Objective To explore the effects of acupoint application of midnight-noon ebb-flow with hour-prescription of points on dysfunction for sufferers with senile osteoporosis(SOP).Methods In this study,76 patients with SOP in clinic in this hospital were recruited and randomly divided into the experimental group(n=38) and the control group(n=38) in accordance with random number table.Both were on the basic treatment of Caltrate D.The experimental group performed acupoint application of midnight-noon ebb flow with hour-prescription of points,while the control one performed common acupoint application.Oswestry Disability Index(ODI) was used to evaluate the dysfunction before,after 4 weeks and 8 weeks of intervention.SF-36 was adopted to evaluate the patients' quality of life before and after 8 week's intervention.Results The ODI scores of the experimental group after 4 weeks and 8 weeks were lower than those of the control group(P＜0.01).Repeated ANOVA indicated that the scores of ODI in group effect,time effect and interaction effect were of statistical significance(P＜0.01).Further comparison showed that the scores of ODI in three different time sections suggested that the latter time point were lower than those of the former time point(P＜0.01).The scores of eight dimensions of SF-36 after the intervention of the experimental group were higher than those of the control group(P＜0.05).Conclusion The acupoint application of midnight noon ebb flow-with hour-prescription of points can effectively improve the dysfunction whose curative effect enhanced with time increasing and improve the quality of life.

Objective:To compare the effects of different doses of ticagrelor on microcirculation, inflammatory factors and cardiac function in older adult patients with coronary heart disease after percutaneous coronary intervention (PCI).Methods:A total of 250 older adult patients with coronary heart disease who received PCI in The First People's Hospital of Wenling, China between March 2019 and March 2020 were included in this study. They were randomly assigned into group A and group B, with 125 patients per group. The group A was subjected to staged exercise and oral ticagrelor (45 mg once, twice a day). The group B was given staged exercise and oral ticagrelor (90 mg once, twice a day). Platelet function (maximum platelet aggregation rate, P2Y12 reaction unit), microcirculation (the index of microcirculatory resistance, circulatory flow reserve), inflammatory factor levels (high-sensitivity C-reactive protein, tumor necrosis factor alpha, interleukin-6), cardiac function recovery (left ventricular ejection fraction, 6-minute walk test, maximal oxygen consumption), cardiovascular adverse events, and bleeding events were compared between the two groups.Results:After treatment, maximum platelet aggregation rate and P2Y12 reaction unit in group B were (28.79 ± 3.52)% and (132.36 ± 12.16) U, respectively, which were significantly lower than those in group A [(33.45 ± 4.60)%, (146.79 ± 13.52) U, t = 8.99, 8.87, both P < 0.001]. After treatment, the index of microcirculatory resistance in group B was significantly lower than that in group A [(26.43 ± 4.51) vs. (29.68 ± 5.14), t = 5.31, P < 0.001]. Circulatory flow reserve in group B was significantly higher than that in group A [(2.16 ± 0.62) vs. (1.61 ± 0.50), t = 7.72, P < 0.001]. After treatment, tumor necrosis factor alpha, interleukin-6 and high-sensitivity C-reactive protein in group B were (39.54 ± 6.74) ng/L, (19.68 ± 4.06) ng/L, (5.98 ± 1.35) mg/L, respectively, which were significantly higher than those in group A [(28.26 ± 6.15) ng/L, (15.33 ± 3.87) ng/L, (4.83 ± 1.28) mg/L, t = 13.82, 8.67, 6.91, all P < 0.001]. After treatment, left ventricular ejection fraction, 6-minute walk test, maximal oxygen consumption in group B were (37.39 ± 5.10)%, (443.28 ± 29.64) m, (19.69 ± 3.57) L/min, respectively, which were significantly higher than those in group A [(34.64 ± 4.86)%, (410.45 ± 25.76) m, (17.33 ± 3.27) L/min, t = 4.36, 9.34, 5.45, all P < 0.001]. There was no significant difference in total incidence of cardiovascular events between the two groups (χ 2 = 0.05, P > 0.05). The incidence of bleeding events in group A was significantly lower than that in group B (4.80% vs. 13.60%, χ 2 = 5.79, P < 0.05). Conclusion:Compared with ticagrelor 90 mg/d, ticagrelor 180 mg/d can more greatly improve platelet function and microcirculation, reduce inflammatory reaction, promote the recovery of cardiac function, and reduce bleeding events in older adult patients with coronary heart disease after percutaneous coronary intervention.

