Abstract
Objective: To analyze the clinical manifestations and gene variations of tumor necrosis factor receptor-associated periodic syndrome (TRAPS). Methods: Clinical data and gene testing of four children and three adult relatives in a family from Puning, Guangdong were retrospectively analyzed. CD4(+)T cells, CD8(+)T cells, B cells, monocytes and NK cells were assessed by flow cytometry. Plasma level of TNFR receptors were assessed by enzyme linked immunosorbent assay (ELISA). TNFRSF1A gene variation was identified by second generation sequencing. Swiss-Model was used to analyze the potential impact of TNFRSF1A gene variation on its protein tertiary structure. Results: For all the patients,periodic fever was the main clinical feature,combined with arthralgia,myalgia,multiple serositis,periorbital edema and migratory cutaneous rash,accompanied with elevated level of acute-phase reactants and increased white blood cell counts during each episode. This disease was found in both gender and every generation in this family. The median age of onset was 2 years, ranging from 6 months to 30 years. The plasma level of TNFR1 of the patients range from 0 to 12.4 ng/L,which was lower than that of the normal controls range from 18.0~22.2 ng/L,while the level of TNFR2 was normal. Also, the numbers of T cells, B cells and monocytes were within normal range; however,number of NK cells in the patients (0.070±0.034) was lower than that in the normal controls (0.152±0.122). The TNFRSF1A variation,located in exon 3: c.295T>A (p.C99S),was found in the proband as well as the other 6 family members,which could induce change of the side chain of amino acid according to the prediction of the three-dimensional structure,subsequently affecting the binding to the receptor. Conclusions: TRAPS is characterized by periodic fever,arthralgia,myalgia,multiple serositis,periorbital edema and migratory cutaneous rash,with a significant decrease in plasma level of TNFR1 and NK cells. The gene sequencing analysis revealed a pathogenic variation in TNFRSF1A gene.

Abstract
BACKGROUND Detection of serum neuron specific enolase (NSE) has high sensitivity and specificity in the diagnosis of lung carcinoma, especially in small cell lung carcinoma, but sometimes serum NSE provided limited help. We report a case of a patient with right lung consolidation combined with elevated serum neuron specific enolase which mimicked lung carcinoma and was ultimately confirmed as pulmonary cryptococcosis by CT-guided percutaneous lung biopsy. METHODS Chest computed tomography (CT) scan and CT-guided percutaneous lung biopsy were performed for diagnosis and blood tests explored the latent etiology. RESULTS The chest CT scan showed right lung consolidation and a pulmonary nodule in lingual segment of upper lobe of left (Figure1A - F). Serum cryptococcal antigen was positive. Pathology of CT-guided percutaneous lung biopsy confirmed pulmonary cryptococcosis (Figure 1G - I). CONCLUSIONS Elevated NSE is not a specific index of lung cancer. Serum cryptococcal antigen and CT-guided percutaneous lung biopsy has high specificity in cryptococcal pneumonia.

Abstract
BACKGROUND Detection of carcinoembryonic Antigen (CEA) in pleural effusion has good clinical application value in differentiating benign and malignant pleural effusion, but sometimes CEA provides limited help. We report a case of a patient with left lung neoplasms combined with bilateral pleural effusion with increased CEA in the pleural effusion whose thoracoscopy pleural biopsy pathology was negative, mimicking lung carcinoma and ultimately confirmed as pulmonary sarcomatoid carcinoma by CT-guided percutaneous lung biopsy. METHODS The chest computed tomography (CT) scan, thoracoscopy pleural biopsy, and CT-guided percutaneous lung biopsy were arranged to explore the etiology of pleural effusion. RESULTS The chest CT scan showed bilateral pleural effusion with left lung neoplasms, pulmonary atelectasis, and left hilar enlargement. Pathology of thoracoscopy biopsy showed pleural inflammation with infiltration of inflammatory cells. Pathology of CT-guided percutaneous lung biopsy confirmed pulmonary sarcomatoid carcinoma. CONCLUSIONS Elevated pleural effusion CEA is not a specific index of lung cancer. CT-guided percutaneous lung biopsy is appropriate for patients presenting with pleural diseases with lung neoplasms, especially when thoracoscopy pleural biopsy result was negative.

