ABSTRACT
Objective:To evaluate the clinical effectiveness of the reconstruction of multiple digit-tip defects with transfer of polyfoliate perforator flaps of the fibular hallux.Methods:From January 2019 to June 2022, 15 patients had undergone reconstruction surgery for multiple digit-tip defects using polyfoliate perforator flaps of ipsilateral fibular hallux, with the first dorsal metatarsal artery as the pedicle, in the Department of Upper Limb Repair and Reconstruction Surgery, Guizhou Hospital of Beijing Jishuitan Hospital. The patients were 10 males and 5 females and aged 20 to 45 years old. Eight patients had the defects of thumbs and index fingers, 4 of thumbs and middle fingers, 2 of thumb, index and middle fingers and 1 of thumb, index and ring fingers. All the 15 digit injuries had nail bed defects to which reconstructive surgery were required. For the flaps of dorsal artery, flaps were 1.8 cm×2.0 cm-2.0 cm×3.1 cm in size and for those of plantar artery, the flaps sized 1.5 cm×2.0 cm-2.5 cm×3.0 cm. Donor site defects in the hallux were reconstructed with free superficial circumflex iliac perforator flaps. Postoperative follow-up lasted until 30th June 2023 and included visits to the outpatient clinic, WeChat and telephone reviews to assess the appearance, function and sensation recovery of the digits.Results:All the 15 flaps survived. During the 6 to 24 months (16 months in average) of postoperative follow-up, the appearance and texture of all flaps were found close to the healthy digits, with good nail growth and without deformity. TPD were found between 8.0 mm and 12.0 mm. The donor sites on the great toes that reconstructed with superficial circumflex iliac artery flaps were all survived well, and the incisions were satisfactorily healed without the functions of walking, running or jumping being significantly affected.Conclusion:The use of polyfoliate perforator flaps of fibular hallux for reconstruction of multiple digit-tip defects is an ideal surgical method due to the consistency of vascular anatomy, ease with flap harvest, similarity in the normal digital skin texture, and the capability to include a nail bed with the flap. A single donor from the hallux can simultaneously reconstruct two defects of digit-tip, making it an excellent treatment in the reconstruction of small-to medium-sized composite tissue defects in multiple digits.
ABSTRACT
Objective@#To analyze the characteristics of influenza virus detection in an influenza outbreak in schools, so as to provide a strategic basis for the treatment of influenza outbreaks in schools.@*Methods@#A total of 1 702 samples were collected from 52 school influenza outbreaks reported in Linyi City in 2021-2022. The samples were divided into 3 types according to different symptoms during the management of the epidemic [group A:influenzalike illness (ILI) group; group B:mild illness group; group C:close contacts group]. Rt-PCR was used to detect influenza virus nucleic acid in the collected samples. The detection rate of influenza virus in the outbreaks was analyzed by χ2 test.@*Results@#In total, 1 071 samples (62.93%) tested positive for influenza virus nucleic acid. Among them, 610 out of 726 samples (84.02%) were detected in group A, while 331 out of 634 samples (52.21%) were detected in group B. In group C, 130 out of 342 samples (38.01%) tested positive. The differences were statistically significant (χ2=260.71, P<0.01). In group A, males had a detection rate of 80.83% for influenza virus nucleic acid, compared to 91.36% for females. For group B, the rates were 53.31% for males and 50.87% for females. In group C, males had a rate of 30.72%, while females had a rate of 43.92%. Statistical significance for gender differences was observed only in groups A and C (χ2=12.67, 6.25, P<0.05). According to the days of onset, the detection rates of influenza virus nucleic acid among patients with onset 0-6 days were 56.30%, 74.49%, 89.35%, 86.23%, 69.67%, 62.75%, 34.33%, respectively, and the difference was statistically significant (χ2=128.27, P<0.01).@*Conclusions@#Mild cases and close contacts are likely key factors contributing to the prolonged emergence of new cases within classrooms during school influenza outbreaks. The progression of influenza symptoms is related to the risk of transmission.
