Objective To evaluate the relationship between the incidence rate of hepatic encephalopathy in patients with cirrhosis and the model for end-stage liver disease (MELD).Methods The total of 120 patients with decompensated cirrhosis were enrolled and followed-up.MELD score was obtained to observe the incidence of hepatic encephalopathy.Results The incidence of hepatic encephalopathy was 44.17％(53/120).MELD score in hepatic encephalopathy patients was significantly higher than that in none hepatic encephalopathy patients[(21.69 ± 9.22) scores vs.(9.32 ± 4.63) scores],and there was significant difference (P ＜ 0.05).With the increase of MELD score,the incidence of hepatic encephalopathy increased (P ＜ 0.01).The best critical value of MELD score was 14.13 scores (the sensitivity of 86.05％ and the specificity of 88.37％),when MELD ≥14.13 scores,the incidence of hepatic encephalopathy within 3 months was significantly higher [63.16％(48/76) vs.11.36％(5/44)] (x2 =30.32,P＜ 0.01).Conclusion MELD can help predicting the incidence of hepatic encephalopathy in decompensated cirrhosis patients.

Fifteen patients with chronic renal failure(CRF)underwent laparoscopic cholecystectomy(LC)at carbon dioxide(CO2)pneumoperitoneum pressure of 10-12 mm Hg(Group A,n=9)or 13-15 mm Hg(Group B,n=6).Renal function and urinary volume(UV)of Group A showed no remarkable change following the operation.But in Group B,the levels of blood urine nitrogen(BUN)and serum creatine(Scr)were increased significantly,and creatinine clearance rate(Ccr)and UV were remarkably decreased(P＜0.05).These variants gradually retumed tO the preoperative levels after 1 week.The analysis showed that laparoscopic choleeystectomy at CO2 pneumoperitoneum pressure of 10-12 mm Hg in CRF patients might be safe.Higher CO2 pneumoperitoneum pressure could result in reversible renal Email:yuanhuizhong2000@yahoo.com.cnfunction change.

Objective To assess the influence between managements in emergency room(ER) andoutcome of severe traumatic brain injury (TBI),in order to provide inference for treatment.Methods A retrospective analysis was performed in severe TBI patients and recorded next indexes.(1) The managements in ER,including endotracheal intubation and oxygenation,fluid resuscitation,and mannitol intake.(2) The vital signs arriving at ICU,including systolic pressure and blood oxygen saturation.(3) Prognostic indicators including inhospital mortality and days during ICU,the scores of Glasgow outcome scale (GOS) at discharge and 6 months after injury.Results In 140 severe TBI patients,65 patients (46.4％) died during ICU.The mortality of patients with endotracheal intubation [65.0％ (39/60)] was significantly higher than that without endotracheal intubation [32.5％(26/80)](P＜ 0.01).The mortality in whether fluid resuscitation and using mannitol had no significant difference [44.7％ (46/103) vs.51.4％ (19/37),49.2％ (31/63) vs.44.2％ (34/77)] (P ＞0.05).In days during ICU,there was no significant difference among the three treatment measures (P＞ 0.05).In GOS grade at discharge and 6 months after injury,the proportion of 4 and 5 grade were 8.3％ (5/60) and 25.0％ (15/60) in patients with endotracheal intubation,while 27.5％ (22/80) and 52.5％ (42/80) in patients without endotraeheal intubation (P ＜ 0.01).In fluid resuscitation and using mannitol patients,there were no significant difference(P ＞ 0.05).Conclusion Treating severe TBI patients in ER,endotracheal intubation should be carefully chosen,fluid resuscitation and mannitol may not be given.

Objective To observe the incidence of severe acute pancreatitis (SAP) in obese acute pancreatitis (AP) patients with medical treatment, and evaluate the impact of obesity in AP progression.Methods A multicenter prospective controlled study was conducted. APACHE Ⅱ scoring system was used to evaluate the severity of AP. Results 161 patients with mild AP(MAP) were enrolled, according to the cut-off point of 25 kg/m2, these patient were divided into obese group (79 patients) and non-obese group (82patients). The levels of CRP, hypertriacylglycerolemia, complication rate, incidence of SAP and mortality were observed under the circumstance of identical medical treatment. The levels of CRP in obese group and non-obese group were (117±109 ) mg/L and (35±36 ) mg/L(P<0.01). The number of obese patients with hypertriacylglycerolemia was two times as many as that in non-obese patients, but there was no significantly difference. There was no local complication in both groups, but the incidence of systematic complication in obese patients (20.3%) was significantly higher than that in non-obese group (6.1%, P<0.01). 16patients (20.3%) in obese group progressed into SAP, which was significantly higher than that in non-obese group (5 patients, 6.1%, P<0.01). One patient(1.3%) died in obese group, but no one died in non-obese group. In MAP patients with APACHE Ⅱ 4～7 points, the incidence of SAP (43.3%) in obese group was significantly higher than that in non-obese group (18.5%, P<0.05). Conclusions Obese MAP patients with APACHE Ⅱ 4～7 points were prone to develop into SAP. More aggressive interventions are needed.

