Gliomas are the most common primary malignant tumors in the central nervous system，and more than half of them are WHO grade IV glioblastomas. Even if surgery，concurrent chemoradiotherapy and adjuvant chemotherapy were applied，median survival of GBM patients is still only 14.2 months. Immunosuppression is an important feature of malignant glioma. Immunotherapy which reverse immunosuppression may be the most promising way to improve the treatment effect of glioma patients in recent years. This article reviews the recent progress of glioma immunotherapy and the research progress of regulatory T cells（Treg）and glucocorticoid-induced tumor necrosis factor receptor（GITR）in the glioma microenvironment. We hope this article will provides new research ideas for glioma immunotherapy.

PURPOSETraumatic diaphragmatic rupture (TDR) needs early diagnosis and operation. However, the early diagnosis is usually difficult, especially in the patients without diaphragmatic hernia. The objective of this study was to explore the early diagnosis and treatment of TDR.

METHODSData of 256 patients with TDR treated in our department between 1994 and 2013 were analyzed retrospectively regarding to the diagnostic methods, percentage of preoperative judgment, incidence of diaphragmatic hernia, surgical procedures and outcome, etc. Two groups were set up according to the mechanism of injury (blunt or penetrating).

RESULTSOf 256 patients with a mean age of 32.4 years (9-84), 218 were male. The average ISS was 26.9 (13-66); and shock rate was 62.9%. There were 104 blunt injuries and 152 penetrating injuries. Preoperatively diagnostic rate was 90.4% in blunt injuries and 80.3% in penetrating, respectively, P < 0.05. The incidence of diaphragmatic hernia was 94.2% in blunt and 15.1% in penetrating respectively, P < 0.005. Thoracotomy was performed in 62 cases, laparotomy in 153, thoracotomy plus laparotomy in 29, and combined thoraco-laparotomy in 12. Overall mortality rate was 12.5% with the average ISS of 41.8; and it was 21.2% in blunt injuries and 6.6% in penetrating, respectively, P < 0.005. The main causes of death were hemorrhage and sepsis.

CONCLUSIONSDiagnosis of blunt TDR can be easily obtained by radiograph or helical CT scan signs of diaphragmatic hernia. For penetrating TDR without hernia, "offside sign" is helpful as initial assessment. CT scan with coronal/sagittal reconstruction is an accurate technique for diagnosis. All TDR require operation. Penetrating injury has a relatively better prognosis.

OBJECTIVESTo study the difference between gene expressions of high (H0-8910PM) and low (HO-8910) metastatic human ovarian carcinoma cell lines and screen novel associated genes by cDNA microarray.

METHODScDNA retro-transcribed from equal quantities of mRNA derived from high and low metastatic tumor cells or normal ovarian tissues were labeled with Cy5 and Cy3 fluorescein as probes. The mixed probe was hybridized with two pieces of BioDoor 4096 double dot human whole gene chip and scanned with a ScanArray 3000 laser scanner. The acquired image was analyzed by ImaGene 3.0 software.

RESULTSA total of 355 genes with expression levels more than 3 times larger were found by comparing the HO-8910 cell with normal ovarian epithelial cells. A total of 323 genes with expression levels more than 3 times larger in HO-8910PM cells compared to normal ovarian epithelium cells were also detected. A total of 165 genes whose expression levels were more than two times those of HO-8910PM cells compared to their mother cell line (HO-8910) were detected. Twenty-one genes with expression levels > 3 times were found from comparison of these two tumor cell lines.

CONCLUSIONScDNA microarray techniques are effective in screening differential gene expression between two human ovarian cancer cell lines (H0-8910PM; HO-8910) and normal ovarian epithelial cells. These genes may be related to the genesis and development of ovarian carcinoma. Analysis of the human ovarian cancer gene expression profile with cDNA microarray may help in gene diagnosis, treatment and prevention.

