ABSTRACT

With the development of social economy and improvement of people's health condition, life expectancy continues to extend and people are more concerned about the quality of life. Nowadays people's attention has shifted from living longer lives to living healthier lives. Life expectancy can only reflect the length of life, but not the health condition and quality of life. Meanwhile, healthy life expectancy contains death and disability information, which comprehensively reflects the length and quality of life and evaluates the health status of the population comprehensively. Through literature search and review, the article summarized the research on healthy life expectancy in recent years, including the concept proposal, index development, calculation, and application progress of health life expectancy. The research methods of healthy life expectancy are summarized in order to provide academic reference for further research.

ABSTRACT

To investigate the effects of miR-31 on TLR4/NF-κB signaling pathway and apoptosis-related proteins in dextran sulfate sodium (DSS) induced mouse colon colitis. Methods: ① Mouse model of colon colitis: 1% DSS was used to induce mouse ulcerative colitis (UC). Fourteen FVB non-transgenic mice were randomly divided into control group (n= 6), DSS group (n= 8), and 16 FVB miR-31 transgenic mice were randomly divided into miR-31 overexpression group (n= 8), miR-31 overexpression +DSS group (n= 8). DSS was dissolved in water and administered to mice by drinking water. The DSS group and miR-31+DSS group drank 1% DSS water in the first week, normal sterilized water in the second week, and 1% DSS water in the third week, after 5 weeks, the modeling was completed, then the colon tissues of the mice were collected. Western blot and IHC were used to detect the expressions of NF-κB p65, TLR4, Bax and Bcl-2 proteins in mouse colon tissue, TUNEL was used to detect apoptosis of mouse colon tissues. ② Cell culture experiments: Transfection of miR-31mimic and inhibitor by lipofectamine resulted in overexpression or knockdown of miR-31 in human colon epithelial cell line HCT 116 cells, each group was repeated three times and cells were collected 48 h later, Western blot was used to detect the expressions of NF-κB p65 and TLR4 protein. ① In animal experiments, compared with the control group, the expression levels of NF-κB p65, TLR4 protein and apoptotic cell index in the DSS group and miR-31 overexpression group in mouse colon tissue were significantly increased (P<0.05 or P<0.01), and the Bcl-2 / Bax ratio was significantly reduced (P<0.05 or P<0.01); and compared with the DSS group, the expression levels of NF-κB p65, TLR4 protein and apoptotic cell index in the miR-31+DSS group were significantly increased (P<0.01), while the Bcl-2/Bax ratio was significantly decreased (P<0.01). ② In cell experiments, compared with the control group, the expression levels of NF-κB p65 and TLR4 protein in the over-expressed miR-31 group of HCT 116 cells were significantly increased (P<0.05 or P<0.01), the expressions of NF-κB p65 and TLR4 protein in miR-31 knockdown group were decreased (P<0.05). miR-31 promotes the development of colitis by promoting TLR4/NF-κB signaling pathway and mediating apoptosis of intestinal epithelial cells.

ABSTRACT

ObjectiveThe genotypes and drug-resistance mutation of hepatitis B virus (HBV) are closely related to the progression of chronic hepatitis B (CHB) and effects of medication. This study was to identify the genotypes and drug-resistance mutation genes of HBV in West Guangxi and provide some laboratory evidence for anti-HBV treatment.MethodsWe collected serum samples from 869 CHB patients with HBV DNA >1.0×103 IU/mL, all from West Guangxi, between January 2016 and March 2018. We detected the genotypes and drug-resistance mutation genes in the patients by PCR and reverse dot blot (PCR-RDB).ResultsA total of 7 genotypes were identified in the patients, including genotypes B in 304 cases (34.98%), C in 268 (30.84%), D in 147 (16.92%), B+C in 28 (3.22%), B+D in 22 (2.53%), C+D in 1 (0.12%) and B+C+D in 1 (0.12%). Drug-resistance mutation was observed in 63 cases (7.25%), including 31 cases with genotype C (49.21%) and 19 with genotype B (30.16%). Fourteen gene mutation patterns were found in all, including rt204I, rt181V, rt236T, rt180M+rt204V, and rt180M+rt204V+rt204I, among which, rt180M+rt204V exhibited the highest mutation frequency (17.46%). There was a statistically significant difference between the mutation rates of genotypes B and C (19% vs 31%, P < 0.05).ConclusionCHB patients in West Guangxi have a wide variety of genotypes of HBV, mainly including genotypes B and C, with a high rate and complicated patterns of drug-resistance mutation, which has provided some reference for anti-HBV treatment in West Guangxi.

