Abstract: Objective To analyze a case of bloodstream infection caused by Ureaplasma urealyticum after abortion in Anxi County Hospital, so as to provide basis for the clinical diagnosis and treatment. Methods　The diagnosis of Ureaplasma urealyticum in this patient with bloodstream infection was retrospectively analyzed. The basic clinical data and laboratory diagnosis data were collected, including the characteristics of blood culture curve, Wright staining of culture medium, drug sensitivity of Mycoplasma liquid identification, colony characteristics of solid medium, and the conclusion of targeted DNA sequencing. Through the comprehensive analysis of the above data, the rapid diagnosis of this case can be realized by optimizing the detection and diagnosis process. Results　The clinical manifestations of this patient were fever of 38.5 ℃, CRP:14.85 mg/L, WBC:14.33×109/L, NET: 85.40%, PCT: 0.12 ng/mL, IL-6: 665.6 pg/mL, positive after 3 days of blood culture, no bacteria were found in Gram stain, and sand-like purple bacteria were observed after adding Wright's stain. After inoculation in blood agar, Mycoplasma solid and liquid medium, no colonies were grown in blood agar, after 48 h and 5 d. On Mycoplasma A7 agar, the edge of brown fried egg colony was striature, and it could be identified as Ureaplasma urealyticum with the Mycoplasma ID & AST panel, which was resistant to quinolones and spectinomycin, but sensitive to macrolides, tetracyclines and lincomycin. Subsequent targeted DNA sequencing results were also confirmed for Ureaplasma urealyticum. Before receiving the report, clinical experience treatment with ceftriaxone metronidazole was used to fight infection with negative bacilli and anaerobic bacteria. Mycoplasma was not treated with targeted treatment. After 3 days, the patient's body temperature returned to normal, inflammation index decreased, and the patient asked to be discharged. Conclusions　At present, there are few reports of bloodstream infection caused by Ureaplasma urealyticum, and the lack of clinical understanding can easily lead to misdiagnosis and missed diagnosis. In order to improve the detection rate of Mycoplasma in blood culture, it is necessary to optimize the detection procedure of blood culture and provide accurate diagnosis and treatment basis for clinical practice. However, it is clear from this case that Mycoplasma bloodstream infection cases are self-limited infection and can recover by themselves without targeted treatment in patients with normal immunity. Therefore, it is very important to protect the immunity of patients.

Objective To study the neuroprotective effect of orexin-B on rat model of cerebral ischemia-reperfusion injury and its molecular mechanism. Methods The artery occlusion model of male Wister rats(middle cerebral ar-tery occlusion,MCAO) was established which has been ischemic 2 h and reperfusion 24 h. Rats were randomly di-vided into sham group (control), ischemia-reperfusion group (I/R), ischemia-reperfusion +PBS group (I/R+PBS),and ischemia-reperfusion +orexin-B group (I/R+OXB). The neurological deficit scores were processed to inclusion and exclusion. Infarct size was determined by TTC staining;Using Western blot,the expressions of orexin receptor 2,p-AKT,p-GSK-3β proteins in hippocampus were detected;Jumping test was used to detect learning and memory abilities in rats. Results Orexin-B significantly reduced the volume of cerebral infarction in TTC staining;orexin-B group was significantly increased the expression of orexin receptor 2as well as p-AKT,which decreased p-GSK-3β (P<0.05),compared with the untreated group. Furthmore,the orexin-B treated group can improve the latency period and decline the mistakes in rat Jumping test(P<0.05). Conclusions The neuroprotective effect of orexin-B in cerebral ischemia-reperfusion injury may enhance p-AKT activity and inhibit p-GSK-3β activity,which may increase the proliferation of neurons and improve the cerebral blood glucose concentration.

