Chinese Traditional Patent Medicine 1992;0(02):-
AIM:To establish the quality standard for Guanxin Plaster(Radix et Rhizoma Salviae miltiorrhizae,Rhizoma Chuanxiong,Olibanum,etc). METHODS: Radix et Rhizoma Salviae miltiorrhizae;Rhizoma Chuanxiong and Radix Angeliae pubescentis of Guanxin Plaster were identified by TLC.Camphor,menthol and borneolum syntheticum were cletermined by GC together. RESULTS: The characteristic identification by TLC was distinct and highly specific.Camphor showed a good liner relationship at a range of 0.095 ?g-0.95 ?g,(r=0.999 7,n=5).Menthol showed a good linear relationship at a range of 0.123 ?g-1.23 ?g,r=0.999 6,n=5).Borneolum syntheticum showed a good liner relationship at a range of 0.202 ?g-2.02 ?g,(r=0.999 7,n=5).The average recoveries were 99.6%(RSD=1.9%) for camphor,98.4%(RSD=2.0%) for menthol,98.2%(RSD=3.8%) for bomeolum syntheticum. CONCLUSION: The method is reliable,accurate and specific.It can be used for quality control of Guanxin Plaster.

Objective To explore the influence of smoking on olfactory disorder in Parkinson's disease (PD). Methods According to smoking or not, 167 PD patients ( PD group) and 100 normal controls ( normal control group) were divided into smoking subgroups and non-smoking subgroups.The olfactory identification threshold was tested by T&T olfactory assessment.Results Compared with normal control group, the scores of MMSE and montreal cognitive assessment in PD group were significantly decreased ( all P<0.05 ) , age, smoking history, the rate of male had no statistical significance ( all P>0.05 ) .The olfactory identification threshold in PD group was significantly higher than normal control group (t=6.785, P=0.000).Compared with PD smoking subgroup, the olfactory identification threshold in non-smoking subgroup was significantly higher (t=-3.000, P=0.003).The olfactory identification threshold in normal control smoking subgroup was significantly lower (t=0.784, P=0.435). The olfactory identification threshold of PD smokers had no correlation with smoking pack-years or duration ( r=-0.104, P=0.441;r=-0.156, P=0.246) .Conclusion Smoking may protect olfactory disorder in PD patients, and it has no correlation with smoking pack-years or duration.

Objective To study the CT and MRI features of peripheral primitive neuroectodermal tumor(PNET).Methods CT and MRI appearances of 10 patients with PNET pathologically proved were analyzed retrospectively.All cases underwent CT scan and 2 cases underwent MR imaging examination.There were 5 men and 5 women,the age ranged from 11 years to 54 years old(mean 24 years).Results The tumors were located in the chest wall(n=4),abdomen and sinus(n=2,each),cervical vertebra and humerus(n=1,each).The lesions in the chest wall and abdomen appeared as larger masses(5~16 cm in diameter).The masses were circular and lobulated with heterogeneous density and in company with bone destruction or periosteal reaction.The solid masses were enhanced after contrast medium administration.The lesions in the sinus showed the soft tissue mass with bone erosion.The lesions in bone demonstrated local iso-intensity on T1WI,hyper-intensity on FSE T2WI and on FATSAT T2WI.There were distant metastasis in 3 cases.Conclusion The clinical and imaging features of pPNET in chest wall were more specific than in other locations.CT and MRI can showed intra-tumor structure,and are helpful in delineated the extent of tumor,predicting resectability and monitoring treatment.

Objective To study the effects of Danshen Shujingwan on cervical cord compression in rats. Methods 60 healthy male SD rats of 8 weeks old were randomly divided into 6 groups: sham group (N group), model group (M group), DSW groups of high, medium and low dosages, and group treated with Jingfukang (J group), with 10 rats in each. The cervical cord compression models were established by transplanted silica gel. From 7 d after model establishments, the rats were respectively treated with drug by gavage for 30 d. They were observed pathologically. Results The extent and scope of damage were less in the treatment groups than in the model group (P<0.001), while the number of normal neurons remained more in the treatment groups (P<0.01).Conclusion DSW can decrease the damage after cervical spinal cord compression, protect the neurons from injuring.

Objective To investigate the regularity of intrapulnonary lobar and segmental lymph nodes metastasis in patients with cT1N0M0 stage lung adenocarcinoma.To provide a basis for more accurate determination of N stage and indication for pulmonary segmental resection.Methods A prospective study was performed from March 2014 to December 2015.103 cases of cT1 N0M0 stage lung adenocarcinoma received lobectomy and mediastinal lymph node dissection in the thoracic surgery department of China-Japan Friendship Hospital.Intrapulmonary lobar and segmental lymph nodes were dissected and sorted carefully then sent to the pathological department with the corresponding lung specimen and other lymph nodes.Statistical analysis was carried out considering size of the lesion,imaging features,serum CEA levels,pathological subtypes and so on.Results In total 103 cases,pN0 was confirmed in 82 cases,pN1 in 15 cases,pN1 + N2 in 5 cases,and skipping-pN2 in 1 case.14 cases(93.3%) in pN1 group were detected with station 12-14 lymph node metastasis,while only 5 cases (33.3%) were detected with station 12-14 LSNs metastasis.4 cases(66.7%) in pN2 group were detected with station 12-14 lymph node metastasis,while only 1 case(16.7%) with station 13 and station 7 lymph node metastasis.If LSNs were not detected,the false negative rate of N staging could be as high as 6.1% (5/82),The rate of missed diagnosis of lymph node metastasis might be 30% (6/20) to N1 stations alone.41.2% (7/17)cases with metastasis to the adjacent LSNs had been proved with metastasis to the isolated LSNs.The metastasis rate of the isolated LSNs was significantly lower(P =0.049) in pure GGNs compared with those part-solid/solid nodules.Invasive adenocarcinoma had higher metastasis rate of isolated LSNs,compared with preinvasive lesions or minimally invasive adenocarcinomas,with no statistical difference between groups (P =0.055).No significant difference in isolated LSNs metastasis rate was found between groups with different serum CEA levels(P =0.251) or tumor size(P =0.197).Conclusion Dissection of intrapulmonary lobar and segmental lymph nodes might facilitate a more accurate N stage,reduce the false negative rate of lymph node metastasis,and provide basis for more accurate assessment of prognosis and postoperative adjuvant treatment.The sampling area of lymph nodes during segmental resection should include the adjacent LSNs of the target segment.The isolated LSNs metastasis rate of cT1N0M0 stage lung adenocarcinoma with pureGGN as imaging feature is relative low,which might be suitable for segmentectomy when meeting other criteria.

OBJECTIVETo compare the contents of two another anthraquinone-O-glucosides in five different processed products from Rheum palmatum.
METHODAloe-emodin-3-CH2-O-beta-D-glucopyranoside and emodin-8-O-beta-D-glucopyranoside were determined simultaneously by HPLC on an Agilent TC-C18 (2) column at 35 degrees C with the tetrahydrofuran-1% glacial acetic acid (25:75). The detection wavelength was set at 410 nm and the flow rate was 0.9 mL x min(-1).
RESULTThe calibration curves for two components were linear within the range of 0.0090-0.2704 microg (r = 0.9996), 0.0396-1.188 microg (r = 0.9996), and the average recoveries were 97.85%, 97.19% respectively.
CONCLUSIONThe results showed the remarkable variation regulations among the five different processed pieces. The contents of the crude pieces and the pieces roasted vinegar were almost the same, while the pieces roasted with millet wine were a little higher than that of the crude pieces, and the contents at the two components in prepared pieces and charring pieces evidently reduced.
