ABSTRACT
ObjectiveTo analyze the effects of different feeding patterns on the physical and nutritional status of children aged 6‒12 months， so as to provide reference for promoting scientific feeding and health development of infants and young children. MethodsChildren born between December 2019 and February 2020 and who had completed three follow-up visits at 6‒， 9‒ （8‒10 months） and 12‒ （11‒14 months） months old in all of the 13 communities of Minhang， Shanghai were selected. The subjects’ basic information was investigated by questionnaires. The indicators including feeding pattern， physical development （body weight， body length， head circumference） and nutritional status （the detection rate of overweight， obesity， low body weight， growth retardation， emaciation and iron deficiency anemia） were followed up in the outpatient department， with iron deficiency anemia only monitored at the 6‒ and 12‒ months old. According to different feeding patterns， the groups of 6‒ months old were divided into three groups of exclusive breast feeding （EBF）， mixed feeding （MF） and artificial feeding （AF）， while 9‒ and 12‒ months old were divided into MF and AF groups. The differences of basic information and follow-up results among the groups were analyzed. ResultsA total of 470 children were included， including 130 （27.66%）， 288 （61.28%） and 52 （11.06%） respectively in EBF， MF and AF groups at the 6‒ months old，and 319 （67.87%） and 196 （41.70%） in MF group at the 9‒ and 12‒ months old. There was no significant difference in the other follow-up results among the groups. The detection rate of iron deficiency anemia in 6‒ months old EBF （13.08%） was higher than that in MF group （5.90%） and AF group （1.92%） （χ2=8.40， P=0.010）， while it was still higher in 12‒ months old MF group （9.69%） than in AF group （2.92%） （χ2=9.68， P=0.002）. ConclusionThere is no significant difference in body weight，body length， head circumference， and the detection rates of overweight， obesity， low body weight， growth retardation and emaciation among the groups of different feeding patterns in the children aged 6‒12 months. The detection rate of iron deficiency anemia in the EBF and MF groups is significantly higher than that in the AF groups of children aged 6‒ and 12‒ months old.
ABSTRACT
Objective:To investigate the Chinese anesthesiologist′s proficiency, training experience and needs of flexible bronchoscope-guided awake flexible bronchoscopy intubation (AFBI) using a questionnaire method.Methods:The cluster sampling was used, and self-designed questionnaires that addressed 54 questions in 5 categories were distributed through WeChat and online platforms. The survey took one month, and the answers were automatically recorded by the WeChat server.Results:A total of 1 250 anesthesiologists participated in the survey in 30 provinces of China, 9 of them were not anesthesiologists, and 1 241 (99.28%) questionnaires were validated. In the valid questionnaires, 52.70% (654) of the anesthesiologists were from tertiary hospitals, and 74.78% (928) of the anesthesiologists were attending physicians or above, only 7.57% (94) of the anesthesiologists had sufficient confidence in AFBI. Twenty-five point two two percent (313) of the anesthesiologists preferred fiberoptic intubation as the first tool when dealing with the anticipated difficult airway. Forty-eight point one one percent (597) of the anesthesiologists had implemented AFBI. Among them, 80.74% (482) had experienced unsuccessful AFBI practices. Eight hundred and ninety-four anesthesiologists had received AFBI training, and the most common AFBI training strategy was theoretical lectures. In addition, the degree of satisfaction regarding the theoretical lectures quality, technical training, clinical practice relativity and non-technical skills training was 21.47% (192), 14.32% (128), 12.3% (110) and 17.90% (160), respectively. The degree of satisfaction with all the 4 training elements mentioned above was 7.27% (65).Conclusions:The awareness and practice of Chinese anesthesiologists in terms of clinical application of AFBI to treat difficult airways need to be strengthened at present, and the lack of high-quality AFBI training may be the key.
