Objective To explore the risk factors for vaginal stump recurrence after early cervical cancer surgery.Methods A total of 243 patients who underwent radical cervical cancer surgery in the First Affiliated Hospital of Henan University of Science and Technology from January 2018 to March 2020 were selected as the research subjects and divided into recurrence group(n=21)and non-recurrence group(n=22)based on whether vaginal stump recurrence occurred within 3 years after surgery.The clinical data of patients in the two groups,including age,pathological type,International Federation of Gynecology and Obstetrics(FIGO)staging of cervical cancer,degree of tissue differentiation,surgical approach,distance between surgical margin and tumor,muscle layer infiltration,presence or absence of lymph node involvement at diagnosis of cervical cancer,number of tumor budding,presence or absence of vascular cancer thrombus,vaginal resection length,and postoperative radiotherapy site were collected.One-way analysis of variance and binary logistic regression were used to analyze the risk factors for vaginal stump recurrence after early cervical cancer surgery.Results The recurrence rate of vaginal stumps within 3 years after early cervical cancer surgery was 8.64％(21/243).There were statistically significant differences in the pathological types,distance between surgical margin and tumor,muscle layer infiltration,number of tumor budding,vaginal resection length,and postoperative radiotherapy site of patients between the recurrence group and non-recurrence group(P＜0.05);there was no statistically significant difference in the age,FIGO stage,degree of tissue differentiation,surgical approach,presence or absence of lymph node involvement at diagnosis of cervical cancer,presence or absence of vascular cancer thrombus of patients between the two groups(P＞0.05).The binary logistic regression analysis showed that the distance between the surgical margin and the tumor≤3.5 mm,the number of tumor budding＞5,and the vaginal resection length≤2 cm were risk factors for vaginal stump recurrence after early cervical cancer surgery(P＜0.05),while postoperative pelvic radiotherapy combined with vaginal brachytherapy was a protective factor for vaginal stump recurrence after early cervical cancer surgery(P＜0.05).Conclusion The risk of vaginal stump recurrence after early cervical cancer surgery is high.The distance between the surgical margin and tumor≤3.5 mm,the number of tumor budding＞5,and the vaginal resection length≤2 cm are risk factors for vaginal stump recurrence after early cervical cancer surgery;pelvic radiotherapy combined with vaginal brachytherapy can reduce the risk of vaginal stump recurrence after early cervical cancer surgery.

BACKGROUND:The type of graft selected during anterior cruciate ligament revision is considered one of the main factors affecting the postoperative outcome,but there are few reports on the comparison between different graft materials. OBJECTIVE:To explore the medium-to-long-term clinical efficacy after anterior cruciate ligament revision with autologous ligament,allogeneic ligament,and LARS artificial ligament. METHODS:A total of 67 patients with the first anterior cruciate ligament revision admitted to the Department of Joint and Sports Medicine,The Second Hospital of Tangshan from May 2011 to May 2020 were selected,including 41 males and 26 females,with a mean age of(45.83±7.39)years.They were divided into three groups according to different grafts used:autologous ligament group(n=24),allogeneic ligament group(n=22),and LARS artificial ligament group(n=21).Follow-up for more than 36 months after revision was performed to evaluate the effect of revision. RESULTS AND CONCLUSION:(1)International Knee Documentation Committee(IKDC)score,Lysholm knee score,and Tegner motor score 1 year after surgery and at the last follow-up in the three groups were higher than those before surgery(P<0.05).There were no significant differences in IKDC score,Lysholm knee score,and Tegner motor score among the three groups 1 year after surgery and the last follow-up(P>0.05).(2)The lateral differences of KT-1000 at 1 year after surgery and the last follow-up among the three groups were lower than those before surgery(P<0.05).The lateral difference of KT-1000 and the positive rate of the axial shift test in the last follow-up of the LARS artificial ligament group were higher than those in the autologous ligament group and allogeneic ligament group(P<0.05).(3)At the last follow-up,X-ray films showed no obvious enlargement of the reconstructed bone tunnel and no obvious failure of the graft fixation device.There was no obvious aggravation of osteoarthritis,but bone density decreased significantly in some elderly patients.(4)These findings suggest that anterior cruciate ligament revision with LARS artificial ligaments can obtain good initial stability,but with the extension of time,the stability of partial cases tends to decrease,even with reconstructed ligament failure.Both allogeneic and autogenous ligaments can obtain good clinical efficacy in anterior cruciate ligament revision.

