AIM To observe the effects of Guhoukang Granules (Eucommiae Cortex,Dipsaci Radix,Corni Fructus,etc.) on bone metabolism indexes of the geriatric femoral intertrochanteric fracture.METHODS A total of eighty patients meeting the inclusion criteria,cured with fixed operation of proximal femoral anti-rotation nail and given basic care,were divided randomly and equally into two groups:experiment group (Guhoukang Granules ) and control group (calcium carbonate D3 tablets).Three months made a course.Osteocalcin (OC),calcitonin (CT),bone-specific alkaline phosphatase (BALP),total procollagen type 1 aminoterminal propeptide (tPINP),β isomer of the C-terminal telopeptide of type Ⅰ collagen (β-CTX),and intact parathyroid hormone (iPTH),were examined before and after three months,respectively.RESULTS There were no significant statistical difference in the levels of OC,CT,BALP,tPINP,β-CTX and iPTH before operation in both groups.The levels of OC,CT,BALP,tPINP in the experiment group obviously increased and the levels of β-CTX,iPTH markedly decreased after the operation,and were better than those in the experiment group pre-operation and in the control group after the operation.The control group had no improvement in bone metabolism indexes pre-and post-operation.CONCLUSION Guhoukang Granules can improve bone metabolism of the geriatric femoral intertrochanteric fracture and facilitate the recovery of the fracture.

Objective:To observe the clinical characteristics of primary retinitis pigmentosa (RP) complicated with glaucoma.Methods:A retrospective clinical study. From June 2008 to March 2020, the diagnosis of primary RP were included in the diagnosis confirmed by the eye examination of West China Hospital of Sichuan University included 4794 eyes of 2432 patients. Among them, 4679 eyes (97.2%, 2364/2432) were in 2364 cases with RP alone, and 115 eyes were in 68 cases with RP combined with glaucoma (2.80%, 68/2432). All affected eyes underwent best corrected visual acuity (BCVA) and intraocular pressure examination. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into the logarithmic minimum angle of resolution (logMAR) visual acuity during statistics. The 67 eyes of 40 patients with RP and glaucoma with complete follow-up data were analyzed to observe the proportion of different glaucoma types, logMAR BCVA, intraocular pressure and other clinical characteristics, as well as treatment methods and post-treatment intraocular pressure control. After treatment, the intraocular pressure ≤21 mm Hg (1 mm Hg=0.133 kPa) was regarded as intraocular pressure (IOP) control; >21 mm Hg was regarded as uncontrolled IOP.Results:Among the 67 eyes of 40 cases with complete follow-up data, 5 cases (7 eyes) with primary open-angle glaucoma (10.45%, 7/67), 56 cases (58 eyes) with angle-closure glaucoma (ACG) (86.57%, 58/67), 4 cases (4 eyes) with neovascular glaucoma (5.97%, 4/67), 2 of them had both ACG and neovascular glaucoma. Among 58 ACG eyes, 17 eyes were acute ACG (25.37%, 17/67), 21 eyes were chronic ACG (31.34%, 21/67), and 2 eyes were suspicious angle closure (2.99%, 2/67), lens dislocation secondary to angle-closure glaucoma in 8 eyes (11.94%, 8/67), chronic angle-closure glaucoma after anti-glaucoma surgery, intraocular lens shift in 5 eyes (7.46%, 5/67), 5 eyes (7.46%, 5/67) secondary to glaucoma with true small eyeballs. The logMAR BCVA 3.50 of the affected eye,<3.50->2.00, ≤2.00-≥1.30,<1.30->1.00, ≤1.00- 0.52,<0.52 were 9 (13.43%, 9/67), 30 (44.78%, 30/ 67), 7 (10.45%, 7/67), 4 (5.97%, 4/67), 11 (16.42%, 11/67), 6 (8.96%, 6/67) eyes, which correspond to mean intraocular pressure were 32.31±11.67, 30.15±14.85, 28.17±13.19, 31.50±17.25, 18.71±8.85, 14.12±4.25 mm Hg. Among 67 eyes, 37eyes (55.22%, 37/67), 18eyes (26.86%, 18/67), and 6 (8.96%, 6/67) eyes underwent surgery, medication alone, and peripheral iris laser perforation treatment, respectively. The treatment of 6 eyes was abandoned (8.96%, 6/67). Malignant glaucoma occurred in 3 eyes (8.11 %, 3/37) after the operation, all of which were after trabeculectomy of the ACG eye. After treatment, intraocular pressure was controlled in 37 eyes (55.22%, 37/67), 19 eyes were not controlled (28.36%, 19/67), and 11 eyes were lost to follow-up (16.42%, 11/67).Conclusions:The incidence of glaucoma in patients with primary RP is 2.80%. ACG is more common, and the combined lens dislocation or intraocular lens shift is more common.

