Objective: To observe the clinical efficacy of acupuncture plus bloodletting therapy in treating insomnia in people with blood stasis constitution. Methods: Seventy-two patients were randomized into a treatment group and a control group by using the random number table, 36 cases each. The treatment group received acupuncture plus bloodletting therapy, while the control group was intervened by oral administration of estazolam. One-week treatment was taken as a course, for 3 successive courses in total. A follow-up study was conducted 3 months later. The Pittsburgh sleep quality index (PSQI) was evaluated before and after the intervention, as well as in the follow-up. The clinical efficacies were also compared. Results: The total effective rate was 88.9% in the treatment group versus 83.3% in the control group, and the between-group difference was statistically significant (P<0.05). After the intervention, the PSQI scores dropped significantly in both groups (both P<0.05); the between-group difference in PSQI score was statistically significant (P<0.05). The follow-up study showed that the between-group difference in the global score of PSQI was statistically significant (P<0.05). Conclusion: Acupuncture plus bloodletting therapy can produce a more significant efficacy than oral administration of estazolam in treating insomnia in people with blood stasis constitution.

Objective To explore the association between the infection of human cytomegalovirus(HCMV),herpes simplex virus typeⅠ(HSV-Ⅰ),HSV-Ⅱ,toxoplasma(TOX) and serum hepatitis B virus(HBV)these 5 pathogens and low body weight and pneumonia,and explore the clinical value of nested polymerase chain reaction (PCR) examining newborns infected with pathogens.Methods Forty-six newborn infants with low weight and 66 newborn infants with pneumonia were selected.And 1 mL pripheral blood of every newborn infant was drawn.Classic phenol-chloroform-isoamyl alcohol-protease digested,after neonatal serum extraction of DNA in peripheral blood through 2 pairs of pri-mers,the outer primer amplified larger DNA fragments and the inner primer amplified small fragments,in the amplified products.HCMV,HSV-Ⅰ,HSV-Ⅱ,TOX and HBV of the viral DNA in highly conservative district to design primer respectively and amplify its viral DNA,nested PCR was used to detect of these pathogens DNA in infants of low body weight and pneumonia,and to detect positive rate of infection.Screening for birth defects in infants in these virus infection.SPSS 10.0 software was used to analyze the relationship between infection of 5 pathogens.Results The infective rate of HCMV in 46 infants with low body quality was 91.3%,the infective rate of HSV-Ⅰwas 8.7%,the infective rate of HSV-Ⅱwas 15.2%,the infective rate of TOX was 8.7%,and the infective rate of HBV was 15.2%.Among 66 infants with pneumonia,the infective rate of HCMV was 83.3%,the infective rate of HSV-Ⅰwas 6.1%,the infective rate of HSV-Ⅱwas 16.7%,the infective rate of TOX was 6.1%,and the infective rate of HBV was 7.6%.The infective rate of HCMV was higher than that of other 4 pathogens,these infection rates were different statistically in these 5 kinds of pathogens(Pa=0).Conclusions Five kinds of pathogens both low pathosens screening is necessary newborns infants with low body weight and pneumonia,and for the early diagnosis and prevention of these pathogens.

To reveal the characterization of interaction between Chinese and western medicinal injections, isothermal titration calorimetry (ITC) was applied to evaluating the interaction of Yiqi Fumai injection (YQFM, as mode drug) with epinephrine hydrochloride injection (YS) and 5% glucose injection (5% GS). The diversification of Gibbs free energy (ΔG), enthalpy (ΔH), and entropy (ΔS) were determined to judge the reaction types of colliquefaction procedures of different injections. Meanwhile, the fingerprints of YQFM before and after combined with the various injections were compared to validate the results. This work demonstrated that during the titration procedure of YQFM and YS, [ΔH] > T [ΔS] , that was to say the reaction was enthalpy-driving. And the reactive profile indicated that a great deal of heat gave out during the procedure. Obviously, chemical reactions happened and the internal component changed. On the other side, the reaction of YQFM combined with 5% GS was entropy-driving, because [ΔH] < T [ΔS]. The reactive profile showed there was only a little heat released. So non-chemical reactions happened and the major ingredients did not change. ITC could be applied to the evaluation on compatibility of other kinds of Chinese and western medicinal injection combination.

The establishment of high specificity and sensitivity method of small molecule monoclonal antibody-based immunoassay has a great importance in the study of small molecule compounds in Chinese medicine, wherein synthesis of small molecule artificial antigen is a critical step in the preparation of small molecule antibodies. Oxidation method using sodium iodide was used to synthesize immunogenic antigen (FRn-BSA) and coating antigen (FRn-OVA) of forsythin. UV spectroscopy and thin layer chromatography showed that forsythin was successfully conjugated with BSA and OVA. After immuned FRn-BSA, the mice could specifically produce anti-forsythin antibodies with titer up to 1:8 000, and the linear range was from 1 mg x L(-1) to 100 mg x L(-1). In this paper, the artificial antigen of forsythin was successfully synthesized, which can be applied for preparation of monoclonal antibodies and establishment of appropriate immune method.

