Objective To investigate the vaginal microbilme characterization in women with human papillomavirus(HPV)16 and 18 infection and high-grade cervical intraepithelial neoplasia(CIN).Methods Three groups were set,including control group(without HPV infection and with colpitis),low-grade CIN group(with HPV 16 or/and 18 infection),and high-grade CIN group(with HPV 16 or/and 18 infection).Virginal microbial composition was determined by using 16S rRNA amplication sequencing and hierarchical clustering analysis among three groups was applied.Rank sum test was used to determine statistical significance.Results Diversity and complexity of bacteria was significantly elevated in high-grade group.Compared with the control,the growth of Lactobacillus crispatus(L.crispatus) and Lactobacillus casei(L.casei) was significantly decreased,while Lactobacillus iners(L.iners) was significantly increased in low-grade CIN group and high-grade CIN group,and both were proportionally correlated to the grade of the disease.Brucella canis(B.canis),as colonized bacteria,was significantly decreased in both low-grade and high-grade CIN groups,and the changes were proportional to the grade of disease.The growth of Dialistersuccinatiphilus(D.succinatiphilus),Gardnerella vaginalis(G.vaginalis) and Prevotellabivia(P.bivia) were significantly elevated and proportional to the grade of disease.Conclusion The diversity and complexity of virginal microbial composition could be significantly expanded in women with HPV infection and high-grade CIN.In contrast to the important role of lactobacillus in virginal health,L.inners could be pathogenic.The colonization of B.canis,D.succinatiphilus,G.vaginalis and P.bivia might be highly correlated with HPV chronic infection and further development of CIN.

Objective To evaluate the effect of recombinant human annexin A5 on the expression of phosphorylated protein kinase C alpha (p-PKCα) and p120-catenin during endotoxin-induced damage to cardiomyocytes.Methods H9c2 cells cultured in vitro were randomly divided into 3 groups (n=18 each) using a random number table:control group (group C),endotoxin group (group L),and recombinant human annexin A5 group (group A).Recombinant human annexin A5 (final concentration 5 ng/ml) was added,and the cells were incubated for 2 h in group A,and then lipopolysaccharide (final concentration 1 μg/ml) was added,and the cells were incubated for 4 h in L and A groups.At 4 h of incubation,cell apoptosis was detected using the cell apoptosis detection kit,the intercellular space was measured using the confocal microscopy,and the expression of p-PKCα and p120-catenin was determined by Western blot.The apoptosis rate was calculated.Results Compared with group C,the apoptosis rate was significantly increased,the intercellular space was significantly widened,the expression of p120-catenin was significantly down-regulated,and the expression of p-PKCα was significantly up-regulated in group L (P＜0.05).Compared with group L,the apoptosis rate and intercellular space were significantly decreased,the expression of p120-catenin was significantly up-regulated,and the expression of p-PKCα was significantly down-regulated in group A (P＜0.05).Conclusion Recombinant human annexin A5 can inhibit phosphorylation of PKCα and up-regulate the expression of p120-catenin,thus attenuating endotoxin-induced damage to cardiomyocytes.

Objective To explore the influence of different injection techniques on the quality of bolus in 99mTc-DTPA renal dynamic imaging.Methods 395 patients accepted 99mTc-DTPA renal dynamic imaging were retrospectively analyzed.All patients were divided into three groups according to injection techniques:direct injection group (187 cases),intravenous route injection group (84 cases)and venous indwelling needle injection group (124 cases).The three groups were injected by each technique.Areas of interest (ROI) were drawn on abdominal aorta by Xeleris workstation in blood flow perfusion imaging.The time-radioactivity curves of ROI were got.The patients whose ROI curve formed a peak was successfully injected,and did not formed was unsuccessfully injected.The number of patients in three groups who were successfully or unsuccessfully injected was respectively calculated.The data of three groups was taken Chisquare test by SPSS17.0 software.Results 174 patients of the direct injection group,46 of the intravenous route injection group and 115 of the venous indwelling needle injection group were injected successfully.The successful rate respectively was 93.0％,54.8％ and 92.7％.The successful rate of the direct injection group and venous indwelling needle injection group were higher than intravenous route injection group.The difference had statistical significance.The successful rate of the direct injection group and venous indwelling needle injection group hadn't statistical significance.Conclusions The successful rates of the direct injection group and venous indwelling needle injection group were similar.The venous indwelling needle injection technique can be chosen.The successful rate of the intravenous route injection group was lower than the other two groups.The intravenous route injection technique should be chosen prudently.

