This study was aimed to observe the promotion effect of wound healing retention enema for postoperative anal fistula by modifiedWu-Wei Xiao-Du(WWXD) decoction, in order to explore its mechanism. A total of 60 patients who met the inclusion criteria were randomly divided into the treatment group and control group, with 30 cases in each group. Patients in both groups were diagnosed as simple low anal fistula and treated with low anal fistula incision. The retention enema of 30 mL modified WWXD decoction or complexHuang-Bai fluid were given once a day for postoperative dressing changes. Detailed observations and scores were made on wound exudate, color, and itching around the anus. The comparisons were made on carrion off time, new epithelium time, rate of wound-reducing, wound healing time, and the total clinical efficacy 21 days after operation. The results showed that the wound exudate on the 7th and 14th postoperative day was better than that of the control group. There was no significant difference on the 21st day between two groups. The wound color of the treatment group was better than that of the control group on the 7th and 14th postoperative day. The itching around anus of the treatment group was better than that of the control group on the 7th, 14th and 21st postoperative day. The carrion wound off time and new epithelium time of the treatment group were earlier than that of the control group. There was no significant difference on the rate of wound-reducing. There were no significant differences on the total clinical efficacy 21 days after operation as well as the total average healing time of both groups. It was concluded that modified WWXD decoction can shorten the inflammation phase, reduce the wound exudate and itching, promote early carrion fall and as well as the wound healing.

Objective To explore the effect of different proportions of mixed blood exchange transfusion on blood circulation in neonates with hemolytic disease.Methods Thirty-one newborn infants with hemolytic disease were treated by peripheral arteriovenous synchronization of exchange transfusion with different proportions mixed blood.AB type plasma was mixed with O type red blood cell(RBC) washing.The proportion for the treatment group was 1:1(the O type RBCs 2 U:the AB type plasma 200 mL),by exchange transfusion of haplotypes,in accordance with 80?mL/kg;the proportion for control group was 2:1(the O type RBC 4 U:the AB type plasma 200 mL),by exchange transfusion of double in accordance with 150-180 mL/kg.The indicators were detected,such as the exchange rate of neonatal serum bilirubin,RBC,hemoglobin(Hb),hematocrit(HCT),and the exchange transfusion quantity and days of hospitalization before and after the exchange transfusion were analyzed.Results The exchange rate of serum bilirubin of treatment group and control group was (44.92?3.99)% and (45.69?5.06)%,respectively,there was no significant difference between 2 groups(P=0.639),there was no significant difference of hospitalization days[(8.13?1.13) d vs(8.19?0.91) d]between 2 groups(P=0.884).After exchange transfusion in treatment group,the average level of the RBC,Hb and HCT were increased(P

Objective To explore the expression of HCK gene during the cardiomyocyte differentiation of mouse embryonic stem cells and analyze the role of HCK gene in maintenance of pluripotency of embryonic stem cells.Methods Mouse embryonic stem cells were cultured,then induced to differentiate into cardiomyocytes.Total RNAs were isolated from mouse embryonic stem cells in the differentiation days:0 day(D0),the second day(D2),the fourth day(D4),the sixth day(D6),the eighth day(D8),respectively.The levels of HCK mRNAs were assessed by the method of semi-quantitive reverse transcriptase-polymerase chain reaction(RT-PCR).In the meanwhile,Total proteins were also isolated from mouse embryonic stem cells in the differentiation D0,D2,D4,D6,D8,and the levels of HCK proteins were evaluated by Western-blot.Results HCK mRNAs could be detected in the mouse embryonic stem cells in D0 and D2,however,they were undetectable from D4 to D8.The expression of HCK mRNAs was rapidly down-regulated during cardiomyocyte differentiation of mouse embryonic stem cells.Expression of HCK proteins,which coincided with HCK mRNAs,down-regulated during differentiation and couldn't be detected in D4.Conclusions With the cardiomyocyte differentiation of mouse embryonic stem cells,the expression of HCK in the levels of mRNA and proteins are sharply down-regulated;HCK may play an important role in maintaining the pluripotency of embryonic stem cell.

