When adult developmental dysplasia of hip (DDH) patients have developed secondary os- teoarthritis of hip (OAH) with serious clinical symptoms,total hip replacement (THR) is their first choice of treatment.The anatomic structures of the acetabulum and femur in these patients are ahnormal and special,such as small and shallow cup,small femoral head,and narrow medullary cavity at proximal femoral shaft.As a result,the THR for DDH patients is quite different from the conventional ones and is thus highly difficult.We review in this paper the clinical classification of DDH,which is important for its treatment,the difficulties we will have in THR, especially in acetabular reconstruction and femoral prosthesis placement,and also strategies to resolve them.

Objective To investigate the diagnostic value of multi-slice spiral CT (MSCT) perfusion imaging combined with serum cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), carcinoembryonic antigen (CEA) and neuron specific enolase (NSE) for peripheral non-small cell lung cancer (NSCLC). Methods Based on diagnosis, 109 patients with suspected peripheral NSCLC admitted from Aug. 2017 to Aug. 2019 in the Xinxiang Central Hospital were divided into peripheral NSCLC group (n=65) and benign pulmonary nodule group (n=44). Another 56 healthy subjects undergone physical examination during the same period were selected as control group. The parameters of MSCT perfusion imaging and serum levels of CYFRA21-1, CEA and NSE in the 3 groups were compared. The receiver operating curve (ROC) was used to analyze the diagnostic value of MSCT perfusion imaging combined with serous levels of CYFRA21-1, CEA and NSE for peripheral NSCLC. Results The blood volume (BV) was larger in peripheral NSCLC group than those in benign pulmonary nodule group and control group [(10.76±1.26) ml/100 mg vs. (4.01±0.59) ml/100 mg and (2.32±0.42) ml/100 mg]; the same was for surface permeability (PS) [(42.56±5.60) ml/ (100 mg·min) vs. (16.13±1.88) ml/(100 mg·min) and (8.49±0.91) ml/(100 mg·min)]; and for the mean transit time (MTT) of contrast medium [(20.14±3.67) s vs. (12.85±1.49) s and (7.21±0.95) s]. All the BV, PS and contrast medium MTT were higher (larger) in benign pulmonary nodule group than those in control group (P<0.05). The serum level of CYFRA21-1 was higher in peripheral NSCLC group than that in benign pulmonary nodule group and control group [(8.94±1.67) ng/ml vs. (4.73±0.51) ng/ ml and (1.93±0.26) ng/ml]; the same was for the CEA level [(27.91±3.25) ng/ml vs. (7.88±0.92) ng/ml and (2.06±0.47) ng/ml]; and for the NSE level [(19.53±2.16) ng/ml vs. (15.02±1.74) ng/ml and (11.96±1.22) ng/ml]. All the serum levels of CYFRA21-1, CEA and NSE were higher in benign pulmonary nodule group than those in control group (P<0.05). The ROC results showed that the diagnosis of peripheral NSCLC alone and combined with MSCT perfusion imaging, serum levels of CYFRA21-1, CEA and NSE were 0.802, 0.794, 0.698, 0.712 and 0.841, respectively. The diagnostic value of combined detection of the four methods was higher than that of individual detection. Conclusion MSCT perfusion imaging combined with serum levels of CYFRA21-1, CEA and NSE have high diagnostic value for peripheral NSCLC.

The surface-enhanced Raman spectra of bilirubin and biliverdin were obtained.By the bands analysis of the spectra,the orientation of bilirubin and biliverdin on the surface of silver colloid was discussed.In such case,the bilirubin was adsorbed on the silver colloid particle with the two planar pyrromethenone groups intercalated into the globe silver colloid particle,however,the biliverdin might lie flat on the surface of silver colloid with syn-synsyn conformation.

Chitinases genes from Metarhizium anisopliae which is an important entomopathogenic fungus were considered one of the key factors to invade their hosts. One Metarhizium anisopliae HN1 strain was isolated and screened. A chitinase gene was amplified by RT-PCR from Metarhizium anisopliae HN1, The whole length of this gene was 1275bp,and the nucleotide sequence of the gene was 96% similarity to that of the M. anisopliae E6 accessed in GenBank ( AF02749). The gene has been registered in GenBank and its accession number is DQ011865. The gene was subcloned into prokaryon expression vector pET-22b( + ), transformed this recombinant expression plasmid into E. coli strain BL 21 and effective expressed. The SDS-PAGE analysis indicated that the recombinant protein was 42kDa which is same to the reported article. The expression level of recombinant protein was about 63. 3% of whole expressed proteins , And when recombinant E. coli were crushed by freeze and supersonic wave , the activity assay indicates that the chitinase expressed in bacteria possesses biological activity.

