OBJECTIVETo explore the effects of rotatory reduction manipulation and acupoint massage on blood flow velocity of vertebrobasilar artery (VBA) in younger cervical vertigo of high velocity,and to observe the difference of clinical therapeutic effect between two manipulations.
METHODSSeventy-six patients who diagnosed as high flow velocity of younger cervical vertigo were randomly divided into rotatory reduction manipulation group (group A, 38 cases)and acupoint massage group (group B, 38 cases). The changes of flow velocity of VBA before and after treatment were observed using transcranial Doppler (TCD) and the therapeutic effects were observed also.
RESULTSThe mean flow velocity in left vertebral artery (LVA)and basilar artery (BA)of group B and in BA of group A were significantly decreased as compared with those before treatment (P < 0.05, P < 0.01) 1 week after treatment,and there was significant difference in the change of mean flow velocity in LVA between two groups (P < 0.01). The mean velocity in LVA, right vertebral artery (RVA) and BA were obviously lower than thosfre before treatment in two groups (P < 0.01) 3 weeks after treatment. There was obvious difference in LVA, RVA between two groups (P < 0.01). The therapeutic effect of group B was superior to that of group A (P < 0.05).
CONCLUSIONThe effect of acupoint massage on flow velocity of VBA was superior to that of rotatory reduction manipulation, and the therapeutic effect of acupoint massage might be better than that of rotatory reduction manipulation in treating younger cervical vertigo of high flow velocity.

Abstract: Objective To investigate the epidemiological characteristics of pathogens causing bloodstream infection in hematology patients during treatment and to compare the effects of allogeneic hematopoietic stem cell transplantation (HSCT) on them, so as to provide evidence for the diagnosis and treatment of bloodstream infection. Methods A total of 292 cases with bloodstream infection in hematology wards of the PLA General Hospital were collected from 2017 to 2021, which were divided into HSCT group and N-HSCT group according to whether performed HSCT or not. The epidemiological characteristics and influence of pathogenic bacteria in blood stream infection were analyzed and compared between the two groups. Results A total of 362 strains of pathogenic bacteria were collected from 292 cases, including 106 strains in HSCT group (84 cases) and 256 strains in N-HSCT group (208 cases). Bloodstream infections were more common in acute myeloid leukemia (130/392, 44.52%), followed by non-Hodgkin's lymphoma (74/292, 25.34%). The rate of once bloodstream infection in HSCT group was higher than that in N-HSCT Group, but the rate of twice bloodstream infections in N-HSCT group was higher. Gram-negative Bacilli were the most common pathogens (56.08%), with Escherichia coli being absolutely dominant (109/362, 30.11%), followed by Klebsiella pneumoniae (39/362, 10.77%). Coagulase-negative staphylococci (CoNS) (107/362, 29.56%) were the most common Gram-positive cocci. The detection rate of fungi in HSCT group (10/106, 9.43%) was significantly higher than that in N-HSCT Group (3.52%). The drug resistance rate of the common pathogenic bacteria was at a high level, and there was a certain proportion of multi-drug resistant strains (except for Pseudomonas aeruginosa). The resistance rates of CoNS to penicillin, gentamicin, moxifloxacin, clindamycin and rifampicin in HSCT group were higher than those in N-HSCT Group. The resistance rate of Escherichia coli to piperacillin/tazobactam, cephalosporins and etapenem in HSCT group was significantly higher than that in N-HSCT group. Conclusions The pathogens of blood stream infection in hematology patients are complicated and various. It is difficult for clinical diagnosis and treatment to detect multiple infections and multiple pathogens. HSCT patients have a higher risk of fungal bloodstream infection and more multi-drug resistant strains detected. Therefore, the identification of bloodstream infection and multi-drug resistant strains associated with HSCT patients should prompt surveillance.

