ObjectiveTo compare the therapeutic efficacy of acupuncture plus medication versus using Chinese medication or acupuncture alone in treating perimenopausal syndrome.MethodNinety patients with perimenopausal syndrome were randomized into 3 groups, 30 in each group, to respectively receive acupuncture plus Chinese medication, Chinese medication alone, and acupuncture alone, totally for 3 months. Modified Kupperman index was adopted to evaluate therapeutic efficacy.ResultAfter intervention, the Kupperman scores decreased significantly in all three groups (P<0.01). The Kupperman score of the acupuncture-medication group was markedly superior to that ofthe medication group and acupuncture group (P<0.05).Conclusion Combination of acupuncture and medication can significantly improve the symptoms of perimenopausal syndrome, and is valuablein clinic.

Objective:To investigate the sleep quality and relative factors of the people aged 18years or over in Tianjin Municipality.Methods:The participants came from the Tianjin Mental Health Survey conducted from Ju-ly to December in 2011.Total of 11618 residents aged 18 years or over were selected randomly among the general population and finished the Pittsburgh Sleep Quality Index (PSQI)for assessment of sleep quality and General Health Questionnaire (GHQ-12)for screening out the individual with possible mental disorders.The PSQI total score >7 was defined as poor sleep quality.Chi-square test and Wilcoxon rank sum test was used to conduct univa-riable analysis,and logistic regression was used to analyze the related factors to poorer sleep quality.Results:In this sample,980 people had poorer sleep quality,with the adjusted prevalence rate in Tianjin was 6.6%.Logistic regres-sion analysis showed risk factors to poorer sleep quality were female (OR =1.47,95%CI:1.19 -1.82),older age (30 -39 years old,40 -49 years old,50 -59 years old,60 -69 years old,70 years or older,OR =1.72(95%CI:1.10 -2.69),2.55(95%CI:1.66 -3.91),4.41 (95%CI:2.85 -6.83),5.34(95%CI:3.32 -8.59),5.40(95%CI:3.21 -9.08),at his/her own expense on medicare (OR =1.52,95%CI:1.15 -2.00),unemployment (OR =1.46,95%CI:1.05 -2.03)or retirement (OR =1.45,95%CI:1.02 -2.06),smoking (OR =1.49,95%CI:1.22-1.83),difficulty to engage in daily work or activities due to physical illness (OR =2.30,95%CI:1.85 -2.85), and GHQ -12 score ≥ 4 (OR =6.51,95%CI:5.46 -7.46).Conclusion:Although the prevalence rate of poorer sleep quality in the people aged 18 years or over in Tianjin is lower,the problem is common and should not to be ignored.

Objective: To observe the effect of a novel targeted agent enzastaurin alone or in combination with gefitinib on ge-fitinib-resistant human non-small cell lung cancer cells to explore the rational drug combination. Methods: CCK-8 assay was used to measure the cell proliferation. Combination index ( CI) was calculated by Chou-Talalay method to assess the efficacy of the combination therapy. The flow cytometry (FCM) was used to analyze the change in the cell cycle. Results:In 72h, the IC50 value of gefitinib and enzastaurin for the lung cancer NCI-H460 cells was 6. 99μmol·L-1 (95%CI:3. 55-13. 79μmol·L-1 ) and 7. 25μmol·L-1 (95%CI:4. 77-1. 02 μmol·L-1), respectively. The inhibition effect on the cell proliferation was stronger in the combination treatment than that in the monotherapy (P<0. 05), and the simultaneous treatment showed the most significant inhibition effect (P<0. 01). The IC50 value of gefitinib for H460 cells in the simultaneous administration group, the sequential administration group with gefitinib used first and the sequential administration group with enzastaurin used first was 0.006 μmol·L-1(95%CI:0.002-0.020μmol·L-1), 0.02μmol·L-1(95%CI:0.011-0.037 μmol·L-1) and 0.085 μmol·L-1(95% CI:0.042-0.170μmol·L-1, respectively. The CI of the simultaneous administration group was lower than one when the gefitinib concentration was above 0. 05μmol·L-1 . The cell cycle distribution result indicated that the simultaneous administration group had significantly increased G0/G1 proportion (P<0. 05) and induced cell cycle arrest at G1 phase. Conclusion:Protein kinase C inhibitor enzastaurin combined with EGFR inhibitor gefitinib shows a synergistic effect, suggesting that the combination treatment of the two drugs might be a new strategy for the follow-up therapy of gefitinib-resistant non-small cell lung cancer.