Objective To investigate the efficacy and safety of fluzopril in the treatment of platinum-sensitive recurrent epithelial ovarian cancer.Methods A total of 107 patients with platinum-sensitive recurrent epithelial ovarian cancer admitted to the First Affiliated Hospital of Henan University of Science and Technology from January 2019 to December 2020 were selected as the subjects.According to treatment methods,the patients were divided into control group(n=50)and observation group(n=57).The patients in the control group received a first-line chemotherapy regimen of paclitaxel combined with platinum:on the first day,intravenous infusion with paclitaxel injection 135 mg·m-2 was administered;on day 1-3,intravenous drip with cisplatin 50-60 mg·m-2 was administered;21 days was one chemotherapy cycle.On the basis of the treatment in the control group,the patients in the observation group were given fluzoparide capsules orally,150 mg each time,twice a day,and the treatment continued until disease progression or unacceptable toxic reactions occurred;21 days was one chemotherapy cycle.The patients in both groups received three consecutive chemotherapy cycles.The clinical efficacy,prognosis within 2 years after chemotherapy,Karnofsky Performance Status(KPS)score before and after chemotherapy,and incidence of adverse reactions during chemotherapy of patients between the two groups were compared.Results After 3 cycles of chemo-therapy,the disease control rate and objective remission rate of patients in the observation group were significantly higher than those in the control group(x2=5.420,4.220;P＜0.05).Following up to 24 months,the progression free survival of patients in the observation group was significantly longer than that in the control group(t=6.702,P＜0.05);there was no statistically significant difference in 1-year survival rate of patients between the two groups(x2=0.415,P＞0.05);the 2-year survival rate of patients in the observation group was significantly higher than that in the control group(x2=5.420,P＜0.05).Before chemotherapy,there was no statistically significant difference in KPS scores of patients between the two groups(t=0.537,P＞0.05);the KPS scores of patients in the two groups after three cycles of chemotherapy were significantly higher than those before chemotherapy(t=5.604,9.378;P＜0.05);after three cycles of chemotherapy,the KPS score of patients in the observation group was significantly higher than that in the control group(t=2.608,P＜0.05).The patients in both groups experienced hematological and non-hematological adverse reactions during chemotherapy;the main hematological adverse reactions was bone marrow suppression,most of which were Ⅲ ° and Ⅳ ° adverse reactions;the non-hematological adverse reactions included alo-pecia,gastrointestinal reactions,and liver and kidney dysfunction,most of which were Ⅰ°and Ⅱ°adverse reactions.There were no chemotherapy related deaths of patients in both groups.The incidence rates of anemia,thrombocytopenia,neutropenia,leuko-penia,lymphopenia,nausea,vomiting,fatigue,loss of appetite,hair loss,elevated serum creatinine,and elevated alanine amino-transferase(ALT)of patients during chemotherapy in the control group were 68.00％(34/50),72.00％(36/50),58.00％(29/50),68.00％(34/50),22.00％(11/50),26.00％(13/50),24.00％(12/50),46.00％(23/50),30.00％(15/50),50.00％(25/50),20.00％(10/50),10.00％(5/50),respectively;the incidence rates of anemia,thrombocytopenia,neutropenia,leukopenia,lymphopenia,nausea,vomiting,fatigue,loss of appetite,hair loss,elevated serum creatinine,and elevated ALT of patients during chemotherapy in the observation group were 61.40％(35/57),63.16％(36/57),49.12％(28/57),52.63％(30/57),21.05％(12/57),22.81％(13/57),24.56％(14/57),42.11％(24/57),29.82％(17/57),47.37％(27/57),21.05％(12/57),10.53％(6/57),respectively.There was no statistically significant difference in the incidences of anemia,thrombocytopenia,neutropenia,leukopenia,lymphopenia,nausea,vomiting,fatigue,loss of appetite,hair loss,elevated serum creatinine,and elevated ALT of patients during chemotherapy between the control group and the observation group(x2=0.047,0.000,0.041,0.694,0.056,0.000,0.208,0.041,0.184,0.160,0.233,0.102;P＞0.05).Conclusion For patients with platinum-sensitive recurrent ovarian cancer,the combination of paclitaxel and platinum chemo-therapy combined with fluzopril can effectively improve the anti-tumor effect,prolong the progression-free survival,improve survival rate and quality of life,and the adverse reactions are controllable.

Objective:To explore the common risk factors of intracerebral hemorrhage(ICH) in young people and to establish a predictive model of nomogram.Methods:The relevant data of young patients with ICH (≤45 years ) hospitalized in the Department of Neurosurgery of Dezhou people's Hospital from January 2014 to August 2021 were retrospectively studied, and the young group who underwent physical examination in the Physical Examination Center of Dezhou people's Hospital at the same time were randomly selected as the control group. Analyze the risk factors that may affect cerebral hemorrhage in young people, screen the risk factors with statistical differences through single factor analysis, screen the independent risk factors according to multi factor Logistic regression analysis, construct the risk nomogram model of cerebral hemorrhage in young people, and test the efficiency, goodness of fit and benefit of the constructed model through internal validation.Results:Compared with the control group, there were statistically significant differences in family history (χ 2=115.66, P<0.001), hypertension grade( Z=17.67, P<0.001), smoking history (χ 2=33.91, P<0.001), drinking grade ( Z=4.84, P<0.001), body mass index (BMI) ( t=11.76, P<0.001), low density lipoprotein ( t=4.78, P<0.001), high density lipoprotein cholesterol ( t=5.83, P<0.001),blood glucose ( Z=5.68, P<0.001) and homocysteine ( Z=2.22, P<0.001) in the case group. Binary Logistic regression analysis showed that hypertension grade ( OR=3.457, 95%CI: 2.809-4.254, P<0.001), family history ( OR=2.871, 95%CI:1.868-4.413, P<0.001), BMI ( OR=1.093, 95%CI:1.040-1.148, P<0.001), high density lipoprotein cholesterol ( OR=0.230, 95%CI:0.111-0.480, P<0.001), blood glucose ( OR=3.457, 95%CI:2.809-4.254, P<0.001), homocysteine (O R=3.457, 95%CI:2.809-4.254, P<0.001) was an independent risk factor for intracerebral hemorrhage in young adults. The nomogram prediction model showed that BMI was 96 points, hypertension grade was 100 points, family history was 30 points, high density lipoprotein cholesterol was 76 points, homocysteine was 48 points, blood glucose was 52 points,homocysteine was 48 points and blood glucose was 52 points, respectively. The consistency coefficient of the prediction model was 0.874. The nomogram dependent ROC curve AUC was 0.891, and the corresponding sensitivity and specificity were 74.5% (263/353) and 89.7% (437/487), respectively, a nomogram model was established with good diagnostic efficiency. Conclusion:The nomogram model established in this study can predict the probability of intracerebral hemorrhage in high-risk population, and take intervention measures as early as possible to prevent the occurrence of intracerebral hemorrhage in young people.

