Objective To explore the clinical effect of transrectal ultrasound-guided puncture and cathetering drainage in the treatment of high-position perianal abscess. Methods Eighty patients with high-position perianal abscess, who admitted to Shuguang Hospital of Shanghai University of Traditional Chinese Medicine from Jan. of 2015 to 2018, were randomized into interventional therapy group and surgical treatment group, with 40 cases in each group. The patients in the interventional therapy group were treated with cathetering drainage guided by transrectal ultrasound, and the patients in the surgical treatment group were treated with traditional incision drainage. The clinical effect was evaluated in the two groups, and the pain, fever and exudation scores, white blood cell count, C-reactive protein level, maximal section area of abscess cavity, and wound healing time were compared between the two groups before operation and on 3 days and 7 days after operation. Results The total effective rates of the interventional therapy and surgical treatment groups were 87.5% (35/40) and 80% (32/40), respectively, and the difference was significant (χ2=1.385, P=0.709). On 3 days and 7 days after operation, the pain score, exudation score, white blood cell count, C-reactive protein level and maximum section area of the abscess cavity were significantly lower in the interventional therapy group than those in the the surgical treatment group (all P<0.01). The patients with retrorectal abscess or high intersphincteric abscess in the interventional therapy group had shorter wound healing time versus the patients in the surgical treatment group (both P<0.01). Conclusion Compared with traditional incision drainage, cathetering drainage guided by transrectal ultrasound can reduce pain and decrease exudation of the patients with high-position perianal abscess to effectively control infection.

Objective To investigate the effect of IFN-γ on the proliferation and migration of esophageal squamous cell carcinoma cell line Eca9706 and related mechanism. Methods Cells were cultured in vitro and treated with interferon-γ. Cell morphology changes were observed under microscope, cell proliferation ability was detected by CCK-8 experiment, and cell migration ability was detected by cell scratch experiment and Transwell experiment. Real-time PCR method was used to detect the expression efficiency of chemokine CXCL8 (interleukin 8), and the ELISA experiment was used to detect the change of CXCL8 secretion. Results Compared with the blank control group, Eca9706 cells treated with different concentrations of interferon-γ did not change significantly in cell morphology. CCK8 experiment confirmed that the proliferation ability of Eca9706 cells after IFN-γ treatment was significantly reduced (P < 0.01). Cell scratch experiment found that IFN-γ significantly decreased the migration ability of Eca9706 cells (P < 0.01). Transwell experiment showed that after IFN-γ treatment, the migration ability of Eca9706 cells was significantly inhibited (P < 0.01). CXCL8 gene expression level in Eca9706 cells treated with interferon-γ was significantly down-regulated (P < 0.01), and the amount of CXCL8 secretion significantly reduced (P < 0.05). Conclusion Interferon-γ can inhibit the proliferation and migration of esophageal cancer cell line Eca9706, which may be related to its inhibition of the expression and secretion of CXCL8.

ObjectiveTo investigate the effect of arsenic trioxide-loaded CalliSpheres beads (CBATO) in transarterial chemoembolization (TACE) in the treatment of rabbits with VX2 liver tumor. MethodsA total of 120 tumor-bearing rabbits were divided into control group, CalliSpheres beads (CB) group (blank beads for TACE), CBATO group, and conventional TACE (cTACE) group (arsenic trioxide lipiodol for TACE) using a random number table, with 30 rabbits in each group. Five rabbits in each group were sacrificed at 12 hours and on days 3, 7, and 14 after TACE, and immunohistochemistry was used to measure the proliferation index and apoptosis percentage of tumor cells in the residual tumor area. The tumor necrotic volume was measure on day 7 after TACE, and the growth rate and necrosis rate of tumor cells were calculated. Ten rabbits were randomly selected from each group for the observation of survival time. An analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kaplan-Meier survival analysis was used to evaluate survival time, and the log-rank test was used for comparison. ResultsOn day 7 after TACE, the CBATO group had a significantly lower growth rate and a significantly higher necrosis rate of tumor cells than the cTACE group, the CB group, and the control group (all P＜0.05). At each time point after TACE, there were significant differences in the proliferation index and apoptosis percentage of tumor cells between the CBATO group and the other three groups (all P＜0.05). The median survival time was 26 days in the CBATO group, 18.5 days in the CB group, 22 days in the cTACE group, and 15.5 days in the control group, and the CBATO group had a significantly longer survival time than the other three groups (χ2=3.95, 8.99, and 13.47, P=0.049, P=0.003, and P＜0.01). ConclusionCBATO has a better effect than cTACE and CB in the treatment of rabbits with VX2 liver tumor and can significantly improve tumor necrosis rate, promote the apoptosis of tumor cells, and prolong the survival time of experimental animals.

