Objective:To investigate the impact of social determinants of health on the inequality of child health and health care utilization.Methods:Information of 1 118 children aged 0 to 16 is extracted from the Chinese Family Panel Studies(CFPS)year 2008 cross sectional survey data for the analysis.Age standardized concentration curves and concentration indices are employed to assess the inequalities for incidence of low birth weight,self reported good health,adequate timing of breast feeding,health insurance coverage and incidence of catastrophic health expenditures for these children.Concentration indices are decomposed to four levels of social determinants of health(community,family,mother and individual level)to understand their contributions to health inequality respectively.Results:There are health inequalities existing in the investigated children,among which social factors at mother and family level have the largest contribution.Conclusion:To respond to the call by the WHO to achieve health equity through action on the social determinants of health in a generation,the inequalities of health and health care utilization amongst Chinese children should be put on the policy agenda,and social policies should intervene from multiple social dimensions,especially from family and mother levels.

This paper presents successful surgical treatment of a-trial fibrillation by a simplified maze procedure (SMP) in 3 patients. All of them suffered from rheumatic heart valvular diseases complicated with atrial fibrillation (AF) for 3 to 10 years. Their heart function were in class III-IV(NYHA). The diameter of the left atrium varied from 52-58 mm and the cardiothoracic ratio 0. 64-0.70. The open heart operation was performed under conventional cardiopulmonary bypass combined with systemic hypothermia and using cardio-plegia for myocardial protection. After finishing the modified maze operation,mitral valve replacement was performed in 2 cases and mitral and aortic valve replacement together with tricuspid annuloplasty in one. Sinus rhythm recovered after cardiac ressuscitation and was maintained in the early postoperative period in all 3 cases. However, with in 3 months after the operation, one patient died of cerebrovascular accident, probably a complication of anticoagulant therapy. The other 2 patients remained well with normal sinus rhythm and their heart function was in class I 3 years after the operation. The clinical results indicate that mitral valve or mitral and aortic valve replacements plus simplified maze procedure to abolish atrial fibrillation may improve the postoperative hemodynamics by recovery of the sinus rhythm.

Objective To report the use of self expanding metallic stents in treatment of benign tracheobronchial stenosis. Methods Nineteen patients with benign tracheobronchial stenosis were treated with implantation of self expanding stents (Ultraflex, Microvasive). Results Stents produced immediate improvement in clinical pulmonary sign and symptoms. Pulmonary function tests in 10 patients demonstrated a mean improvement in FEV1of 45%, FVC of 38%. Following up duration ranged from 10-18 months. Complications included recurrent pneumonia in 3 patients, airway obstruction due to granuloma formation in 2 patients, and stent migration in 1 patient. They were treated successfully with antibiotic therapy, laser therapy, and stent reimplantation, respectively. Conclusion Self expanding metallic stent implantation is a feasible and effective method of treating benign tracheobronchial stenosis.

Objective To observe the long-term result of brachial plexus injury.Methods41 cases of brachial plexus injury were divided into the non-operation group (n=11), neurolysis group (n=17), never repair group (n=13). Retrospective analysis of the charts and follow-up survey of the functional recovery of shoulder joint and elbow joint were carried out. Gilbert score and Mallett score were adopted at the follow-up.ResultsIn the non-operation group, 9 cases were graded as excellent, 1 case as good, 1 case as bad. In the neurolysis group, 2 cases were graded as excellent and good. In the never repair group, 2 cases of shoulder joint obtained excellent, 4 cases of elbow joint were grade as good.ConclusionThe simple surgical result of brachial plexus injury is not satisfactory, it should be combined with postoperative rehabilitation.

Objective:China was categorized as one of the 68 countdown countries to achieve the United Nations Millennium Development Goals (MDG) 5. This paper aimed to analyze the situation of maternal survival, and coverage of proven cost effective interventions in China, where specific attention was paid to disparities. Methods: National maternal and child mortality surveillance data were used to estimate maternal mortality ratio (MMR). Coverage for proven interventions was analyzed based on National Health Services Survey, where experts' consultations were made for complementation. Results: There had been a significant reduction of MMR in China, however great disparities existed, with rural Ⅱ to Ⅳ areas experiencing 2 to 5 times higher maternal mortality risks than urban areas and accounting for over 70% maternal mortality burdens. Postpartum hemorrhage, pregnancy associated hypertension, embolism and sepsis were the leading causes, and over 75% of the maternal mortality was caused by preventable or curable causes. Maternal health services utilization decreased in accordance with region' s development level. Socioeconomic factors like financial difficulties were the main obstacles hindering access of care.Even those who made deliveries in hospitals faced different probabilities in receiving qualified care according to their socioeconomic standings. Conclusion: China is on track to achieve MDG 5, however great disparities exist. It is necessary to specifically target rural types Ⅱ to Ⅳ areas. Major causes of maternal mortality which can be prevented or averted through the provision of essential obstetrical care. Yet as compared with maternity health needs, insufficient coverage of maternal and child health (MCH) care services and poor service quality are the leading predisposing factors contributing to maternal mortality in China.

