Multi-omics data-based analysis characterizes molecular alterations of the vesicle genes in human colorectal cancer.

The role of vesicular genes in the development of colorectal cancer (CRC) is crucial. Analyzing alterations in these genes at multi-omics can aid in understanding the molecular pathways behind colorectal carcinogenesis and identifying potential treatment targets. However, studies on the overall alteration of vesicular genes in CRC are still lacking. In this study, we aimed to investigate the relationship between vesicle genetic alterations and CRC progression. To achieve this, we analyzed molecular alterations in CRC vesicle genes at eight levels, including mRNA, protein, and epigenetic levels. Additionally, we examined CRC overall survival-related genes that were obtained from a public database. Our analysis of chromatin structural variants, DNA methylation, chromatin accessibility, and proteins (including phosphorylation, ubiquitination, and malonylation), along with RNA-seq data from the TCGA database, revealed multiple levels of alterations in CRC vesicle genes in the collected tissue samples. We progressively examined the alterations of vesicle genes in mRNA and protein levels in CRC and discovered the hub genes. Further investigation identified the probable essential transcription factors. This study contributes to a thorough knowledge of the connection between vesicle gene alterations at multiple levels and the development of CRC and offers a theoretical framework for the identification of novel treatment targets.

A meta-analysis of the efficacy and safety of the traditional Chinese medicine formula Kaixinsan decoction for depression.

BACKGROUND: Kaixinsan (KXS) decoction is a traditional Chinese herbal formulation commonly used to treat depression. This study aimed to evaluate the efficacy and safety of KXS, which is widely used, alone and in combination with other therapies, for the treatment of depression. The main objective was to assess the efficacy and safety of KXS in the treatment of depression as a single agent or in combination with other methods. METHODS: Randomized controlled trials of KXS in the treatment of depression were systematically searched from several Chinese and English databases with no language restriction. Patients in these studies met the relevant diagnostic criteria for depression. Data on HAMD, SDS, practical situations, and occurrence of side effects in the studies were extracted. Finally, the methodological quality and risk of bias of the included studies were assessed using the Jadad scale and Cochrane bias evaluation tool. RESULTS: Twelve studies with 1034 patients were included after screening. The Jadad scale and Cochrane bias evaluation tool indicated that the quality of the studies ranged from fair to good, with 41.7% categorized as good and 58.3% as poor. Egger test and funnel plots showed that the publication bias remain low. CONCLUSION: The results showed that the frequency of side effects in the control group was higher than that in the treatment group, and there was a statistically significant difference. KXS was comparable or superior to antidepressants in treating depression and has fewer side effects. The data analysis showed that effectiveness and other indicators differed significantly by geographic area and dosage form, which has implications for future clinical work.

[Clinical observation on deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle for trigeminal neuralgia of wind and heat].

OBJECTIVE: To compare the clinical therapeutic effect between deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle and conventional acupuncture in patients with trigeminal neuralgia (TN) of wind and heat, and explore its mechanism. METHODS: A total of 60 patients with TN of wind and heat were randomized into an observation group (30 cases) and a control group (30 cases). In the observation group, deep needling with round sharp needle was applied at Xiaguan (ST 7), and tapping with plum-blossom needle was applied at Yangbai (GB 14), Quanliao (SI 18), Dicang (ST 4), Sibai (ST 2), etc. of affected side. In the control group, conventional acupuncture was applied at the same acupoints selected in the observation group. The treatment was given once a day, 5 times a week for 4 weeks in the both groups. Before and after treatment, the scores of short-form McGill pain questionnaire (SF-MPQ), TCM syndrome, patient global impression of change (PGIC) and comprehensive symptom were observed, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), vasoactive intestinal peptide (VIP) and ß-endorphin (ß-EP) were detected, and the adverse reaction was observed in the both groups. RESULTS: After treatment, the scores of PRI, PPI, VAS, TCM syndrome, PGIC and comprehensive symptom and the serum levels of IL-6, TNF-α and VIP were decreased compared before treatment in the both groups (P<0.05), and the variations of above indexes in the observation group were larger than those in the control group (P<0.05). After treatment, the serum levels of ß-EP were increased compared before treatment in the both groups (P<0.05), and the variation of that in the observation group was larger than the control group (P<0.05). No severe adverse reaction was observed in the both groups. CONCLUSION: Deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle can effectively treat the trigeminal neuralgia of wind and heat and relieve pain, its therapeutic effect is superior to conventional acupuncture. The mechanism may be related to the regulation of serum IL-6, TNF-α, VIP and ß-EP.

Islet transplantation ameliorates diabetes-induced testicular interstitial fibrosis and is associated with inhibition of TGF-ß1/Smad2 pathway in a rat model of type 1 diabetes.

