ABSTRACT
ObjectiveTo investigate the satisfaction of both service providers and users in community health service centers through questionnaires， and to analyze the reasons， so as to put forward suggestions for improving satisfaction. MethodsSampling was conducted in 247 community health service centers in 16 districts of Shanghai， and data were collected from employees and patients through on-site questionnaires. ResultsA total of 10 334 eligible questionnaires were collected from community health service centers， of which 7 712 were from patients and 2 622 were from employees. In 2021， the public's satisfaction with community health service centers was 96.51 points， and the satisfaction of employees was 94.08 points. The public expressed lower satisfaction with the availability of essential drugs for outpatient services， while the staff were less satisfied with their salary and benefits， work recognition， and career development. Regarding family doctor services， 73.38% of the public had signed up for family doctor services， while 23.57% of the public did not know about the family doctor services， and 16.18% believed it was necessary to improve the publicity of basic public health services. ConclusionThe public's overall satisfaction with the service of community health services is gradually increased. The basic medical services of community health are recognized by residents. Drug allocation needs to be improved urgently， and publicity and promotion need to be further strengthened. The overall satisfaction of employees is high， but further improvement is needed in terms of salary and benefits， work recognition， and career development.
ABSTRACT
OBJECTIVE To compare the phar macokinetics o f ligustrazine hydrochlori de，salvianic acid and rosemarinic acid from Shenxiong glucose injection （SGI）in normal and acute myocardial ischemia （AMI）rats. METHODS Male SD rats were randomly divided into normal group and model group ，with 9 rats in each group. AMI model was established by isoproterenol hydrochloride modeling method. Three rats in each group were selected for model verification. The remaining 6 rats in each group were given SGI （1.2 mL/kg）or equal volum of normal saline via tail vein ；0.3 mL blood was collected through orbital venous bush 0.083，0.167，0.333，0.5，0.75，1，1.5，2，3，5 h after administration. Using luteoloside as internal standard ，the plasma concentrations of ligustrazine hydrochloride ，salvianic acid and rosemarinic acid were determined by ultra performance liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were fitted by WinNonlin 8.1 software，and statistical analysis was performed by SPSS 18.0 software. RESULTS The linear ranges of ligustrazine hydrochloride ，salvianic acid and rosmarinic acid were 0.06-29.96，0.01-5.15 and 0.006-3.09 μ g/mL（all r＞0.99），respectively. The results of methodological investigation were all in line with the requirements of Chinese Pharmacopoeia （2020 edition）. Compared with normal rats ，CLz of ligustrazine hydrochloride in AMI model rats was significantly increased （P＜0.05）；t1/2 and Vz of salvianic acid were significantly prolonged or increased （P＜0.05）；but the cmax and AUC 0－5 h were significantly decreased （P＜0.05）；AUC0－5 h of rosmarinic acid was significantly decreased （P＜0.05）. CONCLUSIONS The exposure levels of salvianic acid and rosmarinic acid in SGI are lower in AMI model rats than in normal rats ，and the elimination of ligustrazine hydrochloride in AMI model rats is stronger than that in normal rats.
ABSTRACT
Objective:To investigate the relationship of the acute radiation reactions of totalbody irradiation before hematopoietic stem cell transplantation with the different total and fractionated doses of irradiation.Methods:The clinical data of 48 patients who underwent 6 MV X-ray total body irradiation pretreatment from May 2015 to December 2019 in Shijiazhuang Ping'an Hospital before undergoing hematopoietic stem cell transplantation were retrospectively analyzed. The patients were divided into 8 Gy group (12 cases), 10 Gy group (31 cases) and 12 Gy group (5 cases) according to the total radiation dose, and divided into 4 Gy/f group (17 cases) and 5 Gy/f group (31 cases) according to the fractionated radiation dose. Acute radiation reactions in the oral mucosa, pharynx, salivary glands, upper gastrointestinal tract, lower gastrointestinal tract and lung of patients in each group after radiotherapy were summarized and compared.Results:Acute pharyngeal reaction in the total radiation dose of 8 Gy group showed that 11 cases (91.7%) were grade 0 and 1 case (8.3%) was grade 1; in the total radiation dose of 10 Gy group, 10 cases (32.3%) were grade 0, 13 cases (41.9%) were grade 1, 4 cases (12.9%) were grade 2, 3 cases (9.7%) were grade 3, and 1 case (3.2%) was grade 4; in the total radiation dose of 12 Gy group, 2 cases (40.0%) were grade 0, 1 case (20.0%) was grade 1, 1 case (20.0%) was grade 2, and 1 case (20.0%) was grade 3. The severity of acute pharyngeal radiation reaction in the total radiation dose of 8 Gy group was better than that in the 10 Gy and 12 Gy groups, and the difference was statistically significant ( χ2 = 11.338, P = 0.003); there was no significant difference in the incidence of acute radiation reactions in other parts (all P > 0.05). Acute pharyngeal radiation reaction in the fractionated radiation dose of 4 Gy/f group showed that 13 cases (76.5%) were grade 0, 2 case (11.8%) was grade 1, 1 case (5.9%) was grade 2, and 1 case (5.9%) was grade 3; in the 5 Gy/f group, 10 cases (32.3%) were grade 0, 13 cases (41.9%) were grade 1, 4 cases (12.9%) were grade 2, 3 cases (9.7%) were grade 3, and 1 case (3.2%) was grade 4. The severity of acute pharyngeal radiation reaction in the fractionated radiation dose 4 Gy/f group was better than that in the 5 Gy/f group, and the difference was statistically significant ( Z = -2.606, P = 0.009); there was no significant difference in the incidence of acute radiation reactions in other parts (all P > 0.05). Conclusion:The total dose of 8 Gy and fractionated dose of 4 Gy/f in the total body irradiation before hematopoietic stem cell transplantation can alleviate the acute pharyngeal radiation reaction.
