Objective To investigate the clinical efficacy and summarize the experience of treating patients with hepatic injuries in a primary-care hospital.Methods The clinical data of 230 patients with hepatic injuries from January 2002 to December 2014 were retrospectively analyzed.Results 124 patients were treated with surgery and 106 patients (including two patients who were transferred to another hospital) were managed by conservative treatment.Of 230 patients,204 patients recovered well and 26 patients died.63 cases of severe hepatic injuries (grades Ⅲ,Ⅳ,Ⅴ and Ⅵ),the mortality rate reached 25.4％.Concltsions The important points to success in managing these patients are early diagnosis and adequate assessment of liver injury,proper choice of treatment and using the simplest and the most effective means in surgery to control bleeding.

Objective To investigate the effects of empathy on the insight of first-episode schizophrenia.Methods Empathy with tbe interpersonal reactivity index-C (IRI-C) was applied to 71 patients with first-episode schizophrenia and 69 healthy controls.In addition,schizophrenic patients were evaluated with scale of unawareness of mental disorder (SUMD) for the scores of clinical insight and positive and negative syndrome scale (PANSS) for clinical symptoms.Results Compared with the control group,the schizophrenic patients showed lower scores in the perspective taking ((13.85±1.86) vs (6.74±2.56),P＜0.01),empathic concern ((14.28±2.16) vs (17.49± 2.73),P＜0.01) of IRI-C,but higher subscale score ((10.28±2.78) vs (8.93±1.93),P＜0.01) in personal distress.Pearson correlation analysis showed that,there were negatively significant correlations between insight score and perspective taking (r=-0.429,P＜0.01),empathic concern (r=-0.709,P＜0.01) subscores of IRI-C respectively.In addition,the insight total score was positively correlated with the positive symptoms subscores (r=0.545,P＜0.01) of PANSS.Conclusion Patients with first-episode schizophrenia have significant empathy defects.And the empathic deficits are associated with the insight impairment among the schizophrenic patients,suggesting that patients' insight level can change by improving their empathy ability.

Objective To investigate the clinical effects of standard large trauma craniectomy in patients with acute posttraumatic brain swelling. Methods A cohort study was performed in 74 patients of acute posttraumatic brain swelling with midline shifting more than 5 mm, who were divided randomly into two groups: standard large trauma craniectomy group (n =37) and routine temporoparietal craniectomy group as control group (n =37). The vital sign, the intracranial pressure (ICP) and complications were observed during the treatment. The Glasgow outcome scale (GOS) and mortality rate as well as the complications were evaluated after treatment. Results The mean ICP in the large trauma craniectomy group at 24, 48, 72 and 96 hours was much lower than those of the control group ( P

Objectiye To observe the prevalence of prolonged seizures and the changes of biochemical markers of myocardial injury in patients with prolonged seizures after modified electroconvulsive therapy(MECT).Methods Patients treated with MECT or simulated ECT were divided into three groups.Group Ⅰ , 26 patients,experienced at least one prolonged seizure after MECT;group Ⅱ,41 selected patients, had not prolonged seizures at all during a course of MECT treatments and group Ⅲ, 31 patients, received simulated ECT.Biochemical markers of myocardial injury, including phosphocreatine kinase (CK), MR isoenzyme of phosphocreatine kinase (CK-MB), lactate dehydrogenase ( LDH ), α-hydroxybutyrate dehydrogenase ( α-HBDH ) and cardiac troponin (cTnT) ,were measured immediately, 3 hours later and on the following day after the first prolonged seizure for group Ⅰ ,the same time points as group Ⅰ after the first treatment of MECT for group Ⅱ , immediately after simulated ECT for group Ⅲ.These indexes were compared between the patients of three groups.Results The positive rate ofcTnT was 30.8%(8/26) and 17.1% (7/41)in group Ⅰ and Ⅱ respectively, but no difference was found(P＞0.05 ).CK measured immediately after MECT in patients of group Ⅰ was significantly higher than that of group Ⅲ(P ＜ 0.05 ).CK-MB (immediately), LDH ( immediately and 3 hours later) and α-HBDH ( immediately, 3 hours later and on the following day) in patients of group Ⅰ were significantly higher than those of group Ⅱ and Ⅲ measured after MECT or simulated ECT(P＜0.05 ).Conclusion More attention should be paid that absolute or relative hypoxemia may lead to minor myocardial injury.

