ABSTRACT
OBJECTIVE To investigate the current situation of pharmaceutical management in compact medical consortium of Guangdong province, and to provide decision-making basis for promoting the high-quality construction and sustainable development of the provincial medical consortium. METHODS A self-designed questionnaire was used to select 50 compact medical consortiums in Guangdong province. The survey was answered by the heads of the pharmacy department of the general hospitals. The survey covered the basic scale of the consortium, the appointment of chief pharmacists, the implementation of pharmaceutical management and pharmaceutical care homogenization within the consortium, the difficulties in promoting the homogenization, and the expected provincial support. Descriptive statistical analysis was performed on the survey results. RESULTS A total of 50 questionnaires were collected, and the effective recovery rate was 100%. There were 16 chief pharmacists (32.00%) in charge of the pharmacy department of the general hospital in the medical consortium. Thirty-seven medical consortiums (74.00%) had established a drug supply support system within the consortium, 35 medical consortiums (70.00%) had carried out pharmaceutical management and coordination work within the medical consortium, 23 medical consortiums (46.00%) had established a clinical medication guidance system, 25 medical consortiums chenwenying2016@163.com (50.00%) had established a bidirectional communication mechanism, and only 8 medical consortiums (16.00%) had developed new models of pharmaceutical care. At present, the difficulties in promoting the homogenization of pharmaceutical management and pharmaceutical care within the medical consortium were mainly found in three aspects: the wide gap in management level of each member unit, the lack and uneven level of pharmaceutical personnel, and insufficient policy support and implementation. Most medical consortiums hoped that relevant departments could promote the homogenization of pharmaceutical work by holding special training courses or special supervision. CONCLUSIONS At present, the compact medical consortium in Guangdong province has achieved initial results in the implementation of the chief pharmacist system, the homogenization of pharmaceutical management and pharmaceutical care. However, it is still necessary to improve the coverage of chief pharmacist appointments in the medical consortium, implement the homogenization of pharmaceutical management, and accelerate the homogenization process of pharmaceutical care.
ABSTRACT
Objective:To analyze the current situation and influencing factors of rectus abdominis muscle separation in postpartum women.Methods:The clinical data of 3 368 postpartum women who underwent postpartum physical examination in Shenzhen Longgang maternal and child health hospital from June to October 2020 were retrospectively analyzed. The general data, rectus abdominis separation and pelvic organ prolapse were collected for cross-sectional investigation.Results:The incidence of rectus abdominis separation in postpartum women was 60.7% (2 045/3 368). <30 years old, ≥30 years old (56.8% (856/1 507) and 63.9% (1 189/1 861), χ2=17.54)). The increase of body mass during pregnancy was <16 kg, ≥16 kg (59.1% (1 351/2 285) and 64.1% (694/1 083), χ2=7.57)). Spontaneous labor and cesarean section (55.7% (1 262/2 266) and 71.7% (790/1 102), χ2=77.87)). Pregnancy 1, 2, ≥3 times (53.9% (645/1 196), 62.1% (702/1 131) and 67.1% (698/1 041), χ2=41.48). Production for 1, 2, ≥3 times (53.9% (877/1 628), 67.0% (1 016/1 517) and 68.2% (151/223), χ2=62.09)). History of macrosomia (68.7% (160/233) and 60.1% (1 885/3 135), χ2=6.64)). Prolapse of anterior vaginal wall (75.2% (1 559/2 072) and 37.5% (486/1 296), χ2=476.15), there were significant differences in the incidence of rectus abdominis separation (all P<0.05). Logistic regression analysis showed that ≥ 3 times pregnancies ( OR=1.572,95% CI=1.270-1.945),cesarean section ( OR=2.440,95% CI=2.050-2.905),macrosomia ( OR=1.660,95% CI=1.213-2.273), anterior vaginal prolapse( OR=7.324,95% CI=6.083-8.819) were risk factors of diastasis recti abdominis (all P<0.05). Conclusions:The incidence of rectus abdominis separation in postpartum women is high. Three or more pregnancies, cesarean section, history of macrosomia and prolapse of anterior vaginal wall play an important role in the occurrence of rectus abdominis separation.
