Purpose To evaluate the correlations between high resolution CT (HRCT) findings and IASLC/ATS/ERS pathological classification of ground glass nodule (GGN). Materials and Methods 121 patients with confirmed GGN were selected, and divided into benign group (22 cases), PIL group (21 cases), microinvasive carcinoma group (26 cases) and invasive carcinoma group (52 cases), then the imaging, pathology and prognosis data of patients with pulmonary GGN were reviewed, and the differences among GGN of different pathological types were analyzed.Results Maximum diameter, margin, vacuole sign, solid component, shape and blood vessels through of GGN were significantly different among the four groups (χ2=9.945-31.068,P<0.05). Maximum diameter and margin were significantly different between invasive adenocarcinoma and other groups (P<0.008); vacuole sign of the benign group was significantly different with other groups (P<0.008); the existence of solid component and shape were significantly different between invasive adenocarcinoma and minimally invasive adenocarcinoma (P<0.008); there was significant difference of blood vessels through between invasive adenocarcinoma and benign lesions (P<0.008). Among the 121 lesions, no metastasis except one invasive adenocarcinoma case complicated with distant metastasis.Conclusion Maximum diameter of GGN greater than 16.35 mm, with spiculation or lobulation represent invasive adenocarcinoma; vacuole sign within the GGN represent malignancy; with solid component and irregular shape can be used to identify invasive adenocarcinoma from minimally invasive adenocarcinoma; while blood vessels through can be used to identify invasive adenocarcinoma from benign lesions; the prognosis of GGNs is well with only 0.83% probability of distant metastasis.

Objective To review the nomenclature and terminology, diagnostic criteria, classification and evaluation of intellectual disability using WHO ICD-11 and ICF.Methods The theories and approaches of ICD-11 and ICF were adopted to analyze the nomenclature and terminology, diagnostic criteria, classification and evaluation of intellectual disability.Results ICD-11 and ICF had established the nomenclature and terminology, diagnostic criteria, classification and evaluation of intellectual disability from the perspectives of content model of ICD-11 and functioning of ICF respectively. Intellectual disability had used nomenclature of disorder of intellectual development and one of sub-categories of mental, behavioral or neurodevelopmental disorders. Intellectual disability was also defined as both impairment of intellectual function (b117) and functional limitation of adaptive behaviors (d1-d9) using ICF. Occurrence age of intellectual disability was before 18 years old for diagnostic criteria of ICD-11 and ICF.Conclusion The nomenclature and terminology, diagnostic criteria and classifications of intellectual disability have been reviewed and updated using the theories and approaches of ICD-11 and ICF. It provides theoretical supports, approaches, and standardized tools for the development of rehabilitation service for people with intellectual disability.

Objective To analyze the unmet needs of services and support, and design structured, standardrized and individualized service and support plans for people with intellectual disability using ICF framework.Methods In respective of intellectual function and adaptive behavior, a structured, standardrized and individualized service and support plan had been constructed according to process of individualized plan using ICF.Results Based on ICF model of functioning and disability, the structured and standardized service and support plan had been constructed, including functional diagnosis and service needs reporting, and individualized services protocols.Conclusion With the analysis of functioning and reporting of unmet needs of service using ICF, the structured, standardrised and individualized service and support plan can be developed to promote the total rehabilitation for people with intellectual disabilities.

Objective To establish the theoretical framework and approaches of services provision of vocational rehabilitation (VR) for people with intellectual disability (ID) to promote the decent employment of people with ID.Methods The employment difficulties of people with ID had been analyzed using ICF, and the content and the procedure of VR for people with ID had been explored.Results According to ICF, the employment difficulties of people with ID included functioning, barriers of employment and environmental factors. VR services for people with ID included assessment of employment barriers and vocational capacity, vocational counseling, vocational skill development and training, vocational guidance, support and assistance service, VR and politics development and research. The procedures of VR services for people with ID included assessing employment difficulties and vocational abilities, establishing employment setting and target, planning and implementing individualized VR program, and follow-up services.Conclusion It is necessary to use ICF to develop structured and individualized VR framework and approaches of VR for people with ID.

