Objective:To evaluate the implementation effects of critical illness insurance of New Cooperative Medical System(NCMS) on the occurrence rate and economic burden of major disease expenditure.Methods:Based on the peasant household data of China Family Panel Studies(CFPS) in 2014.the two-part model was applied to analyze the changes in major disease occurrence and burden after the implement of insurance.Results:NCMS critical illness insurance did not reduce the occurrence of critical disease expenditure,but signally cut down the economic burden of serious illness peasants in central and eastern China.Conclusion:The implementation effect of NCMS critical illness insurance was well in central and eastern China,but was poor in western China;the prevention and health care system of NCMS should be built,while the implementation plans and compensation level of critical illness insurance should be improved in western region.

OBJECTIVE:To establish a method for the simultaneous content determination of berberine hydrochloride,phello-dendrine hydrochloride and magnoflorine in Phellodendron amurense decoction piece,and to campare the contents of the 3 ingredi-ents in different grades of P. amurense decoction piece. METHODS:HPLC was performed on the column of Phenomenex Luna C18 with mobile phase of acetonitrile-0.05 mol/L KH2PO4 (gradient elution) at a flow rate of 1 ml/min,the detection wavelength was 280 nm,the column temperature was 30 ℃,and injection volume was 5 μl. RESULTS:The linear ranges were 0.387 0-7.740 μg for berberine hydrochloride(r=0.999 9),0.044 4-0.888 0 μg for phellodendrine hydrochloride(r=0.999 8)and 0.048 0-0.960 0 μg for magnoflorine(r=0.999 9);RSDs of precision, stability and reproducibility tests were lower than 3%, recoveries were 95.61%-103.22%(RSD=2.80%,n=6),96.18%-102.80%(RSD=1.84%,n=6) and 97.93%-102.78%(RSD=1.84%,n=6). CONCLUSIONS:The method is simple and accurate,and can be used for the contents determination of berberine hydrochloride, phellodendrine hydrochloride and magnoflonine in P. amurense. The contents of berbenine hydrochloride and phellodendrine hydro-chloride in the first-grade decation piece are higher than those in the second-grade decoction piece,and the content of magnoflorine in both decoction pieces shows no discernible differences.

Objective To investigate the correlation between BMI and insulin dose in diabetic patients after short-term continuous subcutaneous insulin infusion (CSII). Methods Three hundred patients with type 2 diabetes mellitus (T2DM) were enrolled and randomized into the normal weight (BMI < 23 kg/m2) group, overweight (BMI 23 ~ 25 kg/m2) group and obesity (BMI≥25 kg/m2) group. The metabolic and anthropometric parameters of each group were compared and the related factors which may influence insulin dose were analyzed. Results The insulin dose per weight in the overweight group or in the obesity groups was significantly lower than that in the normal weight group. Weight and BMI were negatively correlated with the insulin dose per weigh. Conclusions Differences of glycemia level , β-cell function and insulin resistance exist in Chinese type 2 diabetes patients with different BMI. The stratification of BMI should be considered before estimating the insulin dose by body weight in CSII therapy.

OBJECTIVETo investigate the presence of cancer stem cells (CSCs) exist in non-small cell lung cancer (NSCLC) and explore the relationship among the expressions of CD133, Notch1, and vascular endothelial growth factor (VEGF) and their relations with the clinicopathological parameters of the patients.

METHODSA total of 305 specimens of NSCLC and 80 normal lung tissue specimens were analyzed for CD133, Notch1, and VEGF protein expressions by immunohistochemical staining.

RESULTSIn NSCLC specimens, the positivity rates of CD133, Notch1, and VEGF were 48.9%, 43.9%, and 45.6%, respectively, significantly higher than those in normal lung tissues (10.0%, 15.0%, and 0%, respectively, P<0.01). The expression levels of CD133, Notch1, and VEGF proteins were significantly correlated with the tumor grades, lymph node metastasis, TNM stages, and postoperative survival time of the patients (P<0.01). A positive correlation was found among the expression levels of CD133, Notch1, and VEGF proteins. Kaplan-Meier survival analysis showed a significantly lower overall mean survival time of the patients positive for CD133, Notch1, and VEGF than that of the negative patients (P<0.001). Cox regression analysis suggested that positive expressions of CD133 and Notch1 were independent prognostic factors of NSCLC (P<0.05).

CONCLUSIONSCD133, Notch1, and VEGF may play important roles in the occurrence, progression, invasion, and metastasis of NSCLC. CD133 and Notch1 have important values for predicting the prognosis and evaluating disease progression of the patients.

Lysine specific demethylase1 (LSD1) is a flavin adenine dinucleotide (FAD)-dependent monoamine oxidase. Studies have confirmed that aberrant expression of LSD1 is closely related to tumor metastasis and proliferation, and is currently one of the important targets for tumor-targeted therapy. In addition, LSD1 is involved in the development of various conditions such as neurodegenerative diseases, cardiovascular diseases, and inflammatory responses. Currently, several inhibitors have been developed for the clinical research stage. In this paper, the structure and mechanism of action of LSD1 and the research progress of LSD1 inhibitors are briefly introduced to provide some reference for the design and development of novel LSD1 inhibitors.