ABSTRACT
Objective:To analyze the body composition and determinants of gestational diabetes mellitus(GDM), so that to provide basic data for prevent and control GDM further.Methods:All 1 553 pregnant women with GDM (GDM group) at 24-28 weeks of gestation were selected, and 1 298 pregnant women with normal glucose tolerance (NGT) at the same pregnancy were taken as the control group. The general data, body composition test data and 75 g oral glucose tolerance test results of the two groups were collected for statistical analysis. T-test was used for comparison between normal distribution measurement data groups, and counting data were compared χ 2 inspection.

The low, normal and high water content in GDM group were 36.3%(564/1 553), 54.3%(843/1 553), 9.4%(146/1 553), and 22.5%(292/1 298), 58.8%(763/1 298), 18.7%(243/1 298), respectively. There were statistically significant differences in the overall distribution of body mass index before pregnancy and the contents of body water, body fat and protein between the two groups (statistical values were 78.89, 100.21, 43.80 and 92.54, all P<0.001). Logistic analysis showed that old age ( OR=3.462, 95% CI=2.737-4.380), overweight before pregnancy ( OR=1.296, 95% CI=1.031-1.628), family history of diabetes ( OR=2.061, 95% CI=1.676-2.535), history of GDM ( OR=12.688, 95% CI=4.577-35.169), high body fat content ( OR=1.607, 95% CI=1.234-2.092), low water content ( OR=1.493, 95% CI=1.025-2.175) were the risk factors of GDM (all P<0.05). Low body fat content ( OR=0.341, 95% CI=0.151-0.768) was the protective factor of GDM ( P<0.05). Conclusions:In addition to the traditional risk factors such as body mass index before pregnancy, old age, family history of diabetes, and history of GDM, the contents of body water and body fat also played an important role in the occurrence of GDM.
ABSTRACT
OBJECTIVE To exc avate the adverse drug event (ADE)signals of semaglutide and provide reference for its clinical rational use. METHODS The proportional unbalance method was used to mine the signals of all semaglutide ADE reports from FDA Adverse Event Reporting System (FAERS)up to September 2021. The basic situations of the reported cases were analyzed. The corresponding system organ classification (SOC)was mapped and compared with the adverse drug reactions recorded in the drug instructions. Preferred terms (PT)of patients with different indications were analyzed. RESULTS A total of 6 661 semaglutide ADE reports were extracted and 194 valid signals were mined. Among 6 661 cases of ADE ,the proportion of men (43.40%)was lower than women (52.65%);the age was mainly distributed in >40-65 years old (29.00%)and >65 years old (22.61%);the reporting country was mainly the United States (83.88%);the report year was mainly concentrated in 2021 (40.88%),with an increasing trend year by year ;the main outcome was hospitalization or prolonged hospitalization in serious ADE reports (17.78%). Semaglutide ADE signal was mapped to the main SOC ,mainly including gastrointestinal diseases ,various injuries,poisoning and operation complications ,metabolic and nutritional diseases ,various examinations. The screening criteria were based on the report odds ratio >10 or ADE reported cases >50,and 48 new potential adverse drug reactions were added to the drug description. Among the indications with the top two reported cases (type 2 diabetes and obesity ,overweight,weight control),the frequency of gastrointestinal system related ADE reports represented by nausea ,vomiting and diarrhea was higher , which was similar to the drug instructions. CONCLUSIONS This study supplemented 48 new potential adverse drug reactions based on the drug instructions of semaglutide. At present ,it can be considered that semaglutide is safe.

