Objective: To analyze the trends, gender, and age differences in the incidence of lip and oral cavity cancer in Chinese population from 1990 to 2021 and predict future incidence trends, providing a scientific basis for disease prevention and public health policy. Methods: Incidence data of lip and oral cavity cancer in Chinese population from the Global Burden of Disease (GBD) database from 1990 to 2021 were analyzed. The Joinpoint regression model was used to assess temporal trends, the age-period-cohort model was used to evaluate the independent effects of age, period, and cohort, and the Bayesian age-period-cohort model (BAPC) model was used to predict incidence trends from 2022 to 2044. Results: From 1990 to 2021, the age-standardized incidence rate of lip and oral cavity cancer in Chinese population increased from 2.39/100 000 to 3.76/100 000, and the crude incidence rate rose from 1.71/100 000 to 4.85/100 000. The incidence rate in males was higher and increased more rapidly than in females. Higher incidence rates were prevalent among older populations, a rapid increase in incidence rates occurred during 2003 to 2012, and earlier birth cohorts showed overall higher risks. BAPC predictions indicated a continued rise in incidence from 2022 to 2044. During this period, male incidence stabilized while female incidence increased at a relatively faster rate. Conclusion The incidence of lip and oral cavity cancer in Chinese population has revealed a continuous upward trend, particularly among males and older populations. Future prevention strategies should focus on these high-risk populations.

ObjectiveTo analyze the epidemiological trends and characteristics of brucellosis in humans (hereinafter referred to as brucellosis) in Tangshan City, Hebei Province from 2016 to 2023, and to provide a scientific basis for formulating brucellosis prevention and control strategies in the region. MethodsThe incidence data of human brucellosis in Tangshan City from 2016 to 2023 were collected from the China Disease Prevention and Control Information System. The diagnosis time, infection route, and clinical characteristics of the cases were obtained from the case investigation reports. Descriptive epidemiological methods were used to analyze the temporal, spatial, demographic distributions, and clinical characteristics of human brucellosis. Brucella species were identified using agglutination tests with bacterial suspension and A/M antigen-positive serum. ResultsA total of 2 193 cases of human brucellosis were confirmed and clinically diagnosed in Tangshan City from 2016 to 2023, with the peak incidence occured from March to August, and which exhibited distinct geographic distribution patterns. The highest incidence rate was found in people aged 60‒<70 years. The occupation of cases were primarily farmers. The incidence rate in males (528/100 000) was higher than that in females (184/100 000). All cases had confirmed exposure to infected animals or contaminated animal products. ConclusionThe epidemic of human brucellosis in Tangshan exhibited an overall steady downward trend from 2016 to 2023, except for a slight increase in 2016 and 2021, with the incidence rate controlled at 289/100 000‒335/100 000. The prevention and control situation of human brucellosis still remains severe, with the highest incidence rate in the eastern region of Tangshan, which are characterized by the breeding, slaughtering, and processing of cattle and sheep. Therefore, it it is necessary to enhance the prevention and control of human brucellosis among the personnel engaged in these industries in the eastern areas.

Objective To investigate the risk factors associated with post traumatic cerebral infarction (PTCI) after craniotomy hematoma evacuation for severe traumatic brain injury (sTBI) so as to provide clinical reference for the early prevention of postoperative PTCI.Methods A retrospective case control study was conducted to analyze the clinical data of 558 sTBI patients who received craniotomy hematoma evacuation admitted to Changsha Hospital of Traditional Chinese Medicine from October 2006 to June 2016.There were 340 males and 218 females,aged 15-71 years,with an average of 47.8 years.Among them,75 patients were at the age of less than 30 years,315 were at 30-50 years,and 168 were above 50 years.According to the Glasgow coma score (GCS),there were 127 patients with 3-4 points,124 with 5-6 points,and 307 with 7-8 points.The patients were divided into PTCI group (51 patients)and non-PTCI group (507 patients).The related indicators of the two groups of patients after admission were collected,including gender,age,injury cause,GCS,skull base fracture,traumatic subarachnoid hemorrhage (tSAH),cerebral hernia,hypotension,the time from injury to craniotomy,and whether decompressive craniectomy was performed.Univariate analysis was first performed for these factors,followed by multivariate logistic regression analysis.Results There were no significant differences in gender,age,injury cause,skull base fracture,and decompressive craniectomy between PTCI group and control group (P ＞ 0.05).In the PTCI group,there were 29 patients with GCS of 3-4 points,17 with 5-6 points,and five with 7-8 points;there were 48 patients with tSAH,37 patients with cerebral hernia,and 18 patients with hypotension.In terms of the time from injury to craniotomy,it took ＜ 3 hours in 30 patients,3-6 hours in 12,6-12 hours in five,and ＞ 12 hours in four.In the non-PTCI group,there were 98 patients with GCS of 3-4 points,107 with 5-6 points,and 302 with 7-8 points.There were 34 patients with tSAH,117 with cerebral hernia,and 35 with hypotension.In terms of the time from injury to craniotomy,it took ＜3 hours in 294 patients,3-6 hours in 130,6-12 hours in 68,and ＞ 12 hours in 15.The differences between the two groups were statistically significant (P ＜ 0.05).Multivariate logistic regression analysis indicated that GCS of 3-6 points,tSAH,cerebral hernia,time from injury to craniotomy,and hypotension were significantly associated with PTCI after operation for sTBI (P ＜ 0.01).Conclusions GCS of 3-6 points,tSAH,cerebral hernia,duration from injury to craniotomy,and hypotension time ＞ 3 hours are the high risk factors of PTCI in sTBI patients after craniotomy.For patients with these high risk factors,craniotomy should be performed in time,and the perioperative blood pressure and intracranial pressure stability should be maintained so as to relieve vasospasm.