ABSTRACT

<p><b>OBJECTIVE</b>To study the associations of pedestrian injuries with age, income and educational level in Shanghai and to analyze the relative disease burden.</p><p><b>METHODS</b>Information on pedestrian-related cases and deaths were collected from 494 hospitals and mortality registry systems from 1992 to 2010, and a multistage cluster sampling survey conducted in 2006. Logistic regression model was used in the analyses.</p><p><b>RESULTS</b>The age group of 5-9 had the highest mortality and morbidity among children. Mortality increased obviously among those aged 60 or above. Individuals with an educational level under the primary school and with the lower family average income were more likely to suffer pedestrian-related injuries. Multivariate Logistic analysis demonstrated that lower income and lower educational level increased the risk of pedestrian injuries with the odds ratio of 1.40 (95% CI: 1.15-1.71) and 1.70 (95% CI: 1.20-2-40), respectively. About 13.54% of the share of GDP for the healthcare, social security and welfare industries in Shanghai was occupied by the burden of pedestrian-related injuries in 2006.</p><p><b>CONCLUSION</b>Pedestrian-related injury has inverse association with victims' income and educational level. Children of 5-9 years old and adults over 60 with lower educational level and lower monthly income are the target persons to be intervened.</p>

ABSTRACT

PURPOSE: Although the polymorphisms of erythrocyte complement receptor type 1 (CR1) in patients with malaria have been extensively studied, a question of whether the polymorphisms of CR1 are associated with severe malaria remains controversial. Furthermore, no study has examined the association of CR1 polymorphisms with malaria in Chinese population. Therefore, we investigated the relationship of CR1 gene polymorphism and malaria in Chinese population. MATERIALS AND METHODS: We analyzed polymorphisms of CR1 gene rs2274567 G/A, rs4844600 G/A, and rs2296160 C/T in 509 patients with malaria and 503 controls, using the Taqman genotyping assay and PCR-direct sequencing. RESULTS: There were no significant differences in the genotype, allele and haplotype frequencies of CR1 gene rs2274567 G/A, rs4844600 G/A, and rs2296160 C/T polymorphisms between patients with malaria and controls. Furthermore, there was no association of polymorphisms in the CR1 gene with the severity of malaria in Chinese population. CONCLUSION: These findings suggest that CR1 gene rs2274567 G/A, rs4844600 G/A, and rs2296160 C/T polymorphisms may not be involved in susceptibility to malaria in Chinese population.

ABSTRACT

[ Objective] To discuss the characteristics of death among elderly people aged 60 years and above in Shanghai, who were classified into different age groups, and to provide a basis for making public health policy. [ Methods] On the basis of the data covering whole population death registry system in Shanghai, data on the elders aged 60-plus was collected and classified into 3 age groups according to WHO standards for descriptive analysis. [ Results] The crude death rate among the elders aged 60-plus in shanghai in 2014 was 3 001.76/105 ,accounting for 88.37%of the total mortality.The crude death rate of male was higher than that of female in each age group.The main causes of death in 60-74 age-group were cancer and coronary heart disease ( CHD) which had shorter course of disease with worse prognosis. The main causes of death in 75-89 age-group were cardiovascular and cerebrovascular diseases and chronic obstructive pulmonary disease ( COPD) which had longer course.The main causes of death in 90-pluse group included functional degradation and accidental fall, apart from cardiovascular and cerebrovascular diseases and COPD.And 54.35%of the elders aged 60-plus died in hospital, while 34.12%at home,and 6.63%at nursing home.The proportion of death at home was higher in non-central urban area than in central urban area.And the proportion of death in hospital decreased with increasing age. [ Conclusion] The proportion of the elderly death was large in total mortality.As the characteristics of death varied in different age groups, government should adopt different prevention and control measures.Rational allocation of medical and rehabilitation resources, as well as terminal care, need more attention and exploration by all institutions concerned.

