ABSTRACT
Objective In this paper,the harmful effects and mechanisms induced by traditional Chinese medicine were expounded by combining the mechanism of programmed cell death and inflammatory reaction.It is expected to provide data support and theoretical reference for the rational use of traditional Chinese medicine and toxicology research.Methods By systematically analyzing the correlation between cell death and inflammatory response,the molecular mechanisms of pyroptosis,programmed cell necrosis and ferroptosis at home and abroad were summarized,and the harmful outcomes induced by traditional Chinese medicine were further discussed.Results Different toxic traditional Chinese medicines and their active ingredients have different tolerances to biological organisms.Programmed cell death is an important molecular mechanism for the toxicity of traditional Chinese medicines.Its signaling pathways are complex and diverse and are often accompanied by inflammatory reactions.Both of them have a certain effect on the toxic effects of traditional Chinese medicine.Conclusion Traditional Chinese medicine can provide inflammatory mediators for inflammatory response pathways through cell death or change the physiological balance of cells,thereby inducing inflammatory cascade reactions and promoting harmful outcomes in various systems of the body under the dual effects of cell death and inflammatory response.
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
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
Improper control of depth of anesthesia is not only detrimental to the rapid and stable recovery of anesthesia, but also affects the postoperative outcome of patients. Therefore, accurate control of anesthesia depth is an urgent clinical and scientific problem in the field of anesthesiology. At present, different algorithm models derived from electroencephalogram (EEG) signals are used to monitor the depth of anesthesia, but they cannot meet the requirements of anesthesiologists to accurately evaluate the depth of anesthesia. In recent years, the research on the mechanism and modulation of anesthesia-related neural network suggests that it has potential value as a method to monitor depth of anesthesia. Anesthesia-related neural networks mainly include sleep-wake circuit, thalamic-cortical circuit and corticocortical network. A thorough understanding of the neural network involved in the loss of consciousness caused by anesthesia will guide the depth of anesthesia monitoring more accurately and provide possibility for improving the quality of clinical anesthesia resuscitation.
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.

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.
