Objective:To explore the latent profile and characteristics of social isolation in patients with hematologic malignancy, and to analyze its related influencing factors, and to provide reference for improving social phobia disorder in different patients and implementing targeted intervention.Methods:This study was a cross-sectional survey. A convenient sampling method was used to select hematologic malignancy patients who were treated in Qilu Hospital of Shandong University from January 2022 to January 2023. General information questionnaire, the General Alienation Scale (GAS), and the Social Support Rating Scale(SSRS) were used for investigation. Latent profile was analyzed using the categories of social isolation in patients with hematologic malignancy, and univariate and multinomial logistic regression analysis were used to analyze relevant influencing factors.Results:A total of 195 survey subjects were included, of which 108 males and 87 females, aged (49.78 ± 13.52) years. The scores of GAS and SSRS were (43.21 ± 6.09) and (42.52 ± 6.77) respectively. The social isolation in patients with hematologic malignancy could be divided into 3 latent profiles, namely low-risk isolation 15.4% (30/195), medium-risk isolation 68.2%(133/195), and high-risk isolation16.4% (32/195). Multinomial Logistic regression analysis showed that age ( OR=0.941, 95% CI 0.894-0.990), percapita monthly income of families ( OR=0.050, 95% CI 0.004-0.657), primary caregivers (parents) ( OR=0.025, 95% CI 0.003-0.227), place of residence (town)( OR=0.170, 95% CI 0.039-0.749), disease type (leukemia) ( OR=15.610, 95% CI 2.973-81.979), disease type(lymphoma) ( OR=10.986, 95% CI 2.032-59.413) were the influencing factors of medium-risk isolation (all P<0.05). Age ( OR=0.933, 95% CI 0.880-0.988), percapita monthly income of families ( OR=0.029, 95% CI 0.002-0.525), primary caregivers (parents) ( OR=0.076, 95% CI 0.006-0.900), disease type (leukemia)( OR=19.257, 95% CI 2.580-143.723), disease type (lymphoma)( OR=9.952, 95% CI 1.290-76.763), social support ( OR=0.877, 95% CI 0.786-0.980) were the influencing factors of high-risk isolation (all P<0.05). Conclusions:The social isolation among patients with hematologic malignancy had apparent classification characteristics. It could be divided into three potential profiles. It is suggested that medical staff should take targeted social and psychological support based on different types of patients, improve their psychological and social outcomes, and utilize existing resources to implement intervention measures to help them adapt and return to society.

〓 Objectives: To analyze the pathological and clinical features of nasal respiratory epithelial adenomatoid hamartoma（REAH）, and summarize the diagnostic points, to improve the experience of diagnosis and treatment. Methods:The clinical data of 16 patients with REAH were analyzed retrospectively. The clinical manifestations, pathological features, imaging features, surgical treatment and prognosis were summarized. Results:16 cases of REAH were studied, 10 cases（62.50%） were associated with sinusitis, 1 case（6.25%） was associated with inverted papilloma, 1 case（6.25%） was associated with hemangioma. 5 cases（31.25%） had a history of nasal sinus surgery, including 1 case with 3 times of nasal sinus surgery, 1 case with 2 times of nasal sinus surgery, 3 cases with 1 time of nasal sinus surgery; 10 cases（62.50%） occurred in the bilateral olfactory cleft, 2 cases（12.50%） in the unilateral olfactory cleft, 3 cases（18.75%） in the unilateral middle turbinate, 1 case（6.25%） in the nasopharynx. All 16 patients were pathologically diagnosed as REAH. In the patients with lesions located in bilateral olfactory fissures, symmetrical widening of olfactory fissures and lateral displacement of middle turbinate were observed on preoperative sinus CT. The average width of bilateral olfactory fissures was （9.9±2.70） mm. The ratio of wide to narrow olfactory cleft was 1.21 ± 0.19. There was no significant difference in Lund-Mackay score between the two sides（P>0.05）. All patients underwent surgery under general anesthesia and nasal endoscopy. The follow-up period ranged from 1 to 66 months, and no recurrence occurred. Conclusion:Preoperative diagnosis of REAH is facilitated by the combination of clinical manifestations and endoscopic and imaging features. Endoscopic complete resection can achieve a good therapeutic effect.

Objective:To evaluate the clinical efficacy of the bridge pedicled transplantation of medial leg fascial flap combined with medial hemisoleus muscle flap for contralateral leg soft tissue defect.Methods:Between January of 2012 and January of 2018, 12 patients with soft tissue defect of the leg were treated with bridge pedicled transplantation of contralateral medial leg fascial flap combined with medial hemisoleus muscle flap by posterior tibial artery. There were 9 males and 3 female, aged from 19 to 53 years (mean, 35 years). The size of the soft-tissue defects ranged from 12 cm×8 cm to 18 cm×9 cm. The immediate coverage of the fascial and muscle flaps and vessel pedicle were repaired by a meshed split-thickness skin graft. The donor site was closed directly. After the transplantation of the one pedicle and two flaps survived, vascular pedicle was cut off.Results:All the fascial and muscle flaps survived completely. No clinical vascular deficiency was found on the fascial and muscle flaps postoperatively. One case developed distal muscle flap small skin graft necrosis, and spontaneous healed after 2 weeks of dressing change. Follow-up period ranged from 2.5 to 4.5 years (mean 3.8 years). A good contour was confirmed both at the recipient and donor sites. Satisfactory clinical results were obtained in this series.Conclusion:This method is suitable for the treatment of soft tissue defects of the leg with only one major blood vessel, which reduces the damage to the donor site.