ABSTRACT

<p><b>BACKGROUND</b>Hyperinsulinemia, insulin-like growth factor (IGF)-I and -II (IGF-II) are associated with increased risk of endometrial carcinoma. Insulin receptor isoform A (IR-A) is more frequently expressed in endometrial carcinoma than in normal endometrial tissues. To better understand their roles in endometrial carcinoma, we investigated the effects of insulin, IGF-I, and IGF-II in endometrial carcinomas cells with different IR-A expression levels.</p><p><b>METHODS</b>To explore the role of IR-A in mediating the activity of IGF-I, IGF-II, and insulin, we investigate the cellular proliferation of endometrial carcinoma cell lines RL95-2 and RL95-2-IR-A by MTS assays. Then we examined the protein kinase Akt phosphorylation and extracellular signal-regulated kinase (ERK) 1/2 phosphorylation in both cell lines by Western blotting. The effect of IGF-II and AG1024 on cell cycle progression and apoptosis was assessed by flowcytometry. To examine whether the effects of IGFs were mediated by IR-A, we blocked IGF-I receptor (IGF-IR) in both cell lines using AG1024, an IGF-IR-specific inhibitor.</p><p><b>RESULTS</b>IGF-I and IGF-II significantly enhanced proliferation of both cell lines (P < 0.05). By contrast, insulin significantly increased proliferation of RL95-2-IR-A cells only (P < 0.05). IGF-I and IGF-II significantly increased pAkt levels in RL95-2 cells and pERK1/2 levels in RL95-2-IR-A cells (all, P < 0.05). Insulin increased pERK1/2 levels in RL95-2-IR-A cells only (P < 0.05). LY294002 and PD98059 inhibited the specific signaling activities and cellular proliferation. After AG1024 pretreatment, neither IGF-I nor IGF-II affected pAkt levels in RL95-2 cells. IGF-II, but not IGF-I, increased pERK1/2 levels in RL95-2-IR-A cells. After AG1024 pretreatment, the proliferation rate and DNA content corresponding to the S phase increased and apoptosis decreased significantly in IGF-II-treated RL95-2-IR-A cells only (P < 0.05).</p><p><b>CONCLUSIONS</b>The proliferation effect of insulin is mediated by IR-A. When IR-A dominates in a cell line, IGF-II activated cell proliferation mainly through the ERK1/2 pathway. On the other hand, IGF-II activated cell proliferation mainly through the Akt pathway. IR-A can at least partly mediate the proliferative and anti-apoptotic effects of IGF-II through the ERK1/2 pathway.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To report two de novo acute myeloid leukemia (AML) patients with t(11;22)(q23;q11.2) and summarize the clinical and biological characteristics.</p><p><b>METHODS</b>Bone marrow cells morphology, immunophenotype, chromosome karyotype, fluorescence in situ hybridization (FISH), PCR and gene sequencing were performed. Clinical manifestation and routine laboratory tests were analyzed.</p><p><b>RESULTS</b>The patients were diagnosed as AML-M₂ and AML-M₅ by morphology and immunophenotype results. Both patients carried t(11;22)(q23; q11.2) and one of them carried an additional chromosome abnormality. MLL-SEPTIN5 fusion transcript was identified in two patients by RT-PCR and sequencing. The two patients got hematologic complete remission after induction chemotherapy with daunorubicin, homoharringtonine, and cytarabine (DHA) or daunorubicin and cytarabine (DA). One of them relapsed and died during consolidation therapy with intermediate-dose cytarabine.</p><p><b>CONCLUSION</b>Leukemia with t(11;22)(q23;q11.2) chromosome translocation met the clinical and laboratory manifestations of AML. The MLL-SEPTIN5 fusion transcript was the distinctively biological etiology. Patients with t(11;22)(q23;q11.2) were vulnerable to relapse after conventional chemotherapy and had poor prognosis. Allogeneic hematopoietic stem cell transplantation should be recommended as early as possible.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To examine the recent incidences and trends of childhood malignant solid tumors in Shanghai.</p><p><b>METHOD</b>Data from the population-based Shanghai Cancer Registry and related retrospective survey were used to analyze the patterns of incidence and trends of malignant solid tumors diagnosed between 2002 and 2010 in children aged 0-14 years. The distributions of incidences were described according to gender, age and cancer types which were classified according to International Classification of Childhood Cancer (ICCC). Annual age-standardized rates (ASRs) were adjusted by the world standard population. Approximate confidence intervals for standardized rate ratios (SRR) based Poisson distribution test-based methods were used to assess changes in incidence over the period 2002 - 2006 and 2007 - 2010.</p><p><b>RESULT</b>(1)A total of 868 cases of childhood malignant solid tumors were diagnosed in Shanghai during 2002 - 2010, accounting for 65.8% of all childhood cancers. The ASR of 2002 - 2010 was 80.2 per million for all solid tumors. (2) The ASR was higher in boys (86.3 per million) than in girls (73.8 per million) with SRR 1.2 (95%CI 1.0 - 1.3). Incidence rate was the highest in the first five years of life with 93.4 per million. The age-specific incidence rates in 5 - 9 and 10 - 14 age groups were 65.2 and 79.3 per million, respectively. (3) CNS tumors, lymphomas, germ cell tumors, neuroblastoma, and soft tissue sarcomas were the top 5 most common solid tumors in children, with the incidence rate of 23.8, 11.0, 7.8, 7.7 and 6.8 per million, respectively. The patterns of subgroups varied in different age groups. Blastomas, such as neuroblastoma, retinoblastoma, were more common in the children aged 0 - 4 years, whereas epithelial carcinomas and bone tumors developed more frequently in elder children aged 10 - 14 years. (4) Compared with the ASR in 2002 - 2006, the ASR for both genders in 2007 - 2010 had no substantial changes (78.7 per million in 2002 - 2006 and 82.9 per million in 2007 - 2010). However, among boys, the incidence rate in 2007 - 2010 was significantly higher than that in 2002 - 2006 with SRR 1.2 (95%CI: 1.0 - 1.4). For specific subgroups of cancer, there were no substantial changes. Some cautions should be taken when interpreting results involving a small number of cases per year and those with wide 95% confidence intervals.</p><p><b>CONCLUSION</b>The incidence rate of pediatric malignant solid tumors among males was higher than females during 2002 - 2010, and it differed among different age groups with the highest in the first five years of life. CNS tumor was the most common type of solid tumors in children. This was a unique characteristics comparing with adult reflected in disease spectrum and age of onset. The patterns of incidence and its trends for childhood malignant solid tumors in Shanghai could provide a basis for etiologic research and preventive interventions. The findings also suggest an urgent need for longer population-based surveillance to verify the pattern and changing trends.</p>

