OBJECTIVEChinese herbal medicine has been extensively used in the treatment of vascular dementia (VaD), but lacked systematic review on its efficacy and safety. So we conducted a systematic review to assess the efficacy and safety of Chinese herbal medicine in treating VaD.
METHODSCNKI, CBM, PubMed, and Wiley Online Library were retrieved for randomized trials (RCTs) on Chinese herbal medicine treating VaD patients. Randomized parallel control trials by taking Chinese herbal medicine as one treatment method and placebos/cholinesterase inhibitors/Memantine hydrochloride as the control were included. Quality rating and data extraction were performed. RevMan5.2.0 Software was used for meta-analysis. Standardized mean difference (SMD) at 95% confidence interval (CI) was used to indicate effect indicators of results.
RESULTSSeven RCTs met the inclusive criteria. Totally 677 VaD patients were randomly assigned to the treatment group and the control group. Descriptive analyses were performed in inclusive trials. The cognitive function was assessed in all trials. Results showed Mini-Mental state examination (MMSE) score was better in the Chinese herbal medicine group than in the placebo group, but with no significant difference when compared with the donepezil group (P > 0.05). Adverse reactions were mainly manifested as gastrointestinal symptoms such as abdominal pain in the Chinese herbal medicine group. But they occurred more in the donepezil group than in the Chinese herbal medicine group.
CONCLUSIONSThe methodological quality of included trials was poor with less samples. Results of different trials were lack of consistency. Present evidence is not sufficient to prove or disapprove the role of Chinese herbal medicine in improving clinical symptoms and outcome indicators of VaD patients. Their clinical efficacy and safety need to be supported by more higher quality RCTs.

Chinese medical syndrome efficacy, as a second efficacy indicator, has been widely used in clinical trials of treating dementia by Chinese herbal medicine. The syndrome assessment tool is a key point in assessing the efficacy of Chinese medical syndrome. The syndrome assessment tool for dementia used nowadays needs to be optimized in content, reliability, and validity. In this paper, the authors reviewed some problems correlated with the design of Chinese medical assessment questionnaire on the basis of Chinese medical theories by combining the common requirements for questionnaire development.

The molecular characterization and phylogenetic analysis of hemagglutinin (HA) genes of human influenza H3N2 viruses in Guangdong, China from 2007 to 2010 were studied in this study. By space-time sampling of strains, the HA genes of H3N2 strains from Guangdong were sequenced and searched from Internet, and then the variation and evolution of HA genes were conducted by Lasergene 7.1 and Mega 5.05 and evolutionary rates were analyzed by epidemiological data. The phylogenetic tree was established by alignment of 17 Guangdong strains and 26 global reference strains. Ks rates and Ka rates of HA genes were 2.06 x 10(-3)-2.23 x 10(-3) Nt/Year and 1.05 x 10(-3)-1.21 x 10(3) Nt/Year during 2007-2010, while the velocity of HA1 evolution of Ka was 3. 13 times than that of HA2 evolution. Compared with HA of vaccine strain A/Perth/16/2009, the genetic homologies of Guangdong strains in 2009 reached to 98.8%-99.7% and of Guangdong strains in 2010 reached to 98.0%-98.4%. There were some amino acid substitutions in five epitope regions of HA1 during 2007-2010, especially in B region (N160K) and D region (K174R/N); the K189E/N/Q and T228A in RBS (receptor-binding site) occurred in 2010 as two glycoproteins sites substituted impacted on the HA1 antigenicity. The antigenicity of epidemic H3N2 strains in 2010 was to some degree different that of the vaccine strain A/ Perth/16/2009. According to that there were variations of B and D epitopes and two sites of RBS and two glycoprotein in Guangdong H3N2 HA1 genes, WHO/ CDC should recommend new representative strains during 2011-2012 influenza seasons if H3N2 HA genes further evolve in the near future.

