With the development of interventional therapy technology, trans radial access (TRA) has gradually become the main approach of interventional therapy. Compared with trans femoral access (TFA), TRA has obvious advantages, which can shorten the time of lying in bed and reduce the incidence of complications. However, the radial artery is thinner than the femoral artery, the incidence of spasm is high, and the success rate of puncture is low, so the technical level of operation is required to be high. Nowadays, TRA has been gradually applied to lung cancer, aortic disease, hepatocellular carcinoma, spleen disease, renal artery disease, and other peripheral vascular diseases. With the confirmation of the safety and feasibility of TRA in interventional therapy in different fields, the popularization of TRA in different interventional fields will be supported.

Congenital chest deformity is caused by abnormal development of spine or ribs, resulting in sternal depression or protrusion. Pectus carinatum and pectus excavatum are the most common diseases in clinic, which can either be accompanied by other syndromes or exist alone. The genetic factors of congenital thoracic deformity can be related to single gene mutation, polygene mutation and chromosome aberration. Common clinical congenital thoracic deformity with syndromes, such as Marfan syndrome and Noonan syndrome, often have relatively fixed and clear pathogenic genes. The genetic pathogenesis of non-syndromic and independent congenital thoracic malformations is usually diverse, and treatments for syndromic and non-syndromic congenital thoracic deformity are different. Therefore, it is necessary for us to differentiate syndromic and non-syndromic congenital thoracic deformities in basic research, clinical diagnosis and treatment.
ObjectiveTo summarize the clinicopathological features of microencapsulated/reticular schwannoma.MethodsTwo cases of microencapsulated/reticular schwannoma treated in West China Hospital of Sichuan University were retrospectively collected. The histological and immunohistochemical features were summarized, and the related literatures were reviewed.ResultsTwo cases of microcystic/reticular neurilemmoma diagnosed and treated in West China Hospital of Sichuan University were male. The clinical manifestations were “dull pain in the right lower abdomen” and “mass of left index finger”. Microscopically, the characteristic reticular or cribriform structures were found in all cases, and lymphocytic sheath was seen in 1 case. Immunohistochemical staining showed S-100, glial fibrillary acidic protein (GFAP) and calretinin positive. By February 2020, only 41 cases were reported in the literatures （there were no cases of this group),there was no significant gender difference, the median age was 55 years (11–93 years), and the median size of the lesion was 2.1 cm (0.4–13.0 cm). Most of them were found by accident, without obvious symptoms and signs, and no history of neurofibromatosis type 1 or 2. Microencapsulated/reticular schwannoma in this patients mainly occurs in the viscera, especially in the gastrointestinal tract (mostly in the the colorectal of lower gastrointestinal tract ), most of them were solitary nodular masses without capsule. Microscopically, the boundary was clear, and the characteristic microcapsules and reticular structures were seen. The tumor cells were diffusely expressing S-100 protein, and GFAP and calretinin were expressed in varying degrees. Electron microscopy showed the characteristics of Schwann cells.ConclusionsMicrocystic/reticular schwannoma is a rare subtype of schwannoma, which needs to be differ-entiated from multiple benign and malignant neoplasms. The diagnosis of the tumor is a challenge for the pathologist.
There is increasing evidence that microorganisms play a complex and important role in human health and disease, and that the in vivo microbiome can directly or indirectly affect the host’s immune system, endocrine system, and nervous system. Therefore, a relatively stable equilibrium between the host and the microbiome is crucial in human health. However, in the special pathophysiological state of the perioperative period, preoperative anxiety and sleep deprivation, anesthesia intervention and surgical injury, postoperative medication and complications may all have different effects on the microbial composition of various organs in the body, resulting in pathogenic microorganisms, and the balance between beneficial microorganisms is altered. This may affect patient the outcomes and prognosis in a direct or indirect manner. This paper will provide a systematic review of key studies to understand the impact of perioperative stress on the commensal microbiome, provide a fresh perspective on optimizing perioperative management strategies, and discuss possible potential interventions to restore microbiome-mediated steady state.
