BACKGROUND :
Pulmonary tuberculosis (TB) is among the top 10 causes of death worldwide. Prolonged use and noncompliance with TB treatment have a potential risk for pulmonary fungal coinfection. This study aimed to evaluate fungal coinfection in pulmonary TB patients in Indonesia referred to the Clinical Microbiology Laboratory, Faculty of Medicine, Universitas Indonesia, Jakarta, during 2018–2022.
METHODS :
A cross-sectional study was conducted to compare 5 years of data collected at the Clinical Microbiology Laboratory, Faculty of Medicine, Universitas Indonesia. A total of 7,440 sputum specimens from various clinical sites were examined from 2018 to 2022. Sputum specimens from TB patients were prepared for microscopic examination using ZN staining to detect AFB. Culture and antimicrobial susceptibility of TB were performed on LJ agar. Fungal detected on microscopic examination and culture were assessed as coinfections.
RESULTS :
ZN staining to detect M. tuberculosis in clinical specimens has high specificity (98.4%) but low sensitivity (60.6%). Drug resistance in TB patients remains a problem, which can increase the risk of fungal infections. In 2018–2019, TB and fungal coinfections were more common in polyresistant TB cases. In 2020–2021, TB and fungal coinfections were found in all resistant TB cases, most commonly in XDR-TB cases. In 2022, TB and fungal coinfections were found in monoresistant and polyresistant patients. Candida spp. was found in 6.2% of positive TB cases, and all were found in resistant TB.
CONCLUSIONS
Increasing MDR- and XDR-TB are risk factors for fungal coinfection and must be detected early for better TB management in Indonesia.

Objective:
To establish a method for the determination of anisodamine, atropine, and scopolamine in infant complementary foods and formula milk powder by solid-phase extraction combined with liquid chromatography-tandem mass spectrometry.
Methods:
Commercially available infant complementary foods (biscuits, noodles, and rice flour) and formula milk powder were collected. The samples were homogenized, extracted ultrasonically with 0.5% formic acid-80% aqueous methanol solution, and purified using polymer-based mixed-mode cation-exchange solid-phase extraction cartridges. Gradient elution was performed with 0.02% formic acid-1 mmol/L ammonium formate aqueous solution and methanol as mobile phases. The target compounds were separated using an XBridgeTM BEH C18 column (150 mm×3 mm, 2.5 μm), detected by positive electrospray ionization multiple reaction monitoring mode, and quantified using the isotope internal standard method.
Results:
When 0.5% formic acid-80% aqueous methanol solution was used for extraction and the loading volume was 5 mL, the peak areas and average spiked recovery rates of the target compounds were relatively high. The matrix effects of infant food were evaluated using the optimized method. Noodles showed a matrix suppression effect, whereas biscuits, rice flour, and formula milk powder exhibited matrix effects close to 100%, which were corrected by isotope internal standard quantification. The three tropane alkaloids had good linear relationships in the range of 0.1-50 ng/mL, with all correlation coefficients greater than 0.999. The limits of detection and limit of quantification were 0.1 and 0.3 μg/kg, respectively. At spiked concentrations of 0.3, 8.0, and 40.0 μg/kg, the average spiked recovery rates of anisodamine, atropine, and scopolamine were 95.7%-102.6%, 93.2%-104.7%, and 95.5%-104.1%, respectively, with relative standard deviations of 1.4%-8.5%, 1.5%-8.4%, and 3.1%-8.5%, respectively. None of the three tropane alkaloids were detected in 100 infant complementary food samples. Among 60 infant formula milk powder samples, atropine and scopolamine were detected in one sample, while anisodamine was not detected.
Conclusions
The method is simple, accurate, and sensitive, and can effectively eliminate the interference of complex matrix effects. It can be applied to the quantitative determination of tropane alkaloids in infant foods.