OBJECTIVETo introduce the advantages of the circumcision with a scalpel by inserting a piece of gauze between the inner prepuce and superficial fascia.

METHODSFrom November 2000 to March 2006, 2 100 patients with redundant prepuce, aged 6-78 years, averaging 23, were circumcised with a scalpel by inserting a piece of gauze between the inner prepuce and superficial fascia. Of all the cases, 1 799 (85.7%) were classified as Type I, 237 (11.3%) as Type II and 64 (3.0%) as Type III redundant prepuce. The mean operation time was 20 minutes (15-35 min).

RESULTSThe incisions were all healed in one stage, with good appearance, no infection and no disruption. Bleeding occurred in 12 cases 648 hours after the operation and delayed bleeding in 3 cases.

CONCLUSIONThe circumcision with a scalpel by inserting a piece of gauze between the inner prepuce and superficial fascia, with easier performance, fewer complications and less bleeding, and capable of preserving more and continuous superficial fascia and giving a better appearance, well deserves to be popularized in clinical practice.

OBJECTIVETo observe the effect of traditional Chinese medicine formulas clearing away heat and promoting blood circulation-Biejiayinzi (BJYZ), Gexiazhuyu Tang (GXZYT) and Fugan Wan (FGW) on liver fibrosis in CCl4 mice by screening and analyzing formula-syndrome database of kidney and liver fibrosis based on the principle of formula-syndrome, compared with pivot-harmonizing decoction.

METHODTen-week-old male C57BL/6 mice, with the weight of (20 +/- 3) g, were randomly divided into 6 groups: the normal group, the model group, the BJYZ group, the GXZY group, the FGW group and the XST group. Except the normal group, other groups were abdominally injected with 10% CCl4 olive oil solution a dose of 2 mL x kg(-1) body weight for four weeks, three times each week. Meanwhile, the latter four groups were administered with extracts of BJYZ, GXZYT, FGW and XST, respectively, once every day, concomitantly continued CCl4 administration. The normal and the model groups were given the same volume of deionized water. The levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (gamma-GT), Alb and TBil were detected by chemiluminescence. The hydroxyproline (HYP) content was detected by acid hydrolysis method. The hepatic collagen deposition was evaluated with Sirius red staining.

RESULTCompared with the normal group, the model group recorded notable decrease in weight and increase in the ratio of liver weight and body weight and the ratio of spleen weight and body weight, with obvious fatty degeneration and inflammatory necrosis in liver cells. Collagen fiber deposition was so notable to form fibrous septums and pseudolobules. The levels of serum ALT, AST, TBil, gamma-GT, the HYP content in liver tissue and the deposition of hepatic collagen were significantly increased in the model group. Compared with model group, Serum AST were significantly decreased in BJYZ group as gamma-GT decreased in the GXZYT group, without notable decrease in degeneration and inflammatory necrosis in liver cells and collagen deposition. The GXZYT group showed significant decrease in gamma-GT, with slight improvement in degeneration and inflammatory necrosis in liver cells and reduction in collagen deposition. The ratio of liver weight and body weight, AST, gamma-GT and HYP content were significantly decreased in the FGW group, with slight improvement in degeneration and inflammatory necrosis in liver cells and reduction in collagen deposition. The XST group showed decrease in the ratio of liver weight and body weight, with no obvious change in inflammation and fibrosis of hepatic tissue.