Objective To explore the relationship between T lymphocyte subsets and both glioma malignancy and its prognosis, and determine a clinical immunologic index for evaluating preoperative glioma malignancy and its prognosis. Methods The data of 117 inpatients with primary intracranial tumors, including glioma (n=85) and meningioma (n=32), were retrospectively analyzed. Fluorescence-activated cell sorting (FACS) analysis was performed to detect the preoperative contents of T lymphocyte subsets on 32 patients with meningioma and patients with glioma, including 45 high-grade glioma (WHO, grade Ⅲ-Ⅳ) and 40 low-grade glioma (WHO, grade Ⅰ -Ⅱ); and then the differences of their immunologic indexes were analyzed. Based on the detection result of T lymphocyte subsets, patients with glioma were divided into two groups: CD4~+CD8~+<1 and CD4~+CD8~+>1. Follow-up for 3-5 years was performed and the survival difference of these two groups was analyzed. Results Patients with high-grade glioma showed a decreased ratio of CD4~+CD8~+ and an increased value of CD8~+ with significant difference as compared with patients with low-grade glioma (P<0.05); patients with high-grade glioma showed a decreased ratio of CD4~+CD8~+, and an increased value of CD8~+ with statistical significance compared with patients with meningioma (P <0.05); patients with low-grade glioma showed a decreased ratio of CD4~+CD8~+ with statistical significance compared with the patients with meningioma (P<0.05). Patients with glioma showed a decreased ratio of CD4~+CD8~+ and CD4~+, and an increased CD8~+ with statistical significance compared with patients with meningioma (P<0.05). After follow-up for 3-5 years, 48 patients with glioma was found in the CD4~+CD8~+>1 group with 21 death (43.8%) and 31 months as a median survival time; 37 patients with glioma was found in the CD4~+CD8~+<1 group with 23 death (62.2%) and 16 months as a median survival time. The Kaplan-Meier survival curves were analyzed with statistical significance (P<0.05). Conclusion The prognosis is poor in patients with low ratio of CD4~+CD8~+. The preoperative level of T lymphocyte subsets in peripheral blood, correlated to the glioma malignancy, can be considered as an index to evaluate the glioma malignancy and the prognosis in patients with glioma.

Objective To explore whether aggressive treatment of primary focus can benefit nonsmall cell lung cancer(NSCLC)patients with synchronous brain metastasis,and search the appropriate treatment protocols.Methods The clinical data of 19 NSCLC patients with synchronous brain metastasis,received treatment at our Cancer Center from January 2000 to January 2009,were reviewed; their treatments and survival statuses were analyzed.Results Median survival time of these patients was 14.5 months; the 1-year survival rate was 52.6％,and 2-year survival rate was 17.5％.Patients had different survival rates when different treatments were given to the primary focus,and significant difference was noted(x2=10.532,P=0.005); after neurosurgical intervention,patients underwent thoracic operation and chemotherapy(24.9 months)had a significantly longer survival time than those underwent chemotherapy(14.5 months)or palliative therapy(5.4 months,P＜0.05).The survival time of patients with single metastases was 16.3 months,and that of those with multiple metastases was 5.4 months; and significant difference was noted between them(P＜0.05).Conclusion Aggressive therapy including neurosurgical intervention,pulmonary resection and chemotherapy should be recommended for NSCLC patients with synchronous brain metastasis,especially those with single brain metastasis.