ABSTRACT
Objective:To evaluate the value of ultrasound-guided transperineal systematic prostate biopsy(SPB)and cognitive fusion multi-parameter magnetic resonance imaging(mpMRI) suspicious transperineal targeted biopsy(CFTB) in the prostate cancer with different serum prostate specific antigen(PSA) levels.Methods:A retrospective analyses were performed in 527 patients with suspected prostate cancer who underwent ultrasound-guided SPB from January 2018 to December 2019 in Shanghai Jiaotong University Affiliated 6th People′s Hospital. According to the PSA levels, they were divided into group A(PSA 4-10 μg/L) and group B(PSA>10 μg/L). All the patients underwent ultrasound-guided SPB, 376 patients with suspicious mpMRI had two additional targeted biopsies. The detection rates of ultrasound-guided SPB and CFTB in prostate cancer were tested by χ 2 test. Compared with pathological results, the sensitivity, specificity, accuracy of two methods were calculated and tested by χ 2 test, and a P<0.05 was defined as statistically significant difference. Results:Prostate cancer was detected in 319 of 527 patients(60.5%). One hundred and three cases of 198 patients in group A were diagnosed as prostate cancer, with an overall detection rate was 52.0%. Among them, ultrasound-guided SPB detected 72 cases of prostate cancer, the detection rate was 36.4%, sensitivity was 67.9%, specificity was 17.7%, accuracy was 26.5%, the detection rate, sensitivity, specificity and accuracy of CFTB were 39.9%, 75.6%, 91.6% and 88.8%, respectively. In this group, there were no statistically significant differences in the detection rate and sensitivity of the two methods in the diagnosis of prostate cancer (χ 2=0.525, 0.005, both P>0.05), and the differences in specificity and accuracy were statistically significant (χ 2=108.340, 79.829, respectively, both P<0.05). Two hundred and sixteen cases of 329 patients in group B were diagnosed as prostate cancer, with an overall detection rate was 65.7%. Among them, 160 cases of perineal prostate cancer were detected by ultrasound-guided SPB, with the detection rate was 48.6%, sensitivity was 78.2%, specificity was 37.6% and accuracy was 49.5%. A total of 189 cases of prostate cancer detected by CFTB, the detection rate was 57.4%, the sensitivity was 89.3%, the specificity was 90.6%, and the accuracy was 90.2%. All the differences were statistically significant in group B(χ 2=5.131, 4.391, 61.339, 38.982, all P<0.05). Conclusions:When PSA is greater than 10 μg/L, CFTB has a higher diagnostic efficiency than SPB.When PSA is 4-10 μg/L, there are no significant differences between the two methods in the detection rate and sensitivity of prostate cancer.

ABSTRACT
Background:Recent studies have shown that long non-coding RNAs(lncRNAs)play important roles in carcinogenesis and cancer biology and the related context has attracted more and more attentions. PVT1,which encodes a lncRNA,is reported to be up-regulated and exhibit pro-oncogenic activity in a wide variety of human cancers. Aims:To investigate the expression of PVT1 in human pancreatic cancer cells and its effect on proliferation and apoptosis of HPAF-Ⅱ cells. Methods:One target siRNA against PVT1 was synthesized and transfected into HPAF-Ⅱ cells by using lipofactamine technique. PVT1 mRNA expression was detected by real-time PCR;capability of cell proliferation was examined by MTS and colony formation assays;cell cycle progression and apoptosis were measured by flow cytometry;and Western blotting was performed to determine the expressions of apoptosis-related proteins and proto-oncogene protein c-Myc. Results:The mRNA expression of PVT1 in several human pancreatic cancer cell lines,especially HPAF-Ⅱ cells was significantly higher than that in H6c7,a human immortalization normal pancreatic ductal epithelial cell line. Compared with HPAF-Ⅱ cells transfected with negative control siRNA or without transfection,silencing of PVT1 by siRNA-PVT1 resulted in remarkable reduction in cell proliferation,cell cycle G1 phase arrest,and notable apoptosis;meanwhile,the expressions of apoptosis-related proteins(cleaved-caspase-3 and cleaved-PARP)were up-regulated,the ratio for Bcl-2 / Bax was decreased,and the expression of c-Myc protein was down-regulated. Conclusions:LncRNA-PVT1 is highly expressed in human pancreatic cancer cell line HPAF-Ⅱ. It may affect the proliferation and apoptosis of HPAF-Ⅱ cells partially through regulating c-Myc expression.
