Objective To evaluate argon-helium cryoablation combined with transcatheter arterial chemoembolization (TACE) in treating primary hepatocellular carcinoma by comparing the changes of AFP level and T cell immunity after the therapy with that obtained after the treatment of argon-helium cryoablation alone and with that obtained after the treatment of TACE alone. Methods (1) Ninety-nine patients with primary hepatocellular carcinoma were randomly divided into three groups: group A (n=30), treated with argon-helium cryoablation; group B (n=34), treated with TACE; and group C (n=35), treated with argon-helium cryoablation together with TACE. The patients' gender, age and pathology of three groups were comparable with each other. (2) The peripheral blood T cell immunity and AFP level both before and after the treatment were determined and the results were statistically compared. Results After the treatment the AFP level in all 3 groups was significantly reduced when compared to that determined before the treatment (P < 0.05). And the difference in the decrease of AFP level between group C and A, also between group C and B, was statistically significant (P < 0.05). After the treatment the T cell immunity, including Th, TS and Th / TS, in all 3 groups was significantly different from that determined before the treatment (P < 0.01), and significant difference also existed between group C and A and between group C and B (P < 0.01). Conclusion The statistic analysis of AFP and T cell immunity, which are regarded as the index of therapeutic efficacy, indicates that argon-helium cryoablation combined with TACE is superior to simple argon-helium cryoablation and also to simple TACE in the treatment of primary hepatocellular carcinoma.

The incidence of locally recurrent rectal cancer is about 10%. Most patients have serious symptoms after tumor recurrence, which seriously affects the quality of life and prognosis of patients. Although it is more difficult to perform reoperation, it is still the main method to treat local recurrence of rectal cancer. At present, the main methods of reoperation include transabdominal anterior resection, combined pelvic organ resection, combined pelvic organ resection, and sacral resection. Open surgery is the main method. In recent years, with the extensive development of laparoscopic technology, laparoscopic techniques have been tried at home and abroad to perform reoperations for locally recurrent rectal cancer, showing good short-term results. The authors systematically introduce the application of laparoscopic technology in the reoperation of locally recurrent rectal cancer based on relevant research advances at home and abroad, in order to explore its clinical application prospects and promotion value.

Objective:To explore the effect of locking compressing plates (LCP) internal fixation under arthroscopy combined with Zhuyu Tongluo method in the treatment of distal radius fractures (DRF) and its effects on joint function, hemorheology, serum basic fibroblast growth factor (bFGF) and bone morphogenetic protein 2 (BMP-2).Methods:A total of 78 patients with DRF admitted to the Second Hospital of Tangshan City from June 2017 to January 2020 were selected and grouped according to the random number table method, with 39 cases in each group. The control group was treated with LCP internal fixation under arthroscopy, and the study group was treated with Zhuyu Tongluo method on the basis of the control group. The recovery, hemorheology (plasma viscosity, whole blood viscosity high cut, whole blood low cut, hematocrit), serum bFGF, BMP-2 levels, before and after the operation were compared between the two groups. They were followed up for 6 months and the range of motion of the wrist joints before and after the operation and the excellent and good rate of wrist joint function between the two groups were compared.Results:The swelling subsidence time, pain disappearance time, ecchymosis disappearance time, and fracture imaging healing time in the study group were shorter than those in the control group: (10.37 ± 3.13) d vs. (14.62 ± 3.38) d, (12.39 ± 2.97) d vs. (17.14 ± 4.02) d, (19.15 ± 2.35) d vs. (24.36 ± 3.27) d, (68.21 ± 7.12) d vs. (80.07 ± 8.24) d, and the differences were statistically significant ( P<0.05). The plasma viscosity, whole blood viscosity high-cut, whole blood low-cut, and hematocrit in the study group were lower than those in the control group at 1 and 2 weeks after operation ( P<0.05). The levels of serum bFGF and BMP-2 in the study group were higher than those in the control group at 1 and 2 weeks after operation: at 1 week after operation: (356.27 ± 46.29) μg/L vs.(236.51 ± 37.42) μg/L, (614.28 ± 61.47) μg/L vs. (487.39 ± 48.24) μg/L; at 2 weeks after operation:(502.07 ± 113.21) μg/L vs. (381.59 ± 82.75) μg/L, (910.77 ± 97.20) μg/L vs. (731.35 ± 92.13) μg/L, and the differences were statistically significant ( P<0.05). The palm flexion, back extension, radial deviation, and ulnar deviation in the study group were better than those in the control group at 6 months after operation ( P<0.05). The excellent and good rate of wrist joint function in the study group was higher than that in the control group at 6 months after operation: 89.5%(34/38) vs. 70.3%(26/37), and the difference was statistically significant ( P<0.05). Conclusions:LCP internal fixation under arthroscopy combined with Zhuyu Tongluo method in the treatment of patients with DRF can increase the expression of serum bFGF and BMP-2, reduce inflammation, improve blood rheology, promote fracture healing, and improve wrist range of motion and wrist function.

