According to the analysis regarding the basic researches and clinical literature of moxibustion smoke in recent ten years, it was found the low-concentration moxibustion smoke had unique application values for air disinfection, infectious diseases and skin diseases, etc. However, certain chemical components of long-time high-concentration moxibustion smoke could cause toxic and adverse effects on respiratory system, immune system and circulation system. Therefore, the safety effects of moxibustion smoke were summarized, hoping to provide references for further clinical researches and evidence-based medicine.

Objective To explore the role of transvertebral transposition of the spinal cord in the treatment of the pa?tients suffering from angular kyphoscoliosis with neurologic deficit. Methods Twelve patients with at least 1 year follow?up, in?cluding 5 females and 7 males, suffering from neurologic deficit secondary to angular kyphoscoliosis underwent transvertebral transposition of the spinal cord and posterior correction from January 2005 to June 2013 were retrospectively analyzed. The initial age averaged 21±14 years. The etiologies of deformity were congenital kyphoscoliosis in 9 patients, idiopathic kyphoscoliosis in 3 patients. Preoperative spinal cord function graded by Frankel criteria was 3 cases of grade C and 9 of grade D. The initial major curve was 79.4°±16.2° with a global kyphosis of 68.3°±25.0°. The change of distance between spinal cord and canal on the convex side at the apex was measured on MR images to evaluate the efficacy of transposition;in addition, Cobb angle on coronal and sagit?tal plane was evaluated before surgery, on discharge and at the last follow?up. Results All patients were followed up for 2 years on average (1-5 years). The post operation spinal function evaluated by Frankel criteria were as follow:with grade C of 1 case, grade D of 4 cases and grade E of 7 (7 cases changed one grade, 1 case changed two grades, 4 cases did not change obvious). At the last follow?up, all the cases got obvious recovery of spinal function, with 1 case of grade C and 11 of grade D (10 cases changed one grade, 2 cases changed two grades). The distance between spinal cord and canal on the convex side at the apex changed from 11.9±6.4 mm to 9.8±6.9 mm. After surgery, the major curve improved to 39.3°±15.1° with 50.3%±20.5%correction rate, and the mean loss of correction was 6.1%±7.5%. The mean kyphosis was 41.3°±16.6°, demonstrating a 39.0%±13.0%correction rate im?mediately after operation, and showing 3.1%±4.2%correction loss at the final follow?up. No neurologic complications or no death occurred intra?and post?operatively. No screw or rod fracture, instrumentation loosening and pseudarthrosis were found during fol?low?up. Conclusion Transvertebral transposition of the spinal cord and posterior correction is a useful procedure for the recovery of neurologic deficit secondary to angular kyphoscoliosis, with good results of deformity correction.

OBJECTIVE:To establish the HPLC fingerprints for Huobahuagen tablets intermediate. METHODS:HPLC was per-formed on Inertsil ODS-4 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid (gradient elution) at the flow rate of 0.75 mL/min.

OBJECTIVETo assess the association of copy number variations of SMN1, SMN2, NAIP, GTF2H2 and H4F5 genes with clinical classification of spinal muscular atrophy in children, and determine the copy number of the SMN gene among pregnant women. A carrier screening was also performed in Sichuan province.

METHODSThe copy number variations of the above genes among 53 confirmed SMA patients were determined with MLPA technique. The copy number variations were analyzed by the Fisher's exact test. Deletion of exon 7 in the SMN1 gene was screened with denaturing high performance liquid chromatography (DHPLC) for 427 pregnant women.

RESULTSAmong the 53 cases of type I, II, and III SMA patients, the rate of homozygous deletion of both exons 7 and 8 of the SMN1 gene were 100%, 94.44% and 87.50%, respectively, whereas those of homozygous deletion of exon 7 of SMN1 gene were 0, 5.56%, and 12.50%, respectively. The patients with 1, 2, 3, and 4 copies of exon 7 of the SMN2 gene were 11.32%, 67.92%, 13.21% and 7.55%, respectively. The patients with 0, 1, and 2 copies of exon 5 of NAIP gene were 11.32%, 62.26%, and 26.42%, respectively. No deletion was detected in GTF2H2 or H4F5 genes. The heterozygous loss rate of exon 7 in SMN gene in the pregnant women population of Sichuan region was approximately 2.11%.

