Objective:To investigate the current status of hospitalized neonatal death of different gestational ages in Shaanxi Province.Methods:All neonatal deaths in six hospitals in Shaanxi Province from 2016 to 2020 were retrospectively analyzed, and the differences in perinatal complications, the causes of death, and the age at death were compared using Chi-square (or Fisher's exact ) test. Results:(1) Totally, 220 488 neonates were delivered in the obstetric department of the six hospitals during the study period; 71 782 out of them were admitted to the neonatal department. While 424 neonatal death was reported, giving the total hospitalized neonates mortality rate of 5.5‰ (394/71 782), which included 152 deaths of transferred patients ( n=9 103, 16.7‰), 226 premature (53.3%), 196 term (46.2%), and two post-term infants (0.5%). (2) Among mothers of dead neonates, 73.6% were found to have at least one perinatal complication. The most common one was fetal distress (146 cases, 34.4%), followed by gestational diabetes mellitus (113 cases, 26.7%), amniotic fluid abnormalities ( n=73, 17.2%), maternal infectious diseases ( n=71, 16.8%), and hypertensive disorders in pregnancy (HDP) ( n=52, 12.3%). The lower the gestational age, the higher the proportion of multiple pregnancies and assisted reproduction technology applied (Fisher exact test, P<0.05). On the contrary, the higher the gestational age, the higher the cesarean section rate ( χ 2=26.69, P<0.001). HDP was more likely to occur in the gestational age of 28-31 +6 and 32-34 +6 weeks ( χ 2=37.16, P<0.001), and amniotic fluid abnormalities were more likely to occur in those over 37 weeks ( χ 2=27.47, P<0.001). (3) The five leading causes of neonatal death were neonatal respiratory distress syndrome (NRDS, n=100, 23.6%), neonatal asphyxia ( n=88, 20.8%), maternal infectious diseases ( n=80, 18.9%), and birth defects ( n=54, 12.7%), and pulmonary hemorrhage ( n=22, 5.2%). The first three causes of death in term and post-term infants were neonatal asphyxia ( n=65, 32.8%), birth defects ( n=42, 21.2%), and infectious diseases ( n=26, 13.1%). NRDS ( n=83, 36.7%), infectious diseases ( n=54, 23.9%), and neonatal asphyxia ( n=23, 10.2%) were the three leading causes of death of premature babies. (4) Out of the 326 (76.9%) neonatal deaths within seven days after birth, 162 (38.2%) died within 24 h after birth and 164 cases (38.7%) between one to seven days after birth. Conclusions:Most neonatal deaths occurred among preterm ones and within seven days after birth, whose mothers suffered perinatal complications. The causes of neonatal death vary among different gestational age groups.

Objective:To explore the medication rules of Professor Wang Pei in the treatment of colon cancer.Methods:The medical records of Professor Wang Pei's outpatient treatment for colon cancer were collected, entered into the Traditional Chinese Medicine Inheritance Computing Platform V3.0, and the laws of the prescription's nature, flavor, meridian, drug frequency, drug combination, association rules, and cluster analysis were explored.Results:A total of 65 prescriptions were collected, including 150 Chinese materia medica. The medicinal properties of these Chinese materia medica are mainly warm, cold and flat, the tastes were mainly sweet, bitter and pungent, and the meridians were mainly liver, spleen and kidney meridians. Dampness category and blood circulation promoting and blood stasis category were mainly used, and the most frequently used drugs include Poria, Polyporus, Scutellariae Barbatae Herba, Astragali Radix, Curcumae Rhizoma, and the pairs of Polyporus- Poria, Astragali Radix- Astragali Radix Praeparata cum Melle, Scutellariae Barbatae Herba- Curcumae Rhizoma. Twenty nine high-related drug pairs were obtained from association rules, including Polyporus- Astragali Radix Praeparata cum Melle- Astragali Radix, Poria- Scutellariae Barbatae Herba- Polyporus, Scutellariae Barbatae Herba- Curcumae Rhizoma- Polyporus. The cluster analysis showed the combination of 6 types of medicines mainly focuses on strengthening the spleen and removing dampness, nourishing qi and promoting blood, clearing heat and detoxifying, and astringing the intestines to stop bleeding. Conclusion:Professor Wang Pei mostly discusses the treatment of colon cancer from "spleen dampness, rectification deficiency, heat toxin, blood stasis, bleeding", and the treatment is "invigorating the spleen and removing dampness, invigorating Qi and strengthening the body, clearing away heat and detoxifying, promoting blood circulation and removing blood stasis, and astringent intestines to stop bleeding", which is in line with the thought of Traditional Chinese Medicine treatment of tumors, strengthening the righteousness and eliminating pathogenic factors, and and can be used for clinical reference.

