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.

Objective:To explore the repair methods and effects of refractory wounds in patients after spinal internal fixation operation .Methods:The study was a retrospective observational study. From November 2020 to October 2023, 10 patients with refractory wounds after spinal internal fixation operation were admitted to the Department of Burns and Plastic Surgery of Changde Hospital of Xiangya School of Medicine of Central South University. They were 3 males and 7 females, aged 35 to 68 years. There were 6 cases of thoracolumbar tuberculosis, 3 cases of thoracolumbar fracture, and 1 case of recurrent sacrococcygeal chordoma with skin, soft tissue, and bone defects after radical resection. The wound areas after debridement were 6.0 cm×1.5 cm to 27.0 cm×6.5 cm. The wound repair operation was decided to perform in the primary stage or in the secondary stage according to the wound situation. Two patients with type Ⅰ wounds were treated with debridement, direct suture, and continuous irrigation and drainage with catheter after operation. Eight patients with type Ⅱ wounds were repaired with local flaps (including rotation flap with dermis-fat flap at the end), muscle flaps, or muscle flaps combined with local flaps. The flap sizes were 10.0 cm×5.0 cm to 27.0 cm×14.0 cm, and the sizes of muscle flap were 8.0 cm×5.0 cm×4.0 cm to 17.0 cm×9.5 cm×2.0 cm. The wounds in flap donor areas were sutured directly. The wound treatment methods of patients with type Ⅱ wounds were recorded. The wound healing was observed after operation. The infection and recurrence of wounds, the retention of internal fixation materials, and spinal motor function were observed during follow-up.Results:Among patients with type Ⅱ wounds, there were 3 cases applied with local flaps (including 1 case with rotation flap with dermis-fat flap at the end), 3 cases with muscle flaps (including 1 case with latissimus dorsi muscle flap and 2 cases with erector spinal muscle flaps), and 2 cases with muscle flaps (1 case with latissimus dorsi muscle flap and 1 case with erector spinal muscle flap) combined with local flaps. Only 1 case with secondary defects after radical surgery of sacrococcygeal chordoma had poor wound healing which healed after dressing change, and the wounds of the remaining 9 cases all healed well. During the follow-up of 4 to 18 months, no infection or recurrence of local wounds developed in 10 patients, the internal fixation materials were not loosening, and there was no significant limitation in spinal motor function.Conclusions:For refractory wounds after spinal internal fixation operation, according to the wound type of patients, debridement, suture, irrigation, and drainage in the primary stage, or transplantation of local flaps, muscle flaps, muscle flaps combined with local flaps are performed in the primary stage or in the secondary stage. These methods are proved to have reliable therapeutic effects, not only repairing the wounds, but also retaining the internal fixation materials.

Objective:To explore the strategy of how to select an effective flap for reconstruction of the surgical defect in clavicular region after resection of malignant tumour and care for the aesthetic appearance of the flap donor site.Methods:A retrospective observational study was conducted. Twenty-three patients with soft tissue malignant tumour in clavicle region were treated, from March 2017 to April 2023, in the Department of Burn and Plastic Surgery of Changde Hospital, Xiangya School of Medicine, Central South University (the First People’s Hospital of Changde). The patients were 13 males and 10 females, aged 21 to 72 years old. Ten patients were of dermatofibrosarcoma protuberans, 6 of fibrosarcoma, 3 of squamous cell carcinoma of skin, 3 of undifferentiated pleomorphic sarcoma and 1 of mucinous adenocarcinoma. Nine patients had the first surgery and 14 were with tumour recurrence and had previousely received one or more surgery in other hospitals. The tumour size ranged from 2.0 cm×4.5 cm×1.0 cm to 10.0 cm×16.0 cm×3.0 cm. After radical resection, the sizes of surgical defect ranged from 9.0 cm×12.0 cm to 16.0 cm×22.0 cm. All the clavicular soft tissue malignancies had radical resection, and the secondary surgical defects were further modified to reduce the short and long dimensions of the defects. Flaps were selected according to the short dimension, depth and skin elasticity of the flap donor site. Of the 23 patients, 3 were treated with free inguinal flaps, 9 with ipsilateral pedicled latissimus dorsi flaps or thoracodorsal artery perforator flaps, 5 with free deep inferior epigastric artery perforator flap (DIEPF), 5 with free anterolateral thigh flap (ALTF) and 1 with free rectus abdominis flap. The modified defects sized 5.0 cm × 11.0 cm-12.0 cm×19.0 cm after the suture of margin and base of the defects (defects were reduced and modified). The flap sizes were 7.0 cm×13.0 cm-14.0 cm×23.0 cm. After surgery, the wound healing was observed through the visits of outpatient clinic, and telephone and WeChat interviews. According to the nature of the tumours, the patients were regularly reviewed at outpatient clinic to determine the local recurrence and metastasis of the tumour.Results:One pedicled latissimus dorsi myocutaneous flap was found with a greater tension after surgery. After partial removal of sutures and dressing changes, the secondary suture was performed 1 week later and the wound healed smoothly. A postoperative venous crisis was discovered in a free ALTF. It was monitored and re-anastomosed within 24 hours after surgery, and the flap survived and the wound healed smoothly. Otherwise, the rest of flaps achieved good blood supply and the wounds at the recipient and donor sites healed in one stage. In the postoperative follow-up, all flaps in the clavicular region were found good in appearance with no obvious swelling, and the donor sites healed well without scar contracture or dysfunction. One patient with a squamous cell carcinoma died of lung metastasis at 13 months after surgery. The rest of patients were found no tumour recurrence and had completed postoperative follow-up.Conclusion:After radical resection of malignant soft tissue tumours in the clavicular region, appropriate flaps were selected according to the size (short diameter) and depth of the modified defects, as well as the skin elasticity and relaxation of the flap donor site, hence to facilitate the direct suture of the flap donor site. It not only effectively reconstructs the surgical defect in clavicular region, but also minimises the damage to the flap donor site and achieves an aesthetic appearance at the flap donor site.
