Objective To investigate the relationship between serum interleukin-1β(IL-1β),C-reactive pro-tein to albumin ratio(CAR)and heparin-binding protein(HBP)levels and secondary pulmonary Candida albi-cans infection during chemotherapy in patients with lung cancer.Methods A total of 175 patients with lung cancer admitted to this hospital from January 2018 to April 2022 were selected,and all patients were treated with chemotherapy.According to whether they had secondary pulmonary Candida albicans infection,they were divided into infection group(37 cases)and non-infection group(138 cases).The clinical data,serum levels of IL-1β,HBP and CAR were compared between the two groups.Multivariate Logistic regression analysis was used to analyze the influencing factors of secondary pulmonary Candida albicans infection in patients with lung cancer during chemotherapy.The receiver operating characteristic(ROC)curve was used to analyze the pre-dictive value of serum IL-1β,CAR and HBP for secondary pulmonary Candida albicans infection during chemo-therapy,and the prognosis of lung cancer patients with different serum IL-1β,HBP levels and CAR were com-pared.Results There were significant differences in smoking,pathological stage,diabetes mellitus,chemo-therapy cycle,chronic obstructive pulmonary disease and anatomical location between the infection group and the non-infection group(P＜0.05).The serum levels of IL-1β,HBP and CAR in the infection group were higher than those in the non-infection group(P＜0.05).Multivariate Logistic regression analysis showed that smoking,diabetes,anatomical site,chronic obstructive pulmonary disease,pathological stage,chemotherapy cycle and serum IL-1β,HBP,CAR were the influencing factors of secondary pulmonary Candida albicans infec-tion in patients with lung cancer during chemotherapy(P＜0.05).The area under the curve(AUC)of serumIL-1β,CAR and HBP in predicting pulmonary Candida albicans infection was 0.779,0.732 and 0.796,respec-tively.The AUC of the combination of the three was 0.931,and the sensitivity and specificity were 86.49％and 90.58％,respectively.The survival rate of lung cancer patients with high levels of IL-1β,CAR and HBP was sig-nificantly lower than that of patients with low levels of Il-1β,CAR and HBP(P＜0.05).Conclusion The in-crease of serum IL-1β,CAR and HBP levels in patients with lung cancer is related to secondary pulmonary Candida albicans infection during chemotherapy.Detection of these serum Il-1β,CAR and HBP levels is helpful to predict the risk of pulmonary Candida albicans infection and death.

Contemporary college students have low levels of health literacy, facing problems such as weak awareness of health care, unhealthy diet habits, insufficient physical activity, and inadequate emergency response to public health emergencies. The reasons may be related to weak personal awareness of health literacy, imperfect health education system, shortage of health literacy education talents, lack of family health literacy education, and the insufficient social investment in health literacy cultivation. Faced with this current situation, the government, universities, families, individuals, and society should respond to the call of "Healthy China 2030" Plan Outline, regard improving college students’ health literacy level as their own responsibility, help them eliminate or reduce the risk factors affecting health, improve their health literacy level and quality of life, and contribute to the Healthy China strategy.

Objective:To investigate the factors affecting phenotypes in the patients of methylmalonic acidemia combined with homocysteinemia cblC type with MMACHC c. 609G>A homologous variant. Methods:A retrospective study on the clinical manifestations, complications, treatment, and outcome in 164patients of cblC type with MMACHC c. 609G>A homologous variant was conducted.The patients were diagnosed by biochemical and genetic analysisfrom January 1998 to December 2020. Results:Among the 164 patients, 2 cases were prenatally diagnosed and began treatment after birth. They are 3 and 12 years old with normal physical and mental development. Twenty-one cases were diagnosed by newborn screening. Among them, 15 cases had with normal development. They were treated fromthe age of two weeks at the asymptomatic period. Six cases began treatment aged 1 to 3 months after onset. Their development was delayed. One hundred and forty-one cases were clinically diagnosed. Their onset age ranges from a few minutes after birth to 6 years old. 110 cases had early-onset (78.0%). 31 cases had late-onset (22.0%). Five of them died. 24 patients lost to follow-up. Of the 141 clinically diagnosed patients, 130 (92.2%) with psychomotor retardation, 69 (48.9%) with epilepsy, 39 (27.7%) with anemia, 30 (21.3%) had visual impairment, 27 (19.1%) had hydrocephalus, 26 (18.4%) had feeding difficulties, 7 (5.0%) with liver damage, and 5 (3.5%) with metabolic syndrome. The frequency of hydrocephalus and seizures was significantly higher in the early-onset group. The urinary methylmalonic acid increased significantly in the patients with epilepsy. During the long-term follow-up, the level of plasma total homocysteine in the seizure-uncontrolled group was significantly higher than that in the seizure-controlled group, the difference had a statistical significance ( P<0.05). Conclusion:Most of the patients with MMACHC c. 609G>A homozygous variant had early-onset disease, with a high mortality and disability rate. If not treated in time, it will lead to neurological damage, resulting in epilepsy, mental retardation, hydrocephalus, and multiple organ damage. Pre-symptomatic diagnosis and treatment are crucial to prevent irreversible neurological damage. Neonatal screening and prenatal diagnosis are important to improve the outcome of the patients.

