Cognitive and Hippocampal Changes in Older Adults With Subjective Cognitive Decline After Acupuncture Intervention.

OBJECTIVE: Converging evidence indicates that subjective cognitive decline (SCD) could be an early indicator of dementia. The hippocampus is the earliest affected region during the progression of cognitive impairment. However, little is known about whether and how acupuncture change the hippocampal structure and function of SCD individuals. METHODS: Here, we used multi-modal MRI to reveal the mechanism of acupuncture in treating SCD. Seventy-two older participants were randomized into acupuncture or sham acupuncture group and treated for 12 weeks. RESULTS: At the end of the intervention, compared to sham acupuncture, participants with acupuncture treatment showed improvement in composite Z score from multi-domain neuropsychological tests, as well as increased hippocampal volume and functional connectivity. Moreover, the greater white matter integrity of the fornix, which is the major output tract of the hippocampus, was shown in the acupuncture group. CONCLUSION: These findings suggest that acupuncture may improve the cognitive function of SCD individuals, and increase hippocampal volume on the regional level and enhance the structural and functional connectivity of hippocampus on the connective level.

Dauricine attenuates Oct4/sonic hedgehog co-activated stemness and induces reactive oxygen species-mediated mitochondrial apoptosis via AKT/ß-catenin signaling in human neuroblastoma and glioblastoma stem-like cells.

Neuroblastoma and glioblastoma are primary malignant tumors of the nervous system, with frequent relapse and limited clinical therapeutic drugs. The failure of their treatment is due to the tumor cells exhibiting cancer stem-like cells (CSLCs) properties. Octamer binding transcription factor 4 (Oct4) is involved in mediating CSLCs, our previous work found that Oct4-driven reprogramming of astrocytes into induced neural stem cells was potentiated with continuous sonic hedgehog (Shh) stimulation. In this study, we aimed to study the importance of Oct4 and Shh combination in the stemness properties induction of neuroblastoma and glioblastoma cells, and evaluate the anti-stemness effect of dauricine (DAU), a natural product of bis-benzylisoquinoline alkaloid. The effect of Oct4 and Shh co-activation on cancer stemness was evaluated by tumor spheres formation model and flow cytometry analysis. Then the effects of DAU on SH-SY5Y and T98-G cells were assessed by the MTT, colony formation, and tumor spheres formation model. DAU acts on Oct4 were verified using the Western blotting, MTT, and so on. Mechanistic studies were explored by siRNA transfection assay, Western blotting, and flow cytometry analysis. We identified that Shh effectively improved Oct4-mediated generation of stemness in SH-SY5Y and T98-G cells, and Oct4 and Shh co-activation promoted cell growth, the resistance of apoptosis. In addition, DAU, a natural product, was found to be able to attenuate Oct4/Shh co-activated stemness and induce cell cycle arrest and apoptosis via blocking AKT/ß-catenin signaling in neuroblastoma and glioblastoma, which contributed to the neuroblastoma and glioblastoma cells growth inhibition by DAU. In summary, our results indicated that the treatment of DAU may be served as a potential therapeutic method in neuroblastoma and glioblastoma.

Cantharidin induces apoptosis of human triple negative breast cancer cells through mir-607-mediated downregulation of EGFR.

BACKGROUND: Triple negative breast cancer (TNBC) is a major subtype of breast cancer, with limited therapeutic drugs in clinical. Epidermal growth factor receptor (EGFR) is reported to be overexpressed in various TNBC cells. Cantharidin is an effective ingredient in many clinical traditional Chinese medicine preparations, such as Delisheng injection, Aidi injection, Disodium cantharidinate and vitamin B6 injection. Previous studies showed that cantharidin had satisfactory pharmacological activity on a variety of tumors. In this study, we aimed to study the therapeutic potential of cantharidin for TNBC treatment by targeting EGFR, and expound its novel regulator miR-607. METHODS: The effect of cantharidin on breast cancer in vivo was evaluated by 4T1 mice model. Then the effects of cantharidin on TNBC cells was assessed by the MTT, colony formation, and AnnexinV-PE/7AAD staining. Cantharidin acts on EGFR were verified using the cell membrane chromatography, RT-PCR, Western blotting, MTT, and so on. Mechanistic studies were explored by dual-luciferase report assay, RT-PCR, western blotting, and immunofluorescence staining assay. RESULTS: Cantharidin inhibited TNBC cell growth and induce apoptosis by targeting EGFR. miR-607 was a novel EGFR regulator and exhibited suppressive functions on TNBC cell behaviors. Mechanistic study showed that cantharidin blocked the downstream PI3K/AKT/mTOR and ERK/MAPK signaling pathway. CONCLUSION: Our results revealed that cantharidin may be served as a potential candidate for TNBC treatment by miR-607-mediated downregulation of EGFR.

