Causal Relationships between Homocysteine and the Polycystic Ovary Syndrome: A Mendelian Randomization Analysis.

Background: Polycystic ovary syndrome (PCOS) is an endocrine disease attributed to multiple genetic variants and environmental factors. We aimed to find the causal association of homocysteine (Hcy) with PCOS. Methods: A two-sample Mendelian randomization (MR) analysis was performed. We selected 14 single-nucleotide polymorphisms (SNPs) as instrumental variables to predict the risk of PCOS from genome-wide association studies (GWAS). The summary statistics of PCOS were obtained from 3 large genome-wide association studies in the European population, involving 4,138 cases and 20,129 controls, 3,609 cases and 229,788 controls, 994 cases and 165,817 controls, separately. Results: The IVM analyses revealed that plasma Hcy levels were not causally associated with the risk of PCOS in the meta-analysis (combined effect = 1.032, 95% confidence interval (CI): 0.885-1.203, p=0.688). Conclusions: There was no sufficient evidence to support the causal association of the Hcy with the risk of PCOS.

Research hotspots and trends in postlaparoscopic shoulder pain from 2003 to 2023: A bibliometric analysis.

The incidence of postlaparoscopic shoulder pain has recently increased and has attracted increasing attention from clinical workers, but no study has performed bibliometric and visual analysis of the relevant literature. This study used bibliometric and visual analysis to conduct a comprehensive and systematic evaluation of postlaparoscopic shoulder pain to help researchers understand the latest global trends and hotspots and provide a reference for caregivers to carry out PLSP care interventions and research. Related studies on postlaparoscopic shoulder pain from 2003 to 2023 were retrieved from the Web of Science Core Collection. We analysed current research trends and hotspots in this field using VOSviewer and CiteSpace. A total of 2451 authors from 352 institutions in 50 countries published 464 studies related to postlaparoscopic shoulder pain. The United States was the country with the most publications and worked closely with other countries. Donmez Turgut was the researcher with the most published articles, while Bisgaard T had the most citations per article. The Journal of Surgical Endoscopy was cited most frequently, totalling 356 times. Through keyword significance analysis, we found that relieving postlaparoscopic shoulder pain in patients through integrated care interventions was an emerging research hotspot. This bibliometric and visual analysis provides a comprehensive review of studies related to postlaparoscopic shoulder pain. The current global research trend and hotspot is to alleviate postlaparoscopic shoulder pain through integrated care interventions, but the advantages of this approach are not outstanding. However, further research and global collaboration are still needed. Our findings can help researchers understand the current status of postlaparoscopic shoulder pain research and identify new directions for future research.

Emergency rescue of a patient with hemorrhagic shock caused by superior mesenteric artery rupture: A case report.

BACKGROUND: Superior mesenteric artery (SMA) injuries rarely occur during blunt abdominal injuries, with an incidence of < 1%. The clinical manifestations mainly include abdominal hemorrhage and peritoneal irritation, which progress rapidly and are easily misdiagnosed. Quick and accurate diagnosis and timely effective treatment are greatly significant in managing emergent cases. This report describes emergency rescue by a multidisciplinary team of a patient with hemorrhagic shock caused by SMA rupture. CASE SUMMARY: A 55-year-old man with hemorrhagic shock presented with SMA rupture. On admission, he showed extremely unstable vital signs and was unconscious with a laceration on his head, heart rate of 143 beats/min, shallow and fast breathing (frequency > 35 beats/min), and blood pressure as low as 20/10 mmHg (1 mmHg = 0.133 kPa). Computed tomography revealed abdominal and pelvic hematocele effusion, suggesting active bleeding. The patient was suspected of partial rupture of the distal SMA branch. The patient underwent emergency mesenteric artery ligation, scalp suture, and liver laceration closure. In view of conditions with acute onset, rapid progression, and high bleeding volume, key points of nursing were conducted, including activating emergency protocol, opening of the green channel, and arranging relevant examinations with various medical staff for quick diagnosis. The seamless collaboration of the multidisciplinary team helped shorten the preoperative preparation time. Emergency laparotomy exploration and mesenteric artery ligation were performed to mitigate hemorrhagic shock while establishing efficient venous accesses and closely monitoring the patient's condition to ensure hemodynamic stability. Strict measures were taken to avoid intraoperative hypothermia and infection. CONCLUSION: After 3.5 h of emergency rescue and medical care, bleeding was successfully controlled, and the patient's condition was stabilized. Subsequently, the patient was transferred to the intensive care unit for continuous monitoring and treatment. On the sixth day, the patient was weaned off the ventilator, extubated, and relocated to a specialized ward. Through diligent medical intervention and attentive nursing, the patient made a full recovery and was discharged on day 22. The follow-up visit confirmed the patient's successful recovery.