ABSTRACT
Objective:To investigate the stability of α-synuclein (α-Syn) aggregates formed by incubation with blood plasma of patients with Parkinson's disease (PD).Methods:Peripheral blood samples were collected from 10 patients diagnosed as having PD in our hospital from June 2020 to December 2020 and 10 healthy control subjects (HC) at the same time period. The 1 mg recombinant human α-Syn was dissolved in 140 μL 0.01 mol/L phosphate buffer solution (PBS), and then, incubated with plasma from HC and PD patients and PBS at 37 ℃ for 7 d (HC group, PD group and PBS group). Preformed fiber (PFF) group was used for subsequent experiment with 10 μg PFF. After digestion with different concentrations of trypsin (concentration ratios of trypsin/α-Syn=1:80, 1:40, and 1:20) and protease K (PK, 1.0, 1.5, and 2.0 μg/mL), the differences of α-Syn levels before and after digestion were detected by Western blotting.Results:(1) Effect of trypsin on PFF digestion: PFF gradually decreased with the increase of trypsin doses; when trypsin/α-Syn ratio=1:20, α-Syn aggregates with molecular weight greater than 35 000 were almost completely digested, and its digestion was significantly different as compared with that in other concentration ratios ( P<0.05). (2) Effect of trypsin on digestion of α-Syn aggregates: at the relative molecular weight<25 000, when the concentration ratio of trypsin/α-Syn=1:20, as compared with HC and PD groups, the PBS group had significantly more obvious decrease ( P<0.05). At the relative molecular weight 35 000-40 000, the α-Syn levels in PBS, HC and PD groups were significantly decreased as compared with those before digestion at all concentration ratios; as compared with HC and PD groups, the PBS group had significantly more obvious decrease ( P<0.05). At molecular weight>40 000, α-Syn decreased significantly in PD group only when the concentration ratio of trypsin/α-Syn=1:20, and the degrees of digestion was PBS group>HC group>PD group, with significant differences among groups ( P<0.05). (3) Effect of PK on PFF digestion: when PK concentration was 1.0, 1.5 or 2.0 μg/mL, α-Syn was basically digested at relative molecular weight>35 000, and α-Syn monomer was reduced and small fragment appeared at relative molecular weight<25 000; as compared with negative controls (0 μg/mL PK), these changes in groups of PK concentration of 1.0, 1.5 or 2.0 μg/mL were significantly different ( P<0.05). (4) Effect of PK on digestion of α-Syn aggregates: at relative molecular weight<25 000, α-Syn in PBS group was digested into smaller fragments while α-Syn in HC and PD groups was not digested; significant differences was noted among groups at the same concentration ( P<0.05). At relative molecular weight of 35 000-40 000, with the increase of PK concentration, the amount of α-Syn dimer in PBS group decreased (increased digestibility), that in HC group increased, however, that in PD group did not change obviously; significant difference was noted at the same concentration among the three groups ( P<0.05). At relative molecular weight>40 000, with the increase of PK concentration, α-Syn in PBS, HC and PD groups decreased to a certain extent, and significant difference was noted among groups at the same concentration ( P<0.05). Conclusion:The stability of α-Syn aggregates formed by incubation with plasma from PD patients is higher than that formed by incubation with HC plasma and PBS.
ABSTRACT
Objective@#To analyze the molecular characteristics of Listeria monocytogenes strains from ready-to eat food in China.@*Methods@#A total of 239 Listeria monocytogenes strains isolated from ready-to-eat food in 2017, all strains underwent whole-genome sequencing (WGS) , and comparisons uncovered population structure derived from lineages, clonal complex, serogroups, antimicrobial susceptibility and virulence, which were inferred in silico from the WGS data. Core genome multilocus sequence typing was used to subtype isolates.@*Results@#All strains were categorized into three different lineages, lineage Ⅱ was the predominant types in food, and IIa was the main serogroups. CC8, CC101 and CC87 were the first three prevalent CCs among 23 detected CCs, accounting for 49.4%. Only 4.6% (11 isolates) of tested strains harbored antibiotic resistance genes, which were mostly trimethoprim genes (7 isolates, 2.9%). All strains were positive for LIPI-1, and only a part of strains harbored LIPI-3 and LIPI-4, accounting for 13.8% (33 isolates) and 14.2% (34 isolates), respectively. ST619 carried both LIPI-3 and LIPI-4. 51.5% (123 isolates) of strains carried SSI-1, and all CC121 strains harbored SSI-2. Different lineages, serogroups and CCs can be separated obviously through cgMLST analysis, and 24 sublineages were highly concordant with CCs.@*Conclusion@#Ⅱa was the main serogroups in ready-to-eat food isolates in China; CC8, CC101 and CC87 were the prevalent CCs, and CC87 isolates was hypervirulent isolates, cgMLST method can be adopted for prospective foodborne disease surveillance and outbreaks detection.
