ABSTRACT
Objective:To investigate the expression levels of silent information regulator 1 (SIRT1), hypoxia-inducible factor-1α (HIF-1α) and mutant P53 proteins in colorectal adenocarcinoma tissues and their clinical significances.Methods:The data of 68 cases of colorectal adenocarcinoma confirmed by pathology in Shanxi Traditional Chinese Medical Hospital from March 2015 to October 2021 were collected. The expressions of SIRT1, HIF-1α and mutant P53 proteins in colorectal adenocarcinoma tissues and paracancerous tissues were determined by immunohistochemistry. The correlation among SIRT1, HIF-1α and mutant P53 proteins and their relationship with clinicopathological features of patients were analyzed.Results:Among 68 colorectal adenocarcinoma tissues and paracancerous tissues, SIRT1 protein was positive in 38 cases (55.88%) and 11 cases (16.18%) ( χ2 = 23.25, P < 0.001), HIF-1α protein was positive in 47 cases (69.12%) and 5 cases (7.35%) ( χ2 =54.92, P < 0.001), and mutant P53 protein was positive in 41 cases (60.29%) and 0 cases (0) ( P < 0.001). The positive expression rate of SIRT1 protein was high in patients with high clinical stage and lymph node metastasis (both P < 0.05); the positive expression rate of HIF-1α protein was high in patients with poor differentiation ( P < 0.05); the positive expression rate of mutant P53 protein was high in patients with poor differentiation and lymph node metastasis (both P < 0.05). There was a negative correlation between expressions of SIRT1 and mutant P53 proteins ( rs = -0.38, P = 0.001); there was a positive correlation between expressions of HIF-1α and mutant P53 proteins ( rs = 0.56, P < 0.001); there was a negative correlation between expressions of SIRT1 and HIF-1α proteins ( rs = -0.40, P = 0.001). Conclusions:SIRT1, HIF-1α and mutant P53 proteins are highly expressed in colorectal adenocarcinoma and are correlated with clinicopathological features suggesting poor prognosis. Combined detection of the three proteins may be used for the diagnosis and prognosis of colorectal adenocarcinoma and serve as a new target for treatment.
ABSTRACT
Objective:To explore the correlation of c-MET and CXCR4 proteins and microvessel density (MVD) with liver metastasis in colorectal cancer tissues.Methods:A total of 40 colorectal cancer tissue samples and 10 paracancerous (5 cm from the edge of the tumor) normal colorectal tissue samples were collected from March 2015 to December 2020 in Shanxi Traditional Chinese Medical Hospital. Among 40 patients with colorectal cancer, 15 patients had liver metastasis. Immunohistochemistry was used to detect c-MET protein, CXCR4 protein and CD34-labeled MVD in various tissues, and the relationships between them and liver metastasis and between the three were analyzed.Results:The positive rates of c-MET protein [72.5% (29/40) vs. 30.0% (3/10)], CXCR4 protein [47.5% (19/40) vs. 10.0% (1/10)] and MVD (20.1±5.2 vs. 11.5±4.3) in colorectal cancer tissues were higher than those in paracancerous tissues, and the differences were statistically significant (all P < 0.05). The positive rates of c-MET protein [86.7% (13/15) vs. 64.0% (16/25)] and CXCR4 protein [66.7% (10/15) vs. 36.0% (9/25)] in colorectal cancer liver metastasis group were significantly higher than those in non-liver metastasis group, and the differences were statistically significant (both P < 0.05). MVD in colorectal cancer liver metastasis group was significantly higher than that in non-liver metastasis group (21.5±5.3 vs. 12.4±5.7), and the difference was statistically significant ( P < 0.05). In colorectal cancer tissues, c-MET protein expression was positively correlated with CXCR4 protein expression ( r = 0.568, P < 0.05), and MVD in c-MET-positive patients or CXCR4-positive patients was higher than that in negative ones (both P < 0.05). Conclusions:The c-MET protein, CXCR4 protein and MVD may play important roles in the liver metastasis of colorectal cancer. The three indicators can provide a certain reference for the early diagnosis and prognosis prediction of liver metastasis of colorectal cancer.
ABSTRACT
Objective To observe the clinical efficacy and safety ofZhilou Lotion combined with modified Sihuang Ointment in treatment of anal cryptitis.MethodsOne hundred patients with anal cryptitis were randomly divided into observation group and control group, with 50 cases in each group. The control group was given propylene dispersible tablets oral and topicalHuazhi embolism. The observation group received steaming and hip bath with Zhilou Lotion combined with modifiedSihuang Ointment topical external application treatment, 7 days as a course of treatment and 2 courses successive. The TCM syndrome scores of two groups were compared before and after treatment to evaluate the clinical efficacy. The remission time of symptoms, hospitalization time, recurrence rate in 6 months and adverse reactions were observed.Results After treatment, the TCM syndrome scores of two groups were improved (P<0.01), and the scores in the observation group was lower than those in the control group (P<0.01). The total effective rate was 96.0% (48/50) in the observation group, and 80.0% (40/50) in the control group, with statistical significance (P<0.01). The remission time of anal edema, anal dampness, anal pain and anal fall-swell in observation group was obviously shorter than that in the control group, with statistical significance (P<0.01). The average hospitalization time was (15.25±2.78) days in the observation group and (18.46±3.41) days in the control group, the difference was significant (P<0.01). In the observation group, the recurrence rate was 0, 0 and 2.0% in 2, 4, 6 months follow-up, while that was 4.0%, 12.0% and 16.0% in the control group, respectively. The recurrence rates of the control group in 4 months and 6 months were higher than those of the observation group (P<0.05). No significant adverse reactions occurred in the two groups.Conclusion Zhilou Lotion combined with modifiedSihuang Ointment has good clinical efficacy in treatment of anal cryptitis, with low recurrence rate and high safety.
ABSTRACT
OBJECTIVE:To observe the curative effect of Zhenggu qutong tincture on acute soft tissue injury. METHODS:140 cases of acute soft tissue injury were treated with Zhenggu qutong tincture (treatment group) and Xiaoshangtong linimentum (control group) for 6 times each day (interval of 2 h) with cure course of seven days. The total effective rate and obvious effective rate were observed while the improvement of symptoms such as pain, tenderness, swelling, dysfunction and ecchymosis were also determined.
