Objective:To analyze the intervention effect of rehabilitation platform-based online psycho-education on patients with bipolar disorder (BD) in remission stage.Methods:In this randomized controlled study, 91 patients with BD in remission stage who attended the community health center in Xicheng District, Beijing from July to August 2021 were randomly divided into a test group (46 cases) and a control group (45 cases) according to a 1∶1 ratio using the random number table. Baseline data were collected from both groups, and the control group received conventional medication and community telephone follow-up, while the test group was given online mental health education in the form of a WeChat subscription number on this basis, including BD mental health education course push (twice a week) and disease self-management (daily recording of mood, sleep, medication, exercise and gratitude diary), and the intervention period was 6 months in both groups. During the intervention, one patient in the test group was admitted to hospital due to exacerbation of mental illness and the trial was terminated. A total of 90 cases were included in the study. The scores of Medication Adherence Rating Scale (MARS), Hamilton Depression Scale (HAMD), Young Mania Rating Scale (YMRS) and Perceived Devaluation-Discrimination Scale (PDD) were assessed at baseline, after 3 months and 6 months of intervention in both groups, respectively. And the differences in baseline data between the two groups were compared using two independent samples t test and χ2 test, and the repeated-measures ANOVA was used to compare the differences in MARS, HAMD, YMRS, and PDD scores between the two groups before and after the intervention, and to analyze the intervention effects of network mental health education based on the rehabilitation platform on patients in remission stage of BD. Results:After 6 months of intervention, MARS scores in the test group was significantly higher than that in the control group [(8.47±1.75) vs (7.47±1.85)], and was significantly higher than that at baseline (7.36±2.13) and after 3 months of intervention (8.04±1.68) (all P<0.05). YMRS and PDD scores in the test group were significantly lower than those at baseline after 3 and 6 months of intervention [YMRS, 2.0(1.0,4.0),2.0(0,3.0) vs 3.0(1.0,5.5); PDD, (31.18±4.65), (30.13±4.76) vs (32.51±4.51)] (all P<0.05); the differences in YMRS and PDD scores in the control group were not statistically significant (all P>0.05). There was no statistically significant difference in HAMD scores between the two groups before and after the intervention (all P>0.05). Conclusion:Combining mental health education based on rehabilitation platform with conventional medication and community management can significantly improve the medication compliance of patients with BD in remission stage, and improve their manic symptoms and reduce the stigma of the disease.

Objective:To explore the relationship between anti-human leukocyte antigen (HLA) antibodies and transplant outcomes in patients with hematological diseases who underwent matched sibling donor transplantation (MSDT).Methods:A retrospective analysis was conducted in 168 patients with hematological diseases who received MSDT in Peking University People's Hospital from March 2015 to November 2017. All patients received detection of anti-HLA antibodies before transplantation, and the correlation between anti-HLA antibodies and transplant outcomes such as hematopoietic cells implantation, blood product transfusion and prognosis after transplantation were analyzed.Results:Among the 168 patients, 28 (16.7%) were positive for anti-HLA class Ⅰ or class Ⅱ antibodies, and 14 (8.3%) were positive for both anti-HLA class Ⅰ and class Ⅱ antibodies. All patients received neutrophil engraftment, 164 patients (97.9%) received platelet engraftment. Univariate analysis showed that there were no effects of anti-HLA antibodies on neutrophil engraftment and engraftment time, platelet engraftment and engraftment time, the volume of red cell transfusion, the volume of platelet transfusion, overall survival (OS) rate, disease free survival (DFS) rate and transplant-related mortality (TRM) in patients with hematological diseases underwent MSDT (all P > 0.05). Multivariate analysis showed that platelet engraftment was associated with better OS ( HR=0.065, 95% CI 0.017-0.252, P < 0.01), better DFS ( HR=0.083, 95% CI 0.024-0.289, P < 0.01) and lower TRM ( HR=0.094, 95% CI 0.014-0.626, P=0.015). Conclusion:Anti-HLA antibodies have no effect on transplant outcomes of patients with hematological diseases who have received MSDT.

