Objective To compare the application effect of intermittent androgen deprivation(IAD)and continued androgen deprivation(CAD)on advanced prostate cancer and influence on prognosis.Methods The patients with advanced prostate cancer were divided into treatment group(86 cases)and control group(62 cases)according to the cohort method.The treatment group was given IAD regimen(subcutaneous injection of 3.6 mg goserelin once every 28 days)combined with oral administration of flutamide(250 mg every 3 times a day)or combined with oral administration of bicalutamide(50 mg once a day),and the control group was treated with CAD regimen(bilateral orchiectomy combined with continuous flutamide or bicalutamide orally,with the same dosage as the treatment group).The observation follow-up time of both groups was ≥9 months.Efficacy,serum total testosterone(TT),prostate specific antigen(PSA)and vascular endothelial growth factor(VEGF)were compared between the two groups after treatment,and the side effects of treatment,quality of life[Functional Assessment of Cancer Therapy-Prostate(FACT-P)]and disease progression were evaluated.Results At 9 months after treatment,the objective response rates(ORR)in treatment group and control group were 30.99％(22 cases/71 cases)and 29.09％(16 cases/55 cases),and the disease control rates(DCR)were 71.83％(51 cases/71 cases)and 69.09％(38 cases/55 cases)respectively(P＞0.05).Serum TT levels in treatment group and control group were(25.53±9.44)and(22.51±8.28)ng·dL-1,PSA levels were(4.48±1.02)and(4.32±0.95)ng·mL-1,and VEGF levels were(121.03±35.26)and(118.65±33.42)pg·mL-1 respectively(all P＞0.05).The incidence rates of hot flash in treatment group and control group were 21.13％and 56.36％,the incidence rates of breast swelling pain were 16.90％and 34.55％,and the incidence rates of osteoporosis were 8.45％and 25.45％respectively(all P＜0.05).The scores of physical condition of FACT-P in treatment group and control group were(24.15±4.22)and(20.28±3.71)points,the scores of life condition were(20.28±2.94)and(17.81±2.84)points,scores of prostate cancer specific(PCS)module were(33.21±6.32)and(28.42±5.43)points,respectively,the difference were all statistically significant(all P＜0.05).The cumulative progression-free survival rates in treatment group and control group were 61.97％and 58.18％(P＞0.05).Conclusion IAD is as effective as CAD in the treatment of advanced prostate cancer and has a similar effect on the prognosis of patients,but the former one has fewer side effects of treatment and helps to improve the quality of life of patients.

Objective:To study the early predictors of refractory septic shock (RSS) in neonates.Methods:From July 2020 to December 2021, clinical data of neonates with septic shock admitted to the Neonatal Department of our hospital were retrospectively reviewed. According to the maximum septic shock score (SSS) during clinical course, the neonates were assigned into RSS group and non-RSS group. Perinatal data, laboratory results and hemodynamic parameters at diagnosis were compared between the two groups. Multiple logistic regression analysis was used to identify independent risk factors of RSS and septic shock-related death. Receiver operating characteristic (ROC) curve was constructed to evaluate the early predictors of poor prognosis.Results:A total of 130 neonates were enrolled, including 54 in RSS group and 76 in non-RSS group. Compared with the non-RSS group, the RSS group had significantly lower pH, base excess (BE), stroke volume index (SVI), cardiac output (CO) and cardiac index (CI).Meanwhile, the RSS group had significantly higher mean arterial pressure (MAP) to CI ratio (MAP/CI) and SSS [including bedside SSS (bSSS), computed SSS (cSSS) and modified version of cSSS (mcSSS)] (all P<0.05). Multiple logistic regression analysis showed that increased MAP/CI was an independent predictor of RSS. The cut-off value of MAP/CI was 11.6 [sensitivity 62%, specificity 87%, positive predictive value (PPV) 79% and negative predictive value (NPV) 77%], with an area under the curve (AUC) of 0.734. Increased mcSSS was an independent predictor of septic shock-related death. The cut-off value of mcSSS was 5.8 (sensitivity 83%, specificity 72%, PPV 21% and NPV 97%), with an AUC of 0.845. Conclusions:Increased MAP/CI (≥11.6) and mcSSS (≥5.8) may be early predictors of RSS and septic shock-related death in neonates.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Objective To observe the effect of Bushen Jianpi Prescription,a prescription with the actions of tonifying the kidney and strengthening the spleen,combined with short-term intensive insulin therapy on dedifferentiation of pancreatic beta-cells in patients with type 2 diabetes mellitus(T2DM)of spleen and kidney deficiency type.Methods Seventy patients with T2DM of spleen and kidney deficiency type were randomly divided into control group and observation group,with 35 cases in each group.The control group was treated with intensive insulin therapy,and the observation group was treated with Bushen Jianpi Prescription on the basis of treatment for the control group.The course of treatment lasted for 2 weeks.The changes of TCM syndrome score,and levels of blood glucose,serum high mobility group protein B1(HMGB1),interleukin 1β(IL-1β),tumor necrosis factor α(TNF-α)and the ratio of proinsulin to insulin(PI/I)in the two groups were observed before and after treatment.Results(1)During the treatment,one case in the control group and 2 cases in the observation group fell off.Eventually,34 cases in the control group and 33 cases in the observation group were included in the efficacy statistics.(2)After treatment,the scores of TCM syndromes in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the levels of fasting plasma glucose(FPG)and 2-hour postprandial plasma glucose(2hPG)in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the level of HMGB1 in the two groups was significantly lower than that before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the serum levels of inflammatory factors of IL-1β and TNF-α in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(6)After treatment,the PI/I ratio of the two groups was significantly lower than that before treatment(P＜0.05),and the decrease of the observation group was significantly superior to that of the control group(P＜0.05).Conclusion Bushen Jianpi Prescription combined with short-term intensive insulin therapy can effectively improve the islet function of patients with T2DM of spleen and kidney deficiency type.The mechanism may be related to the relief of high-glucose toxicity and the decrease of the inflammatory factor levels,thus to inhibit the dedifferentiation of pancreatic beta-cells.

Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ²=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

Objective:To study the predictive value of vasoactive-inotropic score (VIS), fluid overload (FO) and lactate level for the outcome of preterm infants with refractory septic shock.Methods:Preterm infants diagnosed with refractory septic shock and required hydrocortisone treatment in our Department from January 2016 to December 2021 were analyzed retrospectively. Preterm infants were assigned into three gestational age groups (<28 weeks, 28-31 weeks, 32-36 weeks). According to the outcome of the disease, the children were further divided into good prognosis group and poor prognosis group. The relationship between the maximum VIS, FO and the mean lactic acid before hydrocortisone and the outcome of refractory septic shock was analyzed by receiver operating characteristic (ROC) curve, the cut-off point of ROC curve was calculated to obtain the predictive efficacy of the three indicators for the outcome of refractory septic shock in preterm infants.Results:A total of 50 preterm infants with refractory septic shock and received hydrocortisone treatment were enrolled, including 20 in the good prognosis group and 30 in the poor prognosis group. There were no significant differences in the maximum VIS, FO and mean lactic acid before hydrocortisone treatment between the two groups of gestational age of <32 weeks ( P> 0.05). The maximum VIS, FO and mean lactic acid of gestational age of 32-36 weeks in the poor prognosis group were higher than those in the good prognosis group, VIS: 56.1±15.7 vs. 37.1±12.9, FO (%): 108.2 (78.6,137.7) vs. 55.5 (10.3, 100.7), and mean lactic acid (mmol/L): 8.3 (4.6, 12.0) vs. 4.8 (-0.8, 10.5), all P<0.05. The area under the ROC curve of the mean lactic acid was the largest, the cut-off value was 4.1 mmol/L, and the Youden index was 1.732. Conclusions:VIS, FO and lactate level are difficult to be used for determining the outcome of refractory septic shock in preterm infants of <32 weeks. While the mean lactic acid has the best predictive performance in preterm infants of 32-36 weeks.

Objective: To assess the feasibility of using donors with novel coronavirus disease 2019 (COVID-19) for allogeneic hematopoietic stem cell transplantation (allo-HSCT) when there are no other available donors and allo-HSCT cannot be delayed or discontinued. Methods: Seventy-one patients with malignant hematological diseases undergoing allo-HSCT between December 8, 2022, and January 10, 2023, were included. Of these, 16 received grafts from donors with mild COVID-19 (D-COVID(+) group) and 55 received grafts from donors without COVID-19 (D-COVID(-) group). The graft compositions were compared between the two groups. Engraftment, acute graft-versus-host disease (aGVHD), overall survival (OS), and relapse were also evaluated. Results: There were no serious side effects or adverse events in the D-COVID(+) group. The mononuclear cell dose and CD34(+) cell dose were comparable between the two groups, and no additional apheresis was required. There were no significant differences in the lymphocyte, monocyte, and T-cell subset doses between the two groups. The median natural killer cell dose in the D-COVID(+) group was significantly higher than that in the D-COVID(-) group (0.69×10(8)/kg vs. 0.53×10(8)/kg, P=0.031). The median follow-up time was 72 (33-104) days. All patients achieved primary engraftment. The 60-day platelet engraftment rates in the D-COVID(+) and D-COVID(-) groups were 100% and (96.4±0.2) %, respectively (P=0.568). There were no significant differences in neutrophil (P=0.309) and platelet (P=0.544) engraftment times. The cumulative incidence of grade 2-4 aGVHD was (37.5±1.6) % vs. (16.4±0.3) % (P=0.062), and of grade 3-4 aGVHD was 25.0% ±1.3% vs. 9.1% ±0.2% (P=0.095) in the D-COVID(+) and D-COVID(-) groups, respectively. The probabilities of 60-day OS were 100% and 98.1% ±1.8% (P=0.522) in the D-COVID(+) and D-COVID(-) groups, respectively. There was no relapse of primary disease during the study period. Conclusion: When allo-HSCT cannot be delayed or discontinued and no other donor is available, a donor with mild COVID-19 should be considered if tolerable. Larger sample sizes and longer follow-up periods are required to validate these results.

