ABSTRACT

Objective:To investigate the efficacy and safety of green laser vaporization enucleation of the prostate with end-fire fiber in the treatment of benign prostatic hyperplasia.Methods:The clinical data of 218 patients with benign prostatic hyperplasia admitted to Zhejiang Provincial People's Hospital from August 2018 to July 2019 were retrospectively analyzed. All 218 patients presented symptoms of varying degrees of frequent voiding, urgency, nocturia, and progressive dysuria, with age of(76.2±8.4) years, prostate volume of(77.3±21.6) ml, and preoperative PSA of (3.5±0.9)ng/ml, preoperative maximum urine flow rate (Qmax)of(7.9±1.8)ml/s, residual urine volume of(82.3±26.3)ml, quality of life score(QOL) of(4.9±1.1)points, and International Prostate Symptom Score (IPSS) of (25.4±7.6) points. Lithotomy position was used intraoperatively, and intravenous combined general anesthesia or intraspinal anesthesia was performed before the green laser vaporization enucleation of the prostate. Intraoperatively, green laser equipment used a vaporization power of 80W, an optical fiber with a end-fire fiber of 800μm in diameter, and hemostasis power of 20W. The surgical procedure was firstly to vaporize and cut 3 grooves from the bladder neck to the ejaculatory hole plane of the prostate at 5, 7 and 12 o'clock, reaching deep enough to expose the surgical capsule, in order to set up" three lines and one side" anatomical landmarks. A combination of sheath peeling and vaporization cutting along the envelope layer was used to enucleate the hyperplastic glands according to the " three-leaf " method. After enucleation, the tissue was pushed into the bladder, and the enucleated tissue was crushed and aspirated with a tissue morcellation. Perioperative and postoperative parameters including vaporized enucleation time, tissue morcellation time, hemoglobin changes, bladder irrigating time, indwelling catheterization time, postoperative hospital stay, postoperative Qmax, residual urine volume, postoperative complications, IPSS and QOL were recorded. Urgency with involuntary urine leakage was diagnosed as urge incontinence, involuntary urine leakage after coughing was diagnosed as stress urinary incontinence, and the incontinence degree was defined according to the amount of pad used, with mild of 1-2 pads/day, moderate of 3-4 pads/day, and severe of 5 or more pads/day.Result:All 218 operations were successfully completed. Capsule perforation occurred in 8 cases(3.7%), and there was no bladder perforation. The time of vaporization and enucleation was (42.5±8.3)min, and the time of tissue morcellation was(12.1±3.4)min. The intraoperative and postoperative hemoglobin loss was(4.7±1.3)g/L, and there were no blood transfusion or re-operation for stopping bleeding. The average bladder irrigation time after operation was(6.3±1.6)h, the average indwelling catheterization time was(1.2±0.2)days, and the average postoperative hospital stay was (2.2±0.7)days. The Qmax 1 month after operation was(18.5±4.8) ml/s, and the residual urine volume of the bladder was(6.4±1.9)ml, which showed a statistical difference compared with the preoperative parameters( P<0.01). In addition, the QOL(2.1±0.4) and IPSS(7.1±2.1)showed a statistical difference at 3 months follow-up, compared with the parameters before or 1 month after the operation( P<0.01). The volume of the prostate at 3 months after the operation was(34.6±6.3) ml, and the PSA was(2.4± 0.5) ng/ml, which was statistically different from the preoperative corresponding parameters( P<0.01). During the follow-up within one year, 11 cases were detected incontinence during the 1-month follow up, including 6 cases of urge incontinence. After drug treatment, good continence achieved 3 months after the operation. The other 5 cases had stress urinary incontinence, 3 of whom got good continence after the drugs treatment and pelvic floor muscle exercise, and two patients recovered to one pad per day. A total of 24 cases of urethral stricture were found during the 12-month follow-up, including 16 cases of anterior urethral stricture, which was treated with 3 months of regular urethral dilation. Another 8 cases had bladder neck contracture, and were treated by bladder neck resection and regular urethral dilatation. All of them did not recur 6 months after the procedure. Conclusions:The end-fire green laser vaporization enucleation of the prostate has the advantages of short operation time, less intraoperative bleeding, and obvious improvement in postoperative symptom scores. The short-term effect is obvious, and the long-term effect still needs further study to confirm.

