Objective To investigate the effect of modified electroconvulsive therapy (MECT) with different anesthetics on efficacy of patients with treatment-resistant depression (TRD). Methods Ninety patients with TRD were enrolled in this study to receive a standard 8 times MECT. The HAMD-17 scale was evaluated before MECT and after the completion of the first, second, third, forth, sixth and eighth MECT session. The TESS scale was evaluated before MECT and after the completion of the last MECT session. Results Scores of HAMD-17 after the completion of the first, second, third, fourth, sixth and eighth MECT session were significantly reduced (P<0.05). There were significant differences of HAMD scales among the three groups since the first MECT session (P < 0.05). The remission rate of ketamine group, propofol group and mixed group was 96.7%, 43.3%, and 73.3% (P < 0.05). Conclusion MECT of ketamine anesthetic might contribute to the best effect of TRD.

Objective To evaluate the diagnostic value of the aldosterone-renin ratio (ARR) for primary aldosteronism (PA). Methods Serum aldosteronos ( ALD ) and plasma renin activities (PRA)among 44 subjects with primary aldosteronism, 9 subjects with phecchromocytoma, 8 subjects with nonfunctional adrenal tumors, 12 subjects with Cushing syndrome, 4 subjects with stenosis of renal artery and 13 subjects with primary hypertension were retrospectively reviewed. ARR was calculated. The receiver operating characteristics (ROC) curves for every index were used to evaluate diagnostic value. Results The area under the curve(AUC) in the ROC curve of ALD in a supine position was 0. 947, the cut-off value of diagnosis of PA. The AUC for the ROC curve of ALD in upright position was 0. 889, the cut-off value of ALD diagnosis of PA. The AUC for the ROC curve of ARR in a supine position was 0. 978, the cut-off value of diagnosis of PA. The AUC for the ROC curve of ARR in upright position was 0. 981, the cut-off value of specificity. If ARR was combined with ALD in upright position was used, the diagnostic value was better than either index. When ALD > 275 ng/L and the AUC for the ROC curve in upright position was 0. 989,specificity. Conclusions The diagnostic value of ARR in diagnosis of primary aldosteronism is higher than ALD and PRA. ARR in upright position is better than that in supine position, especially when combined with ALD > 275 ng/L in upright position.

Objective To study the changes of plasma gastrin (Gas), substance P (SP) and vascoactive intestinal peptide (VIP) among children with recurrent abdominal pain and their family members,and to explore if there is the rule of the changes.Methods The fasting plasma Gas, SP and VIP were determined by radioimmunoassay method among 30 children with recurrent abdominal pain, and 45 family members including first-degree relatives and second-degree relatives as well as 35 normal healthy children and 20 normal healthy adults. Individuals were divided into five groups:children with recurrent abdominal pain (study group 1), family members with recurrent abdominal pain (study group 2), normal healthy children (control group1), family adults without recurrent abdominal pain (control group2) and normal healthy adults (control group3) . The whole family members of 7 children with recurrent abdominal pain were focused on and analysed.Results 55 of 130 volunteers were with recurrent abdominal pain including 30 children and 25 adults. There were 22 adults with and 20 adults without recurrent abdominal pain in the whole family members of 7 children with recurrent abdominal pain. The fasting plasma Gas content had no difference between study group 1 and control group1 ( <0.05), but the levels of fasting plasma SP and VIP were both in decrease and had difference between study group 1 and control group1 (<0.05) .The fasting plasma Gas,SP and VIP had no difference between study group 2 and control group 2 ( >0.05) .The levels of fasting plasma Gas content had no difference between study group 2 and control group 3 (>0.05),but the levels of fasting plasma SP and VIP were both in increase and had difference between study group 2 and control group3. The fasting plasma Gas content had no difference between country group 1 and control group3 ( <0.05),but the levels of fasting plasma SP and VIP had difference between country group 1 and control group3 ( <0.01) .The levels of fasting plasma SP and VIP had no difference between study group 1 and study group 2 ( <0.05) .The levels of fasting plasma Gas, SP and VIP content had no difference among the whole family members of 7 children with recurrent abdominal pain including 22 adult members with and 20 adult members without recurrent abdominal pain (>0.05) .Conclusions There are the same plasma Gas contents in normal children and adults.However, the plasma SP and VIP contents are higher in normal children than ones in normal adults. The plasma SP and VIP contents are lower in children with recurrent abdominal pain than ones in normal children. The plasma SP and VIP contents are higher in adults with recurrent abdominal pain than ones in normal adults. These suggested that the increases of plasma SP and VIP may have a close relationship with the pathogenesis of children and adults with recurrent abdominal pain. The contents of plasma Gas, SP and VIP were consistent in the whole family members of 7 children with recurrent abdominal pain. It suggested that the secretion of gastrointestinal hormone is disorder in the families with recurrent abdominal pain.