Objective:To estimate in-hospital mortality after knee replacement (KR) and to assess its trend and risk factors in China.Methods:We included patients undergoing KR in the Hospital Quality Monitoring System in China (2013-2019) to estimate in-hospital mortality after KR and assessed relation of patient's and hospital's characteristics (year of surgery, age, gender, marital status, primary indication, Charlson comorbidity index, geographic location, hospital type, hospital volume of KR, and surgery type) to in-hospital mortality using multivariable Poisson regression.Results:The annual amount of KR has increased from 20 307 in 2013 to 35 757 in 2019, and has maintained an upward trend for 7 years. The mean age of patients having KR increased from 64.9 years in 2013 to 66.6 years in 2019. Of the total 218 923 KRs, 63 deaths (0.29‰) occurred within 30 days before discharging. Older age was associated with higher in-hospital mortality ( P for trend <0.001). Male gender had higher incidence of in-hospital mortality compared with female [relative risk (RR), 2.5; 95% CI: 1.5, 4.1]. Single marital status was associated with higher, albeit non-statistically significant, in-hospital mortality than married patients (RR, 2.1; 95% CI: 0.9, 4.6). Higher Charlson comorbidity index was associated with increased risk of in-hospital mortality ( P for trend <0.001). Risk of in-hospital mortality decreased with more hospital-year knee replacement surgeries ( P for trend <0.001). In-hospital mortality varied by geographic regions, with the lowest mortality in East region (0.16‰), followed by South-West (0.31‰), South-Central (0.31‰), North region (0.33‰), North-West (0.54‰) and North-East (0.59‰). Conclusion:In-hospital mortality after KR in China was relatively low. Older age, male gender, higher Charlson comorbidity index and lower hospital-year knee replacement surgeries were risk factors for in-hospital mortality. The mortality varied greatly according to the geographic location of hospital.

BACKGROUND: There are limited data on the resource utilization of total knee arthroplasty (TKA) in China. This study aimed to examine the length of stay (LOS) and inpatient charges of TKA in China, and to investigate their determinants. METHODS: We included patients undergoing primary TKA in the Hospital Quality Monitoring System in China between 2013 and 2019. LOS and inpatient charges were obtained, and their associated factors were further assessed using multivariable linear regression. RESULTS: A total of 184,363 TKAs were included. The LOS decreased from 10.8 days in 2013 to 9.3 days in 2019. The admission-to-surgery interval decreased from 4.6 to 4.2 days. The mean inpatient charges were 61,208.3 Chinese Yuan. Inpatient charges reached a peak in 2016, after which a gradual decrease was observed. Implant and material charges accounted for a dominating percentage, but they exhibited a downward trend, whereas labor-related charges gradually increased. Single marital status, non-osteoarthritis indication, and comorbidity were associated with longer LOS and higher inpatient charges. Female sex and younger age were associated with higher inpatient charges. There were apparent varieties of LOS and inpatient charges among provincial or non-provincial hospitals, hospitals with various TKA volume, or in different geographic regions. CONCLUSIONS The LOS following TKA in China appeared to be long, but it was shortened during the time period of 2013 to 2019. The inpatient charges dominated by implant and material charges exhibited a downward trend. However, there were apparent sociodemographic and hospital-related discrepancies of resource utilization. The observed statistics can lead to more efficient resource utilization of TKA in China.

BACKGROUND: The detection of driver oncogenes of lung cancer is of great importance. There are various gene detection techniques nowadays which are different from each other. We carried out this study to investigate the specificity and sensitivity of assay panels based on an Amplification Refractory Mutation System-polymerase chain reaction (ARMS-PCR) technique of Amplification Mutation Specific System (AMSS) in detection of lung cancer gene mutation. To estimate the applicable value of assay panels in clinical settings. METHODS: We collected cancer tissue specimens or fluid specimens from 309 patients. Mutation results were presented for those samples previously detected by ARMS-PCR. In comparison, we carried out AMSS-PCR using (epidermal growth factor receptor, EGFR) assay panel and Six-Alliance assay panel as well as Sanger sequencing. Software SPSS 22.0 (SPSS IBM) was used for statistical analysis. RESULTS: The rates of consistency between the results by assay panels and Sanger sequencing or ARMS-PCR were 97.41% and 97.73%, respectively. Besides, EGFR assay panel had higher consistency rates with other detection methods than Six-Alliance assay panel. As for consistency test, the Kappa values of assay panels with Sanger sequencing, assay panels with ARMS-PCR, and ARMS-PCR with Sanger sequencing were 0.946, 0.953, and 0.913, respectively. The receiver operating characteristic curve (ROC) area under curve (AUC) of assay panels was 0.976 referring to Sanger sequencing, and 0.975 as ARMS-PCR was referred to. CONCLUSIONS AMSS-PCR can make an optimal cancer gene mutation detection method for clinical settings.