ABSTRACT

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.

ABSTRACT

Objective:To investigate the viral molecular mutations of 2019 novel coronavirus (2019-nCoV) and host adaptability in Suzhou City.Methods:The throat swab specimens from nine local cases and six imported cases with 2019-nCoV viral nucleic acid test positive in Suzhou City were sequenced for the whole genome of the virus, and the Wuhan-Hu-1 strain was used as the reference sequence for alignment and analysis. The phylogenetic tree of the viral whole genome sequence was constructed by MEGA 7.0 software.Results:According to the Chinese typing method, Nextstrain typing method, Pangolin classification method and Global Initiative on Sharing All Influenza Data (GISAID) typing method, the 15 2019-nCoV genome sequences could be divided into seven types, six types, eight types and five subtypes, respectively. Compared with Wuhan-Hu-1 strain, the median number of amino acid sequence mutation sites based on nucleotide translation was three (ranging from 0 to 12). D614G mutation of spike protein was identified from all six imported viral strains, which could enhance the transmissibility. No Alpha, Beta, or Gamma mutants, which also could enhance the transmissibility, was found in the genomic sequences of the imported cases. The median number of nucleotide mutation sites in 15 sequences was eight (ranging from three to 23).Conclusions:2019-nCoV is constantly mutating, and a variety of evolutionary lineages/genotypes have been derived. All imported viruses in Suzhou City carry mutations that can increase infectivity.

ABSTRACT

Objective:To explore the feasibility, safety and clinical efficacy of ileum augmentation cystoplasty assisted by Da Vinci robot for the treatment of neurogenic bladder.Methods:Retrospective analysis was performed on the data of 12 patients with neurogenic bladder admitted to Zhejiang Provincial People’s Hospital from March 2017 to November 2018, including 11 males and 1 female, with the mean age of 38(12-67). Preoperative symptoms were urinary incontinence, dysuria, decreased bladder capacity, or increased bladder pressure leading to ureteral reflux. All the 12 patients underwent preoperative intermittent catheterization, including 8 patients with spinal cord injury and 4 patients with spinal cord dysplasia. Preoperative serum creatinine(129.58±44.60)μmol/L and total glomerular filtration rate(61.63±18.04)ml/(min·m 2) were observed in 12 patients. Preoperative urodynamic examination showed the safe bladder volume of (95.67±39.10)ml, bladder internal pressure of(63.30±6.02)cmH 2O(1 cmH 2O=0.098 kPa)at the end of filling period, bladder compliance of(10.24±1.14)ml/cmH 2O, residual urine volume of(152.58±80.89)ml, and urine flow rate of(3.88±3.63)ml/s. Bladder contracture was evident on preoperative cystography. Ultrasound examination showed different degree of hydronephrosis and ureter expansion, in all cases, with ureteral reflux grading Ⅰin 2 cases, grade Ⅱ in 4 cases, grade Ⅲ in 4 cases, grade Ⅳ in 2 cases. All the 12 patients underwent robot-assisted ileum augmentation cystoplasty with 5-point puncture. Transverse incision of the bladder wall before full thickness, according to the amount of bladder and quality to decide 30 cm(normal), longitudinal cut back loops and one point after suture fixation in the bladder wall midpoint, fixed point as starting point, in turn, will be blind to the bladder stitching on both sides, the bilateral ureteral placing a single J tube respectively, evaluation of surgical success rate (including intraoperative bleeding, interception of bowel loops are no damage adjacent viscera, ureter openings with and without damage, impermeability, match insufflate whether unobstructed), postoperative complications, anastomotic fistula, intestinal obstruction, abdominal bleeding), urine dynamics test parameters, and patients’ quality of life. Patients were regularly given anticholinergic drugs(2 mg/d) for 6 months after surgery. Results:All the 12 cases in this group were successfully completed without any transfer to open surgery. The operation time was(120.8±12.0)min. Intraoperative blood loss(84.0±23.2)ml. Postoperative intestinal function recovery time(3.3±1.3) d. Postoperative hospital stay(12.1±3.1)d. Postoperative pelvic drainage tube indwelling time (3.8±1.2) d. Catheter and single J tube were removed 2 weeks after operation. Postoperative follow-up averaged 19.4(3-24) months. At 3, 12, 24 months after surgery, the bladder safety volume was rechecked(435.83±33.56), (450.90±31.09), (462.00±33.72)ml, the bladder internal pressure at the end of filling was(18.60±0.92), (15.70±1.42), (12.96±1.34)cmH 2O, the blood creatinine level was(81.43±21.10), (74.34±15.70), (72.90±15.90)μmol/L, and the bladder compliance was(37.94±4.22), (40.40±3.98), (43.42±4.20)ml/cmH 2O and the total glomerular filtration rate(91.52±9.49), (102.18±5.65), (112.41±6.50)ml/(min·m 2) were significantly improved compared with those before surgery( P<0.001). After 24 months of bladder urination training, 1 patient could basically urinate by herself. Three patients were treated with intermittent urinary catheterization supplemented by automatic urination. The remaining 8 patients were completely dependent on urinary catheter for intermittent catheterization. Postoperative complications such as anastomotic fistula, ileus and abdominal bleeding were not found in 12 patients. Conclusions:Ileum bladder enlargement assisted by robot can effectively expand bladder volume, reduce bladder internal pressure, improve bladder compliance, prevent ureteral reflux and protect renal function.

