OBJECTIVETo compare the clinical efficacy differences between medicinal vesiculation combined with quick cupping at Shenque (CV 8) and regular medication for allergic rhinitis with syndrome of yang deficiency.

METHODSEighty-two cases were randomly divided into an observation group (42 cases) and a control group (40 cases). The observation group was treated with medicinal vesiculation combined with quick cupping at Shenque (CV 8). The medicinal vesiculation was applied at Feishu (BL 13), Gaohuang (BL 43), Fengmen (BL 12), Mingmen (GV 4) on the dog days in the summer, one treatment on the 1st dog-day, 2nd dog-day and last dog-day respectively with an interval of 10 days between two treatments. Three treatments were taken as one course, and totally one course was given. The quick cupping was applied at Shenque (CV 8), once a day, ten treatments were taken as one course, and totally three courses was given. The control group was treated with oral administration of loratadine and nasal spray of budesonide. The loratadine was given 10 mg per time, once a day for continuous 14 days; budesonide was given once a day, ten treatments were taken as one course, and totally three courses was given. The clinical efficacy in two groups after treatment was observed, and the contents of immune globulin E (IgE), interleukin-4 (IL-4), interleukin-5 (IL-5) and tumor necrosis factor-α (TNF-α) in peripheral serum were measured before and after the treatments.

RESULTSOf all the 82 patients, 79 cases completed the treatment, and 1 patient in the observation group and 2 patients in the control group dropped out. The effective rate was 87.8% (36/41) in the observation group, which was superior to 78.9% (30/38) in the control group (P<0.05). After treatment, both groups effectively reduced the contents of IgE, IL-4, IL-5 and TNF-α, and the observation group had superior effect on reducing IgE and IL-4 to the control group (P<0.05).

CONCLUSIONThe medicinal vesiculation combined with quick cupping at Shenque (CV 8) have better effect for allergic rhinitis with syndrome of yang deficiency than oral administration of loratadine and nasal spray of budesonide.

AIMTo analyse the impurities of gatifloxacin.

METHODSThe impurity of gatifloxacin were analysized and determinated by RP-HPLC/electrospray ionization mass spectrometry with a Zorbax SB-C18(4.6 mm x 150 mm ID, 5 microns). The mobile phase was 3% acetic acid/acetonitrile-3% acetic acid/water (15:85). The two compounds were synthesized: 1-cyclopropyl-6-fluoro-1, 4-dihydro-8-methoxy-7-(1-piperazinyl)-4-oxo-3-quinolinecarboxylic acid (DMP) and 1-cyclopropyl-6-fluoro-1, 4-dihydro-8-hydro-7-(3-methy-1-piperazinyl)-4-oxo-3-quinolinecarboxylic acid (DMO). Their liquid chromatogram, UV, MS were compared with those of the impurity of gatifloxacin.

RESULTSThe mass of the impurity was 14 less than that of gatifloxacin. It means the impurity was CH2 less than gatifloxacin. The tR (HPLC), UV and MS of DMP were the same as those of the impurity of gatifloxacin.

CONCLUSIONBased on the tR (HPLC), UV and MS, the impurity of gatifloxacin is confirmed as DMP.

OBJECTIVETo evaluate the effect of meatoplasty with the pedicle flap in the treatment of meatal stenosis secondary to chronic balanitis.

METHODSWe retrospectively analyzed 32 cases of meatal stenosis secondary to chronic balanitis treated by meato- plasty with the pedicle flap. All the patients had a history of chronic balanitis and had received meatal dilatation or simple ventral mea- totomy without significant effect. Their mean maximum urinary flow rate (Qmax) was (4.3 ± 2.4) ml/s. During the operation, A "/\"-shaped incision was made in the healthy epidermis and a flap was harvested from the frenulum. After complete removal of the scar, the flap was placed into the urethral wall, followed by reconstruction of the external urethral orifice.

RESULTSThe patients were fol- lowed up for 6 to 30 months, which revealed smooth urination in all the patients with Qmax of (26.7 ± 4.5) ml/s and normal erectile function and uresiesthesis.

CONCLUSIONWith little invasiveness and few complications, meatoplasty with the pedicle flap is an ideal surgical method for the treatment of meatal stenosis secondary to chronic balanitis. However, there might be some change in the normal appearance of the balanus postoperatively, and its long-term effect needs further observation.

OBJECTIVE: To summarize the method and experience of direct observation of the effect of mitral valvuloplasty on beating heart. METHODS: Twelve patients with mitral regurgitation underwent mitral valvuloplasty. When the heart was beating slowly before releasing the aorta, the morphology and function of the mitral valve were evaluated by direct observation. If the results were unsatisfactory, further techniques were used to reach the goal. RESULTS: During the operation 2 patients needed further techniques to make the mitral valve work well. No operative death and only 1 complication (low cardiac output syndrome) occurred. After 1 month follow-up later, mild regurgitation was found in 5 patients, moderate regurgitation in 1 and no obvious regurgitation in 6. CONCLUSION Evaluating the effect of mitral valvuloplasty by direct observation on beating heart is practicable.
