Objective To understand the clinical distribution characteristics of Acinetobacter baumannii in our hospital and the change situation of drug resistance rates to provide a basis for the clinical rational drug use and the nosocomial infection manage-ment.Methods The Acinetobacter baumannii strains isolated in our hospital from January 2005 to December 2013 were performed the retrospective analysis on its department distribution,specimen distribution and change of drug resistance rates.Results 964 strains of Acinetobacter baumannii were isolated during these 9 years,in which 713 strains were multi-drug resistant.The isolated strains were less during 2005 -2008,which were 30,26,22,19 strains respectively.The isolated strains began to increase during 2009-2010,which were 65,50 strains respectively.The detection rate began to enormously increase from 2011,which were 157, 229,366 strains respectively from 2011 to 2013.The top three departments of the highest isolation rates during these 9 years were ICU,neurosurgery department and respiratory department.The specimen source was always dominated by the respiratory tract specimens,followed by the secretion samples,in recent years,the detection rates of blood,urine and drainage specimens were in-creased to some extent.The drug resistance rates in 13 kinds of drugs totally showed the increasing trend,the resistance rate of par-tial drugs was decreased to some extent.Conclusion Acinetobacter baumannii easily cause nosocomial infections,which is difficult to be eliminated and has high occurrence in the departments centralized with critical patients.The respiratory infection is the main pathogenic type.Its drug resistance is serious,multi-drug resistant and pan-resistant strains have the higher proportion.Clinic should rationally use the drugs based on the drug susceptibility test results,coordinates with the infection control departments for doing disinfection and isolation well and prevent ing the outbreak of nosocomial infections.

The cholinesterase(ChE)and lactate dehydrogenase(LDH)activities in blood smears of 37 patients were observed before and 20 minutes after electroacupuncture.Hegu and Zusanli were mainly chosen as the acupuncture points.Karnovsky method was used to demonstrate ChE,activity,and tetrazolium-formazan reaction for LDH activity. Before acupuncture,all formed elements of blood showed both ChE and LDH acti- vities.In red blood cells ChE and LDH activities were localized at the cell membrane, while in white blood cells they were found throughout the cytoplasm as colored granu- les.The granulocytes showed greater ChE and lesser LDH activities than the lymph- ocytes.The platelets also showed greater LDH and ChE activities,especially the former. On the whole,platelets and leucocytes,as compared with erythrocytes,showed greater activities for ChE and LDH. Under microscopic observation,according to the amount and color of granules,the degrees of GhE and LDH activities for each kind of blood formed elements before and after acupuncture were recorded as different markes,such as +、++、+++ and so on.The degrees of GhE or LDH activity in various formed elements of blood were compared by means of statistical tests.After acupuncture,both GhE and LDH activities of all blood formed elements were increased(p

70 patients including 60 cases under acupuncture anesthesia and 10 cases under drug anesthesia were observed. Before and 20 minutes after acupuncture the blood samples were taken from the patient ear lobes respectively, and in some patients taken once again 24 hrs after acupuncture. The electroacupuncture point Hegu or Zusanli was mainly adopted. As the method for detection of cell-mediated immunity(CMI) in vitro the improved microtechnique of whole blood for E-rosette (active and nonactive) and lymphocyte transformation tests was used. In performance of active rosetting the total leucocyte count and the differential lymphocyte count were done for calculation of absolute number of active rosette forming cells (RFC). The mean value of increase of active RFC was 12.7?1.43, the decrease was 6.8?1.77 after acupuncture. The increment of the absolute number of active RFC was 175?63.59. However no marked effect on the drug anesthesia group was found. In the lymphocyte transformation assay the increase was 12.7?1.49, the decrease was 7.0?2.19, and the enhancement effect still exhibited 24 hrs after acupuncture. In these tests an increase was mostly found in those with a lower or a usual CMI level; a decrease often found in those with a higher CMI level prior to acupuncture. The increase or decrease level in the results of three kinds of test (active, nonactive RFC and lymphocyte transformation) was similar, the increase range was 12～13%, the decrease range 6～7%. As the former compared with the latter, the promotion was prominent by all means.

