Abstract
Phytochemical investigation of Lycopodium cernuum L. afforded seven undescribed serratene triterpenoids named 3β, 21β-dihydroxyserra-14-en-24-oic acid-3β-(5'-hydroxybenzoate) (1), 3β, 21β, 24-trihydroxyserrat-14-en-3β-(5'-hydroxyl benzoate) (2), 3β, 14α, 15α, 21β-tetrahydroxyserratane-24-methyl ester (3), 3β, 14α, 21β-trihydroxyserratane-15α-(4'-methoxy-5'-hydroxybenzoate)-24-methyl ester (4), 3β, 14α, 21β-trihydroxyserratane-15α-(4'-methoxy-5'-hydroxybenzoate) (5), 3β-hydroxy-21β-acetate-16-oxoserrat-14-en-24-oic acid (6), 3β, 21β-dihydroxy-16α, 29-epoxyserrat-14-en-24-methyl ester (7), together with eleven known compounds (8-18), whose chemical structures were elucidated through spectroscopic analysis of HRESIMS, 1D NMR, 2D NMR and comparison between the literature. All compounds were evaluated for their α-glucosidase inhibitory activity for the first time. The results showed that compounds 1, 2, 4, 5, 6, 10, 13, 15, and 16 were among the most potent α-glucosidase inhibitors, with IC50 values ranging from 23.22 ± 0.64 to 50.65 ± 0.82 μM. Structure-activity relationship (SAR) studies indicated that the combined properties of the 5-hydroxybenzoate moiety at C-3, β-OH at C-21, COOH- at C-24, and Δ14,15 groups enabled an increase in the α-glucosidase inhibitory effect. In addition, molecular docking studies showed that the potential inhibitors mainly interact with key amino acid residues in the active site of α-glucosidase through hydrogen bonds and hydrophobic forces.

Abstract
Bufonis Venenum,the dried secretion of Bufo bufo gargarizans or B. melanostictus,is toxic and hard with the efficacy of removing toxicity for detumescence and relieving pain. The processing of Bufonis Venenum dates back to the Song dynasty. In addition to the wine-processing,milk-processing and talcum powder-processing,there were some other kinds of processing methods in ancient times,such as baking,calcining,water-soaking and vinegar-processing. Modern studies have shown that the Bufonis Venenum has the main chemical components of bufadienolides,indole alkaloids sterols,and other compounds. It has the pharmacological effects of antitumor,cardiac,antibacterial,and analgesic activities,local anesthesia,and so on. This paper reviews the processing evolution,chemical components and pharmacological effects of Bufonis Venenum,providing references for its special processing and modern research as well as the theoretical basis for the research on its processing mechanism and quality control.

Abstract
Four new stilbene derivatives, hypargystilbenes B-E (1-4), together with seven known compounds (5-11), were isolated from the stems of Artocarpus nanchuanensis S.S. Chang. Their structures were elucidated on the basis of spectral data. Hypargystilbene B, hypargystilbene D, and hypargystilbene E exhibited protein tyrosine phosphatase 1B inhibitory effects with corresponding IC50 values of 3.23, 37.31, and 2.53 nM.

Abstract
Global Positioning System (GPS) measurements in China indicate that crustal shortening accommodates most of India's penetration into Eurasia. Deformation within the Tibetan Plateau and its margins, the Himalaya, the Altyn Tagh, and the Qilian Shan, absorbs more than 90% of the relative motion between the Indian and Eurasian plates. Internal shortening of the Tibetan plateau itself accounts for more than one-third of the total convergence. However, the Tibetan plateau south of the Kunlun and Ganzi-Mani faults is moving eastward relative to both India and Eurasia. This movement is accommodated through rotation of material around the eastern Syntaxis. The North China and South China blocks, east of the Tibetan Plateau, move coherently east-southeastward at rates of 2 to 8 millimeters per year and 6 to 11 millimeters per year, respectively, with respect to the stable Eurasia.

