Objective To evaluate the efficacy of liposuction-curettage under negative pressure combined with Xiaozhiling injection for the treatment of axillary bromhidrosis.Methods The operative field was marked along the border of hair-bearing area of axilla with a distal margin of 0.5-1 cm.Subcutaneous tissue was removed by stroke movement under negative pressure after tumescent anesthesia.Subsequently,Xiaozhiling injection was injected into the subcutaneous space.All the patients were followed for at least 3 months,and therapeutic efficacy was evaluated quantitatively.Results A total of 72 patients (144 sides) with axillary bromhidrosis were treated with this method from March 2009 to May 2012,including 16 males and 56 females aged 14-41 years.All the patients experienced primary healing with no necrosis or hematoma formation within one week after the operation.The follow-up lasted 3 to 18 months (average: 8 months).Among the 144 sides,133 (92.4％) were cured,11 (7.6％) were improved,with the response rate being 100％.Postoperative scar is invisible,and patients were satisfied with the treatment outcomes.Conclusion The combined therapy is a simple and effective approach to the treatment of axillary bromhidrosis with a fast recovery and less complications.

OBJECTIVETo investigate the effect of paraquat (PQ) on reactive oxygen species (ROS) and neutrophil apoptosis and its possible signal transduction pathways.

METHODSCultured neutrophils were treated with different concentrations of PQ for 6-24 h. The apoptosis rate of neutrophils and ROS content were determined by flow cytometry. The exoressions of nuclear factor kappa B (NF-κB) and Caspase 3 were detected by Western blot. These parameters were checked again after NF-κB and Caspase 3 antagonist were applied.

RESULTSPQ could boost ROS generation and depress neutrophil apoptosis significantly. At the same time PQ could enhance the expression of NF-κB and inhibit the expression of Caspase 3. These effects could be reversed by ROS inhibitor diphenyleneiodonium (DPI) and NF-κB inhibitor pyrrolidinedithiocarbamate (PDTC).

CONCLUSIONPQ is a potent inducer of ROS and can inhibit neutrophil apoptosis by activating NF-κB and surpressing Caspase 3 activity.

OBJECTIVEWith functional magnetic resonance imaging (fMRI), cerebral function imaging of acupuncture and sham acupuncture at Taichong (LR 3) in patients with essential hypertension (EH) was observed to analyze central mechanism of Taichong (LR 3) to treat EH.

METHODSEighteen EH patients were divided into a twisting acupuncture group (10 cases) and a sham acupuncture group (8 cases), which were treated with twisting manipulation and sham acu- puncture at right Taichong (LR 3), respectively. The treatments were both given with 30-second manipulation and 30- second interval for totally 5 min. During the acupuncture, fMRI was adopted to scan the cerebral function imaging of EH patients on resting state, and the acquired data were analyzed with SPM2 module in Matlab software.

RESULTSAcupunc- ture at Taichong (LR 3) in EH patients mainly increased opposite-side oxygen consumption, which generally activated left anterior cingulated gyrus (BA 32), left inferior parietal lobule (BA 40), left inferior temporal gyrus (BA 19), left middle temporal gyrus (BA 37) and right anterior central gyrus (BA 6). The activated areas were related to motor, vision and cognition of emotion. Stimulation region of sham acupuncture mainly included right anterior cingulated gyrus (BA 24), left inferior parietal lobule (BA 40) and left inferior frontal gyrus (BA 7).

CONCLUSIONThe central mechanism of Tai- chong (LR 3) on antihypertensive effect and symptom improvement is not in thalamus and medulla that are traditionally believed to control blood pressure. Taichong (LR 3) could activate anterior cingulated gyrus to regulate parasympathetic nerve and lower blood pressure, and through anterior cingulated gyrus, the connection with the surrounding areas is strengthened to improve the cognitive impairment caused by long-term hypertension.

AIM: To analyze the clinical feature and treatment of endogenous endophthalmitis caused by liver abscess. METHODS: A total of 9 eyes (7 cases) with endogenous endophthalmitis caused by liver abscess in our hospital from 2005 to 2010 were analyzed retrospectively. Microorganism was cultivated with blood or vitreous in all patients.4 eyes were performed vitrectomy. 2 eyes were injected antibiotics in vitreous cavity. 3 eyes were only treated with antibiotics.RESULTS: Two cases (2 eyes) were diagnosed with endophthalmitis firstly, then found liver abscess; 4 eyes were with diabetes mellitus, and 1 eye with abnormal glucose tolerance. Cultivation of microorganism was positive in 6 eyes (67%), including Pneumonia cray-research, Candida albicans and Escherichia coli. 5 eyes had useful vision after treatment, 1 eye had light perception,3 eyes became blindness. CONCLUSION: As an ocular emergency, endogenous endophthalmitis caused by liver abscess can severely damage visual function. Timely consultation, early diagnosis, proper systemic and topical anti-infective and anti-inflammatory treatment are the most effective methods for controlling infection. Vitrectomy with intravitreal antibiotics plays an important role in preserving useful vision function in patients.

AIM: To evaluate the effects of the extract of Buddleja officinalis eye drops in basic tears secretory volume, tear film stability, expression of androgen receptors(AR) in castrated rats with dry eye, and to investigate the therapeutic effects of extract of Buddleja officinalis on dry eye caused by gonadal hormones level imbalance. METHODS:A total of 45 Wistar masculinity rats were divided at random into 9 groups, including normal group(A1,A2 and A3), model group(B1,B2 and B3), therapy group with extract of Buddleja officinalis eye drops(C1,C2 and C3). The "1" stood for being fed for 1 month, and "2" for 2 months, and "3" for 3 months. The dry eye model was established with orchiectomy on group B,C. Group C was treated with Buddleja officinalis extract eye drops for one month. All rats were checked with Schirmer Ⅰ test (SⅠt) and tear film break-up time (BUT). Expression of AR was analyzed by flow cytometer(FCM). RESULTS:The SⅠt value of group C was significantly higher than that of group B (P<0.01) and the BUT value of group C was significantly longer than that of group B (P<0.01), which indicated the eye drop could significantly keep basic tears secretory volume and tear film stability. And the expression of AR of group C was much higher than that of group B,which showed that available composition of the eye drops maybe display androgen-like activity.CONCLUSION:The main components of extract of Buddleja officinalis is the flavonoids which could significantly inhibit happening of dry eye of rat after androgen level lowered. Its mechanism is like androgen's and it could display androgen-like activity to keep basic tears secretory volume and tear film stability.
