Objective:To study the relationship between preoperative serum carbohydrate antigen 19-9 (CA19-9) levels and long-term prognosis after partial hepatectomy in patients with hepatocellular carcinoma (HCC).Methods:The clinical data of 1102 patients with HCC who underwent partial hepatectomy at the Affiliated Tumor Hospital of Guangxi Medical University from January 2012 to December 2017 were retrospectively analyzed. There were 960 males and 142 females, with an average age of 51 years. The X-tile software determined the best cut-off value of CA19-9 to be 55U/ml. The enrolled patients were then divided into the low-level (CA19-9≤55 U/ml, n=956) and high-level (CA19-9 >55 U/ml, n=146) groups. The Kaplan-Meier method was used to analyze survival, and the log-rank test was performed to evaluate survival rates. The prognostic risk factors of HCC were calculated by the Cox proportional hazards model. Results:The 1, 3, and 5-year survival rates for the low-level group were 85.0%, 68.2%, and 60.9%, respectively, which were significantly higher than those of the high-level group of 80.1%, 58.2%, and 47.0%, respectively ( P<0.05) . The 1, 3, and 5-year recurrence-free survival rates of the low level group were 60.5%, 44.6%, and 37.9% respectively, which were significantly higher than those in the high-level group of 53.4%, 33.3%, and 25.1%, respectively ( P<0.05). Cox regression analysis showed that patients with CA19-9 >55 U/ml ( HR=1.323, 95% CI: 1.070-1.636, P=0.010) had a higher risk of recurrence after hepatectomy, while patients with CA19-9 >55 U/ml ( HR=1.511, 95% CI: 1.163-1.964, P=0.002) had a poor prognosis after hepatectomy. Conclusions:Preoperative serum level of CA19-9>55 U/ml was an independent risk factor for survival and recurrence of HCC patients after partial hepatectomy. CA19-9 had a significant predictive value for prognosis of HCC patients who underwent partial hepatectomy.

Objective To compare the efficacy of CO2 laser and conventional laryngeal microsurgery in the treatment of benign lesions of vocal cord (polyp of vocal cord) and precancerous lesions (leukoplakia of vocal cord) of patients. Methods A total of 60 patients with vocal cord polyps were selected, and randomly divided into two groups, each with 30 patients. Thirty patients with vocal cord leukoplakia were selected and randomly divided into two groups, each with 15 patients. One group was performed by cold instruments for lesion resection (conventional group), the other by CO2 laser for removal of diseased tissue or mucosal ablative surgery (laser group). Two groups of patients were examined by laryngostroboscope, electronic laryngoscopy, GRABS, VHI subjective ratings and objective voice analysis before operation and one week, one month and three months after operation. ResuIts The outcomes of those with vocal cord polyps in early recovery (1 week) laser group were slightly worse than the conventional group. In later recovery (1~3 months), with electronic laryngoscopy inspection, laryngostroboscope mucosal wave observation, the analysis of subjective and objective data from the two groups showed no significantly differences. For patients with vocal cord leukoplakia in early recovery (1 week), laser group slightly worse than the conventional group, in later recovery (1~3 months), there were no obvious difference between the two groups in electronic laryngoscopy inspection, laryngostroboscope mucosal wave observation, the analysis of subjective and ob_jective data. Follow -up operations, the recurrence rates in laser group was significantly lower than conventional group. ConcIusion The treatment by CO2 laser can significantly improve their pronunciation quality for vocal cord polyps and vocal cord leukoplakia patients, it has a good therapeutic effect, especially the long-term effective of vo_cal cord leukoplakia is better than conventional operation.

This article was aimed to study the general reproductive toxicity in mice in order to give a better evalua-tion of the medicinal plant of pineapple leaves (A nanas comasus L). Adult male and female mice were orally admin-istered with pineapple leaves. And then, each of the male and female mice was put together in one cage for mating. The mating success females were fed continuously. The experimental observation was conducted in pregnancy, fetal development, as well as the offspring of mice. The results showed that in addition to a large dose of pineapple leaves (4 g·kg-1) of the parental male rats having a lower body weight, pineapple leaves did not significantly affect on other parameters. There were no significant effects on pregnant mice and their offspring of mice. It was concluded that the pineapple leaves did not influence the general reproductive function of mice apparently.