Objective To summarize the clinicopathological characteristic,diagnosis and treatment of iatrogenic biliary tree destruction.Methods The retrospective cross-sectional study was conducted.The clinical data of 11 patients with iatrogenic biliary tree destruction who were admitted to the Chinese PLA General Hospital (9 patients) between January 1990 and December 2013 and Beijing Tsinghua Changgung Hospital (2 patients) between December 2014 and May 2017 were collected.Observation indicators:(1) causes and parts of destruction;(2) clinical manifestation;(3) imaging performance;(4) treatment;(5) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect long-term prognosis of patients up to April 2018.Measurement data with skewed distribution were described as M (range).Results (1) Causes and parts of iatrogenic biliary tree destruction:causes of iatrogenic biliary tree destruction in 11 patients:transcatheter arterial embolization for hepatic hemangioma was performed in 7 patients,high intensity focused ultrasound for hepatic hemangioma in 1 patient,arterial embolization for false aneurysm in 1 patient,sclerosant injection for hepatic echinococcosis in 1 patient,and cyberknife radiotherapy for hepatocellular carcinoma in 1 patient.Parts of biliary tree destruction of 11 patients:5,3,2 and 1 respectively involved bilateral biliary tree,right biliary tree,bilateral main biliary ducts in hepatic port and left biliary tree.(2) Clinical manifestation:11 patients had symptoms of recurrent chills and fever,and combined with different degrees of jaundice.The initial symptom occurred in 2 weeks to 3 months after iatrogenic biliary tree destruction.Of 11 patients,7 were complicated by different degrees of hepatic abscess,and abscess involving left and right half liver were detected in 4 patients,aggregating in right half liver in 2 patients and aggregating in left half liver in 1 patient.Eight patients had secondary biliary cirrhosis,portal hypertension,splenomegaly and hypersplenism during the late course of disease.(3) Imaging performance:magnetic resonanced cholangio-pancreatography (MRCP) and cholangiography examinations showed missing bile duct in necrosis area,beading-like stricture and dilation of damaged biliary tree,reducing proximal bile duct branches and associated gallbladder necrosis.CT and MRI examinations showed that structure of distribution area of damaged biliary tree disappeared or bile duct wall was thickened,and hepatic abscesses of patients were scattered and multiple.Five patients had significantly secondary liver atrophy-hypertrophic syndrome,showing atrophy of right liver and hyperplasia of left liver.Radiotherapy-induced biliary tree destruction showed a characteristic of continued progress,localized abnormality in the early stage and typical imaging changes after the damage stability in the late stage.(4) Treatment:of 11 patients,4 didn't undergo surgery,and 7 underwent 18 intentional and conclusive surgeries (1-4 times / per case).(5) Follow-up:11 patients were followed up for 2-132 months,with a median time of 73 months.During the follow-up,2,1 and 8 patients had respectively excellent,good and poor prognoses.Among 11 patients,4 died (2 died of severe infection and 2 died of biliary cirrhosis),and 7 survived.Conclusions Iatrogenic biliary tree destruction is easy to cause hepatic abscess,liver atrophy-hypertrophic syndrome or biliary cirrhosis,and it can be diagnosed by imaging examination.The definitive treatment should be followed by liver resection or liver transplantation of involving area according to the extent of damage.