["Houxi (SI 3) communicating the governor vessel" verified with the infrared thermal imaging technology].

OBJECTIVE: To compare the effect on facial acupoint temperature between acupuncture at Houxi (SI 3) and Dazhui (GV 14) so as to verify "Houxi (SI 3) communicating the governor vessel" based on the infrared thermal imaging technology. METHODS: Thirty-five healthy subjects (5 cases dropped off) were collected and before-after study in the same subject was adopted. The subjects were successively assigned into a sham-acupuncture group, a Houxi group, a Wangu group and a Dazhui group. Sham-acupuncture at Houxi (SI 3) on the left, acupuncture at Houxi (SI 3) on the left, Wangu (SI 4) on the left and Dazhui (GV 14) were given respectively. One intervention was given and the needles were retained for 30 min in each group. 30 min before and after acupuncture, the infrared thermal images of the face were collected, and the facial temperature was compared among the following 5 acupoints, i.e. Yintang (GV 24+), Suliao (GV 25), Shuigou (GV 26), Duiduan (GV 27) and Chengjiang (CV 24). RESULTS: After acupuncture, the facial temperature at Yintang (GV 24+) and Chengjiang (CV 24) was increased compared before acupuncture in the sham-acupuncture group (P<0.01, P<0.05). The facial temperature at Suliao (GV 25) in the Houxi group was reduced after acupuncture (P<0.05). In the Wangu group, the temperature at Yintang (GV 24+) was increased compared before acupuncture (P<0.01). The facial temperature was increased at Duiduan (GV 27) and Chengjiang (CV 24) compared before acupuncture in the Dazhui group (P<0.01, P<0.05). The differences of facial temperature at Chengjiang (CV 24) and Suliao (GV 25) after acupuncture were larger than before acupuncture in the Houxi group and the Dazhui group (P<0.01). In comparison with the temperature at Suliao (GV 25) of the same group, the differences of facial temperature before and after acupuncture at Yintang (GV 24+), Shuigou (GV 26), Duiduan (GV 27) and Chengjiang (CV 24) were increased in the Houxi group (P<0.01, P<0.05); while, the increase was also obtained at Yintang (GV 24+), Shuigou (GV 26), Duiduan (GV 27) and Chengjiang (CV 24) in the Dazhui group (P<0.05, P<0.01). The difference of facial temperature at Yintang (GV 24+) before and after acupuncture was increased compared with Suliao (GV 25) in the Wangu group (P<0.05). CONCLUSION: Acupuncture at Houxi (SI 3) generates a similar thermal effect as Dazhui (GV 14). It regulates and dissipates the core temperature to "govern the yang qi of the whole body".

Evaluation of individualized treatment of nonproliferative diabetic retinopathy: a multicenter, randomized, parallel-controlled study.

OBJECTIVE: To evaluate the differences in the efficacy of stationary treatment and individualized treatment for patients with nonproliferative diabetic retinopathy (NPDR). METHODS: This study was a randomized, controlled, multicenter clinical trial. Participants with NPDR were randomized into the stationary treatment group or the individualized treatment group. The stationary treatment group was given the basic treatment and Qiming granules, and the individualized treatment group was given the basic treatment, Qiming granules, and individualized Chinese herbal medicines over a 12-week period. The individualized therapeutic formula was also changed over time to adjust to the changes in the clinical presentation of the patient. We conducted observations of fundus retinal exudation and hemorrhage, visual acuity, Traditional Chinese Medicine symptom scores and other indicators. RESULTS: A total of 140 participants with NPDR were randomized into the stationary treatment group or the individualized treatment group, and 132 participants completed this study. Following the 12-week treatment, significant improvements in both primary and secondary outcomes were observed in the stationary and individualized treatment groups. No remarkable difference in the primary outcomes between the two groups was observed. However, there was a significant difference in the Traditional Chinese Medicine symptom scores (18 ± 7 vs 15 ± 6; P < 0.05). There were no severe adverse effects. CONCLUSION: Compared with stationary treatment, individualized treatment is more effective at relieving the Traditional Chinese Medicine symptoms and improving vision and fundus lesions at 12 weeks post treatment.

