To study the characteristics of heart rate rhythm in pregnant women at different trimester of pregnancy, and to explore the relationship between the basic rhythm of heart rate and pregnancy complications. Thirteen pregnant women who were diagnosed with normal early pregnancy in the Reproductive Center of the Second Affiliated Hospital of Soochow University from June 2018 to December 2019 were prospectively selected. Personal files were created and the heart rate data of pregnancy women was collected 24 hours a day by wearable devices until delivery. Prenatal examination and pregnancy outcomes were surveyed at follow-up. The cosine analysis method and the designed statistical module were used to analyze the long-term rhythm of pregnant women's heart rate. The heart rate of pregnant women showed a significant rhythm at different gestational weeks. Compared with the gestational week of 12, the midline-estimating statistic of rhythm(MESOR) increased significantly at the gestational week of 28 and 32 (t=-2.751,P=0.013;t=-2.314,P=0.032).The phase of rhythm shifted from 14∶00 pm in the first trimester of pregnancy (12 weeks) to 16∶00 pm in the second trimester (24 weeks) (t=2.613,P=0.018) and returned to 14∶00 pm at the third trimester (32 weeks) (t=-2.176,P=0.046). Season had no significant effect on the changes of MESOR, amplitude and phase of maternal heart rate in the first trimester (t=-0.356,P=0.729;t=-0.777,P=0.464;t=-0.434,P=0.673), while season had no significant effect on the changes of MESOR, amplitude and phase in the third trimester (t=-0.663,P=0.532;t=-0.209,P=0.841;t=0.625,P=0.592). The heart rate of one pregnant woman with natural delivery had rhythm disorder from the start of labor to delivery. The heart rate of one pregnant woman with premature rupture of membranes showed rhythm disorder before and after the rupture of membranes, and smaller amplitude. Rhythm disturbance may play a suggestive role in preterm delivery and labor initiation. In conclusion, pregnancy may cause changes in the internal heart rate rhythm. Maternal internal rhythm disturbance may occur when delivery or premature rupture of membranes occurs. The heart rate rhythm of pregnant women may be related to some common complications of pregnancy such as premature rupture of membranes.

This study aimed to investigate the biological effects and underlying mechanisms of the total ginsenosides from Panax ginseng stems and leaves on lipopolysaccharide(LPS)-induced acute lung injury(ALI) in mice. Sixty male C57BL/6J mice were randomly divided into a control group, a model group, the total ginsenosides from P. ginseng stems and leaves normal administration group(61.65 mg·kg~(-1)), and low-, medium-, and high-dose total ginsenosides from P. ginseng stems and leaves groups(15.412 5, 30.825, and 61.65 mg·kg~(-1)). Mice were administered for seven continuous days before modeling. Twenty-four hours after modeling, mice were sacrificed to obtain lung tissues and calculate lung wet/dry ratio. The number of inflammatory cells in bronchoalveolar lavage fluid(BALF) was detected. The levels of interleukin-1β(IL-1β), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) in BALF were detected. The mRNA expression levels of IL-1β, IL-6, and TNF-α, and the levels of myeloperoxidase(MPO), glutathione peroxidase(GSH-Px), superoxide dismutase(SOD), and malondialdehyde(MDA) in lung tissues were determined. Hematoxylin-eosin(HE) staining was used to observe the pathological changes in lung tissues. The gut microbiota was detected by 16S rRNA sequencing, and gas chromatography-mass spectrometry(GC-MS) was applied to detect the content of short-chain fatty acids(SCFAs) in se-rum. The results showed that the total ginsenosides from P. ginseng stems and leaves could reduce lung index, lung wet/dry ratio, and lung damage in LPS-induced ALI mice, decrease the number of inflammatory cells and levels of inflammatory factors in BALF, inhibit the mRNA expression levels of inflammatory factors and levels of MPO and MDA in lung tissues, and potentiate the activity of GSH-Px and SOD in lung tissues. Furthermore, they could also reverse the gut microbiota disorder, restore the diversity of gut microbiota, increase the relative abundance of Lachnospiraceae and Muribaculaceae, decrease the relative abundance of Prevotellaceae, and enhance the content of SCFAs(acetic acid, propionic acid, and butyric acid) in serum. This study suggested that the total ginsenosides from P. ginseng stems and leaves could improve lung edema, inflammatory response, and oxidative stress in ALI mice by regulating gut microbiota and SCFAs metabolism.

