Objective:To summarize the clinical characteristics and the features of electroencephalograph (EEG) of children with DEPDC5 gene variants related epilepsy.Methods:The clinical data, gene variation, EEG and head magnetic resonance image (MRI) of 20 epileptic children with DEPDC5 gene variants admitted to Department of Pediatrics, Peking University First Hospital from May 2017 to November 2020 were retrospectively analyzed.Results:Twenty patients with heterozygous DEPDC5 gene variants were enrolled, 8 of 20 patients were nonsense variants, 6 were missense variants, 3 were frame-shift variants, 2 were splicing variants, and 1 was large fragment deletion. Sixteen cases had hereditary variation and 4 had de novo variation. Fifteen of variations were novel. Nine were male, while 11 were female. Their latest follow-up age ranged from 10 months to 13 years and one month.The epilepsy onset age ranged from 3 hours to 11 years and 3 months, the median age was 10.5 months. Twelve (60%) patients had developmental delay. Nineteen patients had focal seizures, 7 had epileptic spasms, 1 had multiple seizure types including tonic, atypical absence, dystonic and myoclonic seizures. Epileptic form discharges were observed in 18 patients during the interictal phase, and 11 were focal discharges, 7 were multifocal discharges. Ten (50%) patients had abnormal brain MRI, including focal cortical dysplasia in 5 patients, undefined malformation of cortical development in 4 patients, hemimegalencephaly in 1 patient. Four patients were diagnosed as West syndrome and one patient was diagnosed as Lennox-Gastaut syndrome. Fourteen (70%) patients were diagnosed as drug-resistant epilepsy. Four patients became seizure-free by treatment with anti-epileptic drugs. Three children were treated with surgery, and 2 of them became seizure-free, 1 had more than 75% reduction in seizures.Conclusions:DEPDC5 gene variant epilepsy is inherited with incomplete penetrance and focal seizure is the major seizure type. However, epileptic spasms, generalized seizures can also be observed. Half of the patients brain malformations. Most of the patients are drug-resistant epilepsy. Patients with clear epileptogenic zones can be treated with surgery. Treatment-resistant patients are more likely to be complicated with developmental delay.

Many factors contribute to a successful total knee arthroplasty, and postoperative coronal lower limb alignment has always been a focus of joint surgeons. Previous researches have suggested that neutral alignment can bring higher prosthesis survival rate and better knee function. However, the theory has been challenged in recent years.In this article, the author introduces the axis, alignment and osteotomy of total knee arthroplasty briefly and reviews the studies on the neutral alignment and kinematic alignment of recent years in order to provide some advice for the clinical operation.

Objective To investigate the effect of quadratus lumborum block on postoperative analgesia and T lympho-cyte subsets in patients receiving transabdominal radical resection of rectal cancer, so as to provide clinical references. Methods From May 2016 to November 2017, 30 patients receiving selective radical resection of rectal cancer in our hospital were selected. The random number table was used to divide the patients into quadratus lumborum block group(experimental group) and incision partial infiltration block group (control group), with 15 patients in each group. After induction of general anesthesia, the experimental group underwent ultrasound-guided bilateral anterior lateral quadratus lumborum block. Each side was injected with 0. 375％ ropivacaine of 20 mL. The control group was induced by general anesthesia and 0. 375％ ropivacaine of 40 mL was injected for local infiltration block. The surgery time, volume of blood loss, total infusion volume of propofol, effective analgesia time, the amount of sufentanil infusion every 12 hours after surgery and resting VAS scores at postoperative different time points (2, 6, 12, 24, 36, 48 hours postoperatively) were observed and recorded. Venous blood (1 mL) was drawn 30 minutes before anesthesia(TO), 2 hours after surgery(T1), 1 day after surgery(T2) and 3 days after surgery(T3). T lymphocyte subsets were detected by flow cytometry(CD3+, CD4+, CD8+, CD4+/CD8+). Results Compared with the control group, the dosage of propofol in the experimental group was significantly less than that in the control group (P＜0. 05); the effective analgesia time in the experimental group was significantly longer than that in the control group (P＜0. 0l); the amount of sufentanil in the experimental group was significantly less than that in the control group at 0-12 h and 12-24 h after surgery (P＜0. 05); the resting VAS scores in the experimental group at 6 h and 12 h after the surgery were significantly lower than those in the control group (P＜0. 05); the levels of CD3+, CD4+, CD4+/CD8+ in the experimental group were significantly higher than those in control group at T2 (P＜0. 05). Compared with TO, CD3+, CD4+, CD4+/CD8+ at T1 and T2 in the two groups were significantly lower than those at TO(P＜0. 05); at T2, CD8+ in the control group was significantly lower than that at TO(P＜0. 05). Conclusion Bilateral quadratus lumborum block can significantly improve postoperative analgesia effect in patients receiving radical resection of rectal cancer and reduce the inhibition of T lymphocytes by surgical stress.

