OBJECTIVETo compare the effects on anesthesia recovery between assisted-electroacupuncture fast tracking anesthesia and simple fast tracking anesthesia in patients with minim ally invasive percutaneous nephrolithotomy (mPCNL).

METHODSEighty cases of mPCNL were selected and randomly divided into a treatment group and a control group. Fentanyl (1-2 microg/kg), sevoflurane (8%) and rocuronium (0.5 mg/kg) were applied to perform anesthesia induction in both groups, and endotracheal inhalation of sevoflurane and intravenous pump injection of remifentanil were adopted to main anesthesia status during the operation. 20 min before anesthesia induction, bilateral Neiguan (PC 6), Neimadian, Hegu (LI 4), Yangxi (LI 5), Zhongji (CV 3), Qichong (ST 30), Zuwuli (LR 10) were selected and punctured in the treatment group, and elecctroacupuncture was given after arrival of qi until 30 min after the wake-up from anesthesia and withdrawal of endotracheal tube. The dosage for anesthesia maintenance, recovery time of awareness, extubation time, incidences of nausea, vomiting and chill and irritation of urethral catheters were observed and recorded.

RESULTS(1) The dosages of remifentanil and sevoflurane in the treatment group during the operation were obviously less than those in the control group [remifentanil: (5. 27 +/-1.23) micro g/kg h vs (7.35+/-1.70) micro g/kg . h; sevoflurane: (1.12+/-0.43) vol% vs (2.35+/-0.87) vol% , both P<0. 001]. (2) The recovery time of awareness and extubation time in the treatment group were significantly earlier than those in the control group [recovery time of awareness: (5.65 +/- 2.34) min vs (8. 87 +/- 6. 84) min, P<0. 01; extubation time : (7. 23+/-4. 35) min vs (10. 62+/-8. 16) min, P<0. 05]. (3) The incidences of nausea, vomiting and chill in the treatment group were significantly less than those in the control group (all P<0. 05). (4) The irritation of urethral catheters on urethra in the treatment group was significantly less than that in the control group (P<0. 001).

CONCLUSIONThe assisted-electroacupuncture anesthesia could reduce the dosage of remifentanil and sevoflurane in mPCNL fast tracking anesthesia in urinary surgery, reduce the incidences of nausea, vomiting, chill and irritation of urethral catheters during recovery stage, and prompt recovery of mPCNL patients.

To study the intervention programs on smoking cessation in a general hospital and to evaluate its effects of the programs. Four methods including: a) the intervention through specialists in the smoking cessation clinic, b) short-time intervention in the out-patient department,c) free medical intervention, d) group intervention, were adopted for different smokers, with health counseling, psychological intervention and drug treatment. Intervention effect was evaluated by standard methods. During the 20-month period of the project, we treated 690 cases and 402 completed 6-month follow-up. Preliminary results in 402 cases showed that the three methods of smoking cessation interventions could reduce the amount of cigarette smoking and increase the quitting rate. Motivation to quit smoking, intervention methods and intensity of intervention seemed cessation clinic (31.6%) and in the group intervention (30.9%) was higher than short-time intervention in free medical events (15.1%). The successful rate of smoking cessation depended on the motivation of quitters, and the attitude, methods and intervention skills of the physicians.Therefore, it is necessary to explore and develop smoking cessation service models suitable to national context and individual intervention methods in China.