【Objective】 To compare the clinical safety and effectiveness of super-mini-percutaneous nephroscope (SMP) combined with flexible ureteroscopic lithotripsy (FURL) in oblique supine lithotomy position and FURL alone in the treatment of 2.0-3.0 cm renal calculi. 【Methods】 Clinical data of 55 patients treated during Jan.2018 and May 2021 were retrospectively analyzed, including 47 cases complicated renal calculi, and 14 cases of lower calyceal calculi with infundibulopelvic angle ≤30°. SMP combined with FURL was performed in 23 cases (combined group), and FURL alone was performed in 32 cases (FURL group). The operation time, hemoglobin reduction, postoperative hospital stay, hospitalization expenses, stone-clearance rate and complications were compared. 【Results】 All operations were successful. Compared with the FRUL group, the combined group had significantly more hemoglobin reduction [(16.30±10.17) g/L vs. (6.94±6.61) g/L], longer postoperative hospital stay [(5.35±1.61) d vs. (3.19±1.26) d], and higher hospitalization expenses [(22 481±2 234) yuan vs. (18 209±2 584) yuan] (P0.05]. One month after surgery, CT results showed that the combined group had higher stone-clearance rate (91.30% vs. 65.63%, P=0.027). There was no difference in the complication rate (21.74% vs. 21.88%, P>0.05). One case (4.35%) in the combined group and 5 cases (15.63%) in the FURL group received retreatment (P>0.05). 【Conclusion】 SMP combined with FURL in oblique supine lithotomy position is safe and effective in the treatment of 2.0-3.0 cm renal calculi, with high stone-clearance rate and low complication rate.
Résumé
Risk prediction models play an important role in the primary prevention of cardiovascular diseases (CVD) in the elderly population. There are fifteen papers about CVD risk prediction models developed for the elderly domestically and internationally, of which the definitions of disease outcome vary widely. Ten models were reported with insufficient information about study methods or results. Ten models were at high risk of bias. Thirteen models presented moderate discrimination in internal validation, and only four models have undertaken external validation. The CVD risk prediction models for the elderly differed from those for the general population in terms of model algorithm and the effect size of association between predictor and outcome, and the prediction performance of the models for the elderly attenuated. In the future, high-quality external validation researches are necessary to provide more solid evidence. Different ways, including adding new predictors, using competing risk model algorithms, machine learning methods, or joint models, and altering the prediction time horizon, should be explored to optimize the current models.

Objective:To observe the effect of fluoride on growth and development of bone microstructure of rats condyle subchondral bone (RCSB).Methods:Forty two 3-week-old SD rats (half male and half female) were fed adaptively for 1 week, and 3 females and 3 males were sacrificed and recorded as 0 month. The remaining rats were randomly divided into control group ( n = 18) and fluoride exposed group ( n = 18) according to their body weight (55 - 70 g), half male and half female. The fluoride exposed group was fed with 150 mg/L sodium fluoride (NaF) aqueous solution, and the control group was fed with tap water. The two groups of experimental animals were sacrificed at 3, 5 and 7 month, respectively, 6 rats in each group, half male and half female. The right mandibular condyle was separated, and Micro CT scanning was performed to detect the microstructure parameters of RCSB. Results:In fluoride exposed group (3 month), bone surface/tissue volume (BS/TV), bone surface/bone volume (BS/BV), trabecular thickness (Tb.Th), trabecular number (Tb.N), structure model index (SMI), connectivity, connectivity density (Conn.D) and total porosity of female rats were significantly different from those of male rats ( t = - 5.10, - 5.58, 4.52, - 4.32, - 4.03, - 2.81, - 6.71, - 3.32, P < 0.05). There was no significant difference in each index between female and male rats in fluoride exposed group (5, 7 month, P > 0.05). Conclusion:In chronic fluorine exposure bone environment, the RCSB bone microarchitecture of male and female rats is different with time, showing the tendency of fluoride injury that the bone changes of female rats are slowed and the bone changes of male rats are active.
