Objective To explore the detection methods for cognitive dysfunction of the major depression in Elderly and analyze their clinical significance.Methods Using matched-pairs study,42 patients with seniie de- pressive disorders(experimental group)and 42 normal aged people(control group)were examined with auditory e- voked potential P300(event related potential,ERP-P300)and SECF,respectively.Results It was found that the scores with registration,span,recall,classification and total score of the subjects in the experimental group were sig- nificantly lower than those in the control group(P

Aim To investigate the analgesic effect of tetrahydropalmatine on Cav1 . 2 expression in the dorsal root ganglion ( DRG) of mice with sciatic nerve chronic constriction injury ( CCI ) -induced neuropathic pain. Methods Forty male C57 BL/6 mice were randomly divided into 5 groups ( n =5 ): sham group ( group S) , CCI group ( group C ) and L-THP group ( group L) . Steady mice models of neuropathic pain were es-tablished by inducing CCI of sciatic nerve. According to development of neuropathic pain in mice, L group was divided into induction period, induction with ma-intenance period and long-term low-dose group. The mice were intraperitoneally administered with 45 mg · kg-1 tetrahydropalmatine in induction ( day 0~5 ) , in-duction with maintenance ( day 0~5 , 14~19 ) period of neuropathic pain state. From the instant after opera-tion, 15 mg · kg-1 tetrahydropalmatine was injected into the long-term low-dose group once per day for 19 days. Then, the behavior changes of mice were moni-tored. Moreover, the threshold of mechanical and ther-mal stimuli was tested. In addition, the expression of Cav1 . 2 protein was detected by Western blot and im-munohistochemical staining. Results The lowest ex-pression of Cav1 . 2 was observed in group C and the highest expression level of Cav1 . 2 was found in group S. Cav1. 2 expression was significantly up-regulated in induction period group, induction with maintenance period group and long-term low-dose group ( P<0. 05 , P<0. 01). Compared with group C, high dose of tet-rahydropalmatine in induction period group, induction with maintenance period group and long-term low-dose group showed reduced mechanical allodynia and ther-mal hyperalgesia induced by nerve injury ( P <0. 05 , P<0. 01). Meanwhile, high dose of tetrahydropalma-tine significantly relieved the mechanical allodynia in induction period group, induction with maintenance period group and thermal hyperalgesia in maintenance period group (P<0. 05). However, there was no ob-vious effect on mechanical allodynia and thermal hyper-algesia induced by nerve injury ( P >0. 05 ) in long-term low-dose group. Conclusions High dose of tet-rahydropalmatine in induction period group, induction with maintenance period group and low-dose among the whole experiment process obviously relieves the neuro-pathic pain induced by nerve injury. The analgesic effect of tetrahydropalmatine on neuropathic pain may be due to the increased expression of Cav1 . 2 protein in DRG neurons.

The study was aimed to investigate the different prognosis of acute myeloid leukemia (AML) with inv (16). A 13-year-old patient diagnosed as M4Eo presenting with bulky lymphadenopathy was reported, the curative process of patients was presented and the related issues were discussed. The karyotype and inv (16) were detected by conventional cytogeneties and fluorescence in situ hybridization (FISH), respectively, the immunophenotype was detected by flow cytometry. The results showed that conventional cytogenetics and FISH analysis revealed inv (16). Induction therapy included idarubicin and cytarabine. After complete remission, patient received consolidation theray containing high-dose cytarabine (HDAC). FISH analysis revealed poor response of patient to HDAC. It is concluded that bulky lymphadenopathy in AML with inv (16) may be a negative prognostic sign. FISH for inv (16) is specific and constitutes an reliable tool to be used for diagnosis and minimal residual disease (MRD).

HSP90 is widely expressed in cells with the main function in assisting the maturation of other proteins that are called clients. Many clients play critical roles in the occurrence and development of cancer. Inhibition of HSP90 can lead to degradation of the oncogenic proteins, and result in potent anti-cancer effects. HSP90-HOP interaction is critical for the chaperone function of HSP90, thereby disruption of the HSP90-HOP interaction is a novel strategy in the inhibition of HSP90. Based on the technology of homogeneous time-resolved fluorescence (HTRF), we developed a new assay for the identification of new inhibitors of HSP90-HOP interaction. This method was evaluated in the study of the HSP90-HOP inhibition activity of the pentapeptide MEEVD from HSP90 C-terminal and its derivatives. This study can provide a basis for the screening and discovery of novel HSP90-HOP disruptors.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.

Chaetocin is a natural metabolite product with various biological activities and pharmacological functions isolated from Chaetomium species fungi belonging to the thiodiketopyrazines. Numerous studies have demonstrated a wide range of antitumor activities of chaetocin in vitro and in vivo. Several studies have demonstrated that chaetocin sup?presses the growth and proliferation of various tumour cells by regulating multiple signalling pathways related to tumour initiation and progression, inducing cancer cell apoptosis (intrinsic and extrinsic), enhancing autophagy, inducing cell cycle arrest, as well as inhibiting tumour angiogenesis, invasion and migration. The antitumor effects and molecular mechanisms of chaetocin are reviewed and analysed in this paper, and the prospective applications of chaetocin in cancer prevention and therapy are also discussed. Our review provides the theoretical basis for exploiting the clinical applica?tion of chaetocin in cancer treatment.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.

ObjectiveTo analyze the clinical characteristics of brucellosis patients from two tertiary hospitals in epidemic and non-epidemic areas. MethodsThe clinical data of 67 brucellosis patients hospitalized in The Affiliated Kashi Hospital of Sun Yat-sen University （Kashi， 53） and The Third Affiliated Hospital of Sun Yat-sen University （Guangzhou， 14） from January 2019 to December 2019 were retrospectively reviewed， including demographic data， medical history， symptoms， signs， laboratory tests and treatment， and the differences between the two groups were compared. ResultsThere were 23 patients in Kashi and 11 patients in Guangzhou with definite epidemiological history， respectively （P = 0.019）. Fever， fatigue and arthralgia were the most common symptoms of brucellosis. In addition to anorexia， the onset symptoms of patients in the two hospitals were roughly the same. The incidence of fever， muscle pain and fever peak was similar， but the symptoms of hyperhidrosis， fatigue， arthralgia and rash in Kashi were more common in Guangzhou. There were cases of hepatosplenomegaly in both hospitals， but there was no obvious superficial lymphedema. Complications occurred in 39（73.6%） and 11（78.6%） patients in Kashi and Guangzhou， respectively， with no statistical difference （P =0.971）， and hepatitis and bone damage were the most common. The incidence of spondylitis （P =0.042） and neurodegenerative brucellosis （P =0.041） in Guangzhou was higher than that in Kashi， and there was no significant difference in other complications. Of the patients in Kashi， 7.5 % were treated with single antibiotics， and 59.7 % were with dual therapy， which were higher than those in Guangzhou （0， 50.0 %）. The proportion of the triple scheme in Guangzhou was higher than that of Kashi （50.0 % vs. 11.3 %）. ConclusionsThe clinical characteristics of brucellosis in different regions are generally similar， but there are some differences in epidemiological history， symptoms， complications and treatment options. The characteristics of local cases should be concerned in clinical practice to reduce misdiagnosis of brucellosis.