Dyslipidemia is an important risk factor of atherosclerotic cardiovascular disease (ASCVD). Statins delay the occurrence and development of ASCVD, and reduce the risk of cardiovascular events and death. Due to safety concerns, there exist insufficient use of lipid-lowering agents and a high withdrawal rate of the agents in the elderly. To promote the prevention and treatment of ASCVD, this expert consensus is issued and focuses on the management of dyslipidemia of Chinese elderly basing on the clinical evidence of the use of lipid-lowering drugs by the elderly, and the lipid management guidelines and expert consensus recommendations at home and abroad.

Objective:The surveillance results of brucellosis in Lushan County, Pingdingshan City, Henan Province are analyzed to provide basis for formulating prevention and control strategies.Methods:Retrospective analysis method was used to collect the surveillance data from Lushan County Center for Disease Control and Prevention and Animal Husbandry Department from 2011 to 2019. Descriptive statistical analysis was made on the serological, pathogenic of brucellosis.Results:From 2011 to 2019, 15 943 high-risk people were investigated, and 10 834 were serologically tested, with a positive detection rate of 23.11% (2 504/10 834). Among them, the positive detection rate of brucellosis serum increased rapidly in 2013 and decreased after 2016. The positive detection rate was 25.87% (1 593/6 157) in men and 19.48% (911/4 677) in women. The age of positive detection was mainly 40-< 70 years old, accounting for 70.45% (1 764/2 504). The positive detection rate of farmers in all occupations was the highest, which was 25.97% (2 242/8 634). There were significant differences in the positive detection rates among different gender, age and occupation (χ 2=61.163, 27.855, 257.412, P < 0.01). A total of 578 blood samples from patients with acute brucellosis were isolated and cultured, 215 strains of Brucella were detected, and the positive detection rate was 37.20%. Conclusions:The high-risk group of human brucellosis in Lushan County, Pingdingshan City is middle-aged and elderly male farmers engaged in aquaculture. It is suggested that the joint prevention and control measures should be strengthened, the health education of high-risk groups should be strengthened, and comprehensive prevention and control measures should be taken to control the occurrence and prevalence of brucellosis.

Objective: To investigate the efficacy and outcome of transcatheter patent foramen ovale (PFO) closure in patients with cryptogenic stroke (CS). Methods: Sixty consecutive patients with cryptogenic stroke who undertook transcatheter PFO closure between May 2015 and September 2017 in Beijing Tiantan Hospital were enrolled in this prospective study.Transcranial Doppler (TCD) bubble test was performed and right-left shunt(RLS) was confirmed in all patients.Closure success rate,effective closure rate, complications, recurrence of ischemic stroke and new onset atrial fibrillation were evaluated. Results: A total of 60 patients (42 male,age range 24-68 (47±11)years) were included in the study.PFO size (motionless state) was (1.6±0.6)mm.RLS before closure was graded and 11 patients had moderate RLS and 48 patients had large RLS (include 41 patients who experienced shower or curtain effect).Closure success rate was 100% (60/60).No severe complications were observed.At 6 months,45 patients completed TCD bubble test.Of these, 4 patients suffered from moderate to large residual and thus effective closure rate was 91%(41/45).The mean follow-up period was 2-29 (median 12) months. During the follow-up, only 1 patient experienced recurrent cerebral infarction.New onset atrial fibrillation was not detected. Conclusion Transcatheter PFO closure is effective,safe and related with a good outcome in reduction of recurrent CS for patients with PFO.