ABSTRACT

Objective To investigate the relationship between myocardial ischemia and slow coronary flow phenomenon with 99Tcm-methoxyisobutylisonitrile (MIBI) adenosine myocardial perfusion SPECT imaging. Methods Forty-four patients were divided to three groups according to the result of coronary angiography(CAG). There were GAG-positive(P-GAG) (n=12),slow coronary flow (CSF) (n =22),and normal coronary flow (NCF) (n = 10). Results of adenosine myocardial perfusion imaging were compared among these three groups. Semi-quantitative visual scoring method was used to evaluate the myocardial perfusion:0 = normal,1 = mild decrease,2 = moderate decrease,3 = severe decrease,4 = defect. Statistical analysis was performed using variance analysis,t-test and x2-test. Results No significance was observed at age ( t =0.27,0. 54 and 0. 59),sex (x2 = 0. 92),hypertension,hyperlipemia and diabetes (x2 = 1.23,all P > 0.05 ) among the three groups. A significantly higher frames of the coronary thrombolysis in myocardial infarction (TIMI) flow was noted in CSF than in NCF groups (33.7 ±5.5 vs 17.6 ±3.9,t = 9. 58,P <0. 001 ). The positive adenosine myocardial perfusion imaging rate were significant among these three groups with 100% (12/12) in P-CAG group,77.3% (17/22) in CSF group,and 20% (2/10) in NCF group. When using semi-quantitative visual scoring method,significantly higher average ischemia segments were noted in CSF group than in NCF group ( 1.06 ± 0.77 and 0. 91 ± 0.80,t = - 2. 02,P < 0. 05 ),but was less than that in P-CAG group (2.41 ±0.79,t =4. 54,P <0.001 ). The degree of ischemia of CSF group was higher than that in NCF group ( 8.01 ± 6.06,and 2.73 ± 2.60,t = - 2.07,P < 0.05 ) and was less than that in P-CAG group (14. 07 ±12. 77 ,t=1.44,P>0. 05). Conclusion Slow coronary flow phenomenon can be detected by adenosine myocardial perfusion image to offer the evidence of diagnosis and treatment for the chest pain patients with negative coronary angiography results.

