OBJECTIVEGas chromatography (GC) was used to investigate the cellular fatty acid (CFA) composition of 141 Acinetobacter baumannii and 32 A. calcoaceticus isolates from different locations in China and to find chemical markers to differentiate these two closely related bacteria.
METHODSWhole cell fatty acid methyl esters (FAMEs) were obtained by saponification, methylation, and extraction for GC analysis, followed by a standardized Microbial Identification System (MIS) analysis.
RESULTSAll A. baumannii and A. calcoaceticus strains contained some major fatty acids, namely, 18:1 ω9c, 16:0, Sum In Feature 3, 12:0, 17:1ω8c, 3-OH-12:0, 17:0, Sum In Feature 2, 2-OH-12:0, and 18:0 compounds. Although most of the total CFAs are similar between A. baumannii and A. calcoaceticus strains, the ratios of two pairs of CFAs, i.e., Sum In Feature 3/18:1 ω9c versus 16:0/18:1 ω9c and Sum In Feature 3/18:1 ω9c versus unknown 12.484/18:1 ω9c fatty acids, could differentiate these two closely related bacteria. A. baumannii could be easily classified into two subgroups by plotting some ratios such as Sum In Feature 3/16:0 versus 17:0 and Sum In Feature 3/2-OH-12:0 versus 17:0 fatty acids.
CONCLUSIONThe ratios of some CFAs could be used as chemical markers to distinguish A. baumannii from A. calcoaceticus.

OBJECTIVETo study the bone state with ultimate stress by examining biomechanical distribution of upper femur in Chinese, in order to accumulate more experiences for clinical work.
METHODSTotally 60 Chinese femurs from fresh cadavers were randomly divided into two groups. All the femurs were cleaned, and the body age ranged from 36 to 72 years old, averaged 56.4 years, including 41 from males, and 19 from females. These two groups underwent mechanical stress and bending stress tests. Special mechanical laboratory and machines were used to get the information. Results about the loading value at each testing point under stress were collected.
RESULTSThe four faces of the upper femur suffered different stress under external forces. The bone on upper femur can tolerate more mechanical stress than bending stress. Medial and lateral region of the femur neck and the rear side of the small tuberosity section were themain position enduring the vertical stress. The rear position of the base femur neck and the small tuberosity section were the main regions enduring the bending stress. Those main positions had strong cancellous bones. The intertrochanteric fracture fixation and artificial femoral stems were designed depending on this biomechanical basis.
CONCLUSIONAccording to our experiment result, doctors need to chose more effective fixations for upper femur fracture, and femoral stems for the patients. More information should be collected by further researches.

OBJECTIVETo investigate the effect of heme oxygenase-1 (HO-1) expression on cell growth and apoptosis in imatinib resistant chronic myeloid leukemia (CML) cells (K562/A02-IM), and explore the relationship between HO-1 gene and CML.
METHODSThe expression of HO-1 in 20 drug-resistant CML patients was detected by RT-PCR. Different concentrations of hemin were used to induce HO-1 expression of K562/A02-IM, HO-1 expression at different time was detected by RT-PCR and Western blot analysis. Cell apoptosis was detected by Annexin V/PI staining, and MTT assay was used to detect viability of K562/A02-IM cells after induction or inhibition of HO-1 gene by hemin and zinc protoporphyrin (ZPP).
RESULTSRT-PCR showed that HO-1 was expressed in the bone marrow mononuclear cells (BMMNCs). When treated with hemin at different concentrations (0, 10, 20, 40 µmol/L) for 16 h, the expression of HO-1 in K562/A02-IM was increased in a dose-dependent manner, and peaked at 20 µmol/L of hemin for 16 h. The apoptosis rates were (17.61 ± 0.01)%, (12.13 ± 0.11)%, (7.94 ± 0.03)% and (4.62 ± 0.15)% at 0,10, 20 and 40 µmol/L of hemin respectively for 16 h and were (14.7 ± 0.05)%, (8.1 ± 0.07)% and (16.3 ± 0.13)% at 20 µmol/L of hemin treatment for 8,16, and 24 h respectively. Hemin induced apoptosis of K562/A02-IM cells in a dose-dependent manner. The expression of HO-1 was induced in K562/A02-IM cells in a dose-dependent manner, and the survival of K562/A02-IM cells was significantly increased as compared to that of control group. When HO-1 was inhibited by ZPP, the cells survival was sharply decreased compared to that of the control group (P < 0.05).
CONCLUSIONHO-1 was expressed in the BMMNCs. It is a kind of molecules whose expression can be induced and can promote the growth of drug-resistant cells. Inhibition of HO-1 expression probably be used for the treatment of drug-resistant CML.

OBJECTIVETo verify efficacy of moxibustion apparatus on pulmonary tuberculosis (PT) and explore adjuvant treatment method for PT.
METHODSOne hundred cases of PT were randomly divided into a moxibustion group and a routine treatment group, 50 cases in each one. The regular antituberculous therapy (2HRZE/4HRE) was applied in both groups. In addition, the moxibustion apparatus was used at Bailao (EX-HN 15), Feishu (BL 13), Gaohuang (BL 43), Qihai (CV 6), Zhongfu (LU 1), Danzhong (CV 17), Guanyuan (CV 4), Zusanli (ST 36) and so on in the moxibustion group. The change of lesion area in chest radiography, degradation rate of bacte rium in the sputum, T-lymphocyte subsets and natural kill (NK) cells were observed before and after treatment in two groups.
RESULTSAfter the treatment for 3 months, there were 45 cases (90.0%) in the moxibustion group with more than 45% of focal absorption in chest radiography, which was obviously higher than 72.0% (36/50) in the routine treatment group (P < 0.01). The degradation rate of bacterium in the sputum in the moxibustion group was higher than that in the routine treatment group [82.0% (41/50) vs 60.0% (30/50), P < 0.01]. The CD3+, CD4+/CD8+ ratio of T-lymphocyte subsets and NK cells in the moxibustion group were significantly higher than those in the routine treatment group (P < 0.05, P < 0.01).
CONCLUSIONOn the basis of regular antituberculous therapy, moxibustion apparatus could significantly improve clinical effect, promote focal absorption and boost immunity, which is considered as an adjuvant treatment for PT.

OBJECTIVEAccording to the information obtained from the revision of total hip arthroplasty, the situations of the artificial femoral stem under physiological stress were analyzed preliminarily. In order to accumulate clinical experience, the discussions about how to enlongate the life of artifical joints were performed.
METHODSFifty-three patients required revision operations were selected, including 28 males and 25 females,with an average age of 74.66 years old (61 to 84 years old). The average life of artificial joints was 18.24 years (3 to 27 years). The initial weightbearing was started 11 days (5 to 16 days) after the first operation. The main reasons for the revision were the spontaneous loosening and trauma. Based on imaging and surgical findings, as well as the histological pathology, the situations of the stems in human bodies were determined.
RESULTSFemoral prosthesis would sink under physiological stress. The design of femoral stems, motion of patients', and bone growth determined the secondary stability. Straight stems were helpful for physiological subsidence of prosthesis, achieving the stability with close bone-implant contact by bone growth,which allowed the patient to do early landing exercise. The collared prosthesis and prosthesis combined with internal fixation limited the subsidence of femoral stems. Their stability depends on the time of initial placement and the bone growth for supporting. Delaying the inital weightbearing was suggested for patients with these protheses.
CONCLUSIONAccording to the actual situation of the patients, the appropriate chosen of femoral stems and time to perform the weightbearing can extend the life of the femoral prosthesis.
