Objective To explore the new operation approach and the effect of surgical therapy on cardial carcinoma. Methods A total of 78 patients with cardial carcinoma received surgical therapy by the transabdominal route from January 1992 to January 2002, of which 30 cases were treated by total gastrectomy by substitution of P shaped jejunum and 48 cases were treated by subtotal gastrectomy. All patients were followed-up postoperatively from 6 months to 5 years. Results The average length of resected lower part of the esophagus above the tumors was over 5cm, without cancer tissue retained in resected edge. The rate of intramediastinal lymph node metastasis was 18.4%. 5-year survival rate of the patients with total gastrectomy was higher than that of the patients with subtotal gastrectomy, and the morbidity rate of reflux esophagitis of the former was lower than that of the latter. Conclusions The patients of cardial carcinoma in Ⅲ stage or Ⅱstage with lymph node metastasis of 5 or 6 groups should be treated by radical total gastrectomy. The P shaped reconstruction of stomach with jejunum as a replacement satisfies the physiological needs and causes less compications.

Objective: To investigate the clinicopathologic features, immunophenotype, pathological diagnosis and treatment of malignant mixed tumor (MMT). Methods: Clinical and pathological features including immunohistochemical phenotypes were analyzed in a case of MMT accompanied with eccrine porocarcinoma (EP) involving both hands, diagnosed definitely in January 2018 along with review of relevant literature. Results: A 64-year-old man presented with multiple rash on both hands for 4 years. Three lesions of 0.5 to 2.2 cm were removed for pathological evaluation. The pathological changes on little finger of left and right hands were MMT with EP, whereas that removed from the right ring finger was EP. MMT showed infiltrative growth with vascular wall invasion and consisted of epithelial (glandular or tube differentiation) and mesenchymal components (mucinous and/or cartilage stroma). The endothelial cells showed moderate to severe cytological atypia, nuclear pleomorphism and increased mitotic activity. The glandular component had histological characteristics of syringocarcinoma with moderately atypical chondrocytes but without myoepithelium. EP was composed of basal cells with visible vacuoles in cytoplasm and the presence of tubular and squamous differentiation, along with obvious atypia. Immunohistochemically cavosurface epithelium of glandular differentiation of MMT showed positivity for CK7, EMA and CD117. Myoepithelium showed S-100, CK5/6 and p63 positivity and stromal cells were positive for S-100. Differential diagnoses included metaplastic carcinoma, malignant myoepithelioma and atypical mixed tumor of skin. Conclusions MMT with EP is extremely rare.The diagnosis of MMT depends on the morphologic features. Immunohistochemical staining is helpful for differential diagnosis. Surgical excision with safety margins is the treatment of choice. Complementary radiotherapy and/or chemotherapy is still controversial. The clinical course of MMT is deemed unpredictable and long-term follow-up is necessary.

Objective:To analyze the application value of metagenomic next-generation sequencing (mNGS) in the detection of pathogenic bacteria in brain abscesses.Methods:The data of patients with brain abscess in Tianjin Huanhu Hospital from January 2019 to December 2021 were retrospectively analyzed. All patients underwent stereotaxic abscess puncture and drainage. According to the different methods of pathogen detection, they were divided into bacterial culture group (bacterial culture only) and mNGS group (bacterial culture with mNGS). The clinical symptoms, abscess site, bacterial culture and mNGS results, antibiotic application protocol and prognosis of the patients were analyzed. The bacterial detection results of the two groups were analyzed, and the antibiotic application and prognosis were compared. χ 2 test, exact probability method and Mann Whitney test were used to compare the difference between the two groups. Results:A total of 43 patients with brain abscess were enrolled, including 21 cases in bacterial culture group and 22 cases in mNGS group. The positive rate of bacteria culture group was 42.9% (9/21), the positive rate of bacteria culture group was 45.5% (10/22), and the positive rate of mNGS detection was 100% (22/22). Only 3 cases in the bacterial culture group could have a clear bacterial source, while 17 cases in the mNGS group could have a clear bacterial source according to the bacterial results, showing a significant statistical difference between the two groups (χ 2=19.69, P<0.001). The return time of bacterial culture was 7.0 (4.0,7.0) days, and the average return time of mNGS was 1.5 (1.5,1.5) days, the difference of bacterial return time between the two groups was statistically significant ( Z=0.00, P<0.001). The cost of antibiotic use in bacterial culture group was 24.00 (5.60,31.00) thousands yuan, and the cost of antibiotic use in mNGS group was 12.00 (2.10, 20.00) thousands yuan, and there was significant statistical difference between them ( Z=5.22, P=0.026). Conclusions:MNGS can quickly and accurately identify the types and sources of brain abscess pathogens, guide the clinical application of antibiotics more targeted, reduce the cost of antibiotic use, and is an effective method for the detection of brain abscess pathogenic bacteria.