Objective:To explore the calvarial critical size defect (CSD)in rats with type 2 diabetes mellitus(T2DM).Methods:T2DM model of SD rats(weighted 300-320 g)was induced by high fat and high sugar diet and low dose intraperitoneal streptozotocin (STZ)injection.The rats with T2DMand the normal controls were divided into 4 groups(n=3)respectively.Defects with the diame-ter(mm)of 2,3,4 and 5 were made on the central calvaria of each rat.General observation,X-ray examination and histological study were performed 8 weeks postoperatively.Results:In the T2DM group,only the defects of 2 mm diameter were healed completely,X-ray resistance and new bone formation were observed;the defects of 3,4 and 5 mm diameter were unhealed,X-ray transmission was observed and newly formed bone was insufficient.In the control group,the defects of 2,3 and 4 mm diameter were healed completely, X-ray resistance and new bone formation were observed;the defects of 5 mm diameter were unhealed,X-ray transmission was ob-served,newly formed bone was insufficient.Conclusion:The calvarial CSD of T2DM rat model can be defined as the defect with the diameter of 3 mm.

Objective To study the mutation of FLCN gene in Chinese patients with sporadic and familial primary spontaneous pneumothorax. Methods A complete genetic analysis of FLCN by use of SSCP-PCR was performed in 102 unrelated Chinese patients with isolated PSP. Results Three novel mutations (c. 924_926del, c. 1611_1631del and c. 1740C.T) and a previously reported mutation (c. 1733insC) were identified in five familial and five sporadic PSP patients. Of the 21 family members of patients with PSP including 3 previous considered as sporadic, 4 ( 19% ) had history of at least one episode of PSP and 9 (43% ) were FLCN mutant carriers without PSP. Seven of the nine (78% ) mutant carriers had pulmonary cysts detected by high-resolution computed tomography ( HRCT) . Although c. 924_926del and c. 1611 _1631 del were found in eight patients from the same geographic district, haplotype analysis demonstrated that they did not share the same affected haplotype,thus excluding common ancestry. Conclusion This study first demonstrates that FLCN mutation contributes to not only familial but also apparently sporadic' patients with isolated PSP. It suggests that mutation analysis and HRCT scan may be recommended for first-degree family members of PSP patients with FLCN mutations, irrespective of their family history status of PSP.

Objective:To explore the prevalence, clinical features, genetic characteristics and prognosis of Citrin deficiency in Henan province of China.Methods:A total of 986 565 neonates screened by tandem mass spectrometry at the Third Affiliated Hospital of Zhengzhou University from January 2013 to December 2021 were retrospectively analyzed. Analysis of SLC25A13 gene variants and parental verification were carried out for neonates suspected for Citrin deficiency by next-generation sequencing. The clinical, biochemical and genetic characteristics of Citrin deficiency patients were integrated to guide the diet treatment and follow up the growth and development. Paired- t test was used to compare the amino acid levels in the peripheral blood samples before and after the treatment. Results:Nine cases of Citrin deficiency were diagnosed among the 986 565 neonates. Specific elevation of citrulline was observed in all of the 9 cases. Six variants were detected by genetic sequencing, among which c. 852_855delTATG, c. 615+ 5G>A, c. 550C>T and IVS16ins3kb were known pathogenic variants, whilst c. 1111_1112delAT and c. 837T>A were unreported previously. The detection rate for c. 852_855delTATG was the highest (61.6%, 11/18), followed by IVS16ins3kb (16.7%, 3/18). The clinical symptoms of all patients were relieved after the treatment, and the blood amino acid profile and biochemical parameters were significantly improved by gradually falling within the normal range. By June 2022, all patients had shown a good prognosis.Conclusion:The prevalence of Citrin deficiency among neonates from Henan Province by tandem mass spectrometry is 1/109 618, and the carrier rate for the pathogenic variants of the SLC25A13 gene was 1/166. The c. 852_855delTATG may be a hot spot variant among the patients. Discovery of the novel variants has enriched the mutational spectrum of the SLC25A13 gene. Above results have provided a basis for the early diagnosis, treatment, prognosis and genetic counseling for the affected families.