ABSTRACT
Objective:To identify problems and demands for antenatal care (ANC) among pregnant women in different trimesters of pregnancy in Shanghai for optimizing ANC service during the epidemic of COVID-19.Method:s Organized by maternal and child health care institute in the 16 districts of Shanghai, a cross sectional study was conducted among pregnant women who came to pregnancy registration in the community health centers or attended ANC in midwifery hospitals from February 7 to February 12, 2020. Consented participating women completed a semi-structured online questionnaire voluntarily. Data was analyzed using frequency,chi-square test and scoring.Result:s A total of 2 002 valid questionnaires were collected from 183 community health centers and 67 midwifery hospitals. About 94.6%(1 894/2 002) of the pregnant women worried about being infected during the COVID-19 epidemic, and 14.7% (294/2 002) demanded for psychological consultation. Time-lapse appointments for ANC were requested by 87.7% (1 756/2 002) of the participants for avoiding presenting themselves in people-density places. Compared with other pregnancy trimesters, pregnant women in the second trimester were more willing to reduce the frequency of ANC (35.2% versus 39.5% versus 48.1%, P<0.01). Compared with multiparas, primiparas were more willing to have online consultation and guidance (49.2% versus 63.8%, P<0.01). Regarding the needs for health knowledge on COVID-19, personal protection against 2019 novel coronavirus (2019-nCoV) was the most concerned for pregnant women, and 71.0% (1 421/2 002) of them preferred to obtain knowledge through health applications, official Weibo and WeChat. Conclusions:Pregnant women in Shanghai critically concern about the risk of 2019-nCoV infections, and highly demand knowledge and measures on prevention and protection from COVID-19. They ask for having time-lapse appointments for ANC and online access to health information and services. Maternal and child care institutes should understand the demands of pregnant women, optimize the means of ANC service, and provide tailored and accessible health education and service for the safety of mother and child.

Objective To identify risk factors for local recurrence and distant metastasis in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU).Methods We retrospectively reviewed 269 patients with UTUC who had performed RNU from 2003 to 2013 in the Affiliated Hospital of Qingdao University.158 were males and 111 were females,aged range from 37 to 86 years old,left side were 144 cases and right side were 125 cases,157 cases occurred in renal pelvis and 112 cases in ureter,the diameter of tumor ＞ 3 cm were 163 cases,≥ pT3 stage were 143 cases,presence of lymphovascular invasion (LVI) were 35 cases,high grade tumors (G3) were 185 cases,presence of hydronephrosis were 185 cases,multifocal tumors were 28 cases,sessile tumors were 86 cases,neutrophil to lymphocyte ratio(NLR) ≥ 2.0 were 109 cases,estimated glomerular filtration rate (eGFR) ＜ 60ml/(min · 1.73 m2) were 62 cases,plasma fibrinogen ≥3.2 g/L were 129 cases.Univariate and multivariate analyses were performed to identify independent prognostic factors for local recurrence-free survival (IRFS) and distant metastasis-free survival (dMFS).Results The median follow-up was 43.8 months (range 4.4-131.8).30 patients had a local recurrence with a median intermittent period of 19.4 months (range 4.3-71.3).35 patients had a distant metastasis with a median intermittent period of 17.7 months (range 4.1-51.4).In univariate analysis,sessile tumor(P =0.041),tumor multifocality (P =0.027),location in ureter (P =0.001),presence of LVI (P＜0.001),≥pT3 stage(P ＜0.001),eGFR ＜60ml/(min · 1.73 m2) (P =0.009) and plasma fibrinogen ≥ 3.2 g/L (P ＜ 0.001) were associated with lRFS.While high-grade tumor (G3) (P =0.012),sessile tumor (P ＜ 0.001),presence of LVI (P ＜ 0.001),presence of hydronephrosis (P =0.046),and NLR ≥2.0 (P =0.002) were associated with dMFS.Multivariate analysis revealed that location in ureter(HR =4.835,95 ％ CI 1.792-13.044,P =0.002),presence of LVI (HR =5.037,95 ％ CI 2.183-11.230,P ＜ 0.001),≥pT3 stage(HR =2.987,95％ CI 1.078-8.283,P =0.035) and plasma fibrinogen ≥3.20g/L (HR =4.281,95 ％ CI 1.454-12.603,P =0.008) were independent factors for lRFS.Sessile tumor (HR =6.097,95％ CI 2.536-14.660,P ＜ 0.001),presence of LVI (HR =4.191,95％ CI 2.035-8.633,P ＜ 0.001),and NLR ≥2.0 (HR =2.741,95％ CI 1.128-6.657,P =0.026) were independent factors for dMFS.We stratified patients into three risk groups of LR and DM based on the results of the multivariate analysis respectively.The 1-year,3-year,5-year lRFS rates were 99.0％,96.8％,95.0％ in the low-risk group;94.5％,91.2％,87.6％ in the intermediate-risk group;and 77.8％,58.8％,58.8％ in the high-risk group.The differences among groups were significant (P ＜ 0.001).The 1-year,3-year,5-year dMFS rates were 98.4％,97.6％,96.0％ in the low-risk group,88.0％,73.8％,71.8％ in the intermediate-risk group,and 63.7％,42.9％,28.5％ in the high-risk group.The differences among groups were significant as well(P ＜ 0.001).Conclusion Location in ureter,presence of LVI,≥ pT3 stageand plasma fibrinogen ≥3.2 g/L were independent factors for lRFS.Sessile tumor,presence of LVI,and NLR ≥ 2.0 were independent factors for dMFS.The risk stratification models may be useful for identifying the patients with high risk of LR/DM after surgery.