ObjectiveTo evaluate the degree of psychological pain for cancer patients undergoing surgical treatment and analyze the contributory factors to provide the theoretical basis for psychological intervention for cancer patients with surgical treatment.MethodsThe clinical data of 455 cancer patients who received surgeries in our hospital from November 2020 to January 2021 were retrospectively analyzed, including 225 males and 230 females aged 53.80±13.50 years. By applying the method of convenient sampling, a cross-sectional survey was carried out by gathering the general information of the patients and evaluating their mental condition with the distress thermometer. The contributory factors were discussed by logistic regression analysis.ResultsThe score for the psychological pain of the patients was 4.11±2.49 points. The main factors contributing to the psychological pain were physical problems, emotional problems and family matters. The logistic regression analysis showed that the main factors related to the degree of psychological pain were cancer types (P=0.023), religious belief (P=0.046), number of niduses (P=0.016), respiratory status (P=0.004), medical expense (P=0.007), grief (P=0.001) and anxiety (P=0.040).ConclusionNearly half of the patients have been subjected to apparent psychological pain, and emotion and physical problems are the main factors. It is crucial to pay attention to the patients’ mental problems, seek convenient tools for psychological evaluation, and take actions to deal with the psychological problems and physical symptoms.
Objective To investigate the method and the short term cl inical effectiveness of in situ suture repair procedure of knee dislocation with multi ple-l igament injury at acute stage. Methods From February 2006 to November 2007, 9 patients suffering from single knee closed dislocation with multi ple-ligament injury underwent open in situ suture repairprocedure with non-absorbable thread and managements of other combined injuries simultaneously. Nine patients included 6 males and 3 females, aged 34-52 years old. The injured knees were left side in 4 cases and right side in 5 cases. Injuries were caused by traffic accident in 8 cases and heavy-weight crushing in 1 case. EMRI and arthroscopic examination showed that all patients suffered from the avulsion injuries of anterior cruciate l igament and posterior cruciate l igament. The time from injury to operation was 4 to 7 days with an average of 5.1 days. Results No bacterial arthritis occurred after operation. Subcutaneous liquated fat occurred and cured after symptomatic treatment in 2 cases, other incisions healed by first intension. All patients were followed up 12 months. At 12 months postoperatively, 2 patients’ flexion range of the suffering knees lost 10° when to compared with normal knees, and the range of motion was from 0 to 125°. The Lysholm knee scores were 83-92 (average 86.3), the results were excellent in 3 cases and good in 6 cases. The posterior drawer test and anterior drawer test were one-degree positive in 3 cases respectively; the Lachman tests were one-degree positive in 5 cases, lateral stress tests were negative in all cases. Conclusion In situ suture repair procedure of knee dislocation with multi ple-ligament injury at acute stage has the advantages such as rel iable fixation, simultaneous management of other combined injuries and satisfactory short term effect.

Methods A total of 23 patients (28 knees) with synovial chondromatosis were diagnosed and treated in our hospital from January 2005 to October 2009. All of the patients underwent radiographic imaging examination, knee joint range of motion (ROM), visual analogue scale (VAS) and Lysholm score. According to distinct arthroscopic appearance, superficial pattern was found in 6 patients and loose body lesion pattern was in 17. Additionally, combined with pathological examination, according to the Milgram staging，Stage Ⅱ was in 6 patients and Stage Ⅲ was in 7. Arthroscopic limited synovectomy and removal of loose bodies were performed on all the patients. Results The patients were followed up for 13-57 months with the mean of (32.3±6.7) months. The wound of all patients healed up. The time of returning to normal work and life was (5.05±2.43) days for average. The postoperative symptom was markedly alleviated in 21 patietns and partly alleviated in 2. All patients were satisfied with the therapeutic effect. The mean activity of knee joint was significantly different befoe and after the surgery (Plt;0.05) preoperative extension and flexion degrees were (14.29±16.34) and (106.07±35.83) degrees, respectively; postoperative extension and flexion degrees were (1.79±2.79) and (132.64±35.64) degrees (flexion) , respectively. The mean VAS score of weight bearing walking was 0.37±0.65 after theoperation and 3.81±2.02 before the peration; the difference was significantly different (Plt;0.05). The preoperative Lysholm knee score was 34-67 with the mean of 43.20±8.24, and the post-operative score was 71-99 with the mean of 86.72±5.40. There were differences in preoperative and post-operative scores (Plt;0.05) . Radiographic imaging examination of knee joint was performed 1 year after the opertation, no loose bodies was seen and no patients recurred. Conclusion The therapeutic effect of arthroscopic limited synovectomy and removal of loose bodies is good on synovial chondromatosis.