Objective:To investigate the clinicopathological features and prognosis of IgA nephropathy (IgAN) patients with gross hematuria.Methods:The clinical and pathological data of 490 primary IgAN patients admitted in the Affiliated Hospital of Qingdao University from January 2010 to June 2019 were analyzed. Patients were divided into gross hematuria group and non-gross hematuria group. The clinical and pathological features and prognosis were compared between the two groups. All patients were diagnosed by kidney biopsy, and followed up until June 30, 2020. Kaplan-Meier survival curve was used to examine the renal survival,and Cox regression model was used to analyze the risk factors affecting renal survival in two groups.Results:Among 490 patients there were 111 patients (22.7%) in the gross hematuria group and 379 patients (77.3%) in the non-gross hematuria group. Age, hypertension, 24-h urine protein, serum creatinine, blood uric acid, blood triglycerides, total blood cholesterol level, mesangial cell hyperplasia (M1), the proportion of renal tubular atrophy or renal interstitial fibrosis (T1/2) in gross hematuria group were lower than those in non-gross hematuria group ( P<0.05), while the estimated glomerular filtration rate (eGFR) in gross hematuria group was higher than those in non-gross hematuria group ( P<0.05). Four hundred and twenty six patients (86.9%) were followed up for at least 6 months, including 93 patients in gross hematuria group and 333 patients in non-gross hematuria group. There was no statistically significant difference in treatment method between the two groups ( P>0.05). The incidence of end-point events in non-gross hematuria group was higher than that in gross hematuria group [18.6%(62/333) vs. 6.5%(6/93), χ2=8.023, P<0.05]. Kaplan-Meier survival analysis showed that the cumulative renal survival rate of the gross hematuria group was higher than that of the non gross hematuria group (χ2=11.44, P<0.001). Multivariate Cox regression analysis showed that urine protein>1 g/24 h, eGFR<60 ml·min -1·(1.73 m 2) -1, hypertension, hyperuricemia and the elevated serum IgA/C3 were risk factors for renal survival [ HR(95% CI)=3.457(1.137-10.514),2.736(1.073-6.977),2.720(1.144-6.465),2.789(1.102-7.060),1.070(1.009-1.135), all P<0.05]. Conclusions:IgAN patients with gross hematuria has less severe kidney damage and higher cumulative renal survival rate than non-gross hematuria patients. Urinary protein>1.0 g/d, hypertension, hyperuricemia and the elevated serum IgA/C3 are risk factors for adverse end-point events, to which timely attention and corresponding treatment should be given.

OBJECTIVE: To study the function of Qiyeling Decoction in inducing apoptosis of transplanted human lung adenocarcinoma cells A549 in nude mice. METHODS: Nude mice with transplanted A549 tumor were randomly divided into the untreated control group (group A), chemotherapy treated group (group B), chemotherapy plus Qiyeling Decoction treated group (group C), Qiyeling Decoction treated group (group D) and managed correspondingly. The tumor volume was measured and calculated into tumor weight. The apoptosis of tumor cells were examined using in situ cell apoptosis detection kit. RESULTS: The tumor weight was lower obviously in groups B, C and D than that in group A (P<0.05). The apoptosis of tumor cells was lower obviously in groups B, and C than that in group D (P<0.05). Cells in group A appeared perfect differentiation during the early stage and apoptosis later. CONCLUSION: Qiyeling Decoction can induce A549 cell apoptosis in nude mice.

Objective To explore the effect of gestational hypertension on multiple organ system in neonates. Methods A total of 100 newborns whose mother had pregnancy complicating primary hypertension admitted to our hospital from December 2011 to December 2012 were selected and divided into preeclampsia group (n=53), gestational hypertension group (n=47) according to the blood pressure during pregnancy. Meanwhile, 100 newborns with healthy mother were selected as control group including 12 term infants and 88 premature infants. Data including birth weight, length and head circumference, Apgar score, the percentage of amniotic lfuid pollution, placental abruption and fetal distress, Neonatal Behavioral Neurological Assessment (NABA) score, serum level of creatine kinase, pulmonary arterial pressure, thyroid function, blood glucose, blood routine, cranial MRI parameters were collected and compared among three groups. Results In preeclampsia group, the gestational age, birth weight and head circumference, 1-min and 5-min Apgar scores were lowest while the ratio of low birth weight infants was highest among three groups, and the differences were signiifcant (P<0.05). In preeclampsia group, the rates of antenatal abnormalities (amniotic lfuid meconium III degree pollution, placental abruption and fetal distress) and complications (severe infection, myocardial damage, neonatal polycythemia, liver and kidney damage, hypoglycemia, hypothyroidism and respiratory failure) were highest among three groups, and the differences were signiifcant (P<0.01). In preeclampsia group, the red blood cell count, the levels of hemoglobin, hematocrit and thyroid stimulating hormone were signiifcantly higher than those in the other two groups ( P<0.05 ), and the white blood cell and platelet count was signiifcantly lower than that in the control group (P<0.05). The passive muscle tension scores in preeclampsia group were signiifcantly lower than those in the other two groups (P<0.05).The abnormity rate of cranial MRI in preeclampsia group was highest among three groups, and the difference was signiifcant (P<0.01). Conclusions Gestational hypertension may cause multisystem disorders in newborns, such as fetal intrauterine growth restriction, endocrine system disorders, heart dysfunction, increased blood viscosity, delayed neurodevelopment. The severity of gestational hypertension is associated with the adverse impact on the multiple systems in neonates.

