The research on clinical efficacy evaluation of traditional Chinese medicine (TCM) is a hot and difficult issue in the field of TCM. However, the overall level of current related research also needs to be improved. There are still a lot of academic controversies in the field of TCM clinical efficacy evaluation. The author believed that before conducting research, it is necessary to sort out core issues of TCM clinical efficacy evaluation, which in-clude the concept of TCM clinical efficacy and its evaluation. In recent years, Chinese scholars have conducted a series of studies on these issues and have some achievements. To think and answer these questions will play an important role for the ultimate resolution of problem of TCM clinical efficacy evaluation.

Through analyzing the current situation and coverage controversy of Chinese clinical trial insurance,this paper stated that the attending insurance rate in domestic clinical trials was entirely low.The sponsors,clinical trial institutions,investigators and insurance companies paid attention of different levels to clinical trial insurance.Therefore,the risk awareness of drug/medical device clinical trials should be enhanced.It is necessary to give impetus to clinical trial insurance system,during which all parties need to make a joint effort including government departments,ethics committees,sponsors,clinical trial institutions,investigators and insurance companies.

The clinical, pathological features and diagnostic methods of one case of adult-onset neuronal intranuclear inclusion disease (NIID) were analyzed. The patient was 61-year-old female presented with progressive cognitive impairment, episodic unconsciousness, stroke-like attack and paroxysmal digestive tract symptoms. Diffusion-weighted images showed high signals at the cerebral cortico-medullary junction with lace-type distribution, which persisted. Skin biopsy revealed intranuclear inclusion bodies in adipocytes, fibroblasts, and sweat gland cells. This case suggests that adult neuronal nuclear inclusion disease is a chronically progressive neurodegenerative disease with a highly clinical heterogeneity. The subcortical lace sign and eosinophilic intranuclear inclusion bodies by skin biopsy contribute to the diagnosis.

OBJECTIVETo explore the experimental method of obtaining position emission tonogiaphy (PET) imaging evidence of changes in cerebral function by puncturing the Stomach 36 (ST36, Zusanli) acupoint.

METHODSData on changes of cerebral glycometabolism were obtained from six healthy male volunteers with positron emission tomography. Visual experimental evidence, as well as statistical parametric mapping (SPM), was gathered while puncturing the ST36 (Zusanli, right leg) acupoint.

RESULTSThere was increased glycometabolism in the hypothalamus, head of the caudate nucleus, temporal lobe, the sinistral cerebellum, postcentral gyrus, and brain stem while the acupoint ST36 was being punctured.

CONCLUSIONSAcupuncture on ST36 can lead to increase in glycometabolism in the vegetative nerve centers, which is correlated with gastric function. Visual experimental evidence of ST36 acupuncturing on functional gastrointestinal disorder was obtained in our study.

Objective To evaluate the bioequivalence of domestic and imported terazosin hydrochloride tablets after single oral dose .Methods It was a single center ,randomized ,open ,cross-over trail design ,21 subjects were fasting oral adminis-tered of 2 mg domestic and imported terazosin hydrochloride tablets in different periods ,venous blood 4 ml were collected in different time points before and 60 h after administration ,plasma concentration of terazosin was determined by LC-MS/MS . Results The main pharmacokinetic parameters of domestic and imported terazosin hydrochloride tablets were as follows :t1/2 :(13.2± 2.39)hvs(12.5±1.93)h,tmax :(1.01±0.83)hvs(1.08±0.69)h,Cmax :(40.1±10.6)ng/mlvs(37.3± 9 .57) ng/ml;AUC0- ∞ :(428 ± 82 .1) ng · h/ml vs (426 ± 85 .2) ng · h/ml .The relative bioavailability of domestic terazosin hydrochloride tablets was (101 .2 ± 14 .7)% .90% CI of domestic and imported terazosin hydrochloride tablets AUC0-t and Cmax geometric mean ratio fell between 80% -125% .Conclusion The domestic tablets are bioequivalent to the imported tablets .

Objective:To investigate the relationship between the serum alkaline phosphatase (ALP), prostate specific antigen (PSA) and bone metastasis in initially diagnosed prostate cancer (PCa) patients in different ISUP(International Society of Urological Pathology)groups.Methods:The 368 initial diagnosed prostate cancer patients recruited from January 2013 to December 2018 were retrospectively analyzed, including 247 cases in the Third Affiliated Hospital of Sun Yat-sen University, 111 cases in the Yuebei People's Hospital Affiliated to Medical College of Shantou University and 10 cases in Shenzhen Hospital of Southern Medical University. According to whether there was bone metastasis at the initial diagnosis, it was divided into 230 cases in the bone metastasis group and 138 cases in the non bone metastasis group. There was no significant difference between the two groups in age [(71.9±9.4) years and (71.2±8.7) years], body mass index (BMI) [(23.1±3.7) kg/m 2 and (23.7±2.6) kg/m 2]. There were significant differences in PSA [(307.3±847.0) ng/ml and (84.5±257.3) ng/ml] and ALP [(174.5±270.8) U/L and (71.0±23.2) U/L] between the two groups. In different PSA subgroups, there were 45 cases in PSA <10 ng/ml, 35 cases in PSA 10-20 ng/ml and 288 cases in PSA >20 ng/ml. The differences of ALP and PSA between bone metastasis group and non-bone metastasis group based on different ISUP stratification were analyzed, ROC curves were used to predict their risks of bone metastasis. Results:There were 3(1.3%), 22(9.6%), 34(14.8%), 85(37.0%) and 86 (37.4%) prostate cancer patients with bone metastasis from ISUP group 1 to 5, and 14(10.1%), 19(13.8%), 29(21.0%), 32(23.2%) and 44(31.9%) without bone metastasis, respectively. There was significant difference in the serum ALP levels between the bone metastasis group and the boneless metastasis group in the ISUP group 4(157.6±207.7 vs. 66.5±17.0) and 5(189.4±257.5 vs. 69.2±18.4)( P<0.001) and PSA levels had difference in the ISUP group 3(240.3±313.0 vs. 42.4±42.1), 4(152.3±184.5 vs. 44.7±33.3) and 5(435.2±1006.3 vs. 60.8±84.8)( P<0.001). There was statistically significant between the bone metastasis group and the without(336.1±882.2 vs. 139.3±328.1) when PSA>20 ng/ml( P=0.006). ROC curve analysis: the cut-off values of ALP were 115.5, 109.0, 75.5 and 86.0 U/L from ISUP group 2 to 5 respectively, the sensitivity was 23.8%, 56.5%, 66.4% and 50.6% respectively, the specificity was 99.7%, 93.4%, 78.3% and 89.2% respectively, and the accuracy were 59.4%, 73.1%, 69.7% and 63.3%, respectively. The cut-off values of PSA were 39.5, 93.1, 54.2 and 28.9 ng/ml from ISUP group 2 to 5 respectively, the sensitivity was 64.4%, 68.4%, 87.4% and 88.3% respectively, and the specificity was 79.5%, 90.6%, 63.7% and 61.6% respectively, and the accuracy were 71.6%, 78.1%, 80.1% and 79.2%, respectively. Conclusion:ALP increased significantly in ISUP group ≥4 and PSA in ISUP group ≥3, which related to bone metastasis in patients with initial diagnosed prostate cancer.
