China Pharmacy 2005;0(16):-
OBJECTIVE:To provide reference for definition and research & development of new drugs in China.METHODS:The history of the definition for new drugs was reviewed,and the effects of the definition of new drugs on the research and development of drugs were discussed by using the game theory "Tragedy of the Commons" and "Anti-Tragedy of the Commons".RESULTS & CONCLUSIONS:The definition of new drugs should be more and more scientific and reasonable and in line with the aim of building new creative country,meanwhile,efforts should be paid to avoid the above mentioned two kinds of tragedies.

Objective To study the relationship between tyrosine phosphorylation(TP)and protein expression of insulin receptor substrate-1(IRS-1)and insulin resistance in patients with gestational diabetes mellitus(GDM).Methods IRS-1 expression and TP in skeleton muscle tissue were determined by Western blot and immunoprecipitation in women with GDM(GDM group,n=22),normal pregnant women(normal pregnancy group,n=22)and normal nonpregnant women(normal nonpregnant group,n=13).Fasting plasma glucose(FPG)and fasting insulin(FINS)were measured by oxidase assay and immunoradioassay. Results(1)The levels of FPG,FINS,and insulin resistance index were calculated according to homeostasis model assessment [ HOMA-IR;(5.6?0.8)mmol/L,(15.4?5.1)mU/L,and 1.2?0.5 ] in GDM group were significantly higher than those in normal pregnancy group [(4.4+0.5)mmol/L,(10.6 ?3.1)mU/L,and 0.8?0.3;P

OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.
METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.
RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).
CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

Abstract: Objective To investigate the pollution of paralytic shellfish poisons (PSP) in shellfish sold in Hainan Province from 2018 to 2021. Methods From 2018 to 2021, the content of 10 paralytic shellfish poisons including saxitoxin (STX), neosaxitoxin (neoSTX), gonyautoxins 1 (GTX1), gonyautoxins 2 (GTX2), gonyautoxins 3 (GTX3), gonyautoxins 4 (GTX4), gonyautoxins 5 (GTX5), decarbamoylsaxitoxin (dcSTX), decarbamoylgonyau toxins 2 (dcGTX2) and decarbamoylgonyau toxins 3 (dcGTX3) in 7 kinds of shellfish commonly sold in 13 cities and counties in Hainan province was analyzed. Results The detection rate of PSP in 360 shellfish samples was 10.3%. Among them, the highest detection rate of STX was 5.83%, followed by GTX2 detection rate of 4.17%; the detection rate of neoSTX and GTX3 were both 1.67%; the detection rate of GTX1 was 1.39%. None of the five PSP, GTX4, GTX5, dcSTX, dcGTX2 and dcGTX3, were detected. Four types of PSP were detected in fanscallops, two were detected in oysters, mussels and Scapharca subcrenata, only one was detected in scallops, and no toxin contamination was detected in clams and razor clams. A single sample of fanscallops detected a maximum of 4 PSP, and a single sample of oysters, scallops, mussels and Scapharca subcrenata detected a maximum of 1 PSP. The equivalence of PSP in all samples was ND-155.6 μg/kg.The annual detection rate of PSP from high to low was: 20.0% in 2020, 15.6% in 2019, 5.3% in 2018, and 2.0% in 2021, and none of the samples tested exceeded the standard. Continuously detectable STX in 2018-2020, all PSP that could be detected in 2018 were STX. In 2019, in addition to STX detected in scallops and Scapharca subcrenata, neoSTX was also detected in oysters, mussels and Scapharca subcrenata. In 2020, PSP was only detected from scallops, and GTX2 could be detected in all positive specimens, while 5 STX, 5 GTX1 and 6 GTX3 were detected. Only GTX2 detected from scallops in 2021. STX was detected in shellfish sold in 12 cities and counties, GTX2 can be detected in 10 cities and counties, neoSTX can be detected in 5 cities and counties, GTX1 and GTX2 were detected in 4 cities and counties respectively. Shellfish sold in Wenchang and Lingshui markets can detect 5 types of PSP. Conclusion Some types of shellfish on the market in Hainan are contaminated with some kind of PSP pollution risks, and it is necessary to strengthen the supervision of PSP in marketed shellfish.

BACKGROUND:Polyhydroxybutyrate-co-volerate (PHBV) is a noticeable tissue engineering material of polyhydroxyalkanoates family. It has the properties of low immune rejection response and good biocompatibility, and its degradation products are non-toxic.
OBJECTIVE:To investigate the biocompatibility of PHBV membrane material and human bone marrow mesenchymal stem cel s in vitro.
METHODS:Human bone marrow mesenchymal stem cel s at passage 3 were seeded upon PHBV membrane as experimental group and upon conventional culture plates as control group. Then we calculated the adherent cel number of two groups at 1, 2 and 4 hours and got the cel adherent rate. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide assay was used at days 2, 4, 6, 8 to observe the cel proliferation of two groups. Fluorimetric method with the fluorescent dye Hoechst 33258 was used to detect the DNA content of cel s at days 3, 6, 9 and 12 in both groups. After cel s were seeded upon PHBV membrane for 5 days, the cel growth upon the material was examined under a scanning electron microscope.
RESULTS AND CONCLUSION:When the cel s were cultured for 1 hour, the adherent rate in the experimental group was lower than that in the control group;but there were no significant differences between two groups at the other two periods. No difference was found in the cel proliferation and the DNA content between the two groups. Human bone marrow mesenchymal stem cel s seeded upon PHBV membrane for 5 days grew wel with spindle morphology and the intercel ular connections were tight and more extracel ular matrices were observed by scanning electron microscopy. Taken together, PHBV membrane material shows a good biocompatibility with human bone marrow mesenchymal stem cel s.