In order to obtain active recombinant PNGase F in Escherichia coli, a prokaryotic expression vector pET28a/PNGase F was constructed. Amplification of PNGase F was obtained using PCR technique employing suitable primers designed according to the PNGase F gene sequence from Flavobacterium nmeningosepticum. The expression of PNGase F gene in LB medium or M9 medium led to the formation of inclusion body and soluble protein, respectively. The refolding of the denatured inclusion body was successful by gradual dilution. Further purification of the refolded protein and soluble crude extract from M9 medium with Ni2+ -NTA argarose resulted a 90% purified PNGase F. The purified protein catalyzed the complete and intact cleavage of N-linked oligosaccharides from various glycoproteins. The efficiency of this cleavage was affected by the substrate status in the reaction system. In summary, we have developed an enzyme production system where PNGase F was over-expressed in recombinant E. coli. This system can provide more than 15 mg/L purified active PNGase F. This purified active PNGase F can be used as tools in analyzing the oligosaccharide structure.

OBJECTIVETo study the effect of Zhibai Dihuang Pill (ZBDHP) on urokinase-type plasminogen activator (uPA) and sperm quality in ureaplasma urealyticum (Uu) infection infertile patients.

METHODSRecruited were 80 infertility patients with Uu infection at Andriatrics Clinics and Department of Reproduction, including 130 cases of positive Uu semen and 50 cases of negative Uu semen. Patients with positive Uu semen were randomly assigned to the observation group (72 cases) and the control group (58 cases) according to the visit sequence. All patients took antibiotics for 2 weeks. Patients in the observation group additionally took ZBDHP, 6 g each time, twice daily. Those in the control group additionally took Vit E (100 mg each time, twice per day) and ATP (40 mg each time, twice per day). The therapeutic course for all was 90 days. Semen parameters and uPA contents of the sperm membrane were detected and comparatively analyzed.

RESULTSThe sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm in Uu positive infected patients were lower than those in Uu negative infected patients with statistical difference (P < 0.05), but with no significant difference in the sperm density between the two groups (P > 0.05). There was no statistical difference in pre-treatment sperm membrane uPA contents and sperm parameters between the two groups (P > 0.05). Compared with before treatment in the same group, the sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm obviously increased in the two groups with statistical difference (P < 0.05). After treatment, the sperm membrane uPA content increased more obviously in the observation group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONSInfection with Uu leads to decreased uPA content of sperm membrance and the sperm motility. ZBDHP could effectively treat Uu infected infertility possibly through fighting against Uu damaged sperm membrane and make the sperm membrane uPA content return to normal, and elevate the fertilizability of sperms.

OBJECTIVETo evaluate the efficacy of late accelerated hyperfractionated conformal radiotherapy (LACF) combined with capecitabine on esophageal carcinoma.

METHODSOne hundred and sixty eight patients of esophageal cancer were randomly divided into 3 groups, including the radiotherapy alone group (CF) which received conventional conformal radiotherapy to a total of 60 - 66 Gy, LCAF group which received conventional fractionated conformal radiotherapy during the first two-thirds of the treatment to a dose about 40 Gy/20F/4W, then followed by late accelerated hyperfractionated conformal radiotherapy, twice daily radiotherapy at 1.3 Gy per fraction to a total dose about 64 - 69 Gy, and LCAF + C group (late accelerated hyperfractionated radiotherapy combined with capecitabine), in which patients were treated as the same as the LCAF group, except that they were treated with capecitabine (1.5 g po bid) from beginning of the radiotherapy to the end.

RESULTSThe short-term results of the 3 groups were 74.0%, 85.5% and 95.2%, respectively (P = 0.006). The local control rates at 1, 3 and 5 years were 64.0%, 30.0%, 24.0% in the CF group, 81.8%, 65.5%, 58.2% in the LCAF group and 90.1%, 77.8%, 74.6% in the LCAF+C group, respectively. The 1-, 3- and 5-year survival rates of the 3 groups were 58.0%, 20.0%, 8.0%; 78.2%, 36.4%, 17.0% and 85.7%, 55.6%, 30.2%, respectively. The effect of LCAF+C group was better than that of LCAF group and CF group. The incidence of acute tracheitis and acute esophagitis in the LCAF+C group and LCAF group was higher than that in the CF group, but there was no stastistically significant difference between the 2 groups. There was no statistically significant difference in distant metastasis in the 3 groups.

CONCLUSIONSCapecitabine, as an effective chemosensitizater combined with late accelerate hyperfractionated radiotherapy can improve the short-term results of treatment of esophageal cancer. The value of this combined treatment in distant metastasis reqires further study in the clinic.

OBJECTIVETo evaluate the effect of integrative medical treatment (IMT) with serial Chinese recipes on quality of life (QOF) of rehabilitation stage in SARS patients.

METHODSEighty-five SARS patients of rehabilitation stage were enrolled in the clinical study. They were divided into the IMT group (62 patients received serial Chinese recipes and western medicine) and the control group (23 patients received western medicine alone). The serial Chinese recipes were given according to patients' syndrome, one dose per day for oral intake for 3 weeks. QOF scoring in patients was observed.

RESULTSQOF scoring in the IMT group before treatment was not significantly different from that in the control group. After 3 weeks treatment, it improved to some extent in both groups, but the improvement in the IMT group was superior to that in the control group in respect of total score and score of psychologic emotional factors.

CONCLUSIONSerial Chinese recipe could improve QOF of rehabilitation stage in SARS patients.