ABSTRACT

Objective:To study the feasibility, efficacy and safety of low-power greenlight laser vaporization and enucleation with end-fire fiber in the treatment of large-volume (>90 ml ) benign prostatic hyperplasia.Methods:A retrospective analysis of 138 patients with benign prostatic hyperplasia volume greater than 90ml at Zhejiang Provincial People's Hospital from January 2016 to July 2018. The average age of the patients was (73.5±7.3) years and the average prostate volume was (110.2±23.7) ml, the median maximum urine flow rate before surgery was 5.3 (1.0-10.0)ml/s, and the median residual urine before surgery was 78.5 (51.6-108.5) ml. All patients underwent transurethral enucleation with greenlight laser vaporization and enucleation. The intraoperative vaporization power was 80 W and the optical fiber was end-fire fiber, the hemostasis power was 20 W. The optical fiber was straight out of the greenlight laser fiber. The combination of green laser vaporization and blunt dissection of the lens sheath was used to find the capsule, and the " three-leaf method" was used to enucleate the two and middle lobes of the prostate along the capsule level. After the enucleation, the tissues were pushed into the bladder, and the tissue morcellation was used. The tissue was crushed and removed after enucleation. After operation, an F20 three-cavity catheter was placed, and the balloon was filled with 50 ml of water. After 24 hours, the bladder was given a normal saline irrigation, and the catheter was removed 48 hours after the operation. Statistical analysis of these patients' baseline characteristics, perioperative results and complications.Results:The operation of 138 cases was successfully completed. The time of vaporization and enucleation was (58.6±6.1) minutes, and the time of morcellation was (12.6±5.6) minutes. Intraoperative and postoperative hemoglobin loss was (6.2±1.5) g/L, and no transfusion was required. Postoperative pain score(NRS) of 89 cases was 0, and 49 cases was 1. 123 patients who were removed catheter after 48 hours could urinate well, and 15 patients need re-catheterization. The catheter was removed again 7 days after surgery, and all patients returned to normal urination. Two cases of transient urinary incontinence occurred after the operation, both of which were urgent urinary incontinence. Both patients improved after oral tolterodine treatment and there was no stress urinary incontinence. There were 5 cases of urethral stricture after operation, all of which occurred 3 months after operation. They were cured after urethral stricture dilation or bladder neck orifice resection. The median maximum urinary flow rate was 17.5 (14-22) ml/s and the residual urine was 6.2 (2.7-11.3) ml in 1 month after operation, which were significantly different from preoperative parameters ( P <0.05). The maximum urinary flow rate was 16.1 (13-20) ml/s at 3 months postoperatively and 17.3 (11-24) ml/s at 12 months postoperatively, and remained stable. Conclusions:Low-power greenlight laser vaporization and enucleation in treating large-volume>90 ml has the advantages of short operation time, less pain, less blood loss, and quick recovery after surgery. The incidence of urinary incontinence and postoperative cardiovascular accident is low.