Groups of mice were administered intragastrically either with primaquine alone or in combination with pyronaridine. The number of mice died in groups treated by pyronaridine 293-507 mg/kg combined with primaquine 50 mg/kg were not more than those in group by primaquine alone, but significantly less than those in groups by combination of chloroquine 102-253 mg/kg and primaquine. The tests of primary tissue schizontocidal activity in rhesus monkeys inoculated, with Pladmodium cynomolgi sporozoitcs showed that all monkeys were cured either by treatment of ig primaquine alone, 3 mg/kg/d ? 3, or by a single im dose of pyronaridine 10 mg/kg combined with primaquine starting on the day of infection. No influence of pyronaridine on primaquine was observed in P. yoelii sporozoites-infected mice.

Aim To explore the change of mGluR1α and mGluR5 expression in brain CA1 region after infrasonic action, and the role of antagonist MCPG in rats. Methods 160 SD rats were divided randomly into infrasonic damage group and MCPG therapy group. The two groups were subdivided into control group and 1-time, 7-time and 14-time groups respectively. Rats were exposed to 8Hz, 130dB infrasound two hours each time. Expression of mGluR1α and mGluR5 were detected by immunohistochemical staining and in situ hybridization methods. The morphological changes of neurons after MCPG therapy were observed under microscopes. Results Comparing with the control group, the number and the A value of mGluR1α and mGluR5 positive cells changed after one infrasonic action(P∨ 0.05); and the expression of mGluR1α and mGluR5 in the 7-time group were most obvious(P∨ 0.01); in the 14-time group, they recovered already to normal level. Morphological study confirmed that MCPG protected neurons from infrasonic damage. Conclusion Change of mGluR1α and mGluR5 activity can mediate exciting neurotoxicity after infrasonic action, and it is one of the major factors relative to neurons injury, MCPG had an protective effect on brain damage caused by infrasound.

A new method was established for the direct, rapid and quantitative analysis of pesticide residues, dimethoate chlorothalonil and malathion by low temperature plasma ( LTP) ionization miniature ion trap mass spectrometer. The LTP ionization probe and sample inlet of ion trap mass spectrometry were enclosed in a metal cavity. With non-contact heating, the samples placed on the sample platform were desorbed into gaseous phase and ionized by LTP ionization probe. The results showed that closed ionization had an edge over the opened ionization. The quantitative analysis of 3 pesticides within the range of 0. 5-10 mg/L was realized by optimizing heating time and flow rate of air, and the relative standard deviations of signal intensity is less than 11%. LODs of pesticide, which were obtained within 5 s, were as low as several hundred pictograms. The results showed that the method could be used for the analysis of pesticide residue on green and organic fruits or vegetables.

Reduced sulfur compounds ( RSCs) are one of the main pollutant species in the atmosphere, so it is of great significance to develop a rapid and on-line approaches for their detection. In this study, a portable time-of-flight mass spectrometer ( TOF-MS) with magnetic field enhanced photoelectron ionization source was designed to detect RSCs. The photoelectron ionization source was induced from vacuum ultraviolet photons which generated from vacuum ultraviolet (VUV) lamp with energy of 10. 6 eV. The energy of photoelectrons was controlled by adjusting the extraction voltage to produce the photoelectron ionization, and an annular magnet was used in the ionization region to improve the ionization efficiency of photoelectrons. From the simulation result by SIMION software, it was found that the introduction of magnet field made the motion trajectroies of electrons in the helical motion increase and the convergence of electron at the ionization source was achieved. Experimental results showed that after introducing the magnet filed, the sensitivity of H2 S, SO2 and CS2 was improved by a factor of 5. 3, 9. 4 and 6. 9, respectively. With a detection time of 50 s, the limits of detection for H2S, SO2 and CS2 were 0. 14, 0. 52 and 0. 31 mg/m3(S/N=3), respectively. It could be concluded that the portable TOF-MS with magnetic field enhanced photoelectron ionization source has great potential to be applied for on-line monitoring of volatile sulfides at the emission source.

Electroconvulsive therapy (ECT) is not currently used as a first-line treatment for obsessive-compulsive disorder (OCD). However, several related case reports have demonstrated that ECT seems to be effective for severe OCD, especially when first-line therapies have failed. In this study, we describe the courses, detailed parameters, effects, and follow-up information relating to three patients with severe OCD who were treated by modified bifrontal ECT after their first-line anti-OCD treatments pharmacotherapy, behavioral therapy, and cognitive behavioral therapy failed. The number of ECT procedures administered in each case is as follows: Case 1, eight; Case 2, three; and Case 3, four. In all three cases, the patients' depressive symptoms improved considerably after the ECT procedures. In addition, the condition of all three patients' OCD significantly improved and remained stable at regular follow-ups. ECT may play an effective role in treating severe OCD.