Résumé
Background A large number of studies on fluoride-induced systemic bone damage have been reported previously, but there is little understanding of the characteristics of fluoride accumulation in jawbone. Jawbone is homologous to the other bone tissues in the body, and is an indispensable and important frame structure in the oral cavity. Objective To study fluoride accumulation and its change trends in teeth, jawbone, and femur of SD rats with chronic drinking-water-borne fluorosis. Methods A total of 144 three-week-old SD rats, half male and half female, were randomly divided into two groups, a normal control group and a fluoride group. The rats in the normal controlgroup drank purified water disinfected and filtered from Guizhou, and the water contained 0.08 mg·kg−1 fluoride which was lower than the national water quality standard at 1 mg·kg−1. The rats in the fluoride group were fed with sodium fluoride (NaF) solution with a concentration of 150 mg·L−1. At 3, 5 and 7 months of the fluoride exposure, the levels of fluoride in urine, blood, teeth, jawbone, and femur were measured by fluoride ion electrode method. Results There was no sex difference in fluoride content in different biological samples of rats in the fluoride group and the normal control group (all P>0.05). After 3 months of fluoride exposure, the rats in the fluoride group showed dental fluorosis of grade II, and higher levels of fluoride ion in blood and urine than the normal control group (all P<0.05), indicating that the rat model of fluoride drinking-water-borne chronic fluorosis was successfully replicated. In the normal control group, the levels of fluoride in femur remained stable; at the end of 3 months, the levels of fluoride in jawbone and teeth were (1097.36±470.34) and (453.09±173.43) mg·kg−1 respectively, and at the end of 7 months, the levels of fluoride in jawbone and teeth were (2113.18±634.49) and (1604.80±160.43) mg·kg−1 respectively. Both jawbone and teeth showed a positive temporal effect of increasing fluoride accumulation (P<0.05). After continuous fluoride feeding, the fluoride levels in jawbone, teeth, and femur of rats in the fluoride group were (3145.02±765.82), (1550.20±77.73), and (3640.55±699.42) mg·kg−1 after 3 months, and (8420.36±1728.56), (4702.08±1417.06), and (6091.99±1384.97) mg·kg−1 after 7 months. The three kinds of hard tissues all showed a positive temporal effect of increasing fluoride accumulation (P<0.05), and the cumulative increas was large than that in the normal control group. Among them, jawbone fluorine increased most. At the end of 5 months, the levels of fluoride in jawbone, femur, and teeth were (6485.02±2141.98), (4914.99±1529.41), and (3365.21±1462.27) mg·kg−1 respectively, and the levels of fluoride in jawbone was much higher than those in femur and teeth (P<0.05). Conclusion Hard tissues such as bones and teeth are fluorine sensitive tissues. Compared with femur, jawbone showed significantly high fluoride accumulation, while teeth show relatively lagging fluoride accumulation.

OBJECTIVE@#To summarize the complications of core drilling intramedullary nail in the treatment of femoral shaft closed fracture and explore the treatment strategy.@*METHODS@#From August 2014 to June 2018, a total of 215 patients with closed femoral shaft fractures were treated with closed reduction core drill intramedullary nail, including 129 males and 86 females, aged from 18 to 62 years, with an average of (44.2±10.6) years old. The time from injury to operation was 3 to 21 days. There were 102 cases of AO type A fracture, 82 cases of AO type B fracture and 31 cases of AO type C fracture. The time of operation, the amount of blood loss during operation, the duration of hospitalization, the time of fracture healing and the HSS score of knee joint function at the last follow-up were recorded. The observation of complications included:iatrogenic fracture, core drill broken, core drill twist, postoperative infection, and fracture nonunion.@*RESULTS@#The average operation time was (63.2± 15.6) min and intraoperative blood loss was (150.0±34.5) ml. All the incisions reached grade A healing. Patients were follow up for a mean of (18.5±3.2) months, the average hospital stay was (4.3±1.2) days, and the average fracture healing time was (5.6±2.3) months. At the final follow-up, the average HSS score of knee joint was 90.3±4.7. Related complications occurred in 37 cases (17.2%). The core drill related complications occurred in 13 cases (6.0%), including core drill broken in 5 cases (2.3%), core removal in 1 case and slotting in 4 cases;core drill twist in 8 cases (3.7%). After the core was cut, the core was removed. Similar complicationsof conventional intramedullary nail:iatrogenic fracture was performed in 12 cases (5.6%), including 10 cases of fracture end split and 2 cases of distal perimedullary fracture of intramedullary nail. The patients with cleavage at the fracture end were not treated after judging their stability, and the patients with fracture around the distal end of the intramedullary nail were fixed with auxiliary steel plate during operation;1 case(0.4%) with delayed infection after operation, debridement and external fixation was replaced and healed after bone transfer; fracture nonunion occurred in 11 cases (5.1%), of which 7 cases (3.3%) were hypertrophic nonunion and healed with additional plate. Atrophic nonunion occurred in 4 cases (1.9%), which healed after additional steel plate and bone graft.@*CONCLUSION@#Core drilling intramedullary nail is an effective method for the treatment of closed femoral shaft fracture, and the complications include core drill related complications and conventional intramedullary nail similar complications. Accurate preoperative evaluation, careful operation during operation and early postoperative symptomatic treatment can effectively reduce the occurrence of related complications.

