OBJECTIVES: To compare the efficacy of toric implantable collamer lens (Toric-ICL) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for myopia correction in patients with moderate to high myopia complicated with astigmatism. METHODS: We retrospectively collected data from 64 patients (aged 18-42 years) with moderate to high myopia complicated with astigmatism (128 eyes) undergoing either Toric-ICL (28 patients/56 eyes) or FS-LASIK (36 patients/72 eyes) at our department between January, 2019 and December, 2020. The changes of uncorrected distance visual acuity (UCVA), spherical equivalent (SE), mean astigmatism correction index (CI), corneal endothelial cell density (ECD) and intraocular pressure (IOP) following the procedures were compared between the two groups. RESULTS: In FS-LASIK group, all the eyes (72/72) achieved an UCVA≥1.0, similar to the rate in Toric-ICL group (55/56 eyes; P=0.2374). The postoperative SE was also comparable between FS-LASIK and Toric-ICL groups [0.43±0.06 D (range: -1.0 to 1.50 D) vs 0.38±0.05 D (range: -0.75 to 1.00 D); P=0.56]. The mean astigmatism CI was significantly higher in FS-LASIK group than in Toric-ICL group (0.8561 vs 0.7176; P<0.0001), and 88.89% of the eyes in FS-LASIK group and 69.64% in Toric-ICL group had postoperative astigmatism ≤0.50 D. No significant changes were observed in postoperative corneal ECD in FS-LASIK group, whereas ECD decreased significantly after the procedure in Toric-ICL group (P=0.0057). The patients undergoing Toric-ICL exhibited no significant changes of postoperative IOP, but the patients receiving FS-LASIK had significantly reduced IOP after the procedure (P<0.001). CONCLUSIONS Although the patients included in Toric-ICL group had higher myopia and astigmatism, Toric-ICL still showed better predictability and efficacy for astigmatic correction in Toric-ICL group. Toric-ICL is an effective and safe equivalent of FS-LASIK for correcting moderate myopia but can be more advantageous for correcting high myopia with astigmatism.

Objective:To explore the effects of Yishen Tonglong Granules (YSTLG) on cell proliferation and apoptosis in a nude mouse model of androgen independent prostate cancer subcutaneous transplantation based on non classical Wnt signaling pathway.Methods:The tumor-bearing nude mouse model was established using the human prostate cancer bone metastatic cell line PC-3. After successful modeling, the mice were equally divided into six groups using the random number table method: model group, Western medicine group, Chinese materia medica low-, medium-, and high-dosage groups, and Chinese materia medica-Western medicine combination group. Corresponding drug interventions were administered to each group. Following 28 consecutive days of drug administration, the nude mice were euthanized. Tumor tissues were harvested for pathological observation via HE staining. Cell proliferation was assessed by immunohistochemistry; apoptosis was detected using TUNEL assay; the expressions of non-canonical Wnt signaling pathway-related proteins (Wnt5a, Rac1, RhoA, NFATc1) were analyzed through Western blot and immunohistochemical methods.Results:THE staining results demonstrated that YSTLG could effectively ameliorate pathological alterations in tumor tissues. Compared with the model group, the Chinese materia medica low-, medium-, and high-dosage groups, as well as the Chinese materia medica-Western medicine combination group, exhibited reduced proliferation indices ( P<0.01), elevated apoptosis indices ( P<0.01), down-regulated protein expressions of Wnt5a, Rac1, RhoA, and NFATc1 ( P<0.01), and decreased optical density values of Wnt5a, Rac1, RhoA, and NFATc1 ( P<0.01). These effects displayed a dosage-dependent trend. The Chinese materia medica-Western medicine combination group achieved the most pronounced therapeutic outcomes. Conclusions:YSTLG may exert inhibitory effects on the proliferation of androgen-independent prostate cancer cells and promote apoptosis, possibly through suppression of the non-canonical Wnt signaling pathway. Furthermore, its combination with Wnt signaling inhibitors may exhibit synergistic therapeutic effects.

