Journal of Third Military Medical University 2003;0(10):-
Objective To study the role of zymosan in and the effects of total saponin of Panax notoginseng (PNS) on the formation of foam cells originating from peritoneal macrophages. Methods The peritoneal macrophages of mice were cultured with zymosan, PNS and oxidized low density lipoprotein (ox-LDL) for 48 h. The shape of the foam cells was shown with the staining of red oil O dye. The content of total cholesterol (TC) in the foam cells was determined. The concentration of TNF? and IL-1 in the supernatant of the cell culture was measured. Results The TC content and the concentration of TNF-? and IL-1 were significantly higher in the zymosan group than in the PNS group. Conclusion Inflammation can accelerate the formation of foam cells through the pathway of inflammatory cytokines but PNS can reduce the formation with the inhibition of inflammation.

Objective To explore the effects of two air sampling methods including natural precipitation method and impacting method for detecting the bacterial count of indoor air of workplace of cosmetic plants. Methods The diameters of 44 glass bacteria-culture plates for those two sampling methods were measured. The indoor air of workplace of cosmetic plants were sampled by those two sampling methods simultaneously. The natural precipitation method was performed for 5- minute exposure ,the impacting method was performed by MAS-100 airborned bacteria sampler at flow rate of 100 L/min for 30 s,2 min,8 min respectively.All of the data on the bacterial counts of air obtained from various sampling ways were statistically analyzed.The measures for quality control of air sampling progress were put forward also. Results The diameters of 44 glass bacteria-culture plates were 8.39-8.70 cm,which were lower than the standard(9 cm?雪. The bacterial counts of air samples collected by natural precipitation method at the same location showed higher coefficient of variation,higher median,lower qualified rate compared with those by impacting method. The bacterial counts of air decreased,when the impacting sampling method was performed for 8 min continuously with sampling volume of 800 L. Conclusion The impacting method with advantages including mere influence from external environment and better precision could be primarily applied for air sampling in general condition,but it might show lower efficiency of collecting the airborne bacteria during the longer sampling period with higher sampling volume. The natural precipitation method with poor precision was suitable for longer term (8-30 min)air sampling in the relatively static environment with lower air flow and highly cleaned air. The bacterial counts of air obtained from natural precipitation method should be corrected if the diameters of glass bacteria-culture plates weren't meet the requirement of the national standard (9 cm?雪.

OBJECTIVETo explore a safe and effective scheme of analgesic for labor.
METHODSEighty-four primiparas without contraindication of vaginal delivery were divided into an observation group and a control group, 42 cases in each one. In the observation group, the acupoint injection was given at Zusanli (ST 36) combined with electroacupuncture (EA) at Hegu (LI 4) and Sanyinjiao (SP 6) till the cervical opening at the end of first stage labor. In the control group, the routine respiratory instruction was applied. In 5 min, 10 min and 60 min of acupuncture (the same time points in the control group) as well as at the end of the first and second stage labor, the analgesic effect was assessed for the primiparas of the two groups. The labor stages, adverse reactions, postpartum hemorrhage, postpartum urine retention, newborn asphyxia rate and usage rate of oxytocin were compared between the two groups.
RESULTSIn the observation group, in 5 min, 10 min and 60 min of acupuncture as well as at the end of the first and second stages, the visual analogue scale (VAS) was lower apparently as compared with the control group at the corresponding time points (all P < 0.05). The differences in the time limit in the active period, the second and third stages were not significant between the two groups (all P > 0.05). The incidence of adverse reactions and the usage rate of oxytocin were lower than those in the control group [2.4% (1/42) vs 31.0% (13/42); 2.4% (1/42) vs 23.8% (10/42), both P < 0.05]. The differences in postpartum hemorrhage, postpartum urine retention and newborn asphyxia rate were not significant between the two groups (all P > 0.05).
CONCLUSIONThe combination of acupoint injection and EA is the effective analgesic scheme for labor. This scheme effectively alleviates labor pain and has no maternal and child complications.

ObjectiveTo investigate the distribution of human immunodeficiency virus-1 (HIV-1)subtypes and the relationship with transmission routes in Shenzhen city. MethodsThe epidemiological survey was conducted in 429 subjects with HIV-1 infection.Vein blood was collected and prepared with anticoagulation.Thereafter,the viral nucleic acid was extracted and subsequently amplified for HIV-1 env,gag genes by reverse transcription nested polymerase chain reaction. The viral sequences were analyzed using Mega software and compared with those in HIV database. The HIV-1 subtypes were confirmed and evolutionary tree was established. The gene discrete rate of different subtypes was calculated.ResultsFour hundred qualified samples were identified as CRF01_AE (n=207),CRF07_BC (n=115),CRF08 _BC (n=14),CRF02_AG (n=1),B (n=49) and C(n=14),respectively.CRF01_AE was the predominant subtype that was detected in the subjects with different transmission routes,such as homosexual contact,heterosexual contact,intravenous drug use and hospital-acquired infection. Among these,sexual contact was the most common route.There were nine cases infected with subtype B HIV-1 in 10 case who were blood borne. The gene discrete rate was more significant in subtype B HIV-1 compared to the other subtypes.According to the evolutionary tree analysis,the viruses under the same subtype formed the relatively independent clusters by different transmission routes. But some overlaps were observed as well. Conclusions Tbere are many HIV-1subtypes in HIV-1 infected subjects in Shenzhen, while the recombinant viruses present as the predominant form.Transmission routes are various with sexual contact as the most common route.Every subset distributes unevenly and forms its own characteristic.Overlap can be observed among the gene distribution of different HIV-1 subtypes.

Objective Exploration of TSH, FT3, FT4 changes in critical condition prior to death.Methods 84 patients that were anti-tumor therapy acceptable and not associated with the treatment of thyroid disease in patients with terminal tumors. Age from 24 to 85-year-old, male 56, female 28. The use of SELDI technology (surface-enhanced laser description / ionization time-of-flight mass spectrometry protein chip technology) checks to M/Z for the 11 100 + H~11 900 + H peak of the cluster, divided into the positive group for critically ill patients with early warning protein (LGT) and the negative group for it. All patients were given TSH, FT3, FT4 inspection. The results were statistically analyzed. Results TSH, FT3, FT4 in the LGT positive group was significantly lower than in the negative LGT group. There was no correlation between TSH,FT3 and FT4 in the LGT positive group;In the negative LGT group FT3 and FT4 had a positive correlation,and FT3 and TSH no relevance. Conclusion Thyroid function is normal in the stage of cancer patients stable condition. Possible pituitary-hypothyroidism may occur as the disease advances to the end or before death.This may be an important factor causing the acceleration to the death of the patients. However, the cause and effect between this phenomenon and the early warning of protein fingerprint group(LGT) is still not clear. In critical condition checking thyroid function and render supplementary amount of thyroid hormone in accordance with the checking results may be beneficial.
