ABSTRACT
Objective:To assess the clinical effect of retrograde elastic stable intramedullary nailing(ESIN) in distal humerus metaphysis-diaphyseal junction fractures in children.Methods:A total of 14 cases of children with distal humerus metaphysis-diaphyseal junction fractures treated by retrograde ESIN in Children′s Hospital of Nanjing Medical University from January 2016 to December 2018 were retrospectively analyzed.There were 9 males and 5 females, aged 3.0-13.2 years old(median: 6.4 years old). Nine cases had fractures on the left side and 5 cases on the right side.Two prebent ESINs were inserted into the proximal humerus metaphysis through the humerus marrow cavity from medial and lateral sides of the distal humerus respectively after the closed/open reduction of fractures.After surgery, the shoulder abductor stent or long arm plaster was used for fixation post-operatively.X - ray examination was performed at regular post-operative follow-up.The stability of internal fixation was analyzed by measuring the Baumann angle and checking whether humeral anterior lines passed through capitulum humeri in lateral radiographs immediately after the surgery and at the last follow-up.Meanwhile, efficacy was evaluated according to Flynn functional evaluation criteria.Results:All the 14 patients in this group were followed up for 10-27 months after the operation, with an average of 18.4 months.The Baumann angle was within the normal range at both the end of the operation and the last follow-up, and no significant difference was observed.Lateral radiographs showed humeral anterior lines passed through the capitulum humeri.According to Flynn functional scores, there were 13 excellent cases and 1 good case.No wound infection, intramedullary nailing displacement, Volkmann contracture, cubital varus deformity, or iatrogenic nerve injury occurred in any of the children.Conclusion:Retrograde ESIN technique is a safe and reliable treatment for children with distal humerus metaphysis-diaphyseal junction fractures.

Objective Apoptosis was induced by oxidative stress in nerve cells after cerebral ischemia. It further breaks the dy-namic balance of mitochondrial division of fusion. This study aimed to investigate the effect of butylphthalide combined with edaravone treat-ment on the dynamic change of Drp1 and Mfn2 in rats with focal cere-bral ischemia cells and its protection mechanism. Methods 96 rats were divided into 4 groups according to random number table. The 4 groups were ischemia group,butylphthalide group,edaravone group and butylphthalide combined with edaravone groups(combine group),each group divided into three subgroups(3 d,7 d,14 d). Longa-Zea suppository method is adopted to establish the middle cerebral artery occlusion(MCAO)model.Butylphthalide group,edar-avone group and combine group were injected butylphthalide(0.4 g/kg)and/or edaravone(10 mL/kg)peritoneally 2 hours before surgery and 1 day after surgery. The same volume of isotonic saline was given at the same time of the other 3 groups in ischemia group. The cerebral cortex of the left ischemic region was obtained at the day 3,7,14. The evaluation of the curative effect was evaluated with neurological function score.HE staining was used to observe the cerebral cortex neuron morphological structure,protein and mRNA lev-el of Drp1 and Mfn2 was measured by western blot and RT-PCR. Results At the day 3,7,and 14,the neurological function score was higher in ischemia group than the other 3 groups(P<0.05). Compared with the combine group at day 3,7,and 14[(1.06± 0.18),(0.82±0.13),(0.57±0.10)],the neurological function score was elevated in butylphthalide group[(2.02±0.18),(1.23± 0.13),(0.86±0.10)]and edaravone group[(2.08±0.17),(1.23±0.13),(0.85±0.12)](P<0.05). At the same time point,com-pared with the ischemia group,Drp1 protein and mRNA levels were lower in the other 3 groups(P < 0.05)while Mfn2 protein and mRNA levels were elevated(P<0.05). Compared with the butylphthalide group and edaravone group,Drp1 protein and mRNA levels were lower in combine group(P<0.05)while Mfn2 protein and mRNA levels were elevated(P<0.05). Conclusion The protective effect of edaravone combined with butylphthalide is better than single use. Its mechanism may be related to the removing of oxygen free radicals and reducing oxidative stress by edaravone,and the protection of the mitochondria by butylphthalide.
ABSTRACT
Objective To dig the correlation between genes and four TCM constitutions (phlegm-dampness, blood stasis, allergy, and dampness-heat); To analyze microscopic mechanism of constitution formed and constitution-disease correlation; To provide biological basis for TCM constitution classification and constitution-disease correlation theory. Methods Literature about TCM constitutions and gene expressions in CNKI and Wanfang Database were retrieved by computers from the establishment of database to 31, December 2016. Differentially expressed genes of four TCM constitutions were collected, and DAVID database was used for enrichment analysis, including gene tissue enrichment analysis, disease analysis, GO analysis, and pathway analysis. The results of DAVID database analysis were downloaded and analyzed. Results Four TCM constitutions had differences in gene level, and each constitution had the specificity in significantly enriched gene function, activity, pathways, related diseases, and expression locations. Different patterns of gene expression led to the constitution differences in disease susceptibility and tendency. Conclusion The essence of TCM constitution formation is the change of gene expression patterns, and the pathological changes are also caused by the change.
ABSTRACT
Objective@#To investigate the clinicopathological characteristics, diagnosis, and treatment of primary seminal vesicle adenocarcinoma (SVAC).@*METHODS@#We analyzed the clinical data and clinicopathological characteristics of 4 cases of primary SVAC treated in the Department of Urology of the Second Hospital of Tianjin Medical University and reviewed relevant literature.@*RESULTS@#All the 4 patients were treated by open radical resection of the seminal vesicle and prostate and pathologically diagnosed with SVAC. Preoperative prostatic biopsy had shown 1 of the cases to be negative, while preoperative CT and transrectal ultrasound had revealed a huge pelvic cystic neoplasm in another patient. Immunohistochemistry manifested that the 4 cases were all negative for prostate-specific antigen (PSA), prostatic acid phosphatase (PAP), and cytokeratin 20 (CK20), but positive for cancer antigen 125 (CA125) and CK7. All the patients recovered smoothly after surgery and experienced no recurrence or metastasis during 154, 41, 20, and 12 months of follow-up.@*CONCLUSIONS@#Primary seminal vesicle carcinoma is extremely rare and presents in an advanced stage. Immunohistochemistry plays a valuable role in its differential diagnosis. Various combinations of radical surgery, radiotherapy, androgen-deprivation therapy, and chemotherapy are recommended for the treatment of the disease.