CONCLUSIONFGW shows the best effect of prevention and treatment of liver fibrosis in CCl4 mice.

Objective:To investigate the morphological feature and clinical significance of MRI around tumor after drug-eluting bead transcatheter arterial chemoembolization (DEB-TACE) of primary hepatocellular carcinoma.Methods:We reviewed and analyzed the data of hepatocellular carcinoma patients admitted from January 2017 to December 2018 in the Department of Radiological Intervention of the First Affiliated Hospital of Zhengzhou University. A total of 42 patients were enrolled, including 35 males and 7 females, aged (57.0±11.9) years. For the first time after operation, MRI enhancement showed peri-tumor margin enhancement as the starting point of follow-up. Follow-up and measure enhanced edge thickness, delayed enhancement, progression or remission data.Results:A total of 49 tumors and 84 peritumoral enhancement margins were included in 42 patients, with 30 sharp type , 40 rough type and 14 nodular type. The thickness of sharp type is less than that of rough type and nsodular type, and the differences were statistically significant (all P<0.05). The sharp type is the majority of the tumors with maximum diameter <5 cm, rough type and nodule type are the majority of tumors with maximum diameter ≥5 cm. Most of the sharp type are continuously enhanced, while the rough type and nodular type are not. Most sharp type relief (93.3%, 28/30), while rough type (80.0%, 32/40) and nodular type ( n=12) are mostly of deterioration, the differences are statistically significant (all P<0.05). Conclusion:Compared with the rough type and nodular type, the sharp type usually occurs in smaller tumors and more prone to local mitigation in the enhanced morphology around MRI after DEB-TACE in primary hepatocellular carcinoma.

Objective:To analyze the efficacy and safety of nalbuphine for analgesia in patients with non-mechanical ventilation in intensive care unit (ICU).Methods:From December 2018 to August 2021, a multicenter randomized controlled clinical study was conducted to select non-mechanical ventilation patients with analgesic needs admitted to ICU of four hospitals in Henan Province and Guizhou Province. Patients were randomly assigned to nalbuphine group and fentanyl group. The nalbuphine group was given continuous infusion of nalbuphine [0.05~0.20 mg/(kg·h)], and the fentanyl group was given continuous infusion of fentanyl [0.5~2.0 μg/(kg·h)]. The analgesic target was critical-care pain observation tool (CPOT) score<2. The observation time was 48 hours. The primary endpoint was CPOT score, the secondary endpoints were Richmond agitation-sedation score (RASS), ICU length of stay, adverse events, and proportion of mechanical ventilation. The quantitative data of the two groups were compared by t test or Mann-Whitney U test. The enumeration data were compared by chi square test or Fisher exact probability method. The data at different time points between groups were compared by repeated measures analysis of variance. Results:A total of 210 patients were enrolled, including 105 patients in the nalbuphine group and 105 patients in the fentanyl group. There was no significant difference in baseline data between the two groups (all P>0.05). There was no significant difference in CPOT score between nalbuphine group and fentanyl group at each time point after medication ( P>0.05), the CPOT score of both groups at each time point after medication was significantly lower than that before medication, and the analgesic target could be achieved and maintained 2 hours after medication. There was no significant difference in RASS between the two groups at each time point after medication ( P>0.05), which was significantly lower than that before medication, and the target sedative effect was achieved 2 hours after medication. There was no significant difference in ICU length of stay between nalbuphine group and fentanyl group [5.0(4.0,7.5) d vs. 5.0(4.0,8.0) d, P=0.504]. The incidence of delirium, nausea and vomiting, abdominal distension, pruritus, vertigo and other adverse events in the nalbuphine group was lower than that in the fentanyl group (all P<0.05). There was no significant difference in the incidence of other adverse events such as deep sedation, hypotension and bradycardia between the two groups (all P>0.05). The incidence of respiratory depression in nalbuphine group was not significantly different from that in fentanyl group ( P>0.05), but the proportion of mechanical ventilation was significantly lower than that in the fentanyl group [1.9% (2/105) vs. 8.6%(9/105), P=0.030]. Conclusions:Nalbuphine could be used for analgesia in ICU patients with non-mechanical ventilation. The target analgesic effect could be achieved within 2 hours, and it had a certain sedative effect with a low incidence of adverse reactions.