Cordyceps sinensis is an expensive and tonic-valuable famous herb in China. Due to a narrow growing distribution, a low parasitic rate and a harsh living environmental condition, its wild recourse is not abundant. In re-cent years, with the improvement of living standards, people’s awareness of health care has increased strongly. That is because of people’s over-excavation need;and the natural resources are becoming increasing scarcity. In order to meet the demand for Cordyceps, domestic researchers conducted vigorous studies. Since 1987, four or five cul-tured Cordyceps species have been developed, namely fermented Cordyceps sinensis. Through subsequent unceasing research, they were put into a lot of production, bringing a certain benefits for income and society. Currently, there are four commercial brands on the market. They are Bailing, Jinshuibao, Xinganbao and Ningxinbao. This paper summarized the studies of its chemical compositions and clinical applications on fermented Cordyceps militaris in the recent five years. It will let scholars understand its value of the cultured Cordyceps militaris more comprehen-sively and supply more information for scholars in its further research.

The biochemical mechanism of degrading keratins by S.fradiae var S-221 was primarily studied.The compounds (Na_ 2 SO_ 4 , Na_ 2 SO_ 3 and sulfdryl acohol), which respecitively enhance specific activity of keratinase, activate keratinase intensively and mainly act on the disulfide bonds reductase in the keratinase, Na_ 2 SO_ 3 activates intensively both disulfide bonds reductase and polypeptide hydrolytase at 0.01 mol/L, whereas Na_ 2 S_ 2 O_ 3 , which acts on the disulfide bonds reductase, inhibits keratinase.On the condition that substrate, keratins exists, S.fradiae var S-221 is induced to produce exo-keratinase, which is a multiproteinase, containing disulfide bonds reductase, which is a key enzyme degrading keratins, then, with polypeptidic, hydrolytase, graduately hydrolyzates denatured keratins into polypeptides, oligopeptides and free amino acids, so that keratins have been decomposed completely.Sulfur in the keratins was transferred into sulfhydryl compounds, H_ 2 S and sulfates in the course of keratinolysine.

Objective:To study the changes of Th17,regulatory T(Treg) cells and IL-17,IL-23 levels at acute phase and recovery phase in children with Henoch-Schonlein purpura(HSP) in order to further understand the immunological pathogenesis and provide help for treating HSP. Methods:The vein blood samples were collected from 65 children with HSP and 30 normal children. The proportion of Th17 cells and regulatory T cells were tested by FCM and concentration of IL-17 and IL-23 in plasma were tested by ELISA. Results:Compared with normal children,the levels of Th17,Th17/Treg and IL-17,IL-23 were in increase at acute phase in children with HSP(P<0. 05). At recovery phase,that were in decrease compared with the acute phase(P<0. 05),but still higher than the normal children(P<0. 05). Compared with normal children,the level of Treg was in decrease at acute phase in children with HSP (P<0. 01). At recovery phase,that was in increase compared with the acute phase(P<0. 01),but still lower than the normal children (P<0. 01). Among the simplex,abdominal and other type of children with HSP,the levels of Th17,Treg,Th17/Treg and IL-17,IL-23 were same( P>0. 05 ) . At acute phase in children with HSP, Th17 cells percentage had positively correlated with IL-17 levels ( r=0. 880,P<0. 01),IL-23 levels had positively correlated with Th17 cells percentage and IL-17 levels (r=0. 838 or 0. 877,P<0. 01). Conclusion:Th17,Treg,Th17/Treg,IL-17 and IL-23 are involved in the course of the immunological pathogenesis in children with HSP,but the levels of that have no significant difference among simplex,abdominal and other types,further researches need to be done.

