ABSTRACT
OBJECTIVE To explore the effects of ADRB1 Arg389Gly polymorphisms on the efficacy of bisoprolol， thus providing some information for individualized drug therapy. METHODS A systematic search was conducted in PubMed， Embase， Cochrane Library， CBM， CNKI， and Wanfang Data to retrieve and find out all relevant literature about bisoprolol and ADRB1 Arg389Gly polymorphism from the inception to May 2023. The retrieved literature was screened and selected according to the inclusive and exclusive criteria， thereafter quality assessment was conducted. RevMan 5.4 software was utilized to perform the meta- analysis for the outcome index. RESULTS Overall 7 literature with 1 339 cases were included. Among them， 4 studies provided the changes in systolic blood pressure （SBP）， diastolic blood pressure （DBP） （ΔSBP and ΔDBP）； 4 involving the change （ΔLVEF） of left ventricular ejection fraction （LVEF）. Results of the study showed that there was no statistical significance in the improvement of blood pressure between wild-type group （AA） and mutation group （AG+GG） of ADRB1 Arg389Gly treated with bisoprolol {ΔSBP [SMD＝0.17，95%CI （－0.97，1.31）， P＝0.77]， ΔDBP [SMD＝－0.01，95%CI （－0.65，0.62）， P＝0.97]}； there was no statistical significance in the improvement of ΔLVEF [SMD＝－0.61， 95%CI （－2.74，1.53）， P＝0.58] between 2 groups. CONCLUSIONS ADRB1 Arg389Gly gene polymorphism has no significant influence on the improvement of SBP， DBP， and LVEF in cardiovascular patients who use bisoprolol.
ABSTRACT
In recent years， clinical studies on targeted therapy and immunotherapy for advanced hepatocellular carcinoma used alone or in combination have provided abundant evidence on efficacy and safety for the selection of first-line therapies. However， no consensus has been reached on the selection of second-line therapies in various clinical guidelines for hepatocellular carcinoma， which is caused by the fact that existing evidence is limited to the options after failure of sorafenib and that there is still a lack of high-level evidence for new first-line therapies such as second-line therapies after resistance to targeted therapy and immunotherapy for hepatocellular carcinoma. This article reviews the results of current clinical trials and summarizes the studies on second-line therapies for hepatocellular carcinoma after resistance to first-line targeted therapy and immunotherapy for hepatocellular carcinoma based on the different mechanisms of action of drugs， as well as the research advances in recent years. For hepatocellular carcinoma patients with resistance to first-line targeted therapy and immunotherapy， targeted combination therapy and dual-immune therapy are expected to improve treatment outcome and survival， and more prospective clinical studies are needed in the future to provide effective and safe treatment regimens for hepatocellular carcinoma patients with resistance to targeted therapy and immunotherapy.
ABSTRACT
Traditional Chinese Medicine (TCM) non-drug therapy for gastroesophageal reflux mainly includes appropriate TCM techniques, such as conventional acupuncture, moxibustion, fire needle, etc. Emotional therapy, such as regulating emotion, transforming the patient's spirit and change the state of qi, the five-element music therapy, etc; exercise therapy, such as Baduanjin and Zhanzhuang, can be used alone, or in combination, or in combination with oral administration of Chinese materia medica. By reducing the probability of esophageal sphincter relaxation, inhibiting gastric acid secretion, improving esophageal motility disorder, reducing visceral hypersensitivity, immune regulation and other effects, it can alleviate the symptoms of acid reflux, heartburn and pharyngeal discomfort, and help to improve the patients' anxiety, depression and other negative emotions. It has the characteristics of simplicity and fewer adverse reactions, at the same time, according to the patient's condition and compliance to choose the appropriate therapy. The mechanism of TCM non-drug therapy in the treatment of this disease needs to be further explored, so as to better guide clinical popularization and application.