Objective To investigate the influence o f ultraviolet C (UVC) irradiation of different doses on expression of basic fibrob last growth factor (bFGF) in granulation tissues of wound in rats. MethodsThirty Wistar rats were recruited and three wounds wer e made in each rat. The UVC irradiation of different doses (60mJ/cm2 and 15mJ/ cm2) were performed daily in two of the three wounds in each rat, respectively , and the UVC irradiation lasted for three days. The expression of bFGF both at the mRNA level and the protein level were observed by the methods of in situ hyb ridization and immunohistochemistry at 7 days, 14 days, 21 days after wound was made, respectively. ResultsAt the 7 days after woun d was made, the expression of bFGF in irradiation groups were higher than that i n the control group ( P

Objective To investigate the effect of passive exercise on neural functional recovery after peripheral nerve crushed injury.MethodsThe effect of passive exercise on early peripheral nerve regeneration and recovery of motor function were observed with electrophysiological and histological indexes compared with that of the splinting group.ResultsThe nerve conduction of training group was faster than that in the splinting group,and the latency of compound muscle action potentials(CMAP)was shorter(P<0.05).The thickness of myelin sheath,average numbers of myelinated nerve fibera per area and diameter of regenerating axon in training group were larger than those in the splinting group(P<0.05).The wet weight of sural triceps of training group were bigger than that of the splinting group(P<0.01).ConclusionThe passive exercise can improve the early recovery of motor function and neural regeneration after peripheral nerve crushed injury.

AIM:To investigate the effect of gastrodin(GAS)on microglia-mediated inflammatory response after hypoxic-ischemic brain damage(HIBD)neonatal mice by regulating the expression of JAK1/STAT1 pathway through C-C chemokine recepeor 5(CCR5).METHODS:Forty-eight C57BL/6J mice at about 10 days after birth were randomly divided into sham group,HIBD model group and HIBD+GAS group.BV-2 microglia were divided into control(Con)group,oxygen glucose deprivation(OGD)group,oxygen glucose deprivation with gastrodin intervention(OGD+GAS)group,GAS group,Maraviroc(MVC)group,OGD+MVC group,and OGD+MVC+GAS group.The mRNA expression of CCL4 and CCR5 were detected by RT-qPCR.The protein expression of CCR5,p-JAK1,p-STAT1,tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)were detected by Western blot.The expression of CCR5,p-JAK1 and p-STAT1 in cells were observed by immunofluorescence staining.RESULTS:(1)Compared with sham group,the expression levels of CCL4 and CCR5 mRNA,and CCR5,p-JAK1 and p-STAT1 proteins were significantly higher in the ischemic side of the corpus callosum in HIBD group(P＜0.05).(2)Compared with Con group,the protein levels of CCR5,p-JAK1 and p-STAT1 significantly increased in BV-2 cells of OGD group(P＜0.05).The protein levels of CCR5,p-JAK1 and p-STAT1 in BV-2 cells of OGD+GAS group were significantly lower than those of OGD group(P＜0.05).(3)Maraviroc did not cause significant BV-2 cell death in the 0～80 μmol/L range.The p-JAK1 and p-STAT1 protein levels in MVC+OGD group were significantly lowered compared with OGD group(P＜0.05),but no significant difference was found between MVC+ OGD and OGD+MVC+GAS groups.CONCLUSION:Gastrodin can exert neuroprotective effects via CCR5/JAK1/STAT1 signaling pathway.

This paper reported a case of severe COVID-19 in the recovery stage with acute lymphoblastic leukemia treated by integrated traditional Chinese and western medicine， with the intention of shedding light on the clinical diagnosis and treatment of similar conditions. The patient， who had acute lymphoblastic leukemia， developed COVID-19 infection during the bone marrow suppression period after chemotherapy. Treatment with western medicine was mainly anti-infection， symptomatic management， and supportive care. During the recovery stage， considering the patient's chemotherapy history and disease progression， the overall syndrome was identified as deficiency of both qi and yin and binding of phlegm and blood. Based on the “state-target” combined treatment strategy， herbal prescriptions were selected and modified to address the “deficiency state”， “disease target”， and “symptom target”. In addition to western medicine， the patient was administered with Shengmai Powder （生脉散） and Compound Zhebei Granules （复方浙贝颗粒） in its modifications to boost qi， nourish yin， and reinforce healthy qi， nourish and cool the blood， ultimately achieving satisfactory therapeutic effects.
