Objective:To identify and characterize one Yokenella regensburgei strain(designated as CXLZQ123) isolated from a case of perionychial abscess. Methods:Strain CXLZQ123 was isolated from a patient with periungual abscess at the Dermatology Department of San County Central Hospital in June 2, 2023. The strain was initially identified through morphological and biochemical tests, followed by mass spectrometry identification, 16S rRNA sequencing and whole-genome sequencing. MEGA 11.0 was used to compare and analyze the strain′s genetic relationship with relevant species in GenBank, and a phylogenetic tree was constructed based on genetic distance to analyze its genetic evolution. Meanwhile, the average nucleotide identity between its genome and similar strains were compared.Results:The strain was identified as a Gram-negative rod. MicroScan WalkAway biochemical tests indicated that the strain was either Yokenella regensburgei (91.47%) or Hafnia alvei (8.53%). MALDI-TOF mass spectrometry confirmed it as Yokenella regensburgei. Based on 16S rRNA gene sequence analysis, the strain showed the highest similarity(99.37%) to CIP 105435 (sequence number NR_104934.1). The 16S rRNA gene sequence of the isolated strain Yokenella regensburgei was submitted to the National Center for Biotechnology Information (NCBI) with the GenBank sequence number of OR230248.1. The whole-genome of CXLZQ123 were sequenced and uploaded (NCBI, SRA sequence number: SRR26510420). The average nucleotide identity between CXLZQ123 and Yokenella regensburgei strains W13 and UU2206353 were 98.82% and 99.04%, respectively. Conclusions:Through morphological observation, biochemical identification, mass spectrometry identification, 16S rRNA and whole-genome sequencing, this pathogenic strain is identified as Yokenella regensburgei. This rare bacterium is sensitive to most detected antibiotics. This study provides diagnostic and treatment experience for Yokenella regensburgei-related infections.

ObjectiveTo investigate the expression of lysophosphatidic acid （LPA） in patients with liver cancer， as well as its influence on malignant biological behavior of liver cancer and related regulatory mechanism. MethodsFrom January 2016 to December 2022， 26 patients with liver cancer， 28 patients with liver cirrhosis， and 28 individuals undergoing physical examination were enrolled. ELISIA was used to measure the content of LPA in plasma and peritoneal effusion of the patients with liver cancer or liver cirrhosis accompanied by peritoneal effusion， and the content of LPA was measured in plasma of the normal population at the same time， so as to clarify the difference in the expression of LPA in different populations， such as the patients with liver cancer and those with liver cirrhosis. MTT cell proliferation assay and cell migration assay were used to observe the influence of LPA and its inhibitor pertussis toxin （PTX） on the proliferation， migration， and invasion of SMMC7721 cells. In order to investigate the effect of LPA on the expression of RhoA and its upstream and downstream molecules FAK and P53 after binding to its receptor， qPCR and Western blot were used to observe the effect of LPA on the mRNA and protein expression levels of P53， FAK， and RhoA in SMMC7721 cells. A one-way analysis of variance was used for comparison of the means of continuous data between multiple groups， and the SNK-q test was used for comparison between two groups. ResultsCompared with the patients with liver cirrhosis， the patients with liver cancer had a significantly higher concentration of LPA in plasma （4.99±0.55 μmol/L vs 2.63±0.43 μmol/L， P<0.05） and peritoneal effusion （5.19±0.63 μmol/L vs 2.91±0.46 μmol/L， P<0.05）， and the patients with liver cancer also had a significantly higher level of plasma LPA than the normal population （4.99±0.55 μmol/L vs 1.61±0.39 μmol/L， P<0.05）. The cell proliferation assay showed that LPA significantly promoted the proliferation of SMMC7721 cells， and cell proliferation rate increased with the increase in dose and time； in particular， the middle-and high-dose groups had a significantly higher proliferation rate than the control group （P<0.05）. PTX inhibited the proliferative capacity of SMMC7721 cells in a time-dependent manner， and there was a significant difference between the groups （P<0.05）. The proliferation rate of the 72-hour high-dose LPA group was 3.6 times that of the control group， while the proliferation rate of the PTX group was 0.6 times that of the control group； the proliferation rate of the 72-hour high-dose LPA+PTX group was 1.2 times that of the control group. In addition， LPA increased the migration ability of hepatoma cells， while PTX inhibited their migration， in a time-dependent manner， and there was a significant difference between the groups （P<0.05）. The migration rate of the 72-hour high-dose LPA group was 3.09 times that of the control group， while the migration rate of the PTX group was 0.4 times that of the control group； the migration rate of the 72-hour high-dose LPA+PTX group was 0.99 times that of the control group. qPCR and Western blot showed that there were significant reductions in the mRNA and protein expression levels of P53 in SMMC7721 cells after LPA treatment， while there were significant increases in the mRNA and protein expression levels of FAK and RhoA； there was a significant difference between the LPA group and the control group （P<0.05）. ConclusionThere is an abnormal increase in the expression of LPA in patients with liver cancer， and LPA can promote the proliferation of liver cancer cells and increase their migration ability. At the same time， LPA changes the expression levels of P53， FAK， and RhoA， which may be associated with the promotion of tumor development and progression by LPA.