Objective: To investigate the functional recovery and cosmetic effects of pre-expanded pedicled deltopectoral flap. Methods: From January 2008 to December 2018, 42 patients with 56 pre-expanded pedicled deltopectoral flaps from Xijing Hospital of Air Force Military Medical University were followed up at least 6 months. 18 of them were male, the remaining were female. And the average age was (24.7±7.3) years. Then the indicators were tested and evaluated. Tubes with different temperatures were used for temperature sensation test. The flaps were stabbed using a 27 G blunt needle to test algesthesia. Tactile threshold was measured by Semmes-Weinstein monofilament. Two-point discrimination was measured by Disk-Criminator. Elasticity of skin flaps was measured by CK-MC®960. Colors of skin flaps were analyzed by ANTERA®3D system, including L^*a^*b^*, melanin and hemoglobin content. And the postoperative scars were evaluated by the Patient and Observer Scar Assessment Scale (POSAS). The flap retraction rate [(flap area immediately after operation-flap area at the follow-up time)/flap area immediately after operation]was calculated. The satisfaction of patients, doctors and third parties was investigated as well. Statistical analysis of data was performed with SPSS 23.0, satisfaction rate was expressed as percentages. Scar scores were compared by Wilcoxon rank sum test. The values of elasticity, color L^*a^*b^*, melanin and hemoglobin between skin flaps and normal skin were analyzed by paired t test. The difference was statistically significant at P<0.05. Results: The scores of pain, heat and cold sensation were (4.61±0.78), (3.48±0.90) and (4.39±0.81), the tactile threshold was (0.26±0.23) g/mm², and the distance of two-point discrimination was (10.09±4.79) mm. There was no significant difference in elasticity, color b^*and melanin content between skin flap and normal skin of face and neck (P>0.05). The color of flap L^*, a^*and hemoglobin content of flaps were significantly different from those of normal skin from face and neck (P<0.05). The result of self-assessment of patients (POSAS) showed that there were significant differences (P<0.05) in pain, itch and stiffness between facial and chest donor scar. The result of observer evaluation (POSAS) showed that the scar score for all items around facial flap was better than that of chest donor area, the difference was statistically significant (P<0.05), and the retraction rate of flaps was (10.44 ±3.36)%. The satisfaction rates of doctors, patients and the third party were 92.86% (39/42), 71.43% (30/42) and 61.90% (26/42), respectively. Conclusions Excellent functional recovery and reliable cosmetic effect were observed in the facial-cervical scar repair with pre-expanded pedicled deltopectoral flap. Transfer of pre-expanded pedicled deltopectoral flap is an effective method for the treatment of facial-cervical scars.

Objective To evaluate the clinical effect of nanofat on superficial rhytides of face and neck and dark lower eyelids.Methods From September 2014 to January 2017,a total of 86 cases were collected in our hospital for voluntary nanofat transplantation on superficial rhytides and dark lower eyelids.This was a retrospective study,which included 18 cases of eye wrinkles,14 cases of forehead wrinkles,neck wrinkles in 14 cases,and 22 cases of dark lower eyelids.First of all,we harvested mircofat through liposuction,and then transformed mircofat to nanofat.At last,nanofat was grafted into intradermal layer of the skin with sharp needles.We took the standard photographs of the patients.After six months follow-up,doctors and patients evaluated the short term and long-term postoperative effect.Results No serious complications occurred in all patients.Postoperative evaluation of facial and neck superficial wrinkles showed that the satisfactory rate of doctors and patients after one month,was 85.9％and 84.3％,and after 6 months 87.5％ and 84.3％,respectively.Postoperative evaluation of dark lower eyelids showed that the satisfactory rate of doctors and patients after one month was 45.5％ and 36.4％,and after 6 months 81.8％ and 86.4％,respectively.Conclusions Nanofat can rectify the superficial rhytides of face and neck and dark lower eyelids in some patients.However,for some patients the effect is not satisfied.

Objective To study the temporal distribution of macrophage and its phenotype markers in fibrous capsules around silicone implants.Methods Thirty rats were randomly divided into five groups:days 1,3,7,14 and 35.Silicone prostheses (10 ml) were implanted subcutaneously into backs of rats.On each indicated day,the tissue specimens were collected,fixed in 4％ paraformaldehyde for 24 hours and embedded in paraffin.Immunofluorescence was used to detect temporal distribution of M1/M2 macrophages.Results The number of CD68+ macrophages at day 1 (65.8±12.9) was smaller than that at day 3 (102.8±14.5,P＜0.05) and day 7 (116.8±14.2,P＜0.05);and the number of CD68+ macrophages at day 7 was larger than that at day 14 (56.8±12.9,P＜0.05) and day 35 (21.40±6.35,P＜0.05);the proportion of iNOS+ CD68+ M1 cells at day 1 and day 3 was 0.48±0.13,0.60±0.13,respectively,and they were higher than that at day 7 (0.21±0.03,P＜0.05),day 14 (0.21±0.03,P＜0.05) and day 35 (0.17±0.04,P＜0.05);the proportions of CD206+ CD68+ M2 cells at day 1,day 3,day 7,day 14,day 35 were 0.70±0.06,0.60±0.07,0.70±0.08,0.67±0.02 and 0.60±0.06,respectively.Conclusions After the implantation of silicone prostheses,M1 cells increase in early stages and M2 cells maintain in high level throughout the experiment period.

