Objective To explore the characteristics of traditional Chinese medicine(TCM)syndromes in patients with cervical high-risk human papillomavirus(HR-HPV)infection,and to provide reference for clinical syndrome differentiation and treatment of cervical HR-HPV patients.Methods From September 2020 to October 2022,the TCM syndrome manifestations of cervical HR-HPV infection diagnosed by HPV detection in the Gynecology Department of The Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine were investigated,and then the distribution of disease-location syndrome elements,disease-nature syndrome elements and syndrome types was analyzed.Results The patients with cervical HR-HPV infection were usually manifested with abnormal vaginal secretions,which accounted for 63.40%.The disease-location syndrome elements of cervical HR-HPV infection were uterus,spleen,liver,kidney,meridians,stomach,heart spirit and heart.Among them,uterus,spleen and liver were most commonly-seen,accounting for 67.00%,58.80%and 55.80%respectively.The disease-nature syndrome elements were dampness,heat,qi stagnation,blood stasis,qi deficiency,yang deficiency,yin deficiency,phlegm and cold.Among them,dampness,heat,qi stagnation and blood stasis were most commonly-seen,accounting for 66.40%,56.60%,36.00%and 31.80%,respectively.In various age groups of the infected patients,the uterus was the predominated disease-location syndrome element,and dampness and heat were the predominated disease-nature syndrome elements.The uterus-spleen was the predominated double disease-location syndrome element,and the uterus-spleen-liver was the predominated triple disease-location syndrome element.Damp-heat was the predominated double disease-nature syndrome element,and damp-heat-blood stasis was the predominated triple disease-nature syndrome element.According to the results of cluster analysis and with reference to the clinical practice,it was found that the main syndrome types of the patients with cervical HR-HPV infection were damp-heat stasis stagnation,liver depression and qi stagnation,heart-kidney incoordination,spleen-stomach yang deficiency.Conclusion In the view of the TCM syndrome,cervical HR-HPV infection is mainly affected with the uterus,and also involves the spleen,liver and kidney.The disease-nature syndrome elements are characterized by dampness and heat,showing the characteristics of deficiency interweaved with excess.The main TCM syndrome types are damp-heat stasis stagnation,liver depression and qi stagnation,heart-kidney incoordination,and spleen-stomach yang deficiency.

OBJECTIVETo investigate the pathological feature of primary hepatic carcinoma and the clinical significance.

METHODSFrom August 2000 to December 2007, there were 89 patients with cirrhosis and carcinoma of liver who accepted whole liver resection. The whole liver was cut into 10 mm slices to examine the tumor size, number, distribution, capsule, satellite nodes, portal vein tumor thrombi (PVTT). The invaded adjacent tissue and lymph nodes were recorded, the distance from satellite to major tumor was measured, then histological examinations were carried out, and the final diagnosis was made by pathologists.

RESULTSThe total of 89 cases included hepatocellular carcinoma in 86 cases and cholangiocarcinoma in 3 cases; 53 cases with multiple tumors and 36 cases with solitary tumor; complete capsule only in 14 cases, no obvious margin in 11 cases, 13 cases had a major tumor in the right lobe and a small tumor in the left lobe; 8 of 25 cases with gross invaded tissue were confirmed by histological examination, 7 of 16 cases with swollen lymph nodes were infiltrated by cancer cells. There were 47 cases with PVTT (47.2%) and 39 cases with satellite nodes (43.8%). PVTT and satellite nodes increased with the increase of sizes and the numbers of the tumors. The distance from satellite node to major tumor mostly were 0.5 - 3.0 cm.

CONCLUSIONSThe whole explanted liver can completely reflect the characteristics of growth and infiltration of hepatic carcinoma. Attention must be paid to the small cancer lesions in another lobe, distal satellite nodes from major tumor, and tumor thrombi in a small branch of portal vein, which can not be found by imaging, and might influence the curative effectiveness after liver resection or transplantation.

OBJECTIVETo investigate the value of liver transplantation for late hepatocellular carcinoma.

METHODSThirty-six patients were treated by liver transplantation from August 2000 to February 2002, of which 15 patients had had advanced hepatocellular carcinoma and thirteen of these 15 patients were evaluated for results.

