AIM: To investigate the effects of ginsenoside Rg1 injection combined with inosine tablets and vitamin B1 on serum brain-derived neurotrophic factor(BDNF), pituitary adenylate cyclase activating polypeptide(PACAP)and clinical efficacy in primary retinitis pigmentosa.METHODS: A total of 50 patients(100 eyes)with primary retinitis pigmentosa who admitted to the Department of Ophthalmology, the Second Affiliated Hospital of Hebei North University from August 2019 to March 2022 were selected as the research object. They were divided into the study group and the control group according to random number table, with 50 eyes in each group. Patients in the control group were treated with inosine tablets and vitamin B1, while patients in the study group were treated with ginsenoside Rg1 injection on the basis of the control group. The expression of BDNF and PACAP in serum, electroretinogram and spectral-domain optical coherence tomography(SD-OCT)were compared before and after treatment, and the retinal thickness(RT), mean deviation(MD), clinical efficacy and safety indexes were compared between the two groups.RESULTS: There were no differences in the MD of the two groups before treatment(t=1.670, P=0.098), while the MD of the study group was significantly lower than that of the control group after treatment(t=3.628, P<0.01). Before treatment, RT with a diameter of 1mm at the circle of macular fovea was compared between the two groups(t=0.108, P=0.914), it was significantly higher than that in the control group after treatment(t=6.125, P<0.01). Before treatment, there was no significant difference in the results of dark adaptation of electroretinogram between the two groups(all P>0.05). After treatment, the results of dark adaptation in the study group were significantly better than those in the control group(all P<0.01). Before treatment, there was no significant difference in the results of electroretinogram adaptation between the two groups(all P>0.05). After treatment, the results of electroretinogram adaptation in the study group were significantly better than those in the control group(all P<0.01). There was no significant difference in BDNF and PACAP between the two groups before treatment(all P>0.05). BDNF and PACAP in the study group were higher than those of the control group after treatment(all P<0.01). After treatment, no adverse reactions were observed in both groups.CONCLUSION: The treatment of patients with primary retinitis pigmentosa with ginsenoside will improve the retinal function and promote the prognosis of the disease by regulating the expression of BDNF and PACAP, and it is highly safe.

This study aims to investigate the effect of Astragali Radix-Curcumae Rhizoma(AC) combination on the proliferation, migration, and invasion of colon cancer HT-29 cells based on epithelial-mesenchymal transition(EMT). HT-29 cells were respectively treated with 0, 3, 6 and 12 g·kg~(-1) AC-containing serum for 48 h. The survival and growth of cells were measured by thiazole blue(MTT) colorimetry, and the proliferation, migration, and invasion of cells were detected by 5-ethynyl-2'-deoxyuridine(EdU) test and Transwell assay. Cell apoptosis was examined by flow cytometry. The BALB/c nude mouse model of subcutaneous colon cancer xenograft was established, and then model mice were classified into blank control group, 6 g·kg~(-1) AC group, and 12 g·kg~(-1) AC group. The tumor weight and volume of mice were recorded, and the histopathological morphology of the tumor was observed based on hematoxylin-eosin(HE) staining. The expression of apoptosis-associated proteins B-cell lymphoma-2-associated X protein(Bax), cysteine-aspartic acid protease-3(caspase-3), and cleaved caspase-3, and EMT-associated proteins E-cadherin, MMP9, MMP2 and vimentin in HT-29 cells and mouse tumor tissues after the treatment of AC was determined by Western blot. The results showed that cell survival rate and the number of cells at proliferation stage decreased compared with those in the blank control group. The number of migrating and invading cells reduced and the number of apoptotic cells increased in the administration groups compared with those in the blank control group. As for the in vivo experiment, compared with the blank control group, the administration groups had small tumors with low mass and shrinkage of cells and karyopycnosis in the tumor tissue, indicating that the AC combination may improve EMT. In addition, the expression of Bcl2 and E-cadherin increased and the expression of Bax, caspase-3, cleaved caspase-3, MMP9, MMP2, and vimentin decreased in HT-29 cells and tumor tissues in each administration group. In summary, the AC combination can significantly inhibit the proliferation, invasion, migration, and EMT of HT-29 cells in vivo and in vitro and promote the apoptosis of colon cancer cells.