Synergistic effect of toosendanin and regorafenib against cell proliferation and migration by regulating WWOX signaling pathway in hepatocellular carcinoma.

Regorafenib (RGF), a second-line multi-kinase inhibitor in the treatment of HCC (hepatocellular carcinoma) after sorafenib failure, exposes to the risk of drug resistance and subsequent progression of HCC patients. Toosendanin (TSN), a triterpenoid has presented excellent inhibition on several tumors. The purpose of this study is to investigate the inhibitory effect of the combination of TSN and RGF on HCC cells. We identified that TSN and RGF combination (TRC) synergistically inhibited the proliferation and migration of MHCC-97L cells. The upregulation of WWOX (WW-domain containing oxidoreductase) played a vital role in the HCC cell growth treated with TRC. TRC suppressed the phosphorylation of Stat3 and expression of DVL2, negatively regulated the activity of ß-catenin by promoting the phosphorylation of GSK3ß. In addition, the intranuclear proteins, including MMP2, MMP9, and C-MYC were significantly inhibited by TRC. The in vivo xenograft models confirmed that TRC effectually prevented the tumor growth through upregulating WWOX. Therefore, the treatment of TRC may be a potential solution of RGF resistance and promising therapeutic method in malignant HCC.

WWOX activation by toosendanin suppresses hepatocellular carcinoma metastasis through JAK2/Stat3 and Wnt/ß-catenin signaling.

Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related deaths worldwide. Loss of WW-domain containing oxidoreductase (WWOX) has been proven to be associated with malignant metastasis in patients with HCC. In this study, by using a non-biased CRISPR knockout genetic screen targeting 19,050 human genes, we found that toosendanin (TSN) is a novel druggable WWOX candidate agonist for metastatic HCC patients. We also found that TSN exhibited significant anti-proliferative and anti-metastatic effects on HCC cells in a WWOX-dependent manner. Overexpression and knockdown of WWOX in vitro and in vivo confirmed that the suppression of HCC by TSN involved WWOX. TSN regulated Stat3, DVL2, and GSK3ß by transforming their interactions with WWOX as demonstrated by a Co-IP assay. TSN accelerated the degradation of ß-catenin by promoting the function of APC, AXIN1, CK1, and GSK3ß complex. Nuclear translocation of p-Stat3 Y705 and ß-catenin was impeded by the TSN-induced blockade of JAK2/Stat3 and Wnt/ß-catenin signaling, accompanied by the inhibition of MMPs and C-MYC.

Different Degree Centrality Changes in the Brain after Acupuncture on Contralateral or Ipsilateral Acupoint in Patients with Chronic Shoulder Pain: A Resting-State fMRI Study.

Chronic shoulder pain (CSP) is the third most common musculoskeletal problem. For maximum treatment effectiveness, most acupuncturists usually choose acupoint in the nonpainful side, to alleviate pain or improve shoulder function. This method is named opposite needling, which means acupuncture points on the right side are selected for diseases on the left side and vice versa. However, the underlying neural mechanisms related to treatment are currently unclear. The purpose of this study was to determine whether different mechanisms were observed with contralateral and ipsilateral acupuncture at Tiaokou (ST 38) in patients with unilateral CSP. Twenty-four patients were randomized to the contralateral acupuncture group (contra-group) and the ipsilateral acupuncture group (ipsi-group). The patients received one acupuncture treatment session at ST 38 on the nonpainful or painful sides, respectively. Before and after acupuncture treatment, they underwent functional magnetic resonance scanning. The treatment-related changes in degree centrality (DC) maps were compared between the two groups. We found alleviated pain and improved shoulder function in both groups, but better shoulder functional improvement was observed in the contra-group. Increased DC in the anterior/paracingulate cortex and decreased DC in bilateral postcentral gyri were found in the contra-group, while decreased DC in the bilateral cerebellum and right thalamus was observed in the ipsi-group. Furthermore, the DC value in the bilateral anterior/paracingulate cortex was positively correlated with the treatment-related change in the Constant-Murley score. The current study reveals different changes of DC patterns after acupuncture at contralateral or ipsilateral ST 38 in patients with CSP. Our findings support the hypothesis of acupoint specificity and provide the evidence for acupuncturists to select acupoints for CSP.

