ABSTRACT

Objective:To explore any effect of the single- and dual-task treadmill training on the functioning of children with bilateral spastic cerebral palsy.Methods:Fifty children with bilateral spastic cerebral palsy were randomly divided into a single-task treadmill training group (the control group, n=25) and a dual-task treadmill training group (the observation group, n=25). All of the children also received routine rehabilitation training, and the control and observation groups also conducted single- and dual-task treadmill training in addition to the routine rehabilitation training, respectively. Before and after 2 months of treatment, each child′s gross motor functioning was quantified using sections D (standing) and E (walking, running and jumping) of the Gross Motor Function Measurement-88 (GMFM-88) instrument. Balance was quantified using the Pediatric Balance Scale (PBS) and walking mobility was quantified using a 1 minute walking test (1MWT). Modified and dual task Timed Up and Go (mTUG) tests and dual-task effects (DTE) tests were also administered. Results:There were no significant differences in average test scores between the two groups before the treatment. After the treatment significant improvement was observed in both groups. There was no significant difference between the two groups in terms of average GMFM-88, PBS and 1MWT scores, but significantly greater improvement was observed in the average dual-task mTUG and DTE results of the observation group.Conclusion:Both single- and dual-task treadmill training are effective supplements to routine rehabilitation training for children with bilateral spastic cerebral palsy. Dual-task treadmill training is more effective than the single-task version.

ABSTRACT

Clinical data of 3 pregnant women with primary hyperparathyroidism admitted in Jinan Maternal and Child Health Hospital from 2013 to 2021 were retrospectively reviewed. Hyperparathyroidism was diagnosed during pregnancy in all 3 cases. The clinical manifestations were non-specific, such as nausea, vomiting, anorexia, and fatigue. Patients also had gallbladder stones (1 case), gallbladder polyps (1 case), and renal parenchyma changes (2 cases). The hypercalcemia crisis occurred in all 3 cases, the blood Ca 2+ levels were 4.11 mmol/L, 2.92-3.82 mmol/L and 3.49-4.10 mmol/L, respectively; and preeclampsia developed in 2 cases. Sudden death occurred in case 1 who did not receive effective treatment during pregnancy; blood calcium was well controlled during pregnancy in case 2, and her neonate had hypocalcemia with good prognosis; case 3 underwent surgical treatment in early pregnancy, and then had missed abortion. Pathological examination revealed parathyroid tumors in all 3 cases.

ABSTRACT

BACKGROUND@#Imatinib mesylate (IM) resistance is an emerging problem for chronic myeloid leukemia (CML). Previous studies found that connexin 43 (Cx43) deficiency in the hematopoietic microenvironment (HM) protects minimal residual disease (MRD), but the mechanism remains unknown.@*METHODS@#Immunohistochemistry assays were employed to compare the expression of Cx43 and hypoxia-inducible factor 1α (HIF-1α) in bone marrow (BM) biopsies of CML patients and healthy donors. A coculture system of K562 cells and several Cx43-modified bone marrow stromal cells (BMSCs) was established under IM treatment. Proliferation, cell cycle, apoptosis, and other indicators of K562 cells in different groups were detected to investigate the function and possible mechanism of Cx43. We assessed the Ca 2+ -related pathway by Western blotting. Tumor-bearing models were also established to validate the causal role of Cx43 in reversing IM resistance.@*RESULTS@#Low levels of Cx43 in BMs were observed in CML patients, and Cx43 expression was negatively correlated with HIF-1α. We also observed that K562 cells cocultured with BMSCs transfected with adenovirus-short hairpin RNA of Cx43 (BMSCs-shCx43) had a lower apoptosis rate and that their cell cycle was blocked in G0/G1 phase, while the result was the opposite in the Cx43-overexpression setting. Cx43 mediates gap junction intercellular communication (GJIC) through direct contact, and Ca 2+ is the key factor mediating the downstream apoptotic pathway. In animal experiments, mice bearing K562, and BMSCs-Cx43 had the smallest tumor volume and spleen, which was consistent with the in vitro experiments.@*CONCLUSIONS@#Cx43 deficiency exists in CML patients, promoting the generation of MRD and inducing drug resistance. Enhancing Cx43 expression and GJIC function in the HM may be a novel strategy to reverse drug resistance and promote IM efficacy.