<p><b>OBJECTIVE</b>To investigate the auditory function and the role of NKCC1 and alpha2 Na, K-ATPase in the potassium recycling of cochlea.</p><p><b>METHODS</b>NKCC1(+/-) / alpha2 Na, K-ATPase(+/-) mice model was established from NKCC1(+/-) and alpha2 Na, K-ATPase(+/-) mice. The auditory function of all strain mice were detected by auditory brainstem response (ABR) and endocochlear potential (EP) to investigate the role of NKCC1 and alpha2 Na, K-ATPase in the potassium recycling of cochlea. Furosemide and ouabain were applied to block the two channels in Castel mice line which can long-time maintain normal auditory function and then their auditory function was detected by ABR to authenticate the mode of potassium recycling in vivo and the relationship between cochlear potassium recycling and NKCC1(+/-) and alpha2 Na, K-ATPase.</p><p><b>RESULTS</b>The mean value for ABR thresholds in response to stimulus was elevated in NKCC1(+/-) and alpha2 Na, K-ATPase (+/-) mice [(38.49 +/- 12.29) dB and (53.32 +/- 7.62) dB) ] respectively, which was significantly increased compared with that observed in wild type mice [(23.13 +/- 3.78) dB, P < 0.05) ]; The EP value of NKCC1(+/-) [(78 +/- 7) mV] and alpha2 Na, K-ATPase(+/-) mice [(71 +/- 14) mV] was decreased compared with that of NKCC1(+/-) / alpha2 Na, K-ATPase(+/-) mice [( 86 +/- 11) mV]. The auditory function of NKCC1(+/-) / alpha2 Na, K-ATPase(+/-) mice could simulate the model of cochlear potassium recycling well. NKCC1 and Na, K-ATPase were great of importance in the potassium recycling, while the two ion channels were in restrict dynamic equilibrium. Castel mice line after administration with furosemide developed significant ABR threshold shifts (P < 0.05) compared with control group. Castel mice line after administration with ouabain also developed greatly significant ABR threshold shifts (P < 0.05) compared with control group. ABR threshold shifts in mice after administration both furosemide and ouabain was attenuated compared with only administration with furosemide (P < 0.01).</p><p><b>CONCLUSIONS</b>Ion channel NKCC1 and alpha2 Na, K-ATPase played important roles in the inner ear potassium recycling. Dysfunction of either of them could influence potassium concentration in the endolymph and lead to hearing loss subsequently. The role of NKCC1 and alpha2 Na, K-ATPase in cochlear potassium recycling was authenticated in vivo. The two ion channels contribute the key role for dynamic equilibrium in cochlear potassium recycling and are of great importance for the metabolism of potassium in the inner ear to maintain the normal auditory function.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To establish a mice model of aminoglycoside antibiotics (AmAn) induced ototoxicity. Then to investigate the sensitivity of AmAn induced ototoxicity in three mouse strains and effect of kanamycin on the expression of Na-K-2Cl co-transporter-1 (NKCC1) in stria vascularis.</p><p><b>METHODS</b>C57BL/ 6J, CBA/CaJ, NKCC1 +/- mice (each of twenty-four) were randomly divided into four experimental groups A, B, C and D (A kanamycin alone, B kanamycin plus 2, 3-dihydroxybenzoate, C 2, 3-dihydroxybenzoate alone, D control group). Mice were injected with kanamycin or/and 2, 3-dihydroxybenzoate for 14 days. Auditory function was measured by auditory brainstem response (ABR) and morphology of cochlea was observed by succinate dehydrogenase staining. Expression of NKCC1 was detected by immunohistochemistry.</p><p><b>RESULTS</b>Mice in group A developed significant ABR threshold shifts (P < 0.01), which were accompanied by out hair cells loss. Mice in group B significantly attenuated ABR threshold shifts with out hair cells loss (P <0.01). The immunostaining of NKCC1 in stria vascularis was attenuated significantly in group A compared with group D (P < 0.01) while the immunostaining in group B was enhanced than which in group A (P < 0.01). CBA/CaJ mice has the highest sensitivity to AmAn in three mouse strains.</p><p><b>CONCLUSIONS</b>An mouse model of AmAn induced ototoxicity could be established by administration of kanamycin. Kanamycin could inhibit the expression of NKCC1 in stria vascularis. 2, 3-dihydroxybenzoate could attenuate AmAn induced ototoxicity maybe by enhancing the expression of NKCC1. Mice that had the characteristic of presbycusis didn't show additional sensitivity of AmAn induced ototoxicity.</p>
