To observe the clinical efficacy of Huazhuo Jiedu formula in treating chronic erosive gastritis (CEG) patients with syndrome of accumulation of turbidity and toxicity, explore its mechanism by observing the changes in expression levels of hypoxia inducible factor (HIF-1α), vascular endothelial growth factor (VEGF) in serum and gastric mucosa tissues after treatment, and provide theoretical basis for the clinical application of Huazhuo Jiedu formula in treating chronic erosive gastritis. All 70 patient of CEG were randomly divided into control group and treatment group, 35 cases in each group. The patients in control group received Alatan Wuwei Wan, bid, 1 bag/time; while the patients in treatment group were given with Huazhuo Jiedu formula, 1 dose/day. The course of the treatment was 6 months in both groups. The changes in clinical symptoms, gastroscopic signs, pathology and the expression levels of HIF-1α, VEGF, and phosphatase and tensin homolog deleted on chromosome ten (PTEN) in serum and gastric mucosa tissues were observed in both groups. The results showed that treatment group was better than control group in clinical efficacy, gastroscopic efficacy and pathological effect after treatment (<0.05); the levels of HIF-1α and VEGF in serum of treatment group were lower than those in the control group after treatment (<0.05), while the level of PTEN in serum of treatment group was higher than that in the control group after treatment (<0.05); the levels of HIF-1α and VEGF in gastric mucosa tissues in the treatment group were lower than those in the control group after treatment, while the level of PTEN in gastric mucosa tissues in treatment group was higher than that in the control group after treatment (<0.05), with statistically significant differences between these two groups (<0.05). Huazhuo Jiedu formula can improve the clinical symptoms, gastroscopic signs and pathological conditions in CEG patients with syndrome of accumulation of turbidity and toxicity, and the mechanism may be associated with decreasing the expression level of HIF-1α, VEGF and increasing the expression level of PTEN.

AIM: To investigate the visual recovery and complications in patients with traumatic cataract treated by intraocular lens Ⅰ phase implantation and Ⅱ phase implantation.?METHODS: Totally 86 patients with traumatic cataract (86 eyes) treated in our hospital from January 2014 to December 2016 were enrolled in the retrospective study, and they were divided into the control group ( treated by intraocular lens Ⅰ phase implantation, 46 eyes) and the observation group ( treated by intraocular lens Ⅱ phase implantation, 40 eyes). The general situation of surgery, the visual recovery at 6mo after operation and the incidence rate of complications in two groups were observed.?RESULTS: There were no significant differences in surgical time, intraoperative blood loss and hospitalization time between the two groups (P>0. 05). There was no significant difference in the excellent and good rate of visual acuity between the two groups before operation between the twogroups (P>0. 05). At 6mo after operation, the excellent and good rates of visual acuity in two groups obviously increased ( P<0. 05 ), while there was no significant difference in the excellent and good rates of visual acuity at 6mo after operation between the two groups ( P > 0. 05 ). There was no significant difference between the two groups in the incidence rates of posterior capsule rupture and vitreous body prolapse (P>0. 05). The incidence rates of corneal edema, iridocyclitis and posterior capsular opacification in the observation group after operation were significantly lower than those in control group (P<0. 05).?CONCLUSION:The effects of IOLⅠphase implantation and Ⅱ phase implantation are similar in patients with traumatic cataract, in terms of the general situation and improvement of visual recovery. However, the incidence of complications after Ⅱ phase implantation is relatively lower.

Objective:To evaluate the effects of mind-body exercise on breast cancer patients using a Meta-analysis.Methods:Randomized controlled trials (RCTs) on the effects of mind-body exercises on breast cancer patients were systematically searched in PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, WanFang data, VIP, and China Biology Medicine disc, with a search period from database inception to November 30, 2023. The references of the included studies were also reviewed. After two reviewers independently screened the literature, extracted information, and evaluated the quality of the included studies, a Meta-analysis was performed using RevMan 5.3 software.Results:A total of 23 RCTs involving 1 730 breast cancer patients were included. The Meta-analysis showed that, compared to conventional care, mind-body exercise significantly reduced anxiety in breast cancer patients [ SMD=-0.46, 95% CI (-0.71, -0.21), P<0.01], as well as in those undergoing chemotherapy [ SMD=-0.30, 95% CI (-0.54, -0.07), P=0.01]. Mind-body exercise also alleviated depression in breast cancer patients. Subgroup analysis found that the Baduanjin group [ SMD=-1.13, 95% CI (-1.63, -0.64), P<0.01] was more effective in alleviating depression than the yoga group [ SMD=-0.24, 95% CI (-0.41, -0.07), P<0.01]. However, there was no statistically significant effect of mind-body exercise on improving the quality of sleep in breast cancer patients [ SMD=-0.41, 95% CI (-0.89, 0.06), P=0.09]. In terms of the effect of mind-body exercise on fatigue levels in breast cancer patients, subgroup analysis showed that Baduanjin [ SMD=-0.91, 95% CI (-1.26, -0.55), P<0.01] and Tai Chi [ SMD=-0.57, 95% CI (-0.92, -0.21), P<0.01] significantly reduced fatigue levels, while yoga [ SMD=-0.43, 95% CI (-0.98, 0.12), P=0.13] did not show a statistically significant effect on reducing fatigue levels in breast cancer patients. Conclusions:Mind-body exercises can reduce anxiety and depression and alleviate the level of fatigue in breast cancer patients. However, the effects of different exercise modalities on improving sleep quality in breast cancer patients vary.