Objective:To investigate the effect of gracilis flap in repair of radiation-induced vesicovaginal fistula.Methods:The data of 18 patients with radiation-induced vesicovaginal fistula treated in the Sixth People’s Hospital Affiliated to Shanghai Jiaotong University School of Medicine from March 2021 to August 2022 were retrospectively reviewed. Their age was (57.3±10.4) years. All patients underwent radical surgery for cervical cancer, and received (24.6±2.8)(range from 20 to 30)times of radiotherapy after surger. The median time between the end of radiotherapy and the onset of vesicovaginal fistula was 14.0(7.8, 18.2)months. The median duration of fistula urine was 12.0(9.8, 18.0)months. All patients were required to use median 19.5(15.8, 27.5) pads per day before surgery. The life quality score(QOL)of 18 cases was median 5.0(5.0, 6.0) points. Three cases had performed laparoscopic vesicovaginal fistula repair, two cases had underwent transvaginal vesicovaginal fistula repair, one case had underwent transvaginal and laparoscopic vesicovaginal fistula repair successively, and the remaining 12 cases were new vesicovaginal fistulas. Two cases were combined with rectovaginal fistulas. All patients underwent the repair of vesicovaginal fistula with gracilis flap interposition in prone and folded knife position, by transvaginal route, the vesicovaginal fistula was mobilized and the two layers were closed, and the vascular pedicle gracilis flap of left inner leg was romoved under the skin tunnel to repair the vesicovaginal fistula. Meanwhile, two cases combined rectovaginal fistulas were repaired and closed the rectovaginal fistulas. The urinary catheters were removed at 3 weeks after the operation and urination was recorded.Results:All patients underwent smooth surgery in (96.6±13.2) minutes. The median follow-up was 13.0(9.8, 20.2)(range from 6 to 24)months. The median number of urine pads used per day in 18 patients was 2.0(1.0, 11.8), and significantly reduced ( P<0.01).QOL score was median 1.0(0, 4.2) point and significantly reduced ( P<0.01).Successful outcome was achieved in 12 patients with no leakage of urine in the vagina. Two cases developed urinary incontinence and required conservative treatment, but the curative effect was poor. Two cases still had vaginal urine leakage performed vesicovaginal fistula repair again. One case was successfully repaired without significant urine leakage.The other case still had significant urine leakage and the QOL score was 3 points. She refused further treatment for self-satisfied. Two cases still had vesicovaginal fistula and rectovaginal fistula after the surgery, and refused further surgery. Conclusions:Repair with gracilis flap interposition is a surgical method with few complications and reliable surgical effect for patients with radiation-induced vesicovaginal fistula.

Objective To explore EEG characteristics and the therapeutic effect in children with electrical status epilepticus during slow sleep(ESES).Methods The eligible ESES cases in our center from 2014 to 2020 were included.The age at diagnosis of ESES,the duration of ESES,spike wave index(SWI)during wakefulness and the distribution of spike wave during the period of ESES,age at seizure onset,the clinical syndromes and the outcomes after treatment were analyzed.The ESES cases were divided into 4 groups according to the distribution of spike wave:focal ESES,unilateral ESES,bilateral asymmetric ESES,multiple foci ESES.The SWI during the awake stage were divided into 3 groups based on the different rates:≤20%,21%～49%,≥50%.The therapeutic outcomes were classified into three groups:satisfactory response,seizure control and ineffective.Results 50 cases were included,with 32 males and 18 females.The average onset age of ESES was 6 years and 7 months,and the average duration of ESES was 28 months.A significant correlation between the distribution of ESES and the thera-peutic effects was found,bilateral asymmetric ESES had a good therapeutic effects,while multiple foci ESES showed a poor therapeutic effects.The duration of ESES was significantly correlated with therapeutic effects,and the efficacy was worse when the duration was longer than 1 year.A significant relationship between the SWI during wakefulness of ESES and the therapeutic effects was detected,the patient with SWI≤20%during wakefulness had a good therapeutic effect.There was a negative correlation between the onset age of ESES and the duration of ESES and SWI index during wakefulness.There was a positive correlation between the duration of ESES and SWI index during wakefulness.Conclusion Our results suggest that onset age,distribution,duration and SWI during wake-fulness of ESES were correlated with therapeutic outcomes,The patient with SWI≤20%during wakefulness had a good therapeutic effect and have unfavorable outcomes with ESES last more than 1 year.The earlier onset of ESES,the longer duration of ESES and higher SWI during wakefulness will be showed..

