Objective To analyzed the clinical features,laboratory examination and sacroiliac joint CT signs of ankylosing spondylitis.Methods Of all 22 cases,20 were male,2 were female,the age ranges from 14 to 70 with average of 27.9.All patients accepted spiral CT axial scan of sacoiliac joint,their prominent clinical features and laboratory examination were registered.Results Hip pain,waist pain and lmitation of stoop were outstanding clinical features,their proportions were 63.3%,40.9%,31.8% respectively.Laboratory exanination:positive rates of HLA-B 27 and RF were respectively 100%,27.2%.Percentages of ESR speeding and CRP increasing were respectively 90.9%,31.8%.Among all CT signs,coarseness,dimness and erosion of SI joint had the highest percentage(68.1%).Others,such as osteosclerosis was in 50%,joint narrowing was in 36.3%,joint union was in 9.1%.Conclusion In patients with ankylosing spondyeitis, hip pain is common clinical feature.Positive HLA-B 27 ,mcreasing of ESR and CRP are valuable for diagnosis.SI joint CT examination often demonstrates joint coraseness,dimness and erosion.

Objective To compare the concordance among RECIST, EASL and modified RECIST criteria for the evaluation of tumor response after transarterial chemoembolization of primary liver cancer.Methods Fifty patients with primary liver cancer underwent 2 TACE cycles separated by 30-40 days.Triphasic helical CT or MRI scans were performed at baseline, at 4 weeks after TACE procedure, and 2 independent radiologists evaluated tumor response according to above-mentioned three different criteria. Chisquare test was used to compare the response rate, and kappa coefficients were used to evaluate the coherence. Results When tumor responses were evaluated using the RECIST-EASL and modified RECIST criteria, the numbers of the patients achieved complete response, partial response, stable disease,progressive disease were 0, 10, 30, 10; 6,21,14,9; 6,21,13,10 respectively. The objective response rates for three different criteria were 20%, 54%, 54% respectively ( P ＜ 0. 01 ). Kappa coefficients between RECIST and EASL, between RECIST and modified RECIST, between EASL and modified RECIST were 0. 382, 0. 170, and 0. 857 (P = 0. 000). Conclusions RECIST criteria underestimates the extent of tumor response after TACE in primary liver cancer. Both EASL and modified RECIST criteria appear to agree with each other in determining treatment response. Furthermore, the modified RECIST is more convenient in clinical practice compared with EASL criteria.

Objective To investigate the influence of psychological intervention on the physical and psychomotor development of children born of assisted reproductive technology. Methods 329 cases of ART born children in our hospital were set as the experimental group,the parturients were given pertinent psychological intervention.254 cases of children of spontaneous pregnancy were selected as the control group.The two groups were given follow-up for 24 months.Their physical condition at birth and psychomotor development during follow - up period were compared. Results Compared with the control group,length of infants at birth,body mass of the experimental group were significantly lower,and the incidence rate of premature birth,low birth weight,NICU stay during neonatal stage were higher.But there were no differences in psychomotor development between two groups. Conclusions ART born children of 24-month old show normal psychomotor development,but there are still more unfavorable physical factors,therefore,pertinent nursing intervention should be given based upon psychological intervention in clinic.

Objective To evaluate the technical feasibility and safety of a single-incision technique via axillary vein (AV) for placement of totally implantable venous access port (TIVAP) guided by ultrasound combined with DSA in clinical application. Methods We retrospectively analyzed clinical data of 240 patients who received TIVAP by single incision technique via AV access guided by ultrasound combined with DSA. We observed and recorded operation-related information such as AV width, AV puncture success rate, implantation success rate, ultrasound-guided puncture time, operation time and intraoperative and postoperative complications, etc. Results All 240 patients were successfully implanted with TIVAP, and the success rate was 100%. In 229 cases, TIVAP was implanted through single-incision AV puncture under the guidance of ultrasound combined with DSA, and the success rate of AV puncture was 95.42% (229/240). In 11 cases, TIVAP was implanted through the ipsilateral internal jugular vein (IJV) under the guidance of ultrasound combined with DSA due to the failure of AV puncture. In the 240 patients, the average width of AV of the intended puncture segment was (7.56±1.26) mm measured by preoperative ultrasound exploration and positioning, in which 195 cases were successfully punctured once, 26 cases were successfully punctured twice, and 8 cases were successfully punctured three times, with the success rate of 81.25%, 10.83% and 3.34%, respectively. The average puncture time under ultrasound guidance was (0.85±0.52) min, and the average operation time was (25.9±4.8) min. The incidence of intraoperative complications was 1.67% (4/240). No hemothorax, hemopneumothorax or serious fatal complications occurred. The incidence of complications during TIVAP retention was 2.92% (7/240). No complication such as catheter-related bloodstream infection, catheter-related venous thrombosis, catheter rupture/displacement, clipping syndrome or drug extravasation was observed. Conclusion Ultrasound combined with DSA guided single-incision technique via AV access in the implantation of TIVAP is a feasible and safe implantation method with high technical success rate, short operation time and low risk of complications. It can be used as another choice of TIVAP implantation method.