OBJECTIVETo investigate the incidence of seroresistance of syphilis and analyze its relevant factors.

METHODSThe clinical data of 131 patients with syphilis were retrospectively analyzed. The incidence of seroresistance was investigated and the correlation between seroresistance and factors including age, gender, original titer, disease course, and medications were analyzed.

RESULTSThe incidence of seroresistance was not significantly different among patients with different ages and genders, but was significantly different among patients with different disease courses, antibody titers, and medications. Patients with a baseline serum rapid plasma reagin (RPR) titer of greater than 1: 8, a latent course, or a macrolide therapy history had higher incidences of seroresistance (i. e., 61%, 45.6%, and 72.7% respectively) than those who had a lower RPR titer, a primary course, or a benzathine penicillin therapy history.

CONCLUSIONSyphilis patients with a high baseline RPR titer, a latent course, and a macrolides therapy are prone to be seroresistant.

Objective To study the prevalence of human immunodeficiency virus(Hiv),sexually transmitted infection(Sti),risk behavior and the sexual neworks among men who have sex with men (MSM)in Taizhou city，Zhejiang province.Methods cross-sectional Astudy was applied with venue-based sampling in 2 MSM gathering sites in Taizhou.'Informed Consent'principle was applied and MSM were studied through a structured questionnaire．Blood samples were collected from thee who accepted free and confidential HIV/STI counseling and then tested for HIV,syphilis,HCV and HsV-2 antibodies with ELISA.HIV positive sera were certified with western blot．Results 106 MSM were investigated and 97 qualified questionnaires were collected.25.0％(23/92)of these MSM have ever had l female sex partner while 47.8％(44/92)had 2 or more.14.3％(13/91)of them reported having had 1 male partner who had engaged in anal sex and 80.2％(73/91)had 2 or more.22.1％(19／86)of therh had partieipated in group sex but 62.5％(55／88)of them did not always use condom when having analintercourse.15.1％(14／93) of them had l orfll sex partner while 75.3％(70／93)having 2 or more.38.9％(37／95)of them had sex with female sex worker,and 35.5％(33／93)had sex with male-to-male sex worker.15.3％(13/85)0f them had once been male-to-male sex worker themselves.3.9％(3/77)of them were found HIV positive in blood tests,with 24.7％(18/73)positive of syphilis,15.1％(11/73)positive ofHSV-2 but HCV appeared to be negative.46 csses reported their egocentric recognition networks,with mean degree of 5.91(ranging0-10),and mesa density of 0.548(ranging 0．000-1.000).43 sexual networks were identified,with mean degree of 2.70(ranging 0-10),and mean density of 0.246(ranging 0.000-1.000).Conclusion Risk behaviors,such as multiple sex partners，IOW proportion of condom use and commercial sex engagement both with heterosexuals and homosexuals,were extensively existed among MSM in Taizhou,and the prevalence of HIV/STI was relatively high.Their sexual networks seemed complicated but there might be in place of some sukstantiaUy isolated MSM groups with high risk of Hlv/sTl infection.More study should be applied to identify the relationship between scxual networks and HIV/STI transmigsion.

OBJECTIVETo summarize the epidemiological, clinical and serological features of syphilis.

METHODThe clinical data of 1125 patients with syphilis were retrospectively analyzed.

RESULTSNon-marital sexual intercourse is the main route of infection. The 129 cases of primary syphilis were featured by extragenital chancres and the 357 cases of secondary syphilis were featured by scaling macules on the palms and soles and condylomata lata. Early latent syphilis were detected in 178 cases, late latent syphilis in 174 cases, and latent syphilis of unknown duration in 285 cases. Concurrent infection with other sexually transmitted diseases were noted in 107 cases (9.51%). Most patients were treated with benzathine penicillin, and only 31 patients (2.75%) were allergic to this therapy. Except for the primary syphilis, the sensitivity of syphilis serological tests (including rapid plasma regain test, treponema pallidum particle agglutination, treponema pallidum hemagglutination assay, and fluorescent treponemal antibody-absorption) were higher than 97%.

CONCLUSIONSThe incidence of latent syphilis is high, while the incidence of late syphilis is low. Penicillin remains the treatment of choice for syphilis.

OBJECTIVETo study source apportionment of atmospheric PM10 (particle matter ≤ 10 µm in aerodynamic diameter) and PM2.5 (particle matter ≤ 2.5 µm in aerodynamic diameter) in Beijing,Urumqi and Qingdao, China.

