Objective To assess the effects on volume of uterine and the dominant fibroid by a re-new radiofrequency ablation ( RFA ) on uterine myomas and disemboweling them from uterine after RFA . Methods Three hundred and eight -three patients were treated by RFA and followed up at 1, 3, 6 and 12 months,165 of them by usual RFA , 163 by improved RFA.To them which myomas diameters were >5cm, 55 cases were added by disemboweling the myomas out of the body after one month of improved RFA .But 66 were not disemboweled.The pre-and postoperative uterine and myoma volumes were measured by 3D ul-trasonography .Results The volume of uterine and the dominant fibroid were reduced in usual and im-proved RFA groups , especially in improved group ,but the difference was no significantly ( P >0.05 ) .In the groups of which myomas diameters were >5cm , the median reduction rates of uterine and myoma vol-ume was more significantly in disemboweling group than un -disemboweling one after 3 and 6 months ( P <0.05 , P <0.01 ) .The overall effective rates were 90.90%,93.25%,100%and92.42%respectively in u-sual and improved RFA groups( P >0.05),and in disemboweling and un -disemboweling groups ( P >0.05).But the obvious effective rates have significant difference in disemboweling (81.82%)and un-dis-embowelin(41.94%)group ( P <0.01).Conclusion Disemboweling myomas from uterine after RFA can increase the clinical effects significantly .

ObjectiveTo assess the energy expenditure status in critically ill children on mechanical ventilation.MethodsFifty critically ill children on mechanical ventilation were enrolled in this study.Resting energy expenditure (REE) on days 1,3,5,and 7 were measured.The predictive REE was calculated for each subject using age-appropriate equations (Schofield-HTWT).ResultsREE on day 1 and Schofield-HTWT equation predictive REE were (96.80 ± 42.63 ) and ( 110.67 ± 38.35 ) kJ/d,respectively.REE on days 1,3,5,and 7 were (100.53 ±50.24),(113.80 ±49.19),(117.99 ±50.57),and (115.05±50.18) kJ/d,respectively (F =1.267,P =0.292).The REE of day 1 in children with congenital heart disease (CHD) and without CHD was (75.66 ± 31.23 ) and ( 113.40 ± 28.40) kJ/d,respectively ( F =10.423,P =0.002).ConclusionsThe hypometabolic response is apparent in critically ill children with mechanical ventilation,and the energy expenditure shows no time-specific change within the first week.The energy expenditure in children with CHD is lower than those without CHD.

Objective To investigate the clinical manifestations of the febrile neutropenia cancer children,explore the relationship between the clinical data and sepsis.Methods A prospective observation study was employed,and 66 cancer children complicated with febrile and neutropenia after chemotherapy were enrolled.Sixty-six cases were divided into two groups:septic group ( n =26 ) and non-septic group ( n =40).Clinical and laboratory data were collected and compared.Results Body temperature,neutropenia duration,absolute neutrophic count ( ANC ),C-reactive protein ( CRP ),procalcitonin (PCT) and culture positive rate showed statistically differences between the septic and non-septic groups ( P ＜ 0.05 ).Body temperature ＞40 ℃,ANC ＜ 0.1 × 109/L,increases of serum CRP and PCT levels and positive culture were correlated with sepsis.Body temperature ＜ 39 ℃,neutropenia duration ＜ 5 ds,ANC ＞ 0.5 × 109/L were less correlated with sepsis.Conclusion High initial temperature,long duration of neutropenia,severely reduced ANC,increases of CRP and PCT,and culture-positive are correlated with sepsis in cancer children.

Objective To investigate the changes of plasma activated protein C(APC)in the pediatric leukemia patients with acute lung injury(ALI),and the relationship with the outcome.Methods During the study period(from Jan to Dec 2009),17 pediatric leukemia patients with ALI were selected.They were divided into neutropenic(n =10)and non-neutropenic(n =7)group.We collected the basic data including the age,gender,stage of chemotherapy,pediatric critical illness score,mechanical ventilation time,ICU time.The blood gas and plasma APC levels were detected on day 1 and day 4 of ALI onset.Results Compared with the non-neutropenic group,the neutropenic group had a significantly longer mechanical ventilation time [(16.60 ± 1 0.83)d vs(3.79 ± 4.08)d,P =0.009 6],lower PaO2 level on day l[(54.90 ± 17.05)mm Hg vs (92.70 ± 27.53)mm Hg,P =0.009 7],and lower APC level on day 4[(193.06 ± 63.19)pg/mlvs(286.28 ±25.12)pg/ml,P =0.007 7].Conclusion The APC generation is severely impaired in the neutropenic group,especially in those who died.The lower APC level is,the longer is the mechanical ventilation time,the worse is oxygenation,the poorer is the prognosis.APC replacement therapy may be promising in these patients.