Objective: To observe the effect of Pinelliae Rhizoma Praeparatum Cum Alumine polysaccharides(PRPCAP)on airway mucus secretion in rats with allergic asthma, in order to study the material basis of the "macromolecule" component of the polysaccharides as the original medicinal materials. Method: The 60 SPF-grade Wistar rats were induced by intraperitoneal injection of chicken ovalbumin (OVA) and aluminum-magnesium adjuvant, except for the normal control group. The OVA solution was aerosolized to establish a rat model of allergic asthma. After successful modeling, the rats were randomly divided into 5 groups, namely allergic asthma model group, positive drug group (montalurast sodium,5 mg·kg^-1), high-dose PRPCAP group (400 mg·kg^-1), middle-dose PRPCAP group (200 mg·kg^-1) and low-dose PRPCAP group (100 mg·kg^-1). The contents of interleukin-4 (IL-4) and interferon-γ (IFN-γ) in serum and bronchoalveolar lavage fluid (BALF) supernatant were determined by enzyme-linked immunosorbent assay (ELISA), and the count of eosinophils (EOS) was detected by BALF sediment. The histopathological changes were observed by hematoxylin-eosin (HE) staining in lung tissue. The mRNA expression of mucin 5AC (MUC5AC) was detected by Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR). Result: Compared with the normal control group, serum IL-4 level in the allergic asthma model group was significantly increased (P<0.01), IFN-γ level was significantly decreased (P<0.01), and EOS counts in BALF were significantly increased (P<0.01). Compared with the allergic asthma model group, the positive drug group, and high, middle, and low-dose PRPCAP groups could significantly reduce the serum IL-4 content (P<0.01), while high and middle-dose PRPCAP groups could significantly reduce the content of IL-4 in BALF (P<0.05, P<0.01), the middle-dose PRPCAP group could significantly increase the content of IFN-γ in serum (P<0.05), EOS counts in BALF were significantly lower in the positive drug group and all of PRPCAP groups (P<0.01). HE staining showed the pathological changes in the lung tissue of the allergic asthma model group and a mitigating effect in the positive drug group and all of PRPCAP groups. Compared with the normal control group, the expression of MUC5AC mRNA in the lung tissue of rats with allergic asthma was significantly increased (P<0.01). Compared with the model group of allergic asthma rats, the positive drug group and all of PRPCAP groups showed significant decrease in MUC5AC mRNA (P<0.01). Conclusion: The "macromolecule" component of polysaccharides in the Pinelliae Rhizoma Praeparatum Cum Alumine may be the material basis for the efficacy of eliminating dampness and eliminating phlegm.

Objective: To compare the safety and effectiveness of shovel-shaped electrode transurethral plasmakinetic enucleation of the prostate (PKEP) with those of plasmakinetic resection of the prostate (PKRP) in the treatment of benign prostatic hyperplasia (BPH). METHODS: We retrospectively analyzed the clinical data about 78 BPH patients received in Shanghai Ninth People's Hospital from June 2016 to January 2017, 39 treated by shovel-shaped electrode PKEP and the other 39 by PKRP. We observed the patients for 6 months postoperatively and compared the effects and safety of the two surgical strategies. RESULTS: No statistically significant difference was observed between the PKEP and PKRP groups in the operation time (［69.3 ± 8.8］ vs ［72.2 ± 7.9］ min, P = 0.126), but the former, as compared with the latter, showed a markedly less postoperative loss of hemoglobin (［3.9 ± 2.8］ vs ［13.9 ± 5.2］ g/L, P <0.001) and shorter bladder irrigation time (［12.5 ± 1.2］ vs ［43.4 ± 2.8］ h, P <0.001), catheterization time (［64.0 ± 4.5］ vs ［84.8 ± 3.0］ h, P <0.001) and hospital stay (［3.1 ± 0.3］ vs ［5.5 ± 0.4］ d, P <0.001). There were no statistically significant differences between the PKEP and PKRP groups in the postoperative maximum urinary flow rate (Qmax) (［21.62 ± 1.07］ vs ［21.03 ± 0.96］ ml/s, P = 0.12), International Prostate Symptoms Score (IPSS) (5.85 ± 0.90 vs 6.03 ± 0.81, P = 0.279), quality of life score (QoL) (2.0 ± 0.73 vs 2.28 ± 0.72, P = 0.09), postvoid residual urine volume (PVR) (［19.59 ± 6.01］ vs ［20.21 ± 5.16］ ml, P = 0.629), or the incidence rates of urinary incontinence (2.56% ［1/39］ vs 7.69% ［3/39］, P >0.05) and other postoperative complications. CONCLUSIONS Both PKEP and PKRP are effective methods for the treatment of BPH, but PKEP is worthier of clinical recommendation for a better safety profile, more thorough removal of the prostate tissue, less blood loss, shorter hospital stay, and better improved quality of life of the patient.