ABSTRACT
Objective: To evaluate factors that affect recurrence ofⅠb-Ⅱa cervical cancer after surgery or radiation therapy, and to provide evidence for prevention and personalized treatment of cervical cancer recurrence. Methods: We retrospectively analyzed clini-cal and pathological data of 193 patients with stageⅠb-Ⅱa cervical cancer who were diagnosed and treated in Affiliated Cancer Hos-pital of Xinjiang Medical University from January 2010 to April 2015. The patients were assigned into the following two groups: postop-erative radiotherapy recurrence group (36 cases) and non-recurrence group (157 cases). Factors related to recurrence after postopera-tive radiotherapy were analyzed. Results: The incidence rates of squamous cell carcinoma, adenocarcinoma, and other cervical cancer types were 90.2% (174/193), 5.7% (11/193), and 4.1% (8/193), respectively. The recurrence rates of squamous cell carcinoma, adeno-carcinoma, and other cervical cancer types were 16.7% (29/174), 45.5% (5/11), and 25.0% (2/8), respectively. The difference was statis-tically significant (χ2=12.463, P<0.05). The proportion of patients with age≤40 years, adenocarcinoma, vaginal margin, vascular inva-sion, lymph node metastasis, and parametrial invasion was higher in the relapse group than in the non-relapse group; the difference was statistically significant between the two groups (P<0.05). The odds ratio (OR) values for positive vaginal margin, positive vascular invasion, and positive parametrial invasion were above 1 (P<0.05). Therefore, these three factors were independent risk factors for cer-vical cancer recurrence after radiotherapy. Conclusions: Among stage Ib-IIa cervical cancer cases, squamous cell carcinoma had the highest recurrent incidence. However, the rate of recurrence after surgery or radiation therapy was the highest for adenocarcinoma. Postoperative pathology suggests that patients with positive vaginal margins, positive vascular infiltration, and positive parametrial in-vasion have a high risk of recurrence after radiotherapy and should be followed-up carefully.
ABSTRACT
Objective:To explore the factors affecting the postoperative prognosis of early cervical squamous cell carcinoma and inves-tigate the different radiotherapy techniques. Methods:A total of 100 postoperative patients of early cervical squamous cell carcinoma treated in Affiliated Tumor Hospital of Xinjiang Medical University and Affiliated Tumor Hospital of Sun Yat-sen University from March to September 2013 were enrolled in our study. The prognostic factors for these patients were analyzed. After being subjected to differ-ent postoperative radiotherapy techniques, the efficacy and complications of the techniques were assessed for patients, including 50 cases of conventional radiotherapy (CRT) and 50 cases of image-guided radiotherapy (IGRT). Results:The 3-year overall survival rate was 89%, and the 3-year disease-free survival rate was 78%. The 3-year overall survival rates of the CRT and IGRT groups were 78.57%and 89.06%, respectively. The difference between these rates was statistically significant (P=0.034). The 3-year survival rates of the CRT and IGRT groups were 66.67%and 87.36%, respectively. The difference was statistically significant (P=0.042). The incidence of ear-ly and late complications in the CRT group was higher than that in IGRT group, and the difference of P<0.05 was statistically significant. Multivariate analysis showed that postoperative radiotherapy, parametrial invasion, lymph node metastasis, lymphovascular space in-vasion, perineural invasion, and deep stromal invasion were the independent risk factors for the prognosis of patients with early stage cervical squamous cell carcinoma. Conclusion:Early prognosis of cervical squamous cell carcinoma results from the interaction of mul-tiple factors. The 3-year survival rate of the IGRT group was significantly better than that of the CRT group in the early stage of cervical squamous cell carcinoma. IGRT alleviates acute and chronic toxicities and helps improve the quality of life of patients.