Abstract
A noninvasive study was conducted on intact awake humans to characterize the dynamic response of the heart to the vagus during slow-, comfortable-, and fast-paced respiration (8, 12, and 18 breaths/min), under both sitting and standing conditions. The respiration response curve (RRC) of respiration-associated vagal effects on the heart was estimated, and characteristics of entrainment and frequency dependence on respiration were demonstrated. It was shown that the degree of entrainment and magnitude of phase resetting decrease with increase of pacing rate from 8 to 18 breaths/min. Further, the RRC was examined by overlapping equivalent phase shifts in different respiration cycles. This examination of the RRC can help us not only to find the common pattern underlying the RRC during different respiration cycles but also to perceive its variation related to degree of entrainment.

Abstract
Serum IgG and IgM antibodies against a novel 2,3-diacyl-trehalose-2'-sulphate (SLIV) antigen using ELISA were determined in control (n = 112) and in pulmonary tuberculosis (n = 120) patients. The specificity and sensitivity of SLIV-IgG-ELISA were 96% and 52%, respectively. Those of SLIV-IgM-ELISA were 95% and 33%, respectively. Compared with PPD-IgG-ELISA, SLIV-IgG-ELISA showed that the specificity was about the same but the sensitivity was higher.

Abstract
It has been found that in rats exposed to a noise of 2kHz (mai frequency) and 103 dB(A) (potency) for 60 minutes, the hepatic glycogen content (HGC) is significantly higher than that of the control group unexposed to the noise (P less than 0.05), whereas in those treated with a prior ip Radix Astragali plus noise the HGC appears apparently lower than that of the noise group (P less than 0.05), very close to the control group (P greater than 0.2). This indicates that Radix Astragali might have some antinoise effect.

Abstract
This article introduces the application of compound crystal trichosanthin to 179 difficult cases of artificial abortion including cases with extreme anteversion and anteflexion of uterus with a fine and long cervix, cases with uterine deformations, cases within 1 year after cesarotomy, and cases of recently induced abortion. Past experiences have indicated that there have been considerable difficulties in inducing abortion in such cases as the above, and that accidents have been liable to occur. The authors have recently employed compound crystal trichosanthin, composed of crystal trichosanthin, testosterone propionate and reserpine, and succeeded in bringing about drug expansion of uterus and abortion, and safe abortion at that. The success roles were as follows: 97.96% for the group with extreme anteversion and anteflexion of uterus with a fine and long cervix, 100% for the one with uterine deformations, 95.08% for the one with past cesarotomy and 96.72% for the one with recently induced abortion.

Abstract
The purpose of this study was to observe the safety of the prolonged use of the stainless steel ring. The endometria of 8 women who had had stainless steel ring insertion for 20 years with normal menstruation were examined under the electron microscope. The results were: the pressed area of endometrium showed various degrees of atrophy or degeneration; the adjacent area showed slight degeneration or mild proliferation of the surface epithelium, few cells with hypertrophy or metaplasia; no apparent malignant changes had been found. The remote area did not show any apparent pathological changes. It seems their hormonal reactions were relatively normal, and even sensitive structures such as N.C.S. and giant mitochondria still appeared. Thus, there seemed to be no severe endometrial destruction or malignant changes. In correlation with clinical analysis, it is suggested that the prolonged use of the stainless steel ring for as long as 20 years seems to be safe.

Abstract
The Copper T 200 in Shanghai has been found to be a very efficient method of contraception in parous women. 856 insertions were done during the period starting December 27, 1973 to September 30, 1974. A total of 33,566 woman-months was included in the five-year study period. Life-table analysis of data showed the cumulative pregnancy rate to be 4.84, expulsion rate 5.74 and medical removal rate for bleeding or pain to be 22.51 per 100 women. According to the time of insertions, 856 users were divided into three groups; post-abortal 487, post-menstrual 264 and nursing period 105. Comparison of results revealed that the cumulative pregnancy rate of the post-abortal group, 2.67 per 100 women, was lower than those of both the post-menstrual group, 6.44 per 100 women, and the nursing period group, 10.48 per 100 women (P less than 0.05). The Copper T 200 is effective at the end of five years of insertion, and post-abortal insertion gives better protection without increased risk of complications. We propose that the Copper T 200 may be used for five years or even longer.