ABSTRACT
Objective:To investigate the modified application of orbicularis oculi muscle-levator aponeurosis composite tissue flap fixation technique (modified Park method) in double-eyelid surgery.Methods:From June 2019 to March 2021, 823 patients included 92 males and 731 females, aged from 18 to 45 years with mean (31.4±7.9) years, in which 142 patients with slightly ptosis were selected to receive the treatment in the Department of Plastic Surgery of the Affiliated Hospital of Nangjing University of TCM. The symmetry of bilateral double eyelids after operation was evaluated by the third party. The marginal reflex distance (MRD1) was measured before and 6 months after operation, and the difference between preoperative and postoperative MRD1 (ΔMRD1) was calculated. And the postoperative complications were counted. The patients were followed up from 6 to 12 months after surgery to evaluate the long-term results.Results:The patients were followed up for 4-22 months (mean 10 months) after operation. And the incisions of all the 823 cases had primary healling. Most patients had smooth upper eyelid crease, upturned lashes and dynamic fold. The skin tended to spread evenly without dimple. The symmetry evaluation by the third party showed that there were 764 patients with symmetry and basic symmetry after operation, the symmetry rate was 92.8%; 59 patients with asymmetry, the asymmetry rate was 7.2%. The data of MRD1 increased significantly 6 months after operation, from (3.25±0.72) mm to (3.64±0.61) mm, and the ΔMRD1 was (0.38±0.76) mm ( t=-20.41, P<0.05). The difference between the two groups was statistically significant. The double eyelid line became shallow in 8 cases and disappeared completely in 3 cases. The double eyelid curve of the patients was natural and smooth after the operation. And there was no obvious sunken scar and pretarsal fullness. Conclusions:The " modified Park technique" blepharoplasty can obtain a more firm, symmetrical and natural appearance. And the mild ptosis could be corrected by this method. The anatomical structure can be identified clearly, and the surgical results are highly repeatable. It is worth promoting.
ABSTRACT
Objective:To establish a clinical diagnostic scoring model for preoperative predicting hepatocellular carcinoma (HCC) microvascular invasion (MVI) based on gadolinium-ethoxybenzyl-diethylenetriamine pentacetic acid (Gd-EOB-DTPA) enhanced MRI, and verify its effectiveness.Methods:From January 2014 to December 2020, a total of 251 cases with pathologically confirmed HCC from Tianjin First Central Hospital and Jilin University First Hospital were retrospectively collected to serve as the training set, while 57 HCC patients from Tianjin Medical University Cancer Hospital were recruited as an independent external validation set. The HCC patients were divided into MVI positive and MVI negative groups according to the pathological results. The tumor maximum diameters and apparent diffusion coefficient (ADC) values were measured. On the Gd-EOB-DTPA MRI images, tumor morphology, peritumoral enhancement, peritumoral low intensity (PTLI), capsule, intratumoral artery, intratumoral fat, intratumoral hemorrhage, and intratumoral necrosis were observed. Univariate analysis was performed using the χ 2 test or the independent sample t-test. The independent risk factors associated with MVI were obtained in the training set using a multivariate logistic analysis. Points were assigned to each factor according to the weight value to establish a preoperative score model for predicting MVI. The receiver operating characteristic (ROC) curve was used to determine the score threshold and to verify the efficacy of this scoring model in predicting MVI in the independent external validation set. Results:The training set obtained 98 patients in the MVI positive group and 153 patients in the MVI negative group, while the external validation set obtained 16 patients in the MVI positive group and 41 patients in the MVI negative group. According to logistic analysis, tumor maximum diameter>3.66 cm (OR 3.654, 95%CI 1.902-7.018), hepatobiliary PTLI (OR 9.235, 95%CI 4.833-16.896) and incomplete capsule (OR 6.266, 95%CI 1.993-9.345) were independent risk factors for MVI in HCC, which were assigned scores of 3, 4 and 2, respectively. The total score ranged from 0 to 9. In the external validation set, ROC curve analysis showed that the area under the curve of the scoring model was 0.918 (95%CI 0.815-0.974, P=0.001). When the score>4 was used as the threshold, the accuracy, sensitivity, and specificity of the model in predicting MVI were 84.2%, 81.3%, and 85.4%, respectively. Conclusions:A scoring model based on Gd-EOB-DTPA-enhanced MRI provided a convenient and reliable way to predict MVI preoperatively.
