With wide application of 68Ga-prostate specific membrane antigen(PSMA)positron emission tomography(PET)technology in the diagnosis of prostate cancer (PCa), researchers have paid more attention to nodal staging in PCa by 68Ga-PSMA PET. Currently, 68Ga-PSMA PET has been used to detect lymph node metastases (LNMs) in primary prostate cancer patients and recurrent prostate cancer patients. Compared with the traditional imaging techniques, 68Ga-PSMA PET can detect LNMs with higher sensitivity, specificity and accuracy, which has great impact on treatment management of PCa patients. This article reviewed the research progress of detection of LNMs by 68Ga-PSMA PET in prostate cancer patients.

Objective:To evaluate the status quo and influencing factors of hyperlipidemia management in patients with contracted family doctor service in the community.Method:The baseline data and blood lipid testing results of 752 hyperlipidemia patients (334 males and 418 females) with contracted family doctor service in Yuetan Community Health Service Center from November?2019 to May 2020 were collected. The hyperlipidemic patients were managed by family doctors based on atherosclerotic cardiovascular diseases(ASCVD) riks assessment. The ASCVD risk levels and low-density lipoprotein cholesterol (LDL-C) compliance rate of patients with different general data were compared, and the influencing factors of LDL-C control failure were analyzed by logistic regression.Results:The ASCVD risk assessment showed that among 752 patients there were 172 cases of low risk(22.87%), 167 cases of moderate risk(22.21%),352 cases of high risk(46.81%) and 61 cases of extremely high risk(8.11%). A significant difference was detected in sex,rate of smoking,incidence of overweight or obesity among patients with different ASCVD risk levels ( P<0.05).The overall control rate of LDL-C was 48.8% (367/752), that for low, moderate, high and extremely high risk patients were 83.73% (144/172), 53.89% (90/167), 34.38% (121/352) and 19.67%(12/61), respectively. A significant difference was detected in sex(female: 52.87%, 221/418),age(aged over 80: 58.82%, 110/187), rate of smoking (non-smoking:52.40%, 327/624) and medication compliance (good compliance:52.87%,221/418) between LDL-C control and uncontrol groups (χ2=6.323,11.816,19.022,25.274; P<0.05). Multiple logistic regression analysis revealed that male gender ( OR=1.800,95% CI:1.325-2.419), smoking ( OR=2.630,95% CI:1.726-4.007) and poor medication compliance ( OR= 2.179, 95% CI: 1.581-3.003) were independent risk factors for uncontrolled LDL-C levels. Conclusion:Patients with hyperlipidemia have a relatively high risk of cardiovascular diseases, and their blood lipids are not well controlled. The management of blood lipid should be enhanced in patients with chronic diseases, particularly for male patients with smoking and poor medication compliance.

Objective:To investigate the psychological stress and related factors of community medical staff in Shanghai during infectious public health emergencies.Methods:Random cluster sampling, questionnaires combining general demographic information, self-rating anxiety scale(SAS), self-rating depression scale(SDS)and yale-brown obsessive compulsive scale(YB)were administrated to investigate the psychological stress of medical staff from 20 community healthcare centers in 10 Shanghai districts.Results:A total of 696 valid questionnaires were collected. 17.36% of the staff had SAS scores exceeding the boundary value. Nurses, staff with per capita monthly family income<5 000 yuan, or with below-average family relations presented higher SAS scores. 28.19% of the staff had SDS scores exceeding the boundary value. Staff with 5-10 years seniority, nurses, with per capita monthly family income<5 000 yuan, and with poor family relations presented higher SDS scores. 6.68% of the staff had YB score≥16. Nurses presented a higher YB score.Conclusions:Some community healthcare center staff experienced psychological stress during public health emergencies.Factors associated with psychological stress, such as 5-10 years′ seniority, nurses, per capita monthly family income<5 000 yuan, below-average or poor family relations, deserve more attention in order to prevent from or alleviate harmful psychological stress.