OBJECTIVE: To explore the effectiveness of Nice knot technique for wound closure in Gustilo type ⅢA and ⅢB open tibial fractures. METHODS: A retrospective study was performed on 22 patients with Gustilo type ⅢA and ⅢB open tibial fractures, who underwent wound closure using the Nice knot technique and were admitted between June 2021 and June 2022. There were 15 males and 7 females. The age ranged from 18 to 67 years, with an average of 41.9 years. The causes of injury included traffic accident in 11 cases, falling from height in 7 cases, and heavy object injuries in 4 cases. Fractures were located on the left side in 9 cases and on the right side in 13 cases. And 9 cases were type ⅢA fractures and 13 were type ⅢB fractures according to Gustilo classification. All patients had extensive soft tissue injuries, and no vascular or neurological damage was observed. The time from injury to debridement was 3-8 hours (mean, 6.5 hours). The sizes of wounds before operation and at 2 weeks after operation were measured and wound healing rate at 2 weeks after operation were calculated. The wound healing time and wound healing grading were recorded. The Vancouver Scar Scale (VSS) score was used to assess the wound scar after wound healed and the excellent and good rate was calculated. RESULTS: The wound area was 21.0-180.0 cm ² (mean, 57.82 cm ²) before operation, and it was 1.2-27.0 cm ² (mean, 6.57 cm ²) at 2 weeks after operation. The wound healing rate at 2 weeks after operation was 76%-98% (mean, 88.6%). After operation, 2 cases needed to adjust Nice knot due to skin cutting and 1 case occurred soft tissue infection on the wound. The other patient's wounds healed. The average wound healing time was 27.8 days (range, 18-44 days). And the wound healing were grade A in 13 cases and grade B in 9 cases. VSS score was 2-9, with an average of 4.1; 10 cases were rated as excellent, 10 as good, and 2 as poor, with an excellent and good rate of 90.9%. All patients were followed up 9-24 months (mean, 14.6 months). During follow-up, no deep infection or osteomyelitis occurred. Two cases experienced fracture non-union, and were treated with compression fixation and bone grafting. The fractures of the other patients all healed, with a healing time of 85-190 days (mean, 148.2 days). CONCLUSION Nice knot technique can be used in wound closure of Gustilo type ⅢA and ⅢB open tibial fractures effectively, which is easy to operate.

Objective:To explore the correlation between clinical phenotypes and genotypes among 46 children with SCN1A-related developmental epileptic encephalopathy (DEE). Methods:Clinical data of 46 children with DEE and SCN1A variants identified at the Guangzhou Women and Children′s Medical Center between January 2018 and June 2022 were collected. The children were grouped based on their age of onset, clinical manifestations, neurodevelopmental status, and results of genetic testing. The correlation between SCN1A genotypes and clinical phenotypes was analyzed. Results:Among the 46 patients, 2 children (4.35%) had developed the symptoms before 3 months of age, 42 (91.30%) were between 3 to 9 months, and 2 cases (4.35%) were after 10 months. Two cases (4.35%) presented with epilepsy of infancy with migrating focal seizures (EIMFS), while 44 (95.7%) had presented with Dravet syndrome (DS), including 28 cases (63.6%) with focal onset (DS-F), 13 cases (29.5%) with myoclonic type (DS-M), 1 case (2.27%) with generalized type (DS-G), and 2 cases (4.55%) with status epilepticus type (DS-SE). Both of the two EIMFS children had severe developmental delay, and among the DS patients, 7 cases had normal development, while the remaining had developmental delay. A total of 44 variants were identified through genetic sequencing, which included 16 missense variants and 28 truncating variants. All EIMFS children had carried the c. 677C>T (p.Thr226Met) missense variant. In the DS group, there was a significant difference in the age of onset between the missense variants group and the truncating variants group ( P < 0.05). Missense variants were more common in D1 (7/15, 46.7%) and pore regions (8/15, 53.3%), while truncating variants were more common in D1 (12/28, 42.9%). Children with variants outside the pore region were more likely to develop myoclonic seizures. Conclusion:The clinical phenotypes of DEE are diverse. There is a difference in the age of onset between individuals with truncating and missense variants in the SCN1A gene. Missense variants outside the pore region are associated with a higher incidence of myoclonic seizures.

Hepatitis E is a globally distributed infection that varies in seroprevalence between developed and developing regions.In the less developed regions of Asia and Africa,a high seropositivity rate has been reported for hepatitis E virus(HEV)antibodies.Although acute hepatitis E is often self-limited and has a favorable prognosis,some populations experience severe manifestations,which may progress to liver failure.Moreover,some immunocompromised patients are at risk of developing chronic HEV infection and cirrhosis.Proactive screening,reducing misdiagnosis,improving patient management,timely anti-viral therapy for severe and chronic cases,and vaccination of high-risk groups are important measures to reduce the morbidity of hepatitis E.This review focused on the clinical presentation,management,and prevention of hepatitis E.