ABSTRACT
Objective:To evaluate the curative effect of autogenous cartilage transplantation in the correction of nasal soft-tissue triangle deformities aided by 3D technology.Methods:From January 2016 to January 2018, 32 patients with nasal soft-tissue triangle deformities were collected, with 7 males and 25 females, aged from 18 to 32 years (mean 28.5±6.8 years). A part of the costal cartilage/nasal septum cartilage or auricular cartilage was cut as repair material, which was carved into strips, and used as nasal alar rim grafts to reconstruct the dome shape and correct the nasal soft triangle deformities. The costal cartilage or nasal septum cartilage was used to strengthen the support of the columella nasi and augmentation rhinoplasty was performed with prosthesis, and the fascia was placed on nose tip to relieve tension. The surgical results were evaluated by comparing the pre- and post-operative images; statistical analysis was conducted to compare the difference of alar cartilage angle along inside and outside implants before and after the fornix reconstruction, and the difference of maximum distance from the nostrils long shaft to the nose flange between pre- and post-operation, and so the effect of nasal soft triangular deformity correction was evaluated.Results:The alar cartilage angle of the 32 patients was (51.5±10.9)° before surgery, and decreased to (37.2±5.9)° after surgery; the difference was statistically significant ( P<0.05). The maximum distance from the nostrils long shaft to the nose flange was (3.3±0.6) mm before surgery, and it reduced to (1.9±0.7) mm after surgery; the difference was statistically significant ( P<0.05). The patients were followed up for 6 to 18 months, and the result showed that the curative effect was significant, with good appearance and natural feeling, and there were no serious complications, and the satisfactory rate was 87.5%. Conclusions:Autogenous cartilage is used to repair nasal soft-tissue triangle deformities aided by 3D technology; the nasal morphology is improved delicately, and the postoperative satisfaction of curative effect is high, which is an ideal surgical method.
ABSTRACT
Objective:To investigate the efficacy and safety of partial resection or enhanced suture of retro-orbicularis oculi fat (ROOF) through double eyelid or subeyebrow incision to correct upper eyelid swelling and depression.Methods:From May 2017 to June 2018, 166 beauty seekers underwent the operation. Among them, 81 cases were corrected by double eyelid incision, 33 cases were corrected by double eyelid incision, 30 cases were corrected by subeyebrow incision and 22 cases were corrected by subeyelid incision.Results:The swelling and depression of the upper eyelid were improved and the patients were satisfied. Two of the patients developed hematoma after operation and all healed after debridement.Conclusions:Preorbital septum fat combined with ROOF partial excision or enhanced suture can effectively improve the upper eyelid swelling or depression, with high satisfaction, safety and less trauma, which can be an important supplement for upper eyelid plastic surgery.
ABSTRACT
Objective:To investigate the effects of anemoside B4 on apoptosis of retinal cells in diabetic rats.Methods:Sixty Sprague-Dawley rats were randomized into three groups: the normal control(control), diabetic rats(DM)and diabetic rats treated with Anemoside B4(B4)groups(n=20, each group). Rats in the DM and B4 groups were rendered diabetic with an intraperitoneal injection of streptozotocin(STZ, 60 mg/kg). After 3 days of successful modeling, rats in the B4 group were intraperitoneally injected with anemoside B4(5 mg/kg), twice/day, for 8 weeks, while rats in the control and DM groups were injected with an equivalent volume of normal saline.After 8 weeks of anemoside B4 and normal saline injection, rats were sacrificed and retinas were harvested for examination.Paraffin sections of retina were stained with the hematoxylin-eosin(H-E)method for morphological evaluation.Protein levels of Bax and Bcl-2 were detected by using Western blot.The expression of caspase-3 mRNA was detected with quantitative PCR.Results:H-E staining results showed the control group had intact retinal structure and clear morphological features, whereas disordered retinal structure, thinner layers, and sparse and disorganized cells were seen in the DM group.However, retinal structure and morphology were improved after treatment with anemoside B4.Compared with the control group, the protein expression of Bcl-2 was lower( t=57.81, P<0.01), the protein expression of Bax was higher( t=10.47, P<0.01), and the Bcl-2/Bax ratio was lower( t=23.98, P<0.01)in the DM group.Compared with the DM group, the protein expression of Bcl-2 was higher( t=41.07, P<0.01), the protein expression of Bax was lower( t=6.811, P<0.01), and the Bcl-2/Bax ratio was higher( t=14.70, P<0.01)in the B4 group.Caspase-3 mRNA expression was higher in the DM group than in the control group( t=7.916, P<0.01), but was lower in the B4 group compared with the DM group( t=6.221, P<0.01). Conclusions:Anemoside B4 can inhibit the apoptosis of retinal cells by up-regulating Bcl-2 expression and down-regulating Bax and caspase-3 expression in diabetic rats.
ABSTRACT
Base excision repair (BER) is an important pathway for DNA oxidative damage repair,and mutations in this pathway cause gene instability and increase cancer risk.A large number of studies have shown that abnormal expression of key proteins in the BER pathway in a variety of tumors,such as DNA glycosylase,apurinic/apyrimidinic endonuclease 1,DNA polymerase and so on.Single nucleotide polymorphisms of these proteins affect the repair activity of tumor cells,and are expected to be important indicators for the diagnosis,treatment and evaluation of prognosis.