Objective: To explore the nipple-areola complex blood supply mode in hypertrophic breasts, and to obtain the pertinent knowledge of vascular anatomy for breast reduction surgery as well as the analysis of similarities and differences between hypertrophic and normal breasts. Comparing the blood supply of nipples-areola complex between these two groups for analyzing their similarities and differences. Methods: Three dimensional reconstruction of the arteries in breast were performed in 50 patients between September 2015 and August 2017 with breast hypertrophy by computed tomographic angiography (CT angiography). The distribution pattern and the source direction of each main blood vessel was observed, counted and analyzed. Then, the data of breast hypertrophy patients were compared with the previous data about nipple-areola blood supply in normal population (the definition of main vessel: entering the breast gland or reaching the nipple-areola surrounding area, and diameter larger than 1 mm). Statistical description was taken for comparison. Results: 135 main vessels were observed in 100 breasts (50 patients). They mainly originate from the internal thoracic artery (69, 51.1%), lateral thoracic artery (37, 27.4%) and thoracoacromial artery(16, 11.9%), as well as a small amount from the brachial artery (7, 5.2%) and axillary artery(6, 4.4%). No main supply vessels from the posterior intercostal artery have been found. The patterns of breast blood supply varied among individuals, and high asymmetry ratio in the same individual was also observed. The internal superior (left: 30.7%, right: 34.2%) and superior lateral quadrant (Left: 29.2%, Right: 20%) of the breast was the most likely area for the main vessel to pass, followed by the breast lateral (Left: 16.9%, Right: 18.5%), lower inner (Left: 4.6%, Right: 5.7%), central (Left: 4.6%, Right: 4.2%), and superior (Left: 1.5%, Right: 2.8%). Differences existed in main vessels between normal breasts and hypertrophic breasts, either for source arteries or the distribution of breast. There was no main blood supply from the intercostal arteries or across the outer inferior quadrant. Conclusions The blood supply of the nipple-areola is not completely consistent between the hypertrophic breast and the normal size breast, and the blood supply pattern of the hypertrophic breasts is complex and diverse. CT angiography might be used before breast reduction surgery for clarifying the direction of the main vessels, so as to preserve more blood supply for nipple-areola, and to prevent nipple-areola necrosis.

Objective To observe the effect of botulinum toxin type A (BTX-A) on the rate of skin expansion and the immediate retract rate of skin flaps in rats,and to explore new methods for drug-assisted skin expansion.Methods 18 Sprague-Dawley rats were randomly divided into two groups.After BTX-A or normal saline was injected intradermally into the back marking area,an expander was implanted.The expanders were inflated periodically by injecting normal saline to reach the designated intraexpander pressure.The inflation volume was recorded and the area of marked region was measured regularly.After 4 weeks of expansion,the expanded tissues were harvested and the immediate retract rates were measured.The hematoxylin-eosin staining was performed to observe the thickness of epidermis,dermis and the fibrous capsule,while Masson staining for detection of fibrous capsule collagen.Immunohistochemical staining with α-smooth muscle actin for myofibroblasts was also performed.Results The mean inflation volume and area of marked region of BTX-A group were significantly greater than those of the control group.There were lower immediate retract rate,thinner fibrous capsule,less collagen content and fewer α-SMA positive myofibroblasts in the fibrous capsule of the BTX-A group with statistically significant differences (P ＜ 0.05).There was no signigicant difference in the thicknesses of epidermis and dermis between the two groups (P＞0.05).Conclusions BTX-A can inhibit the formation of fibrous capsule to promote skin expansion,while reducing the immediate retract rate.It possess a potential for assisting effectively skin expansion.

Objective To investigate the incidence and risk factors of infection in neurosurgical patients in Wuxi people′s hospital,and to provide reference for the prevention of postoperative infection. Methods A total of 53 patients with postoperative infection were collected.The design method of one to three matching case-control study was used controlling age,sex and neurosurgical disease.The risk factors of infection were analyzed by retrospective analysis. Results Among 212 patients, 53 developed infections, the incidence rate was 25.0%(53/212). Respiratory tract infection was the main type of infection (60.4%,32/53).Patients with high blood glucose, high white blood cells, high hemoglobin, preoperative antibiotics in the infection group(t/χ2=3.486, 2.966, 2.196, 30.24, P<0.05). Patients in the infection group had emergency operation,long operation time,intra-operative blood loss,intra-operative blood transfusion(U/χ2=26.39,2.585,3.409,9.792,P<0.05).The infection group patients with postoperative use of antibiotics more than 2 kinds, long hospitalization, The difference between the two groups was statistically significant (U/χ2=85.53, 5.810,P<0.05). Further Logistic regression analysis showed that preoperative high blood sugar, intraoperative blood loss, operative duration and hospitalization time were the risk factors of nosocomial infection. Conclusion Risk factors for infection in department of neurosurgery are multiple and targeted interventions should be taken to reduce postoperative infection rate.
