Objective To observe the clinical effect of Renzi Shengjing Decoction(Radix Ginseng and Fructus Schisandrae decoction for producing sperms)treating oligospermia and aspermia males with kidney yang deficiency through its influence on semen and hormones.Methods The 60 males with infertility due to oligospermia and aspermia were randomly divided into treated group and control group with 30 cases in each.Before and after treatment,the two groups were tested with the colored semen analysis system for detecting the density,motility and survival rate of sperms respectively.The follicle-stimulating hormone(FSH),luteinizing hormone(LH),testosterone(T),and prolactin(PRL)were measured by enzyme-labeling instrument.Results In the treated group,the improvement of semen parameters and sexual hormones and clinical effect were better than those of control group(P

110 patients under three years of age with pneumonia were admitted to this hospital in a period from August of 1982 to March of 1983. There were 68 males and 42 females. The patients were randomly divided into Group A and Group B .The symptoms and signs, the laboratory data, and the severity and duration of the illness of the patients of both groups were similar.After admission, laboratory examinations including WBC counts, throat swab cultures and determinations of immunity function were performed and chest x-ray films were taken for all the patients. Regular treatments were given to all of them but the patients of Group A received TDP radiation in addition.After comparing the clinical courses of the two groups, the authors found that TDP could cause more rapid disappearance of cough and moist rales in the lungs, shorten the time of recovery and the whole course of hospitalization, and hasten the absorption of pulmonary infiltrations as seen from the x-ray films. Furthermore, TDP is helpful to promote the immunity function by raising many immune indices. And the rate of lymphocyte transformation was also increased. Its influence on the bringing down of the fever to normal is not very remarkable.It is concluded that TDP radiation is a simple, safe and effective treatment for pneumonia and it is suitable to be used in children.

110 cases of infantile diarrhoea were admitted to this institute in a period from Aug. 30 to Dec. 22 of 1982.The patients were randomly divided into two groups, the TDP group and the control group. The general condition and the age distribution of the patients of both groups were similar. The patients of the TDP group received only TDP radiation instead of antibiotics and those of the control group received antibiotics therapy but no TDP. Other treatments such as fluid replacement, dietary regulation, etc, were the same in two groups. Stool samples were sent for routine examination and bacterial culture and blood samples for the determinations of the electrolyte levels, CO2CP, and immunity function for all the patients right after admission as well as just before discharge. The cure rate and course of the disease were similar in two groups. However the pathogenic organisms could still be revealed in the stool of the patients of the TDP group after recovery. But the rate of lymphocyte transformation was significantly higher in the patients of TDP group.It is concluded that TDP radiation is a simple, safe and effective treatment for infantile diarrhoea but its therapeutic mechanism remains obscure.

Objective To observe the final adult height (FAH) outcome and influencing factors in Turner′s Syndrome(TS) children treated with recombinant human growth hormone ( rhGH ).Methods Thirty TS children treated with rhGH were compared with 16 TS children without rhGH treatment and were followed up to achieve their FAH.Comparisons were made regarding predicted adult height (PAH),height standard deviation score for chronological age( HtSDScA ),height SDS for BA( HtSDSRA ),and growth velocity ( GV ) between rhGH treatment and without treatment groups and between the onset and by the end of rhGH treatment group.The factors determining FAH were also evaluated.Results FAH in rhGH treatment group was obviously improved as compared with untreatment group[ ( 149.5±6.3 vs 142.4±5.2) cm,P＜0.01 ].FAH in treatment group was positively correlated with height standard deviation score for chronological age ( Ht0 SDSCA ),Hto SDS for BA ( Hto SDSBA ),height age ( HA0 ) at preliminary diagnosis,and correlated with duration of rhGH therapy,duration of estrogen-free rhGH therapy,and PAH0SDS at preliminary diagnosis.Stepwise regression analysis indicated that duration of estrogen-free rhGH therapy and PAH0 SDS were the variables with the greatest identified influence on FAH (F =11.56 and F =86.91,P＜ 0.01 ).FAH in the 45,XO group was significantly different from the mosaicism group (45,XO/46,XX ) [ ( 147.2 ± 6.3 vs 153.3±6.4) cm,P =0.038].Conclusion rhGH treatment is efficacious in improving FAH of TS children,but a variability in the magnitude of the response to rhGH is recognized.Duration of estrogen-free rhGH therapy and PAH0SDS are the variables with the greatest identified influence on FAH,and karyotype may be one of the influence factors.rhGH treatment should be initiated as early as possible and sufficient course of estrogen-free rhGH therapy is needed to yield a satisfactory FAH.