Objective To investigate the potential prognostic factors in patients with hepatocellular carcinoma (HCC) complicate by portal vein tumor thrombosis (PVTT) who are treated with transcatheter arterial chemoembolization (TACE). Methods The complete clinical data of a total of 46 patients with HCC complicate by PVTT, who were treated with TACE during the period from January 2010 to March 2016, were retrospectively analyzed. Clinical material database was established. Kaplan-Meier test was adopted to analyze the survival rate and the COX risk ratio model was used to screen out the independent prognostic factors. Life table method was employed to calculate the survival time. Results The 6-, 12-, 18- and 24-month survival rates were 51. 2％, 28. 9％, 23. 4％ and 10. 2％, respectively. The median survival time was 6. 7 months. According to mRECIST standard, complete remission (CR) was obtained in one patient (2. 1％), partial remission (PR) in 11 patients (23. 9％), stable disease (SD) in 16 patients (34. 8％) and progress disease (PD) in 18 patients (39. 2％). Multivariate analysis indicated that local tumor response, ascites, cholinesterase, and arteriovenous fistula were the independent factors affecting the prognosis. Conclusion The independent prognostic factors that affect the survival time of HCC patient include local tumor response, ascites, cholinesterase and arteriovenous fistula.

Objective To compare the differentiating effect of Berg Balance Scale (BBS), Mini-Balance Evaluation Systems Test (Mini-BESTest) and Brief-BESTest on the risk of falls in chronic obstructive pulmonary disease (COPD) patients. Methods From September, 2016 to March, 2017, 22 COPD patients with history of falls and other age-matched 66 COPD patients without history of falls were assessed with BBS, Mini-BESTest and Brief-BESTest. The data were compared with paired Logistic regression, Log-likelihood estimate, and the skewness coefficient were calculated. Results BBS, Mini-BESTest and Brief-BESTest all were valuable for differentiating the risk of falls in COPD patients. Log-likelihood estimate value was the least in Brif-BESTest (5.372), followed with Mini-BESTest (12.918) and BBS (17.644). There was not a ceiling effect in Brief-BESTest and Mini-BESTest, but there was in BBS. Conclusion All the BBS, Mini-BESTest and Brief-BESTest can predict the risk of falls in patients with COPD, and Brief-BESTest is the most predictive. There is a ceiling effect in BBS for COPD patients, but not in Brief-BESTest and Mini-BESTest.

Objective For providing experimental platform of chronic graft-versus-host disease (cGVHD),to establish a mouse model by haplo-identical spleen cell infusion.Methods The donor male mice (Balb/cH-2d) and the recipient (Balb/c C57BL/6) F1 H2-d/b (CB6F1) female mice were randomly divided into four groups:3 experimental groups injected with 3 107,6 107 and 9 107 spleen cells,respectively,while the control group received RPMI 1640 solution.H-2d and H-2b were checked to analyze the chimerism in bone marrow cells.Body mass,figure,cutaneous manifestation and survival of recipient mice were observed and scored every 3 days.Pathologic changes of target organs were observed and scored.Results Injection of 6 107 and 6 107 splenocytes in the recipient mice resulted in a chronic disease with a low level of parental cell engraftment steadily.As compared with 3 107 group,the incidence of cGVHD in 6 107 and 9 107 groups were significantly increased (P ＜0.01).But there was no significant difference between 6 107 and 9 107 groups (P＞0.05).Conclusion A murine model of cGVHD after haplo-identical spleen cell infusion of donor is successfully established by injection of 6 107 and 9 107 spleen cells.

