Objective: To explore the feasibility and safety of the gasless transoral vestibular robotic thyroidectomy using skin suspension. Methods: The clinical data of 20 patients underwent gasless transoral vestibular robotic thyroidectomy in the Department of Otorhinolaryngology, Sun Yat-sen Memorial Hospital, Sun Yat-sen University from February 2022 to May 2022 were retrospectively analyzed. Among them, 18 were females and 2 were males, aged (38.7±8.0) years old. The intraoperative blood loss, operation time, postoperative hospital stay, postoperative drainage volume, postoperative pain visual analogue scale (VAS) score, postoperative swallowing function swallowing impairment score-6 (SIS-6), postoperative aesthetic VAS score, postoperative voice handicap index-10 (VHI-10) voice quality, postoperative pathology and complications were recorded. SPSS 25.0 was used for statistical analysis of the data. Results: The operations were successfully completed without conversion to open surgery in all patients. Pathological examination showed papillary thyroid carcinoma in 18 cases, retrosternal nodular goiter in 1 case, and cystic change in goiter in 1 case. The operative time for thyroid cancer was 161.50 (152.75, 182.50) min [M (P₂₅, P₇₅), the same below] and the average operative time for benign thyroid diseases was 166.50 minutes. The intraoperative blood loss 25.00 (21.25, 30.00) ml. In 18 cases of thyroid cancer, the mean diameter of the tumors was (7.22±2.02) mm, and lymph nodes (6.56±2.14) were dissected in the central region, with a lymph node metastasis rate of 61.11%. The postoperative pain VAS score was 3.00 (2.25, 4.00) points at 24 hours, the mean postoperative drainage volume was (118.35±24.32) ml, the postoperative hospital stay was 3.00 (3.00, 3.75) days, the postoperative SIS-6 score was (4.90±1.58) points at 3 months, and the postoperative VHI-10 score was 7.50 (2.00, 11.00) points at 3 months. Seven patients had mild mandibular numbness, 10 patients had mild cervical numbness, and 3 patients had temporary hypothyroidism three months after surgery and 1 patient had skin flap burn, but recovered one month after surgery. All patients were satisfied with the postoperative aesthetic effects, and the postoperative aesthetic VAS score was 10.00 (10.00, 10.00). Conclusion: Gasless transoral vestibular robotic thyroidectomy using skin suspension is a safe and feasible option with good postoperative aesthetic effect, which can provide a new treatment option for some selected patients with thyroid tumors.

OBJECTIVE: To investigate the expression of MC1R in esophageal squamous cell carcinoma and its correlation with the clinicopathological parameters. METHODS: We analyzed the expression of MC1R in esophageal cancer based on data from TCGA databse and examined its expression levels using RT-PCR and Western blotting in a human esophageal epithelial cell line BAr-T, human esophageal squamous cell carcinoma cell lines ECA109, KYSE30, KYSE150, KYSE510, TE-1, TE-13, and EC9706, a human gastric cancer cell line SGC7901 and 19 pairs of esophageal squamous cell carcinoma tissues and adjacent tissues.Immunohistochemistry was used to detect MC1R expression levels in 32 pairs of paraffin-embedded sections of esophageal squamous cell carcinoma and adjacent tissues, and the correlation of MC1R expression and the patients'clinicopathological characteristics was analyzed. RESULTS: Bioinformatics analysis showed that MC1R was significantly overexpressed in esophageal cancer tissues (P < 0.05).MC1R expression was also increased in 5 esophageal squamous cell carcinoma cell lines ECA109, KYSE30, KYSE510, TE-13, EC9706 and the gastric cancer cell line SGC7901 as compared with that in esophageal epithelial cells (P < 0.05).Immunohistochemistry revealed significantly increased MC1R expression in esophageal squamous cell carcinoma tissue sections in comparison with the adjacent tissue sections (P < 0.05).In patients with esophageal squamous cell carcinoma, a high MC1R expression was detected mainly in those with an old age, positive for middle-thoracic involvement, and with moderately differentiated tumor cells, and showed a correlation with T stage of tumor (P < 0.05), but not with the other clinicopathological parameters such as gender, age, degree of cell differentiation, primary tumor site, or TNM stage (P>0.05). CONCLUSION MC1R is highly expressed in esophageal squamous cell carcinoma and may serve as a molecular biomarker to assist in the diagnosis of esophageal squamous cell carcinoma.

