Objective To investigate the effects of “patient-family-community”health promotion mode on patients with impaired glucose regulation(IGR).Methods Using the function of random case samples in SPSS,we randomly chose an experimental village and a control village respectively from all villages in Zhuqiao of Pudong New Area.Altogether 75 IGR patients who met the requirement were filtered in the two villages. According to the villages they belonging to,39 of them were divided into experimental group and 36 to control group.From March 201 4 to August 201 4, subjects in the experimental group were intervened by“patient-family-community”health promotion mode,while participants in the control group used the regular health guidance.We compared the test score of knowledge-attitude-practice (KAP) questionnaire,family APGAR questionnaire and blood glucose between two groups.Results Relevant indexes of the two groups before intervention showed no difference (P >0.05).After intervention,the knowledge(K),attitude(A)and practice (P)test scores of the experimental group were (8.85 ±1 .31 ),(8.87 ±1 .77)and (6.92 ±2.67),higher than (5.86 ±2.37),(6.78 ±2.92)and (3.89 ±3.02)of the control group(Z =-5.1 89,-3.299,-4.042;P <0.05).The APGAR test scores of the experimental group(7.56 ±1 .90)was higher than(6.47 ±1 .77)of the control group(t =2.571 ,P <0.05).The FPG,2hPG and HbA1 c of the experimental group were (5.86 ± 0.50)mmol/L,(8.02 ±0.72)mmol/L and(5.73 ±0.42)%,which were lower than (6.1 1 ±0.45)mmol/L, (8.60 ±0.97)mmol/L and(5.97 ±0.53)% of the control group (t =-2.293,-2.383,-2.1 70;P <0.05).Conclusions Applying “patient-family-community”health promotion mode can improve the KAP, family function of IGR patients,control their blood glucose better and prevent diabetes.

Background:The purpose of this study was to analyze cases of AO31-A2 intertrochanteric fractures (ITFs) and to identify the relationship between the loss of the posteromedial support and implant failure.Methods:Three hundred ninety-four patients who underwent operative treatment for ITF from January 2003 to December 2017 were enrolled.Focusing on posteromedial support,the A2 ITFs were divided into two groups,namely,those with (Group A,n =153) or without (Group B,n =241) posteromedial support post-operatively,and the failure rates were compared.Based on the final outcomes (failed or not),we allocated all of the patients into two groups:failed (Group C,n =66) and normal (Group D,n =328).We separately analyzed each dataset to identify the factors that exhibited statistically significant differences between the groups,In addition,a logistic regression was conducted to identify whether the loss of posteromedial support of A2 ITFs was an independent risk factor for fixation failure.The basic factors were age,sex,American Society of Anesthesiologists (ASA) score,side of affected limb,fixation method (intramedullary or extramedullary),time from injury to operation,blood loss,operative time and length of stay.Results:The failure rate of group B (58,24.07％) was significantly higher than that of group A (8,5.23％) (x2 =23.814,P ＜ 0.001).Regarding Groups C and D,the comparisons of the fixation method (P =0.005),operative time (P =0.001),blood loss (P =0.002)and length of stay (P =0.033) showed that the differences were significant.The logistic regression revealed that the loss of posteromedial support was an independent risk factor for implant failure (OR =5.986,95％ CI:2.667-13.432) (P ＜ 0.001).Conclusions:For AO31-A2 ITFs,the loss of posteromedial support was an independent risk factor for fixation failure.Therefore,posteromedial wall reconstruction might be necessary for the effective treatment of A2 fractures that lose posteromedial support.