The DNR decision in EDs has not been extensively studied, especially in the Chinese mainland. METHODS: This retrospective chart study of all deceased patients in the ED of a university hospital was conducted from January 2017 to December 2019. The patients with out-of-hospital cardiac arrest were excluded. RESULTS: There were 214 patients’ deaths in the ED in the three years. Among them, 132 patients were included in this study, whereas 82 with out-of-hospital cardiac arrest were excluded. There were 99 (75.0%) patients’ deaths after a DNR order medical decision, 64 (64.6%) patients signed the orders within 24 hours of the ED admission, 68 (68.7%) patients died within 24 hours after signing it, and 97 (98.0%) patients had DNR signed by the family surrogates. Multivariate analysis showed that four independent factors influenced the family surrogates’ decisions to sign the DNR orders: lack of referral (odds ratio [OR] 0.157, 95% confidence interval [CI] 0.047-0.529, P=0.003), ED length of stay (ED LOS) ≥72 hours (OR 5.889, 95% CI 1.290-26.885, P=0.022), acute myocardial infarction (AMI) (OR 0.017, 95% CI 0.001-0.279, P=0.004), and tracheal intubation (OR 0.028, 95% CI 0.007-0.120, P<0.001). CONCLUSIONS: In the Chinese mainland, the proportion of patients consenting for DNR order is lower than that of developed countries. The decision to sign DNR orders is mainly affected by referral, ED LOS, AMI, and trachea intubation.

Objective:To evaluate the relationship between dyslipidemia and uric acid urolithiasis, and explore the risk factors of uric acid urolithiasis.Methods:93 patients with uric acid urolithiasis identified by stone composition analysis were retrospective analyzed from January 2014 to October 2019 were classified as uric acid urolithiasis group.Among them there were 77 men accounting for 82.8%, 16 women accounting for 17.2%, the median age is 64 years old.According to sex, age and other conditions, 321 patients with calcium oxalate urolithiasis in the same period were selected as calcium oxalate stone group. Among them there were 264 men accounting for 82.2%, 57 women accounting for 17.8%, the average age is 64 years old.While 306 non-stone people examined in hospital as control group in the same period who matched with age and gender. Among them there were 252 men accounting for 82.4%, 54 women accounting for 17.6%, the average age is 61 years old. There was no significant difference in age and sex ratio among the three groups. The body mass index (BMI) of uric acid urolithiasis group, calcium oxalate urolithiasis group and control group were significantly different( P<0.01). Serum uric acid, urine pH and blood lipids: triglyceride (TG), cholesterol (TC), high density lipoprotein (HDL-C) and low density lipoprotein (LDL-C) were recorded in the three groups, and the correlation between the above indexes and stone composition was analyzed.The uric acid urolithiasis group was divided into hyperuricemia(HUA) group (n=41) and Non HUA group (n=52) according to serum uric acid, and 66 cases with HUA were selected in the control group. The dyslipidemia and urine pH levels of the above three groups were compared. The multivariate Logistic regression analysis was used to identify the independent risk factors associated with uric acid urolithiasis formation. Results:There were significant differences in TG level, incidence of hypertrigly-ceridemia, low HDL-cholesterolemia, high LDL-cholesterolemia, serum uric acid and urine pH between uric acid urolithiasis group and calcium oxalate urolithiasis group( P<0.05). Significant differences were seen in TG level, HDL-C level, incidence of hypertriglyceridemia and low HDL-cholesterolemia, serum uric acid and urine pH between uric acid urolithiasis group and control group.There was significant difference in urine pH between uric acid urolithiasis with and Non HUA group. Significant difference in the incidence of hypertriglyceridemia and low HDL-cholesterolemia were seen between uric acid urolithiasis with HUA group and HUA group.Multivariate Logistic regression analysis showed that obesity(odds ratio=1.68, P<0.001), hypertriglyceridemia(odds ratio=7.37, P=0.002), low HDL-cholesterolemia(odds ratio=10.46, P=0.001) and low urinary pH(odds ratio=0.10, P<0.001) were independent risk factors for uric acid urolithiasis. Conclusions:Dyslipidemia was more likely associated with uric acid urolithiasis. Obesity, hypertriglyceridemia, low HDL-cholesterolemia and low urinary pH are closely related to the occurrence of uric acid urolithiasis.