ABSTRACT
Objective To evaluate the effect of desflurane on emergency in patients undergoing suspension microlaryngoscopy surgery.Methods Forty adult patients with ASA Ⅰ-Ⅱ who underwent elective microlaryngoscopy surgery were randomly divided into desflurane group (group D,n =20) and sevoflurane group (group S,n =20).Time from end of the surgery to resume of spontaneous breathing,extubation,and discharge from postanesthesia care unit (PACU) were recorded.The extent of cough reflex during extubation and cough episode after extubation were recorded.Perioperative mean arterial pressure (MAP) and heart rate (HR) were recorded before anesthesia induction (T0),on suspension laryngoscope instrument (Ttary),the gas concentration reached 1.3 MAC (T1.3mac),1 min after 1.3 MAC (T1.3 1),on arrival at PACU (Tpacu),on extubation (Textu),1 min after extubation (T 1),5 min after extubation (T 5),and on discharge from PACU (Tdis).Results Time from end of the surgery to resume of spontaneous breathing was not significantly different between the two groups.Time to extubation in group D was 4.6 min,which was shorter than it was in group S (P＜0.05).Time to discharge from PACU was 5.0 min in group D,which was shorter than it was in group S (P＜0.05).Incidence of cough was 100％ in group D and 55％ in group S during extubation (P＜0.05).The episode of coughing after extubation was not significantly different between the two groups.Perioperatively,changes of MAP and HR between the two groups were not significantly different (P ＞ 0.05).Conclusions Desflurane for adult patients undergoing suspension microlaryngoscopy surgery was associated with fast emergence.The incidence of cough was higher in group D than it was in group S during extubation,but it continued a short duration.
ABSTRACT
Objective To investigate the apoptosis of gastric carcinoma SGC-7901 cell induced by histone deacetylase inhibitor(TSA)and to clarify its mechanisms.Methods The apoptosis-inducing role of TSA on gastric carcinoma SGC-7901 cell was investigated with the help of cell proliferation assay,Annexin V stain,cell flow analyzer and Tunel assay.Western blot,gene chips,real time PCR were employed to study the influence and mechanisms of TSA on the expression of gastric carcinoma cell SGC-7901 p53,bax,etc.Results TSA could induce the apoptosis of gastric carcinoma SGC-7901 cells,increase the expression of p53 and bax,and decrease the expression of bcl-2.survivin and easpase in gastric carcinoma SGC-7901 cells.TSA could transfer AIF and EndoG from mitochondria to nucleus.The apoptosis induced by TSA was brought about through the regulation of multiple apoptosis-related genes,and the apoptosis pathway induced by TSA was caspase-independent.Conclusion TSA can induce caspase-independent apoptosis in gastric carcinoma SGC-7901 cell through the regulation of multiple apoptosis-related genes.