The theory of medicinal properties of traditional Chinese medicine (TCM) is one of the core theories of TCM, which is an important basis for guiding the clinical application of TCM and the key supporting point for the modernization of TCM. How to study the modernization of TCM under the guidance of traditional Chinese medicine theory has become a great challenge for modern researchers. Currently, the researches in TCM mainly focus on chemical studies such as on active ingredients and effective components, lacking the guidance of traditional Chinese medicine theory, and losing the inherent characteristics of TCM. Therefore, the combination of the theory of TCM and the modernization of TCM and the establishment of research mode that is in line with the characteristics of modernization of traditional Chinese medicine under guidance by the theory of medicinal properties of TCM shall be the top priority in modern Chinese medicine research. The property and flavor of TCM are closely related to its chemical compositions, and also have certain regularity. The researches on the chemical components of TCM, systematic design of property and flavor, as well as the separation and combination of TCM property and flavor are beneficial to the overall analysis of the characteristics of TCM, showing great significance to inherit and carry forward TCM. The pharmacological effects about separation and combination methods based on TCM property and flavor were reviewed in this study, providing theoretical reference for the development of new drugs and the application of TCM.

BACKGROUNDPathophysiological processes, such as malignancy, can lead to the formation of stiffer tissue in lung cancers. Endobronchial ultrasound (EBUS) elastography is a novel technique for measuring tissue stiffness during EBUS-guided transbronchial needle aspiration (EBUS-TBNA). The current study was conducted to investigate the diagnostic value of EBUS elastography for mediastinal and hilar lymph node metastasis in lung cancers.

METHODSFrom January 2014 to January 2015, 40 patients suspected of lung cancer were enrolled, and a total of 68 lymph nodes were evaluated by EBUS-TBNA. EBUS-guided elastography of lymph nodes was performed prior to EBUS-TBNA. Standard EBUS characteristics were also described. Pathological determination of malignant or benign lymph nodes was used as the gold standard for this study. If EBUS-TBNA did not result in a formal pathological diagnosis of malignancy, patients were referred for a surgical procedure. Comparisons of elastography and standard EBUS characteristics were made between benign and malignant lymph nodes.

RESULTSElastography grading scores and strain ratios showed significant differences between benign and malignant lymph nodes (P = 0.000). The elastography strain ratio was more sensitive and specific for determining malignant lymph nodes than elastography grading score or standard EBUS criteria. The receiver operating characteristic curve for the elastography strain ratio showed an area under the curve of 0.933. The best cut-off point of the strain ratio for differentiating malignant from benign lymph nodes was 32.07. The elastography strain ratio had a sensitivity of 88.1%, the specificity of 80.8%, positive predictive value of 88.1%, and negative predictive value of 80.8% for distinguishing malignant from benign nodes. The overall accuracy of elastography strain ratio was 85.3%. The strain ratio of malignant and benign lymph nodes positively correlated with the elastography grading score (r = 0.561, P = 0.000).

CONCLUSIONSEBUS elastography can be effectively used to predict mediastinal and hilar lymph node metastases in lung cancer. This noninvasive technique may thus complement standard EBUS and help guide EBUS-TBNA procedures.

Objective:To analyze the long-term efficacy and safety of re-irradiation for recurrent glioma.Methods:The data of 52 patients with recurrent gliomas were collected from 2009 to 2019. The median planned targetvolume (PTV) was 73.5 cm 3(49.9-102.7 cm 3) and the median dose was 45.0 Gy (43.0-48.8 Gy). Kaplan-Meier method was used for survival assessment, log-rank test for difference assessment, and Cox’s regression model for multivariate prognostic analysis. Results:The median follow-up time was 32.6 months. The median overall survival (OS) and progression-free survival (PFS) time were 16.1 months (95% CI, 4.1-28.1) and 8.0 months (95% CI, 4.0-12.0). The 1-, 2-and 3-year survival rates were 67%, 43% and 29%, respectively. The 6-month, 1-year and 2-year PFS rates were 67%, 40%, 26%, respectively. Multivariate analysis showed that KPS score and recurrence time significantly affected the OS ( P=0.012, P=0.001). KPS score and time interval between two radiotherapies significantly impacted the PFS ( P=0.003, P=0.018). Stratified analysis showed that KPS score was the independent prognostic factor of OS and PFS in patients with WHO grade Ⅱ initial pathology and reoperation after recurrence ( P<0.001, P=0.012); clinical manifestation was the independent prognostic factor of OS and PFS in patients with WHO grade Ⅲ and Ⅳ initial pathology ( P=0.006, P=0.044). The overall incidence of adverse reactions was 30.8%. Grade 1 adverse reactions accounted for 25.0%, and 5.8% for grade 2. Conclusions:Re-irradiation for recurrent glioma yields good long-term clinical efficacy and tolerable adverse reactions.