Abstract
Objective:The aim of this study was to investigate the association between serum bilirubin levels and the severity of bilateral sudden sensorineural hearing loss (BSSHL). Method:A total of 113 patients with bilateral axillary sputum were enrolled, and the relationship between serum bilirubin levels and initial hearing levels was explored using a univariate and multivariate linear regression model. Result:Compared with the group with moderate and below hearing loss (≤70 dB HL), patients with severe profound HL(>70 dB HL) were more likely to have lower levels of total and indirect bilirubin level, magnesium and relative hearing gain, higher levels of final hearing, white blood counts, neutrophil, platelet and alkaline phosphatase. After adjusting for possible confounders, only serum indirect bilirubin levels were significantly negatively correlated with initial hearing loss in patients with bilateral axillary sputum. 1 μmol/L increase of IBIL was associated with 1.1 dB (95%CI: -2.2, 0.0) reduction in initial hearing loss. Conclusion:Within the normal or mildly elevated range, higher levels of IBIL are independently and significantly associated with less severe hearing loss in BSSHL. It suggested a beneficial effect of bilirubin on auditory system.

Abstract
Objective: To analyze MRI findings of hypovascular clear cell renal cell carcinoma. Methods: The clinical data and MRI findings of patients with hypovascular clear cell RCC confirmed by pathology from February 2016 to March 2017 were retrospectively analyzed in General Hospital of Chinese People's Liberation Army. According to the diameter of the lesions, they were divided into two groups of diameter ≤4 cm and group of diameter > 4 cm. The data was analyzed by using χ(2) to compare clinical data and tumor imaging characteristics between the two groups. Results: Thirty-four patients had 34 hypovascular lesions.The solid part of the tumor showed a slightly hypo- and isointense in 31 lesions, and high signal in 3 lesions; T(1)WI showed slightly lower and equal signal in 29 lesions and high signal in 5 lesions; DWI showed equal low signal in 10 lesions, 24 tumors were mainly high signal; 33 lesions showed pseudo-capsule; tumor hemorrhage in 12 lesions, necrosis in 9 lesions and cystic change in 22 lesions, lipid component in 4 lesions. There were 19 lesions with diameter ≤ 4 cm and 15 lesions with diameter > 4 cm. The surgical methods and bleeding in the lesion were statistically different between the two groups (P<0.05). Conclusion: The MRI findings of hypovascular clear cell RCC are low signal on T(2)WI, high signal on DWI mainly, less lipid. Laparoscopic radical resection was more suitable for lesions with diameter >4 cm and these lesions were more likely to bleed within the tumor.

Abstract
Objective: To investigate the predictive value of multimode MRI features for nuclear grade of clear cell renal cell carcinoma (ccRCC). Methods: From January 2016 to October 2017, 381 patients (387 tumors) with ccRCC proven by pathology in Chinese PLA General Hospital First Medical Center were enrolled (male 293, female 88, age 24-87 years old). The clinical and imaging data of these patients were retrospectively analyzed, including clinical information (gender, age, BMI, smoke, hypertension) and preoperative renal MRI. Pre-and post-contrast MRI features were subjectively scored. The largest diameter of each lesion was measured. Two-sample t-test,Chi-squared test and binuary Logistic regression analysis were used to evaluate the predictive efficacy of clinical and MRI data. Results: According to WHO/ISUP nuclear grade system,all ccRCCs (n=387) were divided into low grade (n=322) and high grade group (n=65). Between two groups, there were significant differences in age and diameter((54±12) vs (59±10) years old, P=0.001; (4.1±2.2) vs (6.2±3.0) cm, P<0.01). In MRI scores,there were significant differences in scores of pseudocapsule, shape and margin,hemorrhage,enhancement degree,cystic-solid,intratumoral vessel,peritumoral vessel, renal sinus invasion, vein thrombosis, lymphadenopathy, necrosis, perinephric invasion and metastasis, DWI signal intensity between high grade group and low grade group (all P<0.01). Binuary Logistic regression analysis showed that shape and margin, enhancement degree and DWI signal intensity were independent predictors for high grade ccRCC (OR=0.181, 95%CI 0.049-0.666; OR=0.393, 95%CI 0.182-0.846; OR=0.336, 95%CI 0.155-0.728). A nomogram model for predicting the risk of high grade ccRCC was constructed. Conclusions: Multimode MRI features can differentiate low grade and high grade ccRCC. The nomogram developed in this study might aid urologist in the pre-operative prediction of nuclear grade of ccRCC,which might contribute to developing treatment strategy.