OBJECTIVETo explore the effect of minimally invasive Ivor-Lewis esophagectomy on acute phase responses in patients with esophageal carcinoma.
METHODSForty-eight patients with middle or low thoracic esophageal carcinoma underwent Ivor-Lewis esophagectomy. The patients were divided into small incision group (n = 25) and conventional group (n = 23) according to the patients' will. Serum levels of acute phase proteins C reactive protein (CRP), haptoglobin (HPT), α₁-acid glycoprotein (α₁-AG), ceruloplasmin (CER), transferrin (TRF), β₂-microglobulin (β₂-MG), album protein (ALB), interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) were measured and compared on 1st day before operation, at 18 hours as well as 3rd and 7th day after operation.
RESULTSThere was no significant difference in all the acute phase proteins indicators and IL-6 between the small incision and conventional groups at each time points after operation (P > 0.05). In both groups the levels of CRP, α₁-AG and HPT were significantly higher after operation than before operation (P < 0.05). The levels of ALB and TRF were significantly lower after operation than before operation (P < 0.05). The levels of CER and β₂-MG were not significantly different during perioperative period (P > 0.05). The level of TNF-α was significantly higher in the small incision group than that in the conventional group at the 18 hours postoperationally (P < 0.05), and were not significantly different on the other time points between the two groups (P > 0.05).
CONCLUSIONCompared with conventional operation, the small incision Ivor-Lewis esophagectomy do not significantly alleviate the stress of the surgical trauma in patients. Unchanging the essence of operation, if one is trying to minimize the stress caused by surgery on patients, the key factor is not the size of incision. An effective approach should be found in other operation-related factors.

This study was aimed to investigate the characteristics of human bone marrow mesenchymal stem cells during ex-vivo expansion, MSCs were isolated from human bone marrow. At each passage, the characteristics of proliferation kinetics, osteogenic and adipogenic differentiation potential were analyzed, and cell morphology, surface markers were investigated as well. The karyotype analysis was done in different passage cells. The infection HIV, HCV, HBV and TP were detected by ELISA. Mycoplasma contamination in vitro was detected by PCR method. HLA-SBT was used to reanalyze the results of HLA antigens and alleles. STR genetic loci were detected by PCR in the MSC1, MSC2, MSC3 and MSC4. The results indicated that the proliferative ability and osteogenic potential decreased with the increase of passage number during culture expansion. The multiple differentiation potential of MSCs was maintained during their life span. Karyotype analysis showed that MSCs from 4 groups before passage 8 were normal. The expression of CD29, CD44, CD105, CD166 and CD73 were positive. The expression of CD14, CD34, CD45, CD80, CD86 were all negative. SBT was used to identify HLA-A, B, Cw, DRB1, DRPB1, DQ alleles in the MSC1, MSC2, MSC3, MSC4. The genetype of STR in the MSC1, MSC2, MSC3, MSC4 was different. MSC 3 was examined by TP-ELISA to confirm the infectious disease of TP. MSC2 was contaminated by mycoplasma at passage 5. It is concluded that culture expansion causes MSCs to gradually lose their stem cell properties. During ex-vivo expansion of MSCs, the osteogenic differentiation potential is decreased. MSCs before passage 8 can be a valuable subject for basic research and clinical application.

OBJECTIVETo assess the influence of photoselective vaporization of the prostate (PVP) on the erectile function of the patient with benign prostatic hyperplasia (BPH).
METHODSUsing IIEF-5, we conducted a questionnaire investigation among 210 BPH patients before and after treated by PVP (n = 80) and transurethral resection of the prostate (TURP, n = 130). We also reviewed the clinical data and compared the pre- and post-operative penile erectile function between the two groups of patients.
RESULTSFollow-up was completed in 76 cases of PVP and 123 of TURP. The baseline data showed no statistically significant differences between the two groups in age, prostate volume, IPSS, QOL, Qmax, post void urine residual volume and IIEF-5 scores (P>0.05). Compared with the IEFF-5 score at the baseline (21.88 +/- 2.46), those at 3, 6 and 12 months after PVP were 16.72 +/- 3.17, 19.34 +/- 2.46 and 19.29 +/- 2. 18, respectively, significantly decreased at 3 months (P = 0.042), but with no remarkable difference at 6 and 12 months (P >0.05). Nor were there significant differences in the IIEF-5 score between the PVP and TURP groups at any time points (P>0.05). At 6 months after surgery, the incidence rates of erectile dysfunction were 11.7% and 13.7% in the TURP and PVP groups, respectively (P>0.05).
CONCLUSIONPVP may reduce erectile function in some cases in the early stage after surgery, but this adverse effect does not last long and is basically similar to that of TURP.

