OBJECTIVETo measure the axial rotation angles of the carpometacarpal joints during the digital opposition of thumb-index finger, thumb-medial finger, thumb-ring finger, thumb-little finger and the thumb's maximal opposition, then the application of these parameters were studied.
METHODSTwenty neutrality-occupation volunteers (female 10, male 10) with no history of hand injuries or related diseases were involved in the study. First, all the markers' 3-D coordinates were obstained using the 3D motion analysis system (EVaRT4.1) during the digital opposition movements of thumb. Then, the axial rotation angles were calculated.
RESULTSThe average rotation angles of carpometacarpal joints during all kinds of digital oppositions were 29.1 degrees +/- 9.4 degrees (male), 24.8 degrees +/- 10.2 degrees (female), while the maximal rotation angles are: 35.3 degrees (male), 28.8 degrees (female).
CONCLUSIONSThe combination of video-based 3-D analysis system and mathematics make it possible to measure the axial rotation angles of thumb in vivo, as a result, the rotation angles of thumb carpometacarpal joints are measured precisely for the first time. These results can provide a few parameters for treatment and rehabilitation of carpometacarpal arthrositis.

OBJECTIVETo study the newborn's Apgar score in 'one minute' and relevant factors.
METHODSOne year inpatient woman from a Maternal and Child Health Hospital of Anhui province were selected by cluster sampling method and newborn asphyxia situation was investigated using Apgar score and self-designed questionnaire.
RESULTSThe Apgar score in 'one minute' which marking 8 to 10, 4 to 7 and 0 to 3 were found in 1875 (73.78%), 426 (16.77%) and 240 infants (9.45%) respectively. The average Apgar score in 'one minute' and five minutes were (7.69 +/- 2.27) and (9.01 +/- 1.89) respectively, The Apgar score in 'one minute' was significantly correlated with that of five minutes (Pearson coefficient correlation r = 0.841, P = 0.00). Ordinal regression analysis revealed that parturient age (OR = 1.04), being farmer (OR = 2.22), parity (OR = 1.26), assistant vaginal delivery (OR = 4.93), caesarean section (OR = 1.95), pregnancy-induced hypertension syndrome (OR = 1.42), albuminuria in gestational period (OR = 1.44), newborn being male (OR = 1.23), low birth weight (OR = 2.94), inborn abnormality (OR = 12.12), premature birth (OR = 1.22) and complications of delivery (OR = 5.04) were risk factors while the number of years under study (OR = 0.91), prenatal check-up (OR = 0.48), body length of newborn infant (OR = 0.88) and single birth (OR = 0.57) were protective factors.
CONCLUSIONApgar score in 'one minute' of newborn infant was affected by several factors as stated above. Health care program in earlier period toward community parturient should be strengthened in order to discover and control high risk factors of duration of pregnancy in earlier period.

OBJECTIVETo study the epidemiological pattern and trends of hepatitis B virus (HBV) in the area where people had been immunized by HBV vaccine for long time.
METHODSThrough cluster sampling and cross-sectional study, relative information and blood samples from people in Long-an county by families were collected. Signals of HBV infection were tested by solid-phase reverse immunosorbent test.
RESULTS(1) The average HBsAg positive rate was 7.5% with anti-HBs as 44.5 %, and anti-HBc as 47.8%. The positive rates of HBsAg and anti-HBc among 0-19 year-olds were lower than those of > or = 20 year-olds. (2) The positive rates of HBsAg, anti-HBc and HBV infection among HBV vaccine immunized group were 2.8%, 12.0% and 12.5% respectively, comparing with which among the un-immunized group as 10.2%, 69.8% and 71.2% respectively. (3) The HBsAg positive rate of male was higher than the female's but with no significant difference of anti-HBs and anti-HBc between different sexes. (4) The average HBsAg positive rate of 0-19 years old group was only 2.4%, while that of 20-30 years old group was 13.6%-17.7% and dropped from 60 years old group and on. The anti-HBs positive rate of 0-19 years old people started to drop significantly by age. The anti-HBs and anti-HBc positive rates of > or = 20 years people were showing a rising trend by ages.
CONCLUSIONIt seemed obviously that the HBV epidemiological patterns had changed after HBV vaccine had been universally used for long time in newborns. The age peak of infection had been pushed backward for nearly 20 years. It had been proved that the HBV vaccine immunization program had obtained excellent efficacy.