Abstract
While studies have identified a number of mutations in mantle cell lymphoma (MCL), the list may still be incomplete and contribution to the pathogenesis remains unclear. We analyzed the mutational landscape of four mantle cell lymphoma biopsies obtained during an 8-year period from the same patient with his normal cells serving as control; we also established a cell line from the final stage of the disease. Numerous mutations with high allelic burden have been identified in all four biopsies. While a large subset of mutations was seen only in individual biopsies, the core of 21 mutations persisted throughout the disease. This mutational core is also maintained in the cell line that also displays DNA-methylation and cytokine secretion profiles of the primary mantle cell lymphoma cells. This cell line is uniquely sensitive to clinically relevant inhibitors of Bruton's Tyrosine Kinase. The response to Bruton Tyrosine Kinase's inhibition is enhanced by inhibitors of CDK4/6 and mTOR. Among the mutations seen in the primary and cultured MCL cells, mutations of three genes are involved in the control of H3K4 methylation: demethylase KDM5C, present already in the early disease, and methyltransferase KMT2D and cofactor BCOR, both of which are seen late in the disease and are novel and predicted to be pathogenic. The presence of these mutations was associated with hypermethylation of H3K4. Restoration of KDM5C expression affected expression of numerous genes involved in cell proliferation, adherence/movement, and invasiveness.

Abstract
<p><strong><em>Background</em></strong>: Scoring systems including CURB-65 and Pneumonia Severity Index (PSI) and novel or traditional biomarkers including procalcitonin (PCT) and c-reactive protein (CRP) are very significant for understanding the severity and prognosis in community-acquired pneumonia (CAP) patients, while prognostic items are useful for CAP prognostication and point-of-care decisions. The aim of this study was to investigate the usefulness of peripheral blood routine items in predicting ICU admission and 30-day mortality in CAP patients.</p> <p><strong><em>Methods</em></strong>: A retrospective study was conducted. All adult patients with a primary diagnosis of CAP were included and peripheral blood routine tests were evaluated. Univariate analysis and multivariate logistic regression analysis were used to explore association of risk factors with 30-day mortality among CAP patients. Receiver operating characteristic curves (ROC) were used to evaluate the sensitivity and specificity of peripheral blood routine items and compared with CURB-65 scores in predicting ICU admission and/or 30-day mortality.</p> <p><strong><em>Results</em></strong>: One hundred fifty patients were included and compared with non-ICU admission patients. There was a statistically significant difference in age, co-existing illness, RDW, WBC, and CURB-65 scores ranking in ICU admission patients (p < 0.05). In multivariate logistic regression analysis, we found RDW, WBC, and CURB-65 ≥ 3 scores increased the risk of 30-day mortality by 4.01, 1.65, and 3.43 times, respectively. The area under the curve (AUC) of ROC curves of RDW combined with WBC and CURB-65 was 0.786 (95% CI 0.701 to 0.876) and 0.836 (95% CI 0.764 to 0.908), respectively and the sensitivity was 84.0% and 60.0%, respectively, and the specificity 66.7% and 93.7%, respectively.</p> <p><strong><em>Conclusions</em></strong>: Elevated RDW and WBC increased mortality in adult CAP patients, RDW combined with WBC had a better sensitivity than CURB-65 scores in predicting ICU admission and/or mortality in CAP patients.</p>.