Objective To study the effect of different nursing methods in double plasma exchange treatment on multiple myeloma. Methods 30 patients with multiple myeloma were randomly assigned to the experimental group (EG) and the control group (CG), 15 patients in each group. In the CG, the canal was washed by the priming fluids according to the machine requirements; patients were given the LMWHC at the beginning of the treatment. During the treatment, the canal was washed discontinuously by normal saline (NS).An improved priming method was adopted in the EG: the canal was washed with NS included heparin, patients were given the LMWHC. After 20 - 30 mins, the treatment started. Squeeze the artery pot discontinuously during the treatment; compare the clotting situation and treatment parameters of two groups. Results Level Ⅱ - Ⅲ clotting incidence rate of EG was 23.3% and of CG was75.0%. The difference between two groups was statistically significant (X2 =37.95,P ＜0. 05); TMP of CG were higher than those of EG[(17.32 ±5. 22)mm Hg vs (4.73 ± 3.27) mm Hg, t = 9. 76, P ＜ 0. 05]; total NS amount used, replacement plasma, waste plasma and treatment time of CG were lower than EG (P ＜ 0. 05). Conclusions Compared with CG, the priming methods, anticoagulation solutions and washing methods of EG have better control on the occurrence of clotting and require less amount of washing NS to reduce the burden on kidney without influencing the effect of the treatment.

Perioperative stroke is cerebral infarction occurring in the perioperative period.The incidence of perioperative stroke in non-cardiac,and non-neurologic surgery is about 0.7％,but the mortality can be as high as 26％ to 40％.The outcome of the patients with perioperative stroke can be disastrous.Here we report a case of perioperative ischemic stroke that occurred after surgery of lumbar decompression and pedical screw fixation.A 76-year-old female admitted to our hospital because of lumbar spinal stenosis.Her medical history included hypertension and diabetes for ten years.Her personal history included a smoking history of 60 years by 2 cigarettes per day,not quitting.Her carotid artery ultrasound showed multiple low echo plaques on the right side and multiple high echo plaques on the left side of the carotid artery,but without distinct stenosis.Other examinations and tests showed no distinct abnormality.She went on a lumbar decompression and pedical screw fixation uneventfully.The blood loss was 400 mL and autologous blood transfusion 150 mL.The arterial blood pressure (ABP) maintained during 100-130 mmHg/60-80 mmHg (1 mmHg =0.133 kPa).Sixty minutes after she recovered from general anesthesia,the patient developed symptoms of slurred speech and right limbs weakness.The anesthesiologist evaluated the patient immediately with National Institute of Health Stroke Scale (NIHSS).The NIHSS score was 11 and a stroke was highly suspected.The acute stroke team was therefore initiated and fast responded.Within 4 h,digital subtraction angiography (DSA) was proceeded,which showed the M1 segment of the left middle cerebral artery was occluded and the local stenosis of her right middle cerebral artery was up to 80％.After the successful embolectomy by Solitaire stent,the left middle cerebral artery reflowed and the forward blood flow was thrombolysis in myocardial infarction (TIMI) grade 3.The patient was discharged after 33 days after the surgery with a NIHSS of 9.Our case provides an example that an acute stroke team that included the department of anesthesiology can be beneficial to the patients' perioperative strokes.During the perioperative period,anesthesiologists should be included into the acute stroke team,because anesthesiologists and anesthesia nurses might be first observers of those early onset strokes.Our case also put forward this thought that a standard peri-operative stroke evaluation tool,like NIHSS,should be discussed and applied to facilitate and accelerate the initiation of perioperative acute stroke team.

