ABSTRACT
Objective:To investigate the clinical value of indocyanine green (ICG) staining technique combined with laparoscopic hepatectomy with a Glisson pedicle approach in the treament of liver cancer.Methods:The clinical data of 150 patients with primary liver cancer, who received treatment in Yuyao People's Hospital from January 2019 to December 2020, were retrospectively analyzed. Group A ( n = 82) and group B ( n = 68) were designated according to the surgery methods used. The group A was subject to laparoscopic hepatectomy with a Glisson pedicle approach. The group B received ICG staining technique combined with laparoscopic hepatectomy with a Glisson pedicle approach. Operation-related conditions, postoperative complications, and the change in liver function indexes after surgery relative to before surgery were compared between the two groups. Results:There were no significant differences in the time taken to first anal exhaust, extubation time, and length of hospital stay between group A and group B (all P > 0.05). Operative time and intraoperative bleeding in the group B were (205.04 ± 35.01) minutes and (230.05 ± 17.53) mL, respectively, which were significantly lower than those in the group A [(228.07 ± 28.05) minutes, (255.07 ± 19.00) mL, t = 4.47, 8.31, both P < 0.05]. R0 resection rate was significantly lower in group B than in group A [85.29% (58/68) vs. 70.73% (58/82), χ2 = 4.50, P < 0.05]. There were no significant differences in postoperative complications between the two groups ( P > 0.05). Before treatment, there were no significant differences in serum levels of alanine aminotransferase (ALT), aspartate transaminase (AST), and total bilirubin between the two groups (all P > 0.05). At 1 day after surgery, serum ALT, AST, and TBil levels in each group were significantly increased compared with before surgery (all P < 0.05). Furthermore, serum levels of ALT, AST and TBil in the group A were (108.51 ± 30.23) U/L, (107.66 ± 26.93) U/L, and (32.16 ± 4.73) μmol/L, respectively, which were significantly higher than those in the group B [(88.38 ± 24.76) U/L, (86.85 ± 19.74) U/L, (27.95 ± 4.31) μmol/L, t = 4.40, 5.30, 5.65, all P < 0.05]. At 3 days after surgery, serum levels of ALT, AST, and TBil in each group were significantly lower than those at 1 day after surgery, but they were still higher than those before surgery. At 3 days after surgery, serum levels of ALT, AST and TBil in group A were (74.20 ± 13.83) U/L, (65.22 ± 9.68) U/L, and (28.18 ± 4.14) μmol/L, respectively, which were significantly higher than those in group B [(54.72 ± 10.31) U/L, (55.41 ± 7.63) U/L, (24.25 ± 3.98) μmol/L, t = 9.61, 6.79, 5.89, all P < 0.05]. Conclusion:Although the ICG staining technique has certain limitations, it can improve the accuracy of hepatectomy to a certain extent. ICG staining technique combined with laparoscopic hepatectomy with the Glisson pedicle approach is a safe and accurate treatment for liver cancer. The combined therapy is worthy of clinical application.
ABSTRACT
Objective To assess the effect of magnetic resonance imaging (MRI) on preoperative staging of endometrial carcinoma and depth of myometrial invasion. Methods Fifty-six patients with endometrial carcinoma were underwent conventional and contrast-enhanced MR scan. The results of pathology , MRI examinations of preoperative staging and depth of myometrial invasion were assessed and compared. Results The accurate rate of MRI diagnosis in preoperative staging diagnosis was 82.1% (46/56) and the consistency check as Kappa was 0.771 (P < 0.001). Conclusions MRI may be a good diagnostic tool with high sensitivity and specificity for assessing myometrial invasion and detecting tumour extension and should be considered as a routine part of the preoperative assessment in all patients with endometrial carcinoma.
