OBJECTIVETo observe the clinical effect of Shen-reinforcing and menstrual cycle-regulating therapy (SRMCRT) combined with Western medicine (WM) in treating decline in ovarian reserve (DOR).

METHODSTotally 78 patients with DOR were assigned to the traditional Chinese medicine combined WM group (abbreviated as IM group, 40 cases), and the WM group (38 cases) according to random digit table method. Patients in the WM group were treated with hormone replacement therapy, while those in the IM group additionally received SRMCRT. The therapeutic course for all was 3 consecutive months. The therapeutic efficacy was compared between the two groups. The serum levels of follicle stimulating hormone (FSH), FSH/luteinizing hormone (LH), and estradiol (E2), as well as the development of sinus follicles were compared between before and after treatment in the two groups.

RESULTSThe therapeutic effective rate was 92.5% in the IM group, higher than that of the WM group (73.68%, P < 0.05). The serum levels of FSH, FSH/LH, and E2 decreased (P < 0.05) and the number of the sinus follicle increased (P < 0.05) in the two groups after treatment. Besides, IM was superior in decreasing serum levels of FSH and FSH/LH, and increasing the number of the sinus follicle (P < 0.05).

CONCLUSIONSSRMCRT was an effective method for treating ROD. IM was superior in decreasing serum levels of FSH and FSH/LH, and increasing the number of the sinus follicle.

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.

Objective To compare the different effects of 1% diatrizoate meglumine,2.5% mannitol and water as oral contrasts in PET/CT scan in gastrointestinal tract delineation and 18F-fluorodeoxyglucose (FDG) uptake. Methods Sixty-one patients referred for PET/CT scan without gastrointestinal diseases were divided into three groups randomly ( random number method). One liter of 1% diatrizoate meglumine,2.5% mannitol,or water was orally taken by groups 1 (25 cases),2 (20 cases) and 3 ( 16 cases),respectively before scan. The scan was performed with GE Discovery LS PET/CT scanner in two-dimensional (2D) mode 50 min after 18F-FDG (5.55 MBq/kg) injection. Patients with abdominal lesions were excluded from this study. The degree of gastrointestinal filling and 18F-FDG uptake was evaluated by 3 nuclear medicine physicians using visual analysis according to a 4-grade classification method:none,mild,moderate,and high. Statistically analysis was performed by Kruskal-Wallis,Mann-Whitney and paired t tests.Results Both the differences of serum glucose and insulin levels were not significant before and after contrast taken in group 2. Group 2 had better gastrointestinal filling than that of group 1 and also better than group 3 except in rectum. The stomach,jejunum,ascending,and transverse colon were better filled in group 1 than in group 3. The degree of 18F-FDG uptake of group 3 was significantly higher than that of group 2 in stomach,jejunum and ileum (z= -3. 192,-3.290,-3.290,all P＜0.05),and was also significantly higher than that of group 1 (z = - 3. 603,P ＜ 0.05) in jejunum. The degree of 18 F-FDG uptake of group 3 was significantly lower than that of group 1 in ascending colon (z = - 2. 706,P ＜ 0. 05 ) and was significantly lower than that of group 1 and 2 in transverse and descending colon (z= - 3. 503,- 2.403,- 4.225,-4. 027,all P ＜0.05),and was also significantly lower than that of group 2 in rectum (z = -4. 128,P ＜0. 01 ). The maximum CT values in stomach,jejunum,ileum and ascending colon in group 1 were ( 132 ±23),(191 ±31),(313 ±47) and (374±53) HU,respectively,whose difference was significant (t = -7.088--1.781,all P ＜0. 01 ). Conclusion Oral iso-osmotic mannitol intake has better gastrointestinal filling and less physiological 18F-FDG uptake compared to diatrizoate meglumine and water.

AIMTo evaluate the Rap1A mRNA expression and its significance in the testes of normal and azoospermic subjects.

METHODSA cDNA microarray that contained Rap1A and some other genes such as RBM, EIF1AY was used to identify the differential gene expression profiles between the normal and azoospermic testes. cDNA probes were prepared by labeling mRNA from azoospermic and normal testicular tissues through reverse transcription with Cy5-dUTP and Cy3-dUTP, respectively. The mixed cDNA probes were then hybridized with cDNA microarray (each containing 4096 unique human cDNA sequences). The fluorescent signals were scanned and the values of Cy5-dUTP and Cy3-dUTP on each spot were analyzed and calculated. In situ hybridization was employed to detect the expression of Rap1A in the testes of 10 fertile and 39 azoospermic subjects.

RESULTSOne hundred and twenty-eight differentially expressed genes were found to be possibly related to azoospermia, of which 56 were up-regulated and 72, down-regulated genes. The mRNA expression of Rap1A in the spermatogenic cells of azoospermic was stronger than that in those of the fertile testes.

CONCLUSIONRap1A may play certain roles in the development of azoospermia.

OBJECTIVESTo investigate and discuss the role of CT in the diagnosis and treatment of comminutive distal radius fractures.

METHODSOne hundred and eleven consecutive patients (118 cases of fractures) who were admitted to Jishuitan hospital from January 2003 to January 2005 were included in this study. These patients all need operative treatment and accepted CT scans for better understandings of these injuries and helping to make operation plans.

RESULTSafter comparing the results of X planes and CT scans, considerable differences existing between the two examinations were found in the measurements of articular compression and step-off, gapping, comminution degree and subdislocation. This difference was manifested not only in the alteration of quantity but also in the change of quality.

CONCLUSIONSComputed tomography can provide more vivid and detailed information of fractures for practitioners. Undoubtedly, CT is especially valuable in the evaluation of severity degree and stability of comminutive distal radius fractures, thus it helps us to determine whether operation is obligatory and choose the best method and approach of operation. Moreover, CT can also clearly show the important parts of fractures which need special attention in the process of operation. At the same time, practitioners are required to understand the indications of CT examination completely and know how to choose scan planes properly.

To investigate the relationship between HLA-DQB1* alleles and major beta-thalassemia, the HLA-DQB1* loci typing was performed with polymerase chain reaction-sequence specific primer (PCR-SSP) in 42 unrelated (unconsanguineous) patients with major beta-thalassemia and 45 normal control individuals in Guangdong Province. Results showed that the frequency of HLA-DQB1*06 allele in patient group (19.0%) was higher than that in the control group (4.4%) kappa(2) = 8.961, p < 0.01). Our data suggests that HLA-DQB1*06 allele is associated with pathogenesis of the major beta-thalassemia in Guangdong area.