Due to the theoretical and technique limitation of traditional surgery,surgical treatment of complex intrahepatic biliary diseases was left for an unresolved difficult problem of the last century.Uncertainties of the anatomical,physiological,pathological changes and surgical techniques in the intrahepatic biliary tract contribute to this complexity.Through integrated application of modern scientific technology and traditional medicine methods and systematic optimization and innovation of biliary surgical theories and techniques,authors have developed a paradigm of precision biliary surgery which is characterized by high quantification,visualization and controllability.The establishment of the precise biliary surgical system solves the difficulty in surgeries for intrahepatic biliary diseases,puts forward the biliary surgery from extrahepatic ducts,hilar ducts to intrahepatic ducts,entering a new segment era of the biliary surgery marked by precision treatment of intrahepatic biliary diseases.

Objective To explore the relationship between diameter of liver hemangioma and operation risk.Methods The clinical data of 362 patients with liver hemangioma who were admitted to the PLA General Hospital from January 2006 to January 2014 were retrospectively analyzed.All patients were divided into the 3 groups according to diameter of gross specimen,217 with tumor diameter≥5 cm and ≤ 10 cm in the large hemangioma group,119 with tumor diameter ＞ 10 cm and ≤20 cm in the giant hemangioma group and 26 with tumor diameter≥20 cm in the extremely large hemangioma group.The operation method included open surgery and laparoscopic surgery.Hepatectomy and enucleation of liver hemangioma were major operation procedures.The operation time,volume of intraoperative blood loss,number of patients with intraoperative blood transfusion,number of patients with postoperative complications and duration of hospital stay were evaluated.Count data were analyzed using the chi-square test.Measurement data with normal distribution were presented as (x) ± s,and comparison among groups was analyzed using the ANOVA.Skewed distribution data were described as M (P25,P75),comparison among groups was analyzed by Kruskal-wallis test and pairwise comparison was done by the MannWhitney U test.Results All patients underwent operation successfully without perioperative death,including 315 receiving open surgery (175 in the large hemangioma group,114 in the giant hemangioma group and 26 in the extremely large hemangioma group) and 47 receiving laparoscopic surgery (42 in the large hemangioma group and 5 in the giant hemangioma group).The operation time,volume of intraoperative blood loss,number of patients with blood transfusion,number of patients with postoperative complications and duration of hospital stay were 160 minutes (125 minutes,205 minutes),300 mL (100 mL,500 mL),31,5 and 8 days (7 days,9 days) in the large hemangioma group,220 minutes (175 minutes,275 minutes),500 mL (300 mL,1 000mL),36,5 and 9 days (8 days,10 days) in the giant hemangioma group,330 minutes (280 minutes,420 minutes),1 975 mL (800 mL,4 000mL),20,7 and 11 days (9 days,13 days) in the extremely large hemangioma group,respectively,with significant differences (x2 =84.24,80.94,53.65,31.54,47.67,P ＜ 0.05).The operation time,volume of intraoperative blood loss,number of patients with intraoperative blood transfusion and duration of hospital stay were compared,showing significant differences between large hemangioma group and giant hemangioma group (Z =6.39,6.51,x2 =11.29,Z =4.73,P ＜ 0.05),with significant differences between large hemangioma group and extremely large hemangioma group and between giant hemangioma group and extremely large hemangioma group (Z =7.28,6.91,x2=51.22,Z =5.57,P ＜ 0.05;Z =5.33,4.86,x2=17.69,Z =3.5 1,P ＜ 0.05).Seventeen patients had postoperative complications with an incidence of 4.70％ (17/362),intra-abdominal hemorrhage were detected in 7 patients,perihepatic effusion in 4 patients,pleural effusion in 3 patients,bile leakage in 2 patients and fat liquefaction of abdominal incision in 1 patient.There was no significant difference in the number of patients with postoperative complications between large hemangioma group and giant hemangioma group (x2 =0.41,P ＞ 0.05).There were significant differences in the number of patients with postoperative complications between large hemangioma group and extremely large hemangioma group and between giant hemangioma group and extremely large hemangioma group (x2 =24.96,11.67,P ＜ 0.05).Conclusions Diameber of liver hemangioma is associated with operation time,volume of intraoperative blood loss,number of patients with intraoperative blood transfusion,number of patients with postoperative complications and duration of hospital stay,and there is a high risk in the surgical treatment of patients with liver hemangioma diameter≥20 cm.

Objective To compare the outcomes of giant hepatic hemangioma undergoing enucleation and hepatectomy and to summarize our experience of surgical management of liver hemangioma.Methods A retrospective study was conducted in patients undergoing giant hepatic hemangioma resection (lager than 10 cm in size) in General Hospital of PLA,during 2006 through 2014.Patients were divided into two groups according to the types of operation.Results Of 145 patients with giant liver hemangioma,81 underwent enucleation and 64 had hepatectomy.The differences of tumor size (12.0 cm vs.15.5 cm,u =3.68,P ＜0.01),time of operation (210 min vs.280 min,u =3.89,P ＜ 0.01) and the ratio of inflow control (81.5％ vs.56.3％,x2 =10.91,P ＜ 0.01) of enucleation and hepatectomy was significant.The difference of intraoperative blood loss (500 ml vs.800 ml,u =1.85,P =0.07) and the postoperative morbidity (8.6％ vs.7.8％,x2=0.03,P =0.86) was not statistically significant.There was no inhospital mortality in both groups.Conclusions Both of enucleation and hepatectomy are effective operative approaches for giant liver hemangioma,patients with liver hemangioma should be prudently chosen for surgery,and the operation type should be individualized with the guidance of precision liver surgery.

