Ictal semiology is essential for the pre-operative evaluation of candidates for epilepsy surgery. We propose an ictal sign of temporal lobe epilepsy (TLE) termed tonic-automotor (TA), defi ned as contralateral tonic spasm of upper limb associated with ipsilateral hand automotor seizure and often accompanied ipsilateral head turning. We assessed the occurrence and lateralizing/localizing value of TA in TLE, we analyzed 129 seizures in 41 patients with TLE: 90 seizures in 30 patients with TLE of hippocampal sclerosis (TLE/HS) and 39 seizures in 11 patients with TLE of other lesions (TLE/ non-HS). When compared with unilateral automotor seizure and unilateral tonic spasm, TA occurred more frequently in TLE/HS patients (40% vs 10% and 16.7%). In addition, 24 seizures in 12 patients with TA were observed only in TLE/HS patients and contralateral to the seizure focus based on the side of tonic spasm. However, there was no signifi cant difference in the TLE/HS between dominant side and nondominant side. In addition, TA sign occurred relatively early in the ictal phase. Thus, TA may be a more reliable lateralizing sign of epileptogenic zone and a semiologic marker of TLE/ HS patients.

OBJECTIVETo establish a RP-HPLC method for the determination of swertiamarin, sweroside, gentiopicrin and oleanolic acid in different parts of Swertia pseudochinesis.

METHODA Zorbax SB-C18 (4.6 mm x 250 mm, 5 microm) column was used with acetonitrile-water (10:90) and methnol-water(86:14) at detection wavelengths of 238 nm, 246 nm, 274 nm and 207 nm for swertiamarin, sweroside, gentiopicrin and oleanolic acid respectively. The flow rate was 1.0 mL x min(-1) and the column temperature was 25 degrees C.

RESULTAll of the compounds were based--isolated. The linear ranges of swertiamarin, sweroside, gentiopicrin and oleanolic acid were 0.068 9-0.344 4(r = 0.999 2) , 0.001 1-0.014 0 (r2 = 0. 999 8), 0.001 1-0.013 4 (r2 = 0.999 9) and 0.001 1-0.008 8 mg x mL(-1) (r2 = 0. 999 6), respectively.

After the epidemic of novel Coronavirus Disease 2019(COVID-19), construction of disease prevention and control has become a top priority. As a pioneer in the recovery of global economy and society, Shanghai should play a fundamental role in building a comprehensive system of public health and advanced disease prevention and control in the new era. In this article, we systematically categorize the requirements for the construction of disease prevention and control system in the new era, identify the weakness and challenges during and after the epidemic, and then make suggestions. It is proposed that we should utilize the important window period of the"14th Five-Year Plan", with the"Healthy China"strategy and municipal"20 Tasks for Public Health Construction"as the starting point, to make substantial contribution to the functional orientation, investment of resources, capacity building, operational mechanism and team building, which may provide scientific evidence for the reform and development of disease prevention and control system.

Objective To investigate the clinical efficacy of kinetic rectification acupuncture in treating acute facial neuritis. Method Sixty patients with acute facial neuritis were randomized to observation and control groups. The observation group received kinetic rectification acupuncture and the control group, conventional acupuncture alone. Acupuncture was given five times a week, five times as one course. The therapeutic effects were evaluated after three courses of treatment. Result The total efficacy rate was 93.3% in the observation group and 73.3% in the control group; there was a statistically significant difference between the two groups (P<0.05). The latencies and amplitudes of the frontal muscle, orbicularis oculi muscle and quadrate muscle of upper lip improved in the two groups after treatment and had statistically significant pre-/post-treatment differences (P < 0.01). There were statistically significant differences in the pre-/post-treatment difference values of the latencies and amplitudes of the frontal muscle and orbicularis oculi muscle (P<0.01) and no statistically significant difference in the pre-/post-treatment difference values of the latency and amplitude of the quadrate muscle of upper lip (P>0.05) between the two groups. Conclusion Kinetic rectification acupuncture has a marked therapeutic effect on acute facial neuritis. This study provides a particular therapeutic method for clinical practice.

Tumor necrosis factor (TNF) is a key cytokine in immunology system and is related to many human diseases. In order to inhibit the activity of TNF, cDNA coding for soluble TNF receptor II (sTNFRII) and human IgG Fc were linked using a flexible hinge. This gene was expressed in E. coli as a chimeric protein and purified by metal chelate chromatography. The results show that the fusion protein exists in the physiological form as a dimer, has the ability to bind with TNF and inhibits the cytotoxicity of TNF on L929 cells. Contrasting to monomer sTNFRII, the chimeric protein has an improved bioactivity, and displays potential prospects for research and application.

