OBJECTIVE: To investigate the effects of electroacupuncture (EA) on endolymphatic hydrops (EH) and the regulation of arginine vasopressin (AVP)-aquaporin-2 (AQP2) pathway in guinea pigs. METHODS: EH was induced in male guinea pigs by an intraperitoneal injection of AVP. For the treatment, EA was delivered to Baihui (GV 20) and Tinggong (SI 19) acupoints, once per day for 10 consecutive days. In histomorphological studies, cochlear hydrops degree was evaluated by hematoxylin-eosin (HE) staining, and then the ratio of scala media (SM) area to SM + scala vestibuli (SV) area (R value) was calculated. In mechanical studies, a comparison of plasma AVP (p-AVP) concentrations, cyclic adenosine monophosphate (cAMP) levels, vasopressin type 2 receptor (V2R) and AQP2 mRNA expressions in the cochlea were compared among groups. RESULTS: EA significantly reduced cochlear hydrops in guinea pigs (P=0.001). EA significantly attenuated the AVPinduced up-regulation of p-AVP concentrations (P=0.006), cochlear cAMP levels (P=0.003) and AQP2 mRNA expression (P=0.016), and up-regulated the expression of V2R mRNA (P=0.004) in the cochlea. CONCLUSIONS The dehydrating effect of EA might be associated with its inhibition of AVP-AQP2 pathway activation.

OBJECTIVE: To analyze the 5 experimental indexes of CDSS in the patients with acute leukemia (AL) so as to provide the laboratorial basis for the early diagnosis and treatment of the secondary DIC in AL. METHODS: Three hundred and thirty three patients with AL were divided into 7 groups, such as AML-M1-M5, other AML and ALL. The experimental indexes and CDSS scores of all AL groups were compared and analyzed in pairs, meanwhile 100 healthy persons were taken in the control group. Clinical events such as early death in all cases were also analyzed. RESULTS: The highest positive rate of Platelet was 59.76%, among the 5 experimental indexes, followed by D-D (30.93%), and the lowest APTT with only 2.70%. Compared with the control group, the differences of remaining indexes were statistically significant (P＜0.01), except APTT in group AML-M3 and FIB in the other AML groups. The score of laboratory index was (1.50±1.51) in all AL patients, and the positive rate of overt DIC ( score≥4) was 14.11% ( 47 cases). The highest score of CDSS was (3.34 ±1.71) in group AML-M3. The difference in the incidence of early death and cerebral (pulmonary) hemorrhage in DIC patients were statistically significant (P＜0.05 and P＜0.01). CONCLUSION The application of quantitative integral method of experimental indexes in CDSS is objective and feasible, which is of great significance for early diagnosis and early treatment of acute leukemia complicated with DIC.

BACKGROUND: Surgical site infection is the main complication after posterior lumbar surgery, which not only increases the patient's hospitalization time, financial burden and physical pain, but also increases the difficulty for the clinical medical staff, delays the recovery of postoperative patients, even leads to deaths. Therefore, it is important to analyze the factors related to the infection of the surgical site after posterior lumbar surgery. OBJECTIVE: To analyze the risk factors of the surgical site infection after lumbar posterior approach in China. METHODS: Studies about the surgical site infection after lumbar posterior approach were retrieved by computer. The quality of the studies was evaluated by reading the full text. Heterogeneity was analyzed using RevMan 5.3 software. Meta analysis was used to analyze the combined effect. RESULTS AND CONCLUSION: (1) Totally 20 studies with 423 cases of surgical site infection and 13 995 cases of non-infection were included. (2)Meta-analysis univariate analysis results:body mass index ≥ 27 kg/m2[OR=3.82,95%CI(2.47,5.91),P<0.000 01],age ≥ 60 years [OR=1.99,95%CI(1.44,2.76),P<0.000 1],intraoperative blood loss ≥ 300 mL[OR=3.98,95%CI(2.50,6.33),P<0.000 01],subcutaneous fat thickness[MD=5.35,95%CI(3.58,7.12),P<0.000 01],number of segments ≥ 3[OR=3.83,95%CI(2.02,7.26),P<0.000 1],operation time ≥180 minutes[OR=2.96,95%CI(2.06,4.27),P<0.000 01],preoperative serum protein<35 g/L[OR=2.37,95%CI(1.63,3.46),P<0.000 01],and diabetes[OR=2.88,95%CI(2.22,3.74),P<0.000 01]were risk factors for surgical site infection after lumbar posterior approach.(3)Multivariate analysis results:body mass index ≥ 27 kg/m2[OR=3.21,95%CI(1.97,5.22),P<0.000 01],subcutaneous fat thickness[MD=5.35,95%CI(3.58, 7.12),P<0.000 01],preoperative serum protein<35 g/L[OR=3.73,95%CI(2.30,6.04),P<0.000 01],and diabetes[OR=3.35,95%CI(1.75,6.42), P=0.003]were independent risk factors for surgical site infection after lumbar posterior surgery.(4)Results showed that body mass index ≥27 kg/m2, subcutaneous fat thickness, preoperative serum protein < 35 g/L, and diabetes are independent risk factors for surgical site infection after lumbar posterior approach in China. Due to the number of cases of surgical site infection and its methodological quality during the study, the above conclusions still need to be confirmed by more large-scale, high-quality studies to provide reliable evidence for perioperative management.