Objective To investigate the status of self‐management of blood pressure (BP) among elderly hypertensive patients living in new rural communities of Shanghai. Methods We enrolled a total of 2 241 hypertensive patients over 60 years old who participated in the National Key Research and Development Project "Cohort study on hypertension" of the 13th Five‐Year Plan in Langxia, Shanghai from May to July 2018. Questionnaires, physical examinations, and laboratory tests were conducted. We collected participants' demographic information, cardiovascular history, and self‐management behaviors related to hypertension. The status of self‐management of BP among participants with hypertension was analyzed. Pearson's chi‐squared test was used to explore the differences between males and females. Results Participants'mean age was (70.0±6.8) years, and males accounted for 38.8% of all participants. The systolic and diastolic BP levels of participants were (147.8±15.4) mmHg (1 mmHg=0.133 kPa) and (82.8±9.8) mmHg, respectively. The systolic blood pressure level of women was higher than that of men, and the diastolic blood pressure level of men was higher; the difference was statistically significant (all P<0.05). The awareness, treatment, and control rate of hypertension were 79.0%, 78.0%, and 25.6%, respectively. Males had a significantly higher control rate than females (P<0.05). The status of self‐management of blood pressure was as follows: (1) As to lifestyle, 84.4% of participants lacked exercise, and 69.2% were overweight or obese. The prevalence of smoking and drinking was higher in males (40.7% and 46.2%, respectively), and the proportion of females (12.4%) with anxiety and/or depression was higher than that of males (P all<0.001). (2) Concerning BP‐monitoring, only 10.1% of participants measured BP every week, 22.9% had BP measurement instruments at home, and 4.6% recorded their BP levels. There was no significant difference in self‐blood pressure monitoring behavior between men and women. (3) Regarding adherence to medication treatment, 97.6% took antihypertensive drugs regularly, and 21.6% were on combination therapy. The proportion of men taking combined drugs was higher than that of women, but there was no significant difference. Conclusions The rates of awareness, treatment, and control of hypertension in elderly hypertensive patients in new rural communities of Shanghai were above the national average. However, the status of self‐management of BP was still not satisfactory. More attention should be paid to healthy lifestyle, home BP monitoring, and effective pharmaceutical treatment strategies for hypertension.

Objective To explore the biomechanical properties of posterior occipital condyle screws compared with common occipitocervical fusion internal fixation and it's impacts upon stress of hypoglossal canals.Methods Finite element models based on the occipitocervical CT data of one 28-year-old male healthy volunteer were built,including normal model,instability model,internal fixation model by occipital condyle screws,internal fixation model by occipital plate screws,and internal fixation model by transarticular screws.Fifty N gravity and 1.5 N · m torque were exerted upon the surface of occipital bone so that the models could perform lateral bending,flexion,extension,and rotational motions.The motion range and stress distribution of internal fixation were compared under varying conditions among different occipitocervical fusion models.In addition,the impact of occipital condyle screw upon hypoglossal canals was examined.Results Compared with instability model,the motion range in the internal fixation model by occipital condyle screws declined by 96.8％,95.6％,95.0％ and 98.5％ respectively in lateral bending,flexion,extension and rotation.In the internal fixation by occipital plate screws,the motion range decreased by 96.3％,95.7％,98.4％ and 99.6％ respectively.In the internal fixation by transarticular screws,the motion range exhibited a decline of 95.7％,94.0％,94.3％ and 98.9％,respectively.The stress peaks in the occipital condyle screw were 192.4 MPa,201.6 MPa and 187.6 MPa under lateral bending,flexion,and rotation conditions,respectively.The stress peaks in the occipital plate screw were 279.6 MPa,213.7 MPa,and 154.1 MPa,respectively.The stress peaks in the transarticular screw were 232.4 MPa,220.9 MPa,and 224.5 MPa,respectively.The stress impact peak of occipital condyle screw on the hypoglossal canals wall was 12.96 MPa,and the content deformationunder the hypoglossal canal was 0.64％.Conclusions The occipital condyle screw internal fixation has similar stability with common occipitocervical fusion fixations.The occipital condyle screw has more uniform stress distribution and less effect on the hypoglossal canals,and hence is safe and reliable as anchor point on the cranial side in occipitocervical fusion.

