A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

OBJECTIVETo investigate the immunological activity of Streptomyces polysaccharide (SMP) on normal and immunosuppressed mice.

METHODSThe effect of SMP on the proliferating activity of normal mouse splenocytes was tested in the mixed lymphocyte culture, and the changes of peripheral blood T lymphocytes were evaluated with acid a-naphthyl acetate esterase (ANAE) method. The ratio of Lyt2+ and L3T4+ T cell subsets was measured by flow cytometry.

RESULTSSMP stimulated obvious proliferation of mixed lymphocytes, showed protective effects on T lymphocyte and increased the ratio of Lyt2+ and L3T4+ cell subsets to nearly normal level in immunosuppressed mice.

CONCLUSIONSSMP can regulate the immune function in mice.

Objective To observe the clinical effect of Yiqi Yangyin Huoxue decoction(the function of decoction is to tonify Qi,nourish Yin and enhance blood circulation)on salivary gland response attribute to radiotherapy.Methods This study,carried between January 2005 and December 2005,focused on the effect of Chinese herbs on salivary gland response attribute to radiotherapy.In the treatment group,30 cases took Chinese herbs during the duration of radiotherapy,while in the control group 30 cases were given routine therapy.Results Both groups had finished the radiotherapy,however,in the control group,there were 5 cas- es with a break for 1～2 weeks.For the comparison of the salivary gland change in acute stage,there was no variance(x~2=2.387,P=0.122);the latency for the salivary gland change in treatment group was longer than that in control group(x~2=13.106,P=0.000).For the comparison of Karnofsky after radiotherapy,the KS was superior in the treatment group than that in control group(x~2=12.685,P=0.013);For the comparison of objective effect after radiotherapy,the remission rate in treatment group was 90 %,and it was 86.7 % in control group(x~2=0.638,P=0.727).Conclusion The decoction can remit the salivary gland response caused by radiotherapy in clinic,prolong the latency for acute radioactive response;release the pain of the pa- tients,increase the achievement ratio for radiotherapy,and improve the patients'living condition.To combine with radiotherapy,Chinese herbs is a good supplemental therapy for nasopharyngeal carcinoma

ObjectiveTo investigate the effect of simvastatin on severe complications and prognosis of subarachnoid heamorrhage (SAH).Methods98 cases with SAH were randomly divided into the treatment groups and control group (finally, there were 32 cases in treatment group, 48 cases in control group). Patients in treatment group were given simvastatin 20 mg/day, and those in control group were treated with routine therapy. The incidences of cerebral vasospasm, hydrocephalus, rebleeding and mortality between the two groups were compared.ResultsThe incidence of hydrocephalus of treatment group was 3.13%; that of control group was 18.7%, there was a significantly difference between two groups (P<0.05). There were no significant differences for incidences of cerebral vasospasm, rebleeding and mortality between two groups (P>0.05).ConclusionSimvastatin can reduce the occurrence of hydrocephalus after SAH.