Objective: To evaluate the predictive value of the proportion of hibernating myocardium (HM) in total perfusion defect (TPD) on reverse left ventricle remodeling (RR) after coronary artery bypass graft (CABG) in patients with heart failure with reduced ejection fraction (HFrEF) by ^99mTc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with ¹⁸F-flurodeoxyglucose (FDG) gated myocardial imaging positron emission computed tomography (PET). Methods: Inpatients diagnosed with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2016 to January 2022 were prospectively recruited. MPI combined with ¹⁸F-FDG gated PET was performed before surgery for viability assessment and the patients received follow-up MPI and ¹⁸F-FDG gated PET at different stages (3-12 months) after surgery. Δ indicated changes (post-pre). Left ventricular end-systolic volume (ESV) reduced at least 10% was defined as RR, patients were divided into reverse remodeling (RR+) group and the non-reverse group (RR-). Binary logistic regression analysis was used to identify predictors of RR. Receiver operating characteristic (ROC) curve analysis was performed and the area under the curve (AUC) was calculated to assess the cut-off value for predicting RR. Additionally, we retrospectively enrolled inpatients with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2021 to January 2022 as the validation group, who underwent MPI and ¹⁸F-FDG gated PET before surgery. Echocardiography was performed before CABG and after CABG (3-12 months). In the validation group, the reliability of obtaining the cut-off value for the ROC curve was verified. Results: A total of 28 patients with HFrEF (26 males; age (56.9±8.7) years) were included in the prospective cohort. HM/TPD was significantly higher in the RR+ group than in the RR- group ((51.8%±17.9%) vs. (35.7%±13.9%), P=0.016). Binary logistic regression analysis revealed that HM/TPD was an independent predictor of RR (Odds ratio=1.073, 95% Confidence interval: 1.005-1.145, P=0.035). ROC curve analysis revealed that HM/TPD=38.3% yielded the highest sensitivity, specificity, and accuracy (all 75%) for predicting RR and the AUC was 0.786 (P=0.011). Meanwhile, a total of 100 patients with HFrEF (90 males; age (59.7±9.6) years) were included in the validation group. In the validation group, HM/TPD=38.3% predicted RR in HFrEF patients after CABG with the highest sensitivity, specificity and accuracy (82%, 60% and 73% respectively). Compared with the HFrEF patients in the HM/TPD<38.3% group (n=36), RR and cardiac function improved more significantly in the HM/TPD≥38.3% group (n=64) (all P<0.05). Conclusions: Preoperative HM/TPD ratio is an independent factor for predicting RR in patients with HFrEF after CABG, and HM/TPD≥38.3% can accurately predict RR and the improvement of cardiac function after CABG.

BACKGROUND: Cerebrospinal fluid (CSF) has been demonstrated as a better source of circulating tumor DNA (ctDNA) than plasma for brain tumors. However, it is unclear whether whole exome sequencing (WES) is qualified for detection of ctDNA in CSF. The aim of this study was to determine if assessment of ctDNA in CSF by WES is a feasible approach to detect genomic alterations of glioblastoma. METHODS: CSFs of ten glioblastoma patients were collected pre-operatively at the Department of Neurosurgery, Sun Yat-sen University Cancer Center. ctDNA in CSF and genome DNA in the resected tumor were extracted and subjected to WES. The identified glioblastoma-associated mutations from ctDNA in CSF and genome DNA in the resected tumor were compared. RESULTS: Due to the ctDNA in CSF was unqualified for exome sequencing for one patient, nine patients were included into the final analysis. More glioblastoma-associated mutations tended to be detected in CSF compared with the corresponding tumor tissue samples (3.56 ± 0.75 vs. 2.22 ± 0.32, P = 0.097), while the statistical significance was limited by the small sample size. The average mutation frequencies were similar in CSF and tumor tissue samples (74.1% ± 6.0% vs. 73.8% ± 6.0%, P = 0.924). The R132H mutation of isocitrate dehydrogenase 1 and the G34V mutation of H3 histone, family 3A (H3F3A) which had been reported in the pathological diagnoses were also detected from ctDNA in CSF by WES. Patients who received temozolomide chemotherapy previously or those whose tumor involved subventricular zone tended to harbor more mutations in their CSF. CONCLUSION Assessment of ctDNA in CSF by WES is a feasible approach to detect genomic alterations of glioblastoma, which may provide useful information for the decision of treatment strategy.