Abstract
Objective: To understand the perceptions, attitudes and treatment selection of Chinese surgeons on the "watch and wait" strategy for rectal cancer patients after achieving a clinical complete response (cCR) following neoadjuvant chemoradiotherapy (nCRT). Methods: A cross-sectional survey was used in this study. Selection of subjects: (1) Domestic public grade III A (provincial and prefecture-level) oncology hospitals or general hospitals possessing the radiotherapy department and the diagnosis and treatment qualifications for colorectal cancer. (2) Surgeons of deputy chief physician or above. Using the "Questionnaire Star" online survey platform to create a questionnaire about cognition, attitude and treatment choice of the "watch and wait" strategy after cCR following nCRT for rectal cancer. The questionnaire contained 32 questions, such as the basic information of doctor, the current status of rectal cancer surgery, the management of pathological complete remission (ypCR) after nCRT for rectal cancer, the selection of examination items for diagnosis of cCR, the selection of suitable people undergoing "watch and wait" approach, the nCRT mode for promotion of cCR, the choice of evaluation time point, the willingness to perform "watch and wait" approach and the treatment choice, and the risk and monitoring of "watch and wait" approach. A total of 116 questionnaires were sent to the respondents via WeChat between January 31 and February 19, 2019. Statistical analysis was performed using Fisher's exact test for categorical variables. Results: Forty-eight hospitals including 116 surgeons meeting criteria were enrolled, of whom 77 surgeons filled the questionnaire with a response rate of 66.4%. "Watch and wait" strategy was carried out in 76.6% (59/77) of surgeons. Seventy surgeons (90.9%) were aware of the ypCR rate of rectal cancer after preoperative nCRT and 49 surgeons (63.6%) knew the 3-year disease-free survival of patients with ypCR in their own hospitals. Fifty-five surgeons (71.4%) believed that patients with ypCR undergoing radical surgery met the treatment criteria and were not over-treated. Three most necessary examinations in diagnosing cCR were colonoscopy (96.1%, 74/77), digital rectal examination (DRE) (90.9%,70/77) and DWI-MRI (83.1%, 64/77). Responders preferred to consider a "watch and wait" strategy for patients with baseline characteristics as mrN0 (77.9%, 60/77), mrT2 (68.8%, 53/77) and well-differentiated adenocarcinoma (68.8%, 53/77). Sixty-six surgeons (85.7%) believed that long-term chemoradiotherapy (LCRT) with combination or without combination of induction and/or consolidation of the CapeOX regimen (capecitabine + oxaliplatin) should be the first choice as a neoadjuvant therapy to achieve cCR. Forty-one surgeons (53.2%) believed that a reasonable interval of judging cCR after nCRT should be ≥ 8 weeks. Forty-four surgeons (57.1%) routinely, or in most cases, informed patient the possibility of cCR and proposed to "watch and wait" strategy in the initial diagnosis of patients with non-metastatic rectal cancer. Thirteen surgeons (16.9%) would take the "watch and wait" strategy as the first choice after the patient having cCR. Fifty-two surgeons (67.5%) would be affected by the surgical method, that was to say, "watch and wait" approach would only be recommended to those patients who would achieve cCR and could not preserve the anus or underwent difficult anus-preservation surgery. Sixteen surgeons (20.8%) demonstrated that "watch and wait" strategy would not be recommended to patients with cCR regardless of whether the surgical procedure involved anal sphincter. Eleven surgeons (14.3%) believed that the main risk of "watch and wait" approach came from distant metastasis rather than local recurrence or regrowth. Twenty-nine of surgeons (37.7%) did not understand the difference between "local recurrence" and "local regrowth" during the period of "watch and wait". Twenty-six surgeons (33.8%) thought that the monitoring interval for the first 3 years of "watch and wait" strategy was 3 months, and the follow-up monitoring interval could be 6 months to 5 years. Surgeons from cancer specialist hospitals had higher approval rate, notification rate, and referral rate of "watch and wait" strategy than those from general hospitals. Thirty-one surgeons (42.5%) considered that the difficulty and concern of carrying out "watch and wait" approach in the future was the disease progress leading to medical disputes. Twenty-six surgeons (35.6%) demonstrated that their concern was lack of uniform evaluation standard for cCR. Conclusions: Chinese surgeons seem to have inadequate knowledge of non-operative management for rectal cancer patients achieving cCR after nCRT and show relatively conservative attitudes toward the strategy. Chinese consensus needs to be formed to guide the non-operative management in selected patients. Chinese Watch & Wait Database (CWWD) is also needed to establish and provide more evidence for the use of alternative procedure after a cCR following nCRT.