Objective:To investigate the clinical manifestations, pathogenesis,diagnosis and treatment of negative pressure hydrocephalus (NPH).Methods:A retrospective analysis was performed on the 5 patients with NPH admitted to the Department of Neurosurgery, Tianjin Huanhu Hospital from January 2019 to December 2021. All of the patients underwent lumbar puncture and ventricular puncture to test the pressure. Three patients underwent endoscopic third ventriculostomy (ETV), the outcome of the patients was observed.Results:The pressure of subarachnoid was not equal to intraventricular, and the pressure of intraventricular was negative. Cisternography showed cerebrospinal fluid circulation obstruction in all 5 cases. The symptoms of 1 patient were improved after external negative pressure drainage, 3 patients were improved after further ETV and 1 patient had pulmonary infection without further surgical treatment.Conclusion:With the obstruction of cerebrospinal fluid circulation, the pressure of lateral ventricle and subarachnoid is different, when the pressure of brain or subarachnoid drop, the ventricular expansion under the effect of pressure gradient, intraventricular pressure drop even for the negative pressure. CT cisternography provides strong evidence for the diagnosis of this disease. External ventricular drainage with negative pressure and ETV are effective treatment methods.

Objective:To compare the clinical outcomes of arthroscopic external tension band fixation versus open reduction and internal fixation in the treatment of greater tubercle fracture of the humerus.Methods:A retrospective cohort study was conducted on 55 patients with greater tubercle fracture of the humerus admitted to Taizhou Hospital of Zhejiang Province from September 2019 to June 2022, including 24 males and 31 females, aged 26-80 years [(61.7±10.5)years]. Out of them, 35 patients treated with open reduction and internal fixation (open reduction group), and 20 patients were treated with external anchor tension band under arthroscopy (arthroscopy group). The operation time, and the Visual Analogue Scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score and shoulder active range of motion (anterior flexion, abduction and posterior extension) before operation, at 1 month after operation and at the last follow-up were compared between the two groups. Bone healing was observed in both groups at the last follow-up. Postoperative complications were compared between the two groups.Results:All the patients were followed up for 12-29 months [(16.9±4.0)months]. There was no significant difference in operation time between the two groups ( P>0.05). There were no significant differences in the VAS score, ASES score, Constant-Murley score and shoulder active range of motion between the two groups before operation ( P>0.05). The VAS score of the arthroscopy group was 3(2, 3)points at 1 month after operation, which was significantly lower than that of the open reduction group [4(3, 4) points] ( P<0.01). No significant difference was found in the VAS score at the last follow-up between the two groups ( P>0.05).The ASES scores of the arthroscopy group were (70.6±4.2)points and (90.2±3.7)points at 1 month after operation and at the last follow-up respectively, which were significantly higher than those of the open reduction group [(64.7±6.4)points and (87.5±4.9)points respectively] ( P<0.05 or 0.01). There was no significant difference in the Constant-Murley score between the arthroscopy group [(71.8±4.3)points] and the open reduction group [(70.9±5.3)points] at 1 month after operation ( P>0.05), while the Constant-Murley score of the arthroscopy group was (94.1±3.1)points at the last follow-up, which was significantly higher than that of the open reduction group [(89.2±4.7)points] ( P<0.01). At 1 month after operation and at the last follow-up, ranges of motion of the anterior flexion, abduction and posterior extension were (52.7±12.3)° and (140.0±16.9)°, (57.4±8.6)° and (125.0±14.3)°, and 16(15, 19)° and 25(20, 30)° in the arthroscopy group respectively, which were significantly higher than those in the open reduction group [(42.2±5.2)° and (110.9±14.0)°, (52.8±6.0)° and (103.7±11.7)°, and 10(10, 20)° and 16(15, 25)° respectively] ( P<0.05 or 0.01). At the last follow-up, it was found that bony union was achieved in both groups. There were no obvious complications such as incision infection or joint stiffnessin both groups. In the open reduction group, 2 patients had internal fixation failure within 1-3 months after operation but was treated with revision operation; 6 patients developed shoulder stiffness at 3-6 months after operation but had outpatient rehabilitation. The incidence rate of postoperative complications in the arthroscopy group [0%(0/20)] was significantly lower than that in the open reduction group [23%(8/35)] ( P<0.05). Conclusion:Compared with open reduction and internal fixation with plates and screws, arthroscopic external anchor tension band fixation in the treatment of greater tuberosity fracture of the humerus has the advantages of earlier pain relief, better shoulder functional improvement, better recovery of shoulder mobility, and fewer complications.