Efficacy of carbonic anhydrase inhibitors in management of cystoid macular edema in retinitis pigmentosa: A meta-analysis.

BACKGROUND: Carbonic anhydrase inhibitors (CAI) are often used in the treatment of cystoid macular edema (CME) in retinitis pigmentosa (RP) patients. The aim of this meta-analysis is to gain a better understanding of the overall efficacy of CAI treatment. METHODS: Databases including PubMed, EMBASE, and Cochrane Library were searched to identify relevant studies. Eligible studies were clinical trials of patients with RP assigned topical or oral CAIs such as dorzolamide and acetazolamide. Changes in central macular thickness (CMT) by OCT in µm and best-corrected visual acuity (BCVA) in log MAR equivalents were extracted and results compared between baseline and after treatment. RESULTS: 11 clinical reports were identified which included a total of 194 patients (358 eyes) available for analysis, with 59 patients (115 eyes) assigned oral CAI treatment and 135 patients (243 eyes) assigned topical CAI treatment. The combined results showed a significant reduction of macular edema, as calculated by baseline and final central macular thickness (CMT) based on OCT examination (46.02µm, 95%CI: -60.96, -31.08, I2 = 65%). However, the effect on visual acuity was inconsistent across studies. CONCLUSION: Based on non randomized controlled clinical studies, RP patients with CME who were treated with CAIs had better anatomical outcomes, but the effect on visual acuity was contradictory across studies. Multicenter prospective randomized controlled trials would be ideal to definitively test its clinical efficacy in RP patients.

[The effect of IL-10 on proliferation of primary cultured hepatocytes].

AIM: To investigate the effect of IL-10 on proliferation of rat primary cultured hepatocytes. METHODS: Rat hepatocytes were isolated from rat liver by in situ digestion of collagenase IV and cryopreserved, resuscitated, cultured in vitro. Reverse-transcription polymerase chain reaction (RT-PCR) was used to characterize the purity of hepatocytes and analyze IL-10/IL10Ralpha mRNA from freshly isolated cells. The primary cultured hepatocytes were divided into 3 groups and treated with nothing (group N), Insulin (group C), and IL-10 in combination with Insulin (group I), respectively. Nuclear cell cycle analysis, MTT, and Trypan Blue cell count was assayed. RESULTS: RT-PCR showed expression of characterization genes in primary hepatocytes group and liver tissue are different. RT-PCR showed an expression of IL-10/IL10Ralpha mRNA in rat primary hepatocytes. Trypan Blue cell count showed an depression of cell quantity in group I at 48h (71.96% contrast to group C, P<0.05). MTT analyse also showed absorbance of group I was declined contrast to group C at 24 h and 48 h (88.41% and 90.24%, P<0.05). Cell cycle analysis via FCM showed a decline at 24h in group I than group C and group N (59.06% and 70.18%, P<0.01). CONCLUSION: The primary hepatocytes we isolated is quite purity. Rat primary hepatocytes express IL-10/IL10Ralpha mRNA. IL-10 has an suppression effect on proliferation of primary cultured hepatocytes.