Objective:To investigate the clinical effect of bridging fixation with locking plate for the Seinsheimer type V subtrochanteric femoral fracture. Methods:From March 2009 to September 2014,18 cases of Seinsheimer type V sub-trochanteric femoral fracture were treated by open reduction and bridging fixation with locking plate through proximal and distal approach including 16 males and 2 females with an average age of 41 years old ranging from 22 to 67 years old. Among them , 12 cases caused by traffic accident,5 cases by falling,1 case by heavy aboving. All cases were fresh and closed fractures. Time between injury and operation was from 4 to 9 days with an average of 6.2 days. Of them ,11 cases were fixed with reverse LISS and the other 7 cases were fixed with anatomical locking plates of proximal femur. Results:The mean time of operation was 110 min (ranged from 90 to 155 min). The mean blood loss during operation was 425 ml (ranged from 350 to 650 ml) and 16 cases got blood transfusion which was meanly 300 ml. The mean hospital time was 14 days (ranged from 12 to 18 days). The mean duration of followed up was 11.8 months (ranged from 8 to 22 months). The mean time of bone union was 6.6 months (ranged from 5 to 8 months). There was not any complication such as infection,implant failure,hip varus,external rotation deformity of low limb or fat embolism. The Sanders hip scores were 53.22±6.48,the result was excellent in 12 cases and good in 6 cases at the last follow up. Conclusion:Under the principle of biological osteosynthesis ,treatment of Seinsheimer type V sub-trochanteric femoral fracture with bridging locking plate fixation has such advantages as high mechanism ,less interference of blood supply,stable fixation and little complication. It is a safe and idea way for the treatment of the Seinsheimer type V sub-trochanteric femoral fracture.

Objective:To explore the clinical features and genetic etiology of a fetus with 15q11q13 complex duplication syndrome.Methods:A fetus diagnosed with 15q11q13 duplication syndrome at Ningbo Women and Children′s Hospital on April 19, 2023 was selected as the study subject. Clinical data was collected, and the fetus was subjected to invasive prenatal diagnosis including G-banded karyotyping and chromosomal microarray analysis(CMA). Following the discovery of chromosomal duplication, trio-whole exome sequencing was carried out to exclude single base variants and confirm the parental original of the duplication. Optical genome mapping was also performed to delineate the structural arrangement of the duplication. Relevant literature was searched in the PubMed, Wanfang Medical Network and CNKI databases using "15q11q13", "duplication", "hexasomy" and "Six fold repetition" as the key words from January 1, 2000 to August 1, 2023 for a review of previously reported 15q11q13 hexasomy cases. This study was approved by Medical Ethics Committee of the Ningbo Women & Children′s Hospital (Ethics No. EC2020-048).Results:The fetus was found to have a mosaicism karyotype of 48, X?, + mar, + idic(15)(q13)[33]/ 47, X?, + idic(15)(q13)[17]. CMA and trio-WES have all shown a six-fold duplication in the PWS/AS critical region (PWACR) at 15q11.2q13.2 and quadruple duplication of 15q13.2q13.3 region, which have derived from its mother and formed supernumerary marker chromosomes (SMCs). Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the 15q11.2q13.2 sixfold duplication was classified as pathogenic, whilst the 15q13.2q13.3 quadruple duplication was classified as variant of uncertain significance. Literature search has identified 11 cases of 15q11q13 duplication involving hexasomy of the PWACR, with all cases showing mental retardation, language delay and hypotonia, and most of them also had motor retardation, epilepsy and mild facial dysmorphism.Conclusion:Hexasomy for the PWACR combined with tetrasomy of 15q13.2q13.3 probably underlay the left hand polydactyly, polyhydramnios and intrauterine growth retardation in this fetus.