Objective To make a systematic review of therapeutic effect of electroacupuncture(EA) for idiopathic facial palsy at acute stage. Methods With reference to the included criteria and excluded criteria, clinical controlled trials of EA for idiopathic facial palsy at acute stage were screened from the databases of CBM, CNKI, Wanfang, VIP by computer retrieval and from the primary domestic academic journals of acupuncture by manual retrieval. Systematic review was performed following the Cochrane Reviewers' Handbook, and RevMan 5.3 was used for Meta-analysis. Results Sixteen clinical trials were included. The Meta-analysis results showed that the cure rate evaluated with 3 kinds of therapeutic effect criteria in the observation group was superior to that of the control group, the difference being significant (P<0.05 or P<0.01); the effects on improving days for cure, cure case number within one month, blink reflex, and case number with complications in the observation group were also superior to that of the control group, the difference being significant (P < 0.01). Conclusion EA exerts certain therapeutic effect for idiopathic facial palsy at acute stage. But for the quantity and quality of the included trials are not satisfactory, the conclusion still needs more high-quality, large-size and long-term follow-up trials to verify.

Objective: To explore the risk predictive value of lipoprotein-associated phospholipase A2 (Lp-PLA2) on acute coronary syndrome(ACS) and to study the relationship between Lp-PLA2 and the severity of coronary stenosis in ACS patients. Methods:A total of 155 ACS patients admitted in our hospital were enrolled. The patient were divided into 2 groups:AMI (acute myocardial infarction) group, n=49 and UA (unstable angina)group, n=106; in addition, there was a Control group, n=44 subjects with normal coronary angiography (CAG).Blood levels of Lp-PLA2 were examined, CAG was conducted and GRACE score, SYNTAX score,Gensini score were calculated. Based on Grace score, ACS patients were divided into 3 subgroups: Low risk subgroup, Grace score≤108, Mid risk subgroup,Grace score 109-140 and High risk subgroup,Grace score≥140.The above parameters were comparedamong different groups. Results: Compared with UA group and Control group, AMI group had increased blood level of Lp-PLA2, P<0.05. Compared with Low risk subgroup, High risk subgroup had much higher Lp-PLA2, P<0.05. Correlation analysis showed that Lp-PLA2 level was positively related to Gracescore (r=0.301, P<0.001). By SYNTAX score and Gensini score evaluation,Lp-PLA2 levels were similar among different subgroups. Conclusion:Blood level of Lp-PLA2 had certain risk predictive value in ACS patients; while it was not related to the severity of coronary stenosis.

Arisaema heterophyllum Blume is one of the three medicinal plants known as traditional Chinese medicine Rhizoma Arisaematis (RA). RA has been popularly used to treat patients with convulsions, inflammation, and cancer for a long time. However, the underlying mechanisms for RA effects are still unclear. The present study was designed to determine the cytotoxicity of agglutinin isolated from Arisema heterophyllum Blume (AHA) and explore the possible mechanisms in human non-small-cell lung cancer A549 cells. AHA with purity up to 95% was isolated and purified from Arisaema heterophyllum Blume using hydrophobic interaction chromatography. AHA dose-dependently inhibited the proliferation of A549 cells and induced G phase cell cycle arrest. AHA induced apoptosis by up-regulating pro-apoptotic Bax, decreasing anti-apoptotic Bcl-2, and activating caspase-9 and caspase-3. In A549 cells treated with AHA, the PI3K/Akt pathway was inhibited. Furthermore, AHA induced increase in the levels of ER stress markers such as phosphorylated eukaryotic initiation factor 2α (p-eIF2α), C/EBP-homologous protein (CHOP), inositol-requiring enzyme 1α (IRE1α), and phosphorylated c-Jun NH-terminal kinase (p-JNK). AHA also induced autophagy in A549 cells. Staining of acidic vesicular organelles (AVOs) and increase in the levels of LC3II and ATG7 were observed in AHA-treated cells. These findings suggested that AHA might be one of the active components with anti-cancer effects in Arisaema heterophyllum Blume. In conclusion, cytotoxicity of AHA on cancer cells might be related to its effects on apoptosis and autophagy through inhibition of PI3K/Akt pathway and induction of ER stress.