Abstract
OBJECTIVES To study the decomposition kinetics of omethoate in blood. METHODS The acetonitrile precipitated protein was added into the blood, with the chromatographic column of a Waters BEH C18 column (2.1 mm×50 mm, 1.7 μm), the mobile phase of 5 mmol/L ammonium acetate aqueous solution-methanol, and the gradient elution with a flow rate of 0.3 mL/min and injection volume of 2 μL. With electrospray ionization (ESI) source and positive ion detection, qualitative and quantitative analyses were taken using multi-reaction monitoring mode. Omethoate standard was added into blank human blood to the mass concentrations of 0.78, 1.40, 2.30, 4.50, and 7.20 μg/mL, and each mass concentration was preserved at 3 temperatures of -20 ℃, 4 ℃, and 20 ℃, respectively. The content of omethoate was detected at different time points (0, 1, 3, 4, 7, 11, 15, 24, 32, 40, 48, 64, 80, 96, and 120 d). RESULTS Different concentrations of omethoate all showed a descended trend in human blood under different temperature conditions. The decomposition in storage environment of -20 ℃, 4 ℃, and 20 ℃ was fit to a one-compartment open model with a first-order kinetic process, which could be expressed as Ct=Coe-αt, with the calculated theoretical values of omethoate concentration close to the measured values. CONCLUSIONS All concentrations of omethoate are decomposed in the blood, which vary a lot in different preservation conditions. It is suggested that blood samples should be frozen and detected timely in suspected omethoate poisoning cases.

Abstract
Objective: To investigate whether MRI findings can differentiate renal epithelioid angiomyolipoma (EAML) from renal no-epithelioid (typical) angiomyolipoma. Methods: A total of 44 patients were collected from General Hospital of PLA.These cases were obtained from January 2009 to June 2015.To retrospectively analyze these mainly MRI findings among 12 cases of EAML (age from 27 to 61 years, male 2 cases, female 10 cases, mean age was 46.7 years); 32 cases of renal no-epithelioid AML (age from 34 to 70 years old, male 9 cases, female 23 cases, mean age was 53.4 years old) as case control study. MRI findings included gender, T(2)WI, the signal on gross fat, pseudocapsle, necrosis or cystic degeneration, DWI, hemorrhage and the peak in three phases of dynamic enhancement.All data were analyzed statistically using SPSS version 19.0 (IBM, Armonk, NY, USA). χ(2) test and a single order chart were used to analyze the enumeration data. Results: Comparing with renal no-epithelioid angiomyolipoma, minimal fat, necrosis or cystic degeneration and hemorrhage were statistical significance. P values were 0.002, 0.007, 0.025, respectively.Gender, solid components of tumors on T(2)WI, the signal of DWI, pesudocapsule and the peak of enhancement had no statistical significance. P values were 0.863, 0.053, 0.479, 0.460, respectively. Conclusion: Comparing with renal no-epithelioid AML, necrosis or cystic degeneration and hemorrhage with minimal fat are characteristic MRI findings of EAML.