Objective To analyze the distribution of various genotypes of human cytomegalovirus glycoprotein N ( HCMV gN) in patients with HIV infection; to investigate the effects of HCMV-HIV co-in-fection on disease progression and the relationships between HCMV gN genotypes and disease progression. Methods Patients with active HCMV infection were screened out from 359 patients with HIV infection by using the pp65 antigenemia assay.The genes encoding HCMV gN ( UL73 ) were amplified by nested PCR ( nPCR) .The amplicons were digested by restriction enzymes including MboⅠ, ScaⅠ and SalⅠ.Then, the restricted fragment length polymorphisms were further analyzed on 4%agarose gel.The relationships be-tween HCMV genotypes and the morbidity and mortality of acquired immune deficiency syndrome ( AIDS ) were investigated via a prospective study.Results Among the 359 patients with HIV infection, 28 subjects were positive for the HCMV pp65 antigenemia assay.The HCMV gN genotypes in 20 patients with active HCMV infection were distributed as: gN-3a (4/20, 20%), gN-1 (4/20, 20%), gN-4d (1/20, 5%), gN-4b (1/20, 5%) and mixed infection (10/20, 50%).Patients with HCMV-HIV co-infection were more likely to develop AIDS during the follow-up period (RR=9.78).Patients harboring HCMV gN-1 and gN-4 genotypes would seem likely to have 4.6 times of chance leading to AIDS-associated death than those harbo-ring other HCMV gN genotypes.Conclusion HCMV infection ( especially gN-1 and gN-4 genotypes) might accelerate the progression of HIV infection.

Objective To investigate the clinical effect of five-step sequential method for hemorrhagic radiation cystitis.Methods From April 2015 to April 2018,512 cases of hemorrhagic radiation cystitis patients in 6 provincial tumor hospital were retrospectively analyzed.12 cases were male patients,and 497 cases were female.Patients'average age was (60.1 ± 8.2) years (53-71 years).Hematuria appeared in 2.9 years on average after radiotherapy(ranged 0.5 to 13 years).According to the severity of hematuria,480 patients were classified as mild and 32 patients as severe.The step 1 was drug conservative symptomatic treatment.Thrombin solution or sodium hyaluronate was used for bladder perfusion in step 2.The step 3 was transurethral electrocoagulation.The step 4 was interventional embolization.The step 5 was hyperbaric oxygen therapy.Mild patients were treated from the first step,and the severe patients were treated rom step 3,and combined with step 1.Overactive bladder symptom score (OABSS) was used to assess the improvement of patients'symptoms.Results No obvious complications occurred in step 1,2,3,5.Mild hip pain occurred at step 4.Recurrent hemorrhage rate were 6.7％ (2/30) in mild patients group and 10.5％ (2/19) in severe respectively in step 4.The total effective rate of step 1 in mild patients group was 65.2％ (313/480),step 1 + 2 was 84.2％ (404/480),step 1 + 2 + 3 was 95.6％ (459/480),step 1 + 2 + 3 + 4 was 98.3％ (472/480),and step 1 +2 +3 +4 +5 was 100％ (480/480).The effective rate of step 3 + 1 treatment was 59.4％ (19/32) in severe patients group,step 3 + 1 + 4 was 68.8％ (22/32),and step 3 + 1 +4 +5 was 100％ (32/32).The OABSS scores of mild and severe patients decreased after treatment (P＜0.01).Condusion Five-step sequential therapy could be an effective method for the treatment of hemorrhagic radiation cystitis.