ABSTRACT
Objective To investigate the infection status of HIV/AIDS patients complicated with pneumocystis Carinii Poneumonia(PCP),and the role of CD4+ T lymphocyte in PCP.Methods PC was detected by Giemsa's staining and CD4+ T lymphocyte was counted by flow cytometry.Meanwhile,this text calculated and compared a series of indexes about PC infection,such as the total positive rate,the average annual positive rate,the average monthly positive rate,the positive rate between female and male,the positive rate between sputum and BALF specimens,and the relationship between the positive rate and CD4+ T lymphocyte count.Results The total positive rate about PC infection of the 1 806 eases of sputum specimens was 46.8％,and the incidence mainly from April to July during a year,and the positive rates were 46.3％ and 50.2％ for males and females respectively.The results showed that there were no significant differences when compared with the average annual positive rate ( P ＞ 0.05 ),but there were significant differences when compared with the average monthly positive rate ( P ＜ 0.05 ),the positive rate between female and male(P＞0.05),and among 3 formerly defined ranges of CD4+count(P ＜0.05).Conclusion Giemsa's staining showed the total positive rate was 46.8％ of the HIV/AIDS patients infected by PC with sputum specimens,which represented a seasonal fluctuation tendency.The positive rate of BALF was higher than that in sputum,and it increased with CD4+ count decreasing.Giemsa's staining was an efficient,simple and feasible way for PC detection and easy for generalization.Meanwhile,it is strongly relied on the operator's experience and skill.
ABSTRACT
Fibro-optic bronchoscopy (FB) examinations were undertaken in 42 cases with lung cancer and 25 cases with benign lung disease; methylation-specific PCR was performed in plasma, sputum and bronchoalveolar lavage fluid (BALF) specimen for detection of p16 gene promoter methylation in all patients.Of the 42 cases of lung cancer, the positive rates of p16 gene promoter methylation were 59.5% in BALF, 52.4% in plasma and 47.6% in sputum, respectively; while p16 gene promoter methylation was detected only in one plasma sample from 25 cases with benign lung disease ( P ＜ 0.05 ).The sensitivity,specificity and overall accuracy of FB were 59.5%, 100.0% and 74.6%, respectively.The sensitivity,specificity and overall accuracy of FB combined with aberrant p16 gene methylation in diagnosis of lung cancer were 92.9%, 96.2% and 94.0%, respectively.The FB examinations combined with detection of aberrant p16 gene methylation can further improve the accuracy to diagnosis of lung cancer.

ABSTRACT
Objective To investigate the effects of HRT on endometrium of postmenopausal women.Methods 53 cases of postmenopausal vaginal bleeding(PMB),from Jan,1995 to Dec.1999 treated by HRT were selected to make a comparison with the other 60 cases of PMB without HRT during the corresponding period.Both groups had integrated ultrasonic and pathological data and getting information from succedent inspection.Results The rates of the endometrial carcinorma incidences that happen in the HRT group were non-HRT group were 5 66% and 8 33% respectively,which had little significant.While the occurring rates of inflammation were 1 89% and 16 67% respectively,a significant difference between the both existed here.Conclusions With HRT,the various symptoms of post menopause women can be efficiently improved.It is safe and effective in short term.But a close monitoring is absolutely necessary for its long term effect(5 years or more).
ABSTRACT
AIM:To investigate the aberrant methylation in the promoter of p16 in plasma,sputum,bronchoalveolar lavage fluid(BALF),pleural effusion and biopsy specimens from suspected lung cancer patients and to evaluate the clinical significance in the early diagnosis of lung cancer.METHODS:Using methylation specific PCR(MSP)for the detection of promoter methylation of p16 gene in plasma,sputum,BALF,pleural effusion and biopsy specimens from suspected lung cancer patients.RESULTS:Of the 67 cases of suspected lung cancer patients,42 were proved by pathology.The positive percentages of p16 gene promoter methylation of the lung cancer patients are as follows:52.4%(22/42)in plasma,47.6%(20/42)in sputum,59.5%(25/42)in BALF,71.4%(10/14)in pleural effusion and 61.9%(26/42)in biopsy specimens,respectively;while promoter methylation in p16 gene was found only one in plasma and one in pleural effusion in 25 patients with various benign lesions(P0.05).CONCLUSION:Detection of the aberrant methylation in the promoter of p16 gene in plasma,sputum,BALF,pleural effusion and biopsy specimens from lung cancer patients by MSP method is a kind of rising technology with development potential for lung cancer early diagnosis.