AIM:To study the protective effect of anti-aging Klotho protein on human umbilical vein endothe-lial cells (HUVECs) treated with high glucose (HG).METHODS:HUVECs were cultured in vitro, and divided into PBS control group, 5.5 mmol/L glucose group, 33.3 mmol/L glucose group, 0.1 μmol/L Klotho +33.3 mmol/L glucose group, 1 μmol/L Klotho+33.3 mmol/L glucose group , and 10μmol/L Klotho+33.3 mmol/L glucose group .The viabili-ty of the HUVECs was measured by MTT assay .The content of malondialdehyde ( MDA) , and the activities of lactate de-hydrogenase (LDH), superoxide dismutase (SOD) and glutathione (GSH) in cell culture supernatants were observed . The production of reactive oxygen species ( ROS) in HUVECs was analyzed by flow cytometry .The levels of nitric oxide ( NO) , endothelin ( ET-1 ) , intercellular adhesion molecule-1 ( ICAM-1 ) in HUVEC culture medium were detected by ELISA.The protein expression of nuclear factor-kappa B (NF-κB) in the HUVECs was determined by Western blot .RE-SULTS:Compared with PBS control group , 33.3 mmol/L glucose significantly decreased the HUVEC viability , increased ROS, LDH and MDA levels , reduced the activities of SOD and GSH , decreased the NO secretion , and induced the ET-1 and ICAM-1 secretion and the protein expression of NF-κB in HUVECs.When HUVECs were treated with Klotho protein at different concentrations combined with 33.3 mmol/L glucose, the cell viability was increased significantly , the ROS, LDH and MDA levels were decreased significantly , the antioxidant SOD and GSH activities were significantly increased , the se-cretion of NO was increased , but ET-1 and ICAM-1 releases and protein expression of NF-κB were significantly reduced . CONCLUSION:Anti-aging Klotho protein promotes the viability of HUVECs treated with HG , reduces the oxidative dam-age and ROS production , and restores the normal secretory function of HUVECs , thus playing a protective role in vascular endothelial cells through reducing the protein expression of NF-κB.

[ ABSTRACT] AIM:To study the effects of anti-aging Klotho protein on neonatal rat myocardial cells with hypo-xia/reoxygenation ( H/R) injury.METHODS:The cardiomyocytes of neonatal SD rats were cultured to establish hypoxia/reoxygenation model.The myocardial cells were divided into normal control group, H/R model group, different concentra-tions of Klotho protein (0.1μmol/L, 1μmol/L and 10μmol/L) pretreatment groups.The myocardial cells pulse frequen-cy was observed before and after H/R.The cell viability was measured by MTT assay.The leakages of LDH, CK and AST, the content of MDA and the activity of SOD were detected.The apoptotic rate of the myocardial cells was analyzed by flow cytometry.The mRNA expression of endoplasmic reticulum stress markers and apoptosis-related molecules GRP78, CRT, CHOP and caspase-12 was measured by real-time PCR.The protein levels of CHOP, caspase-12 and phosphorylated Akt in the myocardial cells were determined by Western blot.RESULTS: Compared with normal control group, the pulse fre-quency, cell viability rate and SOD activity of myocardial cells were significantly decreased, the cell apoptotic rate as well as the contents of LDH, CK, AST and MDA were increased in H/R model group.The mRNA expressions of GRP78, CRT, CHOP and caspase-12 as well as the protein levels of CHOP and caspase-12 were increased, whereas p-Akt level was decreased obviously.Compared with H/R model group, the pulse frequency, cell viability rate and SOD activity were in-creased significantly, the cell apoptotic rate as well as the contents of LDH, CK, AST and MDA were decreased in Klotho pretreated group.The mRNA expression of GRP78, CRT, CHOP and caspase-12 as well as the protein levels of CHOP and
caspase-12 were decreased, while p-Akt level increased significantly.CONCLUSION:Anti-aging Klotho protein improves the myocardial cell survival and inhibits the apoptosis by increasing the resistance of the cells to oxidative stress and exces-sive endoplasmic reticulum stress response, which is related with the activation of Akt phosphorylation in H/R-injured my-cardial cells.