Objective To observe the clinical features and evaluate the risk factors affecting prognosis in patients with secondary sepsis of gastrointestinal perforation (GIP). Methods A retrospective cohort study was conducted, and the patients with GIP admitted to the Department of General Surgery of Affiliated Shuyang People's Hospital of Xuzhou Medical University from January 1, 2014 to April 30, 2017 were enrolled, according to the presence or absence of sepsis occurrence, they were divided into GIP with and GIP without sepsis groups. The difference of gender, age, the time between the onset of GIP and the occurrence of sepsis, infection situation, body temperature, heart rate, respiratory frequency, white blood cell count (WBC), systemic inflammatory response syndrome (SIRS) in accord with standard, C-reactive protein (CRP), blood sugar, mean arterial pressure (MAP), lactic acid, number of cases having undergone laparoscopic surgery, sequential organ failure score (SOFA) and quick sequential organ failure score (qSOFA), Glasgow coma score(GCS), length of stay in intensive care unit (ICU), the total length of stay in hospital were compared;the status of survival and prognosis was assessed on day 30 by the Glasgow Outcome Scale (GOS). The indicators with statistical significance in the two groups were brought into the Cox regression model to analyze the independent risk factors affecting the prognosis of the patients. Results Fifty-eight patients with GIP were enrolled in this study. Among them, 22 cases developed secondary sepsis (GIP with sepsis group, there were 50.0% cases with single organ failure and 50.0% cases with multiple-organ failure, cases only in accord with 0-1 SIRS criteria accounting for 81.8%, and the mortality of secondary sepsis being 31.8%). No sepsis occurred in 36 patients (GIP without sepsis group). In GIP with sepsis group, the age, blood glucose, lactic acid, SOFA score, qSOFA, and the length of stay in ICU were significantly higher than those of GIP without sepsis group [age (years): 68.7±15.9 vs. 56.1±17.2, blood glucose (mmol/L): 6.9±2.3 vs. 5.9±1.2, lactic acid (mmol/L): 2.9±1.3 vs. 1.2±0.7, SOFA score: 5.6±3.2 vs. 0.5±0.4, qSOFA score: 1.0±0.9 vs. 0.3±0.1, the length of stay in ICU (days): 1.0 (0-4.0) vs. 0.1 (0-2.0), all P < 0.05], while MAP, GCS, and GOS scores in GIP with sepsis group were significantly lower than those in GIP without sepsis group [MAP (mmHg, 1 mmHg =0.133 kPa): 83.6±18.7 vs. 100.0±14.3, GCS score: 12.8±3.5 vs. 14.5±0.5, GOS score: 3.5±1.9 vs. 4.9±0.2, all P < 0.01]. Cox multivariable regression analysis showed: only low MAP and low GCS score were the independent risk predictors of death outcome for GIP with sepsis, the relative risk (RR) was 0.896 [95% confidence interval (CI) = 0.815-0.984, P = 0.022] and 0.585 (95%CI = 0.395-0.866, P = 0.007) respectively. Conclusion Patients with secondary sepsis following GIP have relatively high morbidity and much more risk factors, but only low MAP and low GCS score are closely associated with its high risk of death.

This study reported two women with extreme obesity who underwent metabolic surgery due to their mutations in leptin receptor (LEPR).Genomic DNA was extracted from the anticoagulant blood samples of the two patients and their parents.A panel of genes related to metabolic diseases or whole exon sequencing was screened and the results were confirmed by Sanger sequencing.This is the first time that these three mutations in LEPR were reported.Two patients complained insatiety and early-onset obesity since childhood at clinics.Patient 1 was a 39-year-old woman with height 150 cm,weight 130 kg,and BMI 57.8 kg/m2.Serum leptin level was 156.4 μg/L.A homozygous mutation of c.2317G＞T was found in exon 15 of LEPR gene in patient 1,which was descended from her father and mother respectively.Patient 2 was a 37-year-old woman with height 158 cm,weight 167 kg,and BMI 67 kg/m2.Serum leptin level was 193.4 μg/L.Genetic analysis showed compound heterozygous mutations of c.1482delT and c.1892C ＞ A.Her father showed heterozygous c.1482delT mutation,and her mother carried heterozygous c.1892C ＞ A mutation.Two patients all underwent metabolic surgery with body weight reduction of about 22 kg and 40 kg respectively after first six months.However,the follow-up studies showed that the body weight of patient 1 rebounded to pre-surgery level in two years and patient 2 did not further lose weight in the following six months.