Résumé
Objective:To investigate the effect of Ru′ai Shuhou prescription (RSR) drug-containing serum on the proliferation and invasion ability of breast cancer cells MDA-MB-453 based on the biological axis of stromal cell-derived factor-1(SDF-1)/chemokine receptor 4 (CXCR4). Method:A model of MDA-MB-453 cells with SDF-1-induced high expression of CXCR4 was established, and the rat drug-serum containing RSR and blank rat serum were prepared respectively. The cells were divided into fetal bovine serum control group (Blank), blank rat serum group, SDF-1+blank rat serum group, SDF-1+RSR group, AMD3100+ SDF-1+blank rat serum group, and AMD3100+ SDF-1+RSR group. After intervention for 48 h, cell proliferation was detected by cell counting kit-8 (CCK-8) assay, cell invasion ability was detected by transwell assay, and mRNA and protein expressions of CXCR4, matrix metalloproteinase-2 (MMP-2) and MMP-9 were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. Result:As compared with the blank serum group, the proliferation of MDA-MB-453 cells was promoted and expression of CXCR4 mRNA was increased significantly when SDF-1 was 100 μg·L-1 (P<0.05). As compared with SDF-1+blank rat serum group, RSR inhibited the proliferation and invasion of MDA-MB-453 cells induced by SDF-1, and at the same time, down-regulated the mRNA and protein expressions of CXCR4, MMP-2 and MMP-9 (P<0.05). After pre-treatment with AMD3100 for 24 h, the inhibitory effect of RSR to cell proliferation was significantly increased (P<0.05), and meanwhile, the decreases in mRNA and protein expression of CXCR4, MMP-2 and MMP-9 were more obvious, with statistically significant differences (P<0.05). Conclusion:Through SDF-1/CXCR4 biological axis, RSR could down-regulate the expression of MMP-2 and MMP-9, reduce the degradation of extracellular matrix (ECM), and then inhibit the metastasis of MDA-MB-453 cells. In addition, it has a synergistic effect with CXCR4 inhibitor AMD3100.

Objective To evaluate the effectiveness of a newly designed modular flexible ureteroscope with holmium laser lithotripsy for the treatment of renal calculi based. Methods 40 patients were treated with modular flexible ureteroscopic lithotripsy (German Polydiagnost) with holmium laser. 40 patients were treated by traditional flexible ureteroscopic lithotripsy. Their therapeutic effects were compared. Results For modular flexible ureteroscopic lithotripsy group, 37 patients underwent successful operation, with lithotripsy with operation time of (86.0 ± 34.4) min and postoperative hospital stay of (5.3 ± 1.6) days. No severe complication including ureteral perforation, high fever or severe bleeding occurred. One month after the operation, KUB and B-ultrasonography showed complete stone free in 35 patients. Residual calculi (0. 4 cm in diameter) in the calyces were found in 2 patients. Medication and postural drainage therapy were applied. Two weeks later , KUB and B-ultrasonography showed that the residual stones have been removed completely. There was no significant differences in stone size , operation time, rate of calculus clearance, the incidence of postoperative complications, operating time and duration of postoperative hospitalization between the traditional flexible ureteroscopic lithotripsy group and modular ureteroscopic lithotripsy group. Conclusions The modular flexible ureteroscope is effective and safe in treating reanl calculi.