ABSTRACT

Radiotherapy is the most common treatment for nasopharyngeal carcinoma, and the radiotherapy technique is essential for the prognosis of nasopharyngeal carcinoma. Due to the complexity of the structure of the intensity-modulated device and the accuracy of the clinical requirements of radiotherapy, it is inevitable that higher requirements will be imposed on the process of intensity-modulated radiotherapy. Currently, gaps exist in the radiotherapy equipment and personnel qualification among radiotherapy units, and thus the homogenization in the radiotherapy remains to be strengthened in China. With the application of radiotherapy information management system, digital medicine and artificial intelligence technologies in the field of radiotherapy, the original process fails to meet the application needs of the new precise radiotherapy technology. Therefore, this process is designed based on the existing radiotherapy procedures for nasopharyngeal carcinoma in combination with the latest developments in the field of radiotherapy, aiming to establish a novel standard process recommendation, ensuring the standardization and homogenization of radiotherapy and achieve the individualized intensity-modulated radiotherapy for nasopharyngeal carcinoma patients.

ABSTRACT

OBJECTIVE:To observe the clinical effect and safety of recombinant human brain natriuretic peptide (rhBNP) combined with levosimendan in the treatment of acute decompensated heart failure (ADHF)complicated with renal insufficiency. METHODS:A total of 156 patients with ADHF complicated with renal insufficiency admitted to the Dept. of Cardiology in the Affiliated Hospital of Southwest Medical University during Jan.-Dec. 2019 were randomly divided into rhBNP group ,levosimendan group and combination group ,with 52 patients in each group. All patients received rountine treatment. On this basis ,rhBNP group was given rhBNP for injection [after 1.5 μg/kg intravenous pulse injection,intravenous dripping for 24 h with 0.007 5 μg(/ kg· min)];leosimendan group was given Leosimendan injection 12.5 mg [intravenous dripping for 1 h with 6-12 μg(/ kg·min),then intravenous dripping for 23 h with 0.1 μg(/ kg·min)]. Combination group received drug combination according to the administration method of single drug group. Three groups received treatment for consecutive 7 d. Cardiac function indexes [heart rate (HR),left ventricular ejection fraction (LVEF),left ventricular end-diastolic diameter (LVEDD)],mean arterial pressure (MAP),pulmonary capillary pressure (PCWP),renal function indexes [estimated glomerular filtration rate (eGFR),serum creatinine (Scr)],serum levels of cystatin C (Cys-c)and amino-terminal brain natriuretic peptide precursor (NT-proBNP)were observed in 3 groups before and after treatment. Clinical efficacy and the occurrence of ADR were recorded. RESULTS :Three cases withdrew from the study in rhBNP group and 1 case in levosimendan group ;152 cases completed the study. Before treatment ,there was no statistical significance in cardiac function indexes ,MAP,PCMP,renal function indexes or serum levels of Cys-C and NT-proBNP among 3 groups(P>0.05). After treatment ,the HP ,MAP,PCWP and serum level of NT-proBNP in 3 group as well as serum level of Cys-C in combination group were decreased significantly (P<0.05);the LVEF in 3 group as well as the eGFR and Scr level in levosimendan group and combination group were significantly increased (P<0.05),compared with before treatment ;above indexes of combination group were significantly better than those of rhBNP group and levosimendan group (P<0.05). Total effective rate of combination group was 94.23% ,which was significantly higher than those of rhBNP group (77.55%)and levosimendan group (76.47%)(P<0.05). There was no significant difference in the incidence of ADR among 3 groups(P> 0.05). CONCLUSIONS :rhBNP combined with levosimendan in the treatment of ADHF complicated with renal insufficiency can significantly increase the clinical efficacy ,and improve cardiac and renal function but don ’t increase the incidence of ADR.