OBJECTIVETo evaluate the effect of techniques of precise liver surgery for donor hepatectomy in living donor liver transplantation.

METHODSEighty-nine donors aged from 19 to 57 years were performed by the same surgical team from June 2006 to December 2013 in Chinese People's Liberation Army General Hospital.Individualized surgical program were developed according to preoperative imaging examination and hepatic functional reserve examination. The evaluation included liver function, liver volume, vascular anatomy and bile duct anatomy. According to the results after the operation, preoperative evaluation accuracy, postoperative donor liver function and postoperative complications were analyzed. ANOVA analysis was used to compare the difference of graft volume by two-dimensional, three-dimensional calculation method and actual postoperative graft weight. Pearson correlation test and linear regression analysis were used to verify the correlation between the estimated graft volume each method and actual graft postoperative weight.

RESULTSAll the 89 cases operation protocol as following, there were 5 cases with left lateral lobe graft, 10 cases with left lobe liver graft, 74 cases with right lobe graft. There were 59 cases with middle hepatic vein (MHV) harvested, and 30 cases without MHV. The mean graft volume by two-dimensional, three-dimensional calculation method and actual postoperative graft weight were (656.2±134.1) ml, (631.7±143.2) ml and (614.5±137.7) ml respectively. ANOVA analysis results showed that there were no statistically significant difference in the three methods (P>0.05). Compared to the actual postoperative graft weight, the average error rate of the two methods were 7.9% and 5.3% respectively. Pearson correlation test showed the graft volume calculated by two-dimensional and three-dimensional methods had a significantly positive correlation with actual graft weight (r=0.821, 0.890, P<0.01) and linear regression analyze showed the R2 were 0.674 and 0.792, respectively. The accuracy rate of preoperative evaluation about portal vein, hepatic vein, hepatic artery and bile duct were 100%, 100%, 97.8% and 95.5%, respectively. The preoperative plan and postoperative practical scheme coincidence rate was 95.5%. Overall donor complication rate was 7.4%. All donors were alive. Sixteen donors received right lobe hepatectomy with gallbladder preserved had a good liver function and gallbladder function.

CONCLUSIONThrough the precise preoperative evaluation, surgical planning, fine operation and excellent postoperative management, precise liver surgery technique can ensure the safety of donor in living donor liver transplantation.

OBJECTIVETo evaluate the outcome of patients with irresectable hilar cholangiocarcinoma undergoing orthotopic liver transplantation (OLT) and to identify the prognostic factors that could influence survival.

METHODSThe data of 18 patients who underwent OLT for irresectable hilar cholangiocarcinoma between June 2003 and October 2010 were analyzed retrospectively. There were 12 male and 6 female cases with median of 52 years(range from 34 to 65 years).Fifteen patients underwent modified piggyback liver transplantation, 2 patients underwent classical orthotopic liver transplantation and 1 patient underwent living donor liver transplantation. Data were evaluated regarding tumor size, pathologic stage, overall survival, recurrence rates and prognostic factors.

RESULTSOLT with lymphadenectomy was received by 18 patients with hilar cholangiocarcinoma. Median time until tumor recurrence was 20.5 months(range from 6.0 to 33.0 months). Seventeen patients died during follow-up.Of these, 14 patients died from recurrent or metastatic diseases, 2 patients died from multiple organ dysfunction syndrome during peri-operative period, and one patient died from other cause. The median survival time was 29.5 months(range from 3.0 to 84.0 months). The overall survival rate and recurrence-free survival rate at 1, 3, and 5 year were 16/18, 8/18, 1/18 and 13/18, 2/18, 1/18, respectively.Lymph node metastases had a statistically significant negative impact on overall survival. The 1, 3, and 5 year survival rates were 6/7, 1/7,0 and 10/11, 7/11, 1/11 (P < 0.05) in lymph node-positive and lymph node-negative patients.

CONCLUSIONSAcceptable survival rates can be achieved by OLT for irresectable hilar cholangiocarcinoma without lymph node metastases.Strict patient selection plus multimodal chemoradiation therapy prior to OLT are recommend for patients with lymph node metastases.