The theory of "yang transforming qi and yin shaping up body" comes from Huangdi Neijing (Inner Canon of Yellow Emperor),which describes the basic form of human metabolism dominated by "yang transforming qi":the effect of " yang transforming qi" leads the energy metabolism of human body,while the effect of "yin shaping up body" leads the material metabolism. Metabolic syndrome is a clinical syndrome with metabolic disorders of protein,fat and carbohydrate. The theory of "yang transforming qi and yin shaping up body" has a strong guiding value for the pathogenesis analysis and clinical differentiation and treatment of metabolic syndrome. Yin and yang represent the two basic trends of the change and development of things,and the functions of "transforming qi" and "shaping up body" are the main manifestations of them in metabolism. From this perspective,this paper suggests that the key pathogenesis of metabolic syndrome should be "insufficiency of yang transforming qi and impairment of yin shaping up body" based on the mutual assistance of yin and yang. On this basis we take "coordinating yin-yang and promoting the reproduction of them" as the main directions of therapy,which provides a new idea for the treatment of metabolic syndrome.

Objective:To assess the efficacy of modified arthroscopic lower trapezius transfer with autologous hamstring tendon bridging for irreparable massive posterosuperior rotator cuff tears.Methods:A retrospective analysis was conducted on 59 patients (11 males and 48 females; mean age 66.70±6.10 years, range 55-79 years) treated between June 2019 and November 2022 for posterior superior irreparable massive rotator cuff tears. The treatment involved total arthroscopic oblique muscle transposition combined with partial rotator cuff repair. Shoulder mobility was measured in active supination, forward flexion, posterior external rotation, and abduction external rotation before surgery and at the final follow-up. The Constant-Murley shoulder function score, visual analogue scale (VAS) for pain, and American Shoulder and Elbow Surgeons (ASES) scores were assessed preoperatively, at 3 months, 6 months postoperatively, and at the final follow-up. MR examinations were conducted preoperatively and at 3, 6, and 12 months postoperatively to evaluate rotator cuff healing and retear rates.Results:All surgeries were successfully completed using an average of 3.2±0.5 anchor nails (range 3-5) per case. The mean follow-up period was 15.9±5.7 months (range 12-37 months). Significant improvements in shoulder mobility were observed postoperatively compared to preoperative measurements. The mean body external rotation angle increased from 12.0°±19.4° preoperatively to 35.3°±19.6° at the final follow-up ( P<0.05), and the mean abduction external rotation angle increased from 33.4°±22.4° to 43.4°±23.1° ( P<0.05). The mean preoperative abduction angle improved from 121.7°±47.9° to 136.4°±40.6° ( P<0.05), and the mean forward flexion supination angle improved from 117.6°±45.8° to 139.5°±33.7° ( P<0.05). Postoperative VAS scores significantly improved from 4.8±1.8 preoperatively to 0.3±0.8 at the final follow-up ( F=104.868, P<0.001). The ASES scores improved from 42.0±14.9 preoperatively to 71.7±14.6 at the final follow-up ( F=47.287, P<0.001). The Constant-Murley scores increased from 54.3±17.1 preoperatively to 76.4±13.0 at the final follow-up ( F=44.082, P<0.001). Postoperative complications included 2 complete tears and 7 partial tears (re-tear rate 15.3%). No serious complications such as shoulder joint infection, joint stiffness, or vascular nerve injury were observed. One patient developed a localized subcutaneous hematoma at the tendon extraction site, and another developed deep vein thrombosis of the lower extremity, which improved with symptomatic anticoagulation. Conclusion:Modified arthroscopic lower trapezius transfer with autologous hamstring tendon bridging effectively reduces shoulder pain, improves shoulder joint activity and function scores, and is associated with a low rate of surgical complications for patients with irreparable massive posterosuperior rotator cuff tears.