BACKGROUNDUntreated human cytomegalovirus (CMV) disease (CMVD) is an identified risk factor for reduced rates of patient (and graft) survival, death or retransplantation in kidney transplant recipients due to increased immunological tolerance after transplant. Vitamin D receptor (VDR) gene polymorphisms have an obvious relationship with autoimmune diseases but the relationship between VDR gene polymorphisms and CMVD are not well understood. This study investigated the relationship between VDR FokI and ApaI gene polymorphisms and CMVD, and their value for predicting risk of CMVD.
METHODSNinety-eight kidney transplantation recipients were randomly chosen for which peripheral blood samples and case histories for the first three months after kidney transplantation were obtained. Using polymerase chain reaction-restriction fragment length polymorphisms, 30 recipients were found to be homozygous for the FokI gene (FF), 47 heterozygous (Ff), and 21 were homozygous (ff). Likewise, similar analyses determined that 12 recipients were homozygous for the ApaI gene (AA), 36 heterozygous (Aa), and 50 homozygous (aa). Factors affecting the prognosis of the kidney transplantation were compared for all genotypes by statistical analysis before operation. Infection by CMV for all recipients was detected by immunofluorescence assay to diagnose CMVD.
RESULTSNo statistical significance was observed for the factors affecting the prognosis of the kidney transplantation between both genotypes; however, statistical differences in CMVD among the FokI genotypes were identified. It was determined that the risk of CMVD was significantly increased for recipients of the ff genotype than for other genotypes. There was no statistical significance observed for CMVD among ApaI genotypes.
CONCLUSIONSThe recessive f allelic gene of VDR can be regarded as a risk factor of CMVD while FF recipients have lower incidence of CMVD after kidney transplantation. ApaI genotypes showed no relationship with predisposition to CMVD.

OBJECTIVETo compare therapeutic effects of elongated needle therapy and routine acupuncture therapy on dysuria induced by benign prostatic hyperplasia (BPH).
METHODSRandomized, controlled, multi-central method was adopted and 150 cases confirmed to the enrolled criteria were divided into two groups by odd or even number, an elongated needle group (n = 72) and a routine acupuncture group (n = 78). Acupuncture was given at bilateral Zhibian (BL 54) and Zhongji (CV 3) in the two groups, once daily, 5 sessions constituting one course, with a 2-day interval between two courses. The treatment was given for 2 courses. Changes of I-PSS symptom cumulative score, urine flowing rate, residual urine in bladder before and after the treatment were observed.
RESULTSThe effective rate was 83.3% in the elongated needle group and 44.9% in the routine acupuncture group. There were significant differences between the two groups in improvemet of I-PSS score, increase of urine flowing rate and reduction of residual urine in bladder (all P < 0.05).
CONCLUSIONThe elongated needle therapy has a definite therapeutic effect on dysuria induced by benign prostatic hyperplasia.

The aim of the study is to evaluate the effects of the single and mixed decoction of Thallus laminariae (kelp) and Glycyrrhiza glabra (licorice) on the metabolism and their difference. The mixed decoction of kelp and licorice and the single decoction were made and intragastrically administered to the SD rats. The effect on system metabolism, the toxicity of liver and kidney were assessed by GC-MS profiling of the endogenous molecules in serum, routine biochemical assays and histographic inspection of tissues from SD rats, separately. The mixed decoction of kelp and licorice induced more obvious pathological abnormalities in SD rats than a single decoction of kelp, while the extracts of licorice did not show any pathological change. Neither the mixed, nor the single decoction showed abnormal histopathology. After intragastric administration of extracts for 5 days, the mixed decoction induced a decrease of ALT (no significant change in the groups of single decoction) and an increase of BUN (so did the single decoction of kelp). Metabolomic profile of the molecules in serum revealed that the metabolic patterns were all obviously affected for the three groups, i.e., the mixed and single decoction of kelp and licorice. The rats given with the single decoction of kelp showed a similar pattern to that of the mixed decoction, indicating that the kelp primarily contributed the perturbation of metabolism for the mixed decoction. All three groups induced a decrease of branched chain amino acids, TCA cycle intermediates and glycolysis intermediates (e.g., pyruvic acid and lactic acid) and an increase of 3-hydroxybutyric acid. Kelp decoction showed stronger potential in reducing TCA cycle intermediates and glycolysis intermediates than the other two groups, while the levels of branched chain amino acids were the lowest after licorice extracts were given. These results suggested that the effect of the mixed decoction on metabolism was closely associated with both kelp and licorice. The continuous administration of single decoction of kelp and the mixed decoction of licorice and kelp resulted in pathological abnormalities in kidney of SD rats. The mixed decoction of kelp and licorice distinctly perturbed sera molecules and hence system metabolism, which showed associated with those of kelp and licorice. Although the metabolic effect was associated with both kelp and licorice, the results suggested kelp contributed to it primarily.
