1.Azathioprine Treatment in Systemic Lupus Erythematosus: A Double Edged Sword
The International Medical Journal Malaysia 2015;14(2):61-62
Extremely severe pancytopenia induced by low dosage of azathioprine in systemic lupus erythematosus patients
is rare. A 40-year-old Chinese female was diagnosed with systemic lupus erythematosus. She suffered worse
erythema, oral ulceration, raised erythrocyte sedimentation rate and high anti-dsDNA in August 2013. Then she
was initiated on oral azathioprine 50mg/d and extremely severe pancytopenia was seen in September 2013. She
was recovered by a series of treatments. Regular monitoring of blood counts is highly recommended to reduce
the possible serious myelosuppression induced by azathioprine.

Objective To optimize the extracting conditions of Anchuan Keli. Method Six crude drugs, including Ephedra herb and so on, with the ephedrina hydrochloridum content as the index, extracting times, water volume and extracting time were screened by orthogonal test. Two crude drugs, including Sophora flavescens and so on, with matrine and ammothamnine content as the indexes, alcohol concentration, extracting times, alcohol volume and extracting time were screened by orthogonal test. Result The optimal extracting condition of six crude drugs including Ephedra herb was heat reflux and extracting 2 times (the first time 854 mL, the second time 732 mL), 2 hours for each time using water. The optimal extracting condition of two crude drugs include Sophora flavescens was heat reflux and extracting 2 times (the first time 288 mL, the second time 240 mL), 2 hours for each time using 80% alcohol. Conclusion The extracting technology selected is reasonable, practical and controllable.

BACKGROUND:Electromagnetic fields can cause changes of the body,especially the nervous system.Effect of pulsed electromagnetic fields(PEMFs)on neural stem cells has been detected.OBJECTIVE:To investigate the effect of prenatal pulsed electromagnetic fields(PPEMFs)on neural stem cell proliferation and nestin protein expression in the hippocampus of rat offspdng.METHODS:Sprague Dawley female rats weighing 240-260 g were included and randomly divided into two groups:control and PPEMFs.Rats from the control group were given no interventions.Rats from the PPEMFs group were given PEMFs stress at gestational days 14-20.Each stress was given three times daily for 10 minutes.The male and female offspring rats were sacrificed at 1 month of age and their brains were sectioned to determine the expression of nestin protein and Brdu-positive cells in the hippocampus by immunohistochemistry.RESULTS:The expression of nestin-and Brdu-positive cells in the hippocampus of female and male PEMFS offspring were significantly higher compared with the control group(P<0.001),and there was a significant difference between female and male offspring(P<0.001).The nestin-and Brdu-positive cells in female offspring outnumbered those in male offspring(P<0.001);however,there was no significant difference between female and male offspring in the control group(P>0.05).CONCLUSION:PPEMFs can increase the number and proliferative capability of the neural stem cells in offspring.It may be a pdmary stage of the cascade reaction of the body to the brain damage caused by PPEMFs stress.

OBJECTIVETo dynamically assess drug targeting of Yougui Pill (YP) and Zuogui Pill (ZP) using infrared thermography.
METHODSIn this self-control experiment, five healthy volunteers were recruited. By using infrared thermography 10 to 11 thermal images of different body locations were taken from each participant after they took warm water, YP, ZP, and their dissembled prescriptions at 30, 70, 100, 130, and 160 min, respectively. The heat values in the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) were statistically analyzed after scanning for 125 times.
RESULTSAdministration of YP and its disassembled prescriptions enhanced the heat value of the locations of the Du channel and Shenque (CV8), but did no enhance the heat value of the lower quadrant abdomen at 30 min. Administration of ZP and its disassembled prescriptions reduced the heat value in the locations of the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) at each time point.
CONCLUSIONThe drug targeting of ZP and YP focused on the locations of the Du channel and Shenque (CV8), not on the locations of the lower quadrant abdomen or uterus.

Objective To investigate principles of acupoint selection for the ancient acupuncture and moxibustion treatment of facial paralysis.Methods The ancient literature about acupuncture and moxibustion was collected and reviewed from the pre-Qin period to the late Qing Dynasty. According to the data selection criteria, acupuncture and moxibustion prescriptions of facial paralysis were collected and input into an ancient acupuncture and moxibustion prescription database. By use of frequency analysis and factor analysis, the principles of acupoint selection were obtained.ResultsTotally 257 prescriptions were collected which involve 74 acupoints. Through frequency analysis, 19 acupoints were obtained whose frequencies were equal or greater than 9, such as Dicang (ST 4), Jiache (ST 6), Tinghui (GB 2), Shuigou (GV 26), Hegu (LI 4), etc. Through factor analysis of acupoint variables, 6 common factors were obtained.Conclusion Based on analysis of the common factors, the principles of acupoint selection are summarized which were according to meridian, part and etiology for the ancient acupuncture treatment of facial paralysis. The results could provide a reference for clinical acupuncture and moxibustion treatment. It is feasible that factor analysis was applied to study principles of acupoint selection for acupuncture and moxibustion prescriptions.

Objective To analyze the clinical features of systemic lupus erythematosus (SLE) com-plicated by noncirrhotic portal hypertention (NCPH),and improve the recognition of NCPH.Methods Clinical data from SLE complicated by NCPH in our hospital were retrospectively analyzed and summarized,while the related literatures were reviewed.Results Four patients diagnosed as SLE complicated by NCPH were all women.NCPH presented with the clinical features of portal hypertension with normal or slightly elevated transaminase.Anticardiolipin (ACL) antibodies were positive in 2 patients.Two patients underwent liver needle biopsy,showing nodular regenerative hyperplasia,of which,one with liver portal fibrosis.The treatment strategy was managing the primary disorder and controling of portal hypertention in four patients.Twenty-two cases of SLE complicated by NCPH were reviewed and analyzed,including 18 cases from related literatures and our 4 cases.Among the 22 cases,the mean time between the diagnosis of SLE and NCPH was eight years,of which one patient with NCPH before SLE,one diagnosed at the same time and the rest with NCPH after SLE.19% (4/21) of patients presented with Raynaud's phenomenon and 18% (4/22) complicated by pulmonary hypertension.In serological tests,patients presented with positive ACL anti-bodies [33%(7/21)] and anti-dsDNA [48%(10/21)],as well as increased IgG and γ-Globulin [38%(8/21)].Liver needle biopsy showed nodular regenerative hyperplasia or liver portal fibrosis with the prevalence of 80% (16/20) and 25% (5/20),respectively.Conclusion SLE complicated by NCPH is very rare clinically and is easily being misdiagnosed without obvious symptoms and signs in the early stage.Positive ACL antibodies and Raynaud's phenomenon maybe be closely related to SLE complicated by NCPH.

OBJECTIVE: To optimize the extraction process of Fructus Schisandrae Chinensis. METHODS: Taking the contents of schizandrin, schisantherin A, deoxyschizandrin, r-schizandrin as the indexes, the influence on the extraction process by extract solvent and medicinal material particle diameter was examined, and the extraction parameters were optimized. RESULTS: Active components of Fructus Schisandrae Chinensis, after the medicinal material being crushed, can be effectively utilized through extracting by alcohol. The optimized extraction parameters were as follows: the medical material being ground into 40 meshes, extracted twice by 70% alcohol, 2 hours per time. CONCLUSION: The optimized extracting process works better than current technique adopted for formulated granule preparation, and can ensure quality to the highest degree.