ABSTRACT
Polyacrylic acid was firstly grafted by N-amino-4-N-methylpiperazine-1,8-naphthlimide (AMN) to prepare a amphiphilic polymer, which was self-assembled in water producing nanoparticles called as PAAMN.Then the morphology, structure and fluorescence properties of PAAMN were investigated by various methods including transmission electron microscopy, dynamic light scattering, ultraviolet-visible spectroscopy (UV-Vis), nuclear magnetic resonance spectroscopy (HNMR) and fluorescence spectroscopy.MTT assay was carried out to assess the cell compatibility of PAAMN.Finally, the fluorescence from PAAMN self and HeLa cells incubated with PAAMN was observed by fluorescence microscope.The results revealed that PAAMN had spherical structure, in which naphthlimide fluorphores were immobilized in the polyacrylic acid matrix with the degree of substitution of 4.1%.Under the physiological pH condition, PAAMN excited at 390 nm could emit strong and stable fluorescence at 534 nm.In the range of pH 4.0-10.0, its excitation and emission wavelengths had no obvious change.The fluorescence intensity of PAAMN increased with the decrease of pH values, but the pH sensitivity of PAAMN was much lower than that of AMN.PAAMN had good cell compatibility.From the pictures of fluorescence imaging, it was found that both PAAMN self and cells-engulfed PAAMN could emit green fluorescence upon excited at 390 nm, indicating the potential of the developed nanoparticle for cell imaging.
ABSTRACT
Objective To determine the value of complexed prostate-specific antigen (cPSA) in predicting metastasis in patients with prostate cancer.Methods From January 2012 to April 2014,the clinical data of 74 patients with newly diagnosed prostate cancer in our hospital was retrospective reviewed.The prostate cancer was diagnosed by transrectal ultrasound guided biopsy and postoperative pathologic diagnosis.The patients were divided to 2 groups according to metastases status.There were 38 patients in the group of metastasis and 36 patients in the group of without metastasis.In metastasis group,the bone metastasis was found in 36 cases.There is only one case with lung metastasis and one case with lymph node metastasis.In the group without metastasis,the T stages classification were T1-T2 in 17 cases and T3-T4 in 19 cases.While,10 cases with T1-T2 stage and 28 cases with T3-T4 stage were confirmed in the group with metastasis.There was no statistical significance of T stages and mean age in two groups (P＞0.05).The level of cPSA in the serum was detected by chemiluminescent immunoassay,the level of tPSA,fPSA were detected by electro-chemiluminescent immunoassay,fPSA/tPSA,cPSA/tPSA were evaluated and the corresponding specificity were calculated.The correlation of age with tPSA,cPSA were analysed.The differences in PSA,fPSA/tPSA,cPSA/tPSA were compared between metastasis and non-metastasis group.ROC curve analysis was used to determine the diagnostic value of cPSA and tPSA,In the meantime,area of ROC curves were compared by Z test.Results The age was not related to the value of tPSA (r=-0.09,P=0.12) and cPSA(r=-0.38,P=0.14).The median levels of tPSA,fPSA,and cPSA are 29.88μg/L,2.18 μg/L and 18.86 μg/L in the group without metastasis,respectively.The median levels of tPSA,fPSA,and cPSA were 410.05 μg/L,51.50 μ.g/L and 290.40 μg/L in the group with metastasis,respectively.Significant differences of those results could be found in two groups (P＜0.05).fPSA/tPSA was 0.07 and cPSA/tPSA was 0.79 in the group without metastasis.fPSA/tPSA was 0.08 and cPSA/tPSA was 0.80 in the group of metastasis.fPSA/tPSA (P=0.77),cPSA/tPSA (P=0.64) in patients with metastasis were not greater than in those without metastasis (P＞0.05).The area under the curve of tPSA and cPSA were 0.83 (95％ CI 0.73-0.93) and 0.82 (95％CI 0.73-0.92) respectively.Analysis of ROC curves showed that the AUC for cPSA is not significant different from tPSA (Z=1.64,P=0.10).The specificity of cPSA was 22.2％ which is higher than that of tPSA (19.4％) at a sensitivity of 92.1％ in predicting metastasis comparing with the patients without metastasis.The sensitivity could reach to 90.0％ when the cut off value of tPSA was 9μg/L or the cut off value of cPSA was 7 μg/L.Conclusions In our study,a preliminary validation that cPSA is useful for predicting the metastasis in patients with prostate cancer was made.