Background and aim:Few studies have reported hepatitis B surface antigen(HBsAg)kinetics after nucleos(t)ide analog(NA)discontinuation in patients with noncirrhotic chronic hepatitis B(CHB).The study specifically investigated long-term HBsAg kinetics after NA discontinuation. Methods:Between January 2014 to January 2024,this study prospectively enrolled 106 outpatients with noncirrhotic CHB who met the discontinuation criteria after NA consolidation treatment.Demographic,clinical,and laboratory data were collected and analyzed after NA discontinuation. Results:Ninety-six patients who finished 5 years of follow-up were included.HBsAg remained unde-tectable in 29 patients with end of treatment(EOT)HBsAg negativity.Among 67 patients with EOT HBsAg positivity,HBsAg seroclearance occurred in 12(17.9％)patients with an estimated annual inci-dence of HBsAg seroclearance of 3.6％.Patients with EOT HBsAg levels of ≤1000 IU/mL had a higher HBsAg seroclearance rate than those with EOT HBsAg levels of＞1000 IU/mL(33.3％vs.5.4％).The pro-portion of patients with HBsAg ≤1000 IU/mL increased during follow-up.Logistic regression analysis indicated that the EOT HBsAg level was an independent factor for HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL.The optimal EOT HBsAg cutoff for both HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL was 359 IU/mL. Conclusions:Patients with EOT HBsAg negativity experienced no relapse and maintained HBsAg sero-clearance during 5 years of follow-up after NA discontinuation.A higher HBsAg seroclearance rate can be obtained in patients with EOT HBsAg levels of ≤1000 IU/mL during 5 years of follow-up after NA discontinuation.Close monitoring and proper NA retreatment are recommended to guarantee the safety of NA discontinuation.

Objective:To investigate the surgical treatment effect and prognostic factors of hilar cholangiocarcinoma.Methods:This is an ambispective cohort study. From August 2005 to December 2022,data of 510 patients who diagnosed with hilar cholangiocarcinoma and underwent surgical resection at the Hepatobiliary Center of the First Affiliated Hospital of Nanjing Medical University were retrospectively collected. In the cohort,there were 324 males and 186 females,with an age of ( M (IQR)) 63(13)years (range:25 to 85 years). The liver function at admission was Child-Pugh A (343 cases,67.3%) and Child-Pugh B (167 cases,32.7%). Three hundred and seventy-two(72.9%) patients had jaundice symptoms and the median total bilirubin was 126.3(197.6) μmol/L(range: 5.4 to 722.8 μmol/L) at admission. Two hundred and fourty-seven cases (48.4%) were treated with percutaneous transhepatic cholangial drainage or endoscopic nasobiliary drainage before operation. The median bilirubin level in the drainage group decreased from 186.4 μmol/L to 85.5 μmol/L before operation. Multivariate Logistic regression was used to identify the influencing factors for R0 resection,and Cox regression was used to construct multivariate prediction models for overall survival(OS) and disease-free survival(DFS). Results:Among 510 patients who underwent surgical resection,Bismuth-Corlett type Ⅲ-Ⅳ patients accounted for 71.8%,among which 86.1% (315/366) underwent hemi-hepatectomy,while 81.9% (118/144) underwent extrahepatic biliary duct resection alone in Bismuch-Corlett type Ⅰ-Ⅱ patients. The median OS time was 22.8 months, and the OS rates at 1-,3-,5-and 10-year were 72.2%,35.6%,24.8% and 11.0%,respectively. The median DFS time was 15.2 months,and the DFS rates was 66.0%,32.4%,20.9% and 11.0%,respectively. The R0 resection rate was 64.5% (329/510), and the OS rates of patients with R0 resection at 1-,3-,5-and 10-year were 82.5%, 48.6%, 34.4%, 15.2%,respectively. The morbidity of Clavien-Dindo grade Ⅲ-Ⅴ complications was 26.1%(133/510) and the 30-day mortality was 4.3% (22/510). Multivariate Logistic regression indicated that Bismuth-Corlett type Ⅰ-Ⅲ ( P=0.009), hemi-hepatectomy and extended resection ( P=0.001),T1 and T2 patients without vascular invasion (T2 vs. T1: OR=1.43 (0.61-3.35), P=0.413;T3 vs. T1: OR=2.57 (1.03-6.41), P=0.010;T4 vs. T1, OR=3.77 (1.37-10.38), P<0.01) were more likely to obtain R0 resection. Preoperative bilirubin,Child-Pugh grade,tumor size,surgical margin,T stage,N stage,nerve infiltration and Edmondson grade were independent prognostic factors for OS and DFS of hilar cholangiocarcinoma patients without distant metastasis. Conclusions:Radical surgical resection is necessary to prolong the long-term survival of hilar cholangiocarcinoma patients. Hemi-hepatectomy and extended resection,regional lymph node dissection and combined vascular resection if necessary,can improve R0 resection rate.
