Objective:To evaluate the clinical efficacy of a single-session implantation of spinal cord electrical stimulation with neurophysiological monitoring a spinal cord electrical stimulator under general anesthesia with neurophysiological monitoring for the treatment of high-risk diabetic foot.Methods:The clinical data of seven patients with high-risk diabetic foot who underwent spinal cord electrical stimulation in neurosurgery ward nine of Tianjin Huanhu Hospital from May 2022 to May 2023 were collected. The operation was performed under general anesthesia with the "C" arm X ray machine guidance and neurophysiological monitoring. The arterial diameter and peak flow rate of lower extremity, lower extremity skin temperature (calf skin temperature, foot skin temperature), visual analog scale (VAS), continuous distance of movement, blood glucose level and toe wound were compared between patients before and after surgery.Results:A total of seven patients with high-risk diabetic foot were included. The diameters and peak flow rates of femoral artery, popliteal artery, anterior tibial artery, posterior tibial artery and dorsal foot artery in both lower limbs were significantly improved after surgery. All patients had different degrees of lower limb pain before operation. After operation, VAS score decreased significantly (1.1±0.9 vs. 6.8±3.4), the pain was significantly relieved, and the calf skin temperature and foot skin temperature were significantly higher than those before surgery [calf skin temperature (℃): 33.3±0.9 vs. 30.9±0.7, foot skin temperature (℃): 31.4±0.8 vs. 29.1±0.6], fasting blood glucose and postprandial blood glucose were significantly lower than those before surgery [fasting blood glucose (mmol/L): 7.6±1.4 vs. 10.5±1.2, postprandial blood glucose (mmol/L): 9.3±2.3 vs. 13.5±1.1], the differences were statistically significant (all P < 0.01). The lower limb movement of all seven patients was significantly improved after surgery, including one patient who needed wheelchair travel before surgery, and one patient who had intermittent claudication before surgery. Among them, one patient needed wheelchair travel and one patient had intermittent claudication before surgery. All patients could walk normally at 2 weeks after operation. Among the seven patients, two patients had the diabetic foot wound ulceration before surgery, which could not heal for a long time. One month after surgery, blood flow around the foot wound recovered and the healing was accelerated. The wound was dry and crusted around the wound, and the wound healed well. Conclusion:For diabetic high-risk foot patients who are intolerant to diabetic peripheral neuralgia and local anesthesia spinal cord electrical stimulation test, one-time implantation of spinal cord electrical stimulator under general anesthesia under neurophysiological monitoring can effectively alleviate peripheral neuralgia and other diabetic foot related symptoms, improve lower limb blood supply, and reduce the risk of toe amputation. Clinical practice has proved the effectiveness of this technique, especially for the early treatment of diabetic high-risk foot patients.

Objective To discuss the effect of posterior quadrant disconnection surgery on temporoparietooccipital intractable epilepsy.Methods A retrospective review of clinical,neuropsychological,EEG,imaging and histopathological data of 3 patients with intractable epilepsy,admitted to and underwent posterior quadrant disconnection surgery in our hospital from February 2012 to October 2013,was performed.Results The clinical manifestations of 3 patients were simple partial seizures generalized seizures secondary to partial seizures and generalized tonic clonic seizures.MRI examination showed that 3 patients were porencephaly,white matter dysplasia,and gray matter heterotopia.Patients were treated with right posterior quadrant disconnection surgery after general anesthesia.Follow up of 32,12 and 29 months was respectively performed in these 3 patients.The seizure control result after surgery was Engel Ⅰ in 2 patients and Engel Ⅱ in one patient.There was no new prolonged neurological deficit or death.Conclusion Posterior quadrant disconnection surgery is an effective method for posterior quadrant intractable epilepsy,which results in similar excellent early seizure control as hemispherectomy.

Strain-resource engineering is often considered as an important infrastructure of microbiology related research and industry. The western developed countries took the lead in establishing the classical microbial resource utilization method, and continuously improved the preservation system, species annotation technology and global sharing mechanism, which realized the expansion and reserve of biological resources since end of the 19th century. The rich and diversified germplasm resources, standard strains and production strains not only have important economic values, but also maintain the advantages of scientific research, bioeconomy (such as antimicrobial agents, vaccines, detection reagent development and standard development, etc.) and national security. Although there has been a lot of progress in related research in recent years, compared with developed countries, there is still a big gap in related fields in China. The investment and top-level design in this area lag far behind the western developed countries, and it is not commensurate with the current level of economic and social development in my country. Drawing lessons from the practice of WFCC and WDCM (World Data Center for Microorganisms, Global microbial data Center, affiliated to WFCC), for the purpose of collecting new clinical species/strains, this paper puts forward some suggestions on the identification, preservation and upload system of isolates.

