Magnesium valproate adjuvant therapy on patients with dementia: A protocol for systematic review and meta-analysis.

BACKGROUND: With the aging population, the prevalence and incidence of dementia disease will continue to rise, and the associated economic burden is increasing as well. However, the available anti-dementia therapeutic arsenal is limited. Meanwhile, magnesium valproate (VPM) as an adjuvant therapy had a general positive effect on the cognitive function and psychiatric symptoms of patient with dementia (PwD). At present, there is lack of meta-analysis focusing on cognitive improvement and disease-modifying about VPM-assisted therapy in the present peer-reviewed literature. Thus, we aimed to likely analyze the efficacy and safety of VPM adjuvant therapy of PwD. METHODS: We will research MEDLINE via PubMed, Cochrane Library, EBSCO, Embase, China National Knowledge (CNKI) and Wan fang databases to gather relevant data on VPM assistant therapy on the PwD. Meta-analysis will be performed using Stata16.0 software. RESULTS: We aim to evaluate the efficacy and safety of VPM in the adjuvant treatment of PwD. CONCLUSION: VPM maybe plays an active role in the treatment of dementia patients and this research will provide reliable evidence for clinicians in therapy of PwD.

Long-Term Traditional Chinese Medicine Combined with NA Antiviral Therapy on Cirrhosis Incidence in Chronic Hepatitis B Patients in the Real-World Setting: A Retrospective Study.

OBJECTIVE: To evaluate the impact of long-term Traditional Chinese Medicine (TCM) syndrome differentiation combined with antiviral therapy with Nucleos (t) ide analogues (NAs) on the incidence of cirrhosis in patients with chronic hepatitis B. METHODS: This retrospective cohort study included 521 patients with chronic hepatitis B who underwent a treatment course of ≥3 years from 1998-2019. Of the 521 patients, 261 were defined as TCM users while 260 were TCM nonusers (control group). All the enrolled subjects were followed up until February 2019 to measure the incidence and hazard ratio (HR) of cirrhosis, and the Cox proportional hazards regression model was used to analyze the independent factors affecting the occurrence of cirrhosis. RESULTS: The cumulative incidence of TCM users and nonusers was 6.9% and 13.5%, respectively (P=0.013). Results of the Kaplan-Meier analysis demonstrated that TCM users had a significantly lower cumulative incidence of cirrhosis than TCM nonusers (P=0.011), and TCM users had a significantly lower liver cirrhosis risk than TCM nonusers (adjusted HR = 0.416, 95% CI, 0.231-0.749). The histological evaluation revealed improved fibrosis in 45.0% of TCM users and 11.1% of TCM nonusers (P=0.033). The analysation of the prescriptions including total 119 single Chinese herbs medicinal demonstrated that "replenish qi and fortify the spleen," "clear heat and dispel dampness," and "soothe the liver and regulate qi" are the main treatment methods of TCM for CHB. CONCLUSIONS: Our study demonstrated that long-term TCM use may attenuate liver cirrhosis risk in patients with chronic hepatitis B (CHB).

Baicalin Is Curative Against Rotavirus Damp Heat Diarrhea by Tuning Colonic Mucosal Barrier and Lung Immune Function.

BACKGROUND: Previous studies have indicated that rotavirus (RV) is a causative factor for diarrhea and gastroenteritis in pediatric and neonatal settings. Baicalin has many functions, including antibacterial, antiinflammatory, and antihypertensive activities. However, the immunological mechanism of RV-induced diarrhea with heat-dampness syndrome (RV-DH) remains unclear. AIMS: The aim of this study is to explore the role of baicalin in RV-DH diarrhea and its underlying mechanism. METHODS: A mouse model of pediatric RV-DH diarrhea was established and treated with baicalin. The concentrations of cytokines were detected by enzyme-linked immunosorbent assay. Messenger RNA (mRNA) expression levels were detected by quantitative real-time polymerase chain reaction (qRT-PCR), while protein expression levels were determined by Western blotting and immunohistochemistry. Flow cytometry was used to detect the frequency of lymphocytes. RESULTS: The concentrations of interleukin-1ß (IL-1ß), IL-2, IL-6, IL-8, RVvb, and secretory immunoglobulin A (SIgA) in bronchoalveolar lavage fluid (BALF) and colonic mucosa were significantly increased in the RV-DH group. Decreased expression of occludin, claudin-1, and zonula occludens-1 (ZO-1) indicated loss of tight junction function and disturbances in intestinal mucosal permeability in the RV-DH group. Flow cytometry analysis showed a high rate of CD8+ lymphocytes and low amount of CD4+ lymphocytes in the RV-DH group. Treatment of RV-DH mice with baicalin significantly reduced the duration of diarrhea and ameliorated the symptoms and pathological and immunological changes. Furthermore, baicalin inhibited STAT1 and activated STAT3 signaling pathways. CONCLUSIONS: These findings indicate the curative and immunoregulatory properties of baicalin and have direct practical and clinical relevance for the treatment of RV-DH enteritis in humans.