Objective To assess the efficacy of gonadotropin-releasing hormone analogue(GnRHa)with or without recombinant human growth hormone(rhGH)treatment in Chinese short pubertal children with non-growth hormone deficiency.Methods Of 42 short pubertal children(14 males,28 females)without growth hormone deftcieney,the average age was(11.6±0.8)year.30 children were treated with slow release GnRHa with initial dose (100μg·kg-1·d-1,28d)and maintenance dose(60-80μg·kg-1·d-1,28d)labd rgGH with initial dose(0.15IU·kg-1·d-1)and maintenance dose(0.10-0.15IU·kg-1·d-1)for at least 1year.16 of them were still ongoing till the end of the second year.12 children were treated with GnRHa alone by initial dose(100μg·kg-1·d-1,28d)and maintenance dose (60-80μg·kg-1·d-1,28d),and 7 of them remained on it for 2 years.Dynamic changes including annual growth velocity(GV),bone age(BA)/chronologic age(CA)ratio,Tanner stage,height SDS for CA (HtSDSCA),height SDS for BA(HtSDSBA),and predicted adult height (PAHSDS)were observed.Results By the end of the first year tretment with combination therapy,the following parameters:GV,HtSDSCA,HtSDSBA,and PAHSDS all increased significantly(all P<0.05).Treatment with GnRHa alone did not yield significant changes in GV,HtSDSCA,HtSDSBA,and PAHSDS(all P>0.05).Changes in GV,HtSDSBA,and PAHSDS between these two groups were statistically significant(all P<0.05).By the end of the second year treatment,in the combination group,GV slowed from 6.7 to 5.5 cm/year(P<0.05).HtSDSCA,HtSDSBA,PAHSDS increased(all P<0.05).In the group with GnRHa treatment alone,GV slowed from 4.0 to 3.6 cm/year(P>0.05).HtSDSCA,HtSDSBA,PAHSDS increased(all P>0.05).Changes in GV,HtSDSCA,HtSDSBA,and PAHSDS between these 2 groups were statistically significant respectively(all P<0.05).Conclusion This combined treatment regimen significantly impreved the growth by increasing growth rate and delaying bone matumtion in pubertal chidren without growth hormone deficiency.Further study is needed to verify beneficial effects on the final height gain.

Objective To explore the causes of ambiguous genitalia.Methods Clinical data of 106 cases with ambiguous genitalia from Ruijin Hospital of Shanghai Jiaotong University School of Medicine were retrospectively analyzed.DNA fragments of related genes from parts of patients were amplified by means of polymerase chain reaction (PCR) and were directly sequenced to detect gene mutations.Results (1)The 106 ambiguous genitalia patients presented a variety of clinical phenotypes.Karyotype of 42 cases(39.6％)were 46,XX,while 62 cases(58.5％)were 46,XY and 2 cases(1.9％)were abnormal.(2)Forty(95.2％)patients with 46,XX were diagnosed with congenital adrenal hyperplasia(CAH) ;one case(2.4％) was adrenal cortical tumor and one case (2.4％) was 46,XX [sex determining region of Y choromosome (SRY) positive] male syndrome.(3) Fifty-three cases (85.5 ％) out of 46,XY karyotype were directly sequenced with steroid-5-alpha-reductase,alpha polypeptide 2 gene (SRD5A2),androgen receptor gene (AR) and steroidogenic factor-1 gene(SF-1).Sequencing analysis of SRD5A2 revealed 8 patients with compound heterozygous or homozygous mutations.A patient carried a novel missense mutation of SF-1 and another patient had a mutation of AR.(4) One abnormal karyotype was 46,XX/46,XY and the other was 46,XX/46,XY/46,X.+ may.ish (DYZ3 +) (DXZ1-).Conclusions (1) CAH is the most common cause of genital ambiguity in 46,XX patients but some rare causes such as adrenal cortical tumors or SRY positive should not be ignored.(2) To find the causes of 46,XY genital ambiguity,direct DNA sequencing analysis of candidate genes would be the better choice because of the complicate pathogenesis.(3)Abnormal karyotype also can lead to ambiguous genitalia.

Objective To explore the value of amino-terminal propeptide of C-type natriuretic peptide (NTproCNP) in evaluating the efficacy of therapy with recombinant human growth hormone ( rhGH ) in patients with idiopathic short stature (ISS) and isolated growth hormone deficiency ( IGHD ).Methods Forty-eight prepubertal children( IGHD n=25,ISS n=23 ) treated for at least 1 year with rhGH were included.Serum insulin-like growth factor- Ⅰ ( IGF- Ⅰ ) and NTproCNP levels were measured before starting treatment and 6 months later.Twelve months after starting treatment,all patients were assessed and annual growth velocity ( GV ),height standard deviation score ( HTSDS),and gained HTSDS (△HTSDS) were recorded.Results In GHD group,positive relationships between GV and change of IGF- ISDS( △IGF- ISDS ),GV and change of NTproCNP concentrations(△NTproCNP) were found( r=0.407,P=0.044 ;r=0.490,P=0.013 ).GH peak value was also positively associated with IGF- ISDS and NTproCNP before therapy ( r =0.558,P =0.004; r =0.630,P =0.001 ).△IGF- ISDS and △NTproCNP were positively associated after therapy ( r =0.466,P =0.019 ).In ISS group,GV was associated with △NTproCNP ( r=0.845,P＜ 0.01 ).Conclusions NTproCNP is a novel biomarker of growth as its level increases during growth-promoting treatment.Furthermore,IGF- Ⅰ is also valuable in evaluating the efficacy of rhGH therapy in short stature patients.