BACKGROUNDThere are few studies on the arterial compliance of noise exposure. The purpose of this study was to understand the relationship between hearing loss, blood pressure and arterial compliance of female workers who exposed to occupational noise in a textile mill.
METHODSThe noise levels in the workplace were measured with a HS6288 sound level meter. Cumulated noise exposure (CNE) was calculated according to the noise intensity and the exposure period. Hearing ability and arterial compliance were measured in 618 noise exposed workers. The database was set up with EpiData and the statistical analysis was performed with SAS software 9.1.3.
RESULTSThe noise levels were 80.1dB (A) to 113.5dB (A), of which the levels at 92.5% of the noise monitoring sites were over the national standard. The incidence of high frequency hearing loss (HFHL) was 24.43% and language frequency hearing impairment (LFHI) was 0.81%. The incidence of hypertension was 7.93%. Both systolic blood pressure (SBP) and diastolic blood pressure (DBP) in the high frequency hearing loss group were significantly higher than those in the normal hearing group (P < 0.05), while C(1) (large artery compliance) and C(2) (small artery compliance) were significantly lower (P < 0.05). The high frequency hearing threshold (HFHT) of the hypertension group was significantly higher than in the normal blood pressure group (P < 0.05), while C(1) and C(2) were significantly lower (P < 0.05). C(1) and C(2) had a negative correlation with HFHT, SBP, DBP, mean of arterial pressure (MAP), pulse pressure (PP) and pulse rate (PR) (P < 0.05). The multiple regression analyses showed that blood pressure and PR were the main influencing factors on C(1) and C(2). LFHT was an influence on C(2) and HFHT on C(1).
CONCLUSIONSTextile mill noise pollution is very serious and has an obvious influence on worker's auditory function. The female workers with low artery compliance or with high blood pressure might be suffering from hearing loss; those with noise induced hearing loss might be suffering from hypertension if she is constantly exposed to loud industrial noise.

OBJECTIVETo evaluate the follow-up efficacy and safety on slow transit constipation (STC) treated with individualized deep puncture at Tianshu (ST 25).
METHODSOne hundred and twenty-eight cases of STC were randomized into a deep puncture group (64 cases), a western medication group (31 cases) and a shallow puncture group (33 cases) at the ratio of 2:1:1. In the deep puncture group, electroacupuncture of deep puncture was applied to bilateral Tianshu (ST 25). The needle was inserted perpendicularly and slowly at the acupoint and went deeply till penetrating the peritoneum, about 20 to 65 mm in depth. In the western medication group, lactulose oral liquid was prescribed for oral administration. In the shallow puncture group, electroacupuncture of shallow puncture was done at bilateral Tianshu (ST 25). The needle was inserted perpendicularly and slowly, 5 to 8 mm in depth. The treatment lasted 4 weeks in the three groups and the follow-up visit of 12 weeks and 6 month after treatment was performed respectively. The weekly defecation frequency, patient's satisfaction and safety of deep puncture at Tianshu (ST 25) were assessed before and after treatment in each group.
RESULTSIn the deep puncture group, the weekly defecation frequency was (1.79 +/- 1.05) times/week before treatment and was (3.90 +/- 1.43) times/week after 4-week treatment. It was (3.49 +/- 1.46) times/week in 12-week follow-up visit after treatment and was (3.51 +/- 1.42) times/week in 6-month follow-up visit after treatment. In the deep puncture group, the improvements in weekly defecation frequency, patient's satisfaction and short-term efficacy were same as those in the western medication group and the shallow puncture group (all P > 0.05). The long-term efficacy in follow-up visit was better remarkably than that in the western medication group (P < 0.05, P < 0.01). Besides, the combined medication was reduced and no adverse reaction occurred.
CONCLUSIONThe individualized deep puncture at Tianshu (ST 25) is effective in the treatment of STC and achieves the satisfactory long-term efficacy. This therapy displays the good effective advantage and deserves to be promoted in clinical practice of acupuncture and moxibustion therapeutic program as compared with the first-tier line of medication, lactulose oral liquid, recommended at home and abroad, in terms of the evidence-based medicine.

In order to solve the problem of long-term (>9 months) efficacy in the treatment of Alzheimer's disease (AD) by conventional therapy (CT), a staged and multiply-targeted sequential therapy based on the evolvement of patterns (STEP) was developed. Its main innovations include: (1) the time order of evolution of patterns defined by Chinese medicine (CM) in AD was found, that is, "the orderly pattern evolution starting from Shen (Kidney) deficiency, progressing to phlegm, stasis and fire, and worsening to severe toxin as well as functional collapse"; (2) the cascade hypothesis of Shen deficiency in AD and its sequential therapy based on Shen-reinforcing was proposed, that is, "reinforcing Shen in the early stage and throughout the whole process, resolving phlegm, activating blood and purging fire in the middle stage, detoxifying and replenishing vitality to stop the collapse in the advanced stage", and through meta-analysis, clinical drug use was optimized, thus the leap from "inferential selection" to "evidence-based selection" was realized; (3) the STEP regimen combined with CT maintained cognitive and behavioral stability in AD patients for at least 12 months, with cognitive enhancement and behavioral synergy after 9 months, and cognitive benefit was superior to CT at 9, 12, 15, 18, 21, and 24 months, respectively. The 2-year cognitive improvement rate was increased by 25.64% (P=0.020) and the cognitive deterioration rate was decreased by 48.71% (P=0.000). Among them, the cognitive and functional benefits of Shen-reinforcing therapy for very early AD (350 cases) for 1 year were better than the placebo (P<0.001), and the dementia conversion rate was reduced by 8.85% (P=0.002). The behavioral symptomatic relief of patients with vascular dementia received fire-purging therapy (540 cases) was superior to those received CT (P=0.016). These data suggested that the STEP regimen has synergistic effects on CTs at least in terms of cognitive benefit, and the earlier the use, the greater the benefit will have. Therefore, the STEP regimen should be considered as one of the clinical options, particularly for the dearth of effective pharmaceutical or immunological interventions that are currently available for AD.