Aim To study the change of mutant pre- vention concentration (MPC) in carbapenem-resistant Acinetobacter baumannii (CRAB) treated with moxi- floxacin ( MFX ) and/ or cefoperazone/ sulbactam (CFS) in vitro, and provide a theoretical support for preventing the bacterial resistance. Methods To cal- culate the fractional inhibitory concentration (FIC) in- dex, the minimum inhibitory concentration (MIC) of 20 clinical isolates of CRAB treated with MFX and/ or CFS was determined by checkerboard microdilution as- say. In addition, to calculate the selection index (SI), the MPC of 20 clinical isolates of CRAB treated with MFX and/ or CFS was determined by agar plate di- lution assay. Results Our study showed that there was synergistic/ addictive action, rather than antago- nism action against clinical isolates of CRAB when treated with MFX + CFS. The SI of the 20 isolates trea- ted with MFX or CFS alone was 4 ~128 and 8 ~64 re- spectively, but reduced to 1 ~8 and 4 ~16 when trea- ted with MFX + CFS, which decreased by 2 ~16 and 2 ~4 times respectively compared with the single treat- ment. Conclusion These results suggest that the combination treatment of MFX + CFS against clinical isolates of CRAB might lower the MPC of the isolates treated with MFX/ CFS alone, narrow the mutant selec- tion window, and prevent the generation of drug - re- sistant mutants.

OBJECTIVETo evaluate the therapeutic effect of pedicled muscular flaps combined with partial thoracotomy for treatment of pythorax-resulted wounds and defects.

METHODS35 cases with pythorax-resulted refractory infected wound and dead space, were retrospectively analyzed. The wound and dead space were eliminated with pedicled muscular flaps, including latissimus dorsi muscular flaps and serratus anterior muscle flaps in 21 patients, pectoralis major muscle flaps with rectus muscle flaps in 8 patients, latissimus dorsi muscul flaps and vertical rectus muscle flaps in other 6 patients.

RESULTS34 flaps survived completely except for 1 verticle rectus muscular flap with partial necrosis at distal end. Primary healing was achieved in 29 cases. The other 6 cases were discharged with drainage. Among the 6 cases, 3 cases healed spontaneously, 2 cases underwent reoperation, 1 case need long-term drainage in the fistula.

CONCLUSIONPedicled muscular flap, combined with partial thoracotomy can effectively treat refractory wound and dead space resulted by pythorax.

Objective To study the alveolar macrophages (AM) activation in neutropenic ARDS in children with hematologic malignancy. Methods Thirteen patients of ARDS were prospectively enrolled into the study and divided into two groups,neutropenic (5 cases) and nonneutropenic (8 cases). Bronchoalveolar lavage fluid (BALF) samples were analyzed for differential and total cell counts, and alveolar activation marker expression (HLA-DR) was determined. Results In neutropenic patients,the BALF total cell count and the macrophage absolute count were significantly lower compared to those in nonneutropenic group ((62. 6 ±9. 6)/μl vs ( 124. 0 ± 6. 7)/μl,P ＜ 0. 01 and (40. 8 ±4. 3)/μl vs (67. 6 ± 10. 7)/μl,P ＜ 0. 01,respectively). As compared with the nonneutropenic group, the percentage of AM in neutropenic patients was significantly higher (65.9% ±9. 0% vs 54. 6% ± 8. 7% ,P ＜0. 05) ,the mean percentage of AM HLA-DR expression was significantly lower (35. 3% ± 5.8% vs 62. 2% ± 5. 8%, P ＜ 0. 01 ). Conclusion These results suggest an alveolar hypocellularity and a deactivation of AM in neutropenic ARDS in children with hematologic malignancy.

Objective To grasp the current situation and trend of health personnel development in public TCM hospitals through the analysis of health personnel statistics data of public TCM hospitals in China; To provide decision-making references for management departments. Methods Data were from the National Health and Family Planning Commission Statistical Information Center. This article analyzed staff number, the average speed of development, the average annual growth rate, health staff age, academic qualifications and job titles and other indicators of TCM public hospitals during 2010-2015. Results From 2010 to 2015, there was an annual increasing tendency of the number of TCM health personnel, and the average annual growth rate was 5.9％, but the growth of the percentage of the TCM health personnel to the total health personnel was only 0.3％. In 2015, the proportion of TCM health personnel was less than 50％; the doctor-to-nurse ratio was 1:1.18; the educational level of postgraduate and undergraduate were 14.0％ and 48.0％ respectively, less than the average level of national hospitals. Conclusion From 2010 to 2015, there is an increasing tendency of the TCM health personnel of public TCM hospitals, but the proportion of TCM health personnel is low. The doctor-to-nurse ratio is reasonable gradually, but there is still a gap compared with the average level of the national hospitals. The average age of technical health personnel tends to be younger. The proportion of high educational level health personnel is increasing, but the proportion of senior technical position is reduced. The management departments should take appropriate measures to promote the rational allocation of human resources and development of TCM hospitals.

Objective: To investigate the pharmacodynamics of modified Xiaochaihutang granules (MXG) and its active ingredients group (AIG) on gastric ulcer in order to provide scientific basis for the clinical effect and lay foundation for the development of related hospital preparations.Methods: Gastric ulcer models induced by pyloric ligation,acetic acid and ethanol were applied to observe the curative effects of MXG and its AIG, and the effects of MXG and its AIG on gastric secretion, gastric acid content, pepsin activity, superoxide dismutase (SOD) and malondialdehyde(MDA) contents were also studied.Results: Compared to the model control group,MXG and AIG could significantly reduce the ulcer index(P<0.01), total acidity(P<0.01),and pepsin activity (P<0.05 or 0.01), increase the SOD activity (P<0.05)and inhibit the increase of lipid peroxide MDA.Conclusion: MXG and AIG show better control effects on acute and chronic gastric ulcer, and the effects are related to reducing the activity of pepsin, increasing the SOD activity, inhibiting the increase of lipid peroxide MDA and so on.