Objective To explore the effects of prospective rewarming nursing on spontaneous hypothermia in traumatic patients in emergency service. Methods Totally 67 traumatic patients admitted in the Emergency Department of Armed Police Zhejiang Corps Jiaxing Hospital between January and August 2016 were selected as the control group, and another 72 traumatic patients admitted between January and August 2017 were selected as the observation group by purposive sampling. Patients in the control group received conventional emergency treatment, while patients in the observation group received prospective rewarming nursing care on this basis. Body temperature and the incidence of shivering, arrhythmia and spontaneous hypothermia were compared between the two groups. Results The body temperature of the observation group stood at (36.38±0.21)℃ and (36.72±0.38)℃ respectively at admission and 1 hour post admission, both higher than that of the control group (t=24.241, 18.039; P＜0.01). The incidence rate of shivering in the observation group was 15.94% and 17.39% respectively at admission and 1 hour post admission, both lower than that of the control group (χ2=19.326, 19.141; P＜0.01). The incidence rate of arrhythmia in the observation group was 30.43%, while that of the control group was 49.15% (χ2=4.681, P=0.030). Conclusions Prospective rewarming can reduce the risks of spontaneous hypothermia in traumatic patients in emergency service.

BACKGROUND:Fast track surgery, also cal ed enhanced recovery after surgery, is a series of optimal measures adopted during the perioperative period on the basis of evidence-based medicine, to reduce the physical and mental trauma brought to the patient and accelerate their recovery. It has become the research focus of orthopedic clinic as the surgery and anesthesia skil s are improved a lot in recent years, especial y the articular surgery, which has been widely used in clinics. OBJECTIVE:To summarize the clinical study of the application of optimal measures in joint replacement surgery both at home and abroad in recent years. METHODS:The first author searched related articles in PubMed and Chinese Journal Ful-text Database from January 1997 to September 2016. The key words were“joint replacement, enhanced recovery after surgery, multi-mode analgesia, diet management, steroid hormones”. 81 articles were found at last and one monograph was included. RESULTS AND CONCLUSION:(1) We found that the recovery plan reduced the hospital stays of the patients from 4-12 days to 1-3 days, including pre-operative health education, shortening fasting and water-depriving duration before surgery, super-anesthesia before surgery and do not place catheter;adopting general anesthesia and appropriate adductor canal to relieve the pain, and stopping bleeding using tranexamic acid during operation;multi-mode analgesia, faster function exercise after anesthesia recovery, and drinking water in early phase after surgery during the perioperative period of joint replacement surgery conducted by the cooperation of surgeon, anesthetist, nurse and nutritionist. There were no significant improvements of postoperative complications rate and rehospitalization rate. (2) The research found that, enhanced recovery after surgery is suitable for most of the patients receiving joint replacement surgery, including those in advanced age, combined heart and lung disease before surgery, type 2 diabetes and smoking and drinking before surgery.

Objective To predict the value of advanced glycation end products (AGEs) in the risk and severity of coronary heart disease in diabetic patients.Methods Totally 120 cases were divided into 3 groups.Group A had no diabetes mellitus (DM) and no coronary atherosclerotic heart disease (CAD).Group B had DM without CAD.Group C had DM with CAD.The levels of AGEs,low density lipoprotein cholesterol (LDL-C),glycosylated hemoglobin,and the severity of coronary stenosis were detected.Receiver operating characteristic (ROC) curve was used to evaluate the sensitivities and specificities of AGEs for the diagnosis of DM with CAD.Results The highest level of AGEs,LDL-C,glycosylated hemoglobin and carotid plaque was in the C group,with a statistically significant difference (P ＜ 0.05).The severity of AGEs was significantly correlated with the severity of CAD and the Gensini score of AGEs (r =0.445).ROC curve showed that the sensitivity,specificity and area under ROC curve of AGEs determination of DM with CAD were 80.0％,75.0％,and 0.86,respectivity.Conclusions The level of AGEs is significantly correlated with atherosclerosis and prognosis in DM.The severity of CAD was higher in the patients with higher AGEs,and the incidence and severity of restenosis increased.