Objective:To examine the ultrasound images, clinical features, intraoperative conditions, and pathological features of ovarian clear cell carcinoma(OCCC)during perimenopause, in order to improve the early diagnosis of OCCC via ultrasound examination.Methods:A retrospective analysis of 29 patients, aged 42-72(56.8±7.4)years, who were surgically treated and pathologically diagnosed with OCCC at our hospital between 1 September 2015 and 31 December 2022, including 10 in the non-menopausal phase, 3(10.3%)in early menopausal transition, 7(24.1%)in late menopausal transition, and 19(65.5%)in the post-menopausal phase.The number of pregnancies(1.86±1.04)and the number of births(0.97±0.56)were also recorded.Results:In 29 cases, the masses contained solid components, and the ultrasound manifestations were as follows: (1)single-compartment cystic masses(solid components accounted for <50% of the total volume)were found in 11 cases, with clear borders, regular morphology, ground-glass echoes inside the cystic cavity, multiple solid protrusions inside the cystic cavity, and blood flow signals inside the solid components on color Doppler flow imaging(CDFI); (2)multi-compartment cystic masses(solid components accounted for <50% of the total volume)occurred in 8 cases, with largely clear borders, ground-glass echoes inside the cystic cavity, multiple solid protrusions inside the cavity, thick walls where the protrusions were attached, varying thickness of walls separating the cystic cavities, and blood flow signals inside the solid components, walls where there were solid attachments and thicker parts of the separating walls on CDFI; (3)there were 7 cases with predominantly solid cystic masses(the solid components accounted for >50% of the total volume), unclear borders, poor translucency, irregular morphology of the solid components, uneven internal echoes, and blood flow signals in the solid component on CDFI; (4)solid masses(the solid components accounted for >95%of the total volume)were seen in 3 cases with unclear borders, irregular morphology, uneven internal echoes, and a small number of cystic cavities(cystic portion <5%), with poor translucency in the cystic cavities and blood flow signals in the solid components on CDFI.Intraoperative exploration of ascites was performed in 17 cases, and adhesion between the mass and surrounding organs was found in 27 cases.Postoperative pathological results revealed 26 cases with high grade tumors and 3 cases with intermediate grade tumors.There were 3 cases with bilateral OCCC, 13 with left side OCCC and 13 with right side OCCC.According to the FIGO pathological staging system, 12 cases were in stage Ⅰ, 10 in stage Ⅱ, 5 in stage Ⅲ and 2 in stage Ⅳ.Comparison of different pathological stages(early stages Ⅰ and Ⅱ versus late stages Ⅲ and Ⅳ)showed statistically significant differences in the ratio of pathological stages between patients with different ultrasonographic manifestations( χ2=11.163, P<0.05), and the results of two-by-two comparisons showed that OCCC patients with ultrasonographic manifestations of solid masses(solid component accounting for >95%of the total volume)were more often in the late stage at the time of onset, while OCCC patients with a high number of cystic components within the lesions were more likely to be in the early stage at the time of onset.OCCC patients with more cystic components in the lesions tended to have an earlier onset and a better prognosis. Conclusions:When ultrasound imaging shows primarily a single chamber cystic solid mass in a patient in the perimenopausal phase with an endometriosis history, together with signs of specialized examination and pelvic adhesion during transvaginal sonography, a diagnosis of OCCC should be suspected.It is of great significance to pay attention to transvaginal sonography examination, ultrasound image features and clinical symptoms in perimenopausal women for the early diagnosis of OCCC.

Objective:To analyze the clinical characteristics, therapeutic options and risk factors of mortality in patients with carbapenem-resistant Acinetobacter baumannii (CRAB) bloodstream infection, and to provide evidence for clinical treatment option and prognosis evaluation of CRAB bloodstream infections. Methods:A retrospective study was carried out in 224 patients with confirmed diagnosis of CRAB bloodstream infection during the period from January 2012 to December 2017 in West China Hospital, Sichuan University. The patients were divided into the death group and the survival group according to the survival status 28 days after collecting blood samples. The clinical features and therapeutic options of antibacterial drugs were reviewed. Student′s t test was used for analyzing normally distributed data and Mann-Whitney U test for non-normal data.Chi-square test was used for categorical variables. Univariate and multivariate logistic analysis were used to analyze the risk factors of mortality associated with CRAB bloodstream infection. Results:Among 224 cases of CRAB bloodstream infection, 121 cases died (54.02%). These patients were mainly in intensive care unit (ICU) and hematology department. The common underlying diseases were severe acute pancreatitis and severe cardiovascular events. The interleukin (IL)-6 level (median (interquartile range)) in the death group (480.40 ng/L (1 432.95 ng/L)) was higher than that of the survival group (107.05 ng/L (263.08 ng/L)), the difference was statistically significant ( Z=4.526, P<0.01). The procalcitionin (PCT) levels in the death group and the survival group were 3.81 μg/L (17.26 μg/L) and 2.12 μg/L (12.74 μg/L), respectively, with no difference between the two groups ( P>0.05). The death rate of empirical treatment with a single or more non-active antimicrobial agents was 57.14% (64/112), that of monotherapy with active agent was 45.68% (37/81), and that of combination therapy with at least one active drug was 64.52% (20/31). The differences had no statistical significance ( P=0.130). The logistic regression analysis showed that the risk factors of mortality associated with CRAB bloodstream infection were renal dysfunction (odds ratio ( OR)=2.181, P=0.024) and multiple organ dysfunction syndrome (MODS; OR=20.376, P<0.01). Conclusions:The fatality rate of patients with CRAB bloodstream infection is high. These patients with renal dysfunction or MODS have poor prognosis. In addition to early effective antibacterial therapy, individual comprehensive treatment should be implemented in order to improve the curative effect.

