Tuberculosis remains a major public health problem. Genetic epidemiological studies have shown that the differences in host genes partly determine the susceptibility to tuberculosis. The occurrence of tuberculosis is the result of the joint action of Mycobacterium tuberculosis and host gene regulation immune response. The study of susceptibility candidate genes has differences in race, population and region, and the study of susceptibility gene polymorphism still has a long way to go in clinical precision diagnosis and treatment. The study and clinical application of mendelian susceptibility to mycobacterial disease can be used as a classic application of precision medical treatment in tuberculosis; although it is a rare case, this model is worthy of reference.
Objective To explore short-term effectiveness of floating island laminectomy surgery in treating thoracic spinal stenosis and myelopathy caused by ossification of the ligamentum flavum. Methods A total of 31 patients with thoracic spinal stenosis and myelopathy caused by ossification of the ligamentum flavum between January 2019 and April 2022 were managed with floating island laminectomy surgery. The patients comprised 17 males and 14 females, aged between 36 and 78 years, with an average of 55.9 years. The duration of symptoms of spinal cord compression ranged from 3 to 62 months (mean, 27.2 months). The lesions affected T1-6 in 4 cases and T7-12 in 27 cases. The preoperative neurological function score from the modified Japanese Orthopaedic Association (mJOA) was 4.7±0.6. Surgical duration, intraoperative blood loss, and complications were recorded. The thoracic MRI was conducted to reassess the degree of spinal cord compression and decompression after operation. The mJOA score was employed to evaluate the neurological function and calculate the recovery rate at 12 months after operation. Results The surgical duration ranged from 122 to 325 minutes, with an average of 204.5 minutes. The intraoperative blood loss ranged from 150 to 800 mL (mean, 404.8 mL). All incisions healed by first intention after operation. All patients were followed up 12-14 months, with an average of 12.5 months. The patients’ symptoms, including lower limb weakness, gait disorders, and pain, significantly improved. The mJOA scores after operation significantly increased when compared with preoperative scores (P<0.05), gradually improving with time, with significant differences observed among 1, 3, and 6 months (P<0.05). The recovery rate at 12 months was 69.76%±11.38%, with 10 cases exhibiting excellent neurological function and 21 cases showing good. During the procedure, there were 3 cases of dural tear and 1 case of dural defect. Postoperatively, there were 2 cases of cerebrospinal fluid leakage. No aggravated nerve damage, recurrence of ligamentum flavum ossification, or postoperative thoracic deformity occurred. ConclusionThe floating island laminectomy surgery is safe for treating thoracic spinal stenosis and myelopathy caused by ossification of the ligamentum flavum, effectively preventing the exacerbation of neurological symptoms. Early improvement and recovery of neurological function are achieved.
Objective To observe the clinical and pathological characteristics of choroidal metastatic carcinoma from lung carcinoma.Methods The clinical and pathological data of 6 patients with choroidal metastatic carcinoma from lung carcinima were analysed retrospectively.Results All the 6 patients had severe visual impairment, including 3 with severe ophthalmalgia. Flat neoplasm were seen in the posterior pole of the eyes in all the 6 patients and retinal detachment were found in 5 patients. Fundus fluorescein angiography (FFA) examination had been performed on 1 patient and blocked fluorescence and hyperfluorescence were seen in the lesion with pinpoint fluorescein leakage loop around it. CT examination had been performed on 3 patients and the shadow of flat homogenous tumor was seen. MRI examination had been performed on 1 patient and high signal intensit ies on T1W and low signal intensities on T2W were found. In all the 6 patients with primary lung carcinoma, 5 were diagnosed with adenocarcinoma and 1 with cellule carcinoma through pathological examination, and 5 patients were diagnosed with choroidal metastatic carcinoma from adenocarcinoma and 1 with choroidal metastatic carcinoma from cellule carcinoma through pathological examination.Conclusion Rapid visual acuity decrease, severe ophthalmalgia, flat neoplasm in ocular fundus and secondary retinal detachment are the main clinical characteristics of the choroidal metastatic carcinoma from lung carcinoma. Most histopathologica l manifestations of the metastatic carcinoma like that of the primary focus, and adenocarninoma is the most common histoclassification. (Chin J Ocul Fundus Dis，2003，19：333-404)
We reported a patient intubated for more than 30 d following brain injury, transferred to our department with tracheocutaneous fistula and a 2 cm fistula between the trachea and the esophagus. We performed tracheal resection and esophageal closure with a latissimus dorsi myocutaneous flap interposed between suture lines. The patient continued mechanical ventilation after surgery and the tracheotomy was achieved 14 d after the beginning of surgical treatment. The patient was started oral feeding and discharged on the 10 d after tracheotomy and referred to a neuromotor recovery clinic for treatment of post-traumatic sequelae.