Objective:To fully understand the maternal and neonatal outcomes in pregnant women with COVID-19 and explore the evidence of intrauterine vertical transmission of 2019-nCoV by analyzing clinical and laboratory information in peer-reviewed publications on COVID-19 in pregnant women.Methods:PubMed, Embase, China National Knowledge Infrastructure, China Academic Journals, and Wanfang Databases were searched to retrieve articles on COVID-19 in pregnancy published from December 1, 2019, to April 9, 2020. In addition, the World Health Organization COVID-19 Database and the reference lists in each included article were also searched. All included cases were positive for 2019-nCoV nucleic acid with maternal and neonatal outcomes regardless of delivery or not. Clinical manifestations, perinatal and neonatal outcomes were analyzed systematically.Results:This study reviewed 29 publications involving 146 pregnant women who tested positive for 2019-nCoV nucleic acid and their 116 newborns (including two twins). Five cases of severe COVID-19 and three cases of unidentified type that were admitted to ICU for treatment were severe symptoms, accounting for 5.5% (8/146) of all cases. Totally, 69.9% (102/146) of the women underwent cesarean section and 8.2% (12/146) gave birth vaginally. Thirty (20.5%) women continued their pregnancies. One case (0.7%, 1/146) terminated the pregnancy at 26 weeks of gestation due to bidirectional affective disorder and one (0.7%, 1/146) received artificial abortion at 6 weeks of gestation. Fever (58.2%, 85/146) and cough (32.9%, 48/146) were the most common symptoms. However, 15.8% (23/146) of the pregnant women were asymptomatic on admission and symptoms appeared or became worse after delivery in 20.5% (30/146). Lymphocytopenia (49.6%, 56/113) and elevated C-reactive protein (58.4%, 66/113) were the main laboratory findings. The most common computed tomography (CT) finding was bilateral multiple patchy ground-glass opacity in lungs (79.7%, 94/118). The outcomes of 92.2% (107/116) of the newborns were good, and the rest 7.8% (9/116) showed different abnormalities of varying degrees. Among the nine newborns, six showed different degrees of dyspnea, cyanosis and vomiting including one died of multiple organ failure and disseminated intravascular coagulation; one tested positive for viral nucleic acid 36 hours after birth; one was stillbirth due to unknown reason, but intrauterine vertical transmission was excluded; one neonatal death in a critically ill mother undergoing cesarean delivery.Conclusions:Pregnant women are less likely to progress to severe COVID-19 and mostly have a good outcome. Despite reports of adverse neonatal outcomes, evidence of intrauterine vertical transmission of 2019-nCoV remains insufficient.

Objective: To survey on the home blood pressure measurement and blood pressure control rate among patients with hypertension in Beijing Yuetan community. Methods: A questionnaire survey was conducted among 504 hypertensive patients, who were visiting Beijing Yuetan Community Health Service Center and selected by convenience-sampling method during June 2018 to January 2019. The status of home blood pressure measurement, the awareness of hypertension, the blood pressure control rate and factors related to not regularly measuring were surveyed. Results: Of the 504 patients, 93.7% (472/504) took regular medication, but only 61.5% (310/504) had regular blood pressure measurements; 92.5% (466/504) had sphygmomanometers at home with electronic type mainly; 89.9% (453/504) patients knew the method of blood pressure measurement, but only 11.5% (52/453) had their sphygmomanometer calibrated. Among those who measured blood pressure, 77.4% (240/310) measured per week. The main reason for not measuring blood pressure regularly was that there was no need to measure blood pressure without any discomfort, accounting for 50.0% (97/194). The office blood pressure control rate (with desktop mercury sphygmomanometer) was 62.3% (314/504); the blood pressure control rate both in the morning and at bed time was 61.3% (73/119), that in the morning was 68.1% (81/119) and at bed time was 75.6% (90/119). The control rates of systolic blood pressure and heart rate by home measurement at morning and bedtime were significantly higher than those by office measurement (χ²=5.02, 9.97, 15.51, 13.72; all P<0.05). Conclusions The home blood pressure monitoring rate and knowledge level of hypertension among patients with hypertension in Yuetan community are relatively low. There are some differences in blood pressure control rate between office measurement and home measurement. Comprehensive evaluation is needed in the management process, and the treatment plan should be adjusted according to the specific condition of patients.

Aim To investigate the effects of starfish saponins(Sfs) on insulin signaling pathway in orotic acid-induced NAFLD rats.Methods 1% orotic acid was used to establish NAFLD model in male Wistar rats for six weeks.The NAFLD rats were randomly divided into two groups(eight rats in each group) and then fed with the corresponding diets: Model group(1% orotic acid)and Sfs group(1% orotic acid containing 0.04% starfish saponins).After starfish saponins feeding for 8 weeks, hepatic lipids content, liver function indices and relevant protein expression in muscle insulin signaling pathway were measured.Results Compared with model group, starfish saponins reduced hepatic lipids content and improved liver functions.In addition, it effectively ameliorated insulin resistance by improving insulin signaling pathway and improved glucose uptake in muscle.Conclusion The amelioration effect of starfish saponins on impaired insulin signaling pathway in muscle is observed in orotic acid-induced NAFLD rats.