Objective:To analyse the clinical efficacy of arthroscopic double-bundle Endobutton fixation of the thin bone channel in the treatment of Rockwood type III-V acromioclavicular joint dislocation.Methods:A total of 34 patients with acromioclavicular joint dislocation, 24 males and 10 females, aged 50.9±11.0 years (range, 21-74 years), who underwent arthroscopic double-bundle Endobutton fixation of the thin bone channel at Zhejiang Province Taizhou Hospital, Wenzhou Medical University, from February 2015 to February 2022 were retrospectively analyzed. There were 24 cases on the left side and 10 cases on the right side. Causes of injury: 23 cases of car accident, 7 cases of fall, 4 cases of falling from height. Rockwood classification: Type III 17 cases, type IV 9 cases, type V 8 cases. The visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, and joint range of motion were used to evaluate shoulder pain and functional improvement.Results:All patients successfully completed the operation and were followed up for an average of 16.6±2.8 months (range, 12-24 months). Postoperative VAS scores were significantly lower compared to preoperative scores ( F=199.408, P<0.001), with the final follow-up VAS score being 1.32±0.47, significantly lower than the preoperative score of 4.71±1.19 ( P<0.001). Postoperative ASES scores were significantly higher compared to preoperative scores ( F=335.838, P<0.001), with the final follow-up ASES score being 88.85±6.41, significantly higher than the preoperative score of 34.76±5.79 ( P<0.001). The Constant-Murley scores of 3 months, 6 months after operation and the last follow-up were 77.79±5.34, 87.40±5.19 and 88.17±4.40, respectively, which were higher than that before operation 37.41±6.52, and the difference was statistically significant ( P<0.05). At the final follow-up, shoulder flexion, adduction, and abduction were 172.9°±6.4°, 59.2°±6.2°, and 59.3°±5.9°, respectively. The coracoclavicular distance was 1.76±0.42 mm, 0.84±0.19 mm, and 0.87±0.18 mm before operation, 3 months after operation, and at the last follow-up, respectively, and the difference was statistically significant ( F=101.160, P<0.001). Whereas, 3 months postoperative and the final follow-up were smaller than the preoperative ones, and the difference was statistically significant ( P<0.05). All incisions healed in one stage, and there was no vascular or nerve injury, internal fixation infection, coracoid process or clavicle bone tunnel fracture, or internal fixation loosening or breakage. Conclusion:Arthroscopic double-bundle Endobutton fixation with thin bone channel for the treatment of Rockwood type III-V acromioclavicular joint dislocation can improve shoulder function and reduce pain, with high surgical safety.
