Effects of "Xuetangping", a herbal prescription composed of Radix Astragali, Radix Trichosanthis, Rhizoma Dioscoreae, Fructus Corni, and Radix Salviae Miltiorrizae, on serum sugar of mice or rats with diabetes mellitus induced by alloxan were studied. The result showed that "Xuetangping" (2.5g/kg, ig qd 7d or 14d ) lowered serum sugar in diabetic mice but not in normal mice.Xuetangpinec 1.5g/kg,ig qd 7d or 14d in diabetic in a dose and time dependent manner. While 14d, "Xuetangping" also decreased the value of serum lipid and the content of serum lipid peroxide. This result suggest that antiperoxide activity of this Chinese herbal formulation may be related to its reduction in serum sugar

ObjectiveTo explore the effect of home visit based on empowerment education on psychotic symptoms， self-management ability and well-being of schizophrenia patients in home rehabilitation. MethodsA total of 87 cases of schizophrenia patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） and were recovering at home in Caiba town， Yibin city from January to July 2021 were selected by random sampling method as research subjects. They were divided into experimental group （n=43） and control group （n=44） according to the random number table method. The two groups received routine family visits， and the experimental group received family visits based on empowerment education. The intervention cycle of the two groups was 6 months. Before and after the intervention， the severity of psychotic symptoms， self-management ability and well-being of the patients in the two groups were assessed with the Brief Psychiatric Rating Scale （BPRS）， the Schizophrenia Self-Management Instrument Scale （SSMIS） and the Index of Well-Being Scale （IWB）. ResultsAfter intervention， the intra group comparison showed that the BPRS score in the experimental group was lower than that before the intervention （t=4.550， P<0.01）， the SSMIS scores in both groups were higher than those before intervention （t=-17.107， -6.367， P<0.01）， and the IWB score in the experimental group was higher than that before intervention （t=-9.239， P<0.01）. The comparison between groups showed that the BPRS score of the experimental group was lower than that of the control group， and the SSMIS and IWB scores were higher than those of the control group （t=-3.899， 10.564， 9.690， P<0.01）. ConclusionThe implementation of family visit based on empowerment education may help to improve the psychotic symptoms of home rehabilitation schizophrenia， and improve their self-management ability and well-being.

Objective To investigate the effect of dexmedetomidine and small dose of ketamine on the hyperalgesia and brain-derived neurotrophic factor (BDNF) mRNA in the spinal cord of rats with neuropathic pain.Methods Forty-five male Sprague-Dawley rats,weighing 240-270 g,were randomly divided into 5 groups (n =9 each):sham operation group (group S),spinal nerve injury (SNI) group,ketamine group (group K),dexmedetomidine group (group D) and dexmedetomidine + ketamine group (group K+ D).The animals were anesthetized with intraperitoneal 10% chloral hydrate 400 mg/kg.SNI was produced by exposing the sciatic nerve and its branches and ligation and transection of tibial nerve and common fibular nerve in groups SNI,K,D and K + D.In S group,the sciatic nerves and its branches were only exposed but not ligated.In groups D,K and K + D,dexmedetomidine 40 μg/kg (2 ml),ketamine 10 mg/kg (2 ml) and mixture of dexmedetomidine 20μg/kg + ketamine 5 mg/kg (2 ml) were injected intraperitoneally,respectively,once a day for 21 consecutive days starting from 24 h after successful SNI surgery.While the equal volume of normal saline 2 ml was injected instead in S and SNI groups.The paw withdrawal threshold to mechanical stimuli (PWT) was measured at 1 day before surgery,and 3,7,14 and 21 days after surgery.Three rats were sacrificed after measurement of pain threshold at 1 day before surgery,and 7 and 21 days after surgery and the lumbar segments (L4-6) of the spinal cord were removed for determination of BDNF mRNA expression in spinal dorsal horn by real time PCR.Results Compared with group S,the PWT was significantly decreased,and the expression of BDNF mRNA in spinal dorsal horn was up-regulated after surgery in groups SNI,K,D and K + D (P ＜ 0.05).The PWT was significantly higher,and the expression of BDNF mRNA in spinal dorsal horn was lower after surgery in groups K,D and K + D than in group SNI,and in group K + D than in groups K and D (P ＜ 0.05).Conclusion The combination of dexmedetomidine and small dose of ketamine produces a synergistic antinociception in rats with neuropathic pain,and direct or indirect inhibition of BDNF mRNA expression in spinal dorsal horn is involved in the underlying mechanism.

