OBJECTIVE: Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA. METHODS: This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance. RESULTS: The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m²) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m²). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA. CONCLUSION Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.

Objective: To evaluate the relationship between the brain glucose metabolism and left ventricular function parameters, and to explore the cerebral glucose metabolism reduction regions in patients with ischemic heart disease (IHD). Methods: A total of 110 consecutive IHD patients who underwent gated (99)Tc(m)-sestamibi (MIBI) SPECT/CT myocardial perfusion imaging, gated (18)F-fluorodeoxyglucose (FDG) PET/CT myocardial and brain glucose metabolic imaging within three days in Beijing Anzhen Hospital from April 2016 to October 2017, were enrolled in this study. Left ventricular functional parameters of SPECT/CT and PET/CT including end-diastolic volume (EDV), end-systolic volume (ESV) and left ventricular ejection fraction (LVEF) were analyzed by QGS software. Viable myocardium and myocardial infarction region were determined by 17-segment and 5 score system, and the ratio of viable myocardium and scar myocardium was calculated. According to the range of viable myocardium, the patients were divided into viable myocardium<10% group (n=44), viable myocardium 10%-<20% group (n=36) and viable myocardium≥20% group (n=30). Pearson correlation analysis was used to analyze the correlation between the range of viable myocardium and scar myocardium and the level of cerebral glucose metabolism. Brain glucose metabolism determined by the mean of standardized uptake value (SUV(mean)) was analyzed by SPM. The ratio of SUV(mean) in whole brain and SUV(mean) in cerebellum were calculated, namely taget/background ratio (TBR). Differences in cerebral glucose metabolism among various groups were analyzed by SPM. Results: There were 101 males, and age was (57±10) years in this cohort. The extent of viable myocardium and the extent of scar, LVEF evaluated by SPECT/CT and PET/CT were significantly correlated with TBR (r=0.280, r=-0.329, r=0.188, r=0.215 respectively,all P<0.05). TBR value was significantly lower in viable myocardium<10% group, compared with viable myocardium 10%-<20% group (1.25±0.97 vs. 1.32±0.17, P<0.05) and viable myocardium≥20% group (1.25±0.97 vs. 1.34±0.16, P<0.05). Furthermore, in comparison with viable myocardium≥20% group, the hypo-metabolic regions of viable myocardium<10% group were located in the precuneus, frontal lobe, postcentral gyrus, parietal lobe, temporal lobe, and so on. Conclusions: There is a correlation between impaired left ventricular function and brain glucose metabolism in IHD patients. In IHD patients with low myocardial viability, the level of glucose metabolism in the whole brain is decreased, especially in the brain functional areas related to cognitive function.

On the base of the idea of traditional Chinese medicine as "disease prevention", the mode and the protocol of the moxibustion intervention for the group under quarantine after close contact with coronavirus disease 2019 (COVID-19) were explored. The group under quarantine after close contact with COVID-19 was taken as the subjects. By the non-contact physician-patient communication network platform co-developed by China Association of Acupuncture-Moxibustion, Hunan Provincial Association of Acupuncture-Moxibustion, Data Center of China Academy of Chinese Medical Sciences and Yuge Medicine Company, an exploratory randomized controlled trial was designed. A total of 100 cases were included and randomized into a moxibustion group and a conventional intervention group, 50 cases in each one. In the moxibustion group, moxibustion intervention was used. In the conventional intervention group, the conventional observation was adopted without moxibusiton intervention applied. The outcomes included the symptoms changes, e.g. anxiety, emotional disturbance, fatigue, headache and diarrhea, as well as whether quarantine release and the case confirmed or not, etc. The results were evaluated before intervention, in 14 days of intervention and 2 weeks after intervention separately. In this research, on the base of internet plus technology and with the internet communication platform adopted, through mobile phone WeChat App, it was to implement the subject screen, the random allocation and the instruction of moxibustion intervention as well as the quality control of patient's diary and data collection. It is anticipated that the significance and the implementation mode of moxibustion intervention can be assessed preliminarily for the group under quarantine after close contact with COVID-19.

Objective: To investigate the current practice of extracorporeal cardiopulmonary resuscitation (ECPR) for Chinese cardiac arrest patients after the publication of 2015 American Heart Association guidelines for cardiopulmonary resuscitation. Methods: A questionnaire was distributed to healthcare providers of emergency departments (EDs) and/or Intensive Care Units (ICUs) across 52 hospitals in China from August to November 2016. Data collection ended in February 2017. The questionnaire included three parts: (1) characteristics of the departments and the respondents; (2) knowledge about ECPR; (3) practice of ECPR in cardiac arrest patients (case volume, inclusion/exclusion criteria, ECPR procedure). The characteristics of the departments/hospitals were only answered by the head of the department. Results: A total of 1 952 (86.8%) respondents fulfilled the survey. Only 2.5% of the respondents from 3 of 52 hospitals performed ECPR. Among the three hospitals, the case number of ECPR were ≤5 per year and none of them had written ECPR procedures. Only one hospital had formal inclusion/exclusion criteria. The inclusion criteria included age between 18 to 60 years, suspected cardiogenic cardiac arrest, beginning of cardiopulmonary resuscitation <5 min after cardiac arrest and duration of cardiopulmonary resuscitation >10 min. The top three reasons for the nonuse of ECPR were unknown fields (31.2%), potential ECMO-related side effects (26.9%) and cost (18.7%). Conclusions: ECPR for cardiac arrest patients are not well understood by healthcare providers in the emergency department or ICUs and its application is still in the early stage in China. Educational training and other interventions are needed to promote the clinical practice.

