Objective:To investigate the efficacy of modified urethral dilatation in the treatment of female bladder neck obstruction.Methods:The clinical data of 33 female patients with bladder neck obstruction who underwent modified urethral dilatation in the Third People's Hospital of Qingdao from March 2015 to March 2020 were retrospectively analyzed. Before treatment, physical examination, routine urine examination, International Prostate Symptom Score, ultrasound examination, urodynamic examination and cystourethroscopy were performed to confirm the diagnosis. All patients were treated with α-blocker for more than 3 months, but obvious effect was not obtained. Under local anesthesia, they underwent modified urethral dilatation. After 3 months of treatment, International Prostate Symptom Score and urodynamic examination were performed to determine residual urine volume, the maximum urinary flow rate, and detrusor pressure at the maximum urinary flow rate. The curative effects of modified urethral dilatation were evaluated.Results:After modified urethral dilatation, dysuria was obviously alleviated in 25 patients. Eight patients who had no obvious improvement in dysuria were scheduled to undergo transurethral bladder neck incision. International Prostate Symptom Score after treatment was significantly lower than that before treatment [(15.18 ± 6.19) vs. (24.86 ± 7.26), t = 3.782, P < 0.001). Residual urine volume after treatment was significantly smaller than that before treatment [(53.69 ± 48.35) mL vs. (181.45 ± 92.15) mL, t = 15.328, P < 0.001]. The maximum urinary flow rate after treatment was significantly higher than that before treatment [(16.21 ± 4.22) mL/s vs. (7.91 ± 1.69) mL/s], t = 6.358, P < 0.001]. Detrusor pressure at the maximum urinary flow rate after treatment was significantly lower than that before treatment [(27.38 ± 5.13) cmH 2O vs. (57.15 ± 8.43) cmH 2O, t = 9.584, P < 0.001]. Conclusion:Modified urethral dilatation is an effective treatment method of female bladder neck obstruction. It can be used as a supplement for surgical treatment.

At present, Chinese medical field faces with an important problem of how to correctly handle the relationship between medical and scientific research. Academician Li Lianda advocates doctors doing scientific research under the premise of putting the medical work first. He points out that there are many problems in the process of doctors doing scientific research at present such as paying more attention to scientific research than medical care, excessively promoting building scientific research hospital, only paying attention to training scientific talents, research direction be flashy without substance, the medical evaluation system should be improved and so on. Medical, scientific research and teaching are inseparable because improving medical standards depends on scientific research and personnel training. But not all doctors need to take into account of medical treatment, scientific research and teaching in the same degree while not all hospitals need to turn into three-in-one hospital, scientific research hospital or teaching hospital. It must be treated differently according to the actual situation.

Objective To observe the effect of comprehensive rehabilitation based on motor control on sensory-ataxic acute Guillain-Barre syndrome. Methods A patient with sensory-ataxic acute Guillain-Barre syndrome was treated with kinesitherapy based on motor control,included proprioceptive neuromuscular facilitation, coordination training, functional training, balance training, as well as sensory stimulation on the end of arms and legs, recumbent cross trainer therapy and cycle therapy for 2 months. Results After treatment, the score of International Cooperative Ataxia Rating Scale (ICARS) decreased 36 points, activities of daily living increased 9 points, Berg Balance Scale increased 9 points, and modified Barthel Index increased 50 points. Conclusion The comprehensive rehabilitation based on motor control is effective on this patient, but more cases and systematic curative effect evaluation are needed.

Objective: The method of loop-mediated isothermal amplification (LAMP) was employed to detect and identify Cordyceps sinensis rapidly. Methods: Specific LAMP primers were designed according to the CS2 serine protease (csp2) gene of Cordyceps sinensis. C. sinensis DNA was extracted using CTAB method. The reaction conditions of LAMP were optimized. Specificity of LAMP reaction was validated by six different strains and using restriction enzyme Taq1 digested the LAMP products. Sensitivity of LAMP was tested with diluted C. sinensis solution with 10-fold gradient. LAMP products were shown by gel electrophoresis or adding SYBR Green I. Results: The method of LAMP for detecting C. sinensis was effective and specific. The detection limit of LAMP assay was up to 6 pg/mL. Conclusion: LAMP protocol is a promising method for the identification and detection of C. sinensis and Chinese materia medica as well.