ABSTRACT

Objective To evaluate the clinical outcomes and feasibility of multi-modality adjuvant chemotherapy and radiation, which was conducted as postoperative chemotherapy, radiation, and consolidation chemotherapy (CRC) mode for the treatment of advanced endometrial cancer. Methods A retrospective analysis of 124 patients with International Federation of Gynecology and Obstetrics (FIGO) stages Ⅲ and Ⅳ endometrial cancer from Jan. 2004 to Oct. 2012 was conducted in Peking University People′s Hospital and Beijing Obstetrics and Gynecology Hospital. Inclusion criteria were comprehensive staging procedure including hysterectomy, bilateral salpingo-oophorectomy, and (or) selective pelvic aortic lymphadenectomy, and treatment with adjuvant chemotherapy and (or) radiation. The average age of these patients was (55.9 ± 8.4) years old (range from 23 to 79 years old). According to different postoperative adjuvant treatment modes, the patients were divided into CRC group, chemotherapy-radiotherapy (CR) group and single chemotherapy (C) group. The survival and side effects of the three groups were compared. Results (1) One hundred and twenty-four patients with advanced stage endometrial cancer were identified and received postoperative adjuvant therapies.Sixty-one (49.2%, 61/124) cases of them received postoperative CRC fashion, 19 (15.3%, 19/124) received postoperative CR and 44 (35.5%, 44/124) cases received C. The age, stage, grade and type of surgery of the three groups were not significantly different (all P>0.05);while, the pathology, chemotherapy cycles and chemotherapy regimens differed significantly (all P<0.05). (2) The progression-free survivals (PFS) of the patients with CRC, CR, and C group were (121±7), (68± 15), and (100±11) months, respectively. The 3-year PFS rates were 87.9%, 43.7%, and 61.4%, respectively. The 5-year PFS rates were 82.2%, 36.4%, and 61.4%, respectively. The above indicators were significantly higher in the CRC group than in the CR group (all P<0.01), and there was no difference between the CRC group and the C group (P=0.037). The overall survival (OS) of patients with CRC, CR, and C group were (128 ± 6), (80 ± 12), and (99 ± 10) months, respectively. The 3-year OS rates were 87.8%, 72.4%, and 67.1%, the 5-year OS rate were 84.2%, 54.3%, and 64.1%, respectively. The above indicators were significantly higher in the CRC group than those in the CR group and C group (all P<0.01). (3) There was no difference in the frequency of adverse effects either chemotherapy, such as severe bone suppression or radiotherapy;hepatotoxicity,blood transfusion, dose modifications;or cycle delays between the CRC, CR and C group (all P>0.05). (4) In the univariate analysis shown that, stage, the fashion of postoperative adjuvant therapy and type of surgery were risk factors for tumor progression in patients with advanced endometrial cancer (P<0.05). After adjusted for FIGO stage and type of surgery, the tumor progression hazard ratio (HR) was 3.931 (95%CI:1.734-8.914, P=0.001) for the CR group and 2.188 (95%CI:1.010-4.741, P=0.047) for the C group, compared to the CRC group. Conclusion Sequential CRC delivered in a"sandwich"fashion for the treatment in advanced endometrial cancer could significantly improve the 3-year and 5-year OS rates and have a similar adverse effect profile compared with other sequencing modalities.

ABSTRACT

Mitochondrial diseases are maternally inherited heterogeneous disorders that are primarily caused by mitochondrial DNA (mtDNA) mutations. Depending on the ratio of mutant to wild-type mtDNA, known as heteroplasmy, mitochondrial defects can result in a wide spectrum of clinical manifestations. Mitochondria-targeted endonucleases provide an alternative avenue for treating mitochondrial disorders via targeted destruction of the mutant mtDNA and induction of heteroplasmic shifting. Here, we generated mitochondrial disease patient-specific induced pluripotent stem cells (MiPSCs) that harbored a high proportion of m.3243A>G mtDNA mutations and caused mitochondrial encephalomyopathy and stroke-like episodes (MELAS). We engineered mitochondrial-targeted transcription activator-like effector nucleases (mitoTALENs) and successfully eliminated the m.3243A>G mutation in MiPSCs. Off-target mutagenesis was not detected in the targeted MiPSC clones. Utilizing a dual fluorescence iPSC reporter cell line expressing a 3243G mutant mtDNA sequence in the nuclear genome, mitoTALENs displayed a significantly limited ability to target the nuclear genome compared with nuclear-localized TALENs. Moreover, genetically rescued MiPSCs displayed normal mitochondrial respiration and energy production. Moreover, neuronal progenitor cells differentiated from the rescued MiPSCs also demonstrated normal metabolic profiles. Furthermore, we successfully achieved reduction in the human m.3243A>G mtDNA mutation in porcine oocytes via injection of mitoTALEN mRNA. Our study shows the great potential for using mitoTALENs for specific targeting of mutant mtDNA both in iPSCs and mammalian oocytes, which not only provides a new avenue for studying mitochondrial biology and disease but also suggests a potential therapeutic approach for the treatment of mitochondrial disease, as well as the prevention of germline transmission of mutant mtDNA.

