Objective To explore the clinical features and the management of incision of scalp pain after craniotomy. Methods 129 patients after craniotomy without postoperative neuralgia were involved. The onset, severity, and characteristics of the pain were recorded within 1 week after the craniotomy. Patients with moderate-severe pain were given oxycodone and acetaminophen (treatment group) or rotundine (control) for 3 d. Results 39.5%（51/129）of patients experienced moderate to severe postoperative pain. After treatment, 76.9% （20/26） in treatment group and 36.0% （9/25） in control were released from the pain (P<0.01). The pain intensity differences and sum of pain intensity differences were more in treatment than in control (P<0.01). Conclusion Incision of scalp pain is common after craniotomy. Oxycodone and acetaminophen, called multimodal analgesia is efficacious and safe for it.

Abstract: Objective　In order to understand and master the prevalence of different genotypes and the rate of different drug-resistant Mycobacterium tuberculosis genotypes in Hainan Province, 136 drug-resistant Mycobacterium tuberculosis strains collected in Hainan province in 2022 were genotyped, and to provide scientific basis for tuberculosis prevention and control strategy in Hainan Province. Methods　A total of 136 drug-resistant Mycobacterium tuberculosis strains were collected in Hainan Province. The clinical isolates were genotyped using the Spoligotyping technique, and the drug resistance rates of different genotypes of Mycobacterium tuberculosis were statistically analyzed. Results　Among the 136 strains of drug-resistant Mycobacterium tuberculosis, 54.41% (74/136) belonged to the Beijing types, 27.94% (38/136) to non-Beijing types and newly identified genotypes accounted for 17.65% (24/136). The Beijing type included two genotypes, SIT1 and SIT269 genotypes, accounting for 52.94% (72/136) and 1.47% (2/136) respectively. Among the non-Beijing genotypes, the T type (T1, T2, T3) accounted for 21.32% (29/136), the U type accounted for 6.62% (9/136). Clustering analysis of genotyping results revealed two major clusters, Beijing type and non-Beijing type, as well as several scattered novel genotypes. Clustering analysis of Spoligotyping results classified the 136 drug-resistant strains into 3 clusters, with a clustering rate of 75.74% (103/136). The rates of mono-resistance (MR), poly-resistance (PR), multi-drug resistance (MDR), and other types of drug resistance in Beijing type and non-Beijing type were 41.89% (31/74), 13.51% (10/74), 24.33% (18/74), 20.27% (15/74) and 36.84% (14/38), 15.79% (6/38), 26.32% (10/38), 21.05% (8/38) respectively. Chi-square test results showed no statistically significant differences in drug resistance rates between the Beijing and non-Beijing types (P>0.05). Conclusion　The genotype of Mycobacterium tuberculosis in Hainan Province showed genetic polymorphism, with the main epidemic genotype being SIT1 in the Beijing type. Monitoring of Mycobacterium tuberculosis in this genotype should be strengthened.

Objective To investigate the Human papillomavirus(HPV)infection in different age groups of women in Shenyang, and explore its correlation with cervical biopsy diagnosis.Methods 7 311 women aged 13-85 did HPV test and thin-cytologic test (TCT)in the hospital.Some of them had biopsy detection under electronic colposcopy,and the pathological diagnosis was the golden standard for the diagnosis of cervical lesions.SPSS18.0 statistical software was used for all statistical analysis.Results The infection rate of <30 years old women was significantly higher than that of 30 - <40,40 - <50,≥50 years old women (P <0.05).The most prevalent high-risk HPV genotype in Shenyang were subtype 16,52,58,53,33,31 and 18,and the most prevalent low-risk HPV subtypes were 81,11 and 6.The former 4 subtypes of high-risk HPV infection accounted for 67.3% of all high-risk infection.As to the 4 subtypes with higher infection rate,the infection rate of ≥40 years old women was higher than that of <40 years old(χ2 =20.29,P =0.00).The top two low-risk HPV subtypes accounted for 74.8% of the infections.The mean age of the ICC patients were 48.3,which was statistically different from the other groups(P <0.05).Cervical lesions occured mostly in 40-49 years old,which accounted for 37.1% and was higher than the other agees(P <0.01).HPV16 infection rate increased with the severity of cervical lesions.Conclusion HPV DNA genotyping is a necessary methord for cervical cancer screen,an effective com-plement for precancerous lesions diagnosis which was missed in cytology test,and also an indispensable test for CIN treatment and follow-up after operation.

