Sepsis is a condition characterized by organ dysfunction resulting from the systemic inflammatory response triggered by an infection. Excessive inflammation and immunosuppression are intertwined, and severe cases may even develop into multiple organ failure. Studies have shown that indoleamine 2,3-dioxygenase 1-mediated tryptophan metabolism is involved in the occurrence and development of sepsis, and elevated plasma kynurenine levels and Kyn/Trp ratios are early indicators of sepsis development. In this paper, we provide a comprehensive summary of the role of IDO1 in the acute inflammatory phase of sepsis, late immunosuppression, and organ damage. This includes its regulation of inflammatory state, immune cell function, blood pressure, and other aspects. Additionally, we analyze preclinical studies on targeted IDO1 drugs. An in-depth understanding and study of IDO may help to understand the pathogenesis and clinical significance of sepsis and multiple organ damage from a new perspective and provide new research ideas for exploring its prevention and treatment methods.

ObjectiveThe objective is to investigate the possibility of isocenter dual-guided resetting of surface guided radiation therapy (SGRT) combined with image guided radiation therapy (IGRT) in postoperative radiotherapy for breast cancer. To assess the setup error accuracy between the new resetting mode and the traditional resetting mode. MethodsRetrospective analysis was performed on breast cancer patients who underwent ELEKTA infinity accelerator radiotherapy in sun yat-sen university cancer center from July 13, 2021 to October 15, 2022. According to different reset methods, the patients were divided into a simulation group (41 cases) and a dual-guided group (40 cases). The simulation group was reset using a simulator, CBCT scans were performed and setup errors were recorded during the first treatment; The dual-guided group was guided by AlignRT and combined with CBCT for isocenter dual-guided resetting, and the setup error obtained by CBCT registration was recorded. The global setup errors of chest region of interest (CROI) , the local residual errors of supraclavicular region of interest (SROI) and the resetting time of the two reset methods were calculated and compared respectively. The advantages of the CBCT error distribution in the dual-guided resetting of SGRT combined with IGRT were analyzed. ResultsThe median of the global setup errors (X/cm, Y/cm, Z/cm, Rx°, Ry°, Rz°) of the simulation group and the median of the dual-guided group in the CROI were statistically significant (P<0.05) except the Rz and Ry directions. The local residual errors of the two groups of the SROI were calculated. The median of the errors of X/cm, Y/cm, Z/cm, Rx°, Ry°, Rz° were statistically significant (P<0.05) except the X and Y axis. The resetting time of the simulation group was significantly longer than that of the dual-guided group (238.64±28.56) s, t=-24.555, P=0.000, and the difference was statistically significant (P<0.05). The CBCT error distribution of the dual-guide group was analyzed, and it was found that the absolute values of translation errors of X, Y and Z axis were all within 0.4 cm, while the proportions of ≤ 0.3 cm were 95%, 93% and 93%, respectively. The proportions of rotation errors of Rx, Ry and Rz ≤ 1.5 ° were 90%, 93% and 90%, respectively. ConclusionIn postoperative radiotherapy of breast cancer, SGRT combined with IGRT for isocenter dual-guided resetting can effectively correct the rotational setup errors and residual errors, and improve the accuracy of radiotherapy with less resetting time and high feasibility, which compared with the traditional simulator resetting mode. This precise, unmarked resetting method can be widely used in clinical practice.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Many therapies are effective in treating varicoceles, including dilation of the pampiniform plexus in males. The most common method of treatment is varicocelectomy. We aimed to assess an alternative technique (microsurgical spermatic [distal end]-superficial or inferior epigastric vein anastomosis) that preserves the normal blood flow pattern for varicocele treatment. We retrospectively analyzed 27 men with varicocele between October 2019 and July 2020. All patients underwent microsurgical spermatic (distal end)-superficial or inferior epigastric vein anastomosis. The prognosis was reviewed retrospectively with an additional survey conducted 3 months after surgery. The mean ± standard deviation of the age was 26.1 ± 7.3 years in patients with microsurgical spermatic (distal end)-superficial or inferior epigastric vein anastomosis. The maximum diameter of the varicocele vein, perineal pain score, sperm density, and forward movement of sperm improved over 3 months after surgery. Microsurgical spermatic (distal end)-superficial or inferior epigastric vein anastomosis is a safe and efficient surgical treatment for varicoceles.

