Journal of Zhejiang Chinese Medical University 2017;41(4):298-300
[Objective]The paper was designed to introduce the Professor YE Jin's personal clinical experience which can provide an effective means for other pediatrician.[Method]By introducing the Professor YE Jin's personal clinical experience,we summarize the effective therapies about the infantile recurrent abdominal pain(RAP). [Result]According to the Professor YE Jin, the pathomechanism of RAP includes mainly cold stagnation, the indigestion, parasite and Qi stagnancy. RAP caused bycoldcan be treated from warming the middle-energizer and fending off the cold,RAP resulting from retention of food can be cured by removing the retention and invigorating the stomach, RAP incurred by ascaris can be cured by relieving ascariasis,expelling parasite and purgation simultaneously,and RAP resulting from Qi stagnation can be cured by soothing liver, regulating qi activity, rather than relieving pain merely. Based on the above-mentioned theory,she tends to use Liquorice and prefers Paeonia a lot in curing the disease, that is always effective in clinic as a result.The recurrence rate is also lower.One case was provided for verification.[Conclusion]Professor YE Jin thinks that warming the middle-energizer and fending off the cold, removing the retention and invigorating the stomach, the RAP can be improved the curative effect,and that can provide another idea for other clinicians.

Objective To investigate the present status of Chinese patent medicine with realgar (As2S2) and to research arsenic dissolution in different pH values. Methods Data on the amount of Chinese patent medicine with realgar, the content of realgar, the method of taking medicine and so on were collected from the Chinese traditional medicine protection and criterions issued by the Chinese Ministry of Health in 2005, and evaluated the using status of Chinese patent medicine with realgar. The realgar powder was dissolved in solutions at different pH values (1, 3, 5, 7, 9, 11) in 37℃ water for 4 h, respectively, then arsenic was determined with cold trap hydride generation atomic absorption spectrometry to calculate the amount of dissolved arsenic. Results One hundred and twenty-one (3.13%) realgar medicaments were recorded in a total of 3 860 various Chinese patent medicaments, including 74 medicaments with both realgar and cinnabar (HgS) . Of all medicaments with realgar, 97 medicaments (80.17%) were for oral application, 10 medicaments (8.26%) were for external application, and 14 medicaments (11.57%) were for both oral and external application. 45 medicaments with realgar (1.17%) could be used in children; 108 medicaments with realgar (89.26%) contained arsenic 15%; The relative amount of arsenic in medicaments with realgar was from 0.46% to 27.52%. Daily intake of arsenic was 500 mg for 11 medicaments (9.09%). Only inorganic arsenic (iAs) was detected when 1 mg realgar was dissolved in solution with pH values of 1, 3, 5, 7, 9, 11. The levels of dissolved iAs seemed increased with the pH values, which were 1.58 ?g, 1.24 ?g, 1.57 ?g, 1.62 ?g, 2.28 ?g and 4.76 ?g, respectively. Conclusion Considering the common use of realgar in Chinese patent medicine and the high level of arsenic in realgar, the potential danger can not be ignored. It is possible that arsenic in realgar may be much easier to be absorbed in intestine than in stomach.

Objective To establish the expression of membrane-bound HLA-G1-G4 isoforms in choriocarcinoma cell line JAR and to investigate its roles in NK cytotoxicity in vitro. Methods Stable expression of HLA-G1, -G2, -G3 and -G4 in JAR cells was established by gene cloning and transfection.HLA-Gtranscripts and protein expression in the transfected JAR cells was tested by RT-PCR, flow cytometry, Western blot and immunocytochemistry, respectively. High-affinity peptide KIPAQFYIL pulsing was performed to evaluate its effects on HLA-G expression. Effects of HLA-G1-G4 isoforms on NK cytotoxicity was performed with lactic dehydrogenase (LDH) releasing method. Results RT-PCR, Western blot and immunocytochemistry results showed that exogenous HLA-G1-G4 gene were successfully transfected and proteins were stably expressed in the HLA-G negative JAR cells; Flow cytometry data showed that only HLAG1, but not HLA-G2-G4 isoform was detectable in those transfected JAR cells and the peptide pulsing did not affect their expression status. However, all HLA-G1-G4 isoform expressed JAR cells could significantly decreased the NK cell cytotoxicity (P<0.05). Conclusion HLA-G1-G4 isoform expression could dramatically inhibit NK-92 cell lysis, indicating that membrane-bound HLA-G isoforms are importantly immunotolerant and may play immune regulation roles in various physio-pathological situations.