Objective To explore the clinical effect of non-invasive positive pressure ventilation(NPPV)for treatment of acute left heart failure after mitral valve replacement. Methods Sixty patients with acute left heart failure after mitral valve replacement in Xinxiang Central Hospital from April 2009 to August 2017 were selected. The patients were divided into control group and NPPV group,with 30 patients in each group. The patients in the control group were treated with double oxygen ab-sorption (mask and nasal catheter),strong heart,diuresis and dilated blood vessels. Based on the treatment of control group, the patients in NPPV group were treated with NPPV therapy. The plasma N-terminal pro-B-type natriuretic peptide(NT-proB-NP)level of patients in the two groups was monitored by rapid determination of immunofluorescence before treatment and 6,24 hours after treatment. The respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure monitoring of patients in the two groups was monitored before treatment and 2,6 and 24 hours after treatment. Results The total effective rate of patients in the control group and NPPV group was 92. 4％(26 / 28)and 96. 6％(28 / 29)respectively;there was no sig-nificant difference in the total effective rate between the two groups(χ2 = 1. 25,P > 0. 05). There was no significant difference in the plasma NT-proBNP level between the two groups before treatment (P > 0. 05);the level of NT-proBNP at 6,24 h after treatment was significantly lower than that before treatment in the two groups (P < 0. 05);the level of NT-proBNP of patients in the NPPV group was significantly lower than that in the control group at 6,24 h after treatment (P < 0. 05). There was no significant difference in the respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure between the two groups before treatment(P > 0. 05). Compared with before treatment,the respiratory frequency and heart rate of patients were decreased and the blood oxygen saturation,oxygen partial pressure were increased at 2,6,24 h after treatment in the two groups (P < 0. 05). There was no significant difference in the oxygen partial pressure between the two groups at 2 h after treat-ment(P > 0. 05);the oxygen partial pressure of patients in the NPPV group was significantly higher than that in the control group at 6,24 h after treatment(P < 0. 05);there was no significant difference in the respiratory frequency,blood oxygen satu-ration and heart rate between the two groups at each time piont after treatment(P > 0. 05). Conclusion NPPV is an effective treatment for acute left heart failure after mitral valve replacement.

OBJECTIVETo investigate the presence of leukemia stem cells (LSC) in acute myeloid leukemia (AML) and find out the relative position of leukemia cells in the figures of flow cytometry, and to analyze the relationship between minimal residual diseases (MRD) and the level of LSC, so as to explore the correlation of LSC changes with the curative effect and the prognosis during chemical therapy.

METHODSA total of 85 samples were collected from 50 AML (except M3) patients, including 50 samples from the newly diagnosed patients, 7 samples of AML patients with non-remission and 28 samples of AML patients with complete remission. All samples were used for detection of LSC from immune phenotype of CD34/CD38/CD123 by flow cytometry. The detection of immune phenotypic of leukemia cells was performed in the newly diagnosed patients. The detection of leukemia- associated immune phenotypes (LAIP) was implemented in the non-newly diagnosed patients.

RESULTSThe LSC was identified in the CD34/ CD38/ CD123 in AML and consistent with the relative position of the leukemia cell in flow cytometry figures. Statistical analysis showed significant difference in LSC content between the newly diagnosed AML group and the post-chemotherapy complete remission group(P<0.01),but did not between the newly diagnosed AML group and the post-chemotherapy non-remission group(P>0.05).There was significant positive correlation between the LSC content and MRD level in 28 AML patients with complete remission (r=0.680,P<0.01).