Objective: To evaluate the therapeutic efficacy and safety of immunosuppressive therapy (IST) combined with recombinant human thrombopoietin (rhTPO) for severe aplastic anemia (SAA) in pediatric patients. Method: A retrospective case-control study was conducted and the clinical data of 45 pediatric patients with de novo SAA admitted to the Anemia Diagnosis and Treatment Center of Chinese Academy of Medical Sciences & Blood Disease Hospital during the period from December 2009 to December 2014 were analyzed. Among them, 15 patients were treated with the regimen of IST together with rhTPO and 30 patients were given IST treatment only. The variation characteristics of the peripheral blood routine as well as the transfusion of blood products was dynamically observed, and the therapeutic efficacy was assessed respectively after 3, 6 and 12 months after the treatment. In the meantime, adverse effects related to rhTPO application were recorded. Thereafter, the statistics of the two groups were compared by non-parametric rank sum test. Result: Among 45 pediatric patients, there were 26 male and 19 female, and the median age was 11 years (6-14). The number of patients received good hematological response(complete remission (CR) plus good partial response (GPR)) in the combinatory group versus vs. the IST group was 6 vs. 3 patients (χ²=3.906, P=0.048) at the 3rd month, 7 vs. 7 patients (χ²=1.568, P=0.210) at the 6th month, and 13 vs. 14 patients (χ²=6.667, P=0.01) at the 12th month respectively. For those achieved good hematological response at the 3rd month, the amount of platelets transfusion and red blood cells transfusion of the combined group were both less than that of the IST group during the period from the 10th to the 12th weeks (platelets transfusion: 1.4 U vs. 2.9 U, t=-3.523, P=0.002; red blood cells transfusion: 0.8 U vs. 2.6 U, t=-2.392, P=0.026). No serious adverse effect related to rhTPO application was observed in the IST combined with rhTPO group. Conclusion Application of rhTPO can improve the short-term therapeutic efficacy of IST for pediatric SAA, alleviate transfusion dependence, and has a good safety profile.

OBJECTIVETo compare the clinical efficacy differences between acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method and traditional acupoint plaster therapy for senile osteoporosis (SOP).

METHODSWith randomized controlled blind design, 76 SOP patients with deficiency of liver and kidney syndrome were randomly divided into an observation group and a control group, 38 cases in each one. Based on oral administration of caltrate D, the patients in the observation group were treated with acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method at Yingu (KI 10), Taixi (KI 3), Dazhong (KI 4), Fuliu (KI 7) and Zhiyin (BL 67), while the patients in the control group were treated with traditional acupoint plaster therapy. Each plaster therapy lasted for 6 h, once a day; there was an interval of 2 d after consecutive 5-day treatment; 4 weeks were taken as one course, and totally 2 courses were given. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the pain and dysfunction before intervention, after 4 weeks and 8 weeks intervention. Osteoporosis symptom rating sale and quality of life questionnaire of the European foundation for Osteoporosis (QUALEFFO-41) were adopted to evaluate the TCM syndrome and quality of life before and after 8-week intervention.

RESULTSAll the outcomes were significantly improved after treatment in the two groups (<0.01,<0.05); after 4 weeks and 8 weeks of treatment, the VAS and ODI in the observation group were lower than those in the control group (all<0.05). Repeated ANOVA indicated the VAS and ODI were significant in group effect, time effect and interaction effect (all<0.01). Further comparison showed that VAS and ODI at later time points were lower than those in the early time points (all<0.01). After the treatment, the scores of TCM syndrome and QUALEFFO-41 in the observation group were lower than those in the control group (all<0.05). The effective rate was 85.7% (30/35) in the observation group, which was superior to the effective rate in the control group[74.3%(26/35),<0.05].

CONCLUSIONSThe acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method is superior to traditional acupoint plaster therapy in improving pain, dysfunction, TCM syndrome and quality of life in SOP patients; in addition, its clinical efficacy is significant.