Intradermal thumbtack needle buried Neiguan (P6) point for prevention of postoperative nausea and vomiting in patients undergoing craniotomy: study protocol for a randomised controlled trial.

INTRODUCTION: Postoperative nausea and vomiting (PONV) is among the most common adverse reactions following anaesthesia and surgery. Recent clinical studies have reported that the average incidence is about 30%, while in patients specifically undergoing neurosurgery, the incidence can be as great as 73%. Studies also suggest that its occurrence increases the risk of intracranial haematoma and haemorrhage. The objective of this study is to evaluate the effectiveness of intradermal thumbtack needle buried Neiguan (pericardium 6 (P6)) point therapy in the prevention of PONV in patients undergoing craniotomy under general anaesthesia. METHODS AND ANALYSIS: This is a single-centre, three-arm, randomised controlled trial. 180 participants are randomly assigned to either an acupuncture, intradermal thumbtack needle or control group in a 1:1:1 ratio. The P6 of the acupuncture group is punctured at both sides perpendicularly to a depth of 20 mm. Needles are retained for 30 min and stimulated every 10 min to maintain the de qi. The therapy includes two treatments; the acupuncture is administered immediately after and 24 hours after surgery. For the intradermal thumbtack needle group, the intradermal thumbtack needle is quickly inserted into the skin and embedded at P6 acupoints bilaterally. Patients and their families are asked to press the needlepoint with the onset of nausea, vomiting, bloating, pain and other reported discomforts. The needle is replaced after 24 hours. The therapy is administered immediately after and 24 hours after surgery. For the control group, no intervention is carried out. The incidence of PONV within 48 hours after craniotomy across the three groups is observed. Other observations include: (1) assessment of nausea score (severity of nausea) and pain score (visual analogue scale) 0-2, 2-6, 6-24 and 24-48 hours after craniotomy under general anaesthesia; (2) assessment of total rescue antiemetic dosage 0-48 hours after craniotomy under general anaesthesia; (3) length of hospital stay and (4) patient satisfaction score with PONV management. We will perform all statistical analysis following the intention-to-treat principle. ETHICS AND DISSEMINATION: Ethics approval has been granted by the Bioethics Subcommittee of the West China Hospital, Sichuan University: the approval number is 2018 (number 231). Results will be expected to be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ChiCTR1800017173.

[Distribution of Syndrome Types of Chinese Medicine in Acute Infectious Diarrhea].

OBJECTIVE: To observe syndrome types of Chinese medicine (CM) and distribution features of acute infectious diarrhea patients. METHODS: A retrospective study was performed in 465 acute infectious diarrhea patients. The distribution of CM syndrome and syndrome types in different seasons and genders were analyzed. RESULTS: Lack of appetite [381 (81.94%)], fatigue [350 (75.27%)], abdominal pain [338 (72.69%)], tenesmus [325 (69.89%)], anal scorching hot [276 (59.35%)], nausea [25 (55.48%)], diarrhea [249 (53.55%)], short yellow-urine [240 (51.61%)], thirsty [210 (45.16%)], and abdominal distention [206 (44.30%)] were most often seen. The syndrome distribution were sequenced as intestinal damp heat syndrome [268 (57.63%)], dyspeptic retention in intestine and stomach syndrome [106 (22.80%)], cold-damp invading exterior syndrome [47 (10.11%)], Pi-Wei qi deficiency syndrome [23 (4.95%)], cold-damp disturbing Pi syndrome [21 (4.52%)]. The incidence ratio of intestinal damp heat syndrome was the highest in autumn (P < 0.01), while that of cold-damp invading exterior syndrome was the highest in winter (P < 0.01). Cold-damp disturbing Pi syndrome was more often seen in females than in males (P < 0.01), and its incidence ratio was the highest in autumn (P < 0.05). The incidence ratio of dyspeptic retention in intestine and stomach syndrome was the highest in winter (P < 0.01). CONCLUSIONS: Intestinal damp heat syndrome was the most often seen in acute infectious diarrhea. Incidence ratios of in- testinal damp heat syndrome and cold-damp disturbing Pi syndrome were higher in autumn, while those of cold-damp invading exterior syndrome and dyspeptic retention in intestine and stomach syndrome were higher in winter. Cold-damp disturbing Pi syndrome was more often seen in females.