ABSTRACT

Objective:The clinical efficacy, safety and quality of life in female patients with stress urinary incontinence (SUI)treated by midurethral sling were studied by multicenter retrospective study.Methods:From January 2018 to December 2018, 531 female patients with severe stress urinary incontinence from seven domestic urinary center were included in this study, including 78 cases from General Hospital of Central Theater Command, 122 cases from Shanghai Jiao tong University School of Medicine Affiliated Ren Ji Hospital, 67 cases from Shanghai Jiaotong University Affiliated First People’s Hospital, 68 cases from People’s Hospital of Jiangsu Province, 71 cases from The First Affiliated Hospital of Xi’an Jiaotong University, 65 cases from Zhejiang Provincial People’s hospital, 60 cases from Xiamen University First Affiliated Hospital. Among the 531 patients, 214 cases received TVT sling with an average age of (58.14±10.16) years. 181 cases were in postmenopausal(84.6%). The number of births ≥2 times was 89 (41.6%) cases. The score of ICI-Q-SF was 16.00±1.73. There were 166 cases of moderate incontinence (77.6%) and 48 cases of severe incontinence (22.4%). There were 317 patients in the TOT/TVT-O group with an average age of (58.33±10.25) years. 247 cases were in postmenopausal(77.9%). The number of births ≥2 times was 120 (37.8%) cases. The score of ICI-Q-SF was 15.79±1.75. There were 256 cases of moderate incontinence (80.8%) and 61 cases of severe incontinence (19.2%). There was no statistically significant difference in general data parameters between the two groups ( P>0.05). 1, 6, 12 months after the operation, the two groups of patients incontinence questionnaire Summary(ICI-Q-SF), common complications and Patient Global Impression of Improvement(PGI-I), satisfaction evaluation follow-up. ICI-Q-SF score improved > by 50% (cure + significant improvement) and 1-hour pad test <10 g (qualitative index) were used as the evaluation index of surgical success. Result:Both of the two surgical methods have high successive rate. There was no significant difference between 94.9% (203/214) of the TVT group and 93.7% (297/317) of the TOT/ TVT-O group ( P>0.05). Postoperative improvement of urinary incontinence (cure rate) [88.3% (189/214)]in the TVT group was slightly higher than that in the TOT/ TVT-O group [77.0% (244/317)] ( P<0.05). There was no change in the recurrence rate of urinary incontinence in the follow-up 6 and 12 months after the operation. There was no statistically significant difference between 4.4% (9/203) in the TVT group and 5.4% (16/297) in the TOT/TVT-O group ( P>0.05). The subjective cure rate 12 months after the operation was 96.3% (206/214) in the TVT group and 95.9% (304/317) in the TOT/TVT-O group ( P>0.05). 10 patients occurred bladder perforation occurred in the TVT group, and no bladder perforation occurred in the TOT/TVT-O group ( P<0.001). The incidence of pain and discomfort in the TVT group was significantly lower at 1.9% than that in the TOT/TVT-O group at 6.9% ( P<0.01). There was no statistically significant difference between the two groups in the incidence of complications such as dysuria/urinary retention, frequent urination/urgency incontinence. Both of them exposed sling ( P>0.05). Conclusion:Both TVT and TOT/TVT-O sling can effectively treat female stress urinary incontinence, and both can improve the sexual satisfaction of patients after the surgery, with fewer complications and other advantages. The selection of specific surgical methods in clinical practice can be individualized according to the patient's physical conditions, clinical needs and the operation methods familiar to doctors.