Objective:To evaluate the clinical effect of ultrapulse fractional CO 2 laser in the treatment of mild to moderate orbital aging in Asians. Methods:From January 2018 to December 2018, 36 patients (72 eyes) with mild to moderate orbital aging were enrolled, 22 women and 14 men, with an average age of 32.4 years. Each patient was randomly divided into two groups. In the traditional operation group, 36 eyes received blepharoplasty through traditional inferior conjunctival approach. In the ultrapulsed fractional CO 2 laser group, 36 eyesunderwent blepharoplasty through the lower eyelid conjunctival approach assisted by optoelectronics. Both groups were treated with ultrapulsed fractional CO 2 laser for periorbital aging. The operation time, detumescence time and postoperative complications were compared. At the same time, the periorbital skin relaxation was treated by the combination of the two groups. The patients were followed up for 12 months. Results:In the traditional operation group, 11 cases were evaluated as Barton grade Ⅰ preoperatively, and the efficacy score was 0.64±0.21. In 25 cases of Barton grade Ⅱ the efficacy score was 1.34±0.34. 17 cases were Barton Ⅰ in photoelectric assisted group, and the efficacy score was 0.92±0.18. In 19 cases of Barton grade Ⅱ, the efficacy score was 1.71±0.42. There was a statistically significant difference between the two groups in Barton Ⅰ efficacy score, P<0.05 ( P=0.016); There was also a statistically significant difference between the two groups in efficacy score of Barton Ⅱ, P<0.05 ( P=0.039). The operation time of the photoelectric assisted group was (12.00±1.82) minutes, and the edema duration was (4.0±1.8) days. The duration of operation in the conventional surgery group was (16.00±3.75) minutes, and the duration of edema was (7.0±2.4) days. The operation time and edema duration in the photoelectric assisted group were both shorter than those in the traditional operation group, and the differences were statistically significant ( P<0.05). Conclusions:The blepharoplasty through traditional inferior conjunctival approach assisted with ultrapulsed fractional CO 2 laser has no obvious bleeding, with shorter operation time, swelling reduction time and the number of complications than the traditional operation.This method can solve the symptoms of blepharoplasty, lower eyelid skin relaxation and wrinkles around eyes. This method is worthy of promotion in the treatment of patients with mild to moderate periorbital aging.

Objective:To explore the clinical effects of pre-expanded anterior perforator flap of transverse cervical artery in extensive facial and cervical scar reconstruction and contralateral pre-expanded thoracic random flap in relay in donor site repair.Methods:A retrospective cohort study was conducted. From May 2008 to December 2018, 10 patients with extensive facial and cervical scar after burns were treated in the Fourth Medical Center of PLA General Hospital, including 8 males and 2 females, aged 10-55 years. In the first stage of operation, two skin and soft tissue expanders of the same volume (with rated capacity of 250-600 mL) were respectively placed in the right side and left side of the chest according to the size of scar, and then the skin was expanded. The total amount of normal saline injected was 2 to 4 times of the rated capacity of the expander. In the second stage, the defect with area of 12 cm×8 cm-23 cm×15 cm caused by scar resection and release was repaired with unilateral pre-expanded anterior perforator flap of transverse cervical artery with area of 12 cm×9 cm-24 cm×16 cm. The contralateral pre-expanded thoracic random flap with the same area as that of the above-mentioned perforator flap was extended to repair the secondary defect with area of 8 cm×6 cm-17 cm×14 cm formed after transfer of the above-mentioned perforator flap. The exploration of perforating branch of transverse cervical artery, flap transfer and survival, injury repair, and complications were observed. The appearance and related function of donor and recipient sites and satisfaction of patients were followed up.Results:The perforating branches of transverse cervical artery appeared stably in the 10 patients. All the flaps were transferred to the recipient area without tension and survived. Both facial and cervical injuries were repaired successfully with no common complications. During the follow-up of 6 months-8 years, the color and texture of the pre-expanded anterior perforator flap of transverse cervical artery matched with the surrounding tissue, the functions of head raising and neck rotation of patients were significantly improved compared with those before operation, the color and texture of the flap transplanted in the first donor site matched with the original skin, linear scar left at the surgical incision, and 9 patients were satisfied with the restoration of the appearance and function of donor and recipient sites.Conclusions:The color and texture of the pre-expanded anterior perforator flap of transverse cervical artery match well with the face and neck, and the repairable area is large. After the perforator flap is removed, the secondary wound can be repaired with the pre-expanded thoracic random flap at the same time, and the injury of the chest donor site is alleviated. This relay repair method is a good choice for reconstructing extensive facial and cervical scar.