OBJECTIVE To assess the efficancy of Yangxue Qingnao granules on simvastatin-induced vascular injury model in zebrafish. METHODS Since statins can inhibit vascular development in zebrafish,in this study,we developed a novel animal model using 1 to 3 day post-fertilization larval zebrafish by optimizing the doses and duration of simvastatin exposure.Five pro-angiogenic drugs with a variety of mechanisms were tested to validate the newly developed zebrafish model. Zebrafish was treated with different concentration of Yangxue Qingnao granules( 62.5,125 and 250 μg·mL-1)for 2 d then tested for the area of subintestinal vein vessels. RESULTS Vascular regeneration promoting effect of five pro-angiogenic drugs (calycosin, astragaloside, chlorogenic acid, ferulic acid and Panax Notoginseng Saponins)were 8-48%,24-51%,35-58%,28-75% and 37-69%,respectively.In 62.5,125 and 250 μg·mL-1Yangxue Qingnao granules group,vascular regeneration promoting effect were 21% (P>0.05), 84%(P<0.01) and 53%(P<0.01). CONCLUSION Our results demonstrate that the zebrafish vascular injury model validated in this study could be used for in vivo angiogenesis studies and drug screening and for assessing pro-angiogenic drugs with different mechanisms.Yangxue Qingnao granules could promote the vascular regeneration in zebrafish.

OBJECTIVE: To evaluate decision regret among patients receiving penile girth enhancement with acellular dermal matrix (PGE with ADM) and to investigate the potential indicators for decisional regret so as to facilitate the decision-making process for this special group. METHODS: In the study, 78 patients receiving PGE with ADM from Jun. 2016 to Jan. 2019 at Peking University People's Hospital and cooperative hospitals were eligible. Penile girth was taken by only one surgeon 1 week before surgery. Hospital anxiety and depression scale (HAD), international index of erectile function (IIEF) and a 10 cm long visual analogue scale named visualized penile image (VPI) were applied to measure psychological burden, erectile function and satisfaction with penile image respectively at the same time. All the patients were followed up for 3 months. Decision regret scale (DRS) was adopted for measuring decisional regret. Multivariate analysis of variance was applied to investigate the potential indicators for regret. Data analysis process was conducted with SPSS (version 24.0; SPSS, Chicago, IL, USA). RESULTS: Mean penile girth recorded before intervention was (8.29±0.30) cm and increased to (9.46±0.29) cm post surgery (t=76.28, P < 0.01). As for both subscales of HAD measuring psychological burden, a signi-ficant reduction in the mean score was seen, that is, 2.8±1.3 (t=19.28, P < 0.05) for anxiety and 3.0±1.2 (t=20.67, P < 0.05) for depression, respectively. The average score of VPI increased by 3.7±1.1 (t=30.63, P < 0.05). There was no significant change in the average score of IIEF measuring erectile satisfaction (t=1.60, P=0.11). Twenty-nine (38.2%) patients expressed regret to some degree, and the mean DRS score was 23.4±14.8. The scores of DRS correlated negatively with scores of visualized penis image (r=-0.348, P < 0.01), and positively with scores of anxiety (r=0.760, P < 0.01) and depression subscale (r=0.471, P < 0.01). The scores of DRS was irrelevant to those of IIEF (r=0.02, P=0.867). The patients with high annual income (> 120 000 yuan) and education level above undergraduate were more prone to experience decision regret after intervention (P < 0.01). CONCLUSION PGE with ADM did augment penile girth and lower psychological burden, the regret rate of which was acceptably low among the patients. High income and good education might indicate more post-operative regret. Additional decision-making aids should be offered to patients with high income and education level above high school.

OBJECTIVETo explore the clinical effects and significances of a cervical anterior Hybrid technique with posterior longitudinal ligament retained in treating cervical spondylosis.

METHODSThe clinical data of 138 patients with cervical spondylosis underwent cervical anterior Hybrid surgery were retrospectively analyzed from March 2009 to March 2013. There were 52 males and 86 females,the age ranged from 36 to 58 years old with an average of 45.3 years. Course of disease was from 3 to 16 months. Cervical spondylosis classification included 22 cases with nerve root type, 68 cases with myelopathic type, 48 cases with mixed type. All patients were treated with the primary Hybrid surgery and their cervical posterior longitudinal ligaments were retained in anterior decompression. JOA score and image examination were used to evaluate clinical effect, and image examination included range of motion of the replacement segment, range of motion of the whole cervical spine, the sagittal diameter of the spinal cord before and after operation.