Finite element method (FEM) was used to investigate the biomechanical properties of three types of surgical fixations of U-shaped sacral fractures. Based on a previously established and validated complete lumbar-pelvic model, three models of surgical fixations of U-shaped sacral fractures were established: ① S1S2 passed through screw (S1S2), ② L4-L5 pedicle screw + screw for wing of ilium (L4L5 + IS), and ③ L4-L5 pedicle screw + S1 passed through screw + screw for wing of ilium (L4L5 + S1 + IS). A 400 N force acting vertically downward, along with torque of 7.5 N·m in different directions (anterior flexion, posterior extension, axial rotation, and axial lateral bending), was exerted on the upper surface of L4. Comparisons were made on differences in separation of the fracture gap and maximum stress in sitting and standing positions among three fixation methods. This study showed that: for values of separation of the fracture gap produced by different operation groups in different positions, L4L5 + S1 + IS was far less than L4L5 + IS and S1S2. For internal fixators, the maximum stress value produced was: L4L5 + IS > L4L5 + S1 + IS > S1S2. For the intervertebral disc, the maximum stress value produced by S1S2 is much larger than that of L4L5 + S1 + IS and L4L5 + IS. In a comprehensive consideration, L4L5 + S1 + IS could be prioritized for fixation of U-shaped sacral fractures. The objective of this research is to compare the biomechanical differences of three different internal fixation methods for U-shaped sacral fractures, for the reference of clinical operation.

Hypoxia is a common feature of solid tumors. As transcription factors, hypoxia-inducible factors (HIFs) are the master regulators of the hypoxic microenvironment; their target genes function in tumorigenesis and tumor development. Intriguingly, both yes-associated protein (YAP) and its paralog transcriptional coactivator with a PDZ-binding motif (TAZ) play fundamental roles in the malignant progression of hypoxic tumors. As downstream effectors of the mammalian Hippo pathway, YAP and/or TAZ (YAP/TAZ) are phosphorylated and sequestered in the cytoplasm by the large tumor suppressor kinase 1/2 (LATS1/2)-MOB kinase activator 1 (MOB1) complex, which restricts the transcriptional activity of YAP/TAZ. However, dephosphorylated YAP/TAZ have the ability to translocate to the nucleus where they induce transcription of target genes, most of which are closely related to cancer. Herein we review the tumor-related signaling crosstalk between YAP/TAZ and hypoxia, describe current agents and therapeutic strategies targeting the hypoxia-YAP/TAZ axis, and highlight questions that might have a potential impact in the future.

Objective To investigate the relationship between exposure to famine in early life stage and hypertension phenotype and grade in middle and old age. Methods People born between 1951 and 1965 in the 2015 China Health and Elderly Care Follow-up Survey were included in the study, and were divided into unexposed group, fetal exposed group, childhood exposed group and adolescent exposed group according to the time of famine occurrence and birth year of the participants. Logistic regression model was used to explore the effects of different famine exposure periods in early life stage on hypertension classification （including normal high value, grade I, grade II and grade III） and phenotype （including isolated systolic hypertension[ISH], isolated diastolic hypertension [IDH] and combined systolic and diastolic hypertension [SDH]）. Results Compared with unexposed group, fetal famine exposure （OR=1.59, 95% CI :1.10-2.30）, childhood famine exposure （OR=1.67, 95% CI :1.04-2.70） and adolescent famine exposure （OR=3.42, 95% CI : 2.51-4.66） were the risk factors for ISH. Only famine exposure during adolescence （OR=1.54, 95% CI: 1.07-2.21） was a risk factor for SDH. In addition, fetal famine exposure （OR=1.41, 95% CI: 1.05-1.89） and adolescent famine exposure （OR=2.22 , 95% CI: 1.71-2.88） were risk factors for developing grade I hypertension. Famine exposure in childhood （OR=2.45, 95% CI: 1.21-4.94） and famine exposure in adolescence （OR=2.45, 95% CI: 1.44-4.19） were risk factors for grade 2 hypertension. Conclusion Famine exposure in early life stage was associated with the phenotype and grade of hypertension. Therefore, balanced nutrition in early life is important to prevent hypertension in adulthood.
