Objective To investigate radiological features on computed tomography (CT) in the di agnosis of portal venous and intestinal wall gas in patients with ischemic bowel disease.Methods The clinic-pathological data of 17 patients with portal venous and intestinal gas associated with ischemic bowel diseases from Wenzhou People's Hospital (n =6),Yueqing People's Hospital (n =5),Shanghai Xuhui Dahua Hospital (n =3) and the Second Affiliated Hospital of Wenzhou Medical University (n =3) from January 2013 to October 2016 were analysed retrospectively.All the patients have been fasting for 8 h prior to CT scans.Enhanced CT study was performed following routine CT with no abdominal pressure for breath less scanting.Portal venous gas,intestinal wall gas,intestinal thickness and density,mesentery thickness,celiac effusion,and severity of intestinal wall enhancement were recorded.Results All the 17 patients ex perienced abdominal distension and pain.Additionally,nausea and vomiting was observed in 9 patients,di arrhea in 7,melena in 7,periumbilical tenderness in 11 and rebound tenderness in 8.CT scans of these 17 patients showed portal venous gas,including massiveprune-tree signs of hepatic vein and portal vein (n =11) and scanty gas shadows in distal hepatic vein (n =6).Intestinal gas sign was determined in all these patients (n =17),including single bubble shadow (n =8),multiple bubble shadow (n =7),and band-shaped bubble (n =2).Furthermore,CT study indicated extensive intestinal wall thickening with edema (n =13),predominate luminal extension of thinner bowels (n =4),scanty celiac effusion (n =3).Enhanced CT scans demonstrated 8 patients with decreased enhancement of intestinal wall and mesentery with diseases,target and halo signs observed in enhanced scans.Conclusions Portal venous and intestinal wall gas may demonstrate distinctive CT imaging.CT study could have superior sensitivity and spe cialty in clinical diagnoses of ischemic bowel diseases.

Under the guidance of meridian theory, the acupoints heat-sensitive moxibustion is a treatment method which applies moxa stick to perform mild moxibustion at heat-sensitive acupoints, which can arouse the meridian sensation transmission and promote the movement of meridian qi; consequently, the qi can be extended to the diseases. For its many advantages, such as no direct contact on skin, no injuries, no pains, fewer side effects, easy operating and moderate cost, the acupoints heat-sensitive moxibustion is widely accepted in dermatology, male urology disease, rectum and anus diseases and breast diseases. The application and research status of the acupoints heat-sensitive moxibustion in traditional Chinese surgery in recent years is reviewed, and several problems and suggestions in its clinical application and research are proposed, aiming to provide clinical basis for its further development and clinical application in traditional Chinese surgery.

Objective To examine the distribution of bacterial species and antimicrobial susceptibility profile of pathogens in febrile neutropenic patients.Methods A total of 355 bacterial strains were isolated from febrile neutropenic patients in Shanghai General Hospital from January 2005 to December 2012. Antimicrobial susceptibility testing was done by Kirby-Bauer method. The susceptibility testing results were analyzed according to CLSI 2014 breakpoints.Results Gram-negative bacteria accounted for 70.4% of the 355 isolates, while gram-positive organisms accounted for 29.6%. The most common bacterial species werePseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter baumannii, Escherichia coli, Stenotrophomonas maltophiliaand Staphylococcus haemolyticus. Non-fermentative bacteria accounted for 53.2% of all the gram-negative bacterial isolates. All theEnterococcus and
Staphylococcus isolates were susceptible to linezolid, vancomycin and teicoplanin. All theStaphylococcus strains were resistant to methicillin.P. aeruginosa isolates were relatively more susceptible to cefoperazone-sulbactam, piperacillin-tazobactam and cefepime (>70%) than imipenem (40.8%) and meropenem (59.2%). All theK. pneumoniae isolates were susceptible to imipenem and meropenem and more than 70% of the isolates were susceptible to cefoperazone-sulbactam, amikacin. More than 80% of theA. baumannii isolates were susceptible to carbapenems, cefoperazone-sulbactam, amikacin, ciprolfoxacin and aminoglycosides. All the E. coli isolates were susceptible to carbapenems and more than 70% were susceptible to cefoperazone-sulbactam and ceftazidime. More than 90% of theS. maltophilia strains were sensitive to levolfoxacin, minocycline, cefoperazone-sulbactam and trimethoprim-sulfamethoxazole.Conclusions Our data suggest that gram-negative bacteria, especiallyEnterobacteriaceae and non-fermentative bacteria, are still the primary pathogens in febrile neutropenic patients. Antimicrobial resistant strains are prevalent. Such data of bacterial species and antimicrobial susceptibility proifle of pathogens in febrile neutropenic patients are useful for empirical antimicrobial therapy of such infections.

