Objective To explore the anti-convulsion action of histamine(HA) in the central system and treatment of histamine H3 receptor(H3R) antagonists to rat model with intractable epilepsy.Methods 88 Wistar rats(12-day-old) were randomly divided into three groups:normal control group,N-methyl-D-aspartate(NMDA) group and betahistine(BH) groups(including high and low dose BH groups).Wistar rats received an intraperitoneal NMDA administration to make animal model of intractable epilepsy at infant period and toddler age.After that,the rats were observed daily for latencies and incidences to two NMDA-dependent stereotypical behaviors.The HA content of each brain region was determined with fluorimetry,and H3R were evaluated with immunohistochemical method.Results The automatisms including tail twisting and emprosthotonus seizures of(12-17)-day-old rats were observed in NMDA and BH groups.The rats,aged 18-25 d,became quiet following automatisms rather than emprothotonic.Compared with NMDA group,BH groups had longer latencies and lower incidences of tail twisting and emprosthotonus(P0.05).Conclusion The NMDA-induced model is similar to the clinical manifest of human West syndrome.It is up to animal model of intractable epilepsy at infant period and toddler age.The HA content of brain region is negatively related with seizure incidence.H3R antagonists have certain therapeutic function to intractable epilepsy in rats at infant period and toddler age.

Objective To investigate the clinical and imaging features of mild encephalitis/encephalopathy with a reversible splenial lesion of corpus callosum (MERS) in children.Methods Four patients of MERS, who were diagnosed and treated in the First Hospital of Jilin University during 2013-2014, were collected retrospectively.Their clinical, laboratory, radiologic data and the related literatures were reviewed.Results Four patients onsetted as gastrointestinal symptom (3 cases) or respiratory (1 case) symptom, in accompany with disturbance of consciousness (3 cases of drowsiness, 1 case of lethargy), convulsions (4 cases), headache (1 case) as the main symptoms.Abnormal neurological signs included positive cervical resistance (3 cases), positive bilateral Babinski sign (3 cases), bilateral chemosis (2 cases).Laboratory test showed the average blood sodium was 131.6 mmol/L, while the cerebrospinal fluid test only showed abnormality in 1 case.In etiology examination, 2 cases showed human rotavirus antigen positive, and Mycoplasma pneumoniae antibody was found positive in 2 cases.Cranial MRI showed reversible lesion in the splenium of corpus callosum (patchy iso-or hypo-intensity on T1 WI and apparent diffusion coefficient, hyper-intensity on T2WI, FLAIR and DWI, clear boundary).After active treatment, clinical symptoms disappeared within 1 week, and cranial MRI lesions disappeared within 2 weeks.Conclusion The clinical presentations of MERS, which is a clinical-radiological syndrome, are sudden onset and mild, with characteristic changes in brain MRI and good prognosis.

Objective To investigate the efficacy and safety of oxcarbazepine (OXC) suspension for treating the 2 to 4 years old patients newly diagnosed as partial epilepsy.Methods A total of 62 patients between 2 to 4 years old diagnosed as partial epilepsy,selected from the outpatients of the pediatric neurology in the hospital from October 2009 to March 2011,were randomly divided into the experimental group of 32 patients and the control group of 30 patients.Experimental group:OXC suspension,the initial dose was 8-10 mg· kg-1 d-1,orally taking 2 times every day,increasing the dose by 10 mg · kg-1 d 1 once every 7 days to the complete control of the seizure,the target dose was 20-40 mg· kg-1 · d-1 Control group:oral administration of carbamazepine (CBZ) group,the initial dose was 5 mg· kg 1 · d-1,increasing the dose once every 5-7 days up to 10-15 mg · kg-1 · d-1,if necessary,the dose could be 20 mg · kg 1 d-1 to maintain.The observation period was 26 weeks.Results The rate of valid cases in OXC group after 13 weeks and 26 weeks were both 78.1％ (25/32),and the rate of non-attack cases were 53.l％ (17/32) and 50.0％ (16/32),respectively; the rate of valid cases in CBZ group after 13 weeks and 26 weeks were 76.7％ (23/30) and 70.0％ (21/30),respectively,and the rate of non-attack cases were 50.0％ (15/30) and 40.0％ (12/30) (x2 =0.022,0.004 ; P =0.883,0.947 respectively.).In the 26th week,the quit rate of OXC group was 6.2％,while the quit rate of CBZ group was 13.4％.The rates of adverse reactions of OXC and CBZ were 15.6％ and 26.7％,respectively,with no significant difference.Conclusion OXC suspension monotherapy for 2 to 4 years old patients with partial epilepsy was significant effective,and no significant difference when compared with carbamazepine group.The rate of the adverse reactions in the OXC group was relatively fewer,and the extent was slight.

Objective To study the expression of Galectin-3,CK19 and Ki-67 in the papillary thyroid carcinoma and papillary thyroid hyperplasia and to find the differential diagnostic makers. Methods A total of 200 cases, including 100 with papillary thyroid carcinoma and 100 papillary thyroid hyperplasia by Immunohistochemistry. Results The positive rates for Galectin-3,CK19 and Ki-67 in the papillary thyroid carcinoma were 100 %, 97 % and 93 %, which were significantly higher than those in the papillary thyroid hyperplasia (13 %, 31 %, 1 %) (P

Studies on the relationship between Helicobacter pylori infection and colorectal cancer have been controversial in recent years. The Chinese "eat-together system" dietary culture and the life style of family gathering result in a high infection rate of Helicobacter pylori, and the relationship between Helicobacter pylori and tumors has thereupon become one of the research hotspots. Studies have shown that Helicobacter pylori infection may promote the occurrence of colorectal precancerous lesions and colorectal cancer by inducing hypergastrinemia, destroying intestinal microecology, suppressing immune function and other ways. This article reviews the research progress on the relationship between Helicobacter pylori infection and colorectal cancer and its mechanism.