Objective:To explore the effect of quality improvement of hemodynamic monitoring on fluid overload (FO) and outcome in newborns with septic shock.Methods:Non-invasive cardiac output monitoring and functional cardiac ultrasound quality improvement program was started during January 2020 in our hospital. Neonates with septic shock admitted before and after the program were retrospectively analyzed. From January 2018 to December 2019 was pre-improvement period when fluid resuscitation was routinely performed and vasoactive drugs was selected empirically. From January 2020 to December 2021 was post-improvement period when fluid resuscitation and/or use and adjustment of vasoactive drugs were guided by hemodynamic parameters. The 24 h, 48 h, 72 h FO, duration of invasive respiratory support, vasoactive-inotropic score, septic shock score, incidences of complications and all-cause mortality were compared between the two groups.Results:A total of 284 eligible cases were enrolled, including 136 cases in pre-improvement group and 148 cases in post-improvement group. Post-improvement group had significantly lower gestational age (GA), birth weight (BW) and body weight at disease onset than pre-improvement group ( P<0.05). Incidences of 48 h and 72 h FO, fluid resuscitation volume within 72 h, pulmonary hemorrhage and periventricular leukomalacia (PVL) were significantly lower in the post-improvement group ( P<0.05). No significant differences existed in 24 h FO, other complications and all-cause mortality between the two groups ( P>0.05). No significant differences existed in GA and BW for neonates with pulmonary hemorrhage and PVL between the two groups ( P>0.05). Conclusions:Quality improvement of hemodynamic monitoring can effectively improve FO and reduce the incidences of pulmonary hemorrhage and PVL.

OBJECTIVES: To study the value of functional echocardiographic parameters in predicting refractory septic shock in neonates. METHODS: A total of 72 neonates with septic shock were enrolled. According to the highest value of septic shock score, they were divided into two groups: refractory (n=30) and non-refractory (n=42). The two groups were compared in terms of clinical data, laboratory findings, and functional echocardiographic parameters. The receiver operating characteristic (ROC) curve was used to evaluate the performance of functional echocardiographic parameters in predicting refractory septic shock. RESULTS: Compared with the non-refractory group, the refractory group had significantly lower cardiac output and cardiac index (CI) and a significantly higher mean arterial pressure (MAP)/CI ratio (P<0.05). CI had a cut-off value of 2.6 L/(min·m²), a sensitivity of 79%, a specificity of 83%, and an area under the ROC curve (AUC) of 0.841 in predicting septic shock-related death (P<0.05), and MAP/CI ratio had a cut-off value of 11.4, a sensitivity of 83%, a specificity of 73%, and an AUC of 0.769 (P<0.05). CI had a cut-off value of 2.9 L/(min·m²), a sensitivity of 69%, a specificity of 69%, and an AUC of 0.717 in predicting all-cause death within 28 days (P<0.05). CONCLUSIONS CI and MAP/CI ratio can be useful for early prediction of septic shock-related death in neonates.

Objective:To study the efficacy of norepinephrine in the treatment of neonates with septic shock.Methods:A prospective observation study of neonates with septic shock, who received norepinephrine in the neonatal intensive care unit of Guangdong Women and Children's Hospital from January 2019 to November 2020. All infants had functional echocardiography for hemodynamic monitoring before norepinephrine treatment and 1 hour thereafter blood pressure, heart rate, arterial blood gas analyses were recorded at the same time. The intravenous fluid volume and urine volume from the diagnosis of shock to the commencement of norepinephrine therapy (T0) and 24 hours thereafter (T1) were recorded, and the hemodynamic parameters, vasoactive drugs and clinical outcomes were analyzed.Results:A total of 66 newborns were enrolled, including 27 cases of mild shock, 33 cases of moderate shock and 6 cases of severe shock. 48 were male infants, 38 cases were premature infants. The gestational age was (35.2±4.1) weeks and the birth weight was (2 476±909) g. The median time of shock diagnosis was 2 days after birth, and the median shock score was 4 points. The median time from the diagnosis of shock to the start of norepinephrine treatment was 7.5 hours. Compared with that before norepinephrine treatment, stroke volume, stroke volume index, cardiac output, cardiac index, left ventricular ejection fraction, shortening fraction, systolic blood pressure, diastolic blood pressure, mean arterial pressure, blood pH and BE at 1 hour after treatment were increased, heart rate and blood lactic acid were decreased, the differences were statistically significant ( P<0.05). Urine volume was increased 24 hours after treatment ( P<0.05), and fluid overload decreased ( P<0.05). The maximum dopamine dose, the down-regulation time and duration of vasoactive drugs were positively correlated with the time to start norepinephrine therapy ( r=0.325、 r=0.383、 r=0.319, P<0.05). Among the 66 infants, 58 infants with shock had been corrected and 14 infants died within 28 days. Conclusions:Norepinephrine is effective and feasible in the treatment of neonatal septic shock and can significantly improve hemodynamic parameters.