ABSTRACT

Objective:To investigate the safety and efficacy of sacral neuromodulation(SNM)therapy for the treatment of lower urinary tract dysfunction(LUTD)in elderly patients.Methods:Clinical data of 91 elderly patients with LUTD from multiple medical institutions who received SNM during the period from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into four groups: the interstitial cystitis(IC)group(n=28), the neurogenic bladder(NB)group(n=36), the overactive bladder syndrome(OAB)group(n=13)and the idiopathic dysuria(ID)group(n=14). Different sets of evaluation parameters were used for different diseases.Patients’ baseline data and data in stage I(test phase)and stage Ⅱ(permanent SNM)were recorded, statistically analyzed and compared.Results:Ninety-one people underwent SNM treatment.Of them, 53 patients received permanent implants(stage Ⅱ), and the total conversion rate of stage I to stage Ⅱ was 58.2%(53/91). Patients receiving permanent implants(stage Ⅱ)had a preoperative period ranging from 3 months to 30 years, and were followed up for 2 to 58 months after treatment, with an average follow-up of 19.6 months.The improvement rates in stage I for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 35.4%, 31.6%, 33.7%, 32.6%, 49.2%, 43.2% and 13.2%, respectively.The improvement rates in stage Ⅱ for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 43.2%, 40.0%, 37.8%, 50.5%, 70.5%, 70.4% and 43.2%, respectively.Three adverse events occurred, including 1 case of recurrent symptoms, 1 case of moderate infection, and 1 case of electrical lead dislocation.Conclusions:Sacral nerve stimulation has definitive and consistent curative effects on LUTD in elderly people.The follow-up time should be extended to further study the safety of sacral nerve stimulation.

ABSTRACT

This study aims to investigate the efficacy and safety of sacral neuromodulation [SNM] in treating juvenile neurogenic chronic urinary retention [NCUR]. The clinical data of three juvenile NCUR patients treated with SNM from June 2013 to December 2014 were retrospectively analyzed. The results of urodynamic examination of these three patients were all weak detrusor contraction. Nerve leads were implanted into the 3[rd] sacral nerve for 4-week in vitro testing. Urination diary, residual urine volume, constipation score and urodynamic parameters were recorded to assess the results. All these patients received significant improvements, so they subsequently underwent permanent implantation of the stimulator. The symptoms of dysuria, frequent urination and constipation were significantly reduced after surgery, and the residual urine volumes were decreased to 20 ml, 50 ml and 20 ml, respectively. Urination diary and urodynamic parameters were improved, compared with those before surgery. The patients were followed up until 18, 23 and 6 months after surgery, with stable efficacies and no adverse reaction. SNM could improve such symptoms as urination and constipation in juvenile NCUR patients, and the safety was high

ABSTRACT

A RIA method for determining human plasma parathyroid hormone (hPTH1-34) was established. This was possible mainly by the production of an antiserum of high liter raised in rabbit against hPTH1-34. The methodological investigation data were listed below: the affinity constant, Ka= 1,95?1010 mol/L; the cross reactivity with each of the three analogous peptides, i.e., hACTH1-34, hCT and hPTH44_68, being all less than 0.005%; the intra- and inter-batch coefficients of variation being 6.0% and 13.0% respectively; the recoveries for different levels of hPTH1_34 being ranged within 83.1 - 102.6%; and the sensitivity being 1.1 pmol/L. The reference value obtained by testing 50 male and 50 female normal adults was 11.7 ?4.4 pmol/L. It has been applied clinically for patients with various endocrine diseases including hyper- and hypoparathyroidisms and metabolic bone diseases especially in the aged population and the results fitted well with clinical diagnosis.