OBJECTIVE: To observe and compare the therapeutic effects of hydroxypropyl chitosan ferrous ion complex solution and ferrous sulfate solution in iron deficiency anemia rats and their effects on gastric mucosa. METHODS: Seven rats were randomly selected from thirty five SPF grade SD rats as control group, and were fed with normal diet, distilled water (E). The rest of SD rats were fed with low iron feed and distilled water plus continuous tail vein bloodletting to establish the iron deficiency anemia model. After the model was established successfully, the rats were randomly divided into four groups: blank control group (A), iron deficiency anemia control group (B), ferrous sulfate group (C), hydroxypropyl chitosan ferrous ion complex (HPCTS-Fe RESULTS: After modeling, except the normal control group, the hair color of the rats in the four groups showed dark yellow and the belly of the toes became white gradually. HGB, HCT, Ret%, MCV, MCH, MCHC and SF decreased significantly (P < 0.05). After treatment, the rats with dark yellow hair in group C and D were improved, and the toe abdomen turned pink gradually. RBC, HGB, HCT, Ret%, MCV, MCH, MCHC and SF in rats in group C and D increased, which were higher than those in group B (P < 0.05). The HGB of the rats in group D was higher than that of group C in day 28th during treatment and the Ret% was higher than that in group C at day 10th (P<0.05).After treatment, the liver and spleen of the rats in group C and D were lighter than those in group B (P<0.05).The gastric mucosa in group A, B, D and E was not damaged obviously, while it was slightly irritated and damaged in group C. CONCLUSION Hydroxypropyl chitosan ferrous complex solution can improve the hemoglobin level of SD rats with iron deficiency anemia, which is stronger than ferrous sulfate solution and shows no damage to gastric mucosa.

OBJECTIVE: To investigate the clinical characteristics and risk factors of acute leukemia complicated with multi-drug resistant bacterial septicemia in children. METHODS: The clinical data of children with acute leukemia complicated with septicemia admitted to the Affiliated Hospital of Guangdong Medical University from January 2013 to May 2021 were retrospectively analyzed. Their flora composition and drug resistance were also analyzed. The children were divided into multi-drug resistant bacteria (MDRB) group and non-multi-drug resistant bacteria (non-MDRB) group according to the drug sensitivity results, and the differences in clinical data between the two group were compared. RESULTS: A total of 108 children had drug sensitivity results, 47 cases in the MDRB group, including 26 strians of Gram-positive bacteria (G⁺), the most common multi-drug resistant G⁺ bacteria were coagulase-negative staphylococci (CoNS) and Staphylococcus aureus, and the most common multi-drug resistant Gram-negative bacteria G^- bacteria were Escherichia coli and Klebsiella pneumoniae subspecies pneumoniae. Compared with non-MDRB group, children in MDRB group had higher C-reactive protein (CRP) level and mortality rate (P <0.001, P =0.009), lower initial empirical anti-infection efficiency (P <0.001), and were more likely to have septic shock (P =0.003). Logistic analysis showed that the risk factors of acute leukemia complicated with MDRB septicemia in children were previous MDRB infection (OR =6.763, 95% CI: 1.141-40.092, P =0.035), duration of agranulocytosis before infection≥7 days (OR =3.071, 95% CI: 1.139-8.282, P =0.027), and previous use of antimicrobial drugs within 90 days before infection (OR =7.675, 95% CI: 1.581-37.261, P =0.011). CONCLUSIONS The clinical features of acute leukemia complicated with MDRB septicemia in children include a heavy inflammatory response, significantly elevated CRP, susceptibility to secondary septic shock, low efficiency of initial empirical anti-infective therapy, and high mortality rate. Previous MDRB infection, duration of agranulocytosis before infection≥7 days, and previous use of antimicrobial drugs within 90 days before infection are risk factors of acute leukemia complicated with MDRB septicemia in children.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Hypoxia is a prominent feature of tumors. Hypoxia-inducible factor-1α (HIF-1α), a major subunit of HIF-1, is overexpressed in hypoxic tumor tissues and activates the transcription of many oncogenes. Accumulating evidence has demonstrated that HIF-1α promotes tumor angiogenesis, metastasis, metabolism, and immune evasion. Natural products are an important source of antitumor drugs and numerous studies have highlighted the crucial role of these agents in modulating HIF-1α. The present review describes the role of HIF-1α in tumor progression, summarizes natural products used as HIF-1α inhibitors, and discusses the potential of developing natural products as HIF-1α inhibitors for the treatment of cancer.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.