Objective To investigate the characteristics about the prevalence of thyroid nodules detected on color Doppler uhrasonography(US) in people residing in Dalian City who undergo regular physical examinations, as well as its relative factors. Methods All thyroid sonographic and questionair procedures were performed in the 6020 people above 18-year-old living in the four districts of Dalian City for at least 5 years, who were examined at the department of health medical center of Dalian Municipal Central Hospital from May 2006 to March 2007. Urinary iodine concentration was measured in 2039 healthy adults selected by age layers in our study population. Moreover, urinary iodine concentrations were determined in 220 children aged 8-10 years old who were randomly chosen from four communities (55 children per elementary school from each community). The analysis of logistic regression was conducted for the risk factors linked to thyroid nodules. Results The prevalence of thyroid nodules in the 6020 adults was 38.5%(2319/6020), in which nodules sized between 0.3 and up to 0.5 cm were found in 17.1% (1030/6020), and those above 0.5 cm in 21.4% (1289/6020). Ultrsonography revealed solitary nodules in 17.2% (1036/6020), multinodular goiter in 21.3% (1283/6020). Fifty-four point nine percent (1272/2319) thyroid nodules showed solid internal echographic structures, 30.2%(701/2319) mixed and 14.9%(346/2319). The thyroid nodule detected rate in female individuals was 46.1% (1102/2393), among whom multinodular goiter [59.1% (651/1102)] was more than solitary nodules[40.9(451/1102)] in female; while only 33.6%(1217/3627) of male were detected to have thyroid nodule, there was a difference between the genders (χ2=95,079,P<0.01). The mediam urinary iodine concentration(MUI) was 184.32 μg/L in children and 216.75 μg/L in the health adults, moreover, it was 216.55 μg/L and 217.00 μg/L in the people with thyroid nodules and those without nodules without a significant difference (P>0.05). The rate of thyroid nodules gradually increased with age(χ2=344.998, P<0.01). The occurance of thyroid nodules was significant associated with gender and age(P<0.01). Conclusions The nutritional iodine intake in the four communities of Dalian City are adequate. The prevalence of thyroid incidentalomas is relatively high in this group of people receiving medical examination.

Objective:To investigate the effect of neoadjuvant chemotherapy on the safety of laparoscopic D 2 radical resection and prognosis of patients with locally advanced gastric cancer. Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 351 patients with locally advanced gastric cancer who underwent laparos-copic D 2 radical resection in the Second Affiliated Hospital of Air Force Medical University from December 2016 to December 2021 were collected. There were 256 males and 95 females, aged (58±9)years. Of the 351 patients, 124 cases undergoing neoadjuvant chemotherapy were divided into the neoadjuvant chemotherapy group, 227 patients undergoing postoperative adjuvant chemotherapy were divided into the adjuvant chemotherapy group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) effect evaluation of neoadjuvant chemotherapy; (3) intraoperative and postoperative situations; (4) postoperative histopathological examinations; (5) follow-up. Propensity score matching was done by the 1∶1 nearest neighbor matching method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measure-ment data with skewed distribution were represented as M(range) or M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to draw survival curves, and the Log-Rank test was used for survival analysis. Results:(1) Propensity score matching conditions and comparison of general data of patients between the two groups of patients after matching. Of 351 patients, 154 cases were successfully matched, including 77 cases in the neoadjuvant chemotherapy group and 77 cases in the adjuvant chemotherapy group. The elimination of gender, age, preoperative body mass index, clinical T staging and clinical N staging confounding bias ensured comparability between the two groups after propensity score matching. (2) Effect evaluation of neoadjuvant chemotherapy. Of the 77 patients receiving neoadjuvant chemotherapy, none of patient achieved complete response, 26 patients achieved partial response, 46 patients showed stable disease, 5 patients had progression of disease, showing the objective response rate as 33.8%(26/77) and the disease control rate as 93.5%(72/77). There were 15 males and 11 females sensitive to neoadjuvant chemotherapy, while 46 males and 5 females not sensitive, showing a significant difference between them ( χ2=11.05, P<0.05). (3) Intra-operative and postoperative situations. The operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion, time to postoperative first flatus, time to postoperative first liquid food intake, duration of postoperative hospital stay, cases with postoperative immediate complications, cost of hospital stay were (308±71)minutes, 100(range, 20?600)mL, 5, 3.0(range, 2.0?10.0)days, 4.0(range, 2.0?12.0)days, 9.0(range, 4.0?31.0)days, 7, 7.96(7.37,8.58) ten thousand yuan in patients of the neoadjuvant chemotherapy group, versus (296±67)minutes, 100(range, 20?500)mL, 4, 3.5(range, 1.0?14.0)days, 4.0(range, 2.0?15.0)days, 8.0(range, 5.0?45.0)days, 11, 8.18(7.52,9.19) ten thousand yuan in patients of the adjuvant chemotherapy group, showing no signifi-cant difference in the above indicators between the two groups ( t=1.13, Z=?0.37, χ2=0.12, Z=?1.26, ?0.33, ?0.70, χ2=1.01, Z=?1.04, P>0.05). (4) Postoperative histopathological examinations. Results of postoperative histopatho-logical examinations showed that all 154 patients achieving R 0 resection. Cases with pathological T staging as stage T1, stage T2, stage T3, stage T4, cases with pathological N staging as stage N0, stage N1, stage N2, stage N3, number of positive lymph nodes, cases with human epidermal growth factor receptor 2 (negative, positive) were 3, 7, 5, 62, 27, 19, 19, 12, 1(range, 0?28), 59, 18 in patients of the neoadjuvant chemotherapy group, versus 0, 0, 2, 75, 17, 15, 21, 24, 3(range, 0?31), 44, 33 in patients of the adjuvant chemotherapy group, showing significant differences in the above indicators between the two groups ( Z=?3.39, ?2.55, ?3.12, χ2=6.60, P<0.05). (5) Follow-up. Of the 154 patients, 143 patients were followed up for 37(range, 5?69)months. The 3-year overall survival rate and 3-year disease-free survival rate was 72.1% and 70.0%, respectively, in patients of the neoadjuvant chemotherapy group, versus 74.8% and 76.6% in patients of the adjuvant chemo-therapy group, showing no significant difference in the above indicators between the two groups ( χ2=0.14, 0.60, P>0.05). Conclusions:Compared to postoperative adjuvant chemotherapy, neoadjuvant chemotherapy does not bring additional surgical risks, but can reduce the tumor stage of patients who underwent laparoscopic D 2 radical resection for locally advanced gastric cancer. However, it does not show any advantage in improving survival of patients.