ABSTRACT
OBJECTIVE:To provide reference for further formulation of the rational use of vancomycin. METHODS:Retro-spective analysis was conducted on the related information of discharged patients who intravenously used vancomycin from Jun. 2013 to Dec. 2014. RESULTS:178 patients were enrolled,with average age of 59.6 and 73.60% male,who were mainly with lung infectious(74.72%). Support examinations were sufficient before using of vancomycin. 66.29% patients were empirically giv-en vancomycin with pathogenic detection rate of 85.39%. 71.91% patients were conducted therapeutic drug monitoring with only 47.54% of first blood samples achieved the target range. CONCLUSIONS:Vancomycin application is generally rational in our hos-pital. However,issues like duration of empirical therapy,rational therapeutic monitoring,and individualized start dosing still need to be noticed.
ABSTRACT
Objective To explore the value of contrast-enhanced ultrasound(CEUS) in the evaluation of the renal cortical perfusion in rabbits in low temperature conditions.Methods 20 New Zealand rabbits were randomly divided into five groups,4 rabbits in each group:1) with the first group as the control group (under the conditions of room temperature) ; 2)The second group was treated under-15℃--23℃ for 8hours; 3)the third group was treated under-15℃--23℃ for 4 hours; 4)the fourth group was treated under-6℃--14℃ for 8 hours; 5) the fifth group was treated under-6℃--14℃ for 4 hours.SonoVue was injected via the ear vein at a dose of 0.1 ml/kg,the renal perfusion imaging was made,observing the dynamic image of 0-3 min after the injection and analyzing the time-intensity curves(TIC)obtained from the following parameters:the slope rate of ascending curve(A),the slope rate of descending curve(α),area under the curve (AUC),time to peak (TTP),and derived peak intensity(DPI).Results Compared with the control group,the A,α of the second and the fourth group were significantly decreased (P < 0.05),while the AUC was significantly increased (P < 0.05) and the TTP was significantly prolonged(P <0.05),for the third and the fifth group,only the A was decreased (P <0.05),and the DPI in each group showed no significant difference.Compared with the third and the fourth group,the AUC of the second group was increased and the TTP was prolonged (P <0.05).Conclusions Contrast-enhanced ultrasound can reflect the earlier renal cortical hemodynamic changes in rabbits in the low-temperature conditions,and is of great value for the early diagnosis of renal damage caused by low temperature.