Islet transplantation (IT) is considered the most effective endocrine replacement therapy for diabetes mellitus (DM). Studies have demonstrated that IT can repair testicular structural injury caused by inflammatory and oxidative stress in a diabetic rat model. However, highly effective exogenous antioxidant and anti-inflammatory drugs can achieve this effect. Testicular interstitial fibrosis caused by long-term hyperglycemia is however difficult to reverse or recover. Thus far, there are no effective drugs that prevent or relieve testicular interstitial fibrosis. Therefore, it is necessary to explore the potential benefit of IT on testicular interstitial fibrosis induced by DM and its underlying molecular mechanisms. In the present study, Wistar rats were used to establish a DM model by intraperitoneal injection of streptozotocin. The diabetic models then underwent IT or received insulin treatment after 12 weeks. IT was more effective than insulin treatment in ameliorating diabetic-induced testicular interstitial fibrosis, Leydig cells apoptosis, testosterone deficiency and poor sperm motility. IT and insulin treatment both significantly inhibited the upregulation of TGF-ß1 and phosphorylated Smad2 in DM, with IT being more effective than insulin. The present study's findings proved that IT effectively protects diabetic-induced testicular interstitial fibrosis probably by inhibiting the TGF-ß1/Smad2 signaling pathway, which offers hope in male patients with DM complicating with testicular interstitial fibrosis.

Effects of Exercise Intervention on Preventing Letrozole-Exposed Rats From Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is a prevalent endocrinological disorder in reproductive-age women and is often associated with a metabolic syndrome. To investigate whether exercise intervention promotes PCOS prevention, a rat model was used. Polycystic ovary syndrome was induced by letrozole administration, and animals presented with obesity, sex hormone disorder, no ovulation, large cystic follicles, and increasing fasting insulin (FINS) and leptin levels. The intervention was set at 3 different intensities of swimming exercise: low (0.5 h/d), moderate (1 h/d), and high (2 h/d), and compared with a PCOS model group (letrozole administration without exercise intervention) and a control group. The exercise intervention in the low-intensity group did not produce changes in obesity, testosterone, progesterone (P), and follicle-stimulating hormone (FSH) levels. Moderate-intensity exercise reduced body weight, retained ovulation, and P levels were increased but remained lower than those in the control group. The FSH levels were significantly higher, and FINS and leptin levels were lower than in the model group ( P < 0.05) but not in the control group. The high-intensity group demonstrated the greatest effect of PCOS prevention. Testosterone, luteinizing hormone, FINS, and leptin levels were significantly lower in the high-intensity group, and FSH and P levels were higher compared with the model group. These results suggest that high-intensity exercise intervention can effectively prevent PCOS development.

[Efficacy and safety of telbivudine in pregnant women to prevent perinatal transmission of hepatitis B virus].

OBJECTIVE: To evaluate the efficacy and safety of telbivudine use during the second and third trimester of pregnancy for reducing hepatitis B virus (HBV) transmission from highly viremic hepatitis B e antigen-positive (HBeAg+) mothers to their fetuses. METHODS: Pregnant women, between weeks 20 to 32 of gestation, who were HBeAg+ and had HBV DNA more than 1.0*10(7) copies/mL were enrolled in our study. The women were offered inclusion into one of two treatment arms, based upon their personal preference: telbivudine or no telbivudine. The patients in the telbivudine treatment arm were administered 600 mg/d telbivudine at least until postpartum week 4. All delivered infants in both treatment arms were administered hepatitis B immune globulin (HBIG; 200 IU) within 12 hours of delivery and recombinant HBV vaccine (20 mug) at 0, 1 and 6 months. The HBV perinatal transmission rate was determined by measuring HBsAg and HBV DNA in infants at postpartum week 28. RESULTS: A total of 220 pregnant women were enrolled in our study, 120 chose the telbivudine arm and 100 chose the control arm. All telbivudine treated subjects were registered in the Antiretroviral Pregnancy Registry. Telbivudine treatment was associated with a marked reduction in the mothers' serum HBV DNA, HBeAg and ALT levels before delivery. A striking decline of HBV DNA levels in treated mothers was observed at week 2 of treatment, which was followed by a gradual and steady decrease that continued until delivery. Thirty-seven (31%) of the telbivudine-treated mothers and none (0%) of the untreated controls had polymerase chain reaction-undetectable viremia at delivery. At week 28, 0% of the infants delivered from telbivudine-treated mothers were HBsAg+ or HBV DNA+, as compared to 8% HBsAg+ or HBV DNA+ in the untreated control arm (P = 0.002). No telbivudine discontinuations occurred from adverse events, and no congenital deformities were observed in the infants delivered to telbivudine-treated mothers. Eighty mothers discontinued telbivudine at week 4 postpartum, and there were no cases of severe hepatitis. There were no significant differences between the two treatment arms for postpartum hemorrhage, adverse events during pregnancy, cesarean section, gestational age, or infants' height/weight or Apgar scores. CONCLUSIONS: Telbivudine use during the second and third trimester of pregnancy in HBeAg+ highly viremic mothers can safely reduce perinatal HBV transmission rates. Telbivudine was well-tolerated by our patient group. Furthermore, no safety concerns were observed in either the telbivudine-treated mothers or their delivered infants in short term follow-up.