BACKGROUND AND OBJECTIVE
Understanding the normal anatomy and size of the extrahepatic biliary tree is vital for surgeons to make informed decisions regarding the necessity of additional procedures beyond cholecystectomy. The extrahepatic bile duct (EHBD) comprises the common hepatic duct (CHD) and the common bile duct (CBD), with the former formed by the convergence of the right and left hepatic ducts and the latter extending from the CHD to the duodenum. A normal diameter is indicative of the absence of any signs of obstruction in the EHBD, and the determination of the average range for these ducts are essential for identifying pathologies that may require further surgical intervention. Cholecystolithiasis is a common condition managed at the Philippine General Hospital (PGH). Trans-abdominal ultrasonography is frequently utilized to diagnose cholecystolithiasis, and it can also be used to determine the size of the common bile duct. Knowledge of the normal CBD diameter aids clinicians in distinguishing obstructed bile ducts from normal ones, prompting further diagnostic tests for improved patient management. However, there is limited data on the average diameter of the CBD among Filipino patients with this condition. The study aimed to determine the mean diameter of the common bile duct and common hepatic duct among patients diagnosed with cholecystolithiasis with no signs of obstruction in the EHBD managed at the Philippine General Hospital.
METHODSThis prospective cross-sectional study included 80 patients who underwent cholecystectomy with intraoperative cholangiography. The CBD and CHD diameters were measured using intraoperative ultrasonography, and the data were analyzed using descriptive statistics and independent t-test.
RESULTSThe mean diameter of the CBD was 5.17 mm, with a range of 2.7-10 mm (1.41) mm. The mean diameter of the CHD was 4.71 mm, with a range of 2.3- 10 mm (1.59) mm. There was no significant difference in the CBD and CHD diameters between male and female patients, and across different age groups.
CONCLUSIONIn patients with cholecystolithiasis managed at the PGH, the mean diameter of the CBD and the CHD was 5.17 mm and 4.71 mm, respectively, with no significant difference between genders and age groups. The mean diameter of the CBD among Filipino patients with cholecystolithiasis is similar to those reported in other countries. These findings may have clinical implications for the management of patients with cholecystolithiasis, particularly in the planning of endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy. Further studies with larger sample sizes and different populations are recommended to validate these results. These findings can aid clinicians in determining the need for pre-operative Magnetic Resonance Cholangiopancreatography (MRCP) or selective intraoperative cholangiography to detect extrahepatic bile duct obstruction.

OBJECTIVE:
Huachansu injection (HCSI), a promising anti-cancer Chinese medicine injection, has been reported to have the potential for reducing the toxicity of chemotherapy and improving the quality of life for colorectal cancer (CRC) patients. The objective of this study is to explore the synergistic and detoxifying effects of HCSI when used in combination with irinotecan (CPT-11).
METHODS:
To investigate the effect of HCSI on anti-CRC efficacy and intestinal toxicity of CPT-11, we measured changes in the biological behavior of LoVo cells in vitro, and anti-tumor effects in LoVo cell xenograft nude mice models in vivo. Meanwhile, the effect of HCSI on intestinal toxicity and the uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) expression was investigated in the CPT-11-induced colitis mouse model. Subsequently, we measured the effect of HCSI and its 13 constituent bufadienolides on the expression of UGT1A1 and organic anion transporting polypeptides 1B3 (OATP1B3) in HepG2 cells.
RESULTS:
The combination index (CI) results showed that the combination of HCSI and CPT-11 exhibited a synergistic effect (CI < 1), which significantly suppressing the LoVo cell migration, enhancing G2/M and S phase arrest, and inhibiting tumor growth in vivo. Additionally, the damage to intestinal tissues was attenuated by HCSI in CPT-11-induced colitis model, while the increased expression of UGT1A1 in HepG2 cells and in mouse was observed.
CONCLUSION
The co-therapy with HCSI alleviated the intestinal toxicity induced by CPT-11 and exerted an enhanced anti-CRC effect. The detoxifying mechanism may be related to the increased expression of UGT1A1 and OATP1B3 by HCSI and its bufadienolides components. The findings of this study may serve as a theoretical insights and strategies to improve CRC patient outcomes.

OBJECTIVE:
To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality.
METHODS:
A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters.
RESULTS:
The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights.
CONCLUSION
Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

Objective To establish a sandwich enzyme-linked immunosorbent assay (ELISA) method for the quantitative detection of Chromogranin A (CHGA) in saliva, and to explore its preliminary application in the testing of saliva samples. Methods Recombinant human CHGA protein was used to immunize BALB/c mice, and monoclonal antibodies (mAbs) were prepared and screened using conventional hybridoma technology. A double-antibody sandwich ELISA detection method was constructed, and the matrix effect of saliva samples was optimized. This method was then applied to detect the concentration of CHGA in the saliva of stressed individuals. Results Twenty-one stable hybridoma cell lines secreting high affinity anti-human CHGA antibodies were obtained. A pair of detection antibodies with the best effect was selected, and the optimal coating concentration was determined to be 10 μg/mL, with the optimal dilution of detection antibodies being 1:32 000. The accuracy and reproducibility of this method were verified, with both intra-batch and inter-batch variation coefficients less than 15×, and the recovery rate between 80× and 120×. The matrix effect was further optimized to make it suitable for saliva sample detection. Saliva samples from individuals in different stress states were collected, and the CHGA levels were detected using the method established in this study, indicating its potential to reflect the intensity of stress. Conclusion A reliable saliva CHGA ELISA detection method has been successfully established, and its potential as a biomarker in stress-related research has been preliminarily explored.