RESULTSThe 1-year survival rate was 86% (6/7). Only one patient died of recurrence within 6 months. The tumor-free survival was 5 to 19 months. Till February 2002, two patients have survived for 10 months and 19 months with recurrence.

CONCLUSIONIn our country, if the patients can afford liver transplantation, advanced hepatocellular carcinoma without extrahepatic metastasis is still indicated for liver transplantation, since some patients may survive relatively long.

OBJECTIVETo investigate the feasibility, reliability and therapeutic effectiveness of adjuvant chemotherapy for advanced hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT).

METHODSThe clinical data of adjuvant chemotherapy after OLT in 10 advanced HCC patients were studied retrospectively. FAP chemotherapy regimen was adopted calcium folinate (CF) 200 mg/m(2) and 5-Fluorouracil 500 mg/m(2) iv on D1 to D5, and doxorubicin 40 mg/m(2), cisplatin 30 mg/m(2) iv on D1, with 28 days as a cycle. The opportune time of chemotherapy, chemotherapy regimen, synergistic action between cytotoxic agent and immunosuppressive agent on liver and kidney and side-effects were preliminarily evaluated.

RESULTS7/10 patients are surviving, with the longest survival of 32 months, and the shortest 9 months. Three patients died after operation, two at 13 months, one at 20 months after OLT, all died of metastasis. The incidence of one year survival was 9/9. During the period of chemotherapy, the side-effects of adjuvant chemotherapy were moderate.

CONCLUSIONChemotherapy which is able to prolong the life-span of patients with advanced HCC after orthotopic liver transplantation is feasible and effective, the side-effects were mild. The choice of opportune time of chemotherapy might influence the outcome.

LPS stimulation of macrophages production of IFN-beta plays a key role in innate immunity defending the microbial invasion. In this study, the effect of S632A3 promoting LPS-induced IFN-beta production and the underlying mechanism were investigated, mRNA level was measured by real-time PCR, cytokine production was determined by ELISA, GSK-3beta activity was investigated by kinase assay, protein phosphorylation and expression were evaluated by Western blotting. The results revealed that S632A3 significantly augmented IFN-beta production by LPS-stimulated macrophages. S632A3 inhibition of the activation of GSK-3beta, reduced the threonine 239 phosphorylation of transcription factor c-Jun but increased the total level of c-Jun in LPS-stimulated macrophages. Moreover, small interfering RNA-mediated knockdown of c-Jun level abrogated the ability of S632A3 to augment IFN-beta. The study thus demonstrates S632A3 being a new anti-inflammation lead compound and provides a molecular mechanism by which S632A3 promoted LPS-induced IFN-beta production in macrophages through inhibiting the activation of GSK-3beta.

OBJECTIVETo analyze the risk factors for acute renal failure (ARF) early after liver transplantation.

METHODSThe data of 362 patients undergoing liver transplantation from August 2000 to December 2010 were retrospectively analyzed, including 71 patients with ARF (ARF group) and 291 without ARF (non-ARF group). Thirty-six variables, including clinical and experimental variables, were analyzed by t test for continuous variables and χ(2) test for discrete variables. The variables with significance (P < 0.05) were then analyzed with Stepwise logistic regression.

RESULTSTwelve variables, including pretransplant serum creatinine, hemoglobin, thrombinogen activity, total bilirubin, MELD scores, total operation time, intraoperative blood loss, intraoperative blood transfusion, preoperative urine output, preoperative hepatic encephalopathy, intraoperative low blood pressure and postoperative infection, had significant difference between two groups (F = 10.30 - 182.70, P = 0.000 - 0.041). The Stepwise logistic regression analysis for 12 variables demonstrated that the high level of pretransplant serum creatinine, the low pretransplant thrombinogen activity, the high MELD scores, the large volume of intraoperative blood loss, postoperative infection were the independent risk factors of ARF complicated to orthotopic liver transplantation (P < 0.05).