Objective To study the HIV-1 diversity and how did it promot the rapid spread of AIDS,in Guizhou province.Methods A total of 190 HIV-1 positive subjects were collected in different years and regions from Guizhou province.The env and gag genes were amplified with nested PCR and their sequences were determined.The subtypes were identified by the MEGA 4.0 software and the relationships between subtypes and AIDS epidemic were analyzed.Results The number of HIV/AIDS reported cases was increased from 66 in 1998 up to 8435 in 2009,a 16.38 time increase in 7 years.Subtypes B(9),B'(4),C(2),CRF07_BC(75),CRF08_BC(17),CRF01_AE(64)were identified in Guizhou province among the samples collected in various periods of time.The genetic diversities in env gene of CRF07_BC and CRF08_BC increased along with the spreading of HIV (from 0.035±0.006 to 0.092±0.011).Subtype B'(4/11)appeared the main subtype prevailed in Guizhou in 1998 as well as CRF07_BC(26/41)in 2002 and CRF01_AE(62/119)in 2007.The HIV/AIDS epidemic in Guizhou province showed an rapidly upward trend,with the main risk factors of HIV transmission as 2610 cases through injecting drug users(IDUs).and 176 cases due to sexually transmitted infections(STIs),from year 2001 to 2006.However,STIs began to increase rapidly,after 2006,with 1713 cases of IDUs and 1833 cases of STIs.Data indicated that the change of composition of different HIV-1 subtypes was correlated with the mode of transmission in Guizhou province(x2=41.253,P=0.000).Conclusion The types of HIV strains changed over time as well the turnover of the main risk factors.Sexual transmission,including both hetero-and homo-sexual became the main risk factors,suggesting the development of related prevention and control programs,on HIV/AIDS should be considered accordingly in the future.

This paper collected and introduced the clinical experiences of national TCM master Xuan Guowei in treating pemphigus by stages.Xuan Guowei argued that in the acute stage, the main syndrome was intense heat toxin and mainly treated by resolving toxins and dispelling pathogen.With the development of the disease course, warm-febrile pathogen would change into dryness, burning fluid and consuming qi and thus in the later stage, yin deficiency accompanied with dampness-heat was mostly seen.It should be treated by dispelling dampness and fortifying the spleen, as well as clearing heat and nourishing yin.The disease has a relapsing course and could be easily conversed into the impairment of yin and deficiency of qi.Xuan advocated the combination of Chinese and western medicine for the treatment of pemphigus.On the basis of hormone therapy, the external treatment of Chinese medicine according to different stages of the disease could further be added.

INTRODUCTION: Pregnant women are reported to be at increased risk of severe coronavirus disease 2019 (COVID-19) due to underlying immunosuppression during pregnancy. However, the clinical course of COVID-19 in pregnancy and risk of vertical and horizontal transmission remain relatively unknown. We aim to describe and evaluate outcomes in pregnant women with COVID-19 in Singapore. METHODS: Prospective observational study of 16 pregnant patients admitted for COVID-19 to 4 tertiary hospitals in Singapore. Outcomes included severe disease, pregnancy loss, and vertical and horizontal transmission. RESULTS: Of the 16 patients, 37.5%, 43.8% and 18.7% were infected in the first, second and third trimesters, respectively. Two gravidas aged ≥35 years (12.5%) developed severe pneumonia; one patient (body mass index 32.9kg/m2) required transfer to intensive care. The median duration of acute infection was 19 days; one patient remained reverse transcription polymerase chain reaction (RT-PCR) positive >11 weeks from diagnosis. There were no maternal mortalities. Five pregnancies produced term live-births while 2 spontaneous miscarriages occurred at 11 and 23 weeks. RT-PCR of breast milk and maternal and neonatal samples taken at birth were negative; placenta and cord histology showed non-specific inflammation; and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific immunoglobulins were elevated in paired maternal and umbilical cord blood (n=5). CONCLUSION The majority of COVID-19 infected pregnant women had mild disease and only 2 women with risk factors (obesity, older age) had severe infection; this represents a slightly higher incidence than observed in age-matched non-pregnant women. Among the women who delivered, there was no definitive evidence of mother-to-child transmission via breast milk or placenta.