Aurantii Fructus is a commonly used qi-regulating medicinal herb in China. Both traditional Chinese medicine theory and modern experimental research demonstrate that Aurantii Fructus has dryness effect, the material basis of which remains unclear. In recent years, spectrum-effect relationship has been widely employed in the study of active ingredients in Chinese medicinal herbs, the research ideas and methods of which have been constantly improved. Based on the idea of spectrum-effect study, the ultra-high perfor-mance liquid chromatography-quadrupole-time of flight mass spectrometry(UHPLC-Q-TOF-MS) fingerprints of different fractions of Aurantii Fructus extract were established for the identification of total components. Then, the dryness effects of the fractions on normal mice and gastrointestinal motility disorder(GMD) rats were systematically compared. Finally, principal component analysis(PCA), Pearson bivariate correlation analysis and orthogonal partial least squares analysis(OPLS) were integrated to identify the dryness components of Aurantii Fructusextract. The results showed that narirutin, naringin, naringenin, poncirin, oxypeucedanin, and eriodictyol-7-O-glucoside had significant correlations with and contributed to the expression of AQP2 in kidney, AQP3 in colon, and AQP5 in submandibular gland, which were the main dryness components in Aurantii Fructus.

Recently, suppressor of cytokine signaling-3 (SOCS3) has been shown to be an inducible endogenous negative regulator of Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway which is relevant in inflammatory response, while its functions in acute liver failure and HBV-induced acute-on-chronic liver failure (HBV-ACLF) have not been fully elucidated. In this study, we explored the role of SOCS3 in the development of mouse hepatitis virus strain 3 (MHV-3)-induced acute liver failure and its expression in liver and peripheral blood mononuclear cells (PBMCs) of patients with HBV-ACLF. Inflammation-related gene expression was detected by real-time PCR, immunohistochemistry and Western blotting. The correlation between SOCS3 level and liver injury was studied. Our results showed that the SOCS3 expression was significantly elevated in both the liver tissue and PBMCs from patients with HBV-ACLF compared to mild chronic hepatitis B (CHB). Moreover, a time course study showed that SOCS3 level was increased remarkably in the liver of BALB/cJ mice at 72 h post-infection. Pro-inflammatory cytokines, interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α, were also increased significantly at 72 h post-infection. There was a close correlation between hepatic SOCS3 level and IL-6, and the severity of liver injury defined by alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, respectively. These data suggested that SOCS3 may play a pivotal role in the pathogenesis of MHV-3-induced acute liver failure and HBV-ACLF.

OBJECTIVETo investigate the safety of assisted reproductive technology (ART) with donated sperm from the sperm bank and the differences in the pregnancy outcomes of different means of promoting pregnancy.

METHODSWe analyzed and compared the feedback data on promoting pregnancy with donated sperm from the sperm bank by artificial insemination by donor (AID), in vitro fertilization (IVF), and intracytoplasm sperm injection (ICSI).

RESULTSTotally, 13 723 tubes of sperm specimens were used for ART. The number of specimens used differed in different clinical reproductive centers, some using 1 tube and others using 2 tubes per cycle. The 13 723 tubes were used for a total of 7 743 cycles. Among the 7 123 cycles of AID, there were 1 415 clinical pregnancies (19.87%), 1 221 normal births (86.29%), 169 abortions (11.94%), 6 cases of birth defects (0.43%), 19 ectopic pregnancies (1.34%), and 0 sexually transmitted infection. Among the 571 cycles of IVF, there were 367 clinical pregnancies (64.27%), 330 normal births (89.92%), 35 abortions (9.54%), 0 birth defect, 2 ectopic pregnancies (0.54%), and 0 sexually transmitted infection. Among the 49 cycles of ICSI, there were 28 clinical pregnancies (57.14%), 25 normal births (89.29%), 3 abortions (10.71%), 0 birth defect, 0 ectopic pregnancy, and 0 sexually transmitted infection. There were statistically significant differences in the rate of clinical pregnancy among AID, IVF and ICSI (P < 0.05), but not between IVF and ICSI (P > 0.05), nor were there any significant differences in the rates of abortion, birth defects and ectopic pregnancy among AID, IVF and ICSI (P > 0.05).