Effect of acupuncture on hormone level in patients with gastrointestinal dysfunction after general anesthesia: A study protocol for a randomized controlled trial.

BACKGROUND: Postoperative gastrointestinal dysfunction (PGD) refers to one of the common postoperative complications. Acupuncture can facilitate the recovery of PGD, whereas no therapeutic schedule of acupuncture has been internationally recognized for treating PGD. In the present study, a scientific trial protocol has been proposed to verify the feasibility of acupuncture in treating gastrointestinal dysfunction after laparoscopic cholecystectomy under general anesthesia. We conduct this protocol to investigate whether acupuncture recovery gastrointestinal dysfunction by influencing the expression of gastrointestinal hormone. METHOD: The present study refers to a randomized, evaluator blinded, controlled, multi-center clinical trial; it was designed complying with the Consolidated Standards of Reporting Trials (CONSORT 2010) as well as the Standard for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA). The subjects will be taken from the inpatients having undergone laparoscopic surgery of Mianyang Affiliated Hospital of Chengdu University of traditional Chinese medicine, Mianyang Third Hospital and Mianyang Anzhou Hospital. Based on the random number yielded using SPSS 25.0 software, the qualified subjects will be randomly classified to the experimental group and the control group. Therapies will be performed 30 min once after operation, the experimental group will be treated with acupuncture, while the control group will receive intravenous injection of granisetron. The major outcome will be the time to first flatus, and the secondary outcomes will include the time to first defecation, abdominal pain, dosage of analgesia pump, abdominal distention, nausea, vomiting, gastrointestinal hormone, as well as mental state. The efficacy and safety of acupuncture will be also assessed following the principle of Good Clinical Practice (GCP). DISCUSS: A standardized and scientific clinical trial is conducted to assess the efficacy and safety of acupuncture for gastrointestinal dysfunction after laparoscopic cholecystectomy under general anesthesia. The aim is to objectively evidence and improves the clinical practice of acupoint prescription, as an attempt to promote the clinical application of this technology.

Efficacy and neural mechanism of acupuncture treatment in older adults with subjective cognitive decline: study protocol for a randomised controlled clinical trial.

INTRODUCTION: Subjective cognitive decline (SCD) refers to individuals' perceived decline in memory and/or other cognitive abilities relative to their previous level of performance, while objective neuropsychological deficits are not observed. SCD may represent a preclinical phase of Alzheimer's disease. At this very early stage of decline, intervention could slow the rate of incipient decline to prolong and preserve cognitive and functional abilities. However, there is no effective treatment recommended for individuals with SCD. Acupuncture, as a non-pharmacological intervention, has been widely employed for patients with cognitive disorders. METHODS AND ANALYSIS: The proposed study is a randomised, assessor-blinded and placebo-controlled study that investigates the efficacy and mechanism of acupuncture in SCD. Sixty patients with SCD will be randomly allocated either into an acupuncture group or a sham acupuncture group. They will receive 24 sessions of real acupuncture treatment or identical treatment sessions using a placebo needle. Global cognitive changes based on a multidomain neuropsychological test battery will be evaluated to detect the clinical efficacy of acupuncture treatment at baseline and end of treatment. MRI scans will be used to explore acupuncture-related neuroplasticity changes. Correlation analyses will be performed to investigate the relationships between the changes in brain function and symptom improvement. ETHICS AND DISSEMINATION: The trial was approved by the research ethics committee. The results of the study will be published in a peer-reviewed academic journal and will also be disseminated electronically through conference presentations. TRIAL REGISTRATION NUMBER: NCT03444896.