BACKGROUNDXS0601, consisting of active ingredients (Chuangxiongol and paeoniflorin), has been shown to inhibit arterial neointimal hyperplasia in animal models and in preliminary human studies. The objective of this study was to evaluate the safety and efficacy of XS0601 in preventing restenosis following percutaneous coronary intervention (PCI).

METHODSA multi-center, randomized, double-blind, placebo-controlled trial was conducted. A total of 335 patients were randomized into treatment with the oral administration of XS0601, or a placebo for 6 months after successful PCI. Angiographic follow-up was scheduled at 6 months, and clinical follow-ups performed at 1, 3 and 6 months after PCI. The primary end point was angiographic restenosis. The secondary end points were the combined incidence of death, target lesion nonfatal myocardial infarction, repeat angioplasty, and coronary artery bypass graft surgery.

RESULTSA total of 308 patients (91.9%) completed the study and 145 cases (47.1%) received angiographic follow-up. The restenosis rates were significantly reduced in the XS0601 group as compared with the placebo group (26.0% vs. 47.2%, P < 0.05), and the minimum lumen diameter (MLD) was greater [(2.08 +/- 0.89) mm for XS0601 vs. (1.73 +/- 0.94) mm for placebo, P < 0.05]. XS0601 also significantly reduced the combined incidence of major adverse cardiac event (10.4% in the XS0601 group vs. 22.7% in the placebo group, P < 0.05). The incidence of recurrent angina at 3 and 6 months after PCI was also significantly reduced in XS0601 group (7.1% and 11.0%) as compared with those in placebo group (19.5% and 42.9%) (P < 0.05). No significant side effects occurred within the 6-month follow-up period in the XS0601 group.

CONCLUSIONAdministration of XS0601 for 6 months is demonstrated to be safe and effective in reducing restenosis in post-PCI patients.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.
