Objective To explore the surgical treatment for ipsilateral femoral neck and shaft fractures.Method From December 2000 to March 2007,13 patients with ipsilateral femoral neck and shaft fractures were treated,7 patients were stabilized with reconstruction inter-locking nail,3 patients were stabilized with cannulated lag screws and retrograde inter-locking nail,and the other patients who were missed diagnosis were stabilized with cannulated lag SCreWS and antergrade inter-locking nail.Results All patients were followed up for 18 months to 5 years,and had fracture union at one stage,except 1 patient had nonunion offemoral neck fracture and 1 patient had nonunion offemoral shaft fracture.Conclusions The ipsilateralfractures offemoralneck and shaftismre.andthefemoral neckfractureis easyto bemissed.The treating method should be chosen according to the position of femoral shaft fracture.

Objective To explore the clinicopathological characteristics of hereditary ovarian cancer syndrome(HOCS). Methods From Jan. 2000 to Jan. 2007, among 580 cases of primary ovarian cancer, 42 cases(herediatary group),who had a positive family history of ovarian cancer and met the diagnostic criteria of HOCS, were analyzed retrospectively. One hundred cases without a family history of ovarian cancer were enrolled randomizely as control group (sporadic group). Results The incidence of HOCS was 7.2% (42/580). Forty-two cases associated tumors affected at least 2 successive generations in 31 families and affected 1 generation in 8 families. Eighty-seven percent (27/31)was from maternal lineage, while 13% (4/31)from paternal lineage. Earlier age of onset was significantly difference between two groups[(49±10) years vs. (55±10) years, P<0.05]. There were 90% belong to serous adenocarcinoma in the herediatary group, while 84% in the sporadic group. There was statistical difference in the proportion of mucinous adenocarcinoma (0 vs. 11%, P<0.05). The most common clinical manifestations were abdominal distention and anorexia (64% vs. 70%, P>0.05), International Federational of Gynecology Obstetrics(FIGO)stage Ⅲ (62% vs. 63%, P>0.05) between two groups. Fourteen cases (33%,14/42) were previously untreated in the herediatary group, while 40 cases (40%, 40/100) in the sporadic group. There were 15 cases (36%, 15/42) underwent secondary surgery and 15 cases (36%, 15/42) underwent third surgery or more in berediatary group, while 50 cases (50%, 50/100) and 27 cases(27%, 27/100) in the sporadic group. The mean number of ehemotberapy cycles received in two groups was 13.3 and 11.8 (P>0.05). The 3-year and 5-year survival rate in herediatary group were 73.6% and 54.9% respectively, compared with 47.4% and 21.2% (P<0.05) in sporadic group. Conclusion Hereditary ovarian cancer mostly from maternal lineage are featuring in early age of onset, serous adenocarcinoma, advanced stage (stage Ⅲ), and better prognosis after the comprehensive treated by cytoreductive surgery plus with chemotherapy.

OBJECTIVETo investigate the genetic diversity and structure of Dendrobium huoshanense, a (CT)n enriched microsatellite library was constructed using a magnetic beads enrichment procedure.

METHODThe 3'-biotinylated oligonucleotide probe was used to hybridize with the digested D. huoshanense genomic DNA fragments whose both ends were ligated with adaptors. The hybridized complex was then combined with the streptavidin-coated magnetic beads. The captured microsatellite fragments were eluted, collected and cloned into pMD19-T vector. The recombinant plasmids were transformed into Escherichia coli DH5alpha competent cells. The clones that yielded two or more bands contained microsatellite fractions. Positive clones were screened and sequenced. Thirty pairs of primers were designed and synthesized. Polymorphism at each locus was determined using 24 individuals from a natural population from Huoshan county town in Anhui province.

RESULTTwelve polymorphic microsatellite loci from the microsatellite-enriched genomic library were newly developed across 24 D. huoshanense individuals. In total, 65 alleles were identified, and the number of alleles per locus ranged from 2 to 8. The mean observed and expected heterozygosities were 0.500 and 0.638, respectively. Two loci significantly deviated from Hardy-Weinberg equilibrium (P<0.05), which could be due to the presence of null alleles. Furthermore, three of twelve loci showed significant linkage disequilibrium (P<0.05).

CONCLUSIONThese results suggest that the identified polymorphic microsatellite markers will be useful in population genetic studies of D. huoshanense.

Objective:To explore the application effect of home rehabilitation exercise prescription in non-surgical treatment of patients with lumbar disc herniation.Methods:Using the convenient sampling method, a total of 66 patients with non-surgical treatment of lumbar disc herniation who visited Outpatient Department of the First Affiliated Hospital of Zhengzhou University from January to August 2023 were selected as the research objects. The patients were divided into the control group and the observation group using the random number table method, with 33 cases in each group. The control group implemented routine home rehabilitation nursing measures, while the observation group formed an outpatient home rehabilitation nursing team based on this, constructed a home rehabilitation exercise prescription and implemented targeted home rehabilitation training. Pain Numberic Rating Scale (NRS), Oswestry Disability Index (ODI), Modified Japanese Orthopaedic Association (JOA) Scores and exercise compliance were compared between the two groups after 6 weeks of home rehabilitation.Results:After 6 weeks of home rehabilitation exercise, NRS score and ODI score of observation group were lower than those of the control group, and the differences were statistically significant ( P<0.05). The JOA score and compliance score of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Home rehabilitation exercise prescription can promote the rehabilitation of patients with non-surgical treatment of lumbar disc herniation, effectively relieve pain, improve the symptoms of limb dysfunction and improve the compliance of rehabilitation exercise.