Amaryllidaceae alkaloids from Crinum latifolium with cytotoxic, antimicrobial, antioxidant, and anti-inflammatory activities.

Four novel and potently bioactive Amaryllidaceae alkaloids, 4,8-dimethoxy-cripowellin C (1), 4,8-dimethoxy-cripowellin D (2), 9-methoxy-cripowellin B (3), and 4-methoxy-8-hydroxy-cripowellin B (4), together with one known alkaloid, cripowellin C (5) were isolated from the 95% EtOH extract of the bulbs of Crinum latifolium. Structural elucidation of all the compounds were performed by spectral methods such as 1D and 2D (1H-1H COSY, HMQC, and HMBC) NMR as well as spectroscopy high resolution mass spectrometry. All isolates were in vitro evaluated for their cytotoxic activity against seven lung cancer cell lines, in addition to antimicrobial activity for eight bacteria, scavenging potential using ABTS·+ and DPPH test, and anti-inflammatory activity for Cox-1 and Cox-2 which had not previously been tested for crinane-type alkaloids with the cleavage between C-1 and C-13. Consequently, alkaloids 1-5 exhibited potent cytotoxicity against all of seven tested tumor cell lines with (IC50 < 30 nM). Alkaloids 3 and 4 displayed the significant antimicrobial activity with IC50 values <0.50 mM and antioxidant activity in the ABTS·+ and DPPH test. Additionally, Alkaloids 1-5 exhibited comparable inhibition of Cox-1 (>64%) and Cox-2 (>90%) with positive control.

Stationary Treatment Compared with Individualized Chinese Medicine for Type 2 Diabetes Patients with Microvascular Complications: Study Protocol for a Randomized Controlled Trial.

BACKGROUND: Microvascular complications in type 2 diabetes (T2DM), including diabatic retinopathy (DR), diabetic kidney disease (DKD), diabetic peripheral neuropathy (DPN) are the leading causes of visual loss, end-stage renal disease or amputation, while the current therapies are still unsatisfactory. Chinese medicine (CM) has been widely used for treating diabetic mellitus. However, most of the previous studies focused on the single complication. The role of CM treatment in T2DM patients with 2 or multiple microvascular complications is not clear. OBJECTIVE: To appraise the curative effect of CM in T2DM patients with 2 or multiple microvascular complications, and to compare the effects of stationary treatment and individualized treatment in T2DM patients with microvascular complications. METHODS: This trial will be an 8-center, randomized, controlled study with 8 parallel groups. A total of 432 patients will be randomized to 8 groups: DR study group (32 cases) and a corresponding control group (32 cases), DR+DKD study group (64 cases) and a corresponding control group (64 cases), DR+DPN study group (64 cases) and a corresponding control group (64 cases), DR+DKD+DPN study group (56 cases) and a corresponding control group (56 cases). The control group will receive stationary treatment, and the study group will receive individualized treatment based on CM syndrome differentiation in addition to stationary treatment. The study duration will be 50 weeks, comprising a 2-week run-in period, 24 weeks of intervention, and 24 weeks of follow-up. The outcomes will assess efficacy of treatment, improvement in CM symptoms, safety assessments, adherence to the treatment, and adverse events. CONCLUSION: This study will provide evidence of evidence-based medicine for CM treatment in two or multiple microvascular complications caused by T2DM. (Registration No. ChiCTR-IPR-15007072).

Different mechanisms of contralateral- or ipsilateral-acupuncture to modulate the brain activity in patients with unilateral chronic shoulder pain: a pilot fMRI study.