Chinese Journal of Cellular and Molecular Immunology 2025;41(6):531-535
Objective To investigate the causal relationship between serum total bile acid (TBA) levels and gastric cancer (GC) using regression discontinuity design (RDD). Methods A total of 1244 GC patients and 1333 healthy controls were included in the study. Demographic characteristics, gallbladder disease history, tumor markers, and serum TBA levels were collected from both groups. Logistic regression was used to construct a risk prediction model to estimate the risk of GC. RDD was employed with serum TBA as the grouping variable and the individual risk of developing GC as the outcome variable. Results The predictive factors in the GC risk prediction model included age, sex, body mass index(BMI), serum TBA, carcinoembryoniv antigen(CEA), alpha fetoprotein(AFP), carbohydrate antigen 199(CA199), and CA125. Serum TBA was identified as an independent risk factor for GC (OR=1.054, 95% CI: 1.030 to 1.079). RDD analysis indicated that when serum TBA levels reached 8 μmol/L, the probability of developing GC increased sharply by 23.7%. The breakpoint remained statistically significant following validity and robustness assessments. Conclusion The study demonstrates a positive causal relationship between serum TBA levels and GC, when the serum TBA level reaches 8 μmol/L, the risk of an individual developing GC increases sharply.

Discovery of spermatozoa during the 17 th century led to developing technologies for semen analysis in the early 1900s, and then, standard techniques were implemented during the 20 th century. Semen analysis has a pivotal role in the male infertility evaluation, and azoospermia is an important finding. Azoospermia is identified in 15% of infertile men. However, the accurate laboratory assessment of azoospermia poses certain technical challenges. Laboratories currently perform semen assessment with great variability; thus, a standard method should be used. Planning suitable management and determining the cause of infertility require a precise evaluation of azoospermia. This review aims to address the definition of azoospermia and highlight laboratory methods in the assessments of azoospermia. Basic methods such as centrifugation, repeat pellet analysis, and staining and advanced methods such as genetic testing and biomarkers have been discussed. These methods have helped in standardizing the protocol for accurate azoospermia assessments with less variability.

Approximately 15% of men in the general population have varicoceles, and varicoceles are diagnosed in 40% of men presenting for fertility evaluations. One percent of men in the general population are azoospermic, and 15% of men presenting for fertility evaluations are diagnosed with azoospermia. This article aims to review the impact of varicoceles on testicular function in men with azoospermia, the impact of varicocele repair on the semen parameters of azoospermic men, and the impact of varicocele repair on sperm retrieval and pregnancy outcomes when the male partner remains azoospermic after varicocele repair.

According to the World Health Organization (WHO) manual, sperm concentration should be measured using an improved Neubauer hemocytometer, while sperm motility should be measured by manual assessment. However, in China, thousands of laboratories do not use the improved Neubauer hemocytometer or method; instead, the Makler counting chamber is one of the most widely used chambers. To study sources of error that could impact the measurement of the apparent concentration and motility of sperm using the Makler counting chamber and to verify its accuracy for clinical application, 67 semen samples from patients attending the Department of Andrology, West China Second University Hospital, Sichuan University (Chengdu, China) between 13 September 2023 and 27 September 2023, were included. Compared with applying the cover glass immediately, delaying the application of the cover glass for 5 s, 10 s, and 30 s resulted in average increases in the sperm concentration of 30.3%, 74.1%, and 107.5%, respectively (all P < 0.0001) and in the progressive motility (PR) of 17.7%, 30.8%, and 39.6%, respectively (all P < 0.0001). However, when the semen specimens were fixed with formaldehyde, a delay in the application of the cover glass for 5 s, 10 s, and 30 s resulted in an average increase in the sperm concentration of 6.7%, 10.8%, and 14.6%, respectively, compared with immediate application of the cover glass. The accumulation of motile sperm due to delays in the application of the cover glass is a significant source of error with the Makler counting chamber and should be avoided.