The present study aimed to improve the processing of data acquired from laser speckle contrast imaging (LSCI) to provide a standardization method to explore changes in regional cerebral blood flow (rCBF) and to determine the correlations among rCBF, cerebral ischemic lesion volume and microvascular density over time in a focal ischemic region. C57BL/6J mice were subjected to focal photothrombotic (PT) ischemia. rCBF was measured using LSCI at different time points before and after PT ischemia through an intact skull. Standardized rCBF (SrCBF), defined as the ratio of rCBF measured in the ipsilateral region of interest (ROI) to that in the corresponding contralateral region, was calculated to evaluate potential changes. In addition, the volume of the ischemic lesion and the microvascular density were determined using Nissl staining and immunofluorescence, respectively. The relationships among the ischemic lesion volume, microvascular density and SrCBF were analyzed over time. The results showed that the cortical rCBF measured using LSCI following PT ischemia in the C57BL/6J mice gradually increased. Changes in the cerebral ischemic lesion volume were negatively correlated with SrCBF in the ischemic region. Changes in the microvascular density were similar to those observed in SrCBF. Our findings indicate that LSCI is a practical technique for observing changes in murine cortical rCBF without skull opening and for analyzing the relationships among the ischemic lesion volume, microvascular density and SrCBF following focal cerebral ischemia. Preliminary results also suggest that the use of LSCI to observe the formation of collateral circulation is feasible.

Obstructive sleep apnea (OSA) is an independent risk factor for cardiovascular diseases. Aldosterone was reported to be increased in patients with OSA and correlated with OSA severity. Many studies investigated the effect of continuous positive airway pressure (CPAP) therapy on plasma aldosterone concentrations (PAC) in OSA patients. The results, however, were inconsistent. In the present study, we aimed to evaluate the effects of CPAP therapy on PAC by performing a meta-analysis. Literature search was carried out in electronic databases including PubMed/Medline, Cochrane Library, Embase and Web of Science. Eligible full-text articles were identified, and important data were extracted. Pooled analysis was performed using the STATA12.0 and RevMan 5.2. Standardized mean difference (SMD) was calculated to estimate the treatment effects. A total of eight studies involving 219 patients were included for our final analysis. PAC was found unchanged after CPAP treatment in OSA patients (SMD=-0.36, 95% CI:-0.91 to 0.18, Z=1.32, P=0.19). Meanwhile, CPAP therapy showed no impact on PAC (SMD=-0.21, 95% CI:-0.85 to 0.42, Z=0.66, P=0.51) in a separate meta-analysis including 3 randomized controlled trials. In conclusion, the evidence for the use of CPAP therapy to decrease PAC in OSA patients is low, and further studies are still warranted.

ABSTRACT
Induced pluripotent stem cells (iPSCs) can be propagated indefinitely, while maintaining the capacity to differentiate into all cell types in the body except for the extra-embryonic tissues. This iPSC technology not only represents a new way to use individual-specific stem cells for regenerative medicine but also constitutes a novel method to obtain large numbers of disease-specific cells for biomedical research. However, the low efficiency of reprogramming and genomic integration of oncogenes and viral vectors limit the potential application of iPSCs. Chemical-induced reprogramming offers a novel approach to generating iPSCs. In this study, a new combination of small-molecule compounds (SMs) (sodium butyrate, A-83-01, CHIR99021, Y-27632) under conditions of transient folate deprivation was used to generate iPSC. It was found that transient folate deprivation combined with SMs was sufficient to permit reprogramming from mouse embryonic fibroblasts (MEFs) in the presence of transcription factors, Oct4 and Klf4, within 25 days, replacing Sox2 and c-Myc, and accelerated the generation of mouse iPSCs. The resulting cell lines resembled mouse embryonic stem (ES) cells with respect to proliferation rate, morphology, pluripotency-associated markers and gene expressions. Deprivation of folic acid, combined with treating MEFs with SMs, can improve the inducing efficiency of iPSCs and reduce their carcinogenicity and the use of exogenous reprogramming factors.