Aim To investigate the effects of saponin of sea cucumber ( SSC ) on the blood pressure in obese mice. Methods C57BL/KsJ(db/db) mice were ran-domized into 3 groups ( 8 mice each ): model group, low-dose SSC group and high-dose SSC group. Normal C57BL/KsJ mice were used as control. The low and high SSC groups were fed on basal diets incorporated with 0. 02% and 0. 04% SSC. Different treatments were administered for 6 weeks and arterial pressure was measured in the third and sixth weeks. The abundance of renal ACE, ACE2 and REN mRNA was detected by real time PCR . Results Compared with control group, the blood pressure of model group mice was ob-viously raised ( P<0. 01 ) . Low-dose SSC group mice showed lower blood pressure than model group without statistically significant differences, and the blood pres-sure of high-dose SSC group mice was similar to that of control group and significantly lower than model group. ( P<0. 05 ) There were no remarkable differences a-bout ACE and REN mRNA among the groups, howev-er, ACE2 mRNA level was significantly increased in high-dose SSC group. Conclusion SSC plays a vital role in decreasing blood pressure, which probably re-lates to the regulating function of renin-angiotensin sys-tem( RAS) .

Objective To study the sleep improvement function of DHA-PC.Methods The mice were randomly divid-ed into control, vehicle, DHA+Lecithin (60+200 mg/kg) and DHA-PC(50,100,200 mg/kg) groups.Ten mice were enrolled in each group .The mice of control were administered with normal food , the vehicle group was orally given normal saline at the dosage of 0.2 ml/10 g, while both DHA-PC and DHA+Lecithin were orally given corresponding drugs at the dosage of 0.2 ml/10 g.All the groups were treated for 30 days except control group .The direct sleep-inducing test, the test of lengthening sleep time induced by pentobarbital sodium , the test of pentobarbital sodium subthreshold-hypnosis and the test of barbital sodium sleep latency were conducted to observe the inductive effect of DHA -PC.Results Neither the effect on mice body mass nor directly-induced sleep was observed .DHA-PC (50,100, and 200 mg/kg) could prolong sleep time to (56.2 ±13.7),(57.9 ±25.4) and(64.1 ±18.4) min, respectively,compared to vehicle(32.9 ±10.8)min (P<0.05).DHA+Lecithin could not prolong sleep time (38.6 ±11.7)min compared to (32.9 ±10.8)min of vehicle.There was significant difference compared with DHA-PC at the dosage of 200 mg/kg (64.1 ±18.4)min (P<0.05).DHA-PC (200 mg/kg) enhanced pentobarbital sodium subthreshold-hypnosis (70%) compared to vehicle (10%) (P<0.05),so did DHA+Lecithin (60%) compared to vehicle (10%) (P<0.05).Both DHA-PC (200 mg/kg)[(22.9 ±4.1)min ] and DHA+Lecithin [(19.5 ±2.7) min ]could shorten sleep latency compared to vehicle (31.3 ±6.9) min(P<0.01), and the sleep latency of DHA +Lecithin (19.5 ±2.7) min was shorter than that of DHA-PC(50,100 mg/kg).Conclusion DHA-PC has some effect some sleep improvement in mice .

Objective To investigate the effects of recombinant human fibronectin fragment (RetroNectin) combined with anti-CD3 monoclonal antibody (CD3Ab) on the proliferation and cytotoxicity of cytokine-induced killer cells (CIK) from acute leukemia (AL). Methods Mononuclear cells (MNCs) were isolated from peripheral blood of complete remission AL pa-tients. The MNCs were cultured in vitro by precoating with RetroNectin (RN group), CD3Ab (CD3Ab group), RetroNectin com-bined with CD3Ab (RN+CD3Ab group) and traditional method (control group) to generate CIK. The changes of growth rate, characterization, cytotoxicity and apoptosis of CIK were determined between groups. Results The amplification of CIK was higher in experimental group than that of control group, and the amplification of CIK was higher in group RN+CD3Ab than that of in group RN and group CD3Ab (P＜0.05). The expression of CD25 positive cells was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P＜0.05).The percentage of G1 stage cells was lower in group RN and group RN+CD3Ab than that of group CD3Ab and control group. The percentage of S stage cells was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P＜0.05). The cytotoxicity was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P＜0.05) at the E/T scope 40∶1.The percentage of apoptotic cells was lower in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P ＜ 0.05). Conclusion These in vitro studies suggest that a higher activity of immune cells could be obtained by CIK cells cultured by precoating Ret-roNectin and CD3Ab.