Objective To evaluate the value of PET-CT in patients with breast cancer and to determine if the PET-CT can provide additional information to predict early response to neoadjuvant chemotherapy (NAC).Methods NAC was given to 20 patients with breast cancer confirmed by biopsy puncture from September 2009 to March 2012.The PET-CT was carried out for all patients before NAC.TEC program with three weeks for one cycle was selected.After 6 days of the first cycle,the PET-CT was performed again.The changes of standard uptake value before and after the first cycle were compared.At the same time hand palpation was selected to detect the changes in tumor size before and after the first cycle of NAC.The changes of the standard uptake value and in tumor size need to refer to the pathology Miller & Payne classification methods to evaluate the efficacy of the NAC.Results The SUV were (7.51±1.76) Bq/ml and (4.98±1.61) Bq/ml before and after chemotherapy (t =7.916,P ＜ 0.05) the maximum tumor diameters were (9.62±4.38) cm and (8.89±4.08) cm before and after NAC (t =2.154,P＞ 0.05).SUV had highly correlated with pathological MP classification (r =0.725,P =0.000); while for the tumor size there was no significant change (r =0.026,P =0.824).Conclusion PET-CT can predict the efficacy earlier and is more accurate than clinical efficacy standard for the NAC.

OBJECTIVETo analyze the five-year effectiveness of the people living with HIV/AIDS who initially received highly active antiretroviral therapy (HAART) in Jiangsu province.

METHODSHIV/AIDS initially received HAART from 1 Jan 2005 to 31 May 2014 in Jiangsu province with the CD4(+)T cell count tested in baseline, 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after treatment initiation were selected. According to their retrospectively collected baseline and follow-up data, statistical analysis was performed using SPSS 16.0 software to analyze the variation of CD4(+)T counts and its impact factors in different times after treatment initiation.

RESULTSA total of 200 patients were included. A total of 134 patients were men, and 66 were women, the ratio of male to female was 2.03: 1; mean age was (39.7 ± 10.3) years old; 69.0% (138/200) of the patients married; 53.0% (106/200) as the most were infected with HIV through heterosexual transmission, and followed by men who have sex with men (MSM) (25.5%, 51/200); taken together as 78.5% (157/200).58.5% (117/200) were treated in the CDC. The mean (95%CI) baseline CD4(+)T cell count of cases was 106.9 (93.3-120.5) cells/µl; the CD4(+)T count tested in 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after treatment initiation were 107.3, 152.9, 221.6, 260.0, 281.3 and 316.4 cells/µl more than baseline respectively; the CD4(+)T count after treatment initiation has increased over time (F = 201.06, P < 0.01) . The mean(95%CI) CD4(+)T count tested in 5 years after treatment initiation can increase to 540.7(445.4-635.9) cells/µl with a baseline CD4(+)T count more than 200 cells/µl, but in the subgroups with a baseline CD4(+)T count less than or equal to 50 cells/µl, 51-100 cells/µl, 101-150 cells/µl and 151-200 cells/µl, it only can reach to 431.4 (375.9-487.0), 400.0 (339.9-460.2), 380.3 (330.6-430.0) and 412.1 (369.3-454.8) cells/µl respectively. The mean (95%CI) CD4(+)T count tested in 5 years after treatment initiation with 1 baseline symptom categories can increase to 449.2 (392.2-506.2) cells/µl, while 409.1(317.8-500.5)cells/µl in the subgroup with baseline symptom categories more than or equal to 2. The CD4(+)T after treatment increased slowly associated with a lower baseline CD4(+)T count level and more baseline symptom categories (F values were 3.96 and 2.35, P < 0.01).

CONCLUSIONIt has a remarkable effectiveness for HIV/AIDS treatment in Jiangsu province. The patients with a baseline CD4(+)T count more than 200 counts/µl have a better immune function recovery.