Objective To understand the prevalence of Toxoplasma gondii infection among special populations in Nanjing City, so as to provide the reference for formulating the interventions for the prevention and control of T. gondii infections in this population. Methods The HIV/AIDS patients, tumor patients, pregnant women, and people with livestock and poultry breeding or processing works were selected as the study subjects from September to November 2015. The venous blood samples were collected from each participant for detecting IgG and IgM antibodies against T. gondii by ELISA. Results The overall prevalence of T. gondii infection was 10.2% in the study subjects in Nanjing City. The T. gondii infection rates were 12.2%, 11.3%, 4.0%, and 13.0% among the HIV/AIDS patients, tumor patients, pregnant women, and people with livestock and poultry breeding or processing works, respectively, and there was no statistically significant difference among the four groups (χ² = 5.668, P = 0.130). The prevalence of T. gondii infection was higher in men than in women (15.3% vs. 5.8%; χ² = 10.213, P = 0.001), and there were significant differences in the prevalence of T. gondii infection in terms of gender (χ² = 9.501, P = 0.023), education levels (χ² = 9.850, P = 0.043) or occupations (χ² = 8.983, P = 0.062). Conclusions The infection rate of T. gondii among the special population in Nanjing City is high. Therefore, the health education intervention should be strengthened in the follow-up work for the special population.

Arisaema heterophyllum Blume is one of the three medicinal plants known as traditional Chinese medicine Rhizoma Arisaematis (RA). RA has been popularly used to treat patients with convulsions, inflammation, and cancer for a long time. However, the underlying mechanisms for RA effects are still unclear. The present study was designed to determine the cytotoxicity of agglutinin isolated from Arisema heterophyllum Blume (AHA) and explore the possible mechanisms in human non-small-cell lung cancer A549 cells. AHA with purity up to 95% was isolated and purified from Arisaema heterophyllum Blume using hydrophobic interaction chromatography. AHA dose-dependently inhibited the proliferation of A549 cells and induced G phase cell cycle arrest. AHA induced apoptosis by up-regulating pro-apoptotic Bax, decreasing anti-apoptotic Bcl-2, and activating caspase-9 and caspase-3. In A549 cells treated with AHA, the PI3K/Akt pathway was inhibited. Furthermore, AHA induced increase in the levels of ER stress markers such as phosphorylated eukaryotic initiation factor 2α (p-eIF2α), C/EBP-homologous protein (CHOP), inositol-requiring enzyme 1α (IRE1α), and phosphorylated c-Jun NH-terminal kinase (p-JNK). AHA also induced autophagy in A549 cells. Staining of acidic vesicular organelles (AVOs) and increase in the levels of LC3II and ATG7 were observed in AHA-treated cells. These findings suggested that AHA might be one of the active components with anti-cancer effects in Arisaema heterophyllum Blume. In conclusion, cytotoxicity of AHA on cancer cells might be related to its effects on apoptosis and autophagy through inhibition of PI3K/Akt pathway and induction of ER stress.

OBJECTIVETo investigate the influence of CD117 expression on response of multiple myeloma patients to chemo-therapy.

METHODSA total of 65 cases of newly diagnosed multiple myeloma in our hospital from 2011 to 2013 were enrolled in this study. Cytogenetic abnormalities and immunophenotype were detected by using fluorescence in situ hybridization and flow cytometry before chemotherapy. The therapeutic efficacy of patients was evaluated after 4 cycles of PAD or TAD regimen.

RESULTSThe positive rates of 1q21 amplification, RB1: 13q14 deletion, D13S319: 13q14.3 deletion, IgH: 14q32 rearrangement and p53: 17p13 deletion were 32.2%, 40%, 40%, 20% and 3.1% respectively; the positive rates of CD38, CD138, CD56, CD117, CD20 were respectively 100%, 100%, 60%, 20%, 10.8%; the positive rates of CD19 and CD10 were 4.6% and 4.6% respectively; the positive CD22, CD7, CD5, CD103 did not found in any patients. The therapeutic efficacy of CD117⁻ patients was better than that of CD117⁺ patients (P < 0.05), there was no correlation of the remaining indicators with efficacy; the proportion of CD117⁺ patients with β2-microglobulin ≥ 5.5 mg/L was significantly higher than that of CD117⁻ patients (P < 0.05); the rest of baseline data had no significant difference (P > 0.05).

CONCLUSIONCD117 can be used as an indicator for evaluating efficacy of patients with newly diagnosed multiple myeloma.

OBJECTIVETo explore the effect of valproic acid(VPA) on anti-myeloma activity of Doxorubicin(DOX) or Melphalan(MEL) and its related mechanism.

METHODSHuman multiple myeloma(MM) cells were treated with VPA of non-toxic dose in absence and presence of DOX or MEL at different concentrations (ie. IC10, IC20, IC40). The cell proliferation was detected by MTT method. Western blot was used to detect the expression levels of autophagy-related proteins (LC3, ATG5, ATG7) and acetylated histone H4K16ac.

RESULTSCell proliferation inhibition markedly increased in VPA plus DOX or MEL as compared with DOX or MEL alone (P<0.05). Both LC3 and H4K16ac expression levels in co-treatment were between VPA and DOX or MEL treated alone. Importantly, VPA of non-toxic dose not only augmented the anti-myeloma activity of DOX or MEL, but also down-regulated the autophagy-related protein expression and increases H4K16ac protein levels.

CONCLUSIONH4K16ac can inhibit the transcription of autophagy-related genes, The VPA enhance the anti-myeloma activity of DNA-damaging drugs, at least in part, via H4K16ac-mediated suppression of cytoprotective autophagy.