GATA6 transcription factor belongs to the GATA family and contains 2 conserved zinc ifnger DNA binding domains. GATA6 not only presents in embryonic tissues but also found in heart, lung and pancreas and is essential for the maintenance of their function.The present review focuses on the critical roles of GATA6 in heart development and atrial septal defect to provide theoretical basis for diagnosis and treatment of atrial septal defect.

ObjectiveTo identify mutations ofGATA4 andGATA6 genes in children with isolated congenital atrial septal defect (ASD).Methods From November 2012 to November 2013, 101 patients with ASD (99 unrelated patients and one twin) who were submitted to catheter-based intervention and 100 ethnicity-matched children without congenital heart disease, blood disorders and chromosomal abnormalities were enrolled. The blood was collected. The coding regions and lfanking regions of theGATA4 andGATA6 genes were ampliifed by polymerase chain reaction and sequenced using the dideoxvnucleotide chain termination technique, and then compared with the normal sequence in the Genbank.Results Two novel heterozygous missense GATA6mutations, c. G145A and c. G151A, were identiifed in 2 unrelated ASD patients, which were not present in the controls. These two mutations predicted the conversion of glycine into serine at amino acid residue 49 (G49S) and glutamate into lysine at amino acid residue 52 (K52E). A heterozygous missenseGATA6 mutation c.43 G>C, which caused a conversion from glycine to arginine, was found in 9 ASD patients and 7 controls. A single nucleotide polymorphism c.99G>T, which did not cause amino acid conversion inGATA4 gene, was found.ConclusionsGATA6 gene is an important transcription factor in heart development. The mutation ofGATA6 gene may cause the change of its transcriptional activity, and lead to ASD.

OBJECTIVE: To determine the effect of Gingkgo biloba leaf extract (EGb761) induced delayed preconditioning on cytochrome c oxidase (CcO) expression during myocardial ischemia-reperfusion in rats. METHODS: Four groups (10 in each) of Sprague-Dawley male rats were studied. In the sham group, the rats received no treatment. Rats in the ischemia-reperfusion (IR) group were treated with NS (1.0 mL/kg intravenously) 24 h before ischemia. Rats in the M group were treated with EGb761 (100 mg/kg intravenously) 24 h before the ischemia. In the D group , EGb761-treated rats that received the 5-hydroxydecanoate (5-HD), an inhibitor of mitochondrial KATP channels 15 min before the ischemia. The IR, M, and D groups were subjected to ischemia by 30 min of coronary artery occlusion before 2 h of reperfusion. At the end of the reperfusion, myocardial infarct size was measured. CcO was measured by Western blot. The myocardial ultrastructure was observed under the electron microscope. RESULTS: The infarct size was significantly smaller in the M group [(23.78 ± 4.82)%] than in the I/R group [(37.87 ± 5.92)%] (P<0.05). The CcO protein expression in the myocardium was significantly higher in the M group than in the I/R group(P<0.05). Microscopic examination showed less myocardial damage in the M group than that in the I/R group. The infarct size, CcO protein expression, and myocardial damage had no significant difference between the D group and the I/R group (P>0.05). CONCLUSION EGb761 induced delayed preconditioning attenuates myocardial ischemia-reperfusion injury possibly through up-regulating CcO expression in rats.

RESULTS:There were 12 common peaks in HPLC fingerprints of 10 batches of samples with similarity>0.90. HPLC fingerprint showed a good consistency with the control fingerprint. The contents of 6′-hydroxyl-justicidin B and justicidin B in 10 batches of samples were 1.64-5.84,0.83-2.78 mg/100 mL,respectively. CONCLUSIONS:The established method is simple,accurate,reliable and suitable for quality evaluation of Fufukang spray.