CONCLUSIONNone of the recipients of the donated sperm from the sperm bank was infected with sexually transmitted diseases. AID, IVF and ICSI showed no significant differences from natural conception in the rates of abortion, birth defects and ectopic pregnancy. ART with donated sperm from the sperm bank is safe. IVF and ICSI are associated with a higher rate of pregnancy than AID, though the latter costs less than the former two.

BACKGROUNDAcute kidney injury (AKI) has been recognized as a major healthcare problem affecting millions of patients worldwide. However, epidemiologic data concerning AKI in China are still lacking. The objectives of this study were to characterize AKI defined by RIFLE criteria, assess the association with hospital mortality, and evaluate the impact of AKI in the context of other risk factors.

METHODSThis prospective multicenter observational study enrolled 3,063 consecutive patients from 1 July 2009 to 31 August 2009 in 22 ICUs across mainland China. We excluded patients who were admitted for less than 24 hours (n = 1623), younger than 18 years (n = 127), receiving chronic hemodialysis (n = 29), receiving renal transplantation (n = 1) and unknown reasons (n = 28). There were 1255 patients in the final analysis. AKI was diagnosed and classified according to RIFLE criteria.

RESULTSThere were 396 patients (31.6%) who had AKI, with RIFLE maximum class R, I, and F in 126 (10.0%), 91 (7.3%), and 179 (14.3%) patients, respectively. Renal function deteriorated in 206 patients (16.4%). In comparison with non AKI patients, patients in the risk class on ICU admission were more likely to progress to the injury class (odds ratio (OR) 3.564, 95% confidence interval (CI) 1.706 - 7.443, P = 0.001], while patients in the risk class (OR 5.215, 95% CI 2.798-9.719, P < 0.001) and injury class (OR 13.316, 95% CI 7.507-23.622, P < 0.001) had a significantly higher probability of deteriorating into failure class. The adjusted hazard ratios for 90-day mortality were 1.884 for the risk group, 3.401 for the injury group, and 5.306 for the failure group.

CONCLUSIONSThe prevalence of AKI was high among critically ill patients in Chinese ICUs. In comparison with non-AKI patients, patients with RIFLE class R or class I on ICU admission were more susceptibility to progression to class I or class F. The RIFLE criteria were robust and correlated well with clinical deterioration and mortality.

BACKGROUNDThe nocturnal nondipping and elevated morning blood pressure (BP) in patients with obstructive sleep apnea syndrome (OSAS) have not yet been well investigated in Chinese patients. This study aimed to describe the BP profile, and to elucidate the relationships between daytime BP and nighttime BP, and between evening BP and morning BP in patients with OSAS.

METHODSTwenty teaching hospital sleep centers in China were organized by the Chinese Medical Association to participate in this study and 2297 patients were recruited between January 2004 and April 2006. BP assessments were made at four time points (daytime, evening, nighttime and morning) and polysomnography (PSG) was performed and subjects were classified into four groups by their apnea-hypopnea index (AHI): control, n = 213 with AHI < 5; mild, n = 420 with AHI ≥ 5 and < 15; moderate, n = 460 with AHI ≥ 15 and < 30; and severe, n = 1204 with AHI ≥ 30. SPSS 11.5 software package was used for statistical analysis and figure drawing.

RESULTSAll the average daytime, nighttime, evening and morning BPs were positively correlated with AHI and negatively correlated with nadir nocturnal oxygen saturation. The ratios of nighttime/daytime and morning/evening average BP were positively correlated with AHI. The ratio of nighttime/daytime systolic BP became a "reversed BP dipping" pattern until the classification reached severe, while the ratio of nighttime/daytime diastolic BP became reversed at moderate. Similarly, the ratio of morning/evening diastolic BP becomes reversed even at mild.

CONCLUSIONSOSAS may result in higher BP levels at all four time points. The ratios of nighttime/daytime and morning/evening BP increase with increased AHI. The increasing of diastolic BP, which is inclined to rise more quickly, is not parallel with increasing systolic BP.