CONCLUSIONSEarly ARF is a key negative factor for the survivors after orthotopic liver transplantation. The reason for ARF complicated to OLT is multiple. The high level of pretransplant serum creatinine, the low pretransplant thrombinogen activity, the high MELD scores, the large volume of intraoperative blood loss, postoperative infection were the independent risk factors of ARF complicated to orthotopic liver transplantation.

OBJECTIVETo discuss the relevant factors of biliary complications after liver transplantation and to investigate the value of comprehensive management for the complications.

METHODSThe data of 366 patients undergoing liver transplantation from October 2000 to March 2012 was analyzed retrospectively, and the risk factors were analyzed by univariate analysis and Stepwise Logistic regression. The cases with biliary leak were administered thorough drainage. The cases with anastomotic biliary stricture were administered sacculus dilatation through percutaneous transhepatic cholangiography (PTC) and endoscopicretrograde cholangiopancreatography (ERCP). If necessary, some cases were placed biliary tract brackets. The patients with nonanastomotic biliary stricture were treated with PTC plus choledochoscope.

RESULTSAll the 366 patients were followed up for 58.5 (10 to 129) months. Biliary complications after liver transplantation were diagnosed in 42 cases among these patients. The incidence for biliary complications was 11.5%. The univariate analysis and multivariate Logistic regression analysis showed that the second warm ischemia period and the blood loss and the damage of blood supply and the diameter of biliary anastmosis were significantly associated with biliary complications after liver transplantations (Wald = 9.474 to 17.208, P < 0.05). Twelve cases with biliary leak were cured through abdominal and nasobiliary drainage. Twenty-two cases with anastomotic biliary stricture were administered sacculus dilatation through ERCP or PTC and were cured, including 6 cases were placed biliary tract brackets. Among 8 cases with nonanastomotic biliary stricture, 6 cases were cured through PTC associating with choledochoscope. One case was treated second liver transplantation and another case got worse.

CONCLUSIONSIschemic injury and the diameter of anastmosis are risk factors for biliary complications after liver transplantations. The interventional management of biliary stricture and bile leakage after liver transplantation is safe and effective.

OBJECTIVETo compare the clinical effect of Chinese medicine (CM) and Western medicine (WM) for controlling the recurrence of pelvic endometriosis after a conservative operation.

METHODSThe study was a multi-center, randomized, parallel controlled and prospective clinical trial. Patients were randomly divided into two groups: CM group (106 cases) and WM group (102 cases). Drugs were given to patients during 1-5 days of the first menstruation after a conservative operation in both groups. Patients with stages I and II (revised American Fertility Society) were treated for 3 months, while the patients with stages III and IV were treated for 6 months. The patients in the CM group were treated using three types of Chinese herbal medicine based on syndrome differentiation. Patients in the WM group were treated using gonadotropin releasing hormone agonist (GnRH-a) or gestrinone. Patients treated with GnRH-a received add-back therapy of Tibolone Tablets once a day after 4 months of treatment. Any cases of dysmenorrheal chronic pelvic pain, menstruation and any adverse reactions of patients were recorded once a month during the preoperative and postoperative periods and once every 3 months during the follow-up period. During the preoperative, postoperative and the follow-up periods, patients underwent type B ultrasonography of the pelvis and measurements of serum CA125 levels, gynecologic examination, routine evaluations of blood, urine, hepatic function (glutamate pyruvate transaminase), renal function (blood urea nitrogen) and electrocardiograms. During the follow-up period they underwent type B pelvic ultrasonography, measurement of serum CA125 levels and further gynecologic examinations. The two treatments were compared for clinical recurrence rates, pregnancy rates and the incidence of adverse reactions.

RESULTSThe incidence and timing of recurrence of endometriosis were not significantly different between the two groups. The first pregnancy achieved by the patient in the CM group was significantly earlier than that in the WM group (P <0.05). Moreover, the incidence of adverse reactions in the WM group was significantly higher than in the CM group (P <0.01).

CONCLUSIONSTreatment with Chinese herbal medicines prevented the recurrence of endometriosis after a conservative operation, improved the conception rate and showed fewer and lighter adverse reactions than did treatment with WM therapy. Treatment with Chinese herbal medicine meets the need of patients wishing to have a child following endometriosis and is an appropriate form of clinical treatment.