【Objective】 Thrombelastogram(TEG) was used to detect the blood clotting function of patients with esophageal cancer in each stage of perioperative period, so as to understand the change pattern of blood clotting function in patients with esophageal cancer during perioperative period, and to guide the postoperative anticoagulation or hemostasis treatment. 【Methods】 Sixty patients diagnosed with esophageal cancer who underwent surgical treatment between May 2017 and May 2019 in Jiangmen Central Hospital were selected as the experimental group, and 60 cases of healthy physical examination were selected as the normal control group. By contrasting with the normal control group, results of blood sample testing for the experimental group 1 day before, 1 day after operation, and the 7th day postoperative thrombosis elastic figure were used to analyze the change of the esophageal perioperative blood coagulation function. 【Results】 Compared with the control group before surgery, the TEG parameters R, K and LY30 decreased, and Angle, MA and CI increased, with statistically significant differences(P < 0.05). Compared with the normal control group after surgery, the R and K values of TEG parameters in the experimental group decreased significantly, while Angle, MA and CI values increased significantly, with statistically significant differences(P < 0.01), and LY30 values decreased, with statistically significant differences(P < 0.05). Compared with the experimental group before and after surgery, the TEG parameters R and K decreased, and the values of LY30, Angle, MA and CI increased, with no statistically significant difference(P > 0.05). Seven days after the operation and 1 day after the operation, the values of R and K of TEG decreased, and the values of MA and CI increased, with statistically significant differences(P < 0.05) . 【Conclusion】 All patients with esophageal cancer presented hypercoagulability before and after operation.Surgery and anesthesia did not significantly change the coagulation status of esophageal cancer. In the postoperative recovery process, the hypercoagulable state will be more obvious.

Objective: To determine the frequency of anti-HCV antibody positivity in patients with non-liver disease complaints, to explore whether anti-HCV positive patients had been properly advised and visited hepatologists for further assessments, and to investigate their clinical characteristics as well as the HCV treatment status. Methods: A hospital based survey of non-liver disease patients with anti-HCV positive and their attending physicians was conducted to determine: 1. were the patients adequately advised of the implication of anti-HCV positive finding; 2. to what extent the patients were aware of potential chronic liver disease associated with HCV infection and whether they sought for further assessments and care of hepatologists. Results: A total of 295 294 non-liver disease patients were tested for anti-HCV antibody, and 2 778 of them were found to be positive (0.94%). However, only 45.10% (1 253/2 778) of the anti-HCV antibody (+) patients were referred to hepatologists and received HCV RNA test. In addition, 34.10% (312/915) and 1.42% (13/915) of them had already advanced to cirrhosis and hepatocellular carcinoma (HCC), respectively. Further analysis showed that the patients who declined antiviral therapy were older, with lower education and lower income, possessed poorer knowledge on the risk of chronic hepatitis C, and had more severe liver diseases. Surprisingly, 65% of the surveyed physicians did not know the genotype-guided treatment duration suggested by the guidelines. Alarmingly, 22% of the surveyed physicians did not know the standard assays for the diagnosis of HCV infection. Conclusions: Our findings highlight the challenge and hidden enormous burden of chronic HCV infection among patients with non-liver disease complaints in China.

Objective:
To observe the synergistic effect of Qilan Capsules in the treatment of the patient with Qi-deficiency blood-stasis type of prostate cancer receiving androgen-deprivation therapy after castration.
METHODS:
This randomized controlled double-blind study included 246 cases of Qi-deficiency blood-stasis type of prostate cancer after castration, which were randomly divided into an experiment and a control group of equal number to be treated with Qilan Capsules + androgen-deprivation and placebo + androgen-deprivation, respectively. After 6 months of treatment, we compared the International Prostate Symptoms Scores (IPSS), TCM Symptoms Scores (TCMSS), maximal urine flow rate (Qmax), and the level of serum prostate-specific antigen (PSA) between the two groups of patients.
RESULTS:
Statistically significant differences were observed between the experiment and control groups in the syndrome classification-based efficacy (87.7% vs 67.9%, P <0.05) and total effectiveness rate (86.0% vs 71.6%, P <0.05). Compared with the baseline, the experiment group showed remarkable improvement after treatment in TCMSS (17.1±5.1 vs 8.3±4.0, P <0.05), IPSS (17.7±7.5 vs 11.4±4.6, P <0.05), and Qmax ([10.9±4.3] ml/s vs [14.7±3.7] ml/s, P <0.05), and so did the control group (16.8±5.2 vs 11.5±5.2, 17.8±6.7 vs 14.6±5.8, and [11.0±4.3] ml/s vs [12.0±4.1] ml/s, P <0.05). The above three parameters were even more markedly improved in the former than in the latter group (P <0.05). However, there was no statistically significant difference between the two groups in the improvement of the PSA level after treatment (P >0.05).
CONCLUSIONS
Qilan Capsules can significantly enhance the effect of androgen-deprivation therapy in the treatment of Qi-deficiency blood-stasis type of prostate cancer after castration though cannot obviously improve the PSA level.
