Hydroxyethyl chitin (HECH) is a water soluble chitin derivative made by etherification of chitin, ethylene chlorohydrin was used as etherification reagent in this reaction. A novel interpenetrating polymer network (IPN) composed of HECH/PAA was prepared. The IR spectra confirmed that HECH/PAA was formed through chemical bond interaction. The sensitivity of this hydrogel to temperature and pH was studied. The swelling ratio of this hydrogel in artificial intestinal juice is much greater than that in artificial gastric juice. The IPN hydrogel exhibited a typical pH-sensitivity, and its degree of swelling ratio increased with the increase of temperature. The sustained-release drug system of Dichlofenac potassium was prepared by using HECH/PAA as the drug carrier. The release experiment showed a perfect release behavior in artificial intestinal juice. This IPN is expected to be used as a good drug delivery system of enteric medicine.

Objective To explore the risk factors of inguinal metastasis in squamous cell carcinoma of the penis, screening lymph node metastasis high-risk patients. Methods The clinical and pathological data of 81 consecutive patients with squamous cell carcinoma of the penis were analyzed retrospectively. Age at presentation ranged from 27 to 81 years with a median of 49 years. Course of disease within one year of patients with 46 cases (56.8%), 1 year above 35 eases (43.2 %). Seventyfive patients underwent bilateral inguinal lymph node dissection, and 6 patients had unilateral inguinal lymph node dissection. Clinical stage of the primary tumor was assigned according to the 2002 TNM staging system. Variables included patients' age, redundant prepuce and/or phimosis, tumor site,size, number, macroscopic growth pattern, histological grade, inguinal physical examination and the size of inguinal lymph nodes. Results Of the 81 patients, 42 (51.9%) were staged as pN+ and 39 (48. 1%) as pN0. Metastases occurred in 32.0% (16/50) of G1, 78.3% (18/23) of G2 and 100. 0%(8/8) of G3 cases, with significant differences among them (P= 0. 015). According to the inguinal lymph node physical examination results, 63 were staged as clinically node-positive (cN+) and 18 as clinically node-negative (cN0). Metastases occurred in 63. 5% (40/63) of cases of cN+, as compared with 11.1% (2/18) of cases of cN0(P=0. 012). At a median follow up of 40 months (ranged 2-127 months), the 5-year disease free survival rates for positive and negative inguinal lymph nodes metastasis were 71.4% and 92.3%, respectively (P=0. 005) , and the 5-year cancer specific survival rates were 79.0% and 91.4%, respectively (P=0.001). Conclusions Inguinal physical examination and histological grade were the strongest predictors of inguinal metastasis. The patients with inguinal lymph nodes metastasis have lower 5-year disease free survival rates and cancer specific survival rates,and should receive positive treatment measures.

Objective:To explore the clinical effect of Beling Weitong granule combined with proton pump inhibitors in senile gastroesophageal reflux disease(GERD).Methods:A total of 186 patients with GERD treated in the Second People′s Hospital of Dujiangyan from January 2020 to December 2021 were retrospectively selected as the study subjects, of which 93 patients received proton pump inhibitor (prilosec) orally (control group) and 93 patients received Beling Weitong granule combined with prilosec orally (combination group). Both groups were treated for 8 weeks. Symptom score, reflux symptom-based questionnaire (GERDQ) score, clinical efficacy, serum levels of gastrin-17 (G-17), motilin (MTL), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) before and after treatment and safety were compared between the two groups.Results:After treatment, the symptom score and GERDQ score in the combination group were lower than those in the control group: (8.28 ± 2.57) scores vs. (15.68 ± 3.69) scores, (8.15 ± 2.23) scores vs. (10.50 ± 2.45) scores, there were statistical differences ( P<0.05). The total effective rate in the combination group was higher than that in the control group: 96.77% (90/93) vs. 87.10% (81/93), there was statistical difference ( χ2 = 5.87, P<0.05). After treatment, the levels of serum G-17 and MTL in the combination group were higher than those in the control group, the levels of IL-6 and TNF-α were lower than those in the control group: (7.48 ± 0.96) pmol/L vs. (6.55 ± 0.83) pmol/L, (206.96 ± 37.83) pg/L vs. (184.75 ± 35.69) pg/L, (9.38 ± 1.92) ng/L vs. (14.13 ± 2.04) ng/L, (9.41 ± 1.85) ng/L vs. (12.01 ± 2.11) ng/L, there were statistical differences ( P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P>0.05). Conclusions:Beling Weitong granule combined with proton pump inhibitor in the treatment of senile gastroesophageal reflux disease is effective, and it is safe.