METHODSThe atmospheric particle samples of PM10 and PM2.5 collected from Beijing between May 17th and June 18th, 2005, from Urumqi between April 20th and June 1st, 2006 and from Qingdao between April 4th and May 15th, 2005, were detected to trace the source apportionment by factor analysis and enrichment factor methods.

RESULTSIn Beijing, the source apportionment results derived from factor analysis model for PM10 were construction dust and soil sand dust (contributing rate of variance at 45.35%), industry dust, coal-combusted smoke and vehicle emissions (contributing rate at 31.83%), and biomass burning dust (13.57%). The main pollution element was Pb, while the content (median (minimum value-maximum value)was 0.216 (0.040-0.795) µg/m(3)) . As for PM2.5, the sources were construction dust and soil sand dust (38.86%), industry dust, coal-combusted smoke and vehicle emissions (25.73%), biomass burning dust (13.10%) and burning oil dust (11.92%). The main pollution element was Zn (0.365(0.126-0.808) µg/m(3)).In Urumqi, source apportionment results for PM10 were soil sand dust and coal-combusted dust(49.75%), industry dust, vehicle emissions and secondary particles dust (30.65%). The main characteristic pollution element was Cd (0.463(0.033-1.351) ng/m(3)). As for PM2.5, the sources were soil sand dust and coal-combusted dust (43.26%), secondary particles dust (22.29%), industry dust and vehicle emissions (20.50%). The main characteristic pollution element was As (14.599 (1.696-36.741) µg/m(3)).In Qingdao, source apportionment results for PM10 were construction dust (30.91%), vehicle emissions and industry dust (29.65%) and secondary particles dust (28.99%). The main characteristic pollution element was Pb (64.071 (5.846-346.831) µg/m(3)). As for PM2.5, the sources were secondary particles dust, industry dust and vehicle emissions (49.82%) and construction dust (33.71%). The main characteristic pollution element was Pb(57.340 (5.004-241.559) µg/m(3)).Enrichment factors of Zn, Pb, As and Cd in PM2.5 were higher than those in PM10 both in Beijing and Urumqi.

CONCLUSIONThe major sources of the atmospheric particles PM10 and PM2.5 in Beijing were cement dust from construction sites and sand dust from soil; while the major sources of those in Urumqi were pollution by smoke and sand dust from burning coal. The major sources of the atmospheric particles PM10 in Qingdao were cement dust from construction sites; however, the major sources of PM2.5 there were secondary particles dust, industry dust and vehicle emissions. According to our study, the heavy metal elements were likely to gather in PM2.5.

Objective To explore the extracts of solanum nigrum to treat plasma cell myeloma ostealgia. Methods A total of 60 patients with plasma cell myeloma ostealgia were randomly divided into experimental group and control group, 30 cases in each group. The patients in the experimental group were given extracts of Solanum nigrum electroosmotic nursing, while the patients in the control group only received routine nursing care. Ostealgia improvement, application of analgesic and adverse reaction were compared between the two group. The improvement of ostalgia was observed in two groups, as well as application and adverse effects of analgesic, and the differences of two groups were compared by Fisher exact probability. Results The ostalgia control rate of the experimental group was 96. 6% compared with 46. 6% of the control group (P<0. 05). At the 15th day of treatment, there were 2 patient of the experimental group and 7 patients of the control group (P<0. 05). 3 cases of toxicity happened in the experimental group. Conclusions The extracts of solanum nigrum can relieve ostealgia for plasma cell myeloma patients, and reduce the use of analgesics.

Objective To predict fetal distress in oligohydramnios fetuses in mid-pregnancy by monitoring the blood flows in middle cerebral artery,renal artery and umbilical artery by means of ultrasound.Methods Totally 104 mid-pregnancy women with oligohydramnios in some hospital from January 2020 to May 2022 were selected retrospectively,and were divided into a distress group(n=43)and a non-distress group(n=48)based on the presence of fetal distress.Logistic multivariate regression was used to analyze the risk factors for the occurrence of fetal distress;the predictive value for fetal distress was assessed with ROC curves;a Bayesian network model was constructed and validated.Results The independent risk factors for fetal distress included abnormal findings in fetal movement,fetal cardiac monitoring,lipid levels and blood rheology indices and abnormal parameters of middle cerebral artery,renal artery,and umbilical artery(P＜0.05).Higher predictive efficiency could be obtained for fetal distress when the blood flow parameters of middle cerebral artery,renal artery and umbilical artery were combined than only the parameters of only one artery were involved in.The Bayesian network model predicted an increase in the incidence of fetal distress from 49.9％to 61.50％when the probability of abnormality in all the three artery parameters was 100％,which proved to gain a high net benefit.Conclusion For mid-pregnancy women combined monitoring of the blood flow parameters of middle cerebral artery,renal artery and umbilical artery may predict fetal distress effectively.[Chinese Medical Equipment Journal,2024,45(5):60-66]