Abstract
Current methods to evaluate effects of kinase inhibitors in cancer are suboptimal. Analysis of changes in cancer metabolism in response to the inhibitors creates an opportunity for better understanding of the interplay between cell signaling and metabolism and, from the translational perspective, potential early evaluation of response to the inhibitors as well as treatment optimization. We performed genomic, metabolomic, and fluxomic analyses to evaluate the mechanism of action of the Bruton's tyrosine kinase (BTK) inhibitor ibrutinib (IBR) in mantle cell lymphoma (MCL) cells. Our comprehensive analysis of the data generated by these diverse technologies revealed that IBR profoundly affected key metabolic pathways in IBR-sensitive cells including glycolysis, pentose phosphate pathway, TCA cycle, and glutaminolysis while having much less effects on IBR-poorly responsive cells. Changes in 1H magnetic resonance spectroscopy (MRS)-detectable lactate and alanine concentrations emerged as promising biomarkers of response and resistance to IBR as demonstrated from experiments on various MCL cell lines. The metabolic network analysis on the 13C MRS and 13C LC/MS experimental data provided quantitative estimates of various intracellular fluxes and energy contributions. Glutaminolysis contributed over 50% of mitochondrial ATP production. Administration of the glutaminase inhibitor CB-839 induced growth suppression of the IBR-poorly responsive cells. IMPLICATIONS: Our study demonstrates application of the advanced metabolomic/fluxomic techniques for comprehensive, precise, and prompt evaluations of the effects of kinase inhibition in MCL cells and has strong translational implications by potentially permitting early evaluation of cancer patient response versus resistance to kinase inhibitors and on design of novel therapies for overcoming the resistance.

Abstract
Objective:To investigate the effect of butylphthalide on plasma nitric oxide(NO) and endothelin-1(ET-1) in severe elderly OSAHS patients. Method:A total of 120 severe elderly OSAHS patients were chosen by PSG measurement. According to random number table method, OSAHS patients were randomly divided into non-invasive ventilation control group(n=40), butylphthalide treatment group(n=40) and butylphthalide combined with non-invasive ventilation group (n=40). Non-invasive ventilation control group was given double level airway positive pressure ventilation treatment for six months, butylphthalide treatment group accepted oral butylphthalide therapy for six months, butylphthalide combined with non-invasive ventilation group was given double level airway positive pressure ventilation treatment and accepted oral butylphthalide therapy for six months. The changes of plasma NO and ET-1 were detected by immunoenzyme adsorption before treatment and three and six months after treatment. Result:The difference of plasma NO and ET-1 before treatment in the three groups was not statistically significant (P>0.05). Compared with before treatment, the level of plasma NO decreased and the level of plasma ET-1 increased in the three groups after three and six months treatment (P<0.01). Compared with butylphthalide treatment group, the level of plasma NO increased and the level of plasma ET-1 decreased after 3 and 6 months of treatment in both non-invasive ventilation control group and butylphthalide combined with non-invasive ventilation group (P<0.05). Compared with non-invasive ventilation control group, the level of plasma NO increased and the level of plasma ET-1 decreased after 3 and 6 months of treatment in butylphthalide combined with non-invasive ventilation group (P<0.05). Conclusion:Butylphthalide may improve the vascular endothelial function of severe elderly OSAHS patients by increasing the level of NO and decreasing the level of ET-1 in plasma.

Abstract
Objective:To investigate the diagnostic efficiency of HCY and NO/ET-1 to cognitive dysfunction in patients with severe obstructive sleep apnea hypopnea syndrome, and to interfere with the cognitive function of severe OSAHS patients. Method: Eighty-six patients with OSAHS were divided into mild group (22 cases), moderate group (23 cases), severe group (41 cases) and healthy physical examination group (50 cases). The levels of serum HCY and NO/ET-1 were compared between the four groups. The Montreal cognitive assessment scale was used to evaluate the incidence of mild cognitive impairment in severe OSAHS group, and the correlation between the level of serum HCY, NO/ET-1 and cognitive function in severe OSAHS group was analyzed. Result:The level of serum HCY in patients with severe OSAHS with cognitive impairment was(32.28±3.92)μmol/L, higher than that of the cognitive moderate group(26.34±4.05)μmol/L, and mild group (18.62±3.29)μmol/L. The level of serum NO/ET-1 in patients with severe OSAHS with cognitive impairment was (0.69±0.19), higher than that of the cognitive moderate group(2.76±0.28), and mild group (3.98±0.37), the difference was statistically significant (P<0.05). In severe group, there was a negative correlation between the level of serum HCY and the score of MoCA and its subscores (P<0.05), and there was a positive correlation between the total scores of NO/ET-1 and MoCA and their subscores (P<0.05), and negative correlation between HCY and NO/ET-1 (P<0.05). The area under the ROC curve of predicting serum HCY and NO/ET-1 levels in severe OSAHS patients with cognitive impairment were 0.788(95%CI0.654-0.921) and 0.770 (95%CI0.642-0.899). Conclusion:Serum HCY and NO/ET-1 were the factors influencing the formation of cognitive impairment in severe OSAHS patients. The level of HCY was negatively correlated with the degree of cognitive impairment, and NO/ET-1 was positively correlated with the degree of cognitive impairment.