Objective To detect the mutations of ATP2C1 gene in patients with Hailey-Hailey dis- ease (HHD).Methods PCR and direct sequencing were performed in 17 patients and 120 healthy controls to screen the mutations in the exons of ATP2C1 gene.Results Eight mutations were identified in nine probands, including three deletion mutations (nt1464-1487 del/nt1462-1485del,1523delAT,2375delTTGT),three splice site mutations (360—2A→G,1415—2A→T,2243+2T→C) and two missence mutations (C920T and G1942T).None of the above mutations was found in the controls.Conclusion Eight specific novel mutations were identified in nine probands of HHD,which could be causative factors of the disease.

Objective To investigate the change of plasma visfatin level and the relationship of plasma visfatin level to body mass index(BMI),waist hip ratio(WHR),blood glucose,plasma insulin levels as well as other factors in the subjects with different glucose tolerances.Methods Fasting and glucose loading 2 h plasma visfatin levels were assayed by ELISA in patients with type 2 diabetes and impaired glucose tolerance(IGT),and controls.The relationship of plasma visfatin level with BMI,HOMA-IR,blood lipids,plasma glucose,plasma insulin,free fatty acids(FFA)levels were also analyzed.Results Fasting and glucose loading 2 h plasma visfatin levels in the type 2 diabetic patients were significantly reduced compared with controls[(11.63?7.48)?g/L vs (16.82?6.06)?g/L and (12.02?6.86)?g/L vs (16.26?7.78)?g/L,both P＜0.05],and the level of plasma visfatin in IGT was lower than that in diabetics and higher than controls.The level of visfatin in obese subjects was modestly higher than that in non-obese subjects,but the difference is not significant.Plasma visfatin level was positively correlated with WHR(r=0.42,P＜0.01),and negatively with 2 h plasma glucose after glucose loading(2hPG)and HbA_(1C)(r=-0.33,P＜0.01 and r=-0.25,both P＜0.05).Multiple regression analysis showed that fasting plasma glucose,WHR,2hPG,high density lipoprotein cholesterol and HbA_(1C) were independent related factors in influencing plasma visfatin levels.Conclusion The change of visfatin level is associated with glucose metabolism,which may contribute,in part,to the pathogenesis of diabetes and obesity.

AIM: To observe thickness and morphological changes of bulbar conjunctiva pre- and post epidemic hemorrhagic conjunctivitis ( EHC ) therapy by optical coherence tomography ( OCT) .
METHODS: Observed morphological changes and measured the bulbar conjunctiva thicknesses of 29 cases (36 eyes) of incipient (1-2d) EHC patients, who were received and treated by department of ophthalmology, the Putuo Affiliated Hospital of Shanghai University of Traditional Chinese Medicine from May 2013 to December 2013, by OCT. Then measured the thickness again on 7, 14d after the therapy.
RESULTS: Among 29 patients (36 eyes), 7d after the EHC therapy, in 27 cured eyes, the full-thickness ( before 344. 00±59. 91μm, after 230. 19±22. 16μm, t=11. 75, P<0-01); epithelial thickness ( before 56. 52±6. 19μm, after 51. 37±5. 53μm, t=4. 61, P<0. 01); and stromal thickness (before 287. 11±60. 56μm, after 178. 81±20. 20μm, t=10. 69, P<0. 01) of patients' bulbar conjunctiva were thicker than values measured after therapy with significant difference. Significant difference was also found for full-thickness ( before 361. 39±65. 56μm, after 233. 44±22. 57μm, the difference was statistically significant, t=14. 45, P<0. 01);epithelial thickness ( before 55. 50±6. 72μm, after 46. 67±5-24μm, t=10. 06, P<0. 01) and stromal thickness ( before 305. 61±66. 02μm, after 186. 78±21. 82μm, t=13. 11, P<0-01 ) of patients' bulbar conjunctiva between values measured before and 14d after therapy.
CONCLUSION: The OCT is able to measure the thickness of bulbar conjunctiva in EHC patients. An significant increase was found in full, epithelial and stromal thickness of EHC patients' bulbar conjunctiva. With recovery from the disease, subepithelial fluid, interlaminar fluid and edema of the bulbar conjunctival stroma faded away firstly, which provide references for clinical therapies of the EHC.