Objectives To evaluate final adult height(FAH), lipid profile, sexual development, and quality of life in individuals with childhood-onset growth hormone deficiency (CO-GHD) during the transition from childhood to adulthood, to reassess the function of GH-IGF-I axis, and to explore effective managements for different types of GHD in each period. Methods Totally 80 CO-GHD patients were divided into 2 groups; 22 patients with isolated growth hormone deficiency ( IGHD) and 58 patients with multiple pituitary hormone deficiencies (MPHD); 62 male (age ≥18 years) and 18 female ( age ≥ 16 years) patients. The clinical and biochemical parameters, education and occupation, rhGH, and other hormones therapy in the past were followed up. Results rhGH replacement improved FAH of patients with GHD. The incidences of either hyperlipidemia (39.0% , 47.4%) or fatty liver disease (26.8%, 31.6%) showed no statistically significant changes between 2 groups with and without rhGH replacement. Mean value of IGF-I SDS was significantly higher in IGHD group than that in MPHD group (-1.43±0. 31,-3. 01 ±0. 66) ,and also IGFBP3(-2. 10±0. 33,-3. 17±0. 19,all P< 0.05 ). Patients with IGHD had normal sexual development, but the incidence of sexual dysfunction accounted for 79.7% in MPHD group. Conclusions rhGH improves FAH of individuals with CO-GHD. Patients with CO-GHD should be followed during the transition period; GHD patients carry a high risk of metabolic abnormalities in the adulthood; IGHD female can give birth to offsprings; patients with MPHD have gonadotrophin deficiency of varying degrees.

Objective To investigate the clinical characteristics and molecular pathological mechanism of McCune-Albright syndrome ( MAS) in order to provide a guidance for the precision medicine of MAS. Method The clinical data and genetic findings of 41 patients with MAS were analyzed retrospectively. Results (1) MAS girls had the phenotype of peripheral precocious puberty with premature sexual development and high estradiol, low LH and FSH, and the increased volume of uterus and ovary. ( 2 ) In 41 MAS cases, there were 17 cases with GNAS1 gene mutation, and the total positive rate was 41. 5%, of which the classic triad was 66. 7%, two signs 56. 3%, and 12. 5% in only one classic sign. GNAS1 gene mutation was found in 78. 6% of patients with polyostotic fibrous dysplasia of bone, while only 55. 0% in patients with cafe au lait skin spots. Children with precocious puberty and fibrous dysplasia of bone is an important basis for clinical diagnosis of MAS, but cafe au lait skin spots does not seem to be the specifical manifestation of MAS. Conclusion Clinically MAS was lack of typical clinical manifestations, and the most important clinical weight factor for the diagnosis of MAS was peripheral precocious puberty with fibrous dysplasia of bone. GNAS1 gene screening may be helpful to improve the clinical accurate diagnosis of MAS.

OBJECTIVE[corrected] To investigate the mutation at the transmembrane domain of fibroblast growth factor receptor 3 (FGFR3) nucleotide 1138 site for identifying the major pathologic mechanism of achondroplasia (ACH) and to evaluate the efficacy of denaturing gradient gel electrophoresis(DGGE) method for screening the point mutations.

METHODSThe genomic DNA from 17 clinically diagnosed ACH patients where analysed by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) with Sfc I and Msp I restriction endonucleases and by PCR-DGGE technique for screening.

RESULTSG to A transition mutation at nucleotide 1138 was detected in 14/17 of the ACH patients as heterozygotes by PCR-RFLP with Sfc I digestion. No 1138 G to C transition was detected by Msp I digestion. All of the 14 samples with G to A mutation were also found to be positive for point mutation by PCR-DGGE. No mutation was detected in 3 negative samples by PCR-RFLP, implying that there was actually no point mutation in this amplified region.

CONCLUSIONNucleotide 1138 in transmembrane domain of FGFR3 gene is the hot point for mutation in ACH and hence its major pathologic cause. PCR-DGGE is a sensitive and reliable technique for point mutation screening, especially for the heterozygotes.