ABSTRACT
Background and Objective: Spontaneous coronary artery dissection [SCD] remains a rare and important cause of coronary artery disease [CAD]. The purpose of this study was to describe the clinical and angiographic features in SCD and to evaluate the treatment and long-term prognosis of this condition in China
Methods: This retrospective cohort study included 118 Chinese patients with SCD confirmed by coronary angiography. Clinical and angiographic features, treatment modalities and outcomes of SCD were estimated
Results: The overall prevalence of SCD was 0.15%. Age was 57 +/- 10 years; 86% patients were men; 75% presented with acute coronary syndrome [ACS]; 72% had concomitant atherosclerotic CAD. SCD often affected right coronary artery [RCA] and caused a short dissection [< 20mm]. A conservative therapy was used in 28% of patients and revascularization in 72% [percutaneous coronary intervention [PCI] 57%; coronary artery bypass grafting [CABG] 15%]. Only one patient died during hospitalization due to multiple organ failure after CABG. During a median follow-up of 43 months [range, 1 - 158 months], 32 patients had a new-onset ACS, 9 received revascularization [7 PCI and 2 CABG], and 8 died. The Kaplan-Meier estimated 12-year rates of freedom from cardiac death and ACS were both higher in revascularization versus conservative therapy [78% versus 57%; P = 0.023; 48% versus 25%, P = 0.014]. No significant difference was found in freedom from revascularization between the two therapies
Conclusions: In China, SCD was usually associated with atherosclerosis and predominantly affected male population. SCD often affected RCA and caused a short dissection. In-hospital mortality rate was low regardless of therapeutic strategy. However, a significantly better long-term prognosis was observed in the revascularization compared with conservative therapy
ABSTRACT
Objective To analyze the homology, biofilm-forming ability, and risk factors of prevalent A, B, C clones(carrying blaOXA-23 and blaOXA-51 genes mostly) of carbapenem-resistant Acinetobacter baumannii (CRAB) relative to carbapenemsusceptible Acinetobacter baumannii (CSAB). Methods A total of 87 prevalent A, B, C clones of CRAB and CSAB strains were collected from the First Affiliated Hospital of Chongqing Medical University. Multilocus sequence typing (MLST) was used for homologyanalysis of clone A, B, C strains. Biofilm-forming ability of CRAB and CSAB was measured quantitatively via crystal violet staining. Results Clone A was measured to be homologous type of ST238, while clones B and C were ST238 type. In general, CRAB prevalent clones showed weaker biofilm-forming ability than CSAB strains (0.470±0.301 versus 0.913±0.626, P<0.05). CRAB clones A, B, and C varied in ability of biofilm formation. Clone A had comparative biofilm-forming ability to clone C (P=0.432). Both clone A and C were weaker than clone B in biofilm-forming ability (both P<0.001). Biofilm-forming ability was not associated with blaOXA-23 or blaOXA-51 genes in CRAB strains (both P>0.05). Conclusions Prevalent CRAB clone A, B, C are derived from the same origin. We are the first to report the prevalence of ST238 and the homologous types in a hospital. Biofilm-forming ability is negatively correlated with carbapenem resistance of Acinetobacter baumannii, which suggests that clone prevalence is mainly related to antibiotic resistance acquisition and antibiotic selective pressure. Biofilm-forming ability varies with the prevalent CRAB clone. The wide spread of clone B is of concern.