Objective To compare the effect of proximal femoral nail anti-rotation (PFNA) and dynamic hip screw (DHS) in the treatment of intertrochanteric fracture in elderly patients with osteoporosis. Methods A total of 72 elderly patients with intertrochanteric fractures were enrolled between December 2011 and December 2014. According to the different surgical methods, the patients were divided into PFNA group (38 cases) and DHS group (34 cases). The operation time, perioperative blood loss, postoperative weight-bearing time, Harris score were compared between the two groups. Results All cases were followed up for 5–24 months (mean, 13.5 months). The operation time in PFNA group was shorter than that in DHS group [(40.25±24.23) vs. (72.65±34.65) minutes], the perioperative blood loss in PFNA group was less than that in DHS group [(136±56) vs. (256±102) mL], the postoperative weight-bearing time in PFNA group was earlier than that in DHS group [(5.24±4.52) vs. (15.69±6.78) days], and the Harris score in PFNA group was higher than that in DHS group (80.23±10.26 vs. 54.75±12.37) ; the differences above were all statistically significant (P<0.05). Conclusion Elderly patients with intertrochanteric fracture and osteoporosis treated with PFNA have shorter operation time, less wounds, better hip function, and earlier weight-bearing than the patients treated with DHS; the surgical method can improve the patient′ life quality.
Objective To establish a predictive model for long-term tumor-specific survival after surgery for patients with intermediate to advanced medullary thyroid cancer (MTC) based on American Joint Committee on Cancer (AJCC) TNM staging, by using the Surveillance, Epidemiology, and End Results (SEER) Database. Methods The data of 692 patients with intermediate to advanced MTC who underwent total thyroidectomy and cervical lymph node dissection registered in the SEER database during 2004–2017 were extracted and screened, and were randomly divided into 484 cases in the modeling group and 208 cases in the validation group according to 7∶3. Cox proportional hazard regression was used to screen predictors of tumor-specific survival after surgery for intermediate to advanced stage MTC and to develop a Nomogram model. The accuracy and usefulness of the model were tested by using the consistency index (C-index), calibration curve, time-dependent ROC curve and decision curve analysis (DSA). Results In the modeling group, the multivariate Cox proportional hazard regression model indicated that the factors affecting tumor-specific survival after surgery in patients with intermediate to advanced MTC were AJCC TNM staging, age, lymph node ratio (LNR), and tumor diameter, and the Nomogram model was developed based on these results. The modeling group had a C-index of 0.827 and its area under the 5-year and 10-year time-dependent ROC curves were 0.865 [95%CI (0.817, 0.913)], 0.845 [95%CI (0.787, 0.904)], respectively, and the validation group had a C-index of 0.866 and its area under the 5-year and 10-year time-dependent ROC curves were 0.866 [95%CI (0.798, 0.935)] and 0.923 [95%CI (0.863, 0.983)], respectively. Good agreement between the model-predicted 5- and 10-year tumor-specific survival rates and the actual 5- and 10-year tumor-specific survival rates were showed in both the modeling and validation groups. Based on the DCA curve, the new model based on AJCC TNM staging was developed with a significant advantage over the former model containing only AJCC TNM staging in terms of net benefits obtained by patients at 5 years and 10 years after surgery. Conclusion The prognostic model based on AJCC TNM staging for predicting tumor-specific survival after surgery for intermediate to advanced MTC established in this study has good predictive effect and practicality, which can help guide personalized, precise and comprehensive treatment decisions and can be used in clinical practice.