BACKGROUND: Chronic shoulder pain (CSP) is a common disease causing pain and functional limitation, which is highly prevalent and has substantial negative effects on the quality of life. Acupuncture has gained popularity and has been accepted gradually by many countries because it can successfully treat patients with chronic pain, but the specific brain mechanisms under acupuncture treatment for CSP remain unclear. Therefore, in this study, we aimed to 1) compare the clinical effects between acupuncture at the contralateral and ipsilateral Tiaokou (ST 38) point in patients with unilateral shoulder pain and 2) explore how contralateral- and ipsilateral-acupuncture modulates the regional homogeneity (ReHo) of patients with CSP. PATIENTS AND METHODS: This was a pilot functional magnetic resonance imaging (fMRI) trial. Twenty-four patients with CSP were recruited and randomized to the contralateral acupuncture group (contra-group) and the ipsilateral acupuncture group (ipsi-group). All patients completed resting-state functional magnetic resonance imaging (fMRI) scans before and after acupuncture treatment. Shoulder pain intensity (visual analog scale [VAS]) and shoulder joint function (Constant-Murley score [CMS]) were used to evaluate clinical efficiency of treatment. ReHo was used to assess resting-state brain activity. RESULTS: We found clinical improvement in decreasing pain intensity and increasing shoulder function in both groups, and the mean objective shoulder functional improvement in contra-group was better than that in ipsi-group (p = 0.010). Interestingly, the brain mechanism of contra-acupuncture at ST 38 was distinguishable from ipsi-acupuncture regarding ReHo values. CONCLUSION: Anterior cingulate cortex (ACC) may play a direct role in the regulation of brain by the contralateral acupuncture at ST 38 in patients with shoulder pain. On the contrary, the pathway of brainstem-thalamus-cortex may be likely to work in mechanism of acupuncture at ipsilateral ST 38. SIGNIFICANCE: Our results indicate that the clinical effects and brain mechanisms are different between the stimulation given at contralateral and ipsilateral acupoints in patients with CSP and imply that the selection of either contralateral or ipsilateral acupuncture therapy to treat some chronic pain conditions is necessary.

[Correlation analysis on combined medication with of Xiyanping injection in treatment of lung infection in real world].

To analyze the regularity in combined medication with Xiyanping injection (Xiyanping for short) in the real world by as- sociation rules. Totally 5 822 patients using Xiyanping injection was collected from the 18 Class III Grade I hospitals nationwide to study the combined medication information of the patient with lung infection and make the analysis by using association rules and Apriori. According to the results, major drugs combined with Xiyanping in treatment of lung infection included compound amino acid, inosine, coenzyme A, cytidine triphosphate, vitamin C. Common drugs combined with Xiyanping can be divided into 5 categories: nutrition support therapy (vitamin C, compound amino acid) , coenzymes (coenzyme A, cytidine triphosphate, inosine), expectorants and antiasthmatics (ambroxol, salbutamol, doxofylline), hormones (dexamethasone, budesonide), antibiotics (mainly cefminox). The main combined medicines mostly conformed to the regularity for drugs treating lung infection. In addition, there were two most common medical combination models: the model for Xiyanping combined a single medicine is Xiyanping + nutrition support therapy, while the model for Xiyanping combined two or more than two medicines is Xiyanping + nutrition support therapy + coenzyme. Pharmacologically, Xiyanping is mostly combined with western medicines with similar pharmacological effects to substitute or supplement the antibiotic effect in treating lung infection. However, further studies shall be conducted for the safety and rationality of the combined medication based on clinical practices, in order to provide reference for clinical medication.

[Analysis of questionable allergic factors to parenterally administered salvianolate--a nested case control study using hospital information system data].

This study aims to assess if adverse drug reactions (ADRs) to parenterally administered salvianolate are allergic in origin. Hospital information system (HIS) data from 20 hospitals in China were used to carry out a retrospective nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving parenterally administered salvianolate. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on admission had a significant effect, P values was < 0.000 1 on suspected cases of allergic reactions in the first subgroup analysis. For the second subgroup analysis, we found condition on solvents had a significant effects, P values was 0.005 1 on suspected cases of allergic reactions. We also found that using other four injections at the same time as parenterally administered salvianolate could be risky factors in suspected cases of allergic reactions. For the second subgroup analysis combining using three injections could increase risks. However, further research for verification is required. This study can provide guidance for safe clinical practice in using parenterally administered salvianolate.

[Data analysis of electronic medical recored clinical changes in indexs of liver and kidney function when salvianolate injection is parenterally administered over extended period].