Objective To explore the effect of quality control circles (QCCs) in improving the delivery health checkup report.Methods QCC was founded with the theme of"improving the quality of health checkup report delivery."First,we planned an activity schedule and identified topics.We then set target focuses for service personnel,distribution modes,and operating environments;planned countermeasures;and selected optimal policies.Circle members implemented the optimal policies jointly.Reports of physical examinations by the Guoyu health management center were selected and analyzed.The total number of reports before improvement (January to December 2015) was 59 189 of which 34 549 (58.4％) were male patients and 24 640 (41.6％) were female patients;their average age was (37.7± 11.4) years.The total number of reports after improvement (December 2016 to January 2017) was 6 568,of which 3 881 (59.1％) were male patients and 2 687(40.9％) were female patients;their average age was (39.9± 11.7) years.We compared the quality indicators and evaluated the comprehensive quality of the patients before and after improvement.A total of 65 531 physical examination reports of subjects examined at the center between February and December 2017 were selected for effect tracking,including 39 230 (59.9％) men and 26 301(40.1％) women,aged (38.1±11.5).Results The on-time delivery rate of the health examination reports from rose from 51.4％ to 94.0％.The ratio of system leakage to sign for reports decreased from 14.5％ to 0.8％.The average time between the examination and when each report was handed over to for distribution decreased from 29.8 hours to 4.2 hours,and the average time between each report being distributed to the providers checking in dropped from 509.8 hours to 72.8 hours,while the average time for the preparation of each report for delivery decreased from 13.5 seconds to 3.1 seconds.The average time between delivery of a report and its being signed decreased from 4.3 seconds to 0.1 seconds.Before the improvement,the expected goals were not met.After improvement,the delivery rate of the health examination reports was 100.0％,the delivery intact rate of the group reports was 100.0％,and the satisfaction rate of the group reports was 99.4％.The comprehensive quality for the members was obviously higher after the improvement than before.After 11 months of tracking,the delivery accuracy rate of health examination report still failed to reach the target value of 100.0％,but all other indicators reached the target value,with good results.Conclusions Application of QCC not only improved the delivery the health checkup reports,but also promoted service quality after medical examinations and ended medical dispute caused by the loss of physical examination reports.

Clonorchis sinensis is considered a class I carcinogen for cholangiocarcinoma, but an increasing number of studies have found that it is also closely associated with hepatocellular carcinoma. This paper reviews the discovery and prevalence, historical studies, key regional studies, animal models and complications of Clonorchis sinensis, and summarizes the possible molecular mechanisms of Clonorchis sinensis contributing to hepatocellular carcinoma development, in order to gain insight into the correlation between Clonorchis sinensis and hepatocellular carcinoma, and thus to provide new ideas for the study of the effects of Clonorchis sinensis infection on hepatocellular carcinoma.

OBJECTIVETo study the allergen in key processes during the production of Fufang Kushen injection by IgG promoter-HepG2 cells in vitro.

METHODBy transfecting a IgG promoter-regulating the expression of green fluorescent protein(GFP) plasmid into HepG2 cells, this transferred cells were incubated with common allergens (like puerarin, ovalbumin, LPS or Sal typhoid vi polysaccharide vaccine), excipients using in Fufang Kushen injection (NaOH, acetic acid, Tween-80 and ethanol) and samples from the key production processes of the injection for 30 minutes . Fluorescent photographs were analyzed the fluorescence intensity of the cells by using an image analysis software.

RESULTAll of common allergens significantly increased the IgG expression. Two of the excipicents, acetic acids and Tween-80 were shown to increased the IgG expression, while others had no effect on IgG expression. In the 8 samples from the key processes in the production of Fufang Kushen injection, two of them stimulated IgG expression.

CONCLUSIONIgG promoter-HepG2 cells are highly sensitive and specific to allergens, and thus can be applied to rapid screening of allergens in components and injections in transcriptional level. It is possible to use the IgG-promoter HepG2 cells in a real-time monitoring of allergens in the production processes of Chinese medicine injections.

The onset of primary hepatic carcinoma (PHC) is usually occult, and early symptoms are not obvious. Most patients are at advanced stages of disease at diagnosis, and the prognosis is poor. Paraneoplastic syndrome (PNS) refers to the clinical manifestations indirectly caused by tumor metabolites or abnormal immune reactions that cannot be explained by the primary lesion, local tumor spread or distant metastasis. Hypercholesterolemia, hypercalcemia and hypoglycemia are the most commonly seen clinical presentations of PNS in PHC patients. Adequate understanding of PNS is of great importance in early diagnosis and treatment of PHC. In this review, we summarized the clinical manifestations and prognostic mechanisms of PNS in patients with PHC.