ABSTRACT

Objective:To understand the status of supervision of mental health service industry in Shanghai, and to provide reference for further strengthening the construction of mental health service system in Shanghai. Methods: In Shanghai, 107 mental health service agencies (including psychiatric institutions, non-specialist medical institutions, non-specialist enterprise and public institutions, social institutions) were selected from Shanghai psychological service industry association. The survey was conducted with the Questionnaire on Current Situation of Mental Health Professional Service Agencies in Shanghai (agency survey), including the "relevant information of agency" and the "management of the agency in the field of mental health services"(whether the agency had supervision requirements on the mental health service personnel, whether the agency organized supervision, the source of supervisors and payment method), and the Questionnaire on Current Situation of Mental Health Service Professionals in Shanghai (professional survey), including "basic information on demography "and" psychological professional work" (the number of hours of supervision in 2015, the cost of supervision, and the form of supervision and payment method). These two parts of questionnaire were selected and analyzed. Results: Agency survey results showed that 80% of non-specialist enterprises had no supervision requirements for mental health service personnel, supervisor in non-specialist medical institutions were mainly from psychiatric institution (52.9%). The cost of supervision in most psychiatric institutions was paid by the agency (39.1%) and the cost of supervision in most public institutions was paid by professional (37%). The professional institutions under the jurisdiction of other departments within the unit required less supervision of the professional staff than the independent institutions (P < 0.001). Professional survey results showed that the number of supervision hours of mental health service professional in social institutions was more than that in the other three types of institutions (P <0.001), of which 47.9% chosen to pay the cost of supervision by themselves. The proportion of their own payment in social institutions was higher than that in the other three types of institutions (P <0.001). Conclusion:The social institutions in Shanghai have the best supervision of social institutions, followed by the supervision of the medical institutions. The supervision of non-medical enterprises and their personnel needs to be improved.

ABSTRACT

Objective To investigate the effect of rhynchophylline on mRNA expression of excitatory amino acid transporter 2 (EAAT2 ) and N-methyl-D-aspartic acid receptor 2B (NR2B) after astrocyte oxygen-glucose deprivation. Methods The subcultured third generation astrocytes from the hippocampus were inoculated into 6-well plates, and they were divided into blank control group, hypoxia-ischemia group,low-dose rhynchophylline group (0. 02 mg/ml) and high-dose rhynchophylline group (0. 2 mg/ml) after the cells were attached to the wall and grew out protrusion. The total RNAs in each group were extracted.Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression levels of EAAT2 and NR2B mRNA in astrocytes of each group. Results Compared with the blank control group, the expression levels of NR2B and EAAT2 mRNA in astrocytes of the ischemia-hypoxia group were significantly higher (all P < 0. 05 ). The expression levels of NR2B and EAAT2 mRNA in the low-dose rhynchophylline group were lower than those in ischemia-hypoxia group, but there was no significant difference. The expression levels of NR2B and EAAT2 mRNA in the high-dose rhynchophylline group were significantly lower than the ischemia-hypoxia group and the low-dose rhynchophylline group (all P < 0. 05).Conclusion The expression of EAAT2 and NR2B mRNA in astrocytes of hippocampus cultured in vitro was significantly increased after ischemia and hypoxia, and rhynchophylline intervention could significantly reduce its expression in a concentration dependent manner.