OBJECTIVETo investigate the effect of GAPT, an extract mixture from Radix Ginseng, Rhizoma Acor tatarinowii, Radix Polygalae and Radix Curcuma (containing ingredient of turmeric), etc. on expression of tau protein and its phosphorylation related enzyme in hippocampal neurons of APPV717I transgenic mice.
METHODSSixty three-month-old APPV717I transgenic mice were randomly divided into model group, donepezil group [0.92 mg/(kg•d)], the low, medium and high dosage of GAPT groups [0.075, 0.15, 0.30 g/(kg•d), 12 in each group], and 12 three-month-old C57BL/6J mice were set as a normal control group, treatments were administered orally once a day respectively, and both the normal group and model group were given 0.5% sodium carboxymethyl cellulose solution. Immunohistochemistry (IHC) and Western blot analysis were used to detect the expression of total tau protein (Tau-5), cyclin-dependent kinase 5 (CDK5) and protein phosphatase 2A (PP2A) in hippocampal neurons of experimental mice after 8-month drug administration (11 months old).
RESULTSIn the model group, the expression of Tau-5 and CDK5 were increased, whereas the expression of PP2A was decreased in hippocampal neurons, which were signifificantly different compared with that in the normal group (all P<0.01). IHC test indicated the number and area of either Tau-5 or CDK5 positive cells were decreased with a dose-depended way in GAPT groups, and an increase of PP2A. Compared with the model group, the changes were signifificant in GAPT groups (P<0.05 or P<0.01). Similar results were shown by Western blot.
CONCLUSIONGAPT could attenuate abnormal hyperphosphorylation of tau protein in hippocampal neurons of APPV717I transgenic mice via inhibiting the expression of CDK5 and activating the expression of PP2A.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.
METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.
RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).
CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

BACKGROUNDPatients on hemodialysis have a high-mortality risk. This study analyzed factors associated with death in patients on maintenance hemodialysis (MHD). While some studies used baseline data of MHD patients, this study used the most recent data obtained from patients just prior to either a primary endpoint or the end of the study period to find the characteristics of patients preceding death.
METHODSParticipants were selected from 16 blood purification centers in China from January 2012 to December 2014. Patients' data were collected retrospectively. Based on survival status, the participants were divided into two groups: survival group and the death group. Logistic regression analysis was performed to determine factors associated with all-cause mortality.
RESULTSIn total, 4104 patients (57.58% male, median age 59 years) were included. Compared with the survival group, the death group had more men and more patients with diabetic nephropathy (DN) and hypertensive nephropathy. The patients preceding death also had lower levels of diastolic blood pressure, hemoglobin, serum albumin, serum calcium, serum phosphate, Kt/V, and higher age. Multivariate analysis revealed that male sex (odd ratio [OR]: 1.437, 95% confidence interval [CI]: 1.094-1.886), age (OR: 1.046, 95% CI: 1.036-1.057), and presence of DN (OR: 1.837, 95% CI: 1.322-2.552) were the risk factors associated with mortality. High serum calcium (OR: 0.585, 95% CI: 0.346-0.989), hemoglobin (OR: 0.974, 95% CI: 0.967-0.981), albumin (OR: 0.939, 95% CI: 0.915-0.963) levels, and dialysis with noncuffed catheter (OR: 0.165, 95% CI: 0.070-0.386) were protective factors based on a multivariate analysis.
CONCLUSIONSHemodialysis patients preceding death had lower hemoglobin, albumin, and serum calcium levels. Multivariate analysis showed that male sex, age, DN, low hemoglobin, low albumin, and low serum calcium were associated with death in hemodialysis patients.

OBJECTIVE:
To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction.
METHODS:
Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period.
RESULTS:
After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year.
CONCLUSION
Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).