Effects of Hemerocallis citrine baroni flavonids on CCl4-induced liver fibrosis of rats / 药学学报

This study is designed to explore the possible effects of Hemerocallis citrina baroni flavonids (HCBF) on liver fibrosis induced by CCl4 in rats. The liver fibrosis model was induced by CCl4, and HCBF were administered by gastric perfusion at 25 and 50 mg x kg(-1) qd for 50 days, while the contents of alanine transaminase (ALT), aspartate aminotransferase (AST), gamma glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), superoxide dismutase (SOD), maleic dialdehyde (MDA) and transforming growth factor-β1 (TGF-β1) were measured and the contents of PINP were measured in liver tissue, and the expression of TGF-β1 were observed by immunohistochemisty and Western blot. The pathological changes of liver tissue were examined by HE. The results showed that HCBF (25, 50 mg x kg(-1)) improved the liver function significantly through reducing the level of ALT, AST, GGT and ALP (P < 0.05 or P < 0.01), and increasing the content of SOD (P < 0.01), while reducing the content of MDA (P < 0.05 or P < 0.01), the expression of TGF-β1 (P < 0.05) and the content of PINP (P < 0.05). The results suggest that HCBF (25, 50 mg x kg(-1)) may inhibit the liver injury induced by CCl4 by decreasing the oxidative stress.

Analysis of poly-ß-hydroxyalkonates (PHA) during the enhanced biological phosphorus removal process using FTIR spectroscopy.

Enhanced biological phosphorus removal (EBPR) is the main phosphorus removal technique for wastewater treatment. During the anaerobic-aerobic alternative process, the activated sludge experienced the anaerobic storage of polyhydroxy-ß-alkonates (PHA) and aerobic degradation, corresponding the infrared peak intensity of sludge at 1 740 cm(-1) increased in the aerobic phase and declined in the anaerobic phase. Compared with PHA standard, this peak was indentified to attribute the carbonyl of PHA. The overlapping peaks of PHA, protein I and II bands were separated using Gaussian peak fitting method. The infrared peak area ratios of PHA versus protein I had a good relationship with the PHA contents measured by gas chromatography, and the correlation coefficient was 0.873. Thus, the ratio of the peak area of PHA versus protein I can be considered as the indicator of the PHA content in the sludge. The infrared spectra of 1 480-1 780 cm(-1) was selected, normalized and transferred to the absorption data. Combined with the chromatography analysis of PHA content in the sludge sample, a model between the Fourier-transform infrared spectroscopy (ETIR) spectra of the sludge and PHA content was established, which could be used for the prediction of the PHA content in the unknown sample. The PHA content in the sludge sample could be acquired by the infrared spectra of the sludge sample and the established model, and the values fitted well with the results obtained from chromatograph. The results would provide a novel analysis method for the rapid characterization and quantitative determination of the intracellular PHA content in the activated sludge.

Anticancer effects of Huaier are associated with down-regulation of P53.

This study was designed to explore the mechanism of Huaier anticancer effects on experimental hepatocellular cancer (HCC) development. Seventy five rats were divided into 5 groups, administered N-nitrosodiethylamine (groups B, C, D and E) or natural saline (group A). Rats in group C and E were also given Huaier. At the 15 week sacrifice point, the HCC incidence of group C was lower than group correlating with serum AFP. The serum ALT concentration (98.9% greater) and P53 mRNA levels (23.2%) were higher in Group B than group C. Longer term survival rates between group D and E were not significantly different. Huaier can protect liver from chemical injury and furthermore HCC development, possibly with involvement of down-regulation of P53.

Hepatoprotective effects of marine and kuhuang in liver transplant recipients.

We aimed to assess the effects of traditional Chinese medicine; marine (MT) and kuhuang (KH), either alone or in combination, on the early graft function of the recipients and overall patient survival rate after liver transplantation (LT) by using diammonium glycyrrhizinate (DG) as a positive control. A total of 151 subjects undergoing LT were included in this prospective study. According to the different regimens given in the first two post-transplant weeks, they were divided into DG group (n = 49), DG + KH group (n = 36), MT group (n = 42) and MT + KH group (n = 24). The graft function in the early post-transplant period and patient survival rate were examined. During the first two post-transplant weeks, there was no significant difference in total bilirubin, alanine transaminase, aspartate transaminase, serum creatinine, and prothrombin time between MT group and DG group. Patient survivals in these two groups were also similar. Compared to DG group, DG + KH group showed a significantly lower total bilirubin value on post-transplant day 5 (3.2 +/- 2.1 mg/dL vs. 5.7 +/- 5.6 mg/dL, p < 0.01) and day 7 (2.8 +/- 1.8 mg/dL vs. 5.8 +/- 6.1 mg/dL, p < 0.01), and higher patient survival. There was no significant difference between DG + KH group and MT + KH group. In conclusion, MT provides an alternative to DG after LT. The combination of MT and KH is highly effective in decreasing the total blirubin in the early post-transplant period and improving patient survival.