Objective:To evaluate the clinical outcomes of additional surgery after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer.Methods:Sixty-nine patients with early gastric cancer who underwent ESD and were diagnosed as having non-curative resection by postoperative pathology at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2014 to December 2020 were included in the retrospective observation. Patients were divided into the additional surgery group ( n=12) and the follow-up group ( n=57). The differences in clinical and pathological data of the two groups, the surgical outcomes of the additional surgery group, three-year recurrence-free survival and tumor-specific survival of the two groups, and the independent risk factors affecting three-year recurrence-free survival in the follow-up group were analyzed. Results:Compared with the follow-up group, the rates of submucosal infiltration [66.7% (8/12) VS 21.1% (12/57), χ 2=7.927, P=0.005], vascular invasion [33.3% (4/12) VS 1.8% (1/57), P=0.003] and nerve invasion [16.7% (2/12) VS 0.0% (0/57), P=0.028] in the additional surgery group were significantly higher. In the additional surgery group, the interval between the additional surgery and ESD was 18.5 d (7-55 d), the surgical time was 286.4±85.9 min, and the number of dissected lymph nodes was 25.6±7.4. Four patients (33.3%) had residual tumor. Postoperative complications occurred in 4 patients (33.3%) (all were discharged after conservative treatment), and there was no perioperative death. One patient developed liver metastases 17 months after the surgery, and died 22 months after surgery due to liver metastases. One patient died 22 months after surgery due to non-tumor causes. The three-year recurrence-free survival and three-year tumor-specific survival in additional surgery group were 91.7% (11/12) and 91.7% (11/12), respectively, and those in the follow-up group were 87.7% (50/57) and 100.0% (57/57), respectively. Multivariate Cox regression analysis showed that tumor size ≥2 cm was an independent risk factor for three-year recurrence-free survival in the follow-up group ( P=0.037, HR=15.595, 95% CI: 1.181-205.952). Conclusion:Additional surgery and close follow-up are safe and feasible therapeutic strategies for early gastric cancer patients who underwent non-curative ESD. Clinicians should make reasonable choice based on the pathological results, patients' physical condition and surgery intention. But for patients with primary tumor size ≥2 cm, additional surgery is recommended.

OBJECTIVETo investigate the efficacy of single-hand four-needle suture with sled-shaped needle three-tail fixed stitch in closure of pesudohernia sac of direct hernia under transabdominal preperitoneal (TAPP) inguinal hernia repair.

METHODSA randomized controlled trail was conducted on adult patients with unilateral direct inguinal hernia undergoing laparoscopic TAPP repair from January 2014 to January 2018 at the Sixth Affiliated Hospital of Sun Yat-sen University. A total of 156 patients were enrolled prospectively in the study and were randomly divided into single-hand four-needle suture group (trial group, 76 cases) and traditional tacking group (control group, 80 cases). In trial group, sled-shaped needle three-tail knot-free stitch was applied to the continuous four-needle suture. The sled-shaped needle three-tail fixed stitch was made as follows: straighten the tail of a 3-0, 1/2-circle looper VICRYL Rapide into a sled shape; use suture overlap method to make and tighten a single knot; thread the end of the needle into the single knot loop;knot two ends of the thread next to the first knot; tighten the second knot, leaving about 12 cm to the end of the needle;cut the end of the loop (leaving about 0.6 cm) and the other end of the thread(leaving about 1.5 cm). In the control group, a hernia repair tack was used to fix the pseudohernia sac on pectineal ligament. This study was approved by the Hospital Ethics Committee(approval number: L2014ZSLYEC-016). Operation time, pseudoherina sac closure time, hospitalization cost, morbidity of postoperative complication, VAS score and postoperative recurrence were compared between two groups.

RESULTSAll the patients completed operations successfully. There were no significant differences between trial group and control group in age [(60.2±0.4) years vs. (61.1±0.7) years)], gender (male ratio 93.4% vs. 92.5%), BMI [(25.1±0.2) kg/m vs. (24.9±0.2) kg/m ], defection area [(16.1±0.4) cm vs. (15.7±0.7) cm ] (all P > 0.05). As compared to control group, trial group had longer operative time[(34.2±1.9) minutes vs. (30.3±1.1) minutes, t=5.484, P=0.045], longer closure time of psudohernia sac [(4.2±0.5) minutes vs. (1.8±0.7) minutes, t=7.423, P=0.031], but lower VAS score (3.2±0.1 vs. 5.3±0.6, t=-3.186, P=0.015) and lower total cost [(9 897.3±104.4) yuan vs. (12 325.6±169.7) yuan, t=-3.972, P=0.023]. No severe complication and death were found in either groups intra-operatively and postoperatively. No mesh infection and relapse occurred during postoperative follow-up of 1-24 (12.0±1.2) months. During follow-up, seroma occurred in 2 cases (2.6%) of trial group and 3 cases (3.8%) of control group without significant difference (χ =1.284, P=0.799), and all were absorbed and disappeared within 30 days after local application of mirabilite.

CONCLUSIONCompared to tack fix method, single-hand four-needle suture with sled-shaped needle three-tail fixed stitch can effectively close pseudohernia sac, reduce hospitalization cost and ameliorate postoperative pain in TAPP repair, which is worth promotion.
