[Summary] A selection of 528 unrelated subjects were enrolled(198 males, 330 females) with the mean age of(52. 23 ± 13. 41) years old. According to body mass index, 253 persons belonged to the normal weight group and 275 persons overweight/ obesity group. A total of 10 SNPs in CIDEB and CIDEC genes were detected. SHEsis online were used to get the haplotypes of these two genes. The relationship between above SNPs and obesity were analyzed under additive inheritance pattern. The main effects and interaction on obesity induced by two genes’ haplotypes were analyzed by logistic regression. rs2144493 in CIDEB gene was associated with obesity, C was a protective alleles, OR (95% CI) equals 0. 722(0. 525-0. 992). CCTT haplotype of CIDEB gene carriers and GCG haplotype of CIDEC gene carriers were more prone to obesity or overweight, there was an interaction between the haplotypes of 2 genes. CIDEB, CIDEC haplotypes may play independent and interactive roles in causing obesity.

BACKGROUND: Hallux valgus is a common orthopedic disease, and its causes are complex and treatment is varied. The mechanical analysis of hallux valgus is an issue of concern. The finite element analysis makes it predictable to treat hallux valgus. OBJECTIVE: To explore the clinical application of finite element analysis in biomechanical study of hallux valgus.METHODS: The first author searched CNKI and PubMed databases from January 1980 to March 2017 using the key words of "finite element, hallux valgus" in English and Chinese, respectively. The repetitive, irrelevant and low-quality articles were excluded. Finally 33 eligible articles were included in accordance with the inclusion criteria, and the critical issues of finite element analysis applied in hallux valgus were reviewed. RESULTS AND CONCLUSION: (1) There are many researches concerning finite element of hallux valgus, which mostly require physicians to work with engineers. These methods are already very mature, but most of the model and material properties of the data come from foreign researches. (2) The finite element analysis is important and reliable for the etiology of hallux valgus, preoperative planning and prognosis. (3) The finite element model of the hallux valgus is only used on static analysis and gait cycle analysis, the modeling details and definition of material properties still need to be improved.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.
METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.
RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).
CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

To explore a new method for identification of Mongolian patent medicine (MPM) by PCR amplification of specific alleles. Eight kinds of MPM were used to study the identification of "Digeda" raw materials. The total DNA of Lomatogonium rotatum and Corydalis bungeana samples were extracted through modified CTAB method, psbA-trnH sequence was amplified by PCR and sequenced directionally. Specific primer was designed. The DNA of 8 kinds of MPM also was extracted and purified by the commercial DNA purification kits. The rbcL and two pair of specific primers sequences were amplified. The specific amplified products were sequenced in forward directions. All specific sequences were aligned and were analyzed. The results indicated that L rotatum can be identified by specific primers from Digeda-4 Tang, Digeda-8 San, Digeda-4 San, and C. bungeana medicinal materials can be identified by specific primers from Li Dan Ba Wei San, Yi He Ha Ri-12 and A Ga Ri-35. PCR amplification of specific alleles can stably and accurately distinguish raw medicinal materials in MPM.

This study aims to analyze and compare the effect of cell wall-broken decoction pieces, conventional decoction pieces and conventional powder of Rhodiolae Crenulatae Radix et Rhizoma on the intestinal flora of normal mice. The conventional bacterial culture and PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) were adopted for the mice after the oral administration for 14 days. According to the bacterial culture results, the 1/8 dose cell wall-broken decoction pieces group showed fewer Enterococcus and Escherichia coli bacillus but more Lactobacillus and Bifidobacterium than the conventional decoction pieces group and the traditional powder group (P <0.05). Meanwhile, on the basis of the PCR-DGGE results, the 1/8 dose cell wall-broken decoction pieces group revealed the highest Shannon-Wiener index (H) and species richness (S) among the seven groups, with extremely significant differences compared with the normal group (P <0.01), significant differences compared with the conventional decoction pieces group and the conventional powder group (P <0.05) and a high intra-group similarity. In conclusion, the long-term intake of 1/8 dose Rhodiolae Crenulatae Radix et Rhizoma cell wall-broken decoction pieces showed a certain effect in regulating intestinal tract by promoting the growth of Lactobacillus and Bifidobacterium. Furthermore, the intestinal flora community will become more stable.

COVID-19 epidemic continues to spread around the world till these days, and it is urgent to develop more safe and effective new drugs. Due to the limited P3 biosafety laboratories for directly screening inhibitors of virulent viruses with high infectivity, it is necessary to develop rapid and efficient screening methods for viral proteases and other related targets. The main protease (Mpro), which plays a key role in the replication cycle of SARS-CoV-2, is highly conserved and has no homologous proteases in humans, making it an ideal target for drug development. From two different levels, namely, molecular level and cellular level, this paper summarizes the reported screening methods of SARS-CoV-2 Mpro inhibitors through a variety of representative examples, expecting to provide references for further development of SARS-CoV-2 Mpro inhibitors.

OBJECTIVETo study into the genetic polymorphism of DC-SIGN and DC-SIGNR's exon 4 in Chinese hepatitis C patients and its relationship with HCV infection susceptibility.
METHODSPatients with hepatitis C (n=300, group A) and healthy subjects (n=520, group B) were genotyped and analysed for the repeat sequence of polymorphism of DC-SIGN and DC-SIGNR's exon 4 using PCR and DNA sequencing.
RESULTSThe distribution of genotypes and alleles in DC-SIGN's exon 4 in the two groups did not differ significantly (P > 0.05). The difference of allele frequency in DC-SIGNR's exon 4 between the two groups was also not significant (P > 0.05). However, 9/5 genotype distribution frequency of DC-SIGNR's exon 4 in patients with hepatitis C was significantly higher than that in the healthy subjects (P < 0.05).
CONCLUSIONThere is no significant correlation between the genetic polymorphism of DC-SIGN's exon 4 and HCV infection susceptibility. 9/5 genotype distribution frequency of DC-SIGNR's exon 4 in patients with hepatitis C is significantly higher and may be associated with HCV infection susceptibility.