Objective To compare the clinical efficacy and pregnancy outcomes of CO2 laser and loop electrosurgical excision procedure(LEEP)surgery in the treatment of cervical high-grade squamous intraepithelial lesion(HSIL)in women of childbearing age.Methods Patients with cervical HSIL of appropriate reproductive age(20-34 years old)who underwent satisfied colposcope,subsequently treated with laser or LEEP between Jan 2019 and Dec 2021 in Obstetrics and Gynecology Hospital,Fudan University were collected.All the patients were interpreted as transformation zone(TZ)type 1/2,and colposcopy biopsy diagnosed as cervical high-grade squamous intraepithelial lesion(HSIL)and received laser or LEEP according to the physician's advice and the patient's wishes.The effectiveness of the two surgeries was evaluated,and postoperative cytology,HPV result,and colposcopic pathology were compared.We monitored the surgical pregnancy rate,pregnancy complications,and pregnancy results after the surgery.Results A total of 566 cases,including 233 laser cases and 333 LEEP cases,were enrolled.There was no significant difference between the two groups in terms of preoperative cytology,HPV distribution,or the length of cervical canal.After 6 months of surgery,91.5%of patients who underwent laser therapy and 86.9%of those who underwent LEEP had normal cytology.The histology cure rate was 91.5%and the HPV conversion rate was 74.6%in both groups.The results of cytology,HPV,and colposcopic pathology had no significant difference between the two groups.The length of postoperative cervical canal was significantly longer in laser group than that in LEEP group[(29.09±3.15)mm vs.(27.05±3.84)mm,P<0.001].There was no statistically significant difference in postoperative pregnancy rate and pregnancy outcome between the two groups.Conclusion Laser ablation and LEEP produce comparable effects pregnancy outcomes in cervical HSIL patients with TZ types 1 and 2,while LEEP has pathologic feedback,so its misdiagnosis of invasive cancer reduce.

OBJECTIVEThis study aimed to explore the effects of hyperoxia on the development of fetal lung by investigating the changes of morphological and cell proliferation induced by hyperoxia in cultured fetal lungs as well as the effects of dexamethasone on hyperoxia-exposed lungs.

METHODSHuman fetal lung explants at the pseudoglandular stage of development were cultured randomly either in normoxia (21% O2/5% CO2) or hyperoxia (95% O2/5% CO2) for 72 hrs. Dexamethasone was added into the feeding medium at the concentration of 10(-6)M. Harvested tissues were stained for pancytokeratin to identify epithelial cells, with Ki-67 as a marker of proliferation. The effects of lung morphometry were analyzed using computer assisted image analysis. The mean airway thickness, the proportion of the surface area occupied by airways, the mean airway surface area and the index of the epithelium proliferation were measured.

RESULTSThe lung architectures remained unchanged after 72 hrs normoxia culture, whereas hyperoxia culture resulted in significant dilation of airways and thinning of epithelium, with the surface area of airways of 6662 microm(2) vs 2728 microm(2) and the thickness of airways of 7.8 microm vs 8.1 microm (P < 0.05). Hyperoxia culture also resulted in an increase in the proportion of the surface area occupied by airways than normoxia culture (35.2% vs 23.4%; P < 0.05). The surface area of airways (3174 microm(2)) and the proportion of the surface area occupied by airways (23.9%) decreased significantly in hyperoxia-cultured lungs after dexamethasone administration (P < 0.05). The epithelium proliferation index in hyperoxia-cultured lungs (21.8%) was higher than that in normoxia-cultured lungs (5.1%) and dexamethasone-treated hyperoxia-cultured lungs (7.4%) (P < 0.05).

CONCLUSIONSThe exposure of pseudoglandular lungs to hyperoxia modulates the lung architecture to resemble saccular lungs with higher epithelium proliferation index. Dexamethasone may inhibit the effects induced by hyperoxia.
