the two groups (r=0.755, P<0.01). The expression of TF and VEGF on CD14 monocytes in patients with prognostic risk factors significantly increased as compared with those in patients without prognostic risk factors (P<0.05), but there were no significant differences of TF and VEGF expressions on CD14 monocytes in DLBCL group with different sex, age, subtypes (P>0.05). As compared with patients without prognostic risk factors, the expression levels of TF and VEGF on CD14 monocytes of patients with prognostic risk factors significantly increased (P<0.05). The expression of TF and VEGF on CD14 monocytes in DLBCL group showed an increasing tendency along with the increase of IPI index (P<0.01). The expression levels of TF and VEGF on CD14 monocytes in remission group before chemotherapy were lower than those in non-remission group (P<0.01); after chemotherapy, the expression levels of TF and VEGF on CD14 monocytes in remission group were lower than those before chemotherapy (P<0.05), while the TF and VEGF expression levels in non-remission group were no singnificauly different from TF and VEGF levels before chemtherapy (P>0.05), the survival of patients in group with low expression of TF and VEGF was superior to that in group with high expression of TF and VEGF (P<0.05).
		                        		
		                        			CONCLUSION
		                        			The paripheral blood CD14 monocytes in DLBCL patients highly express the TF and VEGF, which relate with IPI, therapeutic efficacy and survival, thus the TF and VEGF expression levels are of reference significance for evaluating the therapeutic efficacy and prognosis of patients.

		                        			OBJECTIVE:
		                        			To evaluate the clinical effect of acupuncture on smoking cessation and withdrawal symptoms and to explore the influence factors of acupuncture on smoking cessation.
		                        		
		                        			METHODS:
		                        			A total of 500 subjects with tobacco dependence were randomized into an acupuncture group, an auricular therapy group, an acupuncture plus auricular therapy group, a TENS group and a nicotine replacement therapy group (NRT group), 100 cases in each one. In the acupuncture group, acupuncture was applied at Baihui (GV 20), Lieque (LU 7), Hegu (LI 4) and Zusanli (ST 36). The treatment was given 5 times a week, once a day in the first 2 weeks. The treatment was given once every 2 days in the week 3 and 4, 3 times a week, and twice a week, once every 3 days in the week 5 to 8. In the auricular therapy group, the ear point pressure therapy was used at shenmen (TF), neifenmi (CO), pizhixia (AT) and jiaogan (AH), 3 times a week. In the acupuncture plus auricular therapy group, acupuncture and auricular therapy were adopted with the same points and manipulation as the previous two groups. Acupuncture was given 3 times a week and the auricular therapy was given twice a week. In the TENS group, SDZ-Ⅱ B type electric acupuncture apparatus was used to stimulate Lieque (LU 7) and Zusanli (ST 36), once a day. In the NRT group, the nicotine patch was used on the chest, back and the upper arms of the subjects, once a day. The duration of treatment was 8 weeks as one course in every group. Afterwards, the 16-week follow-up was conducted. The time-point withdrawal rate was evaluated by the level of urine cotinine in 8 weeks of treatment and in the follow-up in the subjects of 5 groups. The persistent withdrawal rate was evaluated by the self-report of the subjects in 8 weeks of treatment as well as in the follow-up in the 5 groups. The withdrawal effect, the score of the fagerstrom test for nicotine dependence (FTND) and the score of the heaviness of smoking index (HSI) were compared among the groups. Twenty indexes were selected as the potential influence factors, the 72 h withdrawal rate based on the level of urine cotinine in 8 weeks of treatment and in the follow-up was taken as the dependent variable. Using the two categories of Logistic regression analysis, the influence factors of therapeutic effect of acupuncture were screened for smoking cessation.
		                        		
		                        			RESULTS:
		                        			After 8 weeks of treatment, the time-point withdrawal rate in the subjects among the groups was NRT group > acupuncture plus auricular therapy group > auricular therapy group > acupuncture group > TENS group. In the follow-up, the time-point withdrawal rate was acupuncture plus auricular therapy group > NRT group > acupuncture group > TENS group > auricular therapy group, but without statistical significance in comparison (>0.05). After 8 weeks of treatment, the persistent withdrawal rate in the subjects among the groups was auricular therapy group > TENS group > acupuncture group > acupuncture plus auricular therapy group > NRT group. In the follow-up visit, the persistent withdrawal rate was auricular therapy group > TENS group > acupuncture plus auricular therapy group > acupuncture group > NRT group. The result in the auricular therapy group was better than all of the other 4 groups (<0.05). Except in the follow-up visit, FTND score in the acupuncture group was lower than the auricular therapy group (<0.05), FTND score and HSI score were not different significantly in statistics among the groups either in 8 weeks of treatment or in the follow-up (>0.05). The regression analysis showed that the factors, i.e. nationality, educational background, drinking frequency, pre-treatment FTND score, pre-treatment HSI score and smoking cessation for physical reason in family, were correlated significantly with the withdrawal result after 8-week treatment (<0.05). The factors, i.e. education background, smoking age, pre-treatment FTND score and different therapeutic methods, were correlated significantly with the withdrawal result in the follow-up (<0.05).
		                        		
		                        			CONCLUSION
		                        			Acupuncture combined with auricular therapy effectively reduce nicotine dependence and smoking intensity and relieve withdrawal symptoms. There are many factors that affect the withdrawal effect in smoking cessation. Hence, the influence factors in smoking cessation with acupuncture should be clearly determined so as to develop the individual regimen for smoking cessation and improve the clinical therapeutic effect of acupuncture on smoking cessation.