Objective:To observe the pathological changes of levator palpebrae superiors muscle in patients with different severities of simple congenital ptosis (SCP).Methods:Levator palpebrae superiors muscle specimens from 102 eyes of 68 patients with SCP who received levator palpebrae superiors muscle shortening surgery at Wuhan Aier Hankou Eye Hospital from August 2018 to October 2019 were collected as the observation group.According to the severity of ptosis, the specimens were divided into three groups, coverage ≤4 mm group (n=35), coverage >4 mm to ≤6 mm group (n=30), and coverage >6 mm group (n=37). Fresh levator palpebrae superiors muscle tissues from 8 normal donors in Aier Eye Bank of Wuhan Red Cross were selected as the control group.All specimens were performed with Masson trichrome staining and immunohistochemical staining for α-smooth muscle actin (α-SMA), and ImageJ software was used to measure the collagen fiber area ratio, skeletal muscle fiber area ratio and the integrated absorbance (IA) value of α-SMA.Seventeen specimens (2 from the control group, 5 from coverage ≤4 mm group/coverage >4 mm to ≤6 mm group/coverage >6 mm group) were observed with a transmission electron microscope (TEM). This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Wuhan Aier Hankou Eye Hospital (No.HKAIER2018IRB-005-01). All patients and their legal guardians were well informed about the treatment method and the purpose of sampling and voluntarily signed informed consent.Results:Compared with the control group, the skeletal muscle fiber was reduced in number and was in disordered arrangement, and the striation of some muscle fibers disappeared, and hyperplastic fibrous connective tissue was found in intercellular substances in the observation group.The collagen fiber area ratio of the coverage ≤4 mm group, coverage >4 mm to ≤6 mm group, coverage >6 mm group were significantly higher than that of the control group, and the skeletal muscle fiber area ratio of the three groups was significantly lower than that of the control group (all at P<0.008 3). There were more smooth muscle fibers and positive expression of α-SMA found in the specimens of the observation group.The IA value of α-SMA of the coverage ≤4 mm group, coverage >4 mm to ≤6 mm group, coverage >6 mm group was 7 195.28(5 935.69, 14 058.29), 55 584.18(33 861.88, 80 419.32), 166 507.76(119 121.95, 187 890.86), respectively, which were all higher than 5 543.03(4 867.67, 8 312.02) of the control group, among which, there were statistically significant differences between the control group and the coverage >4 mm to ≤6 mm group, coverage >6 mm group (both at P<0.008 3). Abundant organelles and some damaged mitochondria were found in smooth muscle cytoplasm in the observation group with a TEM.But no characteristic structure of smooth muscle cells such as dense patch and dense body was detected.Conclusions:There are abnormal smooth muscle cells in the levator palpebrae superiors muscle of SCP patients, and the dysgenesis of the levator palpebrae superiors muscle may be related to this abnormal muscle cell.

Objective:To explore the effect of sliding tarso-conjunctival flap combined with allogeneic scleral transplantation for one-stage reconstructing posterior eyelid defect.Methods:The clinical data of eyelid tumor patients who admitted to Hankou Aier Eye Hospital from January 2015 to March 2019 were selected. The lesions crossed the gray line and the tarsal plates were involved. The benign tumor was removed from the margin by 1—2 mm and the pathological examination was performed. Mohs method (intraoperative delivery of frozen sections to control the cut edge) resection was performed for malignant tumor. The residual tarsal plate in the vertical direction after tumor was removed (upper eyelid≥3 mm, lower eyelid ≥2 mm) . The posterior defect reconstruction was performed by sliding the residual tarsal conjunctival flap to the eyelid margin, and the posterior tarsal defect area was repaired with allogeneic sclera. The anterior defect was reconstructed with sliding flaps, rotating flaps and free skin grafts.Results:A total of 8 cases were selected, including 3 males and 5 females, aged 31—76 years, with an average of 42 years old. 2 cases of eyelid intradermal nevi, 1 case of eyelid basal cell carcinoma, 4 cases of eyelid adenocarcinoma, and 1 case of eyelid squamous cell carcinoma. All patients were followed up for 6 to 24 months. All of the 8 patients had no tumor recurrence. Except for the absence of eyelashes in the reconstructed area, the eyelids were in good shape. Patients did not complain about foreign body sensation. No allogeneic sclera dissolution or rejection.Conclusions:For the residual tarsal plate in the vertical direction after tumor resection (upper eyelid≥3 mm, lower eyelid≥2 mm). The use of the sliding tarso-conjunctival flap combined with allogeneic scleral transplantation to reconstruct the posterior layer of the eyelid defect can achieve satisfactory result in both appearance and function.