BACKGROUND/AIMS: This study aimed to investigate the precise mechanism and function of miR-16 in heat-denatured primary human dermal fibroblasts. METHODS: Primary human dermal fibroblasts were separated from normal human skin samples. Under heat stress, the levels of miR-16 and heat shock protein 70 (HSP70) were detected in primary human dermal fibroblasts by quantitative real-time polymerase chain reaction (qRT-PCR). Next, heat-denatured cells were transfected with synthetic scrambled negative control (NC) RNA (NC group), miR-16 mimics, miR-16 inhibitor or miR-16 inhibitor accompanied by small interfering RNA targeting HSP70, then the mRNA level of HSP70 was detected by qRT-PCR, cell proliferation was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and AlamarBlue assay, cell migration was examined by Transwell assay and cell apoptosis was assessed by transferase dUTP (deoxyuridine triphosphate) nick end labeling (TUNEL) assay. In addition, cell apoptosis-related proteins, Bax and Bcl-2, were detected by Western blotting. RESULTS: Heat stress significantly reduced miR-16 level and increased the mRNA level of HSP70 compared with untreated cells (p < 0.05). Overexpressed miR-16 reduced the mRNA level of HSP70, suppressed cell proliferation (p < 0.05 or p < 0.01), migration (p < 0.05), and promoted cell apoptosis (p < 0.001) compared with the NC group. Down-regulated miR-16 exerted an opposite effect on primary human dermal fibroblasts with heat-denaturation. Furthermore, effects of miR16 down-regulation on cell proliferation and migration were reversed by HSP70 silence. CONCLUSIONS MiR-16 might have an inhibitory effect on cell proliferation and migration in heat-denatured human dermal fibroblasts, and HSP70 might be associated with the cell proliferation and migration as a target gene of miR-16.

[Objective] To systematically study the characteristics of the key syndromes of systemic lupus erythematosus(SLE),summarize its clinical efficacy,and explore the mechanism of traditional Chinese medicine(TCM).[Methods] The main clinical syndrome features of SLE are heat-toxicity,blood stasis and Yin-deficiency.Compared with glucocorticoids(GCs) alone,combination with JP can significantly improve the clinical efficacy and reduce the glucocorticoid treat consumption effectively.[Results]Our results showed that in MRL/LPR model mice,JP could restore the balance between TH17 and regulatory T cells through CaMK4 signaling pathway,and the interaction between T cells and B cells.JP could promote DNA methylation,inhibit the over-activated lymphocytes,improve the prognosis of SLE and prevent renal damage.JP could up-regulate the concentration of eicosapentaenoic acid (EPA) and the level of glycine,phenylalanine and tryptophan dramatically.Furthermore,JP could reduce the abundance of pathogenic bacteria(such as Parabacteroides) and increase the abundance of beneficial bacteria (such as Odoribacter and Ruminococcus) by regulating gastrointestinal function,which was not found in GCs treated subjects.JP can also obviously reduce the expression of TLR7,TLR9 and IL-6 in intestinal mucosa,showing the effect of multi-target therapy on SLE.[Conclusion] The most common clinical syndromes of SLE are heat-toxicity,blood stasis and Yin-deficiency.JP can effectively control the progress of SLE and exert its clinical function from different aspects.Our research laid the scientific basis for the popularization and application of TCM in clinical treatment of SLE.

Objective To understand the status of Clonorchis sinensis infection and its risk factors in Futian District Shen?zhen City so as to provide the evidence for formulating the strategy of prevention and control. Methods Two monitoring points were randomly selected and the permanent population aged≥3 years were investigated and their stool samples were detected for the eggs of C. sinensis by using Kato?Katz technique. Meanwhile the risk factors of infection were also investigated. Results A total of 743 subjects were examined and 7 persons were infected with C. sinensis and the infection rate was 0.94%. Most of the infected cases were focused on 20?40 and 40?60 age groups.
