Stature is one of the important criteria to individual recognition. And it is always a focus in forensic anthropology. There are some new progresses studies in stature estimation in recent years. We review some studies in stature estimation published in domestic and foreign in the past six years, and find some progresses in stature estimation: (1) As the increasing average human stature, the stature estimation equation is needed to be corrected; (2) Gender, age, race and territory have a great influence to stature estimation. Thus when the study protocol designed, these influences should be considered; (3)The medical imaging technology, especially Computed Tomography, is becoming a new tool to infer stature estimation in forensic anthropology.

Objective: To observe the clinical efficacy of herb-partitioned spreading moxibustion at Baliao points plus climen for diminished ovarian reserve (DOR). Methods: A total of 60 patients with DOR were randomized into a spreading moxibustion group and a Western medicine group by the random number table method, with 30 cases in each group. The Western medicine group was treated with climen, starting from the 5th day of the menstrual cycle for 21 d. The spreading moxibustion group was treated with herb-partitioned spreading moxibustion at Baliao points on the basis of the medication in the Western medicine group, 1 h per time, once a week. The treatment was performed for 1 month as one treatment course in both groups, for 3 courses in total. The serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the patients were measured before and after treatment. The peak systolic velocity (PSV) and resistance index (RI) were also detected. The traditional Chinese medicine (TCM) symptom score was evaluated. The clinical efficacy was evaluated after treatment. Results: The total effective rate in the spreading moxibustion group was 93.3％, which was significantly higher than 80.0％ in the Western medicine group, and the difference between the groups was statistically significant (P<0.05). After treatment, the TCM symptom scores, the serum FSH levels, FSH/LH ratios and RI in both groups decreased, and the intra-group differences were all statistically significant (all P<0.05). The serum E2 level and PSV increased compared with those in the same group before treatment, and the intra-group differences were statistically significant (all P<0.05). After treatment, the TCM symptom score, the serum FSH level, FSH/LH ratio and RI in the spreading moxibustion group were lower than those in the Western medicine group, while the serum E2 level and PSV were higher than those in the Western medicine group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Herb-partitioned spreading moxibustion at Baliao points plus climen can produce valid therapeutic efficacy for DOR. It can improve the clinical symptoms, regulate serum hormone levels and increase ovarian blood perfusion, thus improving ovarian reserve function, producing more significant efficacy than climen alone.

Abstract: Objective　To investigate the clinical characteristics and incidence of Brucella encephalitis and meningitis in children. Methods We report the clinical data of a child with Brucella melitensis meningitis in children, and summarize the incidence, diagnosis methods and treatment of Brucella encephalitis or meningitis in children, taking into account the relevant domestic and foreign literature from January 2014 to December 2020. Results　A 4-year-old girl was admitted to the hospital with status epilepticus on March 15, 2021 because of interrupted right limb numbness for 16 hours and convulsions for 2 hours. She had 2 non-febrile convulsions three months before admission and was diagnosed with epilepsy. This incident was acute, accompanied by low fever, with epilepsy as the main manifestation. Cerebrospinal fluid test suggested central nervous system infection, but the nature of infection could not be determined by routine and biochemistry of cerebrospinal fluid.The cerebrospinal fluid next generation sequencing confirmed that the pathogen of the infection was B. melitensis, which was further verified by the peripheral blood antibody test. After effective antibiotics combined with a full course of treatment, the patient recovered after six months of treatment. A total of 60 articles were retrieved in the database, including 29 in Chinese. During this period, a total of 7 cases of brucellosis in children with nervous system involvement were reported, one of which was a case report, and the other 6 cases were mentioned in the comprehensive analysis of children with brucellosis. Conclusions　Brucella encephalitis or meningitis in children has a low incidence and various clinical features, which are easy to be misdiagnosed or missed.

Muscle fatigue is a common complaint in clinical practice. In humans, muscle fatigue can be defined as exercise-induced decrease in the ability to produce force. Here, to provide a general understanding and describe potential therapies for muscle fatigue, we summarize studies on muscle fatigue, including topics such as the sequence of events observed during force production, in vivo fatigue-site evaluation techniques, diagnostic markers and non-specific but effective treatments.

OBJECTIVECleidocranial dysplasia (CCD) is a dominantly inherited skeletal dysplasia caused by mutations in the osteoblast-specific transcription factor-encoding gene, core binding factor α1 (CBFA1). Over 90 mutations in CBFA1 gene have been published to date in 500 independent cases of CCD, including missense mutations, deletions, insertions, frameshift, and splice mutations. However, mutational screening of the CBFA1 gene is still far from saturation, and more novel mutations will be identified to enrich the insights into the molecular basis for the pathogenesis of CCD. The aim of this study was to explore the clinical and image features and detect the mutations of CBFA1 gene in two CCD families.

METHODIn this study, the clinical features were investigated in two CCD families, radiological and CT examinations regarding osseous malformation were carried out over the entire body of these patients with CCD. Blood (2 ml) was drawn from all affected individuals, unaffected family members and one hundred unrelated normal controls, Genomic DNA was extracted from whole blood with PureGene DNA extraction kit and PCR was performed with eight pairs of PCR primers for exons 0 to 7 of the CBFA1 gene. The mutations of CBFA1 gene were screened in these two CCD families.

RESULT(1) The clinical features of patients with CCD include delayed closure of fontanelles, frontal bossing, dysplasia of clavicles, late tooth eruption, and other skeletal anomalies. X-ray and CT examination showed the bulging calvarium, patent fontanelles, wide cranial sutures, multiple Wormian bones, dental dysplasia or aplasia of clavicles. (2) Two mutations were identified, one is novel missense mutation (c.1259C > T[p.T420I]) in CBFA1 gene exon 7, other (c.577C > T[p.R193X]) was reported in Chinese cases with CCD for the first time.

CONCLUSION(1) The clinical and image features of patients in two CCD families include delayed closure of fontanelles, frontal bossing, dysplasia of clavicles, late tooth eruption, and other skeletal anomalies. (2) The T420I and R193X mutations of CBFA1 were reported, expanding the spectrum of CBFA1 mutations causing CCD.

OBJECTIVETo explore the relationship between genetic polymorphisms of microsomal epoxide hydrolase (mEH) and susceptibility of chronic benzene poisoning (BP).

METHODA case-control study was conducted. 152 BP patients and 152 workers occupationally exposed to benzene without poisoning manifestations were investigated. Polymerase chain reaction-restrained fragment length polymorphism technique (PCR-RFLP) was applied to detect the single nucleotide polymorphisms (SNPs) on c.113 and c.139 of mEH gene.

RESULTSThe risk of BP for individuals carrying mEHc.113 C/C genotype was 0.60 (OR = 0.60, 95% CI: 0.37 - 0.97, P = 0.04) of those carrying T/T and T/C genotypes. In non-smoking population, the risk of BP for subjects carrying mEHc.113 C/C genotype was 0.56 (OR = 0.56, 95% CI: 0.33 - 0.96, P = 0.03) of those carrying T/T and T/C genotypes, and in non-drinking population, the individuals carrying mEHc.113 C/C genotype was 0.51 (OR = 0.51, 95% CI: 0.30 - 0.86, P = 0.01) of those carrying T/T and T/C genotypes.

CONCLUSIONThe subjects carrying mEHc.113 C/C genotype and together with non-smoking or non-drinking habit may have lower risk of chronic benaene poisoning.