OBJECTIVETo determine the therapeutic effectiveness and safety of polyethylene glycol 4000 (forlax) in the treatment of constipation in children over 8 years old.

METHODSThis study was designed as a randomized, positive medicine (lactulose) controlled multicenter trial. A total of 216 children with constipation from 8-18 years old from 7 hospitals across China who were matched with a uniform entry criteria were enrolled in this study. The 216 patients were randomized to receive either oral forlax (20 g/d, n=105) or lactulose (15 mL/d, n=111) for 2 weeks. The therapeutic effects, including bowel movement frequency, stool consistency, clinical complete remission rate of constipation and abdominal symptoms, and the safety of forlax and lactulose were evaluated at 1 and 2 weeks of treatment.

RESULTSThe median weekly frequency of bowel movement in the forlax group increased by 4 and 5 times respectively after 1 and 2 weeks of treatment, and increased by 3 and 4 times in the lactulose group (P < 0.05). The stool consistency of the two groups was both improved significantly after treatment. The Bristol score of stool consistency of the forlax and lactulose groups were 3.41+/-1.11 and 3.64+/-1.33 respectively (P < 0.05) after 1 week of treatment, and were 4.26+/-0.89 and 3.63+/-1.33 respectively (P < 0.05) after 2 weeks of treatment. The clinical complete remission rate of constipation in the forlax and lactulose groups was 70% and 40% respectively (P < 0.05) by week 1 of treatment, and that was 72% and 41% respectively (P < 0.05) by week 2 of treatment. Abdominal pain disappeared in 75% of patients in the forlax group but in only 57% in the lactulose group by week 2 of treatment (P < 0.05). No serious adverse events happened and no abnormalities were found in laboratory tests and physical examinations in the two groups after medication.

CONCLUSIONSForlax is safe and effective in the treatment of constipation in children over 8 years old.

OBJECTIVETo study comparatively the characteristics of absorption and distribution of mercury and arsenic from realgar and cinnabar of Angong Niuhuang Pill in normal rats and the rats with cerebral ischemia after oral administration.

METHODThe blood samples and homogenates of liver, kidney and brain were prepared at various intervals after the animals were treated with Angong Niuhuang pill ig. The levels of total mercury and total arsenic in the blood and the organ homogenates were measured with Microwava Accelerated Reaction System and AAs, respectively.

RESULTThe blood concentrations of mercury and arseic reached the highest point in normal rats at one hour following single oral dosing of Angong Niuhuang pill. In normal rats, the mercury distribution was characterized by its higher level in blood and kidneys than in other organs, while a higher distribution of arsenic was found in blood than in organs. No difference in the distribution of mercury or arsenic was found between normal rats and rats with cerebral ischemia after the treatment with the pill.

CONCLUSIONThe highest level of mercury or arsenic in blood occurs at one hour after oral administration of the pill in normal rats. There is a higher distribution of mercury in blood and kidneys, while a higher distribution of the arsenic only in blood. There is no significant difference in the distribution of mercury or arsenic between the normal rats and the ischemic rats.

OBJECTIVEBased on the therapeutic claims of Angong Niuhuang pill, a series of pharmacodynamic experiments were designed, where pharmacological effects were investigated comparatively with its simplified prescription(realgar and cinnabar are removed from the original pill) as a parallel control in order to explore possible contribution of cinnabar and realgar to pharmacodynamic activities of the pill as a whole.

METHODAnti-pyretic, sedative, anti-convulsive, and mice-protected effects of the pill and its simplified prescription as a control were observed, respectively, in rabbits with fever induced by typhoid bacillus, in pentobarbital sodium-induced sleeping mice, in mice with convulsion induced by strychnine, or pentylenetetrazole, and in mice with anoxia induced by NaNO2.

RESULTBoth the pill and its simplified prescription were found to have Anti-pyretic action and protective effect against the mouse death induced by anoxia, and synergistic interaction with pentobarbital sodium in sedative activity, although neither of them was found to have any effects on the convulsion of mice.

CONCLUSIONNo significant difference between Angong Niuhuang pill and its simplified prescription was found in the above pharmacodynamic experiments.