OBJECTIVETo define the clinicopathological risk factors of intravesical recurrence of primary transitional cell carcinoma of the ureter after surgical intervention.

METHODSPatients with primary carcinoma of the ureter treated between January 2000 and December 2010 were retrospectively analyzed. The intravesical recurrence-free survival rate was calculated using Kaplan-Meier method. Multivariate analysis was conducted with Cox's regression.

RESULTSA total of 104 patients were enrolled, who were followed up for a median of 46 months (13-89 months). Thirty-nine of the patients showed postoperative intravesical recurrence. Urine exfoliative cytology (P=0.000), number of tumors (P=0.006), tumor grade (P=0.039) and co-existence of bladder tumor (P=0.014) were found to independently influence the postoperative intravesical recurrence. Patients with more risk factors had poorer intravesical recurrence-free survival.

CONCLUSIONUrine exfoliative cytology, number of tumors, tumor grade and co-existence of bladder tumor are independent risk factors for postoperative intravesical recurrence of primary transitional cell carcinoma of the ureter. Close follow-up and rigorous treatment are essential for patients with high risk factors.

OBJEVTIVETo investigate the expression of cysteine-rich secretory protein 2 (CRISP2) in spermatozoa of patients with asthenozoospermia and explore its clinical significance.

METHOSSemen samples were collected from 24 normal volunteers and 24 patients with asthenozoospermia for detecting CRISP2 mRNA and protein expressions using qRT-PCR and Western blotting, respectively. The correlation of CRISP2 expressions with sperm morphology, progressive motility and fertility prognosis were analyzed in patients with asthenozoospermia.

RESULTSCRISP2 protein expression was obviously lowered in the ejaculated spermatozoa of patients with asthenozoospermia as compared to the normal volunteers, but no significant difference in CRISP2 mRNA expression was found between the two groups. Correlation analysis showed that CRISP2 protein expression was positively correlated with normal sperm morphology (r=0.6182, P=0.0037) and progressive motility (r=0.6309, P=0.0029). Follow-up study of the patients revealed a higher fertility rate in patients with a relatively high CRISP2 protein expression than in those with low CRISP2 protein expression (80.0% vs 20.0%, P=0.0230).

CONCLUSIONThe expression level of CRISP2 protein is positively correlated with normal sperm morphology and progressive motility. A reduced CRISP2 protein expression indicates poor fertility prognosis of patients with asthenozoospermia, suggesting the potential value of CRISP2 as a novel therapeutic target for treating asthenozoospermia.

Objective:To compare the impact of different portal exposure techniques in the Kasai surgery on children with type Ⅲ. biliary atresia during their different perioperative periods.Methods:A retrospective study was performed on the data of children with type Ⅲ. biliary atresia who underwent Kasai surgery at Fujian Children's Hospital from January 2017 to October 2020. Of 45 children enrolled in this study, there were 24 males and 21 females, aged (71.3±21.0) days. Patients who had left and right branches of the portal vein and the left and right hepatic arteries in the portal area being completely freed and elastically stretched during the Kasai operation were included into the free group ( n=22) and the remaining patients were included in the control group ( n=23). Postoperative hospital stay, postoperative direct bilirubin levels, postoperative complications and transplant-free survival after the Kasai operation were compared between the 2 groups. Results:Postoperative hospital stay of (17.1±4.4) d in the free group was significantly lower than that in the control group (20.1±5.4) d, ( t=2.07, P=0.044). The direct bilirubin level at 3 months after surgery for the control group was 30.0 (109, 108.0)μmol/L, which was significantly higher than that of 14.5 (4.0, 37.5) μmol/L in the free group ( Z=-2.16, P=0.031). Twenty-one patients (91.3%) in the control group had frequent attacks of postoperative cholangitis, compared with 13 patients (59.1%) in the free group. The difference was statistically significant (χ 2=4.69, P=0.030). Eleven surviving patients (47.8%) in the control group did not undergo liver transplantation at one year after surgery, compared with 15 patients (68.2%) in the free group. At two years after surgery, 7 surviving patients (30.4%) in the control group did not undergo liver transplantation compared with 10 patients (45.5%) in the free group. Conclusion:For children with type Ⅲ. biliary atresia, completely freeing the left and right branches of portal vein, and left and right hepatic arteries in the liver portal area, and elastically stretching these vessels to expose the portal area of the liver during Kasai surgery increased surgical safety and reduced hospital stay.