ABSTRACT

OBJECTIVE: To observe the changes of chest imaging and prognosis in pneumoconiosis patients in tin smelting workers. METHODS: Ten pneumoconiosis patients working with tin smelting were examined by chest X-ray,computed tomography( CT) photography and dynamic observation on pulmonary imaging to analyze their characteristics and prognosis. RESULTS: There were mild clinical manifestations and no tuberculosis in these 10 cases of tin smelting pneumoconiosis patients. There was no obvious change on the pulmonary ventilation function change. The high k V X-ray chest observation results showed that the circular shadow was the primary small shadow of the two lungs,that were mostly distributed in the medium and upper lung zones of both lungs. In most cases,we found lung texture distortion,deformation or increase,blurred,hilar shadow increased thickening,lymph node calcification,individualized eggshell. There was no pleural changes and emphysema changes. There was no significant change found in 5-10 years of dynamic observation except for 1 case of increased small shadow. The chest CT examination in 2011 showed 2-5 mm nodular shadows. Among them,we found 7 cases of small nodules from the upper lobe evenly distributed to the middle of the lobe,the lower back lobe of the lungs,lower basal ganglia lesions decreased,lesions were diffuse distribution of the whole lung,and the small nodules in 3 cases. Interval lobular thickening at varying degrees were found in 5 cases,lobular central or apoptotic pulmonary emphysema were found in 4 cases,and 1 case of pulmonary bullae formation was found. The results of chest CT examination in 2016 showed 2 cases of diffuse pulmonary nodules,3 cases of thickening of lobular septum and 2 cases of pulmonary emphysema compared with the CT result in 2011. CONCLUSION: There was no obvious lung small shadow absorption found in tin smelting pneumoconiosis patients after 5 to 10 years of X-ray dynamic observation,and progress of lesions could be seen. CT examination is helpful for follow-up observation in tin smelting pneumoconiosis.

ABSTRACT

Objective To study the effects and mechanism of calycosin on oxidative stress andβ-cell apoptosis induced by streptozotocin (STZ). Methods RIN-m5F cells were divided into 5 groups:control group, STZ group, STZⅠgroup, STZⅡgroup and STZⅢgroup. The control group did not receive any treatment, while streptozotocin was added to the final concentration of 10 mmol/L in STZ group, STZⅠgroup, STZⅡgroup and STZⅢgroup. After the incubation with STZ for 6 h, calycosin was added to a final concentration of 10, 50 and 100 μmol/L in STZⅠgroup, STZⅡgroup and STZⅢgroup respectively. The cell viability and apoptosis was detected by CCK-8, LDH, caspase 3 and Tunel assay. The intracellular oxidative stress was measured using mitochondrial membrane potential, DCFH-DA, SOD activity and malondialdehyde levels assay. RIN-m5F cells were divided into control group, calycosinⅠgroup, calycosinⅡgroup and calycosinⅢgroup, which were treated with different concentrations (0,10, 50 and 100 μmol/L, respectively) of calycosin. The expression of NF-E2-related factor 2(Nrf2) in RIN- m5F cells was detected by Western blot. The translocation of Nrf2 was detected by immunofluorescence. In RIN-m5F cells were divided intoⅢgroup andⅣgroup,Ⅳgroup was pre-treated with protein kinase C(PKC) inhibitor. The effects of calycosin on Nrf2 translocation, oxidative stress and apoptosis were also observed. Results STZ could induce the accumulation of reactive oxygen species and apoptosis in RIN-m5F cells. Calycosin did not affect normal RIN-m5F cells, whereas it reduced the oxidative stress and apoptosis induced by STZ in a dose-dependent manner. The expression of Nrf2 in RIN-m5F cells was not affected by calycosin, whereas it promoted the translocation of Nrf2 into nucleus. The ability of calycosin promoting Nrf2 translocation was decreased after PKC inhibitor treatment, and PKC inhibitor could also significantly attenuate the anti-oxidant and anti-apoptotic ability of calycosin. Conclusions This study shows that calycosin may play an anti-oxidative and anti-apoptotic role by activating PKC to promote Nrf2 translocation, which is expected to be used as a new clinical drug for the prevention and treatment of diabetes mellitus.

ABSTRACT

Objective To investigate the effect of Goserelin in protection of the ovarian function of pre-menopausal breast cancer patients. Methods Eighty premenopausal patients with breast cancer randomly divided equally into study group and control group. The two groups were compared in terms of the menstrual status and the levels of E2,FSH,LH before and after chemotherapy. Results The menstrual recovery rates of the study group and the control group were 90% and 57.5%,respectively ,with statistically significant difference between them (P = 0.018). In the study group,the serum E2 decreased gradually to the postmenopausal level,and the serum levels of FSH and LH were also significantly decreased during the treatment. While in the control group ,the E2 levels gradually decreased ,but the levels of FSH and LH significantly increased during the chemotherapy. Conclusions Goserelin can effectively prevent the injury of ovarian function caused by chemotherapy.