ObjectiveTo investigate the negative emotions of patients before cardiac surgery in West China Hospital in order to analyze the related factors.MethodsThe Huaxi emotional-distress index (HEI), a screening tool for mood disorders developed by the Mental Health Center of West China Hospital, was used for preoperative psychological evaluation of 1 968 adult patients hospitalized in cardiac surgery from March 2016 to July 2014. There were 835 males and 1 133 females at age of 49±13 years.Results Fifty-one patients (2.6%) had negative emotions, among whom 6 patients were screened for suicide risk. After intervention, none of them had serious consequences caused by adverse emotions, such as automatic discharge from hospital, avoidance of surgery and suicide.ConclusionThis study found that most of the cardiac surgery patients in West China Hospital have good psychological status before surgery, and a few suffered from negative emotions. “Huaxi emotional-distress index” is simple, effective and worth promoting.
Objective To study the ectopic osteogenesis and vascularization ofthe tissue engineered bone promoted by an artificial bone composite that consists of coral hydroxyapatite (CHA), 1,25-(OH)2 D3, human marrow stromal osteoblast (hMSO), and human umbilical vein endothelial cell (hUVEC).Methods After the isolation and the culture in vitro, hMSO and hUVEC were obtained. Then, hMSO (5×105/ml) and hUVEC (2.5×105/ml) were seeded at a ratio of 2∶1 onto the CHA scaffolds coated with 1,25-(OH)2 D3 (the experimental group) or onto the CHA scaffolds without 1,25-(OH)2 D3 (the control group). The scaffolds were culturedin vitro for 3 days, and then the scaffolds were implanted into the pockets that had beenmade on the backs of 18 nude mice. Then, 6 of the mice were implanted with one experimental engineered bone bilaterally; another 6 mice were implanted with onecontrol engineered bone bilaterally; the remaining 6 mice were implanted with one experimental engineered bone and one control engineered bone on each side. At4, 8 and 12 weeks after operation, the retrieved scaffolds and cells were examined by the nake eye and histology as well as by the scanning electron microscopy. The quantitative assessment of the newly-formed bone and the quantitative analysis of the newly-formed blood vessels were performed. Results The evaluationsby the histology revealed that at 4 weeks the original bone tissues grew into the scaffolds in all the groups, but significantly more newly-formed bone tissuesand newly-formed blood vessels were found in the experimental group. At 12 weeks the newly-formed bone tissues were found in all the groups, but there was a typical bone unit found in the experimental group. There was a significantly smaller amount of capillary vessels in the control group than in the experimental group at all the time points. The evaluations by the scanning electron microscopy revealed that at 4 weeks in the experimental group there were great amounts of extracelluar matrix that embedded the cells, and plenty of capillary vessels were found on the surface of the implanted bone materials and some of them grew into the materials; however, in the control group there was a smaller amount of capillary vessels although much extracelluar matrix was still found there. At 8 weeks sarciniform osteoids were found on some of the implanted materials, with much extracelluar matrix and many newly-formed capillary vessels in the experimental group; however, in the control group there were fewer capillary vessels and lower degrees of the bone maturity. The quantitative assessment of the newly-formed bone showed that the newformed bones were 3.1±0.52 in the experimental group but2.30±0.59 in the control group at 8 weeks (Plt;0.05), and 4.63±0.55 vs. 3.53±0.62 at 12 weeks. There was a significant difference at these two time points between the two groups (Plt;0.05). The quantitative analysis of the newly-formed blood vessels showed that the vascular areas were 28.74％±7.81％i n the experimental group but 19.52％±4.57% in the control group at 4 weeks (Plt;0.05), and 24.66％±7.38％ vs. 1784%±5.22% at 12 weeks. There was a significant difference at these two time points between the two groups (Plt;0.05). Conclusion 1,25-(OH)2 D3 as an active factor can increase the interaction between hMSO and hUVEC, and thus promote the ectopic osteogenesis and vascularization in the tissue engineered bone.
Aortic dissection during pregnancy is rare in clinics. Because the symptoms are lack of specificity, early diagnosis is difficult. However, the progression of aortic dissection is fast, therefore, the mortality of pregnant women and fetuses is high, and half of the death in pregnant women is due to aortic dissection. Although the development of medical condition is rapid, aortic dissection of pregnancy is still a great challenge for patients and clinicians, and is one of the most important diseases in obstetric medical disputes. In this paper, combined with the literatures published in recent years, we summarized the epidemiological characteristics and related treatment suggestions of the aortic dissection in pregnancy.