CONCLUSIONLSC exist in AML and the relative position are consistent with the leukemia cells in flow cytometry figures, the size characteristics and weak expression of CD45 are also similar to leukemia cells. The proportion of LSC decreases after chemotherapy. Detecting and tracking the LSC changes in bone marrow and combination with detecting minimal resident disease(MRD) may contribute to evaluate the theraputic efficacy and prognosis of leukemia patients.

ObjectiveTo investigate the clinical efficacy and safety of Huanshao Capsules (HSC) in the treatment of oligoasthenospermia with spleen and kidney asthenia.

METHODSThis randomized, open, multicentered, positive drug controlled clinical trial included 200 cases of oligoasthenospermia with spleen and kidney asthenia, which were assigned to a trial and a control group of equal number to be treated with HSC at the dose of 3 capsules tid and Wuziyanzong Pills at 6 g bid, respectively, both for 12 weeks. We compared the semen volume, sperm concentration, sperm count, sperm motility and percentage of progressively motile sperm (PMS) as the main therapeutic indicators as well as the pregnancy rate as the secondary therapeutic indicator between the two groups of patients before and at 4, 8 and 12 weeks after medication.

RESULTSTotally, 190 of the patients completed the clinical observation, 96 in the trial and 94 in the control group. Compared with the baseline, the patients of the trial group showed significant time-dependent increases at 4, 8 and 12 weeks after medication in the mean sperm concentration (14.78 vs 15.33, 20.98 and 28.78 ×10⁶/ml, P < 0.05), percentage of grade a sperm (12.17% vs 15.05%, 21.17% and 26.97%, P < 0.05), PMS (24.78% vs 28.97%, 37.23% and 47.67%, P < 0.05), and sperm viability (38.64% vs 44.18%, 51.67% and 60.45%, P < 0.05). The pregnancy rate was significantly higher in the trial than in the control group 29.17% vs 18.09%, P < 0.05).

CONCLUSIONSHuanshao Capsules can improve the semen quality and pregnancy rate in the treatment of oligoasthenospermia patients with spleen and kidney asthenia, and therefore deserves a wide clinical application.

OBJECTIVETo analyze the clinical effect of spinal cord decompression and lavage therapy on chronic cervical spinal cord injury and explore the possible mechanism.

METHODSFifty-seven patients with chronic cervical spinal cord injury treated in our hospital from January, 2008 to January, 2015 were enrolled, including 17 with multilevel cervical disc herniation, 25 with long segmental ossification of the posterior longitudinal ligament, 13 with hypertrophy or calcification of neck ligamentum flavum, and 2 with old cervical fractures. Open-door spinal canal laminoplasty via a posterior approach and decompression in simple extramedullary decompression was performed in 31 cases (group A), and open-door spinal cord incision decompression via a posterior approach, saline irrigation, and spinal canal laminoplasty in intramedullary decompression was performed in 26 cases (group B). The pre-operative cerebrospinal fluid in group B patients was collected to examine the inflammatory factors. All the patients were followed up and evaluated for pre- and postoperative JOA scores to calculate the improvement rate with regular examinations by X-ray, CT or MRI.

RESULTSImaging examinations 2 weeks after the operation showed obvious relief of the primary lesion in both groups, and the improvement of high signals was better in group B than in group A. The mean improvement rate at 12 months after the operation was 52.33% in group A and 61.52% in group B (P<0.05), and the mean JOA score was significantly higher in group B than in group A (14.80∓1.51 vs 13.58∓0.56; P<0.05). Cerebrospinal fluid leakage occurred in 3 cases, epidural hematoma in 2 cases, internal fixation loosening in 1 case in group A; portal shaft fracture and internal fixation loosening occurred in 1 case in group B. Postoperative recovery time was shorter in group B and entered the platform phase in 3 months. The inflammatory factors IFN-γ, IL-17F, IL-6 and sCD40L were all significantly higher than the normal levels after spinal cord injury, and the increment of IL-6 was the most conspicuous (P<0.05).

CONCLUSIONIntramedullary and extramedullary decompression can achieve better outcomes than extramedullary decompression in patients with chronic cervical cord injury. This may be related not only to relieving adhesions and secondary compression by cutting the dura under the microscope, but also to removal of local inflammatory factors.