RESULTSAll operations were successful and operation time was 60 to 125 min (averaged 90.6 min), perioperative bleeding was 10 to 60 ml (averaged 30.1 ml). All patients were followed up from 12 to 48 months with an average of 22.2 months. All pathological segments obtained fully decompression, reserved posterior longitudinal ligament had no obvious hypertrophy, proliferation and calcification. The prosthesis had good location and the incision healed well without complications. Upper limbs root symptoms were completely relieved in the patients with cervical spondylotic radiculopathy, muscle strengths and sensations got different recovery in the patients with cervical spondylotic myelopathy. JOA score was increased from preoperative 8.62±1.22 to final follow-up 14.26±1.47 (P<0.05). Artificial intervertebral discs were stabilized in the patients, the replacement segment and range of motion of whole cervical spine were respectively (14.2± 5.6)° and (33.8±10.3)°, there was no significant differences between preoperative and postoperative (P>0.05). Spinal cord sagittal diameter was increased from preoperative (5.2±1.3) mm to postoperative (8.8±0.5) mm (P<0.05).

CONCLUSIONAnterior cervical Hybrid surgery with posterior longitudinal ligament retained can achieve fully decompression and good clinical efficacy, we recommend retaining the normal posterior longitudinal ligament in surgery as complete as possible.

Objective To discuss the effect of psychological nursing on HIV/AIDS patients with anxiety and depression.Methods 40 HIV/AIDS patients with anxiety and depression were randomly divided into intervention group (20 cases) and control group (20 cases).Hamilton anxiety rating scale (HAMA) and Hamilton depression rating scale (HAMD) were used to evaluate the effect at 4 weeks and 3 months of the research.Results HAMA and HAMD scores of the intervention group at 4 weeks and 3 months were significantly lower than the control group [(15.30±4.12) vs (19.70±5.89),(13.00±2.51) vs (18.20±3.27),(5.70±2.57) vs (14.35 ±4.20),(7.50 ±3.19) vs (14.55 ±3.68),t =5.64,8.817,2.737,5.808;P ＜0.01].Conclusions Psychological nursing could greatly relieve the negative emotions of HIV/AIDS patients and promote treatment and nursing effect.

OBJECTIVETo assess the efficacy and safety of recombinant human thrombopoietin (rhTPO) on chemotherapy-induced thrombocytopenia in patients with solid tumor.

METHODSIn this randomized crossover self-controlled multi-center clinical trial, 154 patients with solid tumor were randomly divided into two groups (group A 77 cases and group B 77 cases). All patients were given the same two cycles of chemotherapy. In group A, the first cycle was treated cycle, in which patients were given rhTPO, while the second cycle was non-treated cycle as a control. In group B, the first cycle was non-treated cycle as a control, while the second cycle was treated cycle. RhTPO 1.0 microg/(kg x d) was administered subcutaneously 6-24 hours after chemotherapy for the longest 14 days. Laboratory tests included complete blood counts, urinalysis, serum chemistry, coagulant test, chest radiography, and electrocardiogram. Serum samples were screened for anti-rhTPO antibodies.

RESULTSIn both group A and group B, platelet decrease and duration had no significant difference between the treated cycle and non-treated cycle. Platelet count was higher in the treated cycle, than in the non-treated cycle: [minimal mean platelet count (64.4 +/- 45.4) x 10(9) cells/L and (52.4 +/- 30.9) x 10(9) cells/L (P=0.000), maximal mean platelet count (263.9 +/- 142.5) x 10(9) cells/L and (148.9 +/- 67.7) x 10(9) cells/L (P=0.000)]. Duration of thrombocytopenia was shorter in the treated cycle than in the non-treated cycle [days with platelet count < 50 x 10(9) cells/L, (2.5 +/- 3.9) and (3.7 +/- 5.7) (P=0.04); days with platelet count recovered > or = 75 x 10(9) cells/L, (10.3 +/- 8.7) and (14.0 +/- 8.9) (P=0.000), and days with platelet count recovered > or = 100 x 10(9) cells/L, (15.9 +/- 10.5) and (21.1 +/- 9.5) (P=0.000)]. The need for platelet transfusion was not significantly reduced in treated cycle. The effects of rhTPO on WBC, Hb, hepatic function, renal function, and coagulant function were not found. Transient low-titer non-neutralizing antibody was developed in one patient. Therapy with rhTPO was tolerated by all patients. Mild side effects were observed in individual patients, including fever, dizziness, and chill. Conclusion Administration of rhTPO after chemotherapy can significantly reduce the degree and duration of thrombocytopenia and promote platelet recovery. Therapy with rhTPO seems to be safe.