ABSTRACT
In order to successfully develop the effective population pharmacokinetic model to predict the concentration of propofol administrated intravenously, the data including the concentrations across both distribution and elimination phases from five hospitals were analyzed using nonlinear mixed effect model (NONMEM). Three-compartment pharmacokinetic model was applied while the exponential model was used to describe the inter-individual variability and constant coefficient model to the intra-individual variability, accordingly. Covariate effect including the body weight on the parameter CL, V1, Q2, V2, Q3 and V3 were investigated. The performance of final model was assessed by Bootstrapping, goodness-of-fit and visual predictive checking (VPC). The context-sensitive half-times and the infusion rates necessary to maintain the concentration of 1 microg x mL(-1) were simulated to six subpopulations. The results were as follows: the typical value of CL, V1, Q2, V2, Q3 and V3 were 0.965 x (1 + 0.401 x VESS) x (BW/59)(0.578) L x min(-1), 13.4 x (AGE/45)(-0.317) L, 0.659 x (1 + GENDER x 0.385) L x min(-1), 28.8 L, 0.575 x (1 + GENDER x 0.367) x (1 - 0.369 x VESS) L x min(-1) and 196 L respectively. Coefficients of the inter-individual variability of CL, V1, Q2, V2, Q3 and V3 were 29.2%, 46.9%, 35.2%, 40.4%, 67.0% and 49.9% respectively, and the coefficients of residual variability were 24.7%, 16.1% and 22.5%, the final model indicated a positive influence of a body weight on CL, and also that a negative correlation of age with V1. Q2 and Q3 in males were higher than those in females at 38.5% and 36.7%. The CL and Q3 were 40.1% increased and 36.9% decreased in arterial samples compared to those in venous samples. The determination coefficient of observations (DV)-individual predicted value (IPRED) by the final model was 0.91 which could predict the propofol concentration fairly well. The stability and the predictive performance were accepted by Bootstrapping, the goodness-of-fit and VPC. The context-sensitive half-times and infusion rates necessary to maintain the concentration of 1 microg x mL(-1) were different obviously among the 6 sub-populations obviously. The three-compartment model with first-order elimination could describe the pharmacokinetics of propofol fairly well. The involved fixed effects are age, body weight, gender and sampling site. The simulations in 6 subpopulations were available in clinical anesthesia. The propofol anesthesia monitor care could be improved by individualization of pharmacokinetic parameter estimated from the final model.

1.The sagittal and transverse diameters of 1,456 transverse foramina in 728cervical vertebrae were measured.The data are as follows:transverse diameter(mm) sagittal diameter (mm)Left Right Left RightMale(702 cases) 6.0?1.0 5.9?1.1 5.4?1.2 5.3?1.1Female(754 cases) 5.9?1.0 5.8?1.1 5.3?1.1 5.1?1.12.Among the 710 transverse foramina of 357 cervical vertebrae observed,mostof them are of the elliptical type.3.19.3% of double transverse foramen were found in 710 transverse foraminawhich were mostly encountered at the 6 th cervical vertebra.4.The mean value of the external diameter of the cervical part of the vertebralartery is 4?0.7mm.in 40 sides of specimens.5.63.1% of the vertebral artery in the 710 transverse foramina were foundmedial to its accompanying vein.6.According to the relationship between the sagittal(X_1)and transversediameter(X_2)of the transverse foramen and the diameter(Y)of the vertebralartery,a formula,(?)=1.859+0.172 X_1+0.24 X_2,of multiple regression was formulatedThus,the estimated diameter of the vertebral artery from the sagittal diameter X_1and transverse diameter X_2 of the transverse foramen could be obtained and it maybe helpful for clinical practice.7.In case of arthrosis,the vertebral artery could be compressed by the unco-vertebral joint which are found mostly at the level of the 4~5th cervicalvertebrae.
ABSTRACT
The sagittal and transverse diameters of spinal canal were measured from 344 cases including dry specimens,preserved vertebral colomns and X-ray films.Based on these data several conclusions have been drawn. (1)The morphology of spinal canal is consistent with the external feature of spinal cord. (2)The mean values of various measurement of cervical(C),thoracic(T),and lumbar(L)vertebrae of spinal canal in dry specimens are as follows: Transverse diameter(mm.) Sagittal diameter(mm.) C T L C T L Male 23.6 16.7 23.4 14.4 14.9 16.5 Eemale 23.1 16.1 22.4 13.7 14.2 16.0 (3)The mean values of measurement of spinal canal in X-ray films are as fol- lows: Transverse diameter(mm.) Sagittal diameter(mm.) L C L Male 27.8 16.5 19.8 Female 27.0 15.7 19.1 The data measured from X-ray films are approximately 20% larger than those from the actual specimens. (4)The ratio between the sagittal diameters of the cervical canal and vertebral body is 80~90% in male and 90~100% in female.The normal ratio between the products of sagittal and transverse diameters of the lumbar spinal canal and of the vertebral body is 1:4.Ratios lower than this value is considered to denote a diagnostic significance for spinal stenosis.