Objective To analyze the clinical data and TUBB4A mutation of hypomyelination with atrophy of the basal ganglia and cerebellum (HABC)in a family,thus to provide accurate genetic counseling and prenatal diagno-sis for this family with HABC,and also to provide clinical experience for the diagnosis of HABC in China.Methods The clinical data of the proband and her family members were collected at the Department of Pediatrics,Peking Univer-sity First Hospital,December 201 4,including medical history,physical signs,and brain MRI,biochemical tests and metabolic disease screening.The associated gene of hereditary leukoencephalopathy was screened for the proband and her family members were screened by targeting -high -throughput sequencing technology,and then the genetic varia-tions were verified by Sanger sequencing.With those detection methods,the gene mutation was confirmed,and then ge-netic features were analyzed.Results Clinical features were as follows:nystagmus as the first symptom,and motor and mental retardation,dystonia and ataxia followed.Brain MRI indicated hypomyelination of white matter and atrophy of the basal ganglia and cerebellum.The clinical diagnosis of HABC was established based on the clinical features and brain MRI features above.Genetics features showed that one novel TUBB4A c.974G >T heterozygous missense muta-tion was found from the proband,which caused an amino acid change from the Trp into Leu (p.Trp325Leu).Both of her parents with normal phenotype were of wild -type in this site.Conclusions The proband from this family was diagnosed clinically based on her clinical data.One novel TUBB4Ac.974G > T (p.Trp325Leu)was founded in this study.Therefore,the spectrum of TUBB4A mutation will be expanded.In addition,this study elucidated clinical and genetic characteristics in this family with HABC,which may lay a solid foundation for the accurate genetic counseling and prenatal diagnosis.This study reported the first case of HABC caused by TUBB4A mutation in China.

Objective To explore the roles of serum TLR-4, TNF-αand IL-6 in neonates with preterm birth. Methods A total of 120 neonates from neonatology department in the Xingtai People's Hospital were selected and divided into full-term group (n=40), premature rupture of fetal membranes (n=40) and idiopathic preterm group (n=40) based on the gestational age. The peripheral venous blood was collected within 30 minutes when the infants were born, and the supernatant was reserved after centrifuged. The levels of serum TLR-4, TNF-αand IL-6 were detected by enzyme-linked immunosorbent assay. Results The levels of TLR-4, TNF-αand IL-6 in idiopathic preterm and premature rupture of fetal membranes were signiifcantly higher than that in full-term group and showed positive correlation. Conclusion Cytokines TLR-4, TNF-αand IL-6 maybe closely related to the preterm birth.

Exosomes, as a kind of extracellular vesicles generated by inward budding of the endosomes to form multi-vesicular bodies (MVBs), are secreted into the extracellular milieu and the systemic circulation thereafter. By endocytosis, direct fusion or receptor-ligand interactions, exosomes can interact with receptor cells and involve in various pathophysiological processes. Accumulating evidence have indicated that exosomes may play crucial roles in the pathogenesis of many neurodegenerative diseases including Parkinson's disease (PD), Huntington's disease (HD), Alzheimer disease (AD) and amyotrophic lateral sclerosis (ALS). In this paper, the roles of exosomes in the pathogenesis, diagnosis and treatment of PD and ALS are reviewed.

Objective To elucidate the malnutrition in patients with hospital-acquired acute kidney injury(AKI), and to examine the association betweensubjective global assessment (SGA) and prognosis.Methods Adult patients with hospital-acquired AKI were prospectively enrolled in this cohort study.Nutritional evaluations, including SGA, anthropometric and serum nutritional markers were conducted at enrollment.Overall survival at 90 days among different SGA scores was analyzed using Kaplan-Meier methods, and differences were tested using the log-rank test.The Cox model was used to analyze the relationship between SGA scores and all-cause mortality after adjusting for confounders.Results A total of 170 patients were enrolled.The prevalence of moderate malnutrition(SGA B) and severe malnutrition(SGA C) was 51.8％ and 22.9％ respectively, while patients with normal nutrition(SGA A) accounted for 25.3％.After 90 days follow-up, all-cause mortality was 9.8％ in SGA A group, 34.9％ in SGA B group and 56.8％inSGACgrouprespectively. Afteradjustingforage,sex,dialysis,ventilation, hemoglobin, platelets and bilirubin, the hazard ratio(HR) of 90 days all-cause mortality was 4.0(95％ CI 1.42-11.22, P=0.008) in malnutrition group (SGA B group and SGA C group) compared with SGA A group.The Kaplan-Meier curve also revealed that the worse the SGA score was, the lower the cumulative survival became (P＜0.01).Conclusion SGA score is an independent risk factor for all-cause mortality within 90 days in patients with hospital-acquired acute kidney injury.