Objective To investigate the safety of the occipital condylar screw with vertical position and evaluate the selection strategy of the posterior approach of the posterior occipital condylar screw in Chinese people.Methods The clinical imaging data of 60 outpatients from September 2013 to September 2015 were retrospectively analyzed,36 male and 24 female,the average age was 41.6±9.2 (range from 25-58),Excluded occipitocervical injury,tumor and deformity patients.We built a three-dimensional digital model and simulated placing screw by utilizing CT data on Mimics software,after that we took the occipital condyle posterior medial and lateral midpoint as the entry point,then made 2 points equidistantly to the midpoint in vertical direction.We put 3.5 mm diameter virtual screws in 4 different conditions:largest cranial angle,smallest cranial angle,longest screw path and shortest screw path.Then we assessed the anatomical relationship between the screw and the hypoglossal canal or the atlanto-occipital joint by a three-dimensional window and measured the cranial angle,medial angle and length of screw path,then calculated the safety angle of the cranial angle,the successful rate of setting screw,and compared the safety of different screw points by 3-Matic software.Results 120 occipital condyles were obtained from the CT data of 60 patients by Mimics software.There was no significant difference in the data of the cranial angle,medial angle,safety range and length between both left and right sides.The obtained safe cranial angle of each point respectively was 20.9°±6.0° (lowest point),17.0°±6.2° (middle point),and 11.6°±7.1°(top point),obviously the largest angle was in the lower point and the smallest was in the top point.The difference was statistically significant.We then acquired the successful rates of different cranial angle of each point,the highest successful rate was 99.17％,96.67％,74.17％ in lowest,middle and top point when cranial angle were 3°or 4°,3°and 0°respectively.The successful rates of lower point and niddle point were significantly higher than the top point,and the difference was statistically significant.The medial angle parameters obtained were 34.41°±2.59°on left and 34.06°±2.44°on right,and there was no significant difference.The length parameters of the longest screw path acquired were 23.09± 1.47 mm,22.84± 1.40 mm and 23.15± 1.45 mm at top,middle and lowest entry point.The average value of shortest screw path of each point was 21 mm,and there was no significant difference among every entry point.Conclusion Among the occipital condyle posterior screw entering points,selecting the lower point can improve the success rate and safety;the change of nail enter point in the vertical direction has little effect on the length of the nail.We can increase the safety and reduce the risk of occipital condylar screw placement as far as possible through the three-dimensional digital technology.

ObjectiveTo investigate the changes in the levels of serum adiponectin (APN) and serum ferritin (SF) in patients with nonalcoholic fatty liver (NAFL) and normal populations in Qinghai, China, as well as the significance of APN and SF in the pathogenesis of NAFL. MethodsA total of 39 patients diagnosed with NAFL in The Affiliated Hospital of Qinghai University from February to October, 2015 were enrolled as NAFL group, and 34 healthy individuals who underwent physical examination were enrolled as control group. The anthropometric parameters and routine clinical biochemical parameters were measured and enzyme-linked immunosorbent assay and chemiluminescence immunoassay were used to measure the levels of serum APN and SF. The independent-samples t test was used for comparison between two groups, and the Pearson correlation analysis was also performed. ResultsCompared with the control group, the NAFL group had a significantly higher level of SF (291.97±38.82 ng/ml vs 93.21±8.74 ng/ml, t=31.085, P＜0.001) and a significantly lower serum level of APN (11.91±2.88 mg/L vs 16.18±2.80 mg/L, t=6.383, P＜0.001). The correlation analysis showed that in the NAFL group, serum APN level was negatively correlated with TG level (r=-0.466, P＜0.01). ConclusionThe patients with NAFL in Qinghai have a reduced serum APN level and an increased SF level, and in these patients, serum APN level is negatively correlated with TG level. Serum APN monitoring may be used as a reference index to evaluate the treatment outcome of hypertriglyceridemia.
