Ill River located in north of Tianshan Mountain and Tarim River located in north of Qinghai-Tibetan Plateau were two main distribution areas of this fish. To investigate the genetic diversity and genetic structure ofD. maculates, four populations from Tarim River system and two populations from Ili River system were collected in this study. A 570-bp sequence of the control region was obtained for 105 specimens. Twenty-four haplotypes were detected from six populations, only Kunes River population and Kashi River population shared haplotypes with each other. For all the populations examined, the haplotype diversity （h） was 0.904 8±0.012 6, nucleotide diversity （n） was 0.027 9±0.013 9, and the average number of pairwise nucleotide differences （k） was 15.878 3±7.139 1. The analysis of molecular variance （AMOVA） showed that 86.31% of the total genetic variation was apportioned among populations, and the variation within sampled populations was 13.69%. Genetic differences among sampled populations were highly significant. Fst statistical test indicated that all populations were significantly divergent from each other （P〈0.01）. The largest Fst value was between Yurungkash River population and Muzat River population, while the smallest fst value was between Kunes River population and Kashi River population. NJ phylogenetic tree of D-loop haplotypes revealed two main clades. The neutrality test and mismatch distribution analysis suggested that the fish had went through a recent population expansion. The uplift of Tianshan Mountain and movement of Qinghai-Tibetan Plateau might contribute to the wide genetic divergence of D. maculates in northwest China.展开更多

There is cellular hypersensitivity to UV radiation and to certain chemicals in association with abnormal DNA repair. Patients with defective DNA nucleotide excision repair (NER) have defects in one of seven NER genes;xeroderma pigmentosum variants have normal NER and a defect in a polymerase gene. Study design: This is a case presentation of five patients with the features of xeroderma pigmentosum, aged 48, 26, 15, 14 and 8 years. The first and last patients were males. Each of the first four patients presented with areas of hyper- and hypo-pigmentation over sun exposed body surfaces. Each of them had a minimum of two cutaneous malignancies, distributed on the upper chest, face or scalp. The fifth patient had skin atrophy, with mottled hyperpigmentation and hypopigmentation but had no malignant lesions. Result: The first, second and fourth patients had their lesions surgically excised and the defects were skin grafted. The third patient was treated with radiotherapy. All the lesions were confirmed histologically as squamous cell carcinoma. No recurrence has been observed. Conclusion: Xeroderma pigmentosum in Ghanaians presents with squamous cell carcinoma involving the head, neck and upper trunk. A minimum period of exposure to UV radiation, not precisely known, is required for the development of the lesions. Education on sun avoidance and protective clothing is necessary to prevent morbidity and mortality.展开更多

文摘BACKGROUND Jaffe-Campanacci syndrome(JCS)is a very rare syndrome.The treatment of JCS is more conservative,and most authors recommend that no surgery should be done in asymptomatic patients.The conventional concept holds that the natural course of non-ossifying fibromas(NOFs)grows with the development of bones,and the osteolytic region gradually stops expanding and self-healing through bone ossifying around the lesion and ossification within the lesion.But in this case,the bone lesions were potentially biologically aggressive,which led to severe limb deformities and pain.CASE SUMMARY We present the case of a 5-year-old girl with JCS presenting with not only NOF sand café-au-lait macules,but also showed features not mentioned before,severe limb pain,and at last resulted in amputation.She was admitted to our hospital after presenting with claudication and mild pain over her right thigh,which worsened when stretching or being touched.Skin examination revealed multiple café-au-lait macules on the neck,arm,axilla,and torso,including the nipples and perineum.Radiographs revealed multiple lytic lesions in the proximal part of the right humerus,distal part of the right clavicle,proximal and distal parts of the right femur,and proximal parts of the right tibia and fibula.Curettage and biopsy were performed on the distal part of the right femur.At the age of 7,the girl was re-admitted to our hospital for a pathological fracture in the middle in the right femur and underwent Intralesional excision,internal fixation,bone grafting,and spica casting.At the age of 10,the girl came to our hospital again for severe pain of the right leg.Amputation from the middle level of the right femur was performed.We present the case of a 5-year-old girl with JCS presenting with not only NOFs and café-au-lait macules,but also showed features not mentioned before,severe limb pain,and at last resulted in amputation.She was admitted to our hospital after presenting with claudication and mild pain over her right thigh,which worsened when stretching or being touched.Skin examination revealed multiple café-au-lait macules on the neck,arm,armpit,and torso,including the nipples and perineum.Radiographs revealed multiple lytic lesions in the proximal part of the right humerus,distal part of the right clavicle,proximal and distal parts of the right femur,and proximal parts of the right tibia and fibula.Curettage and biopsy were performed on the distal part of the right femur.At the age of 7,the girl was re-admitted to our hospital for a pathological fracture in the middle in the right femur and underwent Intralesional excision,internal fixation,bone grafting,and spica casting.At the age of 10,the girl came to our hospital again for severe pain of the right leg.Amputation from the middle level of the right femur was performed.CONCLUSION In our opinion,education on preventing pathological fractures and explaining the consequent serious consequences to the parents is a matter of prime significance.At the same time,prophylactic treatment(restricted exercise,support,or surgery)is also considerable for JSC.