ABSTRACT
Oblective To define the median effective dose (ED50) and 95%effective dose of fentanyl for inhibition of emergence agitation after sevoflurane-remifentanil anesthesia in children.Methods Twenty six ASA ⅠorⅡchildren aged 5-8 yr weighing 15-30 kg undergoing adenoidectomy under general anesthesia were studied.The patients were unpremedicated.Anesthesia was induced with inhalation of 8%sevoflurane (fresh gas flow=6 L/min)and iv remifentanil 1μg/kg.The patients were mechanically ventilated after tracheal intubation.Fentanyl was injected iv to inhibit emergence agitation.The dose of fentanyl was determined by using modified Dixon's upand-down method (increment or decrement of 0.5μg/kg).The initial dose of fentanyl was 4 μg/kg.Anesthesia Sevoflurane inhalation and remifentanil infusion were terminated at the end of operation.The patients were transferred to the PACU.No alteration in the ventilatory settings was made.Stimulation of the patients was avoided during emergence.The emergence time and the occurrence of agitation,nausea and vomiting and respiratory depression within 4h after operation were recorded.ED50,ED95 and 95%confidence interval (CI) of fentanyl for inhibition of emergence agitation were calculated.Results ED50 was 3.01μg/kg (95%CI 2.52-3.40μg/kg) and ED95 3.81μg/kg(95%CI 3.41-6.22μg/kg).No nsusea and vomiting and respiratory depression occurred within 4h after operation.The emergence time was (11.3±2.6) min.Conclusion The ED50 and ED95 of fentanyl for inhibition of emergence agitation after sevoflurane-remifentanyl anesthesia were 3.01 and 3.81μg/kg respectively in children.
ABSTRACT
Objective To study the changes in the immune function of advanced hepatic carcinoma patients after thermochemoembo-lization via hepatic artery. Methods Forty advanced hepatic carcinoma patients were randomized divided into 2 groups. A group (n=20) was treated by perfusion with ADM(40mg) + MMC(10mg) in 37℃ 9% sodium chloride solution via hepatic artery, and B group (n=20) was treated by perfusion with ADM(40mg) + MMC(10mg) in 60℃ 9% sodium chloride solution via hepatic artery, then all were embolized with some quantity of lipiodol. Flow cytometry (FCM) was used to detect the changes in percentages of T-lymphocyte subsets (CD3<'3, CD4<'+, CD8<'+) and NK cells, and the contents of soluble interleukin-2 receptor (sIL-2R) were detected by double sandwich ELISA before and after therapy. LDH enzyme-release assay was used to detect cytotoxic activity of NK cells. Results Compared with pre-therapy group or A group after therapy, the percentage of CD4<'+ cells of B group after therapy significantly increased (P<0.05), the percentages of CD8<'+ cells and the content of sIL-2R of B group after therapy markedly decreased (P<0.05). The percentages of NK cells and cytotoxic activity NK cells of B group after therapy were significantly higher than those from pre-therapy group or A group (P<0.05). Conclusion Intra-arterial thermochemoembolization may activate and improve cell-mediated immune function with a certain degree.
ABSTRACT
Objeetive To explore the differentiation of B lymphocytes and expression of B7-related protein-1 (B7RP-1)on B lymphocytes in patients with systemic lupus erythematosus(SLE).Methods Three-color immunofluorescent staining and flow cytometric assay were used to analyze the frequency of three types of B lymphocytes,I.e.,plasma cells,memory B lyphocytes and naive B lymphocytes,as well as the expression of B7RP-1 on these cells in peripheral blood from 23 patients with SLE and 16 normal human controls.Clinical data of these patients with SLE were collected.and SLE disease activi index(SLEDAI)was also evaluated.The relationship was assessed between the expression of B7RP-1 and SLEDAI.Results The frequency of plasma cells was highest in patients with active SLE.followed by patients with inactive SLE and normal human controls(P＜0.01).A significant decrease was observed in the frequency of memory B lymphocytes in patients with active SLE compared with normal controls (P＜0.01),but no significant difference was found between patients with inactive SLE and those with active SLE(P＞0.05).Regarding the frequency of naive B lymphocytes,there was no significant difierence among the three groups.Increased frequency of plasma cells was also noted in patients with lupus nephritis(LN)compared with those without LN [(6.15±3.12)%vs(3.31±1.41)%,P＜0.05 ],but no significant difierence was found with regard to the frequency of memory or naive B lymphocytes between these two groups.The expression rate Of B7RP-1 was significantly lower on total lymphocytes from patients with SLE than from normal human controls (46.51%vs 63.75%,P＜0.05),which was the case with B7RP-1 on plasma cells,memory B lyphocytes and naive B lymphocytes (all P＜0.01),whereas no significant difierence was found between patients with inactive SLE and active SLE or between patients with and without LN.In addition.no correlation was found between the expression of B7RP-1 and SLEDAI(r=0.035,P＞0.05).Conclusions In peripheral blood of patients with SLE,the frequency of plasma cells is increased,while the expression of B7RP-1 on lymphocytes is decreased,which may be relevant to the pathogenesis of SLE.