Background/Aims: Nonalcoholic fatty liver disease (NAFLD) is closely associated with diabetes. The cumulative impact of both diseases synergistically increases risk of adverse events. However, present population analysis is predominantly conducted with reference to non-NAFLD individuals and has not yet examined the impact of prediabetes. Hence, we sought to conduct a retrospective analysis on the impact of diabetic status in NAFLD patients, referencing non-diabetic NAFLD individuals. Methods: Data from the National Health and Nutrition Examination Survey 1999–2018 was used. Hepatic steatosis was defined with United States Fatty Liver Index (US-FLI) and FLI at a cut-off of 30 and 60 respectively, in absence of substantial alcohol use. A multivariate generalized linear model was used for risk ratios of binary outcomes while survival analysis was conducted with Cox regression and Fine Gray model for competing risk. Results: Of 32,234 patients, 28.92% were identified to have NAFLD. 36.04%, 38.32% and 25.63% were non-diabetic, prediabetic and diabetic respectively. Diabetic NAFLD significantly increased risk of cardiovascular disease (CVD), stroke, chronic kidney disease, all-cause and CVD mortality compared to non-diabetic NAFLD. However, prediabetic NAFLD only significantly increased the risk of CVD and did not result in a higher risk of mortality. Conclusions Given the increased risk of adverse outcomes, this study highlights the importance of regular diabetes screening in NAFLD and adoption of prompt lifestyle modifications to reduce disease progression. Facing high cardiovascular burden, prediabetic and diabetic NAFLD individuals can benefit from early cardiovascular referrals to reduce risk of CVD events and mortality.

Objective To evaluate the efficacy of Budesonide/formoterol to control asthma under real-life conditions.Methods A muhi-center, open label, non-interventional study was conducted.Asthma control after 12 week therapy with Budesonide/formoterol was assessed by Asthma Control Questionnaire (ACQ) and modified Asthma Control Questionnaire (ACQ5).Results A total of 360 asthma patients were recruited,including 228 adult patients and 132 child patients.After 12 weeks' therapy,all the patients' medium value of ACQ was decreased significantly from 2.03 (adults 2.20, children 1.74) at baseline to 0.60 (adults 0.78, children 0.29) (P < 0.0001), and the medium value of ACQ5 was also decreased significantly from 2.4 (adults 2.24, children 1.76) at baseline to 0.47 (adults 0.62, children 0.20) (P < 0.0001).Conclusion Budesonide/formoterol is effective in asthma treatment, by which most asthma patients obtain and maintain clineal control.

OBJECTIVETo explore the heterogeneous subclones in acute myeloid leukemia (AML) with t(8;21) by quantitative multicolor- fluorescence in situ hybridization (QM-FISH), and to figure out whether there is putative ancestral relationship among different subclones.

METHODSBacterial artificial chromosomes (BAC) clones that contain the targeted genes including AML1, ETO, WT1, p27 and c-kit were searched in the data base UCSC Genome Bioinformatics. Multicolor FISH probes were prepared by linking fluorescein labeled dUTP or dCTP to targeted genes by nick translation. Bone marrow mononuclear cells from t (8;21) AML patients are dropped on to the wet surface of glass slides after hypotonic treatment and fixation. After hybridization, the fluorescence signals were captured by Zeiss fluorescence microscope. The copy number of AML1, ETO, WT1, p27, c- kit and the AML1-ETO fusion gene in AML1-ETO positive cells was counted. The cells with same signals were defined as a subclone. Various subclones were recorded and their proportions were calculated, and their evolutionary relationship was deduced. The subclones in matched primary and relapsed samples were compared, the evolution of dominant clones were figured out and the genomic abnormality that is associated with relapse and drug resistance were speculated.

RESULTSIn this study, 36 primary AML with t(8;21) cases and 1 relapsed case paired with the primary case were detected. In these 36 primary cases, 4 cases (11.1%) acquired additional AML1-ETO fusion signal, 3(8.3%) had additional AML1 signal, 4(11.1%) had additional ETO signal, 20(55.6%) had additional WT1 signal, 15(41.7%) had additional p27 signal and 14(38.9%) had additional c-kit signal. In addition, 10(27.8%) displayed AML1 signal deletion, and such an aberration represents statistic significance in male patients. It seems that male patients usually accompany AML1 signal deletion. Of 36 cases, 28(77.8 %) harbored at least 2 subclones (ranged from 2 to 10). According to the genetic signature of subclones, we can assemble a putative ancestral tree, and the genetic architecture is linear or branching. In particular, the clonal architecture of the relapsed sample exhibited significant clonal evolution compared to its paired sample at diagnosis, including proportion changes in dominant clone, subclone disappearance and appearance of new dominant clones.

CONCLUSIONGenomic abnormality is very diverse in t(8;21) AML. Subclones have linear or complex branching evolutionary histories, and clonal architecture is dynamic.