BACKGROUNDNontraumatic osteonecrosis of the femoral head (NONFH) is a debilitating disease that represents a significant financial burden for both individuals and healthcare systems. Despite its significance, however, its prevalence in the Chinese general population remains unknown. This study aimed to investigate the prevalence of NONFH and its associated risk factors in the Chinese population.

METHODSA nationally representative survey of 30,030 respondents was undertaken from June 2012 to August 2013. All participants underwent a questionnaire investigation, physical examination of hip, and bilateral hip joint X-ray and/or magnetic resonance imaging examination. Blood samples were taken after overnight fasting to test serum total cholesterol, triglyceride, and high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels. We then used multivariate logistic regression analysis to investigate the associations between various metabolic, demographic, and lifestyle-related variables and NONFH.

RESULTSNONFH was diagnosed in 218 subjects (0.725%) and the estimated NONFH cases were 8.12 million among Chinese people aged 15 years and over. The prevalence of NONFH was significantly higher in males than in females (1.02% vs. 0.51%, χ2 = 24.997, P < 0.001). Among NONFH patients, North residents were subjected to higher prevalence of NONFH than that of South residents (0.85% vs. 0.61%, χ 2 = 5.847, P = 0.016). Our multivariate regression analysis showed that high blood levels of triglycerides, total cholesterol, LDL-cholesterol, and non-HDL-cholesterol, male, urban residence, family history of osteonecrosis of the femoral head, heavy smoking, alcohol abuse and glucocorticoid intake, overweight, and obesity were all significantly associated with an increased risk of NONFH.

CONCLUSIONSOur findings highlight that NONFH is a significant public health challenge in China and underscore the need for policy measures on the national level. Furthermore, NONFH shares a number of risk factors with atherosclerosis.

Introduction:Right-sided colon cancer (RSCC) and left-sided colorectal cancer (LSCRC) differ with respect to their biology and genomic patterns. This study aimed to examine whether the primary tumor location is associated with the response to cetuximab in patients with metastatic colorectal cancer (mCRC). Methods:Patients with mCRC treated with cetuximab and standard chemotherapy as first-or second-line treatments were compared with randomly chosen patients who were treated with chemotherapy alone between 2005 and 2013. The main outcome measures were the overal response rate (ORR), progression-free survival (PFS), and overal survival (OS). The differences in the outcome were analyzed by using the chi-squared test, Student’s t test, and Kaplan-Meier method. Results:The treatment results of 206 patients with mCRC treated with cetuximab and standard chemotherapy as first-or second-line treatments were compared with those of 210 patients who were treated with chemotherapy alone. As a first-line treatment, cetuximab with chemotherapy was associated with a significantly higher ORR (49.4%vs. 28.6%, P=0.005) as well as longer PFS (9.1 vs. 6.2 months, P=0.002) and OS (28.9 vs. 20.1 months, P=0.036) than chemotherapy alone in patients with LSCRC. However, cetuximab neither improved the ORR (36.4%vs. 26.2%, P=0.349) nor prolonged PFS (5.6 vs. 5.7 months, P=0.904) or OS (25.1 vs. 19.8 months, P=0.553) in patients with RSCC. As a second-line treatment, cetuximab exhibited a tendency to improve the ORR (23.5%vs. 10.2%, P=0.087) and prolong PFS (4.9 vs. 3.5 months, P=0.064), and it significantly prolonged OS (17.1 vs. 12.4 months, P=0.047) compared with chemotherapy alone in the patients with LSCRC. In contrast, as a second-line treatment, cetuximab neither improved the ORR (7.1%vs. 11.4%, P=0.698) nor prolonged PFS (3.3 vs. 4.2 months, P=0.761) or OS (13.4 vs. 13.0 months, P=0.652) in patients with RSCC. Conclusions:The addition of cetuximab to chemotherapy in both first-and second-line treatments of mCRC may only benefit patients with primary LSCRC.