Objective:To evaluate the efficacy of the repairing anterior tibial adjacent double wounds by transposition with single-pedicle two flaps of the medial head of gastrocnemius.Methods:Between January of 2012 and January of 2018, 10 patients with the anterior tibial adjacent double wounds (7 males and 3 female, aged from 21 to 45 years) were treated by transposition with single-pedicle two flaps of the medial head of gastrocnemius. The size of the soft-tissue defects ranged from 2.0 cm×2.5 cm to 4.5 cm×4.0 cm. The medial head of the gastrocnemius was divided into two flaps with a single pedicle to repair two adjacent wounds of the anterior tibial. The muscle flaps were immediately covered by a meshed split-thickness skin graft, and the wound in donor site was closed directly.Results:All the muscle flaps survived completely. No clinical vascular deficiency was found on the muscle flaps postoperatively. Small wound dehiscence was developed in one patient and spontaneously healed 2 weeks after dressing change. Patients were followed up for 2.0 to 4.5 years. A good contour was confirmed at the recipient and donor sites. Satisfactory clinical results were obtained in this series.Conclusion:This method is suitable for the repair of two adjacent small wounds of the anterior tibial which can reduce the damage to the donor site.

Objective:To summarize the surgical methods and experiences of intra-auditory meningioma, and discuss the techniques achieving complete resection of intra-auditory meningioma by retrosigmoid transmeatal approach on the basis of function reservation of the facial nerve and auditory nerve.Methods:The clinical data of 4 patients with intra-auditory meningioma confirmed by surgery and pathology in Xuanwu Hospital of Capital Medical University and Army General Hospital of People's Liberation Army from January 1998 to December 2018 were retrospectively analyzed. All these 4 patients accepted enlargment of the posterior wall of the internal auditory channel via retrosigmoid transmeatal approach to remove the tumors. The electro-audiogram, surgical records, discharge records and follow-up records were noted.Results:Total resection was achieved in all 4 patients; one was derived from the cerebral dura mater of the outside wall of the internal auditory canal, obtaining radical excision (Simpson grading I resection); the other three were derived from the cerebral dura mater of the internal auditory canal, and the epidural adhesion extended to the ventral internal auditory canal, only receiving Simpson grading II resection. The facial nerve and cochlear nerve in three patients were separated and protected by dissection; while the vestibular nerve and cochlear nerve in the left one patient were not found, and only the facial nerve was dissected and preserved. Two patients with preoperative hearing grading H2 and H3 were able to retain effective hearing after surgery, with postoperative hearing grading H3 and H4, respectively; and the other two patients had postoperative hearing grading H5. Postoperative Karnofsky Performance Scale (KPS) scores were 90 in 3 patients and 70 in one patient. There was no perioperative death.Conclusions:Retrosigmoid transmeatal approach is ideal approach for resection of the intra-auditory meningioma. Surgical excision of intra-auditory meningioma should accept the premise of protecting the facial auditory nerve and aim at extensive resection of tumors, including the dura and bone involved by tumors, so as to reduce the chance of recurrence; and it is necessary to open the width of intra-auditory.

Objective:To compare the efficacy and safety of domestic 16-row and imported 8-row mobile CT in clinics.Methods:A total of 1469 patients accepted domestic 16-row mobile CT head scans (1604 times) from March 2017 to August 2018 in Bayi Brain Hospital Affiliated to 7 th Medical Center of General Hospital of People's Liberation Army and Langfang Aidebao Hospital; and 15510 patients accepted imported 8-row mobile CT head scans (24994 times) from January 2016 to August 2018 in Bayi Brain Hospital Affiliated to 7 th Medical Center of General Hospital of People's Liberation Army. All patients underwent horizontal plain and enhanced head scans, cerebral CT angiography (CTA), and helical 3D imaging; and the imaging quality, operating power consumption, computed tomography dose index volume (CTDIvol) and stability within scanning volume ranges under different scanning modes of the two CT scans were compared. Results:(1) Imaging quality: the horizontal scanning of domestic 16-row mobile CT could clearly display low-density tissues such as the eyeball, optic nerve, brain stem, sulcus and cerebral gyrus; the imaging quality of both CT scans in patients with traumatic subdural hematoma and ischemic stroke completely met the clinical diagnosis and treatment standards. (2) Operating power consumption: the per-hour operating power consumption of domestic 16-row mobile CT ([0.286±0.018] kW·h) was obviously lower than that of imported 8-row mobile CT ([0.485±0.028] kW·h). (3) Radiological hazard: the CTDIvol of the horizontal scanning volume range in domestic 16-row mobile CT ([36.270±0.281] mGy) was significantly lower than that in the imported 8-row mobile CT ([82.520±0.441] mGy, P<0.05); the CTDIvol of enhanced axis scan volume range in the domestic 16-row mobile CT ([36.270±0.335] mGy) was significantly lower than that in the imported 8-row mobile CT ([70.728±0.424] mGy, P<0.05); the CTDIvol in the volume of CTA imaging of domestic 16-row mobile CT ([20.600±0.087] mGy) was significantly lower than that in the imported 8-row mobile CT ([29.300±0.335] mGy, P<0.05). The domestic 16-row mobile CT was designed with shock absorbers and guides; domestic 16-row mobile CT had small load, a low center of gravity, and good stability as compared with imported 8-row mobile CT. Conclusion:In terms of head scanning applications, the imaging quality of domestic 16-row mobile CT and imported 8-row mobile CT is in full compliance with clinical diagnostic standards, but the energy consumption and radiation risk of domestic 16-row mobile CT is significantly lower than imported 8-row mobile CT, enjoying good stability as compared with imported 8-row mobile CT.