OBJECTIVETo explore the expression of Snail and Slug in primary cervical squamous cell carcinoma (CSCC) and their relationship with KAI1 expression.

METHODSThe expressions of Snail, Slug, and KAI1 proteins were examined by immunohistochemistry in 154 specimens of CSCC tissues, 50 specimens of cervical intraepithelial neoplasm (CIN), and 40 specimens of normal cervical tissues.

RESULTSThe positivity rates of Snail, Slug, and KAI1 expression were 0%, 2.5%, and 95.0% in normal cervical tissues, 32.0%, 34.0% and 64.0% in CIN tissues, and 66.2%, 66.9%, and 43.5% in CSCC tissues, respectively, showing significant differences in the rates among the 3 groups (P<0.05). The expressions of Snail, Slug, and KAI1 were significantly correlated with the histological grades of the tumor, depth of invasion, lymph node metastasis, International Federation of Gynecology and Obstetrics (FIGO) stages, and postoperative survival time (P<0.05). The expressions of Snail and Slug were positively correlated (r=0.752, P<0.001), and both of them were negatively correlated with the expression of KAI1 (P<0.001). Kaplan-Meier analysis showed that patients positive for Snail and Slug had significantly lower survival rates than the negative patients (P<0.001), while a positive expression of KAI1 was associated with a higher survival rate of the patients. Cox regression analysis identified Snail, KAI1, and FIGO stage as independent factors that affected the outcomes of CSCC (P<0.05).

CONCLUSIONThe expressions of Snail, Slug, and KAI1 are related to the tumor grade, FIGO stage, invasive depth, lymph node metastasis, and prognosis of CSCC, and their combined detection can help estimate the outcomes of the patients.

Objective To quantify any therapeutic effect of cyclic movement training combined with functional electrical stimulation for improving lower limb motor function and ability in the activities of daily life after stroke.Methods Seventy stroke survivors were randomly divided into a control group and an experimental group,each of 35.Both groups were given conventional rehabilitation,including cyclic training,but the experimental group was additionally provided with functional electrical stimulation of the quadriceps,hamstrings,anterior tibialis and gastrocnemius at the affected side.Before and after four weeks of treatment the Fugl-Meyer lower limb (FMA-L) and balance (FMA-B) assessments were performed and a modified Barthel index (MBI) was assigned to each subject to quantify functioning.Results Before the treatment,no significant differences were observed between the two groups in any of the measurements.But after four weeks of treatment the average FMA-L,FMA-B and MBI scores of the experimental group were all significantly better than before the treatment and significantly better than the control group's averages.Conclusion Cyclic movement training combined with functional electrical stimulation can improve the lower limb motor function of stroke survivors and their ability in the activities of daily life.

OBJECTIVE: To explore the genetic basis for 7 families with gonadal mosaicism for Duchenne muscular dystrophy (DMD). METHODS: For the 7 families presented at the CITIC Xiangya Reproductive and Genetic Hospital from September 2014 to March 2022, clinical data were collected. Preimplantation genetic testing for monogenic disorders (PGT-M) was carried out for the mother of the proband from family 6. Peripheral venous blood samples of the probands, their mothers and other patients from the families, amniotic fluid samples from families 1 ~ 4 and biopsied cells of embryos cultured in vitro from family 6 were collected for the extraction of genomic DNA. Multiplex ligation-dependent probe amplification (MLPA) was carried out for the DMD gene, and short tandem repeat (STR)/single nucleotide polymorphism (SNP)-based haplotypes were constructed for the probands, other patients, fetuses and embryos. RESULTS: The results of MLPA showed that the probands and the fetuses/probands' brothers in families 1 ~ 4, 5, 7 had carried the same DMD gene variants, whilst the probands' mothers were all normal. The proband in family 6 carried the same DMD gene variant with only 1 embryo (9 in total) cultured in vitro, and the DMD gene of the proband's mother and the fetus obtained through the PGT-M were normal. STR-based haplotype analysis showed that the probands and the fetuses/probands' brothers in families 1 ~ 3 and 5 have inherited the same maternal X chromosome. SNP-based haplotype analysis showed that the proband from family 6 has inherited the same maternal X chromosome with only 1 embryo (9 in total) cultured in vitro. The fetuses in families 1 and 6 (via PGT-M) were both confirmed to be healthy by follow up, whilst the mothers from families 2 and 3 had chosen induced labor. CONCLUSION Haplotype analysis based on STR/SNP is an effective method for judging gonad mosaicism. Gonad mosaicisms should be suspected for women who have given births to children with DMD gene variants but with a normal peripheral blood genotype. Prenatal diagnosis and reproductive intervention may be adapted to reduce the births of further affected children in such families.