To understand the impact of salvianolate injection treatment of liver and kidney function using different from the hospital information system nationwide 18 large three hospitals (hospital information system, HIS) to extract using salvianolate age 18-80 years-old patient, a total of 10 470 cases, depending on the treatment used to have two times before and after treatment 7 d aspartate aminotransferase (AST), alanine aminotransferase patients (ALT), serum creatinine (Cr) and blood urea nitrogen (BUN) measurement indicators grouped according salvianolate continuous use different treatment patients were divided into two groups, continuous medication time > 14 d were defined as the observation group, ≤ 14 d were defined as the control group, continuous medication longer than 31 d were not included in the analysis. Each index number of the observation group and the control group were: ALT (268/1 465), AST (270/1 585), Cr (278/1 582), BUN (278/1 611). After using propensity score methods to balance two groups of covariates, based on unweighted logistic regression logistic regression propensity score weighting combined with propensity score weighting to adjust for covariates logistic regression of liver and kidney function in the two groups were analyzed. The results showed: three logistic regression analysis showed no likelihood of ALT, AST, Cr targets two groups of patients with abnormal statistically significant difference, continuous medication time > 14 d may increase the risk of abnormal BUN indicators, comprehensive analysis still can not explain use different treatment of patients salvianolate cause liver and kidney toxicity damage, still large prospective randomized controlled trials further study.

[Real-world study of effect on liver function of parenterally administered shuxuetong with different doses].

OBJECTIVE: To analyze the effect on liver function of parenterally administered Shuxuetong Injection with different doses. METHOD: The study is based on hospital information system (HIS) data. We group the cases by dose: The observation group receive a dose > 6 mL (recommended daily dose), the matched group receive the recommended dose. Chi-square test, logistic regression, logistic regression with propensity score, logistic regression with GBM propensity score were used to find the between group differences in ALT and AST after using parentyerally administered Shuxuetong injection. RESULT: All tests show that there were no significant differences between groups in AST or ALT after we control for confounding factors. CONCLUSION: Based on HIS data, there was no evidence to associate the use of Shuxuetong over the recommended dose and effects on liver function.

[Real world study of affect on liver function of overdose of salvianolate extract injection].

OBJECTIVE: To understand the affect on liver function of using salvianolate injection above the recommended dose. METHOD: Nationwide, research of hospital information system (HIS) data from 18 general hospitals comprising 14 191 patients was carried out. Two groups of patients were studied and their blood tests monitored before and after injections. One group received the recommended dose of 200 mg, the other exceeded it. To take into account group differences the propensity score method and logstic regression was used alongside liver function. RESULT: When salvianolate injection was administered above the recommended dose patients were more likely to have abnormal AST and ALT levels. However, the difference between the groups was not statistically significant. CONCLUSION: According to our data the affect of exceeding the recommended dose of salvianolate injection on liver function is not significant. However, monitoring of liver function should be carried out in clinic.

[Analysis of actual effects of combining xiyanping injection with vitamin C injection in treatment of upper respiratory tract infection].

OBJECTIVE: To investigate whether Xiyanping injection associated with vitamin C injection will improve the cure rate of upper respiratory tract infection compared to treatment with Xiyanping injection alone. METHOD: The analysis was based on hospital information system (HIS) data. Patients were divided into two groups according to whether he or she accepted the addition of vitamin C to treatment with Xiyanping injection. We used the propensity score to balance confounding factors, and made confounding factors which cannot be balanced by the propensity score to act as covariate variables. Then Logistic regression was used to evaluate the effectiveness of the two groups. RESULT: There was no significant difference between the 2 groups. CONCLUSION: Compared with Xiyanping injection alone, using vitamin C in combination does not improve the treatment effectiveness of upper respiratory tract infection.

Early hyperbaric oxygen therapy inhibits aquaporin 4 and adrenocorticotropic hormone expression in the pituitary gland of rabbits with blast-induced craniocerebral injury.

In the present study, rabbits were treated with hyperbaric oxygen for 1 hour after detonator-blast- induced craniocerebral injury. Immunohistochemistry showed significantly reduced aquaporin 4 expression and adrenocorticotropic hormone expression in the pituitary gland of rabbits with craniocerebral injury. Aquaporin 4 expression was positively correlated with adrenocorticotropic hormone expression. These findings indicate that early hyperbaric oxygen therapy may suppress adrenocorticotropic hormone secretion by inhibiting aquaporin 4 expression.