Abstract
Japanese encephalitis (JE) is the important viral encephalitis in China. In the 1940s, JE was confirmed to be epidemic in China. In 1971, the annual incidence rate was 20.92/100 000. Since 2008, JE vaccine was included in the national Expanded Program of Immunization (EPI). In 2013, the incidence of Japanese encephalitis decreased to 0.16/100 000. JE virus is divided into five genotypes, and genotype 1, 3 and 5 JE virus was isolated in China. Genotype 1 JE virus was the mainly genotype currently circulated in China. In recent years, the characteristics of the population of JE have been changed to adult, especially in the northern provinces of China. JE prevention and control faces new challenges.

Abstract
Objective: To study perioperative period conditions of total and partial colpocleisis with severe pelvic organ prolapse (POP) in elderly patients. Methods: From Jan. 2014 to Oct. 2017 286 severe POP elderly patients underwent total or partial colpocleisis. The mean age was (76.0±5.1) years (60-90 years) . Of which, 220 patients (76.9%, 220/286) presented more than one kind of medical disease. The operative time, intraoperative blood loss, hospital stay after surgery, postoperative complications, preoperative urinary dysuria symptoms of total and partial colpocleisis in treatment of 286 patients were analyzed. Results: In 286 patients, 172 patients (60.1%) underwent total colpocleisis and 114 patients (39.9%) underwent partial colpocleisis. Totally 48 patients (16.8%) in 286 patients underwent anti-urinary incontinence procedure. The mean operating time of 286 patients was (67±22) minutes,the mean blood loss was (52± 57) ml, the mean hospital stay after surgery was (5.9±1.9) days (2-16 days) . The rate of postoperative complications was 8.7% (25/286) . Those complications including 1 case of bladder injury during operation, 3 cases of postoperative pelvic hematoma, 1 case of intestinal obstruction, 5 cases of atrial fibrillation, 10 cases of postoperative morbidity, 3 cases of pulmonary embolism, 1 case of lower limb thrombosis, 1 case of urinary retention underwent electrical stimulation treatment because of ineffective application of urinary retention catheter. The mean operating time was (67±22) minutes in total colpocleisis and (68±20) minutes in partial colpocleisis (P>0.05) , the mean blood loss was (58±62) ml in total colpocleisis and (41±45) ml in partial colpocleisis (P>0.05) , the mean hospital stay after surgery was (5.9±1.9) days in total colpocleisis and (6.0±1.8) days in partial colpocleisis (P>0.05) , the rate of post operative complications was 8.1%(14/172) in total colpocleisis and 9.6% (11/114) in partial colpocleisis (P>0.05) , respectively; those four of comparisons showed no significant difference. There were 129 patients (45.1%, 129/286) with voiding difficulty before surgery; the mean postvoid residual volumes of the above two operation types of people after operation were (35±43) and (34±41) ml, which showed no significant difference (P>0.05) . Conclusions: Colpocleisis is a safe and effective management in selected elderly patients with severe POP, who no longer desire to maintain vaginal coital function. There is no significant difference in the perioperative period conditions between total and partial colpocleisis. The choice of surgical procedure is based on factors such as the presence or absence of malignancy in the uterus, age and willingness of the patient, and general condition.

Abstract
We report the experimental generation of highly energetic carbon ions up to 48 MeV per nucleon by shooting double-layer targets composed of well-controlled slightly underdense plasma and ultrathin foils with ultraintense femtosecond laser pulses. Particle-in-cell simulations reveal that carbon ions are ejected from the ultrathin foils due to radiation pressure and then accelerated in an enhanced sheath field established by the superponderomotive electron flow. Such a cascaded acceleration is especially suited for heavy ion acceleration with femtosecond laser pulses. The breakthrough of heavy ion energy up to many tens of MeV/u at a high repetition rate would be able to trigger significant advances in nuclear physics, high energy density physics, and medical physics.