OBJECTIVETo investigate the efficacy of allogeneic peripheral blood stem cell transplantation (PBSCT) in the treatment of severe aplastic anemia (SAA) and severe infection.

METHODSA patient with SAA and pseudomonas aeruginosa septicemia was treated with PBSCT from an HLA-identical sibling with cyclophosphamide (CY) and total body irradiation (TBI) for conditioning. The patient was infused with 20.3 x 10(8)/kg mononuclear cells including 61.0 x 10(6)/kg CD34(+) cells following the conditioning regimen.

RESULTSTwelve days after PBSCT, the absolute neutrophil count (ANC) of 1.0 x 10(9)/L was achieved, with platelet count > 50 x 10(9)/L at twenty days. The donor origin of engraftment was confirmed by polymerase chain reaction (PCR) analysis of short tandem repeats at the end of the first, sixth and twelfth month. The patient's body temperature dropped to normal level when her ANC reached 0.5 x 10(9)/L on day 10, and the bacterial culture of blood sample became negative subsequently. Symptoms and signs of acute or chronic graft versus host disease (GVHD) were not observed in 30 months after PBSCT.

CONCLUSIONSHematopoiesis was reconstituted shortly after PBSCT. The combination of CY and TBI and the infusion of sufficient peripheral blood stem cells may contribute to the successful engraftment. PBSCT may be considered as the first choice when hematopoietic stem cell transplantation is needed for SAA patients complicated with severe infection.

Objective:To investigate the application value of triangular modal construed for planning approach of laparoscopic local resection of liver tumors located in superior part of central liver lobe.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 10 patients who underwent local laparoscopic resection of liver tumors located in superior part of central liver lobe at the Affiliated Hospital of Qingdao University from January to June 2020 were collected. There were 6 males and 4 females, aged from 41 to 63 years, with a median age of 54 years. Preoperative triangular model was constructed for all patients to plan approach of laparoscopic local resection of liver tumors located in superior part of central liver lobe. Observation indicators: (1) preoperative general situations of patients; (2) surgical situations; (3) follow-up. Follow-up was conducted by outpatient examination or telephone interview to detect tumor recurrence and survival of patients up to February 2021. Measurement data with normal distribution were expressed as Mean± SD. Count data were expressed was absolute numbers. Results:(1) Preoperative general situations of patients: hepatocellular carcinoma was found in 7 cases, inthahepatic cholangiocarcinoma was found in 2 cases and ovarian cancer with liver metastasis was found in 1 case. Three cases had tumors located in S4a segment, 2 cases had tumors located in ventral subsegment of S8 segment, 2 cases had tumors located in dorsal subsegment of S8 segment, and 3 cases had tumors across the ventral segment of S4a+S8. The diameter of tumors was (3.4±1.0)cm. (2) Surgical situation: all the 10 patients underwent R 0 resection successfully, with no intraoperative blood transfusion or conversion to open surgery. The operation time of 10 patients was (149±59)minutes, the volume of intraoperative blood loss was (294±163)mL, the minimum surgical margin of specimen was (1.1±0.2)cm. The alanine aminotransferase was (324±151)U/L on the postoperative first day, the aspartic aminotransferase was (401±113)U/L on the postoperative first day, and the duration of postoperative hospital stay was (9±4)days. No bile leakage, hemorr-hage, reoperation or other complications occurred in all patients. (3) Follow-up: 10 patients were followed up for 7?13 months, with a median follow-up time of 11 months. All patients had no margin recurrence or distant metastasis. Conclusion:It is safe and feasible to construct triangular modal for planning approach of local laparoscopic resection of liver tumors located in superior part of central liver lobe.