Objective To investigate the clinical effect of butylphthalide combined with naloxone in the treatment of elderly patients with cerebral hemorrhage.Methods A total of one hundred and thirty elderly patients with cerebral hemorrhage were selected in North China University of Science and Technology Affiliated Hospital from December 2012 to December 2014,and were randomly divided into two groups,each group 65 cases.Naloxone was used in the control group,while the observation group adopted butylphthalide combined with naloxone in its treatment.The curative effects were compared between two groups.Results After treatment,homocysteine,C reactive protein,hypoxia inducible factor,neurological function defect score were all significantly decreased in two groups (P<0.05).Homocysteine,C reactive protein,hypoxia inducible factor and neurological function defect score in the observation group were much lower than those of the control group ((10.2±1.3) μmol/L vs.(14.0±1.8) μmol/L,(3.9±1.1) mg/L vs.(6.9±1.4) mg/L,(51.6±10.3) pg/ml vs.(82.5±17.6) pg/ml,(3.7±1.0) points vs.(4.4±0.9) points,t=7.134,10.692,9.078,4.892,P<0.05).The total effective rate in the observation group was significantly higher than that of the control group (98.5% vs.89.2%,χ2=4.795,P<0.05).Compared the complications in two groups,the differences were not statistically significant (P>0.05).Conclusion Butylphthalide combined with naloxone is effective in the treatment of elderly patients with cerebral hemorrhage,which can significantly improve their clinical signs and neurological function.

Objective To study the correlation between small intestinal bacterial overgrowth (SIBO) and plasma endotoxin,platelet-derived growth factor(PDGF)level,and levels of serum hyaluronic acid (HA),laminin(LN),N-terminal procollagen Ⅲ peptide(PⅢNP)and type Ⅳ collagen(Ⅳ.C). Methods Lactulose hydrogen breath test (LHBT) was performed in 64 patients with chronic liver disease. Plasma endotoxin was measured with Limulus test, plasma PDGF was tested with ABC-enzyme-linked immunosorbent assay,serum HA,LN,PⅢNP and Ⅳ.C were tested by radioimmunoassay(RIA) in the patients. The relationship between SIBO and plasma endotoxin, PDGF and HA,LN,PⅢNP and Ⅳ.C levels were analyzed. Results Positive LHBT suggesting the existence of SIBO were observed in 22 patients(34.4%). Plasma endotoxin[(62?19) pg/ml vs.(31?13) pg/ml] and PDGF [(211?77) pg/ml vs.(136?57) pg/ml] levels were significantly higher in patients with SIBO than those in patients without SIBO (P

Objective To evaluate the diagnostic value of TSSC1 in glioma patients and its influence on cell biologi-cal behavior of glioma U87 cells. Methods RT-PCR and Western blot were used to examine the expression of TSSC1 in glioma samples, including 80 normal paraneoplastic tissues and 80 primary tumors. MTT and transwell were used to analyze the effect of TSSC1 knockout on proliferation, migration, and invasion in U87 cells. Results TSSC1 is down-regulated in glioma compared to its paraneoplastic counterparts and negatively related to higher grade. Furthermore, knockdown of TSSC1 expression results in increased proliferation, migration and invasion in U87 cells in vitro. Conclusion Our results may worked as a marker for early diagnosis and prognosis of glioma.

Objective To investigate the effect of mechanical thrombectomy device Solitaire AB for the treatment of distal occlusion of the intracranial artery caused acute anterior circulation ischemic stroke. Methods The clinical data of 9 patients with arterial occlusion of distal anterior circulation treated by using the Solitaire AB thrombectomy device were analyzed retrospectively. Seven of them had M2 middle cerebral artery occlusion and 2 had A3 occlusion. Their clinical features,imaging data,treatment,and the results of 3-month clinical follow-up were analyzed. The effectiveness of treatment was evaluated through the recanalization rate after stent thrombectomy,the National Institutes of Health Stroke Scale (NIHSS)scores before and after treatment,the modified Rankin scale (mRS)scores,and the 3-month clinical follow-up results. The surgery-related complications and mortality of patients were used to evaluate the safety of the treatment. Results (1 )Of the 9 intracranial arterial occlusions,8 were recanalized successfully. The modified thrombolysis in cerebral infarction (mTICI)was 2b or grade 3. (2)The NIHSS score median 9. 5 (3. 0,15. 5)at discharge dropped significantly compared with 19. 0 (16. 0,22. 0)before procedure. (Z=2. 703,P=0. 007). No permanent complications related to operation occurred. Four of the recanalized patients had good prognosis (mRS 0-1)and 4 had disability (mRS 3-4 ). The mRS score of one non-recanalized patient was 4 at the 3 months follow-up. Conclusion The embolectomy effect is good whom using Solitaire AB device for acute occlusion occurred in the intracranial artery M2 or A3 segment. Its efficacy,safety,and indications still need to be further explored in a larger sample controlled trial.