CONCLUSIONCopy number variations of SMN2 and NAIP genes in patients are related to SMA clinical types (P < 0.05). In contrast, there was no relationship between SMA clinical types and deletion of exons 7 and 8 in the SMN1 gene (P > 0.05). Analysis of copy number change in SMN1 gene can assist SMA carrier screening. However, when the general population without SMA family history is screened for disease-causing genes, it should be noted that the type "2+0" carriers may affect the screening result, and the result should be interpreted with caution.

OBJECTIVETo detect potential mutations of fibrillin-1 (FBN1) gene in a child with Marfan syndrome (MFS) and explore its molecular pathogenesis.

METHODSThe 66 exons of the FBN1 gene were analyzed by direct sequencing. SIFT and PolyPhen-2 were used to predict the structural and functional changes at the protein level.

RESULTSA novel heterozygous mutation c.3998 G>A (p.Cys1333Tyr) was found in exon 32 in the child. The same mutation was not found among his unaffected family members and 683 healthy controls. Multiple sequence alignment showed that this novel mutation was located in a highly conserved region of the FBN1 protein across various species and may induce structural change to a functional domain.

CONCLUSIONThe novel c.3998G>A (p.Cys1333Tyr) mutation of the FBN1 gene probably predisposed the MFS in the child. Above finding has enriched the spectrum of FBN1 mutations.

OBJECTIVE: To screen for MYOC gene variants among sporadic patients with primary open angle glaucoma (POAG). METHODS: For 398 patients with POAG, Sanger sequencing was applied to detect potential variants of the MYOC gene. RESULTS: Eight patients (2.0%) were found to harbor variations of the MYOC gene. These included five types of variants, among which c.667C>T (p.Pro223Ser) and c.1138G>T (p.Asp380Tyr) were novel. c.382C>T (p.Arg128Trp), c.1109C>T(p.Pro370Leu) and c.1130C>A (p.Thr377Lys) were previously associated with POAG. Alignment of amino acid sequences of MYOC proteins of various species revealed that the two novel variants have occurred at highly conserved positions. c.1138G>T was predicted to be possible pathogenic by Bioinformatic analysis. CONCLUSION Two novel variants of the MYOC gene were detected among sporadic POAG patients, which enriched its variant spectrum.

Objective To analyse the prognosis and risk factors of lung cancer with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Tongchuan City, and to provide a theoretical basis for improving the prognosis of patients with lung cancer complicated with AECOPD. Methods A total of 280 patients with lung cancer combined with AECOPD admitted to Tongchuan People's Hospital from January 2021 to August 2022 were selected and divided into survival group and death group according to whether the patients survived during hospitalization. Serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA 21-1) and other tumor markers were compared between the two groups. Lung function was measured by lung function instruments, and the levels of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC and other lung function indicators were compared between the two groups. The patients' clinical data were collected from the medical record system, and univariate analysis and logistic regression were used to analyze the independent risk factors affecting the prognosis of patients with lung cancer complicated with AECOP. Results The values of FEV1, FVC and FEV1/FVC in the death group were significantly lower than those in the survival group (P<0.05). Serum CEA and CYFRA 21-1 levels in the death group were significantly higher than those in the survival group (P<0.05). Multiple logistic regression analysis showed that albumin level <35 g/L (OR=2.728), TNM stage III to IV (OR=2.416), multidrug-resistant bacterial infection (OR=2.982), and GOLD grade III to IV (OR=3.417) were independent risk factors for death in patients with lung cancer complicated with AECOPD in Tongchuan City (P<0.05). Conclusion Patients with lung cancer complicated with AECOPD in Tongchuan City have a high risk of death during hospitalization, especially patients with TNM stage III to IV and GOLD grade III to IV. Multi-drug resistant bacteria infection should be actively controlled to improve the albumin level of patients, which is conducive to the prognosis of patients.