ABSTRACT
Objective To study the effect of levosimendan on cardiomyocyte apoptosis after coronary microembolization (CME) in swine,Methods Fifteen healthy swines were randomly divided into sham operation group,CME group and levosimendan treatment group (5 in each group).Their cardiac function was assessed by echocardiography,their cardiomyocyte apoptosis was assyed with TUNEL staining,and Caspase-3 expression was detected by Western blot at 12 h after operation.Results The LVEF was lower,the left ventricular minor axis was shorter and the cardiac output volume was smaller while the LVEDD was longer in CME group than sham operation group (P<0.05).The cardiac function was significantly better in CME group than in sham operation group (P<0.05).The cardiomyocyte apoptosis rate and Caspase-3 expression level were significantly higher in CME group than in sham operation group (P<0.05).The cardiomyocyte apoptosis rate was significantly higher while the Caspase-3 expression level was significantly lower in levosimendan treatment group than in CME group (6.820%±-1.974 % vs 10.558%±2.425%,P<0.05).Conclusion Pretreatment with levosimendan can effecively reduce the cardiomyocyte apoptosis and improve the cardiac function after CME by inhibiting the Caspase-3 expression in cardiomyocytes.
ABSTRACT
Objective@#To examine the regulatory effect of ginsenoside Rg1 (G-Rg1) on endoplasmic reticulum stress and its effect on hepatocellular apoptosis in carbon tetrachloride (CCl4)-induced acute liver failure (ALF).@*Methods@#Forty healthy, adult male C57/BL mice were randomly divided into normal saline control (NS) group, G-Rg1 blank control (G-Rg1) group, CCl4 model (CCl4) group, and G-Rg1 preventive treatment (CCl4+G-Rg1) group, and an ALF mouse model was established by CCl4 induction. Blood and liver specimens were collected from all mice upon sacrifice at 12 hours post-intraperitoneal injection. Serum alanine aminotransferase (ALT), serum aspartate aminotransferase (AST) and total bilirubin (TBil) levels were determined using commercial test kits. The mRNA expression of glucose-regulated protein 78 (GRP78) and C/EBP homologous protein (CHOP) was measured using real-time PCR. The protein expression of GRP78, CHOP, caspase12, and caspase3 were measured by Western blot. Histological changes in the liver were assessed by hematoxylin-eosin staining, and the expression of GRP78 and caspase3 was detected by immunohistochemistry. Hepatocyte apoptosis was determined using terminal transferase dUTP nick end labeling. Quantitative data were analyzed using one-way ANOVA, and subsequent pairwise comparisons were performed using the LSD-t method.@*Results@#Serum ALT, AST, and TBil levels in the CCl4+G-Rg1 group were significantly reduced compared with those in the CCl4 group (ALT: 691.30 ± 108.06 U/L vs 980.66 ± 110.29 U/L, F = 365.07, P < 0.05; AST: 195.40 ± 15.41 U/L vs 319.44 ± 89.32 U/L, F = 115.64, P < 0.05; TBil: 1.09 ± 0.11 mg/dl vs 1.56 ± 0.12 mg/dl, F = 211.29, P < 0.05). The relative mRNA expression of GRP78 and CHOP was significantly lower in the CCl4 + G-Rg1 group than in the CCl4 group (P < 0.05). The relative protein expression of caspase3, GRP78, caspase12, and CHOP was significantly reduced to different extents in the CCl4+G-Rg1 group compared with those in the CCl4 group (P < 0.05). The CCl4 + G-Rg1 group showed reduced liver tissue degeneration and necrosis compared with the CCl4 group. Furthermore, the CCl4+G-Rg1 group showed significantly fewer brown granules in the liver than the CCl4 group (P < 0.05), indicating that G-Rg1 preventive treatment reduced CCl4-induced hepatocyte apoptosis.@*Conclusion@#G-Rg1 prophylaxis can inhibit inflammation and reduce hepatocyte necrosis and apoptosis during CCl4-induced ALF. Its mechanism may involve the suppression of endoplasmic reticulum stress-related signaling molecules to alleviate hepatocyte endoplasmic reticulum stress and apoptosis. The results of this study suggest that G-Rg1 may inhibit liver inflammation and hepatocyte apoptosis through multiple targets to protect liver function.

ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Rgl treatment on prognosis of alcoholic hepatitis using a rat model.</p><p><b>METHODS</b>Female Sprague-Dawley rats were radomly divided into four groups:unmodeled control, untreated model, Rgl-treated model, and dexamethasone (DXM)-treated model. The model groups were generated by intragastric injection of alcohol. The unmodeled control group was given an equal dosage of normal saline by the same route. After model establishment, the Rg1 treatment group and the DXM treatment group were administered a 120-hour treatment of Rgl or DXM; the unmodeled controls were administered normal saline on the same schedule. All rats were then fasted for 120 hours and venous blood samples were collected for detection of serum aspartate aminotransferase (AST), alanine transaminase (ALT), total bilirubin (TBil), albumin (Alb), tumor necrosis factor-alpha (TNFat) and interleukin 6 (IL-6). Markers of liver inflammation were measured by immunohistochemistry, western blotting, and real-time quantitative reverse transcription PCR. Fat and apoptosis indices were assessed by hematoxylin-eosin staining and TUNEL assay, respectively. The t-test and F test were used for statistical analyses.</p><p><b>RESULTS</b>The model group showed remarkably more liver steatosis (over one-third of the tissue) than the unmodeled control group, indicating proper establishment of alcoholic liver disease in the modeled rats. The AST, ALT, TBil, and IL-6 levels were significantly higher in the untreated model group than in the Rgl-treated group and the DXM-treated group. The values were significantly different between the Rg1-treated group and the DXM-treated group:ALT, 69.19+/-8.00 U/L vs.102.88+/-5.16 U/L; TBil, 0.36+/-0.07 µmol/L vs.1.20+/-0.18 µmol/L; IL-6, 126.50+/-6.50 U/ml vs.169.19+/-7.68 U/ml; TNFa, 268.31+/-13.19 µg/L vs.318.94+/-7.87 µg/L (all P less than 0.05). Expression of caspase3 and caspase8 was significantly higher in the model group than in the Rgltreated group and the DXM-treated group (both P<0.05). The apoptosis index was significantly lower in the Rgltreated group and the DXM-treated group than in the model group (both P<0.05). The mRNA and protein expression of caspase3, caspase8 and NF-kB were significantly lower in the Rgl-treated group and the DXM-treated group than in the model group (allP less than 0.05), and the levels of all were significantly lower in the Rgl-treated group cornered to the DXM-treated group (all P<0.05). Conehision In rats with alcoholic hepatitis, Rg1 can significantly relieve pathological injury, improve liver function by blocking the apoptotic pathway, and inhibit release of inflammatory cytokines.</p>

BACKGROUND:The key difference between closed reduction and open reduction for femoral neck fracture is the incision of joint capsule or not. As for this problem, scholars have different opinions, but there is no unified conclusion. OBJECTIVE:To compare reduction quality and the rate of femoral head necrosis of open reduction and closed reduction in the treatment of femoral neck fracture in middle-aged and young patients with displaced femoral neck fracture. METHODS: Clinical data of 102 middle-aged and young patients with femoral neck fracture, who were treated in the Department of Traumatic Orthopedics, Guizhou Orthopedic Hospital from June 2008 to June 2014, were analyzed. They were folowed up. According to the manner of reduction, they were divided into open reduction group (n=39) and closed reduction group (n=63). General data, postoperative fracture healing, the rate of femoral head necrosis and reduction quality were compared between the two groups. RESULTS AND CONCLUSION:No significant difference in general information, preoperative and postoperative hemoglobin difference, fracture healing time and fracture nonunion rate was detected between the two groups (P > 0.05). The rate of femoral head necrosis was lower in the open reduction group than in the closed reduction group, but reduction quality was higher in the open reduction group than in the closed reduction group (P < 0.05). These results indicate that in the treatment of displaced femoral neck fractures in middle-aged and young patients, postoperative femoral head necrosis rate of open reduction and fixation is low, and the quality of reduction is better. Open reduction has a certain advantage, but the case number and case study have a certain limitation. We should choose the appropriate way of operation treatment according to the patient’s condition.

