After 4 months of treatment, the residual urine and the time to reduce the residual urine were compared.ResultsThere was no differences in deducing the residual urine and the time to reduce the residual urine between the two groups.ConclusionAlfuzosin has limited effect in reducing the residual urine in bladder management.

OBJECTIVETo sum up the clinical experience in the management of benign prostatic hyperplasia (BPH) with the prostate weighing over 80 ml by transurethral resection of the prostate (TURP) combined with 2 μm continuous-wave laser vaporesection (LVR).

METHODSWe retrospectively analyzed the clinical effects of TURP combined with 2 μm LVR in the treatment of 46 cases of BPH with the prostate volume > 80 ml.

RESULTSAll the operations were successfully accomplished. The operation time and intraoperative blood loss were (112.0 ± 20.0) min (range 86-176 min) and (77.9 ± 25.9) ml (range 50-200 ml), respectively. The catheters were withdrawn at 7 days after surgery. Transient urinary incontinence occurred in 6 cases and secondary hemorrhage was found in 2 postoperatively. Six-month follow-up revealed no urethral stricture or other complications. Compared with the baseline, the international prostate symptom score (IPSS) was significantly decreased at 6 months after operation (26.3 ± 1.8 vs 11.6 ± 1.7, P <0.05), and so were the quality of life (QOL) score (5.3 ± 0.7 vs 1.3 ± 1.1, P <0.05) and post-void residual urine (PVR) ([115.5 ± 55.6] ml vs [19.9 ± 11.6] ml, P <0.05). However, the maximum urinary flow rate (Qmax) was remarkably increased from (4.1 ± 2.6) ml/s to (16.2 ± 1.7) ml/s (P <0.05).

CONCLUSIONTURP combined with 2 μm LVR is safe and effective for the treatment of BPH with the prostate volume >80 ml.

Abstract: Objective To explore and analyze the diagnostic value of multicolor melting curve analysis (MMCA) for the resistance of five anti-tuberculosis drugs, so as to clarify the clinical value of MMCA in detecting drug resistance of Mycobacterium tuberculosis. Methods From April 2021 to May 2022, 200 patients with positive Mycobacterium tuberculosis admitted to the Fourth People's Hospital of Qinghai Province were selected as research objects, and sputum specimens were taken from the patients. Traditional Mycobacterium tuberculosis drug sensitivity test (modified Löwenstein-Jensen medium method) and MMCA analysis were respectively given to detect the resistance of five anti-tuberculosis drugs, including isoniazid, ethambutol, streptomycin, rifampicin and isoniazid, respectively. Those samples with inconsistent results between the two diagnosis methods were subjected to gene sequencing verification, and the diagnosis efficiency of MMCA for the five anti-tuberculosis drugs was compared. Results Using Mycobacterium tuberculosis drug sensitivity as the gold standard for drug resistance diagnosis, the sensitivity of MMCA for detecting drug resistance of rifampicin, ethambutol, streptomycin, isoniazid and levofloxacin were 95.83% (46/48), 93.75% (15/16), 100.00% (15/15), 100.00% (20/20) and 70.00% (7/10), respectively, with statistical differences between groups (P<0.05). There were no statistically significant differences in the specificity, positive predictive value, negative predictive value and accuracy of MMCA for the five anti-tuberculosis drugs (P>0.05). For the 8 samples with inconsistent results between MMCA and modified Löwenstein-Jensen medium method, gene sequencing was performed and compared with the results of gene sequencing. After comparison with gene sequencing results, it was found that the coincidence rate of MMCA and gene sequencing results was 75.00% (6/8). Conclusions In the detection of drug-resistant mutations in TB patients, multi-color probe fusion curve analysis has high diagnostic efficacy for first-line anti-tuberculosis drugs, but is not sensitive to second-line anti-tuberculosis drug levofloxacin. Therefore, for the detection of first-line anti-tuberculosis drugs, MMCA has a good clinical application prospect.

OBJECTIVETo investigate the effect of DNA methyltransferases 1 (DNMT-1) inhibition on the ACC-M cells in vitro and in vivo and discuss the role of DNMT-1 in the development, invasion and metastasis of salivary adenoid cystic carcinoma (SACC).

METHODSACC-M cells of stable DNMT-1 inhibition were established in a previous research. In vitro, the growth and invasion of ACC-M cells which stably inhibited DNMT-1 were detected and analyzed by methyl thiazolyl tetrazolium (MTT) growth curve, flow cytometry, plating efficiency and invasion assay. In vivo, the growth and metastasis of ACC-M cells which persistently inhibited DNMT-1 were observed and analyzed by subcutaneous injection and tail vein injection into the nude mice.