Abstract
BACKGROUND To report a case of broncholithiasis with recurrent hemoptysis and fever initially misdiagnosed as active tuberculosis. METHODS The chest contrast-enhanced CT scan, electronic bronchoscope, and ultrathin bronchoscope were performed leading to the diagnosis of broncholithiasis, open lung lobectomy was done after thoracic surgery consultation. RESULTS The chest contrast-enhanced CT scan showed a high-density intratracheal shadow and calcified lymph nodes. Ultrathin bronchoscopy manifested calcified lesions located at the distal portion of the right lower lobe bronchus. Histopathology of lobectomy showed lithiasis in the right lower lobe tracheobronchial tree. CONCLUSIONS We should pay attention to calcified intratracheal lesions and make differential diagnosis with tuberculosis, especially when accompanied with calcified lymph nodes and fever.

Abstract
BACKGROUND High serum neuron-specific enolase (NSE) level has been in use as a tumor marker; however, some physicians may ignore NSE levels in serum, especially when the patients are asymptomatic. Here we report a case that a 51 year old female patient with no respiratory symptoms who had a NSE level which increased extremely over three months and was eventually diagnosed small cell lung cancer (SCLC). METHODS Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in right pulmonary hilar enlarged lymph node was performed for diagnosis. RESULTS EBUS showed right pulmonary hilar lymph node enlargement. A TBNA biopsy histopathology diagnosed SCLC. CONCLUSIONS We should pay attention to high serum NSE levels, especially when the index increased extremely over a short time.

Abstract
Objective: To evaluate the clinical value and outcomes of technical improvement of hybrid operatical clipping for large paraclinoid internal carotid artery aneurysms. Methods: A review was conducted on 18 cases of large paraclinoid internal carotid artery aneurysm which were clipped by balloon non-fluoroscopic occlusion of the parent artery via a micro-bone window frontolateral approach in hybrid operating room at Neurosurgery Department of Tianjin Medical University General Hospital from June 2014 to December 2017. There were 8 males and 10 females with age of (63±4) years. There were 6 cases of unruptured aneurysm and 12 cases of ruptured aneurysm of subarachnoid hemorrhage (6 cases of grade Ⅱ, 4 cases of grade Ⅲ and 2 cases of grade Ⅳ in Hunt-Hess classification). Frontolateral approach incision (average length of about 5 cm) and bone window about 3 cm×3 cm were performed. No incision of the neck was needed to expose the internal carotid artery for temporary occlusion. In the operation, the balloon was slowly pushed to the preset position of the internal carotid artery under non-fluoroscopy. The balloon was expanded to block the blood flow of internal carotid artery. Then aneurysm was clipped. The balloon was loosened and retraced to the guiding catheter after clipping. The clipping condition was examined by cerebral angiography. If there was residual aneurysm neck or stenosis of the parent artery, the balloon was pushed under non-fluoroscopy again to temporary occlusion and the clip was adjusted until the aneurysm neck was clamped satisfactorily. Results: Eighteen aneurysms were successfully clipped in hybrid operating room. Fourteen aneurysms showed complete occlusion of the aneurysm neck and no stenosis of the parent artery. Four cases showed residual aneurysm neck after clipping by intraoperative angiography, then aneurysms were clipped satisfy by adjusting the aneurysm clip. The patients were followed up for 3 months to 1 year. Ten patients recovered well (modifed Rankin score (mRS): 0), and 3 patients had no obvious disability (mRS: 1). Two patients with Hunt-Hess grade Ⅲ were slightly disabled (mRS: 2). 1 patients with Hunt-Hess grade Ⅲ were moderately disabled (mRS: 3). 1 patients with Hunt-Hess grade Ⅳ were severely disabled (mRS: 4). One elderly patients with Hunt-Hess grade Ⅳ were seriously disabled (mRS: 5). Conclusions: Application of balloon non-fluoroscopic occlusion clipping for large paraclinoid internal carotid artery aneurysm via a micro-bone window frontolateral approach is safe, effective and minimally invasive.