Background Selective laser trabeculoplasty(SLT)has been widely accepted for the treatment of open-angle glaucoma.However,there are few reports about its application in treating angle-closure glaucoma so far.Objective This study was to clinically evaluate the safety and efficacy of selective laser trabeculoplasty for primary angle-closure glaucoma with opened anterior angle follow-up surgery.Methods A case-observational design was adopted in this study.A total of 33 eyes from 23 angle-closure glaucomatous patients with opened 180° angle were enrolled.All the patients understood this trial and written informed consent was obtained prior to the medical treatment.The average preoperative intraocular pressure(IOP)and number of medication were(23.07±4.01)mmHg and 1.52±0.66,respectively.A frequency doubled Q-switched Nd:YAG laser was used to irradiate the trabecular meshwork with 70-80 laser spots over 180°.The same preoperative anti-glaucoma drugs were topically administered during the follow-up period.Visual acuity,IOP,slit lamp examination,gonioscopy and the coefficient of outflow facility were regularly assessed and performed after laser surgery.Results The IOP values of the 33 eyes were(18.78±4.87)mmHg,(18.83±3.95)mmHg,(19.78±4.48)mmHg,(19.63±3.68)mmHg,(19.11±3.36)mmHg,and(21.17±3.14)mmHg 1 day,l week,and 1,3,6,9 months after operation,showing significant decline in comparison with preoperation(P＜0.01).The mean drug uses were 1.63±0.85,1.23±1.01,1.25±0.98,1.21±1.02,1.22±0.86,and 1.69±0.53 at the same time point after operation,respectively,and significant differences were found 1 week,1,3,6 months in postoperation in comparison with preoperation(P =0.020,0.026,0.020,0.031).Ciliary congestion and aqueous flare naturally disappeared 1 week after surgery.The coefficients of outflow facility were 0.11±0.09 and 0.23±0.15,respectively at pretreatment and 3 months after SLT with a statistically significant difference (P=0.002).Conclusions Selective laser trabeculoplasty is effective and safe for angle-closure glaucoma.However,it is essential to have 1/2 circle of anterior chamber open for SLT in angle-closure glaucoma.

This study was aimed to explore the effect of Periplaneta Americana against alcohol-induced liver injury in mice, in order to provide a theoretical basis for the industrial production of P. Americana. Kunming mice were randomly divided into six groups, which were the normal group, model group, positive group, high-, middle-, low-dose of P. Americana groups. Intragastric administration of Tiopronin Enteric-coated Tablets 100 mg·kg-1 was given to the positive group. Intragastric administrations of whole powder of medicine were given to the high-, middle-, low-dose groups with the dosage of 6.667, 3.333, 1.667 g·kg-1, respectively. The drugs were given daily for 10 con-secutive days. After 3h of the 10th day drug administration, intragastric administration of distilled water was given to the normal group, while 14mL·kg-1 of 56℃ Red Star Liquor was given to other groups. No food was given but water for 12h. Blood was collected from the orbit. The ALT, AST and GGT in blood serum of mice were measured. The liver was dissected and liver coefficient was calculated. Histopathological examination was given on liver tissues. The results showed that compared with the normal group, the level of ALT, AST in blood serum of the model group had obvious enhanced (P< 0.01), the level of GGT had obvious enhanced (P< 0.05). Compared with the model group, the level of GGT, AST of the high-, middle-dose group had obvious enhanced (P< 0.05), the level of ALT activity had obvious enhanced (P< 0.01). There were severe liver histopathological damages in mice of the high-, middle-, low-dose group. It was concluded that P. Americana had some side effects in the treatment of alcohol-induced liver injury.