Objective:To investigate the value of stereo-electroencephalography (SEEG)-guided radiofrequency thermocoagulation (RFTC) in patients with focal epilepsy.Methods:Eighteen patients with focal epilepsy admitted to and treated by SEEG-guided RFTC in our hospital from April 2019 to December 2020 were chosen. The clinical data of these patients were retrospectively analyzed, and follow up was performed monthly by telephone and outpatient subsequent visit. The treatment efficacies of these patients were evaluated by Engel grading.Results:(1) The number of electrodes accurately implanted into the intended target in these 18 patients was 4-11 (6.56±2.15 on average); unilateral implantation was noted in 6 patients, and bilateral implantation was noted in 12 patients. SEEG monitoring showed that 7 patients were with frontal lobe epilepsy, 8 were with temporal lobe epilepsy, 2 were with frontotemporal junction epilepsy, and one was with temporal occipital junction epilepsy. (2) Two-9 RFTC electrodes (3.43±1.47 on average), and 9-42 RFTC contacts (17.38±9.20 on average) were given in these 18 patients. One patient developed seizures during the course of RFTC, one had temporary mental symptoms after RFTC, one had diffuse brain edema with intracranial hypertension, and one had asymptomatic regional brain edema. The total complication incidence was 22.2% (4/18) and no permanent neurological impairment occurred. (3) Eleven patients (61.1%) had recurred seizure within 1 year of RFTC: 3 (27.3%) recurred within 1 month, 3 (27.3%) recurred within 1-3 months, 3 (27.3%) recurred within 3-6 months, and 2 (18.2%) recurred within 6-12 months; however, the duration and frequency of seizure were obviously decreased as compared with those before RFTC. Seven patients (38.9%) received craniotomy after RFTC; follow up for 5-24 months showed that 12 patients were with Engel grading I, 4 were with Engel grading II, 2 were with Engel III, and no one was with Engel grading IV.Conclusions:SEEG-guided RFTC has enabled patients with focal epilepsy to achieve complete remission of their seizures with varying durations, and some patients have achieved long-term remission of their seizures. For patients with recurrent epilepsy after SEEG-guided RFTC, further craniotomy of the epileptogenic area is still effective.

Objective:To explore the distribution characteristics of pathogens in adult patients with community-acquired pneumonia (CAP) and to provide basis for the diagnosis, treatment, prevention of CAP.Methods:1 446 inpatients with CAP were prospectively enrolled in a third-class hospital in Beijing in recent 5 years (from January 2015 to December 2019). Respiratory tract samples were collected for smear, culture, nucleic acid, antigen and antibody detection to identify the pathogen of CAP. Mann-Whitney U test was used for continuous variables and χ 2 test or Fisher′s exact test was used for categorical data for statistical analysis. Results:Among the 1 446 patients, 822 (56.85%) patients were infected with a single pathogen, 231 (15.98%) patients were infected with multiple pathogens, and 393 (27.18%) patients were not clear about the pathogen. Influenza virus is the first pathogen of CAP (20.95%, 303/1 446), mainly H1N1 (8.51%, 123/1 446), followed by mycoplasma pneumoniae (7.19%, 104/1 446), Mycobacterium tuberculosis (5.33%, 77/1 446) and Streptococcus pneumoniae (5.05%, 73/1 446). The outbreak of H1N1 occurred from December 2018 to February 2019, and the epidemic of mycoplasma pneumoniae pneumonia was monitored from August to November 2019. Patients under 65 years old had high detection rates of Mycoplasma pneumoniae (14.41% vs. 2.41%, χ2=74.712, P<0.001), Streptococcus pneumoniae (8.16% vs. 2.99%, χ2=18.156, P<0.001), rhinovirus (6.08% vs. 3.56%, χ2=5.025, P<0.025), Chlamydia pneumoniae (5.90% vs. 1.15%, χ2=26.542, P<0.001) and adenovirus (3.13% vs. 0.92%, χ2=9.547, P=0.002). The severe disease rate of CAP was 14.66% (212/1 446), and the average mortality rate was 3.66% (53/1 446). The severe illness rate and mortality rate of bacterial-viral co-infection were 28.97% (31/107) and 19.63% (21/107), respectively. Conclusions:Influenza virus is the primary pathogen of adult CAP. Outbreaks of Mycoplasma pneumoniae and H1N1 were detected in 2018 and 2019, respectively. The remission rate and mortality rate of virus-bacteria co-infection were significantly higher than those of single pathogen infection. Accurate etiological basis not only plays a role in clinical diagnosis and treatment, but also provides important data support for prevention and early warning.