Objective To study the median effective doses (ED50) of dexmedetomidine to induce adequate sedation in elderly patients undergoing epidural anaesthesia. Methods Seventy-five elderly patients undergoing lower extremity operation under epidural anesthesia were selected, and the patients were divided into 5 groups according to the random digits table method with 15 cases each: D1 group (dexmedetomidine 0.2 μg/kg), D2 group (dexmedetomidine 0.4 μg/kg), D3 group (dexmedetomidine 0.6 μg/kg), D4 group (dexmedetomidine 0.8μg/kg) and D5 group (dexmedetomidine 1.0μg/kg). After 20 min of dexmedetomidine injection, adequate sedation was defines as observer′s assessment of alertness/sedation score (OAA/S score) ≤ 3 scores. The ED50 and 95% effective dose (ED95) of dexmedetomidine and 95% CI in elderly patients undergoing epidural anaesthesia were calculated by probit regression method. The changes of mean arterial pressure (MAP), heart rate, pulse oxygen saturation (SpO2) and OAA/S score among 5 groups were compared. The incidences of adverse effects such as hypotension, bradycardia, hypoxemia and excessive sedation were compared. Results The ED50 in elderly patients was 0.36 μg/kg (95% CI 0.27 - 0.44 μg/kg); the ED95 was 0.94 μg/kg (95% CI 0.71 - 1.62 μg/kg). After dexmedetomidine injection, the MBP, heart rate, SpO2 and OAA/S scores in 5 groups were decreased, but in the D4 group and D5 group the decreases were more significant. The incidences of hypotension, bradycardia and excessive sedation in D1 group, D2 group and D3 group were significantly lower than those in D4 group and D5 group:2/15, 5/15 and 8/15 vs. 14/15 and 15/15;1/15, 6/15, 7/15 vs. 13/15 and 14/15;0, 0 and 1/15 vs. 5/15 and 7/15, the incidences of hypoxemia in D1 group, D2 group and D3 group were significantly lower than those in D5 group: 0, 0 and 0 vs. 3/15 and 4/15, and there were statistical differences (P<0.05). There were no statistical differences in incidences of adverse effects between D4 group and D5 group (P>0.05). Conclusions The ED50 of dexmedetomidine in elderly patients undergoing epidural anaesthesia is 0.36μg/kg, (CI 0.27-0.44μg/kg). The incidences of adverse effects are increased when single-dose dexmedetomidine is more than 0.8μg/kg.

OBJECTIVETo investigate the distribution and proportion of subtypes of pol gene in HIV-1 epidemic strains in Guangxi Autonomous Region.

METHODS152 HIV-1 patients were enrolled from 11 cities in Guangxi Autonomous Region from 2010 to 2012 by convenient sampling. Inclusion criterias were listed as the fdlowing: HIV-1 infection was confirmed by Western blot, HIV-1 viral load >1 000 copies/ml, > 18 year-old, and without any serious illnesses. 5 ml of peripheral blood samples were obtained from each patient. The viral RNA was isolated from plasma and used for amplification of full-length pol gene by nested RT-PCR. The amplified products were sequenced. After editing and modification, all sequences were characterized for preliminary subtyping by genotyping and confirmed with phylogenetic tree constructed by MEGA 5.03 software. The recombinant identification of 2 unknown recombinant strains was determined by RIP and jpHMM at GOBICS.

RESULTSAmong 152 patients, 137 full-length pol genes were successfully amplified and 127 HIV-1 subtypes were identified. The distribution and proportion of subtypes was summarized as the following 71 cases of CRF01_AE, accounting for 55.9% (71/127), 38 CRF08_BC, 29.9% (38/127), 13 CRF07_BC, 10.2% (13/127), and 3 B (B'), 2.4% (3/127), 2 unknown recombinant strains, 1.6% (2/127). In 11 cites of Guangxi Autonomous Region, subtype CRF01_AE was the dominant strain. Among heterosexual transmitted patients and drug abusers, the proportions of subtype CRF01_AE were 67.4% (58/86) and 34.1% (14/41), respectively. There was a significance different in the distribution of CRF01_AE in different routes of transmission (χ(2)=15.07, P<0.001). In age 21- 35, age 36- 60 and age>60 groups, the proportions of CRF01_AE was 43.6% (17/39), 57.6% (38/66), 77.3% (17/22), and CRF08_BC was 43.6% (17/39), 28.8% (19/66), 9.1% (2/22), respectively, the difference in proportions was significant(χ(2)=8.48, P= 0.014). The patterns of two unknown recombinant strains were found to be CRF01_AE/B (B') and CRF01_AE/C/B(B'), respectively.

CONCLUSIONCRF01_AE was the dominant HIV-1 subtype in Guangxi Autonomous Region from 2010 to 2012, with heterosexual transmission as its main spreading route. The two unknown recombinant strains in Guangxi Autonomous Region were reconstructed by subtype CRF01_AE and CRF_BC.