Objective To explore the preventive effect of twin-tube laryngeal mask airway on gastric lavage and aspiration pneumonia. Methods Between January 2015 and June 2017, 305 cases of poisoning coma patients were admitted to Emergency Department, The First Affiliated Hospital of Nanchang University. According to the inclusion criteria and exclusion criteria, 255 cases of poisoning coma patients were enrolled and randomly(random number) divided into 3 groups (n=85 in each group):group A (normal gastric lavage machine method), group B (gastric lavage endotracheal intubation), and group C (gastric lavage twin-tube laryngeal mask airway placement). Whether there was aspiration pneumonia within 12 hours after the onset was observed, and the length of hospital stay, hospitalization cost and mortality were recorded. The mean value of the two samples was compared with t test, and the four-grid data were checked by chi-square test. P<0.05 was statistically significant. Results Compared with group A, the incidence of aspiration pneumonia was significantly lower in group B and group C (group A 56.47％, group B 32.94％, group C 23.53％, P<0.01). Compared with group A, the length of hospital stay in group C was shorter [(3.39±2.12) d vs. (6.06±4.91) d,P<0.05], and the hospitalization cost was less [(25687.52±20803.44) yuan vs. (52213.91±37267.56)yuan,P<0.05]. There was no significant difference of mortality between the three groups (P>0.05).Compared with group B, the length of hospital stay in group C was shorter [(3.39±2.12) d vs.(5.51±4.37) d, P<0.05], and the hospitalization cost was less [(25687.52±20803.44)yuan vs.(50887.82±32399.76) yuan, P<0.05]. There was no significant difference of mortality between the three groups (P>0.05). Conclusions Twin-tube laryngeal mask airway for poisoning coma patients with gastric lavage, can not only ensures effective ventilation, but also reduces the probability of concurrent aspiration pneumonia, shortens hospital stay, and reduces hospitalization cost, but has no obvious effect on mortality.

BACKGROUND:Tissue flossing is a new injury prevention tool and auxiliary exercise training strategy.Tissue flossing can increase joint range of motion,improve athletic performance,and relieve pain,and is increasingly widely used in the field of sports and rehabilitation. OBJECTIVE:To review the mechanism of tissue flossing and its application in sports and rehabilitation to provide a reference for follow-up research. METHODS:"Tissue flossing;compression tissue flossing;floss band;voodoo flossband;blood flow restriction;shearing of fascia;musculoskeletal rehabilitation;sport injury"were used as Chinese and English search terms to search on the databases of CNKI,WanFang,VIP,PubMed and EBSCO databases.Relevant articles from January 2000 to October 2022 were retrieved,and 86 articles were finally included according to inclusion and exclusion criteria. RESULTS AND CONCLUSION:Tissue flossing intervention can improve lower limb joint motion,improve sprint and jump performance,promote joint injury rehabilitation,and relieve pain subjectively.However,tissue flossing intervention did not improve the range of motion of the upper limb.There is still controversy on the acute enhancement of lower limb muscle strength.It has a good tendency to improve lower limb balance and stability and improve mental state,but more studies are needed to confirm.The possible mechanisms of tissue flossing intervention are mainly fascia shear,pain gating,blood flow restriction and reperfusion,and compression.Tissue flossing is a useful treatment option that can provide important contributions in the future in the areas of sports training,sports injury prevention and rehabilitation,but more long-term in-depth studies are needed.

Objective: Percutaneous vertebroplasty (PVP) is currently the most common surgical procedure for unstable Kummell disease (KD), but cement loosening or displacement often occurs after PVP. We had been using percutaneous pediculoplasty (PPP) or a self-developed bone cement bridging screw system to avoid this severe complication. This study intends to compare these novel surgical procedures through a 2-year follow-up evaluation. Methods: From May 2017 to May 2021, 77 patients with single-level unstable KD were included in the PPP group, and 42 patients received the PVP-bone cement bridging screw system were included in the screw group. The changes in the vertebral body index (VBI), bisegmental Cobb angle, visual analogue scale (VAS) and Oswestry Disability Index (ODI) and the cement loosening rate and displacement rate at different follow-up time points were used to evaluate the clinical efficacy. Results: There was no significant difference in VBI or bisegmental Cobb angle between the 2 groups (p > 0.05) before operation, immediately after operation and at 6-month followup, while at 1-year and 2-year postoperative evaluations, the screw group had higher VBI and bisegmental Cobb angle than the PPP group (p < 0.05). Before operation, immediately after operation, at 6-month and 1-year follow-up, there was no significant difference in VAS or ODI score between the 2 groups (p > 0.05), while at 2-year follow-up, the screw group still had higher VAS and ODI scores than the PPP group (p < 0.05). No bone cement displacement occurred in both groups, but the rate of bone cement loosening was 14.29% in group PPP, and 0 in screw group (p < 0.05). Conclusion This 2-year follow-up study shows that the PVP-bone cement bridging screw system combined therapy had better midterm treatment efficacy than the PVP-PPP combined therapy in patients with unstable KD, and the bone cement bridging screw system is a preferred therapy with better anti cement loosening ability.