Objective:This study aims to evaluate the clinical effect and adverse reactions of oxaliplatin or irinotecan plus capecitabine treatment for colorectal liver metastases. Methods:Data from 125 cases of colorectal liver metastasis patients were continuously enrolled and randomized into two groups, i.e., 63 in group one (treatment group) and the other 62 in group two (the control group). Capecitabine was administered at 1 000 mg/m2 doses, twice a day from d1 to d14, to all patients. Irinotecan was administered at 150 mg/m2 in d1 to group one, and oxaliplatin was administered at 130 mg/m2 in d1 to group two. The drug administration cycle lasted for 21 days in both regimens, with at least 6 administration cycles. The total course was for 6 months at most. The therapeutic efficacy, median progression-free survival time, median survival time, short-term clinical effect, and adverse drug reaction were monthly determined. Results:The overall response rates and disease control rates were 33.3%and 66.7%in group one, respectively, and 35.5%and 70.9%in group two, respectively, with no significant differences between the groups (P>0.05). The median survival time and median progression-free survival time were 14 months and 5 months in group one, respectively, and 12 months and 5 months in group two, with no significant differences between the two groups (P>0.05). The level-Ⅲand-Ⅳadverse drug reactions mainly include hematological toxicity, gastrointestinal reactions, and hand-foot syndrome. The diarrhea frequency is obviously higher in group one than in group two, and the difference between the two groups is sta-tistically significant (P0.05). Conclusion:The Oxaliplatin or Irinotecan plus Capecitabine treatment is effective for colorectal liver metastases, which enhances survival rate and reduces patient suffering because of it has less side effects and good tolerance. The treatment must be further generalized and clinically applied.
ABSTRACT
Objective To discuss the risk factors of free wall rupture (FWR) in acute ST-segment elevation myocardial infarction (STEMI) patients. Methods We retrospectively reviewed all patients (n=1247) with STEMI hospitalized in CCU from January 2005 to July 2010. Results FWR occurred in 29 patients(2.3%). Of these 1247 patients, 128 (10.2%) patients received thrombolytic therapy, 623 (50.0%) patients underwent primary PCI. Compared to No-FWR group, FWR group has signiifcant differences in age (62.4±6.4 y vs. 66.6±8.3 y, P0.05), diabetes mellitu (55.2%vs. 23.5%, P=0.022), presence of heart failure on admission (Killip≥Ⅱ) ( 16.4%vs. 34.0%, P 100 mg/L) and thrombolytic therapy were independent risk factors of FWR. Conclusions STEMI patients with advanced age, Killip≥Ⅱ, hCRP and thrombolytic therapy were more vulnerable of FWR.
ABSTRACT
Objective To observe the clinical effect of percutaneous vertebroplasty f PVP)and percutaneous kyphoplasty(PKP)in the treatment of ostcoporotic vertebral compressive fracture. Methods Forty-two patients with osteoporotic vertebral compressive fractures were treated with PVP or PKP from August 2007 to July 2009.VAS and SF-36 scoring systems were employed to evaluate the Dain and quality of life.X-ray was used to evaluate the vertehral height restoration rate and the kyphosis correction rate.The bone cement leakage was determined based on the Chest X-ray. Results There was staitistical difference on PMMA leakage between PVP and PKP group.VAS and SF-36 scores at 2 wePks and 6months after operation were much better than those counted before operation in both PVP and PKP groups(P<0.05).The VAS and SF-36 scores at 6 months after operation showed no statistical difference in comparison with those before operation between PVP and PKP groups(P>0.05).At tWO weeks after operation,the height restoration rate of the fractured vertebral body(anterior and central column)in the PKP group waa better than that in the PVP group(P<0.05).The kyphotic correction rate in the PKP group was a little better than that in the PVP group(P>0.05).Conclusions In the treatment of osteoporotic vertebral compressive fracture,PVP and PKP have the similar effect on the pain relief,can refresh the height of the fractured vertebral body and correct the kyphotic angel of the fracture level to some extent.PVP has more PMMA leakage than PKP.