ABSTRACT
AIM: To compare the impacts of adriamycin(ADM) intermittent and continuous heat infusion on respiration, heart rate and temperature of the rabbit as well as the concentration of ADM in VX-2 tumor for the verification of the safety and effectiveness of intermittent heat infusion through VX-2 transplanted tumor model in rabbit liver.METHODS: VX-2 tumor models were established respectively in the thighs of 30 New Zealand rabbits. All 30 rabbits were randomly allocated into three groups with 10 rabbits each. After catheterizing into femoral artery, which was demonstrated as the supply artery of tumors by digital subtraction angiography(DSA), animals in three groups were infused with 100 mL saline at normal temperature and ADM, 100 mL saline at 60 ℃ and ADM continuously and 100 mL saline at 60 ℃ and ADM intermittently respectively. During infusion, the 43 ℃ to 45 ℃ lasting time in the tumor tissues of the two 60 ℃ groups was measured. After infusion, the respiration(time/minute), heart rate(beats/minute) and temperature(℃ )of the rabbits in each group as well as the concentrations of ADM in tumor tissue were measured immediately.RESULTS: The concentration of ADM was (7. 1 ± 2.2) mg/L in normal temperature infusion group, (17.2 ± 1.6) mg/L in 60 ℃ continuous infusion group and(16.5 ±3.4) in 60 ℃ intermittent infusion group. There were significant differences among three groups( F = 48.95, P = 0. 000), but there was no significant difference between 60 ℃ intermittent infusion group and 60 ℃ continuous infusion group( P ＞ 0. 05). 43℃ to 45 ℃ lasting time was(22.5 ±1.4) minutes in 60 ℃continuous infusion and (24.3±2.4)minutes in 60 ℃intermittent infusion group( F =4.20, P ＞ 0.05) . There were significant differences among three groups in respiration, heart rate and temperature( F = 14. 58, 33.07, 10.00, P ＜ 0.01), but there was no significant difference in the respiration, heart rate and temperature between 60℃ intermittent infusion and normal temperature infusion group ( P ＞ 0. 05).CONCLUSION: Intermittent thermochemotherapy is a more effective and safe interventional thermochemotherapy method compared with continuous heat infusion.

ABSTRACT
Objective To investigate the effect of competitive N-methyl-D-aspartate (NMDA) receptor antagonist LY274614 [(?)-6-phosphonomethyl-decahydroisoquinolin-3-carboxylic acid] on the development of morphine tolerance and dependence.Methods Male Spraque-Dawley rats were rendered tolerant and dependent by subcutaneous injection of morphine(15mg/kg body weight) three times a day for 10 consecutive days. LY274614 (2, 4, 6 mg/kg body weight) was also given subcutaneously by subcutaneous injection. Antinociception was measured by tail-flick (TF) test. Tail was exposed to the heat source(a beam of high intensity light). The time from the beginning of exposure to removal of tail from the path of the heat source was taken as latency. The baseline TF latency without medication was 4-5 seconds. A ten-second maximum exposure to the heat source was used to minimize damage to tissue during the multiple measurements. Morphine prolonged TF latency. With the development of tolerance TF latency gradually returned to baseline value. Physical dependence on morphine was assessed by abstinence syndrome precipitated by subcutaneous injecting naloxone 10 mg/kg on the tenth day. According to method of Blasig, the number of jumping/30min after naloxone injection was recorded as an index pf abstinence syndrome. Rats were randomly divided into 8 groups (n=6-8). Each group received morphine 15 mg/kg or normal saline (NS) 1.5 ml/kg+LY274614 (2.0,4.0,6.0 mg/kg) or NS, group 1: morphine+NS; group 2: NS+NS; group 3:morphine+LY274614 (2mg/kg); group 4: NS+LY274614 (2mg/kg); group 5: morphine+LY274614 (4mg/kg); group 6: NS+LY274614 (4mg/kg); group 7: morphine+LY274614 (6mg/kg); group 4: NS+LY274614 (6mg/kg).Results LY274614 itself did not have analgesic action, but if used with morphine, it did inhibit the development of tolerance. In group 5 and 7 the decrease in TF latency was more gradual than that in morphine+saline group. 4 and 6 mg/kg LY274614 reduced the number of jumping/30min following naloxone injection.Conclusions LY274614 can inhibit morphine tolerance and dependence rendered by consecutive subcutaneous morphine injection.