Objective:To explore effects of multidisciplinary collaborative continuous care based on WeChat platform on peri-implant tissue of patients with periodontitis.Methods:Stratified sampling was used to select 100 patients with chronic periodontitis who underwent periodontal treatment in Stomatology Center of Shenzhen People's Hospital from March 2019 to March 2020, and their periodontal status was stable and implant restoration was completed. According to admission time, they were divided into the observation group (50 cases, 82 implants) and the control group (50 cases, 78 implants) . The observation group was given continuous care mode of multidisciplinary cooperation based on WeChat platform, while the control group was carried out the conventional continuous care intervention. At 0, 3, 9 and 12 months after completion of implant restoration, the peri-implant index of patients in the two groups were evaluated, including plaque index, periodontal pocket depth and probing bleeding index.Results:Within 12 months after implant restoration, the plaque index of the observation group showed a decreasing trend, while that of the control group showed an increasing trend. At 6 and 12 months after repair, the plaque index of the observation group were lower than that of the control group, and the differences were statistically significant ( P<0.05) . Within 12 months of completion of implant restoration, the depth of periodontal pockets in both groups showed an increasing trend. At 3, 6, and 12 months after the restoration, the depth of periodontal pocket in the observation group were lower than that in the control group, and the differences were statistically significant ( P<0.05) . At 12 months after implant restoration, the exploratory bleeding index of the observation group and the control group was respectively 10.22 (0, 19.98) % and 34.23 (16.12, 43.23) %, and the difference between the two groups was statistically significant ( P<0.05) . Conclusions:Multidisciplinary collaborative continuous care based on the WeChat platform can effectively control various periodontal indexes of implants in patients with chronic periodontitis, maintain the health of periodontal tissues and help prevent the occurrence of peri-implantitis.

Objective:To analyze the clinical features, genetic characteristics, treatment and follow-up results of patients with hydrocephalus caused by methylmalonic acidemia combined with homocysteinuria, and to discuss the optimal strategies for assessing and treating such patients.Methods:From January 1998 to December 2020, 76 patients with hydrocephalus due to methylmalonic acidemia combined with homocysteinuria in the Department of Pediatrics in 11 hospitals including Peking University First Hospital were diagnosed by biochemical, genetic analysis and brain imaging examination. The patients were divided into operation-group and non-operation-group according to whether they underwent ventriculoperitoneal shunt. The clinical features, laboratory examinations, genotype, and follow-up data were retrospectively analyzed. Data were compared between the two groups using rank sum test, and categorical data were compared using χ 2 test. Results:Among the 76 patients (51 male, 25 female), 5 were detected by newborn screening, while 71 were diagnosed after clinical onset, 68 cases (96%) had early-onset, 3 cases (4%) had late-onset. The most common clinical manifestations of 74 cases with complete data were psychomotor retardation in 74 cases (100%), visual impairment in 74 cases (100%), epilepsy in 44 cases (59%), anemia in 31 cases (42%), hypotonia or hypertonia in 21 cases (28%), feeding difficulties in 19 cases (26%) and disturbance of consciousness in 17 cases (23%). Genetic analysis was performed in 76 cases, all of whom had MMACHC gene variations, including 30 homozygous variations of MMACHC c.609G>A. The most common variations were c.609G>A (94, 62.7%), followed by c.658_660del (18, 12.0%), c.567dupT (9, 6.0%) and c.217C>T (8, 5.3%). Therapy including cobalamin intramuscular injection, L-carnitine and betaine were initiated immediately after diagnosis. A ventriculoperitoneal shunt operation was performed in 41 cases (operation group), and 31 patients improved after metabolic intervention (non-operation group). There was no significant difference in the age of onset, the age of diagnosis, the blood total homocysteine, methionine, and urinary methylmalonic acid concentration between the two groups (all P>0.05). The symptoms of psychomotor development, epilepsy, and visual impairments improved gradually after a long-term follow-up in the operation group. Conclusions:Hydrocephalus is a severe complication of methylmalonic acidemia combined with homocysteinuria. The most common clinical manifestations are psychomotor retardation, visual impairment, and epilepsy. It usually occurs in early-onset patients. Early diagnosis and etiological treatment are very important. Hydrocephalus may improve after metabolic intervention in some patients. For patients with severe ventricular dilatation, prompt surgical intervention can improve the prognosis.