OBJECTIVETo evaluate the efficacy and safety of oxymatrine in the treatment of chronic hepatitis B.
METHODSA multicenter randomized double-blind placebo-controlled trial was conducted. A total of 144 patients with chronic hepatitis B entered the study for 52 weeks; of them 72 received oxymatrine, and 72 received a placebo. Before and after the treatment, clinical symptoms, liver function, serum hepatitis B virus markers, and adverse drug reactions were observed.
RESULTSIn 144 patients, 14 were dropped and excluded due to inconsistencies in the included standard. Therefore, the efficacy and safety of 130 patients were analyzed. After being treated for 52 weeks, 70.77% of the patients in the study group had a normal ALT level, and in 43.08% and 33.33% their HBV DNA and HBeAg became negative. In the placebo group, 39.68% had normal ALT level, and 12.31% and 3.33% had their HBV DNA and HBeAg become negative. The rates of complete response and partial response in the oxymatrine group were 23.08% and 58.46%, and in the placebo group they were 3.08% and 44.62%. They were significantly higher in the oxymatrine group than in the placebo group. In the oxymatrine treated patients, 12 weeks after its withdrawal, 60.00% had a normal ALT level, 41.54% and 23.33% had both HBV DNA and HBeAg negative. In the placebo group, 31.75% had a normal ALT level, 3.08% and 1.67% had both HBV DNA and HBeAg negative. The rates of complete response and partial response in the oxymatrine group were 21.54% and 47.69%, and in the placebo group they were 0 and 41.54%. They were significantly higher in the study group than in the placebo group. The adverse reaction rates of oxymatrine in the study and the placebo group were 7.69% and 6.15%, respectively, but there was no statistical significant difference between them.
CONCLUSIONOxymatrine is an effective and safe agent for the treatment of chronic hepatitis B.

OBJECTIVETo study the epidemic pattern and trend of HBV infection in the area where the people had been immunized by HBV vaccine for 20 years.
METHODSThe whole sampling method was applied in combination with cross-sectional investigation. Blood samples were taken from every member of families. Markers of HBV infection were determined by using solid-phase radioimmunoassay (SPRIA).
RESULTS(1) The average HBsAg positive rate was 7.5%. The positive rate of markers for HBV infection of 0-19 years old subjects were lower than those of > or = 20 years old subjects. (2) The positive rate of HBsAg of 0-19 years old subjects in 1985 was higher than that in 2005. The anti-HBs positive rate in 1985 stemmed to be higher with age. It was 12.4% in 1- age group to 53.8% in >60 years age group. While the result of 2005 showed that the anti-HBs positive rate of 0-19 years old subjects dropped with age. The anti-HBc positive rate in 1985 also tended to be higher with age. But the result of 2005 showed that the rate of 0-19 years old subjects was just 1.4% to 16.8%.
CONCLUSIONThe epidemic patterns of HBV infection have had significant variations in the target population. HBV vaccine immunization has obtained excellent efficacy.

This study was aimed to assess the effect of Astragalus Polysaccharide (ASPS) on in-vitro hematopoiesis. CFU-GM assays were used to determine the effect of ASPS and thrombopoietin (TPO) on granulocytic-monocyte progenitor cells. The CFU assays were also used to investigate the effect of ASPS on the proliferation of HL-60 cells.HL-60 cells were cultured with serum-free RPMI 1640 medium and treated with or without of different concentrations of ASPS. After 72 h incubation, the number of cells were counted.In addition, the caspase-3 and JC-1 expression was determined by flow cytometry with Annexin V/PI double staining. The results showed that ASPS (100, 200 µg/ml) and TPO (100 ng/ml) significantly promoted CFU-GM formation in vitro. Various concentrations of ASPS and TPO also promoted the colony formation of HL-60 cells, the largest effect of ASPS was observed at a concentration of 100 µg/ml. There were no synergistic effects between TPO and ASPS on cellular proliferation. The results also showed that ASPS significantly protected HL-60 cells from apoptosis in condition of serum-free medium culture, suppressed caspase 3 activation, and reduced the cell apoptosis. It is concluded that ASPS can significantly promote the formation of bone marrow CFU-GM and the proliferation of HL-60 cells, the optimal concentration of ASPS is at 100 µg/ml. In the absence of serum inducing apoptosis, ASPS also significantly reduced the apoptosis of HL-60 cells via suppressing the activation of caspase-3.

In the outbreak of COVID-19,triage procedures based on epidemiology were implemented in a local hospital in Changsha to control the transmission of SARS-CoV-2 and avoid healthcare-associated infection.This re-trospective study analyzed the data collected during the triage period and found that COVID-19 patients were en-riched 7 folds into the Section A designated for patients with obvious epidemiological history.On the other side,nearly triple amounts of visits were received at the Section B for patients without obvious epidemiological history.8 COVID-19 cases were spotted out of 247 suspected patients.More than 50%of the suspected patients were submi-tted to multiple rounds of nucleic acid analysis for SARS-CoV-2 infection.Of the 239 patients who were diagnosed as negative of the virus infection,188 were successfully revisited and none was reported as COVID-19 case.Of the 8 COVID-19 patients,3 were confirmed only after multiple rounds of nucleic acid analysis.Besides comorbidities,delayed sharing of epidemiological history added complexity to the diagnosis in practice.The triaging experience and strategy will be helpful for the control of infectious diseases in the future.

OBJECTIVES:
To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.
METHODS:
A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.
RESULTS:
Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).
CONCLUSIONS
There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ2=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.