<p><b>OBJECTIVE</b>To investigate the prognostic influence on long-term overall survival (OS) from treatment with Chinese medicine (CM) and chemotherapy or targeted therapy in advanced non-small-cell lung cancer (NSCLC) patients.</p><p><b>METHODS</b>The clinical data of 206 advanced NSCLC patients who were treated with CM and Western medicine in Beijing Cancer Hospital from April 1999 to July 2013 were retrospectively analyzed. Long-term survivors were defined as OS ≥ 3 years after treatment with CM and chemotherapy. Twenty-eight patients had OS ≥ 3 years, 178 had OS < 3 years, and all clinical data were statistically analyzed with the Cox model. Variables were gender, age, smoking status, performance status (PS) score, pathological type, clinical stage, first-line chemotherapy, targeted therapy, and use of CM. Univariate survival analysis was performed using the Kaplan-Meier method and log-rank sequential inspection. Multivariate survival analysis was used to analyze the meaningful factors of univariate survival analysis with the Cox model.</p><p><b>RESULTS</b>The survival rate of patients with OS ≥ 3 years was 13.6% (28/206). Cox multivariate regression analysis showed that PS score, clinical stage, disease control rate to first-line chemotherapy, and use of CM were independent factors of longterm OS (all <0.05). However, gender, age, smoking, and use of epidermal growth factor receptor tyrosine-kinase inhibitor were not significant (P>0.05).</p><p><b>CONCLUSION</b>PS score, clinical stage, disease control rate to first-line chemotherapy, and use of CM are probably independent prognostic factors for long-term OS in patients with advanced NSCLC.</p>

Objective To investigate the curative effect and feasibility of closed reduction with elastic intramedullary nailing and open reduction with Kirschner wire fixation in treatment of obviously displaced radial neck fractures in children. Methods From July 2006 to December 2007, 18 children with types Ⅱ and Ⅲ O' Brien radical neck fractures were admitted to Nanjing Children' s Hospital. Of all, six children received open reduction and fixation with Kirschner wire and six weeks of cast immobilization; the other 12 children received closed reduction and fixation with elastic intramedullary nail and three weeks of cast immobilization. The children were followed up for mean 12 months to investigate postoperative functional recovery of the elbow joint and presence of complications. Results All children achieved excellent clinical outcomes, without excessive radial bone growth, early closure of radial bone marrow, bone bridge formation or ectopic calcification around the joint. According to Tibone and Stoltz' s clinical evaluation methods, closed reduction with elastic intramedullary nailing had less trauma, faster recovery, fewer complications and better cosmesis than traditional open reduction with Kirschner wire fixation for children with obviously displaced radial neck fractures. Conclusion Closed reduction with elastic intramedullary nailing is a better option for obviously displaced radial neck fractures in children.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the feasibility of membrane protein-based two-dimensional electrophoresis (2-DE) in the investigations of chondrocyte-related diseases and its complementarity with total protein-based 2-DE.</p><p><b>METHODS</b>Knee cartilage samples were obtained to isolate the chondrocytes with type II collagenase/hyaluronidase digestion. The membrane proteins and total proteins were extracted and loaded separately onto PH3.0-10.0 non-linear gel strip for 2-DE analysis.

<p><b>OBJECTIVE</b>To evaluate the efficacy and side effects of combined Chinese drugs and chemotherapy in treating advanced non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>Sixty-three patients with stage III B and IV NSCLC hospitalized from October 2001 to October 2008 were enrolled and assigned to two groups using a randomizing digital table, with 33 patients in the treatment group and 30 in the control group. They were all treated with the Navelbine and Cisplatin (NP) chemotherapy, but to the treatment group the Chinese drugs Shengmai Injection () by intravenous dripping and Gujin Granule () by oral intake were given additionally. The main observation indexes were response rate (RR), median survival time, 1-year survival rate and median time to progression (TTP); secondary observation indexes were side effects and cycles of chemotherapy.</p><p><b>RESULTS</b>Altogether, 61 patients (33 from the treatment group and 28 from the control group) completed the observation and were assessable. RR was 48.5% (16/33) in the treatment group and 32.2% (9/28) in the control group, and the median survival time were 13 months and 9 months, respectively; the difference between the two groups was significant (P=0.0373 and P=0.014 respectively). However, the differences between groups were insignificant in terms of 1-year survival rate [51.5% (17/33) vs 46.4% (13/28), P=0.4042], median TTP (5.95 months vs 4.64 months, P=0.3242), grade III or IV bone marrow inhibition occurrence rate [33.3% (11/33) vs 39.3% (11/28), P=0.3500], and mean cycles of chemotherapy applied (2.94+/-0.94 cycles vs 2.75+/-0.75 cycles, P=0.4100).</p><p><b>CONCLUSION</b>Combined Chinese drugs and chemotherapy can enhance the short-term therapeutic efficacy in the treatment of NSCLC and prolong patients' median survival time, but show no evident impact on TTP.</p>
