Objective To investigate the dynamics of NK cells and Treg cells,as well as their potential prognostic significance in relation to TKI discontinuation among patients diagnosed with chronic myeloid leukemia(CML).Methods In this study,a total of 200 patients diagnosed with CML were randomly selected and divided into two groups:the discontinuation group(n=100)and the non-discontinuation group(n=100).Within the discontinuation group,patients were further categorized into a recurrence subgroup(n=41)and a non-recurrence subgroup(n=59).Clinical data and follow-up information of these patients were retrospectively analyzed.Logistic regression analysis was performed to investigate the impact of various variables on patient outcomes following drug discontinuation,as well as to explore independent factors influencing recurrence in these individuals.Receiver operating characteristic(ROC)curve analysis was employed to assess the predictive value of NK cells and Treg cells for TKI discontinuation outcomes.A significance level of P<0.05 was considered statistically significant.Results The proportion of patients treated with interferon in the discontinuation group was significantly higher than that in the non-discontinuation group(P<0.05).Moreover,the former group exhibited a significantly higher number of NK cells(P<0.05)and Treg cells(P<0.01)compared to the latter group.Compared to the recurrence group,there was a significant increase in the proportion of patients using interferon in the non-recurrence group(P<0.05),along with longer durations of TKI treatment and deep molecular response(DMR)duration(P<0.05).The number of NK cells and Treg cells in the non-recurrence group was significantly higher than that in the recurrence group(P<0.01).Logistic regression analysis found that the use of interferon(OR=1.25,95%CI:1.11～2.03,P<0.001),duration of DMR(OR=1.16,95%CI:1.08～1.92,P<0.05),NK cells(OR=1.64,95%CI:1.14～2.28,P<0.01),and Treg cells(OR=1.83,95%CI:1.15～2.42,P<0.01)were all influencing factors for the recurrence of patients after drug discontinuation.The results of ROC curve analysis showed that the AUC of NK cells combined with Treg cells for predicting the recurrence of TKI after discontinuation was 0.892(95%CI:0.857～0.927,P<0.001).Conclusion The frequencies of NK cells and Treg cells were significantly elevated in patients who remained recurrence-free following TKI discontinuation,highlighting the potential predictive value of combined NK cell and Treg cell analysis for drug cessation in CML patients.

Objective:To explore the regulatory effect of Suaeda salsa on renal apoprosis inhibitor of macrophage (AIM) and macrophage polarization in diabetes kidney disease (DKD) model rats.Methods:A DKD rat model was established using a high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin (STZ). The rats were divided into model group, metformin group, and Suaeda salsa high-, medium-, and low-dosage groups using a random number table method, with 8 mice in each group. The normal group was set with 8 rats in this group. The metformin group was given 85.71 mg/kg of metformin solution by gavage, while the Suaeda salsa high-, medium-, and low-dosage groups were given 3.08, 1.54, and 0.77 g/kg of Suaeda salsa suspension by gavage (raw dosage). The normal group and model group were given equal volumes of saline by gavage, once a day, administered by gavage for 12 weeks of intervention. Fasting blood glucose (FBG) and glucose tolerance (OGTT) were measured, and the area under the curve (AUC) was calculated; the levels of glycosylated hemoglobin (HbA1c) and glycosylated serum protein (GSP) were detected; urea nitrogen (BUN), serum creatinine (SCr), and 24-hour urine protein (24 hUP) were detected; HE staining was used to observe the pathological morphology of the kidneys; Masson and PAS staining were used to observe renal tissue fibrosis; Western blot method was used for detecting AIM, CD206, CD86, TNF-α and IL-10 protein levels in renal tissue; Immunofluorescence was used to detect the average optical density values of AIM, CD206, and CD86 proteins in renal tissue.Results:Compared with the model group, the FBG, OGTT AUC, HbA1c, GSP of each dosage group of Suaeda salsa decreased ( P<0.01); the expression levels of AIM, CD206, and IL-10 proteins in renal tissue increased ( P<0.01 or P<0.05), while the expression levels of CD86 and TNF-α protein significantly decreased ( P<0.01 or P<0.05); HE, Masson, and PAS staining results showed that compared with the model group, the changes in renal microvasculature and renal fibrosis of rats in each dosage group of Suaeda salsa were improved. Conclusion:Suaeda salsa may regulate AIM, promote polarization of M2 macrophages, improve the inflammatory microenvironment of macrophages, thereby lowering blood lipids of DKD rats, and improving renal pathological damage.

Objective:To investigate outcomes and safety of doxycycline-moxifloxacin sequential regimen in the treatment of Mycoplasma genitalium urethritis/cervicitis. Methods:From June 2019 to December 2020, patients with Mycoplasma genitalium urethritis/cervicitis confirmed by nucleic acid amplification testing were successively recruited at Department of Sexually Transmitted Diseases, Hospital of Dermatology, Chinese Academy of Medical Sciences, and received sequential therapy with oral doxycycline for 7 days followed by oral moxifloxacin for 7 days. Clinical and/or etiological assessment was conducted 2 to 3 weeks after the end of treatment. Fisher′s exact test was used to analyze factors influencing the treatment outcome. Results:Totally, 36 eligible subjects were enrolled, including 30 males and 6 females. Among them, 18 (50%) patients completed post-treatment etiological assessment, which showed that 12 achieved microbiological cure, and treatment failures occurred in 6; another 18 patients achieved clinical cure. The overall response rate to doxycycline-moxifloacin sequential therapy was 83.3% (30/36, 95% confidence interval[ CI]: 70.5%, 96.1%) . The treatment outcome showed no significant association with the patients′ age, gender, marital status, number of sexual partners in the past 1 month, history of sexually transmitted diseases, history of antibiotic use in the past 1 month, or co-infections (all P > 0.05) . Conclusion:The efficacy of doxycycline-moxifloacin sequential regimen is limited in the treatment of Mycoplasma genitalium infections in Nanjing area, and clinicians should be alerted to the possibility of treatment failure in clinical practice.

Objective:To study the clinical manifestations and prognosis of patients with liver perivascular epithelioid cell tumor (PEComa).Methods:The clinical manifestations, imaging findings, pathological features, treatment and prognosis of 17 patients with liver PEComa managed in Shenzhen People's Hospital from September 2002 to January 2020 were retrospectively analysed.Results:The patient age of onset of liver PEComa was 22 to 54 years (average 34.8 years). There were 13 females and 4 males. 82%(14/17) of patients presented with no significant symptoms. 15/17 had solitary tumors. The diagnostic rate using preoperative B-ultrasound, CT and MRI was low. Postoperative pathological studies showed the tumor cells were mainly epithelioid cells with hyaline or eosinophilic cytoplasm. There were abundant blood vessels in the tumor tissues. Adipose tissues were also seen. Immunohistochemistry showed both HMB45 and Melan-A positivities to arrive at the diagnosis. All patients were treated with surgical resection. There were no recurrence, metastasis, or death on follow-up.Conclusion:Hepatic PEComa occurred more frequently in young women and it had no specific clinical manifestations. Except for a small number of tumors with adipose tissue detected on preoperative imagings, this tumor was difficult to diagnose, or even be suspected on preoperative imagings. Pathological examination combined with immunohistochemistry after surgery established the diagnosis. Surgery resulted in good prognosis.