By analysing the similarity between defense qi and leukocytes in terms of function， site of action， and circadian rhythm， it is proposed that in traditional Chinese medicine （TCM）， the pathogenesis of leukopenia is defense qi deficiency. By analyzing the relevant discussions on the generation and transmission of defense qi in TCM classics， it is believed that the original qi in lower jiao （焦） is the source of defense qi， while the water and grain qi in middle jiao enriches defense qi， and the upper jiao transmits and distributes defense qi to the whole body. Therefore， when treating leukopenia after chemotherapy with TCM， Guilu Erxian Gelatin （龟鹿二仙胶） and Yougui Pill （右归丸） are often used to tonify the kidney and supplement essence， and moxibustion at Guanyuan （CV 4） and Qihai （CV 6） is usually accompanied to replenish the original qi in lower jiao and enrich the source of defense qi. Guipi Decoction （归脾汤）， Buzhong Yiqi Decoction （补中益气汤）， Shenling Baizhu Powder （参苓白术散）， and Sijunzi Decoction （四君子汤） are often suggested to strengthen spleen and replenish qi， in combination with moxibustion at Zhongwan （CV 12） and Zusanli （ST 36） to transport the spleen and stomach in the middle jiao to enrich the defense qi. Modified Guizhi Decoction （桂枝汤） to harmonize nutrient and defensive aspects is often used， and moxibustion at Dazhui （GV 14） and Feishu （BL 13） or scraping is added to dredge the striae and interstice in the upper jiao and promote transmission and dissemination of the defense qi. Considering the whole process of generation and distribution of defense qi， it is suggested to choose the most appropriate treatment modality flexibly， and combine internal treatment with external treatment， in order to provide ideas for the treatment of leukopenia in tumour patients.

Objective To study the distribution and drug resistance of pathogens in patients with lung cancer,and analyze the prevention strategies. Methods A total of 312 cases of lung cancer patients with infection treated in our hospital from January 2017 to January 2021 were selected as the research objects.The lower respiratory tract secretions,urine and feces were collected for pathogen culture and drug sensitivity test;the distribution and drug resistance of pathogens were analyzed,and the corresponding prevention strategies were formulated. Results Of the 312 patients, 165 (52.88%) had respiratory tract infection, 79 (25.32%) had oropharyngeal infection, and 68 (21.80%) had urinary tract infection.The highest proportion was respiratory infection.Among the 312 patients,398 pathogens were detected of which 212 Gram-positive bacterias (53.27%)were found of which Staphylococcus epidermidis(15.58%)and Staphylococcus aureus(13.07%)accounted for a relatively high proportion. Among 175 Gram-negative strains,Klebsiella pneumoniae(15.94%)and E.coli (10.05% ) accounted for a large proportion.The resistance rate of Gram-positive bacteria,such as Staphylococcus epidermidis and Staphylococcus aureus,to amikacin,gentamicin and penicillin,was more than 50%,which was sensitive to vancomycin. Gram negative bacteria such as Klebsiella pneumoniae and E.coli have high resistance to common antibiotics,and the drug resistance rate to cefepime and cefazolin is more than 50%,and sensitive to imipenem/cilastatin and imipenem/cilastatin.Among 11 fungi,4 cases were resistant to fluconazole , 36.36%,3 to itraconazole,27.27%,0 to ketoconazole and voriconazole,0.00%. Conclusion The distribution and drug resistance of pathogenic bacteria in patients with lung cancer infection in our hospital have certain characteristics,in which Gram-positive bacteria are mainly Staphylococcus epidermidis and Staphylococcus aureus,Gram-negative bacteria are mainly Klebsiella pneumoniae and Escherichia coli,and there are also a small number of fungal infections.Therefore,we should strengthen the monitoring of etiology and drug resistance,and strengthen the management of hospital disinfection Drug sensitivity results of patients,rational use of antibiotics,so as to improve the treatment effect and reduce the risk of infection.

ObjectiveTo investigate the whole genomic characteristics and phylogenetic relationships of clinical isolates of enteroaggregative Escherichia coli (EAEC) in diarrhea outpatients in Pudong New Area, Shanghai. MethodsBased on the diarrheal disease surveillance network in Pudong New Area, Shanghai, whole-genome sequencing was performed on a total of 55 EAEC strains isolated from fecal samples of the diarrhea outpatients from January 2015 to December 2019. The genome analyses based on raw sequencing data encompassed genome size, coding genes, dispersed repeat sequences, genomic islands, and protein coding regions, and pan-genome analyses were conducted simultaneously. Contigs sequences assays were performed to analyze molecular characteristics including serotypes, antibiotic resistance genes, and virulence factors. The phylogenetic clusters and multilocus sequence typing (MLST) were identified, and a phylogenetic tree was constructed. ResultsEAEC exhibited an open pan-genome. The predominant serotype of EAEC in diarrhea outpatients in Pudong New Area was O130:H27, and the carriage rate of β-lactam resistance genes was the highest (67.27%, 37/55). A total of 29 virulence factors and 106 virulence genes were identified, phylogenic group B1 was the predominant group, and clonal group CC31 was the dominant clonal group. The strain distribution was highly heterogeneous. ConclusionThe genomic characteristics of EAEC displayed significant strain polymorphism. It is necessary to develop effective strategies for differential diagnosis and improve detection capabilities for infection with EAEC of different serotypes and genotypes.