Objective To analyze the clinical features,risk factors,imaging features and prognoses of cerebral infarction menifested as isolated acute vestibular syndrome (AVS) to improve the diagnoses and treatments of the disease.Methods Clinical data of 15 cerebral infarction patients menifested as isolated AVS,admitted to our hospital from October 2015 to April 2016,were summarized retrospectively.The clinical features,risk factors,imaging features and prognoses of these patients were analyzed.Results (1) Clinical characteristics:the average age of cerebral infarction patients menifested as isolated AVS was 62.1 ±13.5 years old,and the median attack time was 24 (4-168) h;the main clinical manifestations were vertigo,including nausea (n=1 1),vomiting (n=10),nystagmus (n=10),and unstable gait (n=14).(2) Risk factors:14 patients had multiple risk factors of stroke (＞4),and they were age,hypertension,hypedipidemia,diabetes,smoking,carotid stenosis,history of stroke,white matter degeneration,coronary heart disease,and atrial fibrillation.(3) Imaging features:14 patients were posterior circulation infarction,and the lesions were located in the cerebellar hemisphere (n=l 1),cauda cerebelli (n=4),pons (n=3),brachium pontis (n=1),brachium inferius cerebelli (n=1);inferior colliculus (n=1),and multiple lesions occurred in 6 patients;one anterior circulation infarction was located in the insula;most lesions were smaller lacunar infarcts,but the lower part of cerebellar hemisphere was mostly larger infarct.(4) Prognoses:the prognosis of patients is good after regular treatment,9 had complete symptom relief,and 6 got improvement.Conclusions When patients presented with isolated AVS and many risk factors exist in clinic,the possibility of cerebral infarction should be taken into account.Such patients should be subjected to relevant examinations in a timely manner and early diagnosis,so that they can get regular treatment as soon as possible and prognoses can be improved.

OBJECTIVETo investigate the effect of fuzheng quxie granule (FQG) on immune cells and cytokines in populations with respiratory viral infection.

METHODSFifty-nine patients were randomly divided into 3 groups, that is, 19 patients treated with conventional western medicine (WM) plus FQG in the treated group, 19 patients treated with conventional western medicine alone in the WM group, and 21 patients treated with FQG alone in the TCM group. The levels of T lymphocyte subsets, interleukine-2,4,6,10 (IL-2, IL-4, IL-6, IL-10), tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (INF-gamma) and Th1/Th2 were determined before treatment, and at the end of 1st and 2nd week of treatment respectively.

RESULTSBefore treatment, levels of TNF-alpha, IL-2, IL-6, IL-10 and INF-gamma in all patients were significantly higher than normal range (P < 0.05). After being treated for 1 week, the levels of serum TNF-alpha, IL-6, and IL-10 were significantly decreased in all groups (P < 0.05), serum IL-2 and INF-gamma decreased to the normal level in the WM group, but in the treated and the FQG group by the end of the 2nd week, the two indexes still remained at the rather higher level (P < 0.05). The ratio of Th1 and Th2 in the treated group and the FQG group increased significantly by the end of 2nd week, reached the level higher than that in the WM group and that before treatment (P < 0.05). No significant difference in, T lymphocytes subsets (CD3+ , CD4+ , CD8+) and percentage of B and NK cells before and after treatment was found in all the 3 groups.

CONCLUSIONFQG can positively regulate the immune function of patients with respiratory tract viral infection in certain degree.