Objective:To investigate the feasibility of "twelve-section ultrasonic screening diagnosis method" in screening for neonatal complex congenital heart disease (CHD) in primary hospitals.Methods:This is a prospective study. A total of 71 580 newborns were screened for CHD using the "twelve-section ultrasonic screening diagnosis method" from four pilot units in Hebei province, which were Bo'ai Hospital of Huanghua Development Zone, Traditional Chinese Medicine Hospital of Fengning County, Maternity & Child Healthcare Hospital of Tang Country, and Maternity & Child Healthcare Hospital of Rongcheng Country, from November 2015 to December 2019. Another 262 children with CHD were enrolled, including 39 with complex CHD. These cases received ultrasonography at four pilot units above and then were transferred to CHD Screening Diagnosis and Treatment Center of Hebei Children's Hospital (our center) prior to the implementation of "twelve-section ultrasonic screening diagnosis method" from June 2012 to June 2014, who were all confirmed by surgery. Set the diagnosis results of our center as the gold standard, the sensitivity, specificity, and diagnostic consistency rate in screening for complex CHD cases were calculated. Receiver operating characteristic (ROC) analysis and Chi-square test were used to compare and analyze the sensitivity for screening neonatal complex CHD before and after implementing the method. The screening results of complex CHD after implementing the method between the pilot units and our center as well as between the four pilot units were compared and analyzed using Chi-square test. Results:A total of 553 (0.77%) CHD cases were detected by the "twelve-section ultrasound screening diagnosis method", including 66 cases of complex CHD and 487 cases simple CHD. Among the cases screened using the method, there were three false negative cases (one case with total anomalous pulmonary venous drainage, one with abnormal coronary artery originating from pulmonary artery, and one with atresia of distal to the left subclavian artery, aortic arch and left aortic arch of double-arch), one false positive case (false echo loss of aortopulmonary septal that was misdiagnosed as aortopulmonary septal defect), five cases of misdiagnosis (one common pulmonary venous atresia case that was misdiagnosed as total anomalous pulmonary venous drainage, one persistent stenosis of the fifth aortic arch that was misdiagnosed as coarctation of aorta, one pulmonary artery sling that was misdiagnosed as absence of left pulmonary artery, one severe coarctation of aorta that was misdiagnosed as interruption of aortic arch, and one aortic isthmus atresia that was misdiagnosed as coarctation of aorta), and all were complex CHD cases. A total of 68 cases (12.3%) of complex CHD were confirmed by our center. The overall sensitivity, specificity, and diagnostic consistency rate of screening were 95.6% (65/68), 99.8% (484/485), and 86.8% (59/68), respectively and the area under ROC curve was 0.98. Before the implementation, the overall sensitivity, specificity, and diagnostic coincidence rates of ultrasonic screening for complex CHD were 69.2%(27/39), 95.5%(213/223), and 61.5% (24/39), respectively, and the area under ROC curve was 0.82. The sensitivity of complex CHD screening was significantly increased after implementing the method ( χ2=14.28, P<0.05). There was no significant statistical significance in the sensitivity for screening complex CHD after the implementation between the pilots and our center or between the four pilots (all P>0.05). Conclusions:"Twelve-section ultrasonic screening diagnosis method" is suitable for the screening of neonatal complex CHD in hospitals at the county level. However patients with some special types of complex CHD are recommended to be transferred for a more accurate diagnosis.