Objective:To assess the feasibility of free-handed conical craniotomy and drainage guided by novel 16-slice mobile CT-assisted surface projection in patients with supratentorial intracerebral hemorrhage (sICH), and to evaluate the accuracy of catheter placement.Methods:Fifty-two sICH patients received free-handed conical craniotomy and drainage guided by novel 16-slice mobile CT-assisted surface projection in our hospital from January 2018 to December 2019 were chosen (free-handed conical craniotomy group); 30 sICH patients received frameless stereotactic puncture and drainage at the same time period were selected (stereotactic puncture group). The clinical data of these patients were retrospectively analyzed. The CT results were analyzed, and differences of relative error (RE) as the indicator of catheter placement accuracy were compared between the two groups.Results:Mobile CT was successfully performed in all patients from free-handed conical craniotomy group, and sufficient information was provided for surface projection in all patients. The percentages of patients with satisfactory results of catheter placement (RE<1) in the free-handed conical craniotomy group and stereotactic puncture group were 92.3% and 90.0%; one patients from the free-handed conical craniotomy group had repeated puncture. There was no significant difference in postoperative RE between the two groups (0.52±0.33 vs. 0.53±0.29, P>0.05). Subgroup analysis of different hematoma locations and volumes also showed no statistically significant difference in postoperative RE ( P>0.05). Conclusion:Free-handed conical craniotomy and drainage guided by novel 16-slice mobile CT-assisted surface projection is feasible in sICH patients, and the accuracy of catheter placement is similar with frameless stereotactic puncture and drainage.

Objective To explore the surgical strategy of minimally invasive treatment for acoustic neuroma and to improve the tumor removal rate and facial nerve function preservation rate. Methods Four hundred and fifteen patients suffering from acoustic neuromas, admitted to and treated by minimally invasive surgery via trans-suboccipital retrosigmoid transmeatus approach in our hospital from January 2008 to December 2016, were chosen in our study. Their clinical data were analyzed retrospectively. Postoperative Karnofsky behavioral status scale (KPS) was used to evaluate the prognoses of the patients. Postoperative routine enhanced MR imaging was performed to determine the degrees of tumor resection. Three months after surgery, House-Brackmann facial function grading (H-B) was used to evaluate the facial function of all patients. Results KPS indicated that excellent prognosis was noted in 399 patients (96.10％), good prognosis in 14 (3.37％), and poor prognosis in 2 (0.48％); the larger the tumor diameter, the smaller the proportion of patients with good prognosis. Total resection of the tumors was achieved in 387 patients (93.25％), sub-total resection in 24 (5.78％), and partial resection in 4 (0.96％); the larger the tumor diameter, the smaller the proportion of patients with total resection. There were 398 patients with facial nerve preservation in anatomy, and the anatomic preservation rate of facial nerve was 95.9％; there were 17 without anatomic preservation, and 12 received end to end anastomosis of facial nerve. Three months after operation, H-B grading I-II was noted in 334 patients (80.5％), grading III-IV in 76 patients (18.3％), grading V-VI in 5 patients (1.2％); the larger the tumor diameter, the smaller the proportion of patients with H-B grading I-II. No surgically related deaths occurred. Conclusion Early diagnosis and early microsurgical treatment of acoustic neuroma is helpful in improving the safety and efficacy of tumor resection.

Intracranial venous sinus thrombosis is a special type of cerebral vascular disease. It usually originates from the later period of wasting disease, brain trauma, puerperium, blood disease, heart disease, eye/nasal/facial infection, meningitis and septicemia. It occurs in different age and sex. Infants, young children, frail elderly people, postpartum women, chronic disease patients are prone to be affected.Because of lacking of typical clinical manifestations, the clinical diagnosis and treatment of this disease is difficult and easily leading to misdiagnosis and mistreatment, which affects the prognosis of the patients.Because of lacking of standardized diagnosis and treatment strategy, different methods are needed. According to the proceeding reports, we reviewed the current progress of the diagnosis and treatment of intracranial venous sinus thrombosis.