RESULTSIn vitro, the doubling time [(34.7 +/- 2.1) h], S phase fraction [(17.4 +/- 1.7)%], plating efficiency [(43.0 +/- 1.3)%] of ACC-M cells was significantly different from those of blank [(26.2 +/- 3.1) h, (31.5 +/- 2.0)%, (71.0 +/- 4.7)%], empty load control [(28.4 +/- 3.9) h, (39.0 +/- 2.0)%, (66.0 +/- 5.2)%], P < 0.05, and the invasion ability was not significantly different among these groups (P > 0.05). In vivo, the subcutaneous tumor forming rate (6/10), volume [(2.18 +/- 0.83) mm(3)], weight [(0.0156 +/- 0.0046) g] of ACC-M cells was also significantly lower than that of blank [10/10, (155.44 +/- 1.67) mm(3), (0.0724 +/- 0.0157) g], empty load control [10/10, (147.46 +/- 1.73) mm(3), (0.0729 +/- 0.0177) g], P < 0.05, but the rate of lung metastasis was not significantly different among these groups (P > 0.05), and the masses (2.0 +/- 0.5), diameter (70.0 +/- 20.3) microm of ACC-M cells was significantly lower than that of blank [(28.0 +/- 5.5), (195 +/- 25.4) microm], empty load control [(27.0 +/- 4.5), (190.0 +/- 19.9) microm], P < 0.05.

CONCLUSIONSInhibition of DNMT-1 is able to inhibit the proliferation and metastasis of ACC-M cells in vitro and in vivo.

AIMTo investigate whether mitochondrial calcium uniporter participates in the cardioprotection of tumor necrosis factor alpha (TNFalpha) pretreatment in isolated rat hearts subjected to ischemia/reperfusion.

METHODSIsolated perfused rat hearts were subjected to 30 min regional ischemia (occlusion of left anterior descending artery) and 120 min reperfusion. The infarct size, coronary flow (CF) and lactate dehydrogenase (LDH) release during reperfusion were measured. The mitochondria of the heart were isolated and suspended in the swelling buffer for measurement of absorbance at 520 nm.

RESULTSPretreatment with TNFa at 10 U/ml for 7 min followed by 10 min washout reduced the infarct size and LDH release, and improved the recovery of CF during reperfusion. Administration of spermine (20 micromol/L), an opener of mitochondrial calcium uniporter, for 10 min during early reperfusion attenuated the reduction of infarct size and LDH release, and improvement of CF induced by TNFalpha. In isolated mitochondria of the heart pretreated with TNFalpha, the absorbance at 520 nm decreased less than that of mitochondria without TNFalpha pretreatment. Administration of spermine (50 micromol/L) attenuated the change of the absorbance induced by TNFalpha.

CONCLUSIONThe findings indicate that TNFalpha protects myocardium against ischemia/reperfusion injury via inhibiting mitochondrial calcium uniporter opening as well as mitochondrial permeability transition pore opening.

OBJECTIVETo investigate the application of auditory brainstem response (ABR) and 40 Hz auditory event related potential (40 Hz AERP) to the diagnosis of occupational noise-induced hearing impairment and to provide the evidence for diagnosis of occupational deafness.

METHODSPure tone audiometry, ABR and 40 Hz AERP were performed in 54 workers occupationally exposed to noise. The thresholds of higher frequency band, 3 kHz and 4 kHz were compared with the threshold of ABR. The thresholds of auditory frequency ban and 0.5 kHz were compared with the threshold of 40 Hz AERP.

RESULTSA better correlation was found between thresholds of ABR and higher frequency pure tone audiometry. There was a significant difference of thresholds between 40 kHz AERP and pure tone audiometry. The correction values of thresholds between 40 kHz AERP and pure tone audiometry in the light noise-induced hearing impairment group and the moderate noise-induced hearing impairment group were (16.43 ± 1.08) and (11.80 ± 1.12) dBn HL, respectively.

CONCLUSIONIn diagnosis of occupational noise-induced hearing impairment, the threshold of ABR can be used to estimate the hearing threshold of pure noise higher frequency. Because there is the significant difference of the thresholds between pure tone audiometry and 40 Hz AERP, the response threshold can not be served as the audiometry threshold, and the behavioral hearing thresholds can only be obtained by adjusting the response threshold with respective correction value.