Objective To investigate the therapeutic effect of minimally invasive percutaneous nephrostolithotomy (mPCNL) in treatment of kidney calculi and the influence of renal function.Methods According to the operation method,70 patients with kidney calculi were divided into mPCNL group (38 patients) and percutaneous nephrostolithotomy (PCNL) group (32 patients).The curative effect,serum creatinine (SCr) and blood urea nitrogen (BUN) postoperative 1 month were compared.Results The patients in two groups were successfully for broken calculi.The operation time of stag-horn calculi,retinitis simplex kidney pelvis calculi and kidney calices multiple calculi in PCNL group were significantly shorter than those in mPCNL group [(89.13 ± 13.36) min vs.(112.32 ± 12.41) min,(65.28 ±9.76) min vs.(78.84 ± 12.03) min,(98.97 ± 11.84) min vs.(112.64 ± 10.87) min,P ＜ 0.05].The first stage clearance rate of retinitis simplex kidney pelvis calculi in PCNL group was significantly higher than that in mPCNL group [88.89％(8/9) vs.57.14％(8/14),P ＜ 0.05].But the clearance rate of kidney calices multiple calculi in PCNL group was significantly lower than that in mPCNL group [58.33％(7/12) vs.86.67％(13/15),P＜0.05].The first stage clearance rate of stag-horn calculi in two groups had no significant difference [63.64％(7/11) vs.66.67％ (6/9),P ＞ 0.05].The patients in two groups had no serious complication.The rate of fever after operation in two groups had no significant difference [15.63％ (5/32) vs.10.53％ (4/38),P ＞ 0.05].The level of SCr and BUN in the patients combined with kidney insufficiency in two groups were decreased slightly (P ＞ 0.05).The improvement rate of renal function in two groups had no significant difference (P ＞0.05).Conclusions mPCNL and standard channel PCNL in treatment of kidney calculi can achieve a good first stage clearance rate,and the incidence rate of postoperative complication is lower.mPCNL and standard channel PCNL have no obviously influence on early stage renal function.The operation time of mPCNL is generally longer,but the therapeutic effect of kidney calices multiple calculi is better than standard channel PCNL.

Objective To investigate the clinical efficacy of exercise cupping plus acupuncture in treating acute lumbar sprain. Method Sixty-four patients with acute lumbar sprain were randomly allocated to treatment and control groups, 32 cases each. The treatment group received exercise cupping plus acupuncture and the control group, acupuncture alone. After one treatment and one course of treatment, the therapeutic effects were evaluated using the VAS for pain, lumbar joint activity and the clinical effect assessment. Result After one course of treatment, the total efficacy rate was 96.9% in the treatment group, which was significantly higher than 84.4% in the control group (P<0.05). After one treatment and one course of treatment, the VAS score was significantly lower in the treatment group than in the control group (P<0.05) and lumbar joint activity improved significantly in the treatment group compared with the control group (P<0.05). Conclusion Exercise cupping plus acupuncture is more effective than acupuncture alone in treating acute lumbar sprain.

Objectives To investigate the clinical significance of degree Ⅲ meconium-stained amniotic fluid in term pregnancy.Methods Data of 857 full-term gravidas underwent cesarean section for suspected fetal distress in Peking University First Hospital from October 1,2012 to September 30,2014 were retrospectively analyzed.All patients were divided into three groups according to the diagnosis of suspected fetal distress:meconium-stained amniotic fluid group (Group 1,n=172),fetal heart abnormality group (Group 2,n=623) and meconium-stained amniotic fluid in combination with fetal heart abnormality group (Group 3,n=62).General information and fetal prognosis of the three groups were analyzed.Factors that might affect the prognosis of newborns were analyzed between the infants with or without acidosis,asphyxia or aspiration pneumonia.Analysis of variance,independent-samples t test,Chi-square test and rank-sum test were used as statistical methods.Results There were no significant differences in maternal age,gestational age at delivery,parity,nuchal cord loop(s),pH value of umbilical arterial blood and gender of newborns among the three groups (all P＞0.05).The neonatal Apgar score,neonatal asphyxia rate and rate of admitting into pediatric ward within 24 hours after birth in Group 1 were similar to those of Group 2 and 3 [1 min Apgar score:9.9±0.7 vs 9.8±0.7 and 9.8±0.7,F=0.322;5 min Apgar score:10.0±0.3 vs 10.0±0.2 and 10.0±0.0,F=0.517;neonatal asphyxia rate:1.7％ (3/172) vs 2.1％ (13/623) and 1.6％ (1/62),x2=0.129;rate of admitting into pediatric ward:16.3％ (28/172) vs 14.3％ (89/623) and 11.3％ (7/62),x2-0.978] (all P＞0.05).The incidence of neonatal aspiration pneumonia in Group 1 was higher than that of Group 2 and 3 [4.7％ (8/172) vs 3.2％ (2/62) and 1.0％ (6/623)],but the differences had no statistical significance (F=10.680,P=0.050).Conclusions Both degree Ⅲ meconium-stained amniotic fluid and abnormal fetal heart rate have the same indicating significance and should be treated actively to lower the risk of poor prognosis of the newborns.

Obesity increases the risk of ovarian cancer,and it is associated with the poor prognosis of ovarian cancer.Its pathogenic mechanism may be associated with the increased level of serum estrogen,insulin and insulin-like growth factors-1 induced by obesity and a variety of adipocytokines,which has an impact on the therapeutic result and prognosis of ovarian cancer.Maintaining a proper weight may prevent the development of ovarian cancer.