Background Researches showed that multifocal electroretinogram (mfERG) is able to assess the retinal function in the eyes with acute Vogt-Koyanagi-Harada ( VKH ) syndrome. But the mfERG characteristics of convalescence stage of VKH are still below clear. Objective Present study was to compare and follow up the variation process of visual acuity and mfERG in acute and recovery stages of VKH syndrome. Methods This was a clinic-based retrospective study. Visual acuity, mfERG and fundus fluorescence angiography ( FFA ) were recorded from 35 eyes of 18 acute VKH cases. The period of follow-up in recovery stage lasted about 18 months with the repetitive recording results for 4 times. Results In this study, the visual acuity range in acute stage VKH was 0. 01 to 1.0, and 91.4% (32/35 eyes) was below 0.6. Compared with normal control group, the visual acuity was significantly decreased (P＜0.01). The response densities (amplitudes) of N1 ,P1 waves of the first-order kernel were significantly lowed in all the 6 rings,and the implicit times of 1-4 rings of both waves were significantly prolonged in acute VKH eyes(P＜0. 05). The abnormalities of retinal function showed a regional difference at the posterior pole retina with the dominant change in the first ring,showing a cutting off78% in the P1 amplitude. The abnormal degree of mfERG was more serious as the the increase of retinal eccentricity. In 2 months of convalescence after glucocorticosteroids therapy,the range of visual acuity were 0. 1-1.2 ,and the amplitudes of N1, P1 of 1-2 rings were greatly elevated in comparison with acute on-set (P＜0. 05 ). However, there was still a remarkable difference in the amplitudes of from 1 through 6 rings,comparing with normal. The response density of P1 wave from whole recording region was only 44% of normal. Though the visual acuity was stable during the follow-up duration, a decreasing tendency in N1 and P1 amplitudes were seen. The implicit times of both wave shortened only in 1-3 rings in recovery stages of VKH (P＜0.05). Conclusion VKH syndrome cause serious damage of posterior retinal function.Macular region is the site with greater retinal functional lesion and restore before and after medication. This hardly recovery of retinal function can last over one and half year,even satisfied visual acuity is stable after proper treatment.

In order to study the spectral reflectance differences of Glycyrrhizae Radix under different growth conditions and lay the foundation for quantitative monitoring of Glycyrrhizae Radix remote sensing images, spectra of Glycyrrhiza species under different growth period and different varieties and different regions were measured by a portable spectrometer. The results showed that the reflectivity of annual G. uralensis was obviously higher than that of the two years plant in the visible light band own to the contents of crown layer chlorophyll. The reflectivity of two years G. pallidiflora was higher than that of G. uralensis in the near infrared band own to the leaf area index and the content of leaf water. The red edge spectrum of annual plant fluctuated largely than that of two years plant due to vegetation coverage and leaf area index. G. pallidiflora grew well than G. uralensis. Under different regions of the Glycyrrhiza species, spectral data analysis showed that within a certain range, the average annual precipitation and average annual evaporation were the major factors to affect the differences of Glycyrrhiza species spectral data under different regions owe to the leaf water content, the higher leaf water content, the lower spectral reflectance. The principal component analysis and continuum-removed method of the spectral data under different regions found that, within a certain range, the average annual precipitation and average annual evaporation were the major factors caused by the differences of Glycyrrhiza species spectral data under the different regions, Glycyrrhiza species spectral similarity related to the spatial distance.

Chinese patent orthopedic medicines feature complex components, mainly including desperate and toxic herbal pieces, narrow safety window, more clinical contraindications and frequent adverse drug reaction/events (ADR/ADE). To study the general safe medication regularity of Chinese patent orthopedic medicines, define key points in the medication education and ensure rational clinical medication, the authors took 80 types of commonly used Chinese patent orthopedic medicines as the study objects, collect 237 cases from 164 ADR/ADE documents through a system retrieval strategy, make a multidimensional literature analysis to determine the common risk factors for safe and rational medication of Chinese patent orthopedic medicines and establish an ADR/ADE prevention regularity. First, in the aspect of clinical symptoms, skin allergy is the most common ADR/ADE and closely related to the toxic ingredients, particularly accumulated liver or kidney damage caused by some drugs. Second, there are three time nodes in the ADR/ADE occurrence; The ADR/ADE occurred in 30 minutes is closely related to the idiosyncrasy; the ADR/ADE occurred between several months and half a year is related to the drug-induced liver and kidney damages; The most common ADR/ADE was observed within 7 days and predictable according to the pharmacological actions; Third, toxicity is an important factor in the occurrence of ADR/ADE of Chinese patent orthopedic medicines. Fourth, emphasis shall be given to the special medication factors, such as the combination with western medicines and Chinese herbal decoctions, overdose and long-course medication and self-medical therapy. In conclusion, the general ADR/ADE prevention regularity for Chinese patent orthopedic medicines was summarized to provide supports for clinicians in safe and rational medication and give the guidance for pharmacist in medication education.