Human leukocyte antigen G ( HLA-G) is a member of the non-classical HLA classⅠb family. It is considered to play a crucial role in immune tolerance. A unique feature of HLA-G is the struc-tural diversity as surface expressed and as secreted molecules, which is mainly attributed to alternative spli-cing of the primary transcript. HLA-G can promote the invasion and metastasis of tumor cells through various ways. In addition, HLA-G has been described included in exosomes. Exosomes released by most cell types are nano-sized vesicular bodies that contain lipid bilayer and rich contents. As a new marker for diseases, exosomes are extensively involved in the occurrence and development of diseases. Recent studies have found that exosomes can express soluble HLA-G, which reveal a new way by which HLA-G regulates tumor micro-environment. In this review, we focus on the expression of HLA-G on exosomes to provide new thoughts for the early detection and treatment of tumors.

Objective To explore the predicting value of peripheral blood CD20+ CD24hi CD38hi regulatory B cells (Bregs) on the prognosis of elderly patients with sepsis.Methods A prospective study was conducted. Septic patients aged > 65 years old, compliance with diagnostic criteria for Sepsis-3, admitted to emergency and emergency intensive care unit (ICU) of Shanghai East Hospital of Tongji University from April 2016 to February 2017 were enrolled. Procalcitonin (PCT), C-reaction protein (CRP) and lactate (Lac) were routinely measured. According to the worst clinical index value within 24 hours, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and sequential organ failure assessment (SOFA) score were recorded. The concentrations of peripheral blood CD20+ CD24hi CD38hi Bregs were measured by flow cytometry at 1, 3 and 7 days after diagnosed in elderly patients. All patients with sepsis were followed up for 28 days and then divided into death group and survival group according to 28-day outcome. The difference of clinic data and Bregs were compared between the two groups. The significant different factors of elderly sepsis patients were analyzed by binary logistic regression analysis. The correlation between Bregs level and other indicators was analyzed by Spearman correlation. The receiver operating characteristic curve (ROC) was used to evaluate the prognosis value of Bregs in elderly patients with sepsis.Results Fifty-eight patients were enrolled in the study, with 38 male and 20 female; age of (79.91±7.97) years; 32 in sepsis group, 26 in septic shock group; 35 deaths, 28-day mortality rate was 60.3%. APACHE Ⅱ score and SOFA score in death group exhibited much higher than that in survival group (APACHE Ⅱ: 18.14±4.52 vs. 14.91±3.56, SOFA: 8.80±4.56 vs. 6.35±3.00, bothP < 0.05), the Bregs was significantly decreased at 1, 3 and 7 days in death group [cells/μL: 0.70 (0.20, 1.40) vs. 1.50 (0.70, 2.20), 0.54 (0.20, 1.00) vs. 1.42 (1.10, 2.12), 0.25 (0.10, 0.50) vs. 0.80 (0.50, 1.00), allP < 0.05]. Correlation analysis showed that the concentrations of peripheral blood Bregs at 1 day in elderly patients with sepsis was negatively correlated with APACHE Ⅱ score (r = -0.351,P = 0.007), and it was not correlated with PCT, CRP, Lac or SOFA score. It was shown by binary logistic regression that Bregs [odds ratio (OR) = 1.865,P = 0.028] and APACHE Ⅱ score (OR = 0.853,P = 0.026) were independent risk factors for elderly sepsis outcome. It was shown by ROC curve analysis that the prognostic value of the levels of Bregs at 1, 3, 7 days and APACHE Ⅱ score were higher in the elderly patients with sepsis, and the area under ROC curve (AUC) and 95% confidence interval (95%CI) were 0.842 (0.647-0.954), 0.770 (0.564-0.911), 0.888 (0.703-0.977), 0.855 (0.661-0.961), respectively, allP < 0.01. The 7-day Bregs was most powerful to predict outcome, when the cut-off value was 0.50 cells/μL, the sensitivity was 72.73% and specificity was 86.67%. Conclusions The level of peripheral blood CD20+ CD24hi CD38hi Bregs could predict the clinical outcome of elderly patients with sepsis.