Objective:To explore the clinical efficacy of reconstructing the calcaneocuboid and calcaneonavicular ligaments with the autologous semitendinosus for chronic bifurcate ligament injury.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with chronic bifurcate ligament injury who had been treated by anatomical reconstruction with the autologous semitendinosus from March 2018 to January 2021 at Department of Foot and Ankle Surgery, The Fourth Hospital of Wuhan. There were 4 males and 8 females with an age of (41.4±9.6) years. Seven left and 5 right feet were affected; the time from injury to surgery was (9.3±4.3) months. The surgical efficacy was evaluated based on anteroposterior and lateral imaging assessments of foot weight-bearing at 6 months postoperation, comparison of the visual analogue scale (VAS) pain scores for foot weight-bearing walking and the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scores between preoperation and the last follow-up, stress test for stability of the transverse tarsal joint, recovery of movement, and occurrence of complications.Results:All patients were followed up for (18.4±4.0) months. Their sports activities were completely resumed after postoperative (6.8±3.9) months. Primary wound healing was achieved in all patients. One patient suffered from cutaneous nerve lesion and skin numbness, the symptoms of which disappeared after conservative treatment. Double harmonic curves were observed on the anteroposterior and lateral imaging films of foot weight-bearing in all patients. The spaces in the calcaneocuboid and the calcaneonavicular joints were normal, the articular positions were matched, and the calcaneocuboid joint was stable without recurrence or worsening of displacement. The VAS decreased significantly from preoperative 6.5 (5.6, 7.0) to 0.0 (0.0, 1.0) at the last follow-up, and the AOFAS mid-foot score increased significantly from preoperative (55.6±8.8) points to (92.3±2.6) points at the last follow-up ( P<0.05). The stress test for the stability of the transverse tarsal joint showed joint stability. Conclusion:Reconstruction of the calcaneocuboid and calcaneonavicular ligaments using the autologous semitendinosus is an alternative treatment for patients with chronic bifurcate ligament injury, because it can restore the stability of the bifurcate ligament and obviously improve the foot and ankle functions with limited postoperative complications.

Objective:To compare the clinical features between chronic active Epstein-Barr virus infection(CAEBV) and infectious mononucleosis(IM)in adult patients.Methods:Clinical data from 56 adult IM patients and 14 adult CAEBV patients admitted in the First Affiliated Hospital of Nanjing Medical University during January 2011 to December 2019 were enrolled. Clinical manifestations, laboratory indicators, treatment and outcomes were compared between two groups. Chi-square test and Mann-whitney U test were used to analyze data. Results:The average age of CAEBV patients was higher than that of IM patients [36.0(23.8, 50.5)years vs. 19.0(17.3, 22.8) years; U=90.0, P<0.05]. The symptoms of sore throat, throat congestion, tonsilla enlargement and lymphadenopathy in IM group were more common than those in CAEBV group( χ2=14.088, 16.875, 31.855 and 10.938, all P<0.01). However, the incidence of pulmonary infection, sleepiness/dysphoria and splenomegaly in CAEBV group were significantly higher than those in IM group( χ2=17.217, 5.809 and 6.254, P<0.05 or <0.01). The white blood cell counts, hemoglobin levels, platelet counts, alanine aminotransferase(ALT) and albumin in CAEBV group were significantly lower than those in IM group( U=47.0, 49.5, 158.5, 173.0 and 263.5, all P<0.01). The levels of neutrophil ratio, C-reactive protein, serum ferritin and EBV DNA load in CAEBV group were significantly higher than those in IM group( U=145.0, 140.0, 128.5 and 115.0, P<0.05 or <0.01). The proportions of CD3 + T cell counts and CD8 + T cell counts in CAEBV group were significantly lower compared to those in IM group( U=42.0 and 24.5, P<0.01); the proportions of CD4 + T cell counts, the CD4 + T/CD8 + T cell counts ratio and B lymphocytes in CAEBV group were significantly higher compared to those in IM group( U=29.0, 23.5 and 34.5, P<0.01). Fifty-six IM patients were all cured and discharged from hospital. In CAEBV group, 8 cases died, 3 cases were improved and 3 cases lost follow-up. Conclusions:Patients with IM represent a favorable prognosis, while the prognosis of CAEBV is relatively poor and complication with HLH may occur. For older patients with EBV infection complicated with pulmonary infection, lethargy/irritability, attention should be paid to monitor blood routine, liver function, serum EBV DNA load and peripheral blood lymphocyte subsets.
